MANUFACTURING METHOD OF MOLD FOR FOAM ARTICLE

摘要

PURPOSE: A manufacturing method of a mold for a foam product is provided to reduce manufacturing time and manufacturing cost by simultaneously processing a plurality of steam holes to the cavity mold and/or core mold. CONSTITUTION: A manufacturing method of a mold for a foam product comprises a step of individually molding a cavity mold and/or a core mold alternately formed in a plurality of thick body parts and a plurality of thin body parts (S1); a step of processing a plurality of steam holes in the thin body part of the cavity mold and/or core mold (S2); and a step or post-processing a cavity mold and/or core mold (S3). The cavity mold and/or the core mold have a structure in which a plurality of mold segments are assembled. In the extrusion molding step, the cavity mold and/or the core mold are individually extruded.
