EXTRUSION-MOLDING DEVICE AND METHOD FOR PRODUCING MOLDED ARTICLE USING SAME

摘要

An extrusion-molding device of the present invention includes: a housing having a channel that transfers a pasty raw material composition; a screw provided upstream of the channel that kneads the raw material composition and transfers the raw material downstream; a die provided downstream of the channel that extrudes a molded article made up of the raw material composition; a resistive tube that connects the channel and the die; a flow rate adjustment plate provided between the screw and the die that is detachable with respect to the housing and that has a plurality of through holes penetrating in a thickness direction; and an upstream blocking member that is detachable with respect to an upstream face of the flow rate adjustable plate and that simultaneously blocks upstream openings of some through holes of the plurality of through holes in a state of being attached to the flow rate adjustable plate.
