摘　　要：针对塑料注射成型中产生的型芯偏移,结合材料的粘度图研究了工艺参数对填充阶段型芯偏移的影响。结果表明:熔体温度对型芯偏移的影响最大,其次是注射时间,而模具温度的影响很小;提高熔体温度与缩短注射时间可以降低熔体粘度,降低注射压力,从而减小型芯偏移。The effect of processing parameters on the core shift was investigated in the filling stage of plastics injection molding,combined with the viscosity plot of the material.The results reveals that melt temperature has the greatest effect on the core shift,followed by injection time,while mold temperature hardly influences the core shift.Increasing melt temperature and shortening injection time lowers the melt viscosity,and reduces the injection pressure,thus minimizes the core shift.
