摘　　要：针对电动剃须刀外壳特点 ,为解决脱模时成 12 0°的两个方向上抽芯机构之间的运动干涉 ,设计了动模板与斜向哈夫滑块组合结构 ,采用滑槽限定球头滑块并利用了弹簧辅助顶出的斜向抽芯机构 ,整副模具构思巧妙 ,结构合理 ,动作可靠 。In view of properties of electrical razor shell, special inner surfaces of plastic pieces are designed with the use of combined moving molding board and oblique pace block to avoid motion interference on the direction of 120° between core-drawing mechanisms when demoulding. Spring assisted pumped oblique core-drawing mechanisms on which spherical pace blocks are limited by runners are adopted. The whole mould is simple and full of ingenuity,has reasonable structure,moves reliably and demoulds successfully.
