Abstract

상하금형이 일정한 압력으로 프레싱되어 이들 금형사이의 분말체를 성형압축하는 금형에 있어서, 제품의 산과홈을 형성하기 위해 하금형에 부여하는 돌기부와 오목부에 대향하는 위치로 상금형에 오목부와 돌기부를 적절한 높이가 되도록 부여하여 균일한 밀도로 압축성형될 수 있도록 한것을 특징으로 하는 분말체 균일 프레스 금형.In a mold in which the upper and lower molds are pressed at a constant pressure to form and compact the powder body between these molds, the recesses and the recesses in the upper mold are positioned at positions opposite to the protrusions and recesses applied to the lower mold to form the peaks and grooves of the product. Powdered uniform press mold, characterized in that the projection to be given a suitable height to be compression molded to a uniform density.

오목부와 돌기부가 각각 대향하는 위치에 형성된 상하금형으로 제품의 산부와 홈부 압축비가 일정하도록 분말 충진높이와 성형체 두께를 정하여 균일한 밀도로 분말체가 압축성형되도록 함을 특징으로 하는 분말체 균일 프레스 방법.The powder homogeneous press method, characterized in that the upper and lower molds formed in the concave and the protruding portions respectively define the powder filling height and the thickness of the molded body so that the compression ratio of the top and the grooves of the product is constant so that the powder is compacted at a uniform density. .
