Hello everyone! Today, the editor will tell you a technical training course for a plastic mold processing enterprise in Shenzhen. I hope everyone has a little preliminary understanding of mold. According to functions, plastic molds are mainly composed of: pouring system, temperature control system, molding 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 complex and the most variable parts in the plastic mold, requiring the highest processing finish and precision.


1. Pouring system:


It refers to the part of the runner before the plastic enters the cavity from the nozzle, including the main runner, cold material cavity, runner and gate, etc.

2. Forming parts system:


It refers to the combination of various parts that constitute the shape of the product, including the movable mold, the fixed mold and the cavity (concave mold), the core (convex mold), and the forming rod. The core forms the inner surface of the product, and the cavity (concave mold) forms the outer surface shape of the product. After the mold is closed, the core and the cavity constitute the cavity of the mold. According to process and manufacturing requirements, sometimes the core and die are combined by several pieces, and sometimes they are made as a whole, and inserts are only used in the parts that are easy to damage and difficult to process.
