摘　　要：分析了塑件的注射成型要求,设计了一种汽车滤清套盖倒装式无顶出点浇口模具。为实现塑件表面无浇注残留痕迹,模腔成型件采用倒装式安装于模具上,型腔镶件安装在动模板上,型芯镶件安装在定模板上,保证了点浇口开设在塑件的内壁上,避免了塑件外观受浇注痕迹及顶出痕迹的影响。模具为六板式非标模架结构,分五次分型打开,其中三次打开用于流道废料的去除,一次打开用于塑件内壁倒扣的脱模,一次打开用于塑件推板推出的完全脱模。针对内壁倒扣,通过模板驱动两个T型槽锁紧块来驱动两个内滑块实施侧抽芯。The injection molding requirements of plastic part were analyzed,and an inverted gate mold without ejection point for automobile filter cover was designed.In order to realize no casting residual trace on the surface of plastic part,the mold cavity molding part is installed on the mold in the inverted form,and the cavity insert is installed on the moving template,and the core insert is installed on the fixed template,which ensures that the point gate is set on the inner wall of plastic part,and avoids the influence of the pouring trace and ejection trace on the appearance of plastic part.The mold is six plate non-standard mold base structure,which is divided into five times to open,including three times for the removal of the channel waste,one time for demoulding the reverse buckle of the inner wall of plastic part,and one time for the push plate push-out complete demoulding of the plastic part.For the inner wall undercutting,two T-groove locking blocks are driven by the template to drive two inner sliding blocks to implement side core pulling.
