A mold device includes a frame that is a vertical wall having a first surface that is a vertical surface to which a holding mechanism is mounted and supported only by the first surface. A fixed mold base supporting a fixed mold, one surface thereof fixed to the first surface of the frame, and a mobile mold base supporting a mobile mold, the mobile mold base held by the holding mechanism so that the mobile mold base moves closer to and away from the fixed mold base. The holding mechanism includes a rail fixed to the first surface, and a guide fit on the rail in such a way that the guide moves on the rail while the guide is fixed to the mobile mold base. The mobile mold base is supported by the holding means without using a tie bar, and cantilevered on the first surface via the holding mechanism.

Mold device

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.

Mold-making device and mold-making method

Sand for a casting mold including sand, a binder, and an inorganic compound particle having poor water solubility and generating a gas, which is at least one of water vapor or carbon dioxide gas, by heat from a molten metal.
