Abstract

〔과제〕〔assignment〕

유리성형체의 시일에지의 블로우 다운을 방지할 수 있고, 이로써 냉각공기유량을 증가시킬 수 있으므로, 유리성형체의 냉각효과가 향상된다Blow down of the seal edge of the glass molded body can be prevented, thereby increasing the cooling air flow rate, thereby improving the cooling effect of the glass molded body.

〔선택수단〕[Selection means]

암금형의 상부 둘레부에 환형 부재를 배치하고, 이 환형 부재에 형성된 도입로에서 암금형내의 유리성형체의 상부 둘레부분에 있어서,의 내측에 공급된 냉각공기의 일부를, 유리성형체를 외측면에 도입하여, 유리성형체의 내측의 공기압과 외측의 공기압을 대략 동등하게 되도록 설정하여 유리성형체를 냉각한다An annular member is disposed on the upper circumference of the female mold, and a part of the cooling air supplied to the inside of the upper circumferential portion of the glass molded body in the female mold is formed on the outer surface of the inlet passage formed in the annular member. The glass molded body is cooled by introducing the inside air pressure of the glass molded body and the outside air pressure approximately equal to each other.
