Although a lotof plastic forming method, but the main method is to plastic injection forming, the plastic mold market in plastic forming mold production is about half of the injection mould. In recent years, with the rapid development of industry inour country to the mold industry, puts forward higher and higher requirements for plastic mould. Injection molding isa kind of important method of plastic molding, it is mainly suitable for thermoplastic plastic molding, can plicated shape of precision plastic forming parts. As a design model, this topic is to plastic faucet will injection mold related knowledge as the basis, elaborated the design of plastic injection mould process. This design's main task is to study the molding technology of faucet and design the injection mold and its structure is characterized by side gate in the form ofa single parting surface injection mould, with side core-pulling and arc core pulling, and in the subsequent design, solid model is studied by using CAD software for plastic parts, process of plastic parts structure analysis, a clear design ideas, to determine the injection molding process and to each specific parts of detailed calculation and checking, to ensure that
