With the needs of modern industrial development, the plastic becomes one of the main industrial structure materials. Plastic Injection Mould becomes an important processing equipment. This paper introduces the important process of the whole structural design, First, it introduces the development of Plastic Injection Mould, and also its development trend. It analysises the structural shape of the parts, and chose the Plastic Injection Machine. Then, it highlights the concrete design process of the mould. The content includes: the design of products, the design of the running system, the design of the exhaust system, the design of the degating system, the design of the lteral type and pulling mechanism, the design of the cooling system and the parts in the Plastic Injection Mould. At last, This paper summarizes the whole design process.
