A cast-metal object is cast by using a casting device (10) including a mold structure (5) for forming a casting space capable of filling molten metal; and a runner (1) provided separately from the mold structure (5) for supplying molten metal into the casting space in the mold structure (5) by connecting the runner to the mold structure (5), wherein the runner (1) has a dividable structure, and the mold structure (5) has an assembly structure of a plurality of members.
Claims5
A casting method of casting a cast-metal object which comprises:
- casting a cast-metal object by using a casting device including:
- a mold structure for forming a casting space allowing molten metal to be filled in, and
- a runner provided separately from the mold structure for supplying molten metal into the casting space in the mold structure by being connected to the mold structure, wherein:
- the runner has a dividable structure, and the mold structure has an assembly structure of a plurality of members;
- at least a partial member constituting the mold structure is made of destructive material;
- and
- the partial member made of the destructive material has a through hole for guiding a portion of molten metal moving from the runner to the casting space of the mold structure and for introducing molten metal from a different position from the runner to the casting space.
