Although the structure of plastic injection mold may be kaleidoscopic due to different types and properties of plastics, shapes and structures of plastic products and types of injection machines, 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 casting system and molding parts are the parts in direct contact with plastics, and change with plastics and products. It is the most complex part in the plastic mold, with the biggest change and the highest processing finish and precision required.
Plastic injection mold is composed of moving mold and fixed mold. The moving mold is installed on the moving mold of the injection molding machine and the fixed mold is installed on the fixed mold of the injection molding machine.During injection molding, the moving mold and the fixed mold are closed to form the casting system and cavity, and the moving mold and the fixed mold are separated to take out the plastic products.In order to reduce the heavy work of mold design and manufacture, the plastic injection mold mostly adopts the standard mold frame.
Plastic injection mold is one of the important technology and equipment, production of various industrial products with the rapid development of plastic industry, as well as plastic products in aviation, aerospace, electronics, machinery, shipbuilding and automobile industries, products is becoming more and more high to the requirement of the mould, the traditional mould design method has been unable to adapt to today's requirements. Compared with the traditional mould design, computer aided engineering (CAE) technology both in terms of improve productivity, ensure the quality of products, or in terms of reduce cost, reduce labor intensity, has great superiority.
