Abstract

간이한 구성에 의해 프로우브의 선단부분(팁部)을 간헐적으로 가열하는 히터와 프로우브의 보디부를 가열하는 히터를 함께 단일의 전원으로부터 급전가능한 사출성형금형용 프로우브 및 러너레스 사출성형장치로서, 통전에 의한 온도상승에 수반하여 전기저항값이 급상승하는 백금 또는 백금합금에 의해 구성한 팀히터(7)를 선단부분(3)에 배설하여, 통전에 의한 온도상승이 수반하는 전기 저항값의 상승이 작은 니크롬선에 의해 구성한 보디히터(8)를 보디부분(2)에 배설하여, 팁히터(7)와 보디히터(8)은 직결접속상태에 있는 사출성형금형용 프로우브(1a)와 동 사출성형금형용 프로우브(1a)를 금형의 게이트부에 장착하고, 성형공정에 동기(同期)로 하여 전력제어하여 전기 팁 히터(7)와 보디히터(8)에 직렬급전하는 전원장치를 갖춘 러너레스 사출성형장치. (대표도면 : 제1도)
