Abstract

타이어 가류기에 벤트리스 밸브(1)를 장착하고 그 밸브(1)에 진공파이프(3) 및 공기압 파이프(4)가 T자형으로 연결된 흡배기 파이프(1)를 연결하되 상기 진공파이프(3)와 공기압파이프(4)에는 각각 밸브(V1)(V2)를 장치한 가류몰드(2)와 이를 이용하여 가류시작시에는 진공파이프(3)로 내부 공기를 빼고 가류후는 공기압파이프(4)로 공기를 내부에 주입하여 미리 몰드로부터 타이어의 트레부를 분리시킨후 타이어를 인출함으로써 몰드의 그루브 또는 커퍼에 의한 타이어의 손상을 감소시킨 것이다.A ventless valve (1) is mounted on the tire vulcanizer, and a vacuum pipe (3) and a pneumatic pipe (4) are connected to the valve (1) with an intake and exhaust pipe (1) connected in a T-shape, but the vacuum pipe (3) and the air pressure are connected. Each of the pipes 4 has a vulcanization mold 2 equipped with valves V1 and V2, and when the vulcanization starts, the internal air is drawn out with a vacuum pipe 3, and after vulcanization, the air is blown with a pneumatic pipe 4. It is injected inside to separate the tre portion of the tire from the mold, and then the tire is taken out to reduce the damage of the tire by the groove or the cupper of the mold.

Description

벤트리스 밸브를 이용한 가류타이어의 인출방법 및 장치Extraction method and apparatus of vulcanized tire using ventless valve

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명의 벤트리스 밸브를 장착한 상태의 몰드의 종단면도.1 is a longitudinal sectional view of a mold in which the ventless valve of the present invention is mounted.

제2도는 본 발명의 벤트리스 밸브를 장착하고 진공 및 공기압 파이프와 연결한 몰드에 그린케이스를 인입후 진공관으로 내부공기를 인출한 상태의 종단면도.2 is a longitudinal cross-sectional view of a ventless valve of the present invention and drawn out of internal air through a vacuum tube after introducing a green case into a mold connected to a vacuum and pneumatic pipe.

제3도는 본 발명의 벤트리스 밸브를 장착하고 진공관 및 공기압 파이프와 연결한 몰드에 그린케이스를 인입후 공기압관으로부터 공기를 주입시켜 가류된 타이어를 몰드로부터 미리 분리시킨 상태의 종단면도이다.3 is a longitudinal sectional view of a state in which the vulcanized tire is separated from the mold in advance by injecting air from the pneumatic pipe after introducing the green case into the mold to which the ventless valve of the present invention is connected and connected to the vacuum tube and the pneumatic pipe.

Claims (1)

투피스로된 타이어의 가류 몰드에 있어서, 가류를 완료하여 블레더 내부의 압력을 배출한 다음 공기압 파이프(4)와 연결된 공기압 밸브(V2)를 열고 벤트리스 밸브(1)를 통하여 몰드(2)(2') 내부로 수초간 공기를 공급하여 가류된 타이어 트레드 표면(11)을 몰드(2)로부터 수평방향으로 밀어내어 몰드(1)로부터 타이 트레드를 분리시킨후 공기압 밸브(V2)를 닫고 타이어를 인출함을 특징으로 하는 벤트리스 밸브를 이용한 가류타이어의 인출방법.In the two-piece tire vulcanization mold, the vulcanization is completed to release the pressure inside the bladder, and then the pneumatic valve V2 connected to the pneumatic pipe 4 is opened and the mold 2 (through the ventless valve 1) ( 2 ') supplying air for a few seconds to push the vulcanized tire tread surface 11 horizontally away from the mold 2 to separate the tie tread from the mold 1, then close the pneumatic valve V2 and close the tire. A withdrawal method of a vulcanized tire using a ventless valve, characterized in that drawing out. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
