EXTRUSION MOLDING APPARATUS

PROBLEM TO BE SOLVED: To provide an extrusion molding apparatus capable of suppressing the clogging of a molding material without raising the pressure between a conveying means such as a screw and a die. SOLUTION: The extrusion molding apparatus includes a conveying passage 2 for conveying the molding material, a die 3 provided in the conveying passage 2 and the conveying means 4 for conveying the molding material toward the die 3 and is provided with a rotary member 10 for rotating around the axis parallel to the flowing direction of the molding material between the die 3 and conveying means 4. The rotary member 10 is formed into a shape capable of shearing the molding material moved toward the die 3. The solidification of the molding material is suppressed to prevent the molding material from clogging the hole of the die 3 because the rotary member 10 is rotated so as to shear the molding material from a direction intersecting the moving direction of the molding material.
