The mold used for plastic injection molding becomes an injection mold, and the injection mold can mold plastic products with complex shapes, precise dimensions, or with inserts at one time. Injection mold is a tool for producing plastic products; it is also a tool for giving plastic products a complete structure and precise dimensions. Its essence is to inject the plastic melted by heat into the mold cavity at high pressure by the injection molding machine, and after cooling and solidification, the molded product is obtained.
Injection molds are divided into thermosetting plastic molds and thermoplastic plastic molds according to the molding characteristics; according to the molding process, they are divided into transfer molds, blow molds, casting molds, thermoforming molds, hot press molds (compression molds), injection molds, etc. , Among them, the hot press mold can be divided into three types: overflow, semi-overflow, and non-overflow. The injection mold can be divided into two types: cold runner mold and hot runner mold based on the pouring system; It can be divided into two types: mobile type and fixed type. According to the molding materials, it can be divided into metal molds and non-metal molds: according to the production volume, it is divided into sample molds (simple molds) and mass production molds.
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.
The injection 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.
