摘要： A casting mold is provided with a cavity portion and an overflow portion, and the overflow portion is connected to a gas flow path (suction path). A valve (an on-off valve, a shut-off valve) is provided between the gas flow path and the overflow portion. A heating method for a casting mold includes a step of setting the pressure in the cavity portion to a second pressure by sucking gas in the overflow portion and in the cavity portion while the valve is kept open for a second time period shorter than a first time period during casting. The heating method further includes a step of heating the casting mold by supplying molten metal into the cavity portion set at the second pressure, and solidifying the molten metal.

摘要： A casting mold includes a cavity portion, a gas flow path, and a shut-off valve capable of blocking the gas flow path. An inspection method for the casting mold includes: a step of, when the casting mold is cold, supplying air having a predetermined pressure into the gas flow path while the shut-off valve is closed, and thereafter stopping supply of the air; a step of acquiring a cold time pressure reduction rate of the air in the gas flow path after the supply of the air is stopped; and a step of determining whether the cold time sealing performance of the shut-off valve is good, based on the cold time pressure reduction rate.

摘要： A system (5) and method (800) for unit cell casting of titanium or titanium-alloys is disclosed herein. The system (5) comprises an external chamber (45), a crucible (10) positioned within the external chamber (45), an induction coil (15) positioned around the crucible, an internal chamber (40) positioned within the external chamber (45), and a mold (30) positioned within the internal chamber (40). The external chamber (45) is evacuated and a pressurized gas is injected into the evacuated external chamber (45) to create a pressurized external chamber (45). An ingot (20) is melted within the crucible utilizing induction heating generated by the induction coil (15). The internal chamber (40) is evacuated to create an evacuated internal chamber (40). The titanium alloy material of the ingot (20) is completely transferred into the mold (30) from the crucible (10) using a pressure differential created between the external chamber (45) and the internal chamber (40).

摘要： Molten metal M is raised to the vicinity of a gate 11 of a cavity 9C by increasing the pressure in a holding furnace 5 with gas, and thereafter the cavity 9C is filled with the molten metal M by decreasing the pressure in the cavity 9C by suction and further increasing the pressure in the holding furnace 5. Thereafter, the decompression of the cavity 9C is stopped after a preset filling time, and the compression of the holding furnace 5 is stopped when solidification of the molten metal M is completed. In this way, the suction is minimized, and it becomes possible to employ a simple decompression part 14. A reduction in equipment cost and production cost is thereby achieved, and a reduction in casting cycle time is also achieved.

摘要： In a vacuum casting method, a molding cavity is reduced in pressure to a vacuum, and when a gate is opened, a molten metal which has been raised to a molten metal retaining dome is charged into the molding cavity at a high speed. When a portion of a molten metal held in a molten metal holding furnace is raised to the molten metal retaining dome via a stalk, (1) the rising speed of a portion of the molten metal is set at 5-10 cm/sec, or (2) the rising speed is varied between an early stage of the rising motion and a later stage of the rising motion. In the latter method, the rising speed at the early stage of the rising motion is set at a speed higher than 10 cm/sec, while the rising speed at the later stage of the rising motion is set at 5-10 cm/sec. Due to the rising speed control, air involvement by the rising molten metal is effectively prevented.
