Mold for foam molding and foam molding method

Abstract

A moldB for foam molding which allows efficient production of the foam molded product with accurately finished outer surface, and easy release of the molded product from the mold in the foam molding method is formed of an upper mold portionB and a lower mold portionB. The gas feed meansformed of the valve box, the valve elementand the like is attached to an opening formed in the bottom surface of the lower mold portionB. The recess portionsare formed in each part of the opposite side surfacesandof the cavity. The protruding portionsare formed on the lower surface of the upper mold portionB so as to be fit to the corresponding recess portion. Upon completion of curing, the upper mold portion is separated to open the mold, air is supplied into the valve boxsuch that air is fed to a space between the molded productB and the bottom surface of the lower mold portionB to push up the molded productB so as to be released from the mold. The empty spaces formed by extraction of the protruding portionsallow insertion of the tool and finger thereinto to take the molded productB from the mold.
