Abstract
본 발명은 가스 사출 성형기에서 사출직후 내부에 잔류하는 가스를 강제로 배기하여 사출품의 결함을 조래하는 현상을 방지하는 가스사출 강제 배기장치를 제공한다.The present invention provides a gas injection forced exhaust system for preventing a phenomenon in which a gas remained in the interior of a gas injection molding machine immediately after injection is forcibly exhausted, thereby preventing a defect in a product from being smeared.
그 가스사출 강제 배기장치는, 소정의 진공압을 형성하는 진공펌프(29); 상기 진공펌프(29)와 노즐(16)사이에 배관연결 되는 배출 도관(27); 상기 배출도관(27)상에서 노즐(16)과의 최단거리 지점에 장착되는 개폐밸브(25); 그리고 상기 배출도관(27)상에 장착되고, 상기 개폐밸브(25)의 온 오프제어 출력을 발생하는 가스배출 제어기(28)를 포함하는 것을 특징으로 하는 가스사출 강제 배기장치를 제공한다.The gas injection forced exhaust apparatus comprises a vacuum pump (29) for forming a predetermined vacuum pressure; A discharge conduit 27 piped between the vacuum pump 29 and the nozzle 16; An on-off valve (25) mounted on the exhaust conduit (27) at a shortest distance from the nozzle (16); And a gas discharge controller (28) mounted on the discharge conduit (27) for generating an on / off control output of the on / off valve (25).
이에 따라, 가스 사출 성형기에서 공급된 질소가스가 완전히 배출되도록 배기장치를 연결하고 적절한 진공압을 형성시킴으로써, 질소가스가 사출성형품에 미치는 표면 요철 및 색상변질 등의 결함을 방지하는 효과가 있다.Accordingly, there is an effect of preventing defects such as surface irregularities and color change on the injection-molded product due to the nitrogen gas by connecting the exhaust device and forming an appropriate vacuum pressure to completely exhaust the nitrogen gas supplied from the gas injection molding machine.
Description
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is a trivial issue, I did not include the contents of the text.
