Description

성형금형용 가스빼기 장치
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본 발명의 실시예에 관한 고정금형을 도시한 정면도, 제2도는 제1도의 A-A선 단면도, 제3도는 본 발명의 실시예를 도시한 요부확대 단면도.

Claims (1)

1쌍의 성형금형에, 금형죌때 캐비티로부터 이 1쌍의 성형금형의 맞춤면 사이를 경유해서 외부에 연통하는 가스빼기통로가 형성되고, 상기 1쌍의 성형금형중 한쪽의 성형금형에, 상기 맞춤면사이의 가스빼기통로에 이 맞춤면에 대해서 거의 직교하는 방향으로부터 임하여 용탕압을 받았을때에 이 가스빼기통로와 외부와의 연통을 차단하는 가스빼기밸브가 착설되어 있는 성형금형용 가스빼기 장치에 있어서, 상기 가스빼기밸브에, 상기 1쌍의 성형금형중의 다른쪽의 성형금형에 대향하도록 해서 오목부가 형성되고, 상기 다른쪽의 성형금형에, 금형죌때 상기 오목부에 끼워맞추는 돌출부가 형성되고, 상기 가스빼기 통로는, 상기 돌출부를 타고 넘도록 설정되어 있는, 것을 특징으로 하는 성형금형용 가스빼기장치.
