Abstract

구조가 복잡하게 되거나 사출성형기가 대형화 하지 않도록 하고자하는 것으로 고정금형(12)과 가동금형(14)과를 구비하고, 가동금형(14)을 관통하여 이젝터핀(26)이 연장되며, 선단이 캐비티(21)에 면하고, 후단이 이젝터판(31,32)에 의해 고정되며 또 상기 가동금형(14)및 이젝터판(31,32)을 관통하여 가진·가압핀(35)이 연장되고 선단이 성형품의 가공부에 대응하여 수지 유로내에서 진퇴가 자유롭도록 면하며, 후단이 가진·가압판(36,37)에 의해 고정된다.
이 가진·가압판(36,37)은 상기 이젝터판(31,32)을 눌름이 자유롭도록 배설된다.
그리고 상기 가진·가압판(36,37)의 후방에 가진·가압 액츄에이터가 배설되며 이 가진·가압 액츄에이터를 작동시키므로서 가진·가압판(36,37)을 통하여 가진·가압핀(35)을 전진시키는 것이 가능함과 동시에 가진·가압판(36,37)및 이젝터판(31,32)을 통하여 이젝터핀(26)을 전진 시킬수 있는 것임.
