  • Compression molding machine for briquette for metal raw material, manufacturing apparatus for briquette for metal raw material, and compression molding method thereof
    Patent number: 7824586
    Abstract: There is provided a compression molding machine capable of manufacturing briquettes by compression molding a material efficiently. The compression molding machine includes a mold device (12) formed with a molding chamber and a plunger (15) provided so as to be capable of advancing and retreating in the axial direction to compression mold the material in the molding chamber. The molding device (12) includes an axially fixed pressure receiving member (16) facing to a tip end surface (15a) of the plunger (15), an outside mold (44) in sliding contact with the outer peripheral surface of the plunger (15), and supporting means which supports the outside mold (44) so that the outside mold (44) moves in an extrusion direction of the plunger (15) in association with the movement of the plunger (15) in the extrusion direction.
