Abstract: A sand-mold molding method for producing a molded article obtained by packing foamed sand may include stirring a binder with an aggregate to form foamed sand; forming a cavity via clamping a metallic mold closed; packing the foamed sand into the cavity of the metallic mold and then heating and solidifying the foamed sand; and opening the metallic mold partially to provide a gap in the metallic mold while maintaining the cavity.

Abstract: A mold-making device may include a stirring device including a stirring tank and at least one stirring blade. The stirring device may further include a packing port that is configured to open and close on a bottom of the stirring tank. The stirring device may stir a particulate aggregate and at least one additive by rotating the at least one stirring blade within the stirring tank to yield an admixture. A forming mold may communicate with the packing port and mold the admixture into a predetermined shape. A packing device may compress a surface of the admixture within the stirring tank and pack the admixture into the forming mold via the packing port.
