Mold manufacturing in the increasingly high status and die level of technology, has become a national manufacturing measure the level of the important signs. With the development of the plastic industry, the plastic injecting mold has already becomeone of the mainly ways of making the plastic ware. This paper mainly introduces the method and the process of the injecting mold designing. First, It has introduced the position and function in the developing society of the plastic injecting mold’s making and designing, and analysied the structure of the plastic product,and alsomodified someparts of the structure.Next, this paper introduce the concrete process ofthe plastic mol
-d’s designing. According to the actual designing plastic, carried on the analysis and modifications of the plastic product’s structure craft, the next chapter introduced the concrete design process of the plastic injecting mold.The injecting machinewas chosen
according to the product’s weight,the face was chosen according to the structure of
the plastics and model the type of cent of the craft、taking out the organiation of cor-e and the outing organizations、noting system、cooling system and resetting the system to carry on the detailed design towards modeling zero parts and sprinklingat the sa-me time.In addition,returning to design of plastics injected other zero parts ofmold to carry on the simple design, the insight was elaborating in the end of the paper, and the later designing way of the injecting mold was put forward my views and viewpoi
