In accordance with the different molding methods, can be divided into corresponding to the different process requirements of the plastic processing mold types, mainly injection molding molds, extrusion molding molds, suction molding molds, molding molds, high foam polystyrene molding molds and so on.
Plastic molds, plastic processing industry and plastic molding machine supporting, give plastic products to the complete configuration and precise size of the tool. As a result of plastic varieties and processing methods, plastic molding machines and plastic products and the structure of the complexity of the different, so, the types of plastic molds and the structure is also a variety of different.
The working conditions of plastic mold
As a result of the development of plastics and plastic molding industry, the quality requirements of the mold of plastics are also higher and higher, thus the failure of plastic mold and its influencing factors has become an important research topic. The main working parts of plastic molds are molding parts, such as convex mold, concave mold, etc., which constitute the cavity of the plastic mold to mold the various surfaces of plastic parts and direct contact with the plastic, under pressure, temperature, friction and corrosion and other effects.
Our daily production, life in the use of a variety of tools and products, as large as the base of the machine tool, the body shell, as small as an embryo head screws, buttons, and a variety of household appliances shell, all have a close relationship with the mold. The shape of the mold determines the shape of these products, mold processing quality and precision also determines the quality of these products.
Because of the material of various products, appearance, specifications and different uses, the mold is divided into a casting mold, forging mold, die-casting mold, stamping mold and other non-plastic molds, as well as plastic molds.
