摘　　要：以汽车双色车灯装饰条注塑件为例,在裂纹风险位置点设置镶块,运用Moldflow-ABAQUS耦合的方法,采用全分体方案和部分拆分方案对镶块进行试验分析,同时完成注塑和结构的一射和二射应力分布云图和应变分布云图。模拟结果表明:型腔最大等效应力为515 MPa,最大变形为0.15 mm,符合车灯模具强度和刚度要求。该方法能够较为全面地反映车灯注塑模具在注塑成型过程中型腔的受力和变形情况,能为同类模具的开发提供有效技术支持。Taking the injection molded parts of automobile dual color light decorative strips produced by the enterprise as an example,setting inserts at the crack risk location,adopting full split scheme and partial split scheme Moldflow-ABAQUS coupling simulation analysis was implemented,the distribution of equivalent stress and deformation of the mold were obtained.The simulation results showed that the maximum equivalent stress of the cavity was 515 MPa,and the maximum deformation was 0.15 mm,which met the requirements of lamp mold strength and stiffness.This method can comprehensively reflect the stress and deformation of the mold cavity in the injection molding process,and can provide effective technical support for the development of similar molds.
