摘要： A directional solidification casting method includes fluidly coupling a feed line conduit with a source of molten metal and with a directional solidification mold at a gating. The mold has an interior chamber with a shape of an object to be cast using directional solidification in a growth direction. The feed line conduit is fluidly coupled with the gating in a downward direction oriented at an angle that is closer to the growth direction of the mold than to another direction that is perpendicular to the growth direction of the mold. The method also includes positioning a downstream portion of the feed line conduit below the gating, directing the molten metal into the mold via the feed line conduit, and casting the object in the mold using directional solidification.

摘要： An object is to provide a casting device that is capable of maintaining depressurization in a cavity. A casting device (1) is configured to move an extrusion pin (3), slidably inserted in an insertion hole (29) formed in a mold (2), into a cavity (20) in the mold to release a casted product. The casting device (1) includes a depressurized space creator (4) configured to create a depressurized space (40) on a reverse side of a cavity surface to define the cavity (20). The depressurized space creator (4) covers an opening of the insertion hole (29) to maintain depressurization in the cavity (20).

摘要： A mould for use in manufacturing a single-crystal component by metal casting and epitaxial growth, includes a cavity in which the component is to be formed and a housing having an elliptical cross-section in which a single-crystal seed is disposed, the seed having an elliptical cross-section defined by a minor axis and by a major axis, the housing being in fluid communication with the cavity via an opening of circular cross-section through which molten metal is to flow, the single-crystal seed and the opening being centred on the same vertical axis, in which the minor axis and the major axis of the cross-section of the seed are oriented as a function of the secondary crystallographic orientations of the single-crystal forming the single-crystal seed.

摘要： A mold unit (30) defines an elongate cavity (70) and has an injection inlet port (90) for a viscous material at one end of the cavity and an injection outlet port (92) at the other end of the cavity. The mold unit includes a gas vent formed by a gap (G2) between two parts of the mold unit. The gap extends continuously or intermittently in the length direction of the the mold unit, while penetrating through the mold unit in the thickness direction such that it provides fluid communication between an interior space and an exterior space of the cavity. The gap is shaped such that, although gasses pass through, the viscous material does not pass due to fluidity resistance of the viscous material resulting from its viscosity. As a result, the gas vent acts to block leakage of the viscous material while permitting degassing of the viscous material.

摘要： A gas suction device of a casting mold includes an overflow portion, a suction path, and a shut-off valve. The shut-off valve includes a housing section for housing a valve element. An upstream-side housing portion of the housing section has an arc-shaped outer peripheral edge. The overflow portion includes an introduction path which is continuous with the upstream-side housing portion and guides gas to the upstream-side housing portion. At a predetermined location on the outer peripheral edge, the introduction path is connected to the upstream-side housing portion along the tangential direction of the outer peripheral edge.

摘要： The application belongs to the technical field of a casting mold and provides a side mold and a low-pressure hub casting mold. Channels of a cooling loop are processed in a back cavity of a side mold frame, a distance between the channels along a solidification direction of a casting gradually increases, and a cooling medium flows along the cooling loop, the ability of taking away heat changes from strong to weak, and a larger temperature gradient of the side mold may be formed by superposition with a temperature gradient formed by the thickness of the side mold.
