Mold injection molding is a processing method used in batch production of complex parts of certain shapes. The detailed principle refers to: the plastic raw material that is heated and ablated is pushed by the screw of the injection molding machine into the cavity of the plastic mold, and after cooling and solidifying, the plastic formed product is obtained.
The plastic mold consists of two parts: a movable mold and a fixed mold. The movable mold is mounted on the moving template of the injection molding machine, and the fixed mold is mounted on the fixed template of the injection molding machine. In the case of injection molding, the movable mold and the fixed mold close constitute a casting system and a cavity, and when the mold is opened, the movable mold and the fixed mold are separated to take out the plastic product.
Although the structure of the mold may vary depending on the type and function of the plastic, the shape and structure of the plastic product, and the type of the needle machine, the basic structure is common. The mold is mainly composed of a casting system, a temperature regulation system, a molding part and a structural part. The casting system and the molded part are directly touched with the plastic and change with the plastic and the product. It is the most complicated part of the mold, the biggest change, and the part with the highest processing precision and precision.
Injection molds are tools for producing plastic products; they are also tools for giving plastic products complete structure and accurate dimensions. Injection molding is a processing method used in batch production of complex parts of certain shapes. Specifically, the plastic that is heated and ablated is injected into the cavity by the high pressure of the injection molding machine, and after cooling and solidifying, the molded article is obtained.
