What Are The Two Parts Of The Plastic Mold?

Mold injection molding is a processing method used in mass production of complex parts of certain shapes. The specific principle refers to: the plastic raw material that is heated and melted is pushed by the screw of the injection molding machine into the cavity of the plastic mold, and after being cooled and solidified, 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 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 performance of the plastic, the shape and structure of the plastic product, and the type of the injection machine, the basic structure is uniform. The mold is mainly composed of a gating system, a temperature control system, a molded part and a structural part. The gating system and the molded part are in direct contact with the plastic and vary with the plastic and the product. It is the most complicated and most varied part of the mold, and requires the highest degree of smoothness and precision.


Injection molds are a tool for producing plastic products; they are also tools that give plastic products complete structure and precise dimensions. Injection molding is a processing method used in mass production of complex parts of certain shapes. Specifically, the plastic melted by the heat is injected into the cavity by the high pressure of the injection molding machine, and after solidification by cooling, a molded article is obtained.
