Description
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본 발명장치의 개요 구성도.
제2도는 사출 실린더 압력과 2차 가압 실린더 압력과의 관계를 표시하는 그래프.
제4도는 2차 가압 타이밍과 파단 하중과의 관계를 표시하는 그래프이다.
Claims (1)
- 금형내에 삽입되는 가압 플런저를 갖춘 2차 가압 실린더가 금형의 한쪽에 고정 설치됨과 동시에 사출 실린더내의 압력상승을 검지하여 작동하는 소정의 유압원에 접속된 시퀀스 밸브와, 이 시퀀스 밸브와 상기 2차 가압 실린더와의 사이에 유량 조절밸브와 감압밸브가 장치되어 상기 시퀀스 밸브의 조정에 의해서 상기 2차 가압 실린더의 작동개시 시점을 변경하고, 상기 유량 조절 밸브에 의해서 가압 플런저의 진행속도를 가변시키고, 상기 감압밸브의 조절에 의해서 상기 가압 플런저의 가압력 변경을 가능하게 한 것을 특징으로 하는 다이캐스트 장치.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
