the printer injection mold design process

The mold as industrial products used in the production technology and equipment, play an increasingly significant role in the scale of modern industrial production. Through the mold, the production has a distinctive feature of high quality, efficient, energy saving, low cost, and therefore widely used in the production of automobiles, machinery, electronics, light industry, household appliances, communications, military and aerospace field. In recent years, plastic mold production and level of development is very rapid, efficient, automated, large-scale, long life, precision molds in the mold production, the proportion increasing. Injection mold plastic before adding in the heated barrel of the injection molding machine, the heat melted plastic in the injection molding machine screw or a piston driven by the nozzle and the mold gating system into the mold cavity, the plastic in which curing, the final plastic products.      This paper describes the cover of the printer injection mold design process. Including the structural analysis of plastic parts and material selection, preparation of the mold structure, Moldflow mold flow analysis, the choice of models of the injection molding machine, hot runner gating system design, the design of molded parts, mold to determine the selection of standard parts, mold-oriented institutions to determine the design of cooling systems, the demoulding introduced institutions, exhaust system design, the final check of injection machine. In the design process, using Moldflow software to plastic parts, mold flow analysis, in order to determine the optimal gate location and filling process analysis, on the basis of the analysis of the data and to optimize and improve the mold design to improve the quality of the mold design, shorten design time.   Keywords:  injection mold design; injection molding; Moldflow mold flow analysis; hot runner gating system
