Abstract

본 발명은 사출성형을 위한 시스템에 관한 것으로, 특히 수지 손실을 줄이고 성형품질을 높일 수 있는 사출시스템 중 용융 수지를 분배하는 분배수단 및 노즐 각각이 외부금형 및 금형과 접하는 부위에 단열수단을 구비하고 있어 분배수단과 노즐의 잦은 재가열로 인한 에너지 손실 및 재가열에 따른 용융수지 변성을 방지하여 성형품질을 개선할 수 있도록 한 사출시스템에 관한 것이다. 본 발명에 따른 사출시스템은 사출기로부터 공급된 용융수지를 분배하도록 주입구와 배출구를 갖고, 전열부재를 구비한 분배수단; 상기 분배수단의 배출구에 구비된 노즐; 및 상기 노즐과 접하고, 스페이스를 갖는 금형;을 포함하여 이루어지되, 상기 노즐과 금형의 접면에는 제1단열수단이 구비되어 있고, 상기 제1단열수단은 금속면에 형성된 외곽보호부에 의하여 감싸져 있는 내화물층인 것을 특징으로 한다.
