摘　　要：针对汽车塑料件的结构特点和技术要求,设计了一种可实现动定模开模方向斜抽芯的模具,解决了塑料件上与开模方向不平行的阶梯孔的抽芯脱模难题。模具在定模一侧设计了面板与A板可分离的二次抽芯机构,在动模一侧设计了B板与托板可分离的抽芯机构。为了配合抽芯,同时设计了顺序定距分型机构和顶针板随行机构。该模具经过试模,满足生产要求,现已投入批量生产。According to the structural characteristics and technical requirements of automotive plastic parts,we designed a mold with oblique core⁃pulling on the both sides of moving and fixed molds along the mold opening diagonally direction.This design resolved the problem that the core⁃pulling and demolding of the stepped hole was not parallel to the mold open⁃ing direction.The mould was designed with a two⁃step core⁃pulling mechanism equipped with a separable top clamp plate with the A plate on the fixed mold and a core⁃pulling mechanism equipped with a separable B plate with the support plate on the moving mould.Meanwhile,a sequential distance parting mechanism and an accompanying mechanism for the ejector were designed.The mold has been tested to meet the production requirements and has been applied for the mass production.
