Abstract

상이한 단면을 갖은 물품을 고압의 가스압을 이용하여 중공형으로 사출 성형시키는 경우에 응고되는 수지의 표면상에 기공부가 형성되는 것을 방지시킬 수 있거나 가스가 유동하는 가스 통로가 균일하게 형성될 수 있도록 본 발명은 승압 펌프의 작동에 의하여 가압된 가스를 다단계의 압력 상태로 유지시켜서 몰드에 주입시킬 수 있도록 가스 사출 성형 장치를 제공하는 것이다.In the case of injection molding an article having a different cross section into a hollow mold by using a high pressure gas pressure, it is possible to prevent the formation of pores on the surface of the resin to be solidified or to uniformly form a gas passage through which the gas flows. The present invention is to provide a gas injection molding apparatus so that the gas pressurized by the operation of the boost pump can be maintained in a multi-stage pressure state to be injected into the mold.
