상기 벤트유니트(1)의 작동상태를 설명해 보면, 우선 평상시에는 스프링(1j)의 탄발력에 의해 벤트유니트코어(1g)가 몰드쪽으로 이동되어, 위치조정부(1i)에 체결된 위치조정너트(1k)가 가이드부(1d)에 접하며 지지되면서, 정지부(1b)의 공기흡입구(1c)가 열려진 상태를 유지하므로, 성형공간에 슬러그가 주입되면 성형공간의 공기는 공기흡입구(1c) → 벤트유니트(1)의 관통홀 → 공기배출구(1f) → 볼트홀(5b) → 공기배출유도관(5a)으로 유도되어 외부로 방출된다.Referring to the operation state of the vent unit 1, first, normally, the vent unit core 1g is moved toward the mold by the elastic force of the spring 1j, and the position adjusting nut 1k fastened to the position adjusting unit 1i. ) Is supported while being in contact with the guide portion (1d), the air inlet (1c) of the stop (1b) is kept open, so when the slug is injected into the molding space, the air in the molding space is the air inlet (1c) → vent unit It is led to the through hole → air discharge port 1f → bolt hole 5b → air discharge induction pipe 5a of (1) and discharged to the outside.
이후, 연속적으로 주입되는 슬러그가 벤트유니트코어(1g)의 개폐부(1h)에 접하면서 개폐부(1h)를 가압하게 되면, 스프링(1j)이 눌려지면서 벤트유니트코어(1g)가 몰드(3,4) 반대쪽으로 이동되어, 개폐부(1h)가 정지부(1b)에 접하며 지지되면서, 정지부(1b)의 공기흡입구(1c)가 닫혀지므로, 슬러그가 공기흡입구(1c)를 통해서 벤트유니트(1)의 내부로 유입되지 못한다.Subsequently, when the slug injected continuously presses the opening / closing portion 1h while contacting the opening / closing portion 1h of the vent unit core 1g, the spring 1j is pressed while the vent unit core 1g is pressed into the molds 3 and 4. ) And the slug is moved through the air inlet 1c so that the air inlet 1c of the stopper 1b is closed while the opening / closing part 1h is held in contact with the stop 1b. It does not flow inside of.
바람직하기로 벤트유니트(1)는 상기와 같이 기계적으로 구성할 수 있으나, 내열성이 좋고 강도가 높은 연마석을 재료로 한 다공성 통기부재를 사용할 수도 있다.Preferably, the vent unit 1 may be mechanically configured as described above, but a porous vent member made of abrasive stone having high heat resistance and high strength may be used.
또한 공기배출 효과를 향상시키기 위해 상기 볼트홀(5b)을 진공상태로 할 수 있다.In addition, the bolt hole 5b may be in a vacuum state in order to improve the air discharge effect.
이상 설명한 바와 같이 본 고안에 의하면, 블래더가 몰드 내에서 성형될 때 몰드내에 잔류하는 에어가 볼트홀에 설치된 벤트유니트를 통하여 공기배출유도관을 따라서 몰드 밖으로 배출되므로, 블래더 성형이 원활하게 이루어지고, 성형공간 내에 잔류된 기포에 의한 블래더의 불량이 억제되는 효과가 있다.As described above, according to the present invention, when the bladder is molded in the mold, the air remaining in the mold is discharged out of the mold along the air discharge guide pipe through the vent unit installed in the bolt hole, so that the bladder molding is smoothly performed. The defect of the bladder due to the bubbles remaining in the molding space is suppressed.
