Injection molding is a kind of important method of plastic molding, it is mainly suitable for thermoplastic plastic molding, can be a complicated shape of precision plastic forming parts. In recent years, with the rapid development of industry in our country to the mold industry, puts forward higher and higher requirements for plastic mould. Project design, first of all, analyzed the technological characteristics of plastics article of faucet, using CAD software for plastic parts entity model, process of plastic parts structure analysis. The faucet of the structure of injection mould design is the side gate in the form of a single parting surface injection mould, with side core-pulling and arc core pulling. And in the subsequent design process gradually clear the design idea, determine the injection molding process and to each specific part carried on the detailed calculation and checking, to ensure that the structure are designed, which can ensure the mold work using reliable, ensure the communicate and coordinate with other parts of the final use AutoCAD draw a set of mold assembly drawing and part drawing.
