摘　　要：夹芯注射成型的工艺参数影响着最终塑件的层间界面前沿位置。实验分别以聚苯乙烯(PS)、高密度聚乙烯(HDPE)为夹芯注射成型的壳层物料、芯层物料,基于正交实验法分析不同工艺参数对夹芯注射成型层间界面前沿位置的影响情况,并获取最优工艺参数组合。研究表明,对于本实验指标而言,其最优工艺参数组合为:PS注射温度255℃、注射速率60 cm^3·s^-1,HDPE注射温度215℃、注射速率60 cm^3·s^-1;基于正交实验法,可以快速而恰当的调整夹芯注射成型工艺参数,达到最优实验结果。The process parameters of sandwich injection molding affected the position of the interlayer interface front of the final plastic part.Polystyrene(PS)and high density polyethylene(HDPE)were used as shell materials and core materials respectively.Based on orthogonal experiment method,the influence of different process parameters on the interface front position of sandwich injection molding was analyzed,and the optimal combination of process parameters was obtained.The results show that the optimal process parameters are as follows:injection temperature of PS is 255℃and injection rate is 60 cm^3·s^-1,injection temperature of HDPE is 215℃and injection rate is 60 cm^3·s^-1;based on the orthogonal experiment method,the process parameters of sandwich injection molding can be adjusted quickly and appropriately to achieve the optimal experimental results.
