ABSTRACT:
A mold apparatus and method for minimizing the amount of chemically bonded molding sand needed to form a block mold which consists of a flask mounted upon a pattern plate and a sand minimizer blow plate which is selectively movable into engagement with the upper edge surface of the flask mounted upon the pattern plate so as to form a mold cavity therewith into which the chemically bonded molding sand is blown so as to form the sand mold. The sand minimizer blow plate is provided with pocket forming finger extensions which extend downwardly into the mold cavity so as to form block sand minimizer pocket cavities in the completed sand mold.
