Mold injection molding is a processing method used in mass production of some complex-shaped parts. The specific principle refers to: the plastic raw materials melted by heat are pushed by the screw of the injection molding machine into the cavity of the plastic mold under high pressure, and after cooling and solidification, the plastic molded product is obtained.

The plastic mold is composed of a movable mold and a fixed mold. The movable mold is installed on the movable 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 movable mold and the fixed mold are closed to form a pouring system and cavity. 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 plastic mold may vary widely due to the variety and performance of the plastic, the shape and structure of the plastic product, and the type of the injection machine, the basic structure is the same.

1. The structure of plastic mold is divided by function

Mainly composed of: pouring system, temperature control system, forming parts system, exhaust system, guide system, ejection system, etc. Among them, the pouring system and molded parts are the parts that are in direct contact with the plastic, and change with the plastic and the product. They are the most complicated parts of the plastic mold with great changes and require high processing finish and precision.

1. Gating system: refers to the runner part before the plastic enters the cavity from the nozzle, including the main runner, cold slug, runner and gate, etc.
