Abstract

카세트식 사출 금형 장치의 파손을 방지한다.Prevents breakage of the cassette injection mold apparatus.

가동측 금형(Q)의 양측부에 광센서(25)를 설치하며, 가동측 베이스 플레이트(16)에 관통 구멍(16b)을 설치하여 광센서의 검출용 빛을 통과 가능하게 하고 있다. 제1이젝터기구(19)에 의해 제2이젝터 기구(22)가 진출하면 이젝터 플레이트(23)가 진출하여 관통 구멍의 중간 위치를 차단하기 위해 광센서925)의 검출용 빛은 수광소자(29)에 도달하지 않는다. 제2이젝터 기구(22)가 원위치에 복귀하여 있을 때에는 검출용 빛은 관통 가능하게 되기 때문에 수광 소자(29)에 도달 가능하다. 광센서에서의 제어 신호에 의해 성형기의 동작이 제어되기 때문에 이젝터 핀(24)이나 리턴핀등이 돌출 상태의 그래도 틀 받힘을 방지하며 금형 장치의 파손이 방지된다. 다른 수단으로서는 검출용 빛이 분리선 면에 따라서 통과하도록 광센서를 설치하여 리턴핀의 상태를 직접적으로 검출 가능하다.Optical sensors 25 are provided on both sides of the movable side mold Q, and through holes 16b are provided in the movable base plate 16 to allow light for detection by the optical sensor to pass therethrough. When the second ejector mechanism 22 advances by the first ejector mechanism 19, the light for detecting the optical sensor 925 is transferred to the light receiving element 29 so that the ejector plate 23 advances and blocks the intermediate position of the through hole. Does not reach. When the second ejector mechanism 22 is returned to its original position, the light for detection can pass through and thus can reach the light receiving element 29. Since the operation of the molding machine is controlled by a control signal from the optical sensor, the ejector pins 24 and the return pins prevent the mold from being projected in the protruding state and prevent the mold apparatus from being damaged. As another means, an optical sensor may be provided so that the detection light passes along the separation line surface so that the state of the return pin can be directly detected.
