摘　　要：为提高塑料薄壁零件的注塑成型质量,以汽车轮毂罩为研究对象,按照实际工况,利用Moldflow软件进行模流仿真分析,结合正交实验对轮毂罩的翘曲变形进行对比优化,以最小据翘曲变形量确定最优化的浇注参数,并在此基础上通过UG NX软件对该件的模具型腔进行加工仿真。最终确定的优化工艺参数组合为熔体温度260℃,模具温度85℃,注射时间55 s,保压时间6 s,保压压力90%。此优化数值模拟结果将产品的翘曲变形量优化了16.4%,为同类型产品的工艺改进和模具设计提供了一定参考。In order to improve the quality of injection molding of plastic thin-wall parts,the automobile hubcaps are studied as the object in this paper.According to the actual working conditions,the Moldflow software is used for simulation analysis of the modulor flow;combined with the orthogonal experiments,the warping deformation of the hub cover is compared and optimized;then,the optimal pouring parameters are determined according to the minimum warping deformation.On this basis,the UG NX software is used for the mold cavity processing simulation.The optimal process parameters are as follows:the melt temperature is 260℃,the mold temperature is 85℃,the injection time is 55s,the pressure holding time is 6s,and the pressure holding pressure is 90%.The warping deformation of the product is optimized by 16.4%by the numerical simulation results,which provides a certain reference for the process improvement and die design of the similar products.
