What should we pay attention to in plastic mold design?

Plastic mold design is one of the important links in the mold manufacturing process, need to pay attention to the following 5 problems:

1. Material selection

The material choice of plastic mold has a crucial impact on the quality and service life of the mold. According to different application scenarios and requirements, different materials need to be selected. For example, for molds requiring high precision and high surface quality, materials such as stainless steel and advanced alloys can be selected; For the mold requiring wear resistance and corrosion resistance, you can choose cemented carbide, polytetrafluoroethylene and other materials.

2. Structural design

The structural design of plastic mold is one of the key factors to realize the function of the mold. The factors to be considered in the structural design include: the opening and closing mode of the mold, the location and size of the gate, the design of the cooling system, and the way of taking out the product. Structural design needs to be combined with material characteristics, production process and other factors for comprehensive consideration to ensure the quality and service life of the mold.

3, precision design

The precision design of plastic mold has an important impact on the quality and production efficiency of the product. The factors that need to be considered in precision design include: dimensional accuracy of the product, surface quality, shape accuracy, etc. Precision design needs to be combined with material characteristics, production process and other factors for comprehensive consideration to ensure the quality of products and production efficiency.

4, heat treatment and surface treatment

The heat treatment and surface treatment of plastic molds play an important role in improving the quality and service life of the molds. Heat treatment can improve the hardness and wear resistance of the material by changing the internal structure of the material; Surface treatment can improve the corrosion resistance and wear resistance of the mold by changing the shape and properties of the mold surface. Heat treatment and surface treatment need to be comprehensively considered in combination with material characteristics, production process and other factors to ensure the quality and service life of the mold.

5. Maintainability design

Plastic molds may have various problems during use, and need to be repaired and maintained. The factors to be considered in maintainability design include: ease of disassembly and installation of the mold, ease of replacement of parts, etc. The maintainability design needs to be comprehensively considered in combination with the actual production situation to ensure the service life and production efficiency of the mold.

In general, plastic mold design needs to pay attention to material selection, structural design, precision design, heat treatment and surface treatment, and maintainability design. At the same time, it is also necessary to comprehensively consider the actual production situation to ensure the quality and service life of the mold.
