Abstract
China's household electrical appliance industry in the development of high-speed tooling industry,in particular the plastic mould of the ever-increasing demands.In 2004, the plastic mould industry in the entire Die share has risen to 30% According to the experts predict that in the next few years,China plastic mold industry will continue to maintain an average annual growth rate of 10% over the high rate of development.In this paper, the design of the race cars at the end of the wind A fan of the dual-cavity injection mold the entire design process, analysis of plastic parts, injection machine and select the part of the calibration parameters, and then the overall design of injection mold, molding plastic parts, including Machines chosen, the overall design molds、geometry and the size of their parts and components forming part of the design, delivery of pouring molten plastic system design, precision plastic parts from the impact of the row over gas system design, Demoulding body cooling system and the motif (mold) design. This article has three drawings, which are scheduled for the Department of loaded-mode map, the Department of dynamic maps and assembly equipment. Since the plastic parts all around with a groove, so the design of the side core-pulling mechanism to solve this problem is the core.
Key words: Injection plastic mould; Bevel Pillar; Cavity; cooling system
