Claims (2)
- 합성수지로 박판 플라스틱제품을 성형하는 핫런너 밸브 장치에 있어서, 노즐바디(7)의 외주면에서 제2의 승강피스톤(3)에 의해 승강되고 하단 일측에는 측면 탕도(5)와 관통되는 관통공(6)이 천설되며 하강시에 하단이 밸브게이트(8) 하단보다 약간더 하강되도록 장착된 슬리브핀(4)을 상부의 승강피스톤(1)에 장착되어 승강되는 니들핀(2)의 외주면에서 승강되게 외삽한 것으로 구성됨을 특징으로 하는 박판 플라스틱 성형용 핫런너 밸브 장치.
- 핫런너 밸브 장치에 의해 합성수지로 박판 플라스틱 제품을 성형함에 있어서, 슬리브핀(4)의 하단이 밸브게이트(8)의 하단과 일치하면서 측면 탕도(5)와 슬리브핀(4)의 하단 측면 관통공(6)이 일치되어 관통되도록 하강시킨 상태에서 내부의 니들핀(2)을 상승시킨 후 측면 탕도(5)를 통하여 용융 합성수지를 주입하여 박판금형내에 용융합성수지가 채워지게한 다음 슬리브핀(4) 하단의 금형과의 공극(9)에까지 용융합성수지가 채워지도록 하고 이때 슬리브핀(4)을 하강시켜 공극(9)의 끝까지 닿게함과 동시에 니들핀(2)도 하강시키게되면 슬리브핀(4)과 니들핀(2)의 하강 행정거리의 차이에 의해 금형의 공극(9)에 과잉 투입되었던 합성수지는 탕도(5)로 역류하면서 박판 플라스틱 성형품의 상단이 평평하게 성형되도록 함을 특징으로 하는 박판 플라스틱 성형용 핫런너 밸브 장치.
