The plastic injection mold design of the plastic valve body
[Abstract] Now the plastics industry is one of the growing quickest industry classes in the world, but the injection mold is develops the quick type. Therefore, there have biggest significance to research injection mold to understand that the plastic of production process and improve the product quality.
This design introduced the basic principle of injection molding, specially double is divided the profile to inject molds structure and the principle of work, That proposes the basic design principle of products; Introduced the details of the system that are cold flow channel injection of mold gating、the temperature control system and the design process of going against system, and has given the explanation to the mold intensity request; The main structure of the injection mould for the difference valve of the cold and hot water machine was introduced according to the structure characteristics of the valve. The mould structure solved the problem of pulling the outer. Threaded side core and the cores for the small holes of the plastic part at four directions. And the solution to the eccentric problem of the feeding system of the mould was explained. Through this design, May to cast the mold to have a preliminary understanding, notes some certain detail questions in design, understands the mold structure and the principle of working.
