Abstract: plastic industry is in the world grows now one of quickest industry classes, 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; Finally introduced now in the world the most popular three dimensional CAD/CAM system standard software PRO/ENGNEER''s PROGRAM module, and led the wrap to the guide pillar to carry on the parametrization design.
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.
Key word: The plastic mold;the parametrization; inlays;divides the profile
