摘　　要：针对一款碎纸机上壳塑件,为解决塑件表面进胶出现浇口痕的问题,特别设计了一副复杂倒装结构的后模进胶方式的热流道模具。通过设计机械拉勾的方式完成顶出动作。鉴于塑件四周倒扣和内部骨位多的结构特性,后模侧向设计了四边滑块拼接抽芯方式脱模;后模芯设计了多处镶件结构,方便加工、防止困气、提高成型效率及品质。量产过程中,模具各机构运行平稳,塑件品质优秀,符合设计要求。To address the problem in the existence of gate marks on the surface of a shredder shell plastic part,a hot run-ner mold with a complex inverted structure and a rear mold feeding mode was designed.The ejection action was complet-ed through designing mechanical hooks.Considering the structural characteristics of the plastic parts with multiple invert-ed buckles surround them and internal bone positions,a four-sided slider splicing and core-pulling mechanism was de-signed for demolding on the lateral side of the rear mold.The back mold core was designed with multiple insert struc-tures,which facilitated the processing,prevented the air trapping,improved the molding efficiency and quality.During the mass production,the various mechanisms of the mold operated smoothly,and the quality of the plastic parts was ex-cellent,which could meet the requirements of design.
