Abstract
본 발명은 상원판, 상기 상원판 아래쪽에 형합되는 하원판 및 상기 상원판과 상기 하원판 사이에 위치하는 하코어로 구성되어 있는 사출 금형에 있어서, 내부에 형성된 원통형 구멍의 하단 내주면에 보스와 환형돌기가 성형되는 형이 가공되어 있는 실린더, 상기 실린더의 상기 원통형 구멍에 삽입되며 상단에 나사머리 모양의 핀머리가 형성되어 있는 단이 진 원통형 로드 및, 전방에 T자형 홈이 형성되어 있으며 후방 끝에 유압 실린더가 구비되어 안내판 상에서 습동하도록 되어 있는 캠으로 구성되어 있는 사출금형의 외측 언더컷 처리장치에 관한 것이다.The present invention is an injection mold composed of a upper plate, a lower plate to be formed below the upper plate, and a lower core positioned between the upper plate and the lower plate, wherein the boss and the annular shape are formed on a lower inner peripheral surface of a cylindrical hole formed therein. A cylinder in which a mold is formed, which has a protrusion formed thereon, an end-shaped cylindrical rod inserted into the cylindrical hole of the cylinder, and having a screw head-shaped pin head formed at the top thereof, and a T-shaped groove formed at the front end thereof. An outer mold undercutting apparatus for an injection mold, comprising a cam provided with a hydraulic cylinder and configured to slide on a guide plate.
