The brand comprehensively embodies the company

Secondly, in the injection molding process, processing companies are usually required to advance funds to purchase relevant raw materials. Large-scale, specialized manufacturing molds require high management capabilities to ensure the standardization and flow of design, and the rationalization of production arrangements. The establishment and formation of a well-known brand requires a lot of investment, and it also requires long-term reputation accumulation and reliability verification. First of all, the processing precision of precision plastic molds at home and abroad is getting higher and higher.

Supporting enterprises that have undergone strict certification by the host manufacturer generally have strong capital and technical strength, so their cooperative relationships are generally relatively strong. Although mold companies in the industry can usually require customers to prepay part of the mold development cost to reduce development risks, the processing equipment for precision molds is expensive and the product itself is complex.　

The brand comprehensively embodies the company's design, product quality, operation management and after-sales service level. This requires mold companies to have high learning capabilities and sufficient technical and management personnel. The daily capital management capabilities of the company are proposed Higher requirements. Its design, development and manufacturing require a large number of experienced design technicians and industrial workers.01mm and above, and the foreign high has reached the sub-micron level. Technical and technological barriers 　　

precision Plastic Infusion Apparatus Parts Suppliers are used to produce high-precision plastic parts, and they are also the embodiment of high-precision products. As the basis of precision manufacturing, plastic molds are directly related to the production quality and product performance of related plastic parts. In addition, the long admission review cycle, strict product certification and continuous review system have all formed obvious barriers to new entrants. In recent years, the renewal cycle of industries such as automobiles and home appliances has been significantly accelerated

The standard parts parameter database mainly stores

The naming of the key dimension parameters in the template file is completely consistent with the parameter names of the corresponding standard parts in the standard part parameter database, so that parameterized driving can be conveniently carried out. As there are many domestic and foreign standards for cover mold design, when designing a standard part parameter database, various standards are stored in different databases..　　

This design method can significantly improve the efficiency of program query, and it is also conducive to the expansion and maintenance of the database. For each type of standard parts, a corresponding three-dimensional parameterized standard part solid model was established in accordance with commonly used specifications. In addition, according to the nature of the parameters, the parameters are divided into constant parameters, series parameters and continuous parameters that vary within a certain range.The standard parts parameter database mainly stores various parameters of standard parts. At present, the standard parameter database of automobile die issued by Volkswagen,

Ogihara and China Automobile Manufacturers Association has been established. Standard parts are divided into 12 categories such as lifting device, limiting device, side punching device, punching device, positioning device, elastic device, pneumatic device, fastening device, pressing and unloading device, installation device, turning device, guide device, etc. In each database, establish corresponding tables according to the classification of standard parts, and each table stores the serialized parameters of a China Medical Device Mould suppliers type of standard parts.

Typical structural parts are divided into four types: ribs, bosses, lifting lugs, and U-shaped grooves. The parameters of standard parts are divided into key parameters describing main structural features and auxiliary parameters describing secondary features. Through the analysis of commonly used standard parts, the correlation between the primary parameters and the secondary parameters is established.　　 When naming parameters, fully comply with the existing mold design standards to conform to the use habits of designers.

Optimization of the hollow profile mold with double die holes

The symmetrical bridge can now be changed to a partial bridge. Only the length of the working belt is used to adjust the mold holes. 4. If the hindrance is too great, it will also facilitate mold repair. Therefore, the large surface die hole in the welding chamber is pre-adapted Length of the ribs, so that when the metal flows to the die hole, the ribs act like a low wall to hinder the flow of metal.　　5.

Optimization of the hollow profile mold with double die holes that are easy to deviate. Obtaining high-strength and high-quality welds is Packing box mould certainly our ideal. Some profiles have very small openings, almost closed. Under normal circumstances, whether the two die holes are discharged up and down or left and right, the metal flow rate near the center is fast and the material supply is sufficient, so that the upper mold core will move towards Outer elastic deformation causes a thin wall defect of the profile away from the center.　　

