Abstract

PURPOSE: To enable production of molds uniformly filled at high density at low pressurizing force to eliminate noise, by molding by pressurizing the casting sand from above and below by upper plural segments adjustable in the lowering extent and lower squeeze head.
CONSTITUTION: A molding flask 7 is carried into the specified position in a molding machine, and casting sand 8 is charged. Then, the molding flask 7 is fixed by a fixing device 6, and the casting sand 8 is pressurized by lowering the plural squeeze heads 1 by means of a hydraulic motor up to the graduation of a rotation angle detector 4 set according to the shape of a model 9. Each squeeze head 1 is constituted so as to pressurize the casting sand at an arbitrary height. At the same time, or after a specified time lag, a lower squeeze head 10 is raised until the upper surface thereof becomes level with the lower surface of the flask 7 to pressurize the sand 8. In this method, noise due to vibrator or the like does not occur, and the constitution of the forming machine is simplified, and similar molds as in the case of high pressure casting method may be molded at a small pressurizing force.
