ABSTRACT:
Sand is charged into a space in a mold flask by a sand feed nozzle provided on the lower end part of a blow head inserted into a sand charge port formed in the top wall of the mold flask. The blow head is further lowered after completion of the charging so as to deeply insert the sand feed nozzle in the sand charge port in order to press the sand in the vicinity of the sand charge port within the mold flask, thereby uniformly compacting the entire sand in the space.
