Abstract (en)
[origin: EP1832358A1] In blowing gas-curing casting sand 41, which is accommodated in a receiver 2 of a blow head 1, into a cavity 36 in molding dies 35 and thereby packing it into the cavity 36, prior to the blowing and packing of the casting sand 41 into the cavity 36, the casting sand 41 in the receiver 2 is stirred by a stirrer 21 until the stirring resistance of the stirrer 21 enters a predetermined range (a range corresponding to an optimum bulk density range of casting sand within which casting sand 41 can efficiently blow out through blow nozzles 9 ).
