Plastics industry is an emerging industry. Since a few decades after the advent of plastic , because of its abundant raw materials , low cost and easy to produce , the plastics industry has developed rapidly, in some ways it has been replaced by a variety of non-ferrous metals , ferrous metals, cement , rubber, leather, ceramics , wood and glass , various industrial sectors become an indispensable material . Therefore, the study about the manufacturing process of injection molding of plastic products and improve the quality of a lot of sense . Through the analysis of this paper Yuba mask geometry , study . First, determine the material of plastic parts , followed by the shape of the plastic parts according to the structure of the parting surface and pouring system was OK. Through the mold design argument to determine the layout, forming part of the structure of the cavity , the guide positioning mechanism , the introduction of the relevant parameters of the mechanism , considering the cavity layout of plastic parts , sub- type structure , thickness requirements , the size of plastic parts , cooling channel layout and many other factors to select the appropriate standard mold , the last of molding equipment was checked . Keywords : parting surface , gating system , cooling system , a variety of checking, molding equipment. 目