For the design of aluminum extrusion die products, with the rapid development of various industries in the society, the cross-sectional shape of the profile has become more complicated and diversified.1.　　3. For this reason, the author designed the mold: the upper mold adopts a partial bridge, and the lower mold is designed with convex ribs in the silo. Generally, due to the fast flow of metal in the large-surface shunt hole, when the shunt bridge is designed as a partial bridge type, this increases the space filled by the material in the large-surface shunt hole to both sides, and follows the center of the shunt bridge If the line deviates outward, the position of the material flow soldering station will also move outward.

When the metal flow fills the mold hole, the metal flow from the feed plate passes through the bridge of the bridge feed plate to block the cantilever without directly acting on it, which reduces the positive pressure on the mold cantilever, thus Improve the stress state of the cantilever. Thus, the production efficiency of profile extrusion is greatly improved and the production cost of the product is reduced. In the production process, defects such as wavy of the large surface of the profile and out-of-tolerance of the plane gap are generally caused by the large surface diversion hole close to the center and the rapid metal flow rate

The precision mold repair has been gradually replaced by laser welding

It can be applied to many metals, especially to solve the welding of some difficult-to-weld metals and dissimilar metals. When working, the power supply assembly is adjusted to a suitable voltage, and the plating pen filled with the plating China Medical Accessories Mould Factory solution is moved at a certain relative speed at the contact part of the surface of the repaired workpiece. Therefore, the cooling channel can be placed close to the mold contour 2~3mm for optimal cooling.

At present, the precision mold repair has been gradually replaced by laser welding. With the numerical control system, the parts with complex shapes and other parts that are difficult to handle by conventional methods can be locally hardened, and different parts of the parts can be hardened by different lasers. Although in the past few years, the structure and system of my country's mold industry have made great changes, mainly in the following: medium and high-end molds, large-scale, precise, complex, and long-life. For example, temperature regulation occurs in high-gloss mirrors (high-gloss effect).

They are mainly manifested in the following aspects: First, the restrictive factors such as mold steel; Second, the standardization level needs to be improved; Third, the high-end mold talents urgently need to be cultivated; Fourth, accelerate the pace of mold product structure adjustment; Fifth, increase investment to strengthen innovation Ability; Sixth, to promote the integration and reorganization of mold companies; Seventh, the development of overseas markets needs to be deepened.　　Laser welding is gradually replacing traditional mold repair technology.

Through cooling, in addition to shortening the production time, it can also reduce the deformation of the parts. In the past few years, the material flow characteristics during the injection molding process were uncontrollable, but now it can be Controllability can be achieved. 　　 Mold expert Luo Baihui said that there are many ways to repair molds, such as electric spark process, argon arc welding repair, laser surfacing technology, and brush plating method. Fa? The mold produced by nacht using this cooling technology can shorten the production time by 40 when used in mass production, which means that the production efficiency of injection molding has been greatly improved. It is not difficult to see that it is not reasonable.

The key to small clearance finishing is to have reliable chip

This can be set by the operator according to the requirements of the workpiece drawing. If the electrode cross-section size is 2mm*20mm, the cavity depth is 100mm, the processing time is 5.The Charmilles machine tool adopts a digital full-closed-loop servo system, which can respond within 2ms, and then make a displacement of 10Ls within 24ms. More importantly, Charmilles' detection methods have been developed into the PILOTEXPERT expert system.5h with copper electrode, the effect is quite good. It is difficult to achieve high speed in such a short time and small stroke.5h with graphite electrode and 8.5g).2s, and the discharge gap of 10 times the height of the lift is enough, that is, it is enough to lift 0.　　

The key to small clearance finishing is to have reliable chip removal, so Charmilles attaches great importance to the development of new lifting technology. This artificial intelligence device can accurately and quickly detect each pulse, classify, count and judge it, cut off the energy pulse and change the pulse parameters, so that the concentrated discharge area is cooled down and the formation of pollution caused by the compensation gap is reduced.

It ends at Injection Syringe Mould Manufacturers the moment when the arc is about to start, and the efficiency is high. In the finishing process, the time to lift the knife is generally only about 0.6mm.　　 The superposition of the two effects is sufficient to effectively control the length of the concentrated discharge pulse train. The gap enlarges the effect, and at the same time gives the servo system a clear micro-lift signal.

