The working principle of precision export two-color mold

2021-04-08

Precision export two-color moldIt is a tool for producing plastic products; it is also a tool for giving plastic products a complete structure and precise dimensions.Precision export two-color moldIt is a part that gives plastic shape and size during molding. 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.

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. 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 plastic is heated and melted in the heating cylinder at the bottom of the injection machine, and then driven by the screw or plunger of the injection machine, it enters the mold cavity through the injection machine nozzle and the casting system of the mold. The plastic is cooled and hardened to form, and the product is demolded. Its structure is usually composed of molding parts, pouring system, guide parts, push-out mechanism, temperature control system, exhaust system, support parts and other parts. Manufacturing materials usually use plastic mold steel modules, and the commonly used materials are mainly carbon structural steel, carbon tool steel, alloy tool steel, high-speed steel, etc. The injection molding processing method is usually only suitable for the production of thermoplastic products. The plastic products produced by the injection molding process are very wide. From daily necessities to various complex machinery, electrical appliances, and transportation parts, they are all molded by injection molds. It is the most widely used processing method in the production of plastic products.

Today, Ruiqingxuan shared the working principle of precision export two-color molds.
