摘　　要：针对强力电锤仿生手柄管位多、筋位多、需要大侧面抽芯脱模复杂结构的特点,经过塑料件结构分析、注塑成型工艺分析以及模具设计计算,设计了完整的三板模模具结构。模具结构主要采用3种侧抽芯机构的结构设计,包括N2螺孔特征前模T型槽抽芯机构、手柄端面特征T型槽镶件抽芯芯机构、安装台特征斜滑块上座顶针板二次脱模侧抽芯机构;通过计算与分析给出了准确的模具设计参数;通过机构创新设计,降低了模具的设计难度以及保证了机构的可靠性与经济性。经生产实践验证,模具整体结构简单,可靠性好,制作周期短,较好地满足了生产需求。Aimed to a strong-electric hammer with bionic-handle which with complex structures and lots characteristics such as tube, rib and great area side face that needed to be core side pulled,through analysis of the structure ofplastic parts, injection molding process analysis and mould design calculation,a complete three board injecting mould structure design was given. Mould structure was designed mainly for adopting three kinds of core side pulled mechanism that included the first mechanism which called N2 screw character that used T type groove core side pulled mechanism, and the second mechanism which called the end face of the handle features which used T type groove insert core side pulled mechanism, and the third mechanism which called installation plate character with a side pulled core mechanism which located on a inclined sliding block seat where installed ejector plate secondary demoulding. Through calculation and analysis, the accurate parameter of mould design was given, through the mechanism innovation design, the difficulty of the mould design was reduced and the reliability and economy were ensureed. The production practice proves that the mold has a simple structure, good reliability and shorted the production cycle, which can meet the demand of production.
