PURPOSE: To obtain the method for manufacturing an elastometric resin molded form capable of positively removing a burr formed at the time of molding rapidly by molding the elastometric resin molded form, opening a top force and pushing a cutting edge mold, in which a cutting edge is fitted at a specified position, against the molded form.

CONSTITUTION: The pin 22 of a cutting edge mold 16 before a molded form is extracted is positioned and placed concentrically to a bottom force section 2. When the cutting edge mold is pushed downward under the state, cutting edges 17 cut a burr 23. An elastometric resin decorating 24 is acquired by extracting the molded form. Accordingly, there are no cutting-residue and over- cutting of the burr, thus removing the burr to desired size at all times.
