Mold injection molding is a processing method used in mass production of some complex-shaped parts. The detailed principle refers to: the heated and melted plastic material is injected into the cavity of the plastic mold by the screw of the injection molding machine at a high pressure, and after cooling and solidification, a plastic molded product is obtained.
The plastic mold is composed of two parts: 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 mold may vary depending on the type and function of the plastic, the shape and structure of the plastic product, and the type of injection machine, the basic structure is the same. The mold is mainly composed of pouring system, temperature control system, molding parts and structural parts. In the meantime, the pouring system and the molded parts are the parts that directly touch the plastic and change with the plastic and the product. They are the most complicated and the most changed parts in the mold, requiring the highest processing finish and precision.
Injection mold is a tool for producing plastic products; it is also a tool for giving plastic products a complete structure and accurate dimensions. Injection molding is a processing method used in mass production of some complex-shaped parts. In detail, it refers to the high-pressure injection of the heated and melted plastic into the mold cavity by the injection molding machine, and the molded product is obtained after cooling and solidification.
