Although the structure of the mould may vary widely due to the variety and properties of plastics, the shape and structure of plastic products, and the type of injection machine, the basic structure is the same.The mould is mainly composed of pouring system, temperature regulating system, forming parts and structural parts.Among them, the pouring system and molding parts are the parts directly in contact with plastics, and change with plastics and products, which are the most complex, the biggest changes, requiring the highest processing smoothness and precision.

     The injection mold is composed of moving mold and fixed mold. The moving mold is installed on the moving template of the injection molding machine, and the fixed mold is installed on the fixed template of the injection molding machine.During injection molding, the moving mold and the fixing mold close to form the pouring system and mold cavity. During mold opening, the moving mold and the fixing mold are separated to take out the plastic products.In order to reduce the heavy workload of mold design and manufacturing, most injection mold adopts standard die frame.
