Abstract
본 발명은 수지 성형용 금형의 런너 분리 장치에 관한 것으로, 더욱 상세하게는 금형의 고정축 취부판에 간단히 장착하는 것에 의해 별도의 런너 플레이트를 사용하지 않고도 금형의 개방과 동시에 런너, 스푸루, 게이트를 성형품으로부터 자동적으로 분리시킬 수 있는 수지 성형용 금형의 런너 분리 장치에 관한 것이다.The present invention relates to an apparatus for separating a runner of a mold for resin molding, and more particularly to an apparatus for separating a runner, a spur, a gate and the like from a mold without opening a separate runner plate, Which is capable of automatically separating a molded article from a molded article.
본 발명에 따른 수지 성형 금형의 런너 분리 장치는 원통형의 동체와; 상기 동체의 상부에 결합되는 캡과; 하측 선단에 런너를 고착시키기 위한 언더컷이 형성되어 있으며, 상기 동체의 중앙에 길이 방향으로 설치되는 런너 록크핀과; 상기 런너 록크핀의 외주에 설치되는 슬리이브 상의 런너 이젝터와; 상기 캡과 상기 런너 이젝터 사이에 설치되어, 상기 런너 이젝터가 상기 동체의 하단 개구부 외측으로 돌출되도록 탄발력을 가하여 탄발 수단과; 상기 동체의 하단면에 가해지던 외력이 제거된 후 탄발 수단의 탄발력에 의한 이젝터의 돌출 작동을 일정시간 동안 지연시키기 위한 런너 이젝터 작동 지연 수단을 구비한 것을 특징으로 한다.The apparatus for separating a runner of a resin molding metal mold according to the present invention comprises: a cylindrical body; A cap coupled to an upper portion of the body; A runner lock pin having an undercut for fixing the runner to the lower end thereof and installed longitudinally at the center of the body; A runner ejector on a sleeve provided on the outer periphery of the runner lock pin; An elastic means provided between the cap and the runner ejector for applying an elastic force so that the runner ejector protrudes outside the lower end opening of the body; And a runner ejector operation delay means for delaying the protruding operation of the ejector due to the elastic force of the elastic means after the external force applied to the lower end surface of the body is removed, for a predetermined period of time.
