Abstract

이젝터장치의 내구성을 향상시키고, 사출성형기의 주위를 더럽히지 아니하도록 한다. 이를 위하여, 고정플래튼과 마주하여 타이바를 따라 진퇴가 자유롭게 배설되는 가동플래튼과, 이 가동플래튼과 토글서포드와의 사이에 배설되며 가동플래튼을 진퇴시키는 토글기구와, 상기 가동플래튼에 고정되고, 스테이터 및 로터로부터 되는 서보모터와, 상기 로터에 고정되는 중공축과, 이 중공축에 고정되는 볼너트와, 이 볼너트와 나사결합하여, 볼너트의 회전에 따라 진퇴되는 볼나사축과, 상기 볼나사축과 연결되어 진퇴되는 크로스헤드와, 이 크로스 헤드와 연결되는 이젝터핀과를 갖는다. 상기 서보모터를 구동하여 중공축을 회전시키며, 볼나사축을 통하여 크로스헤드를 전진시키는 것에 의해, 이젝터핀을 전진시켜, 성형품을 돌출할 수가 있다. 타이밍벨트를 사용할 필요가 없으므로, 이젝터장치의 내구성을 향상시킬 수 있음과 동시에, 사출성형기의 주위를 더럽히지 아니한다.
