Abstract

본 발명은 자동차의 트림, 특히 도어 트림을 성형하기 위한 진공성형기의 진공성형 보조장치에 관한 것이다.The present invention relates to a vacuum forming aid of a vacuum molding machine for forming a trim of a motor vehicle, in particular a door trim.

본 발명은 진공성형가능의 금형⑶상에 기밀하게 밀착가능하고 양측에 플랜지(11a,11b)가 형성되며 중앙에 호스연결구멍⑽이 형성되는 압공박스⑹와, 하향작동가능하고 상기 압공박스⑹의 양측 플랜지(11a,11b)가 저면 양측에 클램핑되는 상형⑺ 및 상기 호스연결구멍⑽을 통하여 압공박스⑹내에 압축공기를 공급할 수 있는 에어탱크⑻로 구성시킨 것이다.The present invention provides a pressurized box 가능 which is hermetically tightly sealed on a vacuum moldable mold 하고, and flanges 11a and 11b are formed at both sides thereof, and a hose connection hole 에 is formed at the center thereof, and is downwardly operable. Both flanges (11a, 11b) is composed of an upper tank (되는) clamped on both sides of the bottom surface and an air tank (수) capable of supplying compressed air into the pressure box (⑹) through the hose connection hole (⑽).

압공박스⑹가 금형⑶상에 밀착되었을 때 진공성형과 동시에 에어탱크⑻의 압축공기가 압공박스⑹내에 주입되면 도어 트림⑸이 진공에 의하여 금형⑶에 밀착됨과 동시에 압축공기에 의하여 표면에 고르게 압력이 작용하기 때문에 도어 트림⑸은 표면의 엠보가 소멸되지 않으면서 금형⑶과 일치하는 형상가 치수가 정도있게 확보되는 것이다.When the compressed air box 착 is in close contact with the mold 되면 If the compressed air of the air tank 주입 is injected into the pressure ⑹ box at the same time as the vacuum molding, the door trim 착 is closely adhered to the mold 의하여 by vacuum, and the pressure is evenly applied to the surface by the compressed air. As a result, the door trim ⑸ ensures that the shape corresponding to the mold 치수 is dimensionally secured without embossing of the surface.
