摘　　要：以某汽车乘客安全气囊框为例,针对其结构复杂、模具设计困难等问题,运用AMI2016对其预设浇注系统并进行仿真分析,确定采用1模1腔两点针阀式热流道浇注系统。模具结构设计了“斜导柱+滑块”和“平行导向双杆斜推”的侧向分型抽芯机构,在定模和斜推块上设计了“弹簧+推块”二次推出机构以防成型塑件粘模。模具经实际生产验证,生产的塑件满足安全气囊系统与仪表板装配要求。Taking a safety passenger airbag frame as an example,aiming at the problems of its complex structure and difficult mould design,AMI2016 was used to simulate and analyze the preset gating system,the mould with one cavity and two-point needle valve hot runner gating system was determined.The"inclined guide piller+slider"and"parallel guide double inclined ejector pin"lateral parting core pulling mechanism was designed,the secondary ejector mechanism with"spring+ejector pad"was designed in the fixed half of mould and inclined ejector pad to prevent sticking mould.The mould had been verified by actual production,and the products could meet the assembly requirements of safety airbag system and instrument panel assembly.
