Abstract

PURPOSE:To improve quality of a mold by squeezing molding sand by ascending/ descending squeeze plate, injecting compressed air from the whole face of the squeeze plate and pressurizing the molding sand by jetting. CONSTITUTION:The upper and lower squeeze plates 5, 4 are respectively arranged at opening parts of upper and lower molding flasks 3, 2 and also many vent holes 6 are arranged on contact face thereof with the molding sand. Further, air introduced space 7 for introducing compressed air and molding sand introduced passages 8, 8' are arranged at back face of the plates 5, 4. At the time of molding by packing the molding sands 14, 14' into casting spaces 13, 13', by injecting compressed air from the vent holes 6, 6 at the same time of ascending/descending the squeeze plates 5, 4, the jetting pressurization is executed. By this method, the molding having high density at projected part and recessed part in a pattern part 16, 16' are uniformly executed. By synergetic effect of the jetting pressurization and the squeeze, the quality of the mold is improved.
