Abstract

본 발명은 저융점합금형 제작에 있어서 목형에 내열성 크리어런스 시트(clearance sheet)를 진공부압에 의해 부착할 수 있는 구조를 갖도록 한 저융점합금형의 부압장치에 관한 것으로, 그 목적은 목형의 외주면에 부착되는 크리어런스 시트를 접착제를 사용하지 않고 진공부압을 적용시켜 목형이 외주면에 부착시키므로써 단일 작업자에 의해 작업이 신속히 실행가 가능하여 작업성이 현저히 향상 될 수 있음은 물론 장기간 사용시 비용도 저렴한 저융점 합금형의 부압장치를 제공하는 것이며, 그 구성은 중앙부에 소정 직경을 갖고 관통형성되는 흡입공과, 상면 소정 위치에 상기 흡입공과 연통되게 형성되는 복수개의 흡입파이프와, 하면 소정 위치에 장착되는 복수개의 바퀴부재를 구비하는 정반과; 상기 흡기공을 통하여 흡입하기 위한 진공펌프와; 상기 흡입공과 진공펌프를 연통되게 연결하는 연결수단으로 구성되는 것을 특징으로 한다.TECHNICAL FIELD The present invention relates to a low melting point alloy negative pressure device having a structure in which a heat resistant clearance sheet can be attached to a wooden die by vacuum negative pressure in manufacturing a low melting point alloy mold. By applying vacuum negative pressure to the outer circumferential surface by applying vacuum negative pressure without using adhesive, the work sheet can be executed quickly by a single operator, which enables the workability to be remarkably improved. It is to provide a negative pressure device of the melting point alloy type, the configuration of the suction hole having a predetermined diameter in the central portion, a plurality of suction pipes formed in communication with the suction hole in a predetermined position on the upper surface, and a plurality of mounted in a predetermined position on the lower surface A plate having four wheel members; A vacuum pump for sucking through the intake hole; Characterized in that it comprises a connecting means for connecting the suction hole and the vacuum pump in communication.
