Abstract
본 발명은 사출 성형용 금형의 수지 흘러내림 방지장치에 관한 것으로, 고정측 형판(11)의 내부에 삽입 설치되는 핫 런너 노즐(12)의 하단부에 하면이 고정측 형판(11)과 동일 평면을 이루도록 나사 결합되고 수지 주입공(13a)의 하부에 단턱면(13b)이 형성된 핫 런너 팁(13)과, 상기 핫 런너 팁(13)의 수지 주입공(13a)에 승강가능하도록 결합되어 완전하게 하강된 상태에서 고정측 형판(11)의 하면으로부터 일정 길이(P)만큼 돌출되고 핫 런너 팁(13)의 단턱면(13b)에 의하여 개폐되는 수개의 런너(14a)가 형성된 셧 오프 핀(shut off pin)(14)과, 상기 핫 런너 팁(13)의 내부에 삽입되어 셧 오프 핀(13)을 하향으로 탄력지지하는 압축스프링 등의 탄성부재(15)로 구성하여 금형의 개방과 동시에 핫 런너 팁의 유로를 즉시 차단함으로써 수지가 임으로 흘러내리는 현상을 방지하도록 한 것이다.The lower end of the hot runner nozzle (12) inserted into the fixed side mold plate (11) is flush with the fixed side mold plate (11) A hot runner tip 13 having a stepped surface 13b formed at the lower portion of the resin injection hole 13a so as to be able to move up and down to the resin injection hole 13a of the hot runner tip 13, A shutoff pin shut having a plurality of runners 14a protruding from the lower surface of the fixed side mold plate 11 by a predetermined length P and being opened and closed by the stepped surface 13b of the hot runner tip 13, and an elastic member 15 such as a compression spring inserted into the inside of the hot runner tip 13 and supporting the shut-off pin 13 in a downward direction, The flow path of the runner tip is immediately blocked to prevent the resin from flowing down It is.
