What are the difficulties of injection mold design?

Injection mold design is a highly technical job that involves knowledge and skills in multiple fields. In injection mold design, there are some difficulties and challenges, the following are some of them:

(1) Determination of the mold structure: the structural design of the injection mold is the basis of the entire design work. The determination of the mold structure needs to consider the shape, size, material, production batch, production process requirements and other factors. At the same time, it is also necessary to consider the processing and manufacturing of molds, maintenance and other factors. Therefore, it is difficult to determine a reasonable and stable mold structure that requires comprehensive consideration of many factors.

(2) Material selection and heat treatment: material selection and heat treatment of injection mold is also one of the difficulties of design. Different plastic materials have different requirements for mold materials, and the choice of mold materials also needs to consider the service life of the mold, processing costs and other factors. In addition, the heat treatment of the mold is also an important link, and the improper selection of the heat treatment process and parameters will affect the hardness, wear resistance and other properties of the mold.

(3) The design of the pouring system: The pouring system of the injection mold is a key part of injection molding, and it is also one of the difficulties of the design. The design of pouring system needs to consider the structural characteristics of plastic products, material characteristics, production technology and other factors. At the same time, it is also necessary to consider the flow balance, exhaust, stability and other factors of the pouring system to ensure the smooth progress of injection molding.

(4) The design of molded parts: The molded part of the injection mold is the part that is directly in contact with the plastic, and its design directly affects the shape and dimensional accuracy of the plastic product. The design of molded parts needs to consider the structural characteristics of plastic products, material characteristics, mold structure and other factors. At the same time, it is also necessary to consider the wear resistance and corrosion resistance of the molded parts to ensure the service life of the mold.

(5) Cooling system design: The cooling system of injection mold is an important part of ensuring mold temperature control, and its design is also one of the difficulties. The design of the cooling system needs to consider the structural characteristics of the mold, material characteristics, production technology and other factors. At the same time, it is also necessary to consider factors such as the heat dissipation effect and uniformity of the cooling system to ensure stable temperature control and high production efficiency of the mold.

(6) Repair and maintenance: The injection mold needs to be repaired and maintained during use to ensure its normal operation and service life. Repair and maintenance need to consider many aspects, such as mold wear, failure, frequency of use, etc. At the same time, it is also necessary to develop corresponding maintenance plans and measures to ensure the normal operation and service life of the mold.

To sum up, injection mold design is a highly technical job that involves knowledge and skills in multiple fields. There are some difficulties and challenges in the design of injection mold, which need to consider several factors comprehensively. At the same time, it is also necessary to constantly carry out technological innovation and improvement to adapt to the changing market demand and production process requirements.
