摘　　要：以某薄壁直桶容器为研究对象,设计了1副1模4腔的全热流道注射模。该直桶结构复杂,其底部和口底都有倒扣,且直桶口部还有倒扣卡槽,本模具设计通过二次分型和四次顶出,采用前模气缸推板、后模多次顶出与强脱、气顶等方式相结合实现产品脱模。模具采用针阀式热流道进胶,能有效提高产品质量和效率,降低了注塑成本。实践证明,该模具结构设计合理,运行可靠,注塑制品能满足生产要求。模具可为同类塑料件的注塑生产提供有益借鉴。Taking a thin-walled straight barrel container as the research object,a hot runner in⁃jection mold with one module and 4 cavities was designed.The structure of the straight barrel is complex,with buckle positions at the bottom and the mouth,and an inverted buckle groove at the mouth of the straight barrel.The mold design realizes product demoulding through secondary part⁃ing and four-time ejection,and adopts the combination of front mold cylinder push plate,rear mold multiple ejection,strong ejection and air valve.The injection mold adopts needle valve hot runner to feed glue,which can effectively improve product quality and efficiency and reduce injec⁃tion cost.Practice has proved that the mold structure design is reasonable,the operation is reli⁃able,and the injection molded products can meet the production requirements.The mold can pro⁃vide useful reference for injection molding production of similar plastic parts.
