DIE FOR CONTINUOUSLY KNEADING/EXTRUSION MOLDING RUBBER

摘要

PROBLEM TO BE SOLVED: To provide a die for continuously kneading/extrusion molding a rubber, by which a rubber product having no hangnail can be molded even in the use of a rotating and reciprocating screw. SOLUTION: This die 11 can be used for a continuously kneading/extrusion molding machine provided with a screw 12 driven to rotate as well as reciprocate in a fore and aft direction. The die 11 is provided with a molding section 11b for defining the cross-sectional form of the extruded rubber. At the upstream side of the molding section 11b, a first molding region 11c having a first sectional area is formed, and a second molding region 11d having a second sectional area larger than the first is formed at the downstream side of the section 11b.
