摘　　要：采用CAE方法对某公司开发的新型蟹笼挂钩产品进行注塑成型分析,设置了合理的工艺参数及质量目标,然后,采用响应面法对玻纤增强PA66工程塑料产品的注塑成型工艺进行多目标回归分析。结果表明,在注塑成型过程中,产品的翘曲及收缩受到多种因素的影响。其中,熔体温度、保压时间及熔体温度与保压时间的交互项3个因素对产品体积收缩率的影响较显著;而熔体温度、注塑时间、熔体温度的平方及注塑时间的平方4个因素对产品翘曲变形量的影响较显著。当模具温度为115℃、熔体温度为310℃、保压时间为12 s、注塑时间为0.98 s时,产品具有最佳目标值,优化后产品的体积收缩率及翘曲量分别为14.34%、0.1925 mm。A new crab cage hook product developed by a company was analyzed based on the CAE platform,and reasonable process parameters and quality objectives were determined;the response surface method was used conduct the multiple objective regression analysis for the injection molding process of glass fiber reinforced PA66 engineering plastic products.The results showed that the warpage and shrinkage of the product were more significantly affected by multiple factors during the injection molding process.The three factors of melt temperature,holding time and the interaction of melt temperature and holding time had a more significant impact on the volume shrinkage of the product;while the four factors of melt temperature,injection time,the square of melt temperature and the square of injection time showed more significant impact on its warpage.When the mold temperature was 115℃,the melt temperature was 310℃,the holding time was 12 s,and the injection time was 0.98 s,the product had the optimal values with its volume shrinkage and warpage 14.34%and 0.1925 mm,respectively.
