箱体注塑模设计

分析了箱体塑件的成型要求,设计了由两瓣合圆锥斜滑块凹模与斜槽导滑座、钩块、弹簧等配合组成的侧向分型机构;斜滑块机构实现两侧外抽芯;4组拉钩、滑座、小滑块、斜楔杆等实现顺序开模;斜顶实现两侧内侧抽芯;两组斜钩、支座、滑杆、抵杆等实现顺序合模。实践表明,该模具整体结构先进,工作可靠。

Design of Injection Mold of Housing

The molding requirements for plastic part of housing were analyzed.The side parting mechanism consists of conical inclined slide female mold,inclined slot guide support,hook block,spring,and etc.;the inclined slide block mechanism realizes the both outer side-core pulling;four units of draw hook,slide support,small slide block,inclined wedge bar,and etc.realizes the sequential parting;the inclined ejection realizes both inner side-core pulling;two units of inclined hook,support,slide bar,supporting bar,and etc.realizes sequential mold clamping.The practical production proves that the mold structure is advanced and can work reliably.
