Abstract
A cast mold fabricating device supplies thickener-coated sand and steam into a mold forming die at an optimum timing to shorten a mold fabrication time. The device includes the die 2 with an injection inlet 1, a sand supply head 4 for supplying and filling the thickener-coated sand 3 into the die, a steam supply head 5 for supplying steam into the die 2 to solidify and/or cure a thickener of the sand by application of heat of the steam. The device further includes a vertical drive 6 for lowering the sand supply head 4 to a position where the injection inlet 1 is connected to a sand nozzle 8 of the sand supply head 4, and a horizontal drive 7 for advancing the steam supply head 5 to a position where the injection port 1 is connected to a steam nozzle 9 of the steam supply head 5.
