Claims (6)
- 고정금형에 설치한 고정다이와, 가동금형의 상기 고정다이의 대향 위치에 설치한 가동다이의 사이에, 주위에 플랜지를 형성한 주물을 주조하기 위한 캐비티를 형성하고, 상기 가동금형에 압출판을 설치하여 상기 압출판에 다수의 압출핀을 그 자유단이 상기 캐비티에 노출되게 설치한 것에 있어서, 상기 압출핀 중 그 자유단이 플랜지에 위치되는 압출핀의 중심을 상기 캐비티의 외주연보다 내측에 위치되게 배치하고, 상기 압출핀의 자유단에 단턱을 내측을 외측보다 높게 형성한 것을 특징으로 한 다이캐스팅의 주물 압출 장치.
- 제 1항에 있어서, 하부금형에 가이드 핀을 설치하여 압출판의 이동을 안내토록 한 다이캐스팅의 주물 압출 장치.
- 제 1항에 있어서, 단턱에 라운딩을 형성한 다이캐스팅의 주물 압출장치.
- 고정금형에 설치한 고정다이와, 가동금형의 상기 고정다이의 대향 위치에 설치한 가동다이의 사이에 캐비티를 주위에 플랜지를 형성하는 주물을 주조할 수 있게 형성하고, 상기 가동금형에 압출판을 설치하여 상기 압출판에 압출핀의 자유단을 상기 캐비티에 노출되게 설치하여 캐비티에서 주조되어 가동다이에 고정된 주물을 압출핀으로 압출토록한 것에 있어서, 상기 압출핀 중 그 자유단이 플랜지에 위치되는 압출핀의 중심을 상기 캐비티의 외주연보다 내측에 위치되게 배치하고, 상기 압출핀의 자유단에 단턱을, 내측을 외측보다 높게 형성하여 캐비티에 융용물을 주입하여 주물을 주조할 때 상기 단턱에 융용물을 주입시켜 플랜지에 연결되는 지지돌기를 일체로 형성함으로써 주물의 압출 시 압출핀이 지지돌기에 구속되면서 고정다이 방향으로 이동되게 함을 특징으로 한 다이캐스팅의 주물 압출 방법.
- 제 4항에 있어서, 하부금형에 가이드 핀을 설치하여 압출판의 이동을 안내토록 한 다이캐스팅의 주물 압출 방법.
- 제 4항에 있어서, 단턱에 라운딩을 형성한 다이캐스팅의 주물 압출 방법.
