摘　　要：深腔类塑件的模具大多具有细长、悬臂式的型芯,在注塑成型过程中,型芯由于受到聚合物熔体的不均匀压力易产生偏移,造成制件出现厚度不均等多种缺陷,严重影响制件的成型质量,降低生产效率,因此型芯偏移的优化问题亟待解决。对近年来国内外学者优化型芯偏移量所采用的方法进行介绍,并探讨了型芯偏移优化今后的发展趋势。The mould for deep cavity plastic parts had slender and cantilevered cores.The cores were prone to drift due to the uneven pressure of the polymer melt in the injection molding process,resulting in uneven thickness of the parts.This seriously affected the molding quality of the parts and reduced production efficiency.Therefore,the optimization problem of core shift was needed to be solved urgently.The methods of core shift optimization adopted by domestic and foreign scholars were introduced in recent years,and the development trend of core shift optimization in the future was discussed.
