MOLD FRAME STRUCTURE OF HORIZONTAL REVOLUTION DRUM IN CENTRIFUGAL MOLDING MACHINE

摘要

PURPOSE:To mold uniformly the material of respective surfaces, and increase the member rigidity in the small quantity of cement by constituting the cylindrical inner surface of a revolutional drum to be divided equally in a peripheral direction. CONSTITUTION:A concrete material is supplied in a cylindrical part 3 while keeping a horizontal revolution drum 1 to be rotated in a state wherein a material guiding and pressing member 10 is attached on the end plates in both sides. The concrete material is passed through the material guiding part 10a of the material guiding and pressing member 10, and supplied respectively into a mold frame constituted with the inner peripheral surface of the cylindrical part 3, partition members 8, 9 and the end part pressing part 10b of the material guiding and pressing member 10, and further, filled into the horizontal revolution drum 1 to be rotated by centrifugal force. By this manner, each surface of plane block 14 are respectively finished uniformly, in particular, the end pressing part 10b of the material guiding and pressing member 10 arranged on the inner surface acts to press the swell generated in both sides of inner surface of the plane block 14, and contributes to mold a plane block 14.
