EspañolAccording to the different molding materials, there are different hardware molds, injection molds, and special molds. Hardware molds are divided into: including stamping molds (mainly Automotive Mold), forging molds, extrusion molds, extrusion molds, die-casting molds, forging molds, etc.; non-metallic molds are divided into plastic molds, inorganic non-metallic molds, sand molds, and vacuum Molds, paraffin molds, etc. Among them, with the rapid development of polymer plastics, plastic molds are closely related to people's lives. Plastic molds can generally be divided into injection molds, extrusion molding molds, gas-assisted molding molds, and so on.
The requirements for mold design and production are: accurate size, smooth surface; reasonable structure, high production efficiency, easy to automate; easy manufacturing, high life, low cost; design meets the needs of the process, economical and reasonable.
The mold structure design and parameter selection must consider factors such as rigidity, guidance, unloading mechanism, positioning method, and gap size. The wearing parts on the mold should be easy to replace. For Plastic Injection Mold and die-casting molds, it is also necessary to consider a reasonable pouring system, molten plastic or metal flow state, and the position and direction of entering the cavity. In order to improve productivity and reduce the loss of runner pouring, a multi-cavity mold can be used, and multiple identical or different products can be completed in one mold at the same time. High-efficiency, high-precision, and long-life molds should be used in mass production.
