A metal mold casting machine for a casting apparatus with which the worker can easily carry out his or her work, such as setting a core, cleaning a mold, taking out castings, etc. The casting apparatus includes a turntablethat is rotatable in a horizontal plane, and a number of metal mold casting machinesthat are placed on an upper side at the periphery of the turntable. Each of the machineshas an opening and closing mechanismfor a mold. A pouring basin, from which molten metal is poured into the mold, is mounted on the casting machine, and moves over the mechanismbetween the peripheral side and the side toward the rotation axis of the turntable. The pouring basinis moved to the peripheral side when molten metal is poured into the mold. It is then moved to the side toward the rotation axis of the turntablewhen work such as taking out of a casting from the mold is carried out.

Metal mold casting machine of a casting apparatus

A low-pressure casting apparatus is provided wherein molten metal can be precisely cast even into a casting mold of a comparatively small capacity, not to mention a casting mold into which a large capacity of molten metal is to be cast, and wherein the casting mold is accurately pressurized. The casting mold, into which a large capacity of molten metal is to be cast, can be cast by connecting at least two crucibles to the casting mold via at least two stalks and at least two connection mechanisms, and by connecting at least two molten-metal holding furnaces to the pressurized-gas supply means via at least two connecting mechanisms, after the pressure chambers of the holding furnaces are made to communicate with each other via the communication mechanisms. A casting mold of a relatively small capacity can also be cast by connecting one of the crucibles to the mold via one of the stalks and one of the connecting mechanisms, and by connecting one of the holding furnaces to the pressurized-gas supply means via one of the connecting mechanisms.
