があった。``Conventional technology'' Conventionally, shell molds have been used in casting operations that require precision, but in the case of casting operations that require precision, shell molds have been used. A pouring hole is provided in the mold located at one end, and when molten metal is poured into the mold row from this pouring hole, the air inside the mold expands due to the high heat of the molten metal, and the resin, etc., which is the solidifying agent of the mold, burns. The gas created back pressure in the mold, which slowed the flow of molten metal and could cause casting defects such as blowholes.

とができる。Next, to explain the operation of this embodiment, a plurality of molds (1) having a connecting runner (2) and a cavity (3) continuous to the runner are fixed by solidifying using an additive. A mold row (8) is formed by forming a mold row (8), and a pouring port (9) is provided connected to the mold row runner (2). The plug αO is fitted, and the suction means (2) and the combustion means (2) are connected through this plug 00.
) is connected to the pipe (1) having a suction means (2).
, and the connected runner (
2) With a unidirectional flow of 9 air inside, open the spout (
Pour the molten metal from step 9). When this molten metal enters the mold (1), combustion gas such as resin is generated, and since the molten metal enters the pouring port (9) side, it is difficult for the gas to be discharged into the atmosphere. Since the gas is sucked into the part, the molten metal from the pouring port (9) is not affected by back pressure and can smoothly enter the connecting runner and the product cavity.
