Abstract

PURPOSE: To form a pouring cup quickly and accurately by pressing and connecting a pouring cup pattern having air permeability against and to a sprue rod on a pattern board and by half-solidifying a filler under vacuum.
CONSTITUTION: Film 21 is bonded to the surface of pattern board 13, having erected sprue rod 15, for a vacuum molding and casting frame 24 is matched. Next, pouring cup pattern 55 having air permeability is connected to the top of gate rod 15 and gate device 40 is opened to supply filler F from hopper 39 into the space formed of casting frame 24 and pattern board 13. After casting frame 24 is evacuated to half- solidify filler F, pouring cup pattern 55 is parted from the top of sprue rod 15 and film 21 is bonded to the top surface of filler F to solidify filler F. Then, film 21 is released from the contact with pattern board 13 to part pattern board 13.
