What is the work content of injection mold design?
Injection mold design is a crucial part of the injection molding production process, and its work mainly includes the following 8 aspects:
(1) Product analysis: First of all, the injection mold designer needs to conduct a detailed analysis of the product. This includes understanding the size, shape, material, production requirements, etc., in order to determine the mold design program.
(2) Mold structure design: According to the product analysis results, injection mold designers need to design a mold structure that can produce qualified products. This needs to consider the manufacturing process of the mold, the use of equipment, production efficiency and other factors to ensure the stability, reliability and efficiency of the mold.
(3) The parting surface is determined: the parting surface is the surface where the two parts contact when the mold is opened. Injection mold designers need to determine a reasonable parting surface according to the product structure and mold structure in order to facilitate the manufacture and maintenance of the mold.
(4) Pouring system design: The pouring system is a channel through which the plastic melt is injected into the mold cavity by the injection molding machine. Injection mold designers need to design a reasonable pouring system to ensure that the plastic can be successfully filled in the cavity, to avoid insufficient filling, porosity and other problems.
(5) Cooling system design: The cooling system is used to cool and solidify the plastic in the mold. Injection mold designers need to design an effective cooling system to ensure that the plastic can be adequately cooled to avoid shrinkage, deformation and other problems.
(6) Ejector system design: ejector system is used to ejector molded products from the mold. Injection mold designers need to design a reasonable ejector system according to the shape, size, material and other factors of the product to ensure that the product can be successfully ejector and avoid the problem of too large or too small ejector force.
(7) Exhaust system design: The exhaust system is used to discharge the gas in the mold to avoid problems such as pores during injection molding. Injection mold designers need to design an effective exhaust system to ensure that the gas can be smoothly discharged.
(8) Mold trial and adjustment: After the completion of mold design, it is necessary to carry out mold trial production to check whether the mold design meets the production requirements. If a problem is found, the mold needs to be adjusted and optimized until the production requirements are met.
In general, injection mold design is a complex and meticulous process that requires a comprehensive consideration of multiple factors to ensure that the mold can produce qualified products. At the same time, injection mold designers also need to constantly learn and update knowledge to adapt to changing market demands and technological developments.
