Injection mold belongs to many molds in a wide range of applications, whether in the cosmetics industry or some daily necessities in the processing, are often applied. In the process of mold processing, for the entire production process and related details of the work should be done, otherwise it may lead to the mold is affected.

1, the surface of the injection mold must be smooth

In the production of injection molds, if the mold surface is not smooth enough, will affect the surface finish of subsequent products, but also easy to increase the possibility of plastic products and molds adhere to each other, resulting in a significant reduction in the pass rate of the finished product. Therefore, in the process of mold processing, it is important to make the details of the parts more detailed, for the subsequent production of related products to lay a good foundation.

2, do a good job related to mold design and development work

Injection molded products can change the appearance of many styles, in the production of different types of injection molded products in the process, for the type of mold and the relevant standard requirements will have a relatively large difference. Therefore, before the mold processing, be sure to do a good job with the customer demand details of the communication work, clear mold specific standards and then subsequent production and processing, so that the mold to better meet the subsequent production of injection molded products.

3, do a good job in the mold vent processing work

In the process of mold processing, be sure to pay attention to do a good job of venting holes reserved for the work. If not reserved vent holes, in the subsequent injection of the corresponding melt is easy to produce bubbles, affecting the overall product quality. Do a good job in the design of the mold venting holes, the melt in the air bubbles can be better discharged, improve the quality of injection molding products.

Mold processing industry is developing rapidly, now many things are made of mold processing

1, the mold for processing technology can require high precision, the mold is generally composed of concave mold, convex mold and mold frame system, some may also be more than one piece of collocation design module. So the combination of the upper and lower mold, block and cavity combination, the module function between the collocation are required to have a very high precision processing methods. Mechanical mold dimensional calculations often reach μm level of accuracy.

2, complex shape, some products such as automotive panels, aircraft parts, toys, household appliances, etc., the surface shape is composed of a variety of curved surfaces, so the mold cavity surface is very complex. Some surfaces are handled by mathematical methods.

3, batch small mold production is not mass production, in many cases only a pair of production.

4, process more mold for processing always have to use their own milling, boring, drilling, reaming and tapping threads and many other different processes.

5、Repeat production mold service life.

6, copy processing, mold production sometimes no pattern, no data, should be based on the object of copy processing. This requires high simulation accuracy, no deformation.

7, mold material performance is excellent, high hardness, the main material of the mold is made of alloy steel, especially high life mold. This kind of steel from rough forging, processing to heat treatment have strict requirements. Therefore, the preparation of the processing technology can not be ignored, heat treatment deformation is also a problem that needs to be seriously addressed in the processing.

According to the analysis of the above there are many development characteristics, in the selection of machine tools to be unable to meet the technical requirements of the enterprise processing as far as possible. Such as CNC control system function to be strong, machine tool precision to be high, rigidity should be good, thermal stability should be good, with profiling function and so on.

Injection mold processing needs to have a variety of process requirements, in addition to the provisions of the host, but also need a large number of auxiliary equipment to help complete the various processing procedures, auxiliary equipment, automation, rationalization, perfection, which to a certain extent determines the viability of the product and the enterprise, so the auxiliary equipment in the production of play an important role.

According to the functional division can be divided into three categories of material supply system equipment, edge waste recycling, temperature control system devices, processing also played a different function, material supply system has a drying effect, temperature control, recycling, temperature control can be used in the cooling, and recycling can reduce the enterprise's production costs, the material supply system in the drying, conveying, measuring, mixing steps also played an indispensable role. Drying equipment can absorb moisture-prone materials, pre-treatment of materials before molding, etc., such as plexiglass, polycarbonate, polyformaldehyde and other certain processes to ensure the quality and dryness.

Injection mold processing in the heating equipment mainly used for extrusion, injection molding, calendering, such as barrel molds and calendering rollers temperature heating controller, modern often use thermal oil heating instead of complex steam heating, refrigerator points have air-cooled and water-cooled, air-cooled heat transfer capacity is low, so it is not used in large quantities, and water-cooled heat transfer capacity, heat exchange effect is good and is widely used. We know that the injection mold processing of the edge of the waste accounted for the proportion of the total production volume of 5% to 20% or so, the recycling of the edge of the use of different crushing equipment, such as pipe class longer products available pelletizing crusher equipment, waste silk recycling equipment can be a granulator equipment, and so on.
