Injection molding speed , high degree of automation , forming a complex shape , size and precise product advantages , its products are widely used in home appliances, information industry as structural, functional pieces as well as special-purpose precision pieces , car industrial and other fields in . But the prevalence of conventional injection molding product development cycle is long , complicated process parameters , the process is difficult to control the quality and other issues . In response to these issues , this paper, telephone handle the upper and lower shell two non- volume parts such as common-mode structure analysis example , launched a study on the optimization design of injection mold - critical systems and injection molding process parameters Moldflow mold flow analysis software - based MPI platform . Telephone handle the upper and lower shell , for example through the CAD model to establish and meshing , the the grid matching rate and aspect ratio of a reasonable choice , the establishment of effective finite element model for flow analysis and cooling analysis , accurate results for the analysis of provides reliable protection . Use of the moldflow mold flow analysis software , to analyze the best gate location , predict the products may produce defects to be corrected . Simulate a variety of programs , eventually come to a more reasonable gating system and the cooling pipe design . By orthogonal test , combined with the actual production come to the best molding process parameters . Use the CAE simulation techniques can reduce the tryout , the number of repair mode , and to shorten mold design and manufacturing cycles , reduce production costs .
