外壳注塑模具

Abstract

本实用新型公开了一种外壳注塑模具，包括面板、定模夹板、定模板、动模板、夹板弹簧、第一抽芯组件、第二抽芯组件、第三抽芯组件；所述面板、定模夹板固定在一起，定模夹板、定模板、动模板依次靠接在一起，在定模夹板与定模板之间设有夹板弹簧；所述第一抽芯组件的上端固定在面板上，第二抽芯组件的上端固定在定模夹板上，第三抽芯组件的上端固定在定模板上。开模时，定模夹板在夹板弹簧的推动下先与定模板分离，第二抽芯组件中的第二滑块镶件在镶件弹簧的驱动下升起并与限位铲基上的凸沿顶靠，实现塑料产品倒扣的脱模，同时第二、第三抽芯组件完成抽芯动作。本实用新型在一套模具中可生产具有导光元件的塑料产品，节约了人工装配成本。
