Compression Molding Machine for Briquette for Metal Raw Material, Manufacturing Apparatus for Briquette for Metal Raw Material, and Compression Molding Method Thereof

摘要

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 ( 15 a) 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.
