EXTRUSION MOLDING MACHINE FOR CERAMIC MOLDING

摘要

PROBLEM TO BE SOLVED: To provide an extrusion molding machine for a ceramic molding capable of obtaining a high molding speed by efficiency introducing a ceramic material before kneading. SOLUTION: The extrusion molding machine for the ceramic molding comprises a screw extruder 3 and a material introducing unit 4 for introducing the ceramic material into the extruder 3. The introducing unit 4 has a case 41 including an introducing passage 410 for communicating with a housing 31 of the extruder 3 and an opening 411 for throwing the ceramic material, and a pair of right and left introducing screws 42 and 42 arranged in the passage 410 in the case 41. The screws 42 and 43 have leads 422 and 432 wound reversely to each other, are disposed so that the leads 422 and 432 are engaged in a substantially non-contact state and are rotated so that the ceramic materials are advanced in an opposite direction to the opening 411 in the engaging part.
