Abstract

사출금형용 핫트런너 오픈 노즐에 있어서, 수지흐름탕도(17)를 핫트런너오픈노즐(1)내부에 설치하고 그 외벽에 가열 장치인 히터(4)와 센서(5)를 설치, 탕도내의 용융된 수지흐름의 흐름을 더욱 원활히 하여 압력 손실을 최소화했으며, 핫트런너오픈노즐(1)의 전도에 의한 열로 수지를 항상 일정한 온도로 용융시킬 수 있으며, 따라서 과열에 의한 수지의 탄화 현상을 할 수 있는 외부가열 방식을 채택하면서, 핫트런너오픈노즐(1) 선단부는 별도의 분리 가능한 핫트런너팁(3)을 열절달이 좋은 소재로 했으며, 핫트런터팁(3)과 핫트런너오픈노즐(1)을 고정할 수 있는 별도의 핫트런너 고정용 와셔(2)를 설치했으며, 이로 인하여 금형 분해, 조립시 문제가 발생하면 현장에서 조치가 특시 가능한 구조로 되어 있고, 또한 고객의 요구에 따른 성형수지 교환 및 색상 교환이 탕도 내부에서 완전히 이루어질 수 있는 제품으로 발명 되었으며, 금형과 핫트런너 노즐 가열장치인 히터(4)와 공기 단열층(13)을 설치하여 금형의 온도 상승을 억제시킬 수 있는 사출금형용 핫트런너 오픈 노즐이다.In the injection mold hot runner open nozzle, a resin flow diagram (17) is installed inside the hot runner open nozzle (1), and a heater (4) and a sensor (5), which are heating devices, are installed on the outer wall thereof to melt the water in the furnace. The flow of the resin flow was smoothed to minimize the pressure loss, and the resin was always melted at a constant temperature by the heat of the hot runner open nozzle 1, so that the carbonization of the resin could occur due to overheating. Adopting the external heating method, the tip of the hot runner open nozzle (1) is made of a good heat transfer material with a separate detachable hot runner tip (3), and the hot runner tip (3) and the hot runner open nozzle (1) A separate hot runner fixing washer (2) that can be fixed is installed, and if this causes problems in disassembling and assembling the mold, it has a structure that can be specially handled in the field. color It was invented as a product that can be exchanged completely inside the waterway, and an injection mold hot runner that can suppress the temperature rise of the mold by installing a heater 4 and an air insulation layer 13, which is a mold and a hot runner nozzle heating device, is opened. Nozzle.
