ABSTRACT
Abstract Now The plastics industry in one of the growing quickest industry classes in the world, but the injection mole is develops the quick type .Therefore,There have biggist significance to research injection mold to understood that the plastic of production processimprove the product quality . This desin introduced the basic principle of infection molding,specially single is divided the profile to infect moles structurethe principle of work, That proposes the basic design principle of products; Introduched the details of the system that are cold folw channel infection of mold gating 、the temperature control systemthe design process of going against system ,has given the explanation to the mold intensity repuest; Through this design,may to cast the mold to have a preliminary understanding,motes some certain detail questions in design,understands the mold structurethe principle of working.
