摘　　要：采用Pro/E软件建立了轴承端盖的三维模型,利用Moldflow优化了不同数目浇口位置的浇注方案,对比了三种不同浇注设计方案的注塑性能,优化了轴承盖注塑参数。仿真结果表明:单浇口位置优化的最佳浇注口为轴承端盖中心位置,而双浇口位置优化的最佳浇注口位于轴承端盖的两侧,处于大圆盘结构和小圆环结构的连接位置。三种不同浇注方案的对比可知,最佳浇注方案为调整最优双浇口位置于圆环外侧的浇注方案二。通过对轴承端盖的翘曲变形进行优化设计得到,轴承端盖最优注塑参数为熔体温度200℃、充填时间8 s、充填压力64%,优化后的翘曲变形最大为0.9000 mm,相对于优化之前减小了0.0438 mm,降低4.6%,显著提高了轴承端盖的注塑性能。The three-dimensional model of the bearing end cover was established by Pro/E software,and the pouring schemes with different numbers of gate positions were optimized by Moldflow,the plastic injection performance of three different pouring design schemes were compared,and the injection parameters were optimized.The simulation results show that the best pouring port optimized for single gate position is the center position of the bearing end cover,while the best pouring port optimized for double gate position is located on both sides of the bearing end cover,at the connecting position of the large disk structure and the small ring structure.The comparison of the three different pouring schemes shows that the best pouring scheme is the second pouring scheme that adjusts the optimal double gate position on the outside of the ring.By optimizing the design of the warpage deformation of the bearing end cover,the optimal injection parameters of the bearing end cover are melt temperature 200℃,filling time 8 s,filling pressure 64%,and the maximum warpage deformation after optimization is 0.9000 mm,relative to before optimization,it is reduced by 0.0438 mm,with a reduction of 4.6%,which significantly improvs the injection performance of the bearing end cover.
