Injection mold is an indispensable equipment for the production of injection molded products. It is a process by which molten plastic is injected into a metal mold. The manufacturing of injection moulds is directly related to the quality of injection moulds, so the manufacturing process of injection moulds must be very precise.
The manufacturing of injection molds needs to be considered from many aspects, including material selection, design and production, processing technology and mold testing. Different injection moulds are suitable for different injection moulds, so it is also necessary to consider the characteristics of injection moulds and production needs when selecting injection moulds.
Material selection is the basis of injection mold manufacturing, commonly used materials are metal and plastic. Metal materials such as steel, aluminum alloy, etc., with high strength, high hardness and other advantages, suitable for large models, high output injection molds; Plastic materials such as nylon, ABS and so on have high wear resistance and toughness, suitable for small models, small and medium-sized batch injection molds.
The design and production of injection mold is based on the selection of materials, and the design of injection mold should take into account the structure of the mold and the difficulty of production. In terms of mold structure, the requirements of injection molding need to be taken into account, and the structure of the mold should be simplified as far as possible to improve the efficiency and output of mold processing. In terms of production difficulty, it is necessary to take into account the processing difficulty of the mold to reduce the production difficulty and cost.
Processing technology is the core of injection mold production, injection mold precision and processing costs are directly subject to the level of processing technology. Machining technology mainly includes CNC machining, wire cutting, electric discharge and so on. CNC machining using computer-controlled CNC machine tools for processing, processing speed, high precision; Wire cutting is the use of wire cutting, suitable for more complex curves; The EDM is processed by electronic discharge, which is suitable for metal processing with high hardness.
The test mold is the key link of the production of injection mold, through the test mold can check the qualified degree of the mold and the molding effect of the injection product. In the test mold, it is necessary to pay attention to the following aspects: injection molding temperature, injection molding pressure, injection molding speed and other factors. The test mold needs to be tested repeatedly until the satisfactory result is achieved.
In short, the production of injection molds needs to take into account many aspects of factors, only through accurate material selection, reasonable design and production, efficient processing technology and strict mold testing process, in order to produce high-quality injection molds, so as to produce high-quality injection products.
