The general plastic 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. In injection molding, the moving mold and the fixed mold are closed to form the gating system and cavity. When the mold is opened, the movable mold and the fixed mold are separated to take out the plastic products.
Although the structure of the mold may vary due to the variety and performance of plastics, the shape and structure of plastic products and the type of injection machine, the basic structure is consistent. The mold is mainly composed of gating system, temperature regulating system, forming parts and structural parts. The gating system and molding parts are the parts that directly contact with the plastics and change with the plastics and products. They are the most complicated and most changeable parts in the plastic mold, which require the highest machining finish and precision.
