- 사출기의 호퍼에 공급된 액상 고무가 상기 사출기의 노즐부로부터 공급되어서, 금형 본체의 스프루부시를 통하여 캐비티에서 성형되도록 구성된 액상 고무 사출 성형기로서,
상기 노즐부의 출구단은, 상기 노즐부의 고무 통로와 접하는 부분이 주둥이 형상으로 돌출된 제1 볼록부와,상기 제1 볼록부에 접하여 형성되며 상기 제1 볼록부보다 큰 반경을 가지면서 볼록하게 형성된 제2 볼록부를 포함하고,
상기 금형 본체의 스프루 부시는, 금형 본체의 스프루와 접하는 부분이 상기 주둥이 형상에 대응되는 형상으로 오목하며 상기 제1 볼록부와 접하는 제1 오목부와, 상기 제1 오목부로부터 연장 형성되며 상기 제2 볼록부와는 이격되도록 형성된 제2 오목부를 포함하며,
상기 제1 볼록부 및 제1 오목부는 동일한 반경을 가지며 볼록 및 오목하게 형성된 것을 특징으로 하는 액상 고무 사출 성형기. - 제2항에 있어서,
상기 제2 볼록부의 반경은 상기 제1 볼록부의 반경 대비 2배 내지 4배인 것을 특징으로 하는 액상 고무 사출 성형기. - 제2항에 있어서,
상기 노즐부는, 상기 제1 볼록부와 제2 볼록부 사이를 연결하는 것으로서 오목한 형상을 하는 오목 연결부를 포함하고,
상기 제2 볼록부의 반경은 제1 볼록부의 반경 대비 2배 내지 4배이고,
상기 오목 연결부의 반경은 제1 볼록부의 반경 대비 1 내지 1.5배인 것을 특징으로 하는 액상 고무 사출 성형기.
