Abstract

PURPOSE: To obtain a product excellent in dimensional accuracy by facing plates for preventing swelling provided in a fluidized bed sand layer to the external wall of a mold allowing free approach and separation and thereby preventing occurrence of swelling phenomenon.
CONSTITUTION: In baking up of a ceramic shell mold 1, a specified quantity of specified dry sand 7 is put into a molding flask 2 and pressurized air is sent into the molding flask 2 through a vent layer 5 by a pressurized air feeding tube 6. After making dry sand 7 to a fluidized bed sand layer making it a floating state in the molding flask 2, swelling preventing plates 3, 3 are opened to shift them to the wall of molding flask 2 through advancing and retreating mechanisms 4, 4 etc., the mold 1 is buried in the fluidized bed sand layer and between the plates 3, 3. Then, the plates 3, 3 are shifted as near as possible to the external wall 1a of the mold 1 and stopped. Feeding of pressurized air is then stopped, and casting is made pouring into the required mold 1.
