Principle of Injection Mould

  • Injection mold is a tool for producing plastic products; it is also a tool for giving plastic products a complete structure and precise dimensions.

    Mold injection molding is a processing method used in the mass production of some complex-shaped parts. The specific principle is: the plastic raw material melted by heat is injected into the cavity of the plastic mold by the screw of the injection molding machine at high pressure, and after cooling and solidification, a 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 products.

    Although the structure of the mold may vary widely 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 the same. The mold is mainly composed of a pouring system, a temperature control system, forming parts and structural parts. Among them, the pouring system and the 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 complex and the most variable parts in the plastic mold, requiring the highest processing finish and precision.

In order to reduce the heavy workload of mold design and manufacturing, most of the injection molds use standard mold bases.
