This paper presents plastic industry is grows now one of quickest industry classes in the world, but casts the mold is development quick type, therefore, the research casts the mold to understand the plastic product the production process and improves the product quality to have the very big significance.
This design introduced the injection takes shape the basic principle, specially single is divided the profile to inject the mold the structure and the principle of work, to cast the product to propose the basic principle of design; Introduced in detail the cold flow channel injection evil spirit mold pours the system, the temperature control system and goes against the system the design process, and has given the explanation to the mold intensity request. Design shaped parts，reasonable drawing mechanism and so on．
The design should be certification．Primarily related to the injection machine of important parameters for the certification including die close thickness sizes，the name distance，injection machine of the die draw force and so on．After Qualified in check，the molding parts machining process design must ensure that the quality of Supervision taking into account the economy．
Final assembly is part of the mold，which including the design of assembly steps，
clear proceeding required attention．
Through this design, may to cast the mold to have a preliminary understanding, notes in the design certain detail question, understands the mold structure and the principle of work; Through to the PROGRAM study, may establish the simple components the components storehouse, thus effective enhancement working efficiency.
Keywords: Manufacture process Injection mold Shaped parts The plastic mold Divides the profile
