TILE, TILE MOLDING METHOD AND TILE MOLDING METAL MOLD

摘要

PROBLEM TO BE SOLVED: To provide a tile, a tile molding metal mold and a tile molding method capable of decreasing the generation of burrs in a tile raw material.;SOLUTION: First of all, the tile raw material 3 is thrown into a hollow space 21 (figure (a)). When a press device (illustration abbreviated) is operated to lower a cope 10 to make it abut on the upper surface 22 of a frame mold 20, the frame mold 20 is also lowered associated with the fall of the cope 10, and a cavity 50 is filled with the tile raw material 3. The cope 10 is continued to fall until the height of the upper surface 22 of the frame mold 20 coincides with the height of the forming mold surface 31 of a lower mold 30. As a result, the tile raw material 3 is filled in every corner of the cavity 50, and the surface is so constituted that the tile raw material 5 molded in the curved surface corresponding to the forming mold surface 16 of an elastic body 12 is manufactured (figure (b)). When the cope 10 is lifted after the completion of molding, a compressed spring 15 is expanded, and the elastic body 12 pushes down the tile raw material 5 to perform framework removal (figure (c)).;COPYRIGHT: (C)2004,JPO&NCIPI
