[Abstract]:  

This paper was detailed to introduce a design process of pipe frame injection mold. First to analysis original data, including the properties of the material (polypropylene) and technological characteristics of the plastic part, then decide the divide surface of cavity and the arrange way of mold cavity, designing the side take out core outfit and guide runner and slide block, still carried on the calculation towards modeling part, cavity deep and thick, hot up and cooling, at last, check the data of injection molding machine. This design introduces the design process of a middle complexity injection mold, and optimizes and improves the molding design so that to increase the quality of molding design and shorten the design time.
