摘　　要：运用模拟分析软件Moldflow对某汽车安全气囊盖浇注浇口位置及数目进行模拟优化,综合分析各种因素对注塑成型的影响,确定最佳浇口位置和浇口数目,优化模具浇口设计,能够提前预测可能出现的质量问题,缩短模具设计周期和产品开发周期,提高开发成功率及制品质量。对类似造型的气囊盖浇口的确定提供参考。Based on a simulation software Moldflow, Airbag Cover injection gate location and number is simulated and optimized, and various factors on the impact of injection molding is compre hensively analyzed to determine the best gate location and gate number. Optimization of mold gate de sign can predict the possible quality problems in advance, shorten mold design cycle and product de- velopment cycle, improve the success rate and quality of the product development. Reference is pro vided to the gate determination of similar shape of the airbag cover.