At the same time, the lifting speed of the rough machining of small area narrow grooves has been increased twice (close to 3m/min, acceleration 0.4-0. On the contrary, due to the small gap, considerable hydraulic pressure will be formed at the moment of lifting and resuming discharge.. The sooner the pulse train is terminated, the better the flatness, but the efficiency is low. This is exactly the distance required for finishing the first discharge to work stably

You can also use this work belt to calculate the length of the work

Duan, its development Piston mould is in the ascendant, and many calculation formulas can not get rid of the constraints of traditional mathematical formulas, so we should vigorously develop new applicable software, establish a complete database and intelligent system, establish mathematical models with accurate boundary conditions, and solve the extrusion process. The computer database contains a series of data such as straight lines, circles, arcs, etc.

You can also use this work belt to calculate the length of the work belt on all the die holes of the porous die, so that the velocity of the equidistant die holes is kept as consistent as possible. At present, the finite element analysis method is generally used to determine. Because the ratio of the perimeter area of ​​the end of the standing rib is greater than the middle (especially the intersection of the ribs) ) Perimeter area ratio, so the friction force of the working belt at this place is greater than other parts. At this point, the length of the working belt is given, which is almost equal to the wall thickness of the profile. This kind of standing bar should be adjusted according to the end conditions of the standing bar when calculating the length of the working belt. ) = 100mm, the deformation coefficient is 0.004=99. Many The CAD program has this function.

Compared with manual drawing, the computer Drawing can save time 50~80, and the time saving is to modify the existing drawings. The calculation is fast and accurate, and it is easy to modify, regardless of the complexity of the profile. 2CAD/CAM system is more and more widely used in die hole size gauge aluminum alloy profiles, and the requirements for the mold structure and the shape of the die hole are also getting higher and higher due to the complexity of the mold structure and the geometry of the machining route of the CN machine tool.

The following key points Discuss the application of CAD/CAM system in the design of several main structural elements of extrusion die. For example, when extruding a profile of 100mm< 2.5mm, the dish-shaped deflection coefficient is 0. The amount of shrinkage compensation increases steadily with the increase of the size of the profile. The data collected from the mold production can be compared and analyzed. When the wall thickness of the profile is very different, at the intersection of thick and thin walls, the transition zone of the working belt must be designed in all working belts. The software developed can input the geometry of the profile and output the changed geometry of the mold.

It covers the entire mold design process from accepting product

The reverse engineering method is as shown. It saves each The geometric function information of a part. The data obtained is defined as an ibl file. Obtain point cloud data from the measurement results after the above processing, and process it as a characteristic curve according to the vector direction in Pro/Engineer, further generate a snapshot surface and a characteristic surface, and then perform cutting and stitching processing to obtain an accurate and smooth CAD product

The model, as shown. Skilled application of CAD/CAM technology will greatly improve Mold design and manufacturing efficiency to ensure mold accuracy.. At the CAD modeling stage, we must pay attention to the use of feasible means to maintain accuracy.　　It depends on the application of high-performance integrated CAD/CAM software.　　

2CAD/CAM's influence on the finishing of the clamping surface is limited by the direction of the mold. It covers the entire mold design process from accepting product models, drawing part drawings, to compiling bills of materials, and generating processing data. Because these losses are cumulative, you should minimize the number of format conversions when designing the part model, and ensure that the part model tolerance is set sufficiently small during the conversion, at least 10 times smaller than the finishing tolerance. Usually the model generated by directly using these data as the characteristic surface is not flat enough.The design and manufacture of automobile lamp molds, as high-end applications of complex curved surface injection molds, have more and more extensive market demand and higher profits, so they have gradually developed into a specialized industry in China, in Shenzhen, Guangzhou,

Jiangsu and Zhejiang Plastic Infusion Apparatus Parts Manufacturers manufacturers have turned into professional manufacturers of lamp molds. Processing such a large area of ​​the mold clamping surface cannot be solved only at the CAM stage. This kind of problem is usually caused by inconsistent tolerances when the stitched curved surfaces are molded separately. The main professional modules include the application of Scantool, 1Pro/Engineer reverse engineering modeling technology in lamp mold projects The design and production process of automobile molds generally goes through the process of automobile master model, process model, mold design, mold manufacturing, mold quality inspection, and then trial mold and manual modification.

At present, most CAD systems have Provide file interfaces of AP203, AP214 and IGES.　　

