EXTRUSION MOLDING MACHINE, AND EXTRUSION MOLDING METHOD

摘要

PROBLEM TO BE SOLVED: To suppress variation of an amount of clay extruded by a screw 31 and change of density at each position of a clay molded body extruded by an extrusion part 30 by pressure-feeding clay to the screw 31 on the extrusion part 30 in an extrusion molding machine which extrusion molding the clay molded body by extruding injected clay through a mouth piece at the extrusion part after degasification at a deaeration chamber.SOLUTION: A pressure-feeding part 20 is arranged in a supply passage of clay 60C feed to a screw 31 of an extrusion part 30, and clay 60B is supplied by applying pressure on a prescribed position of the screw 31 in the pressure-feeding part 20.
