Precision Plastic Injection Mold
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 a cavity. When the mold is opened, the movable mold and the fixed mold are separated to take out the plastic products.
Features
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 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. Injection mold is a tool for producing plastic products; it is also a tool for giving plastic products a complete structure and precise dimensions. Injection molding is a processing method used in the mass production of some complex-shaped parts. Specifically, it refers to the high-pressure injection of the plastic melted by heat into the mold cavity by the injection molding machine, and the molded product is obtained after cooling and solidification.

During injection molding, the movable mold and the fixed mold are closed to form a pouring system and a cavity. When the mold is opened, the movable mold and the fixed mold are separated to take out the plastic products. In order to reduce the heavy workload of mold design and manufacturing, most of the injection molds use standard mold bases.
When the single parting surface injection mold is opened, the movable mold and the fixed mold are separated to take out the plastic part, which is called a single parting surface mold, also called a double-plate mold. It is the simplest and most basic form of injection molds. It can be designed as a single-cavity injection mold or a multi-cavity injection mold according to needs. It is the most widely used injection mold.Advantage
Double parting surface injection mold The double parting surface injection mold has two parting surfaces. Compared with the single parting surface injection mold, the double parting surface injection mold adds an intermediate plate that can be moved locally in the fixed part of the mold. It is called a movable gate plate, which is equipped with gates, runners and other parts and components required by the fixed mold), so it is also called a three-plate (moving plate, intermediate plate, fixed plate) injection mold, which is often used for point casting For single-cavity or multi-cavity injection molds with inlet materials, when the mold is opened, the intermediate plate is separated from the fixed template at a fixed distance on the guide post of the fixed mold, so that the casting system condensate can be taken out between the two templates. The double parting surface injection mold has complex structure, high manufacturing cost, and difficult parts processing. Generally, it is not used for the molding of large or super large plastic products.