There are currently commercial software platforms that can support the implementation of agile manufacturing. Therefore, it is necessary to establish a unified product information description and data exchange standard that supports different application systems. The core layer is used to support the operation of business systems and industry databases; the public layer is used to support network conferences, information publishing, e-mail, FTP, etc. They are typical high-value-added and high-risk products.　　

The system network structure is divided into three levels: core layer, public layer and external layer. It is not limited to one enterprise. This is of great importance to the challenges faced by China after joining the WTO and the current lack of capital, outdated equipment, and weak technical force in China's mold industry at the current stage, to give full play to their respective advantages, coordinate operations, and change the long-term backward situation of China's mold manufacturing Theoretical significance and practical application value. Formulate corresponding application protocols and develop CAD systems based on feature knowledge. This requires the establishment of A mapping mechanism (data interface) from one AP to another AP and a shared database containing the above multiple APs.

The side plate rotates 90 along the center of the hinge pin

The problems encountered by the Guang A continuous pestle mechanism using this mold and the countermeasures 5. The basic principles of connecting rods and hinges are applied to the design of the actual production mold to make the structure of the mold simpler and more convenient to use. (Continued from page 24) The control of the difference stipulates that the hydraulics must measure the temperature difference of each section every 2 hours and make a record. In the past, it has been processed with 1 channel steel.1

Workpiece introduction The board board part mm, the cross-sectional size is 100x40, the total length is 998mm, there are three holes with a hole diameter of 21mm on the symmetry center line of the bottom plate, and the cross-sectional shape is a U-shaped groove. When it is found that the temperature difference changes greatly, adjust the water pressure in each section in time to ensure that the temperature difference is maintained at an appropriate Within range. 3 Conclusions Increasing the iron content of the raw materials into the furnace, reducing the amount of slag, reducing the powder of the furnace, and improving the gas permeability of the furnace material column are the basis for the enhanced smelting of the furnace.8 (f is the wall thickness of the workpiece), and it has the condition of one-time bending.

The side plate rotates 90° along the center of the hinge pin axis under the action of external force, and the blank plate gradually bends, deforms, corrects, and forms under the action of the side plate.2 Process analysis During the bending deformation process, the outer structure of the bending band is subjected to tensile pressure.. By strengthening the management of the cooling stave, the furnace type is maintained and the furnace life is extended.

Due to its poor Medical Accessories Manufacturers, it is easy to deform and the quality is unstable.2 Calculation of the unfolded dimension of the bending part L=i=2L+Left at left=0. Otherwise, the gap between the concave mold and the convex mold is too small, and the blank cannot be pressed or 'stuck' after pressing.Abstract: To analyze the dome-shaped process of the floating plate groove, it is feasible to use mold pressing.1 Bending force. After analysis, it is caused by the insufficient strength of the side plate and the insufficient rigidity of the die

The punching force of materials after we understand the tensile

What is blanking power? Punching force refers to the maximum resistance of the material to the die during punching.

There are many reasons in the work that affect the punching force, but the two main reasons that have a great influence on the punching force are the shear strength and tensile strength of the material. The harder the material, the greater the punching force. I will give you some tensile strength and shear strength of some materials

It is very easy to calculate the punching force of materials after we understand the tensile and shear strength of the materials. Let's take a look at what is said in this picture.

In our actual work, in addition to calculating the punching force, the strength of the punch is also calculated, especially the small punch. Let ’s take a look at the stress of the blade during punching.

According to the above figure, when the σ s is 110kgf / mm, the blade part of the punch may be damaged when the SKD11 punch is about 9000 strokes. In addition, after changing the material to SKH51, the possibility of occurrence increased to about 40,000 strokes. The top material punch can also be used to determine the possibility of breakage. However, due to its small cross-sectional area, breakage occurs around 5000 strokes.

In use, the stress σ applied to the punch is lower than the allowable stress of the material of the punch, and no damage will occur. (Depending on the accuracy of the mold, the structure of the mold, the specification deviation of the processed material, the surface finish of the punch, the heat treatment, and other conditions, please use this figure as a reference standard

Of course, the actual calculation is definitely more complicated than this. After all, it is only a theory. Various factors will cause the result to drift, so it is necessary to grind the punch.
