A casting mould comprising: an inorganic or refractory mould, wherein the mould is configured to receive feedstock; wherein the feedstock is configured to be heated in situ. A reusable mould, reusable susceptor, and/or release agent may be incorporated. Method of manufacturing a mould, and casting a part employing 5 in situ heating, are also provided.

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.

A mold package for forming a cast device such as an engine block is described. The mold package includes a profiled chill and a mold core assembly that is disposed on the profiled chill. The mold core assembly defines a plurality of bulkheads of the engine block. The profiled chill includes a first chill portion having a second chill portion and a plurality of third chill portions arranged thereon, wherein the second chill portion is a semicylindrical element. The third chill portions are arranged to be adjacent to the plurality of bulkheads of the engine block.

The application provides a cooling water channel for a casting mold. The cooling water channel adopts a sealing structure in which a water channel insert, a sealing cover plate and a metal corrugated sealing ring are matched with each other, wherein a bottom surface of the metal corrugated sealing ring is corrugated or two side walls of the metal corrugated sealing ring are corrugated, and the sealing cover plate is pressed to enable the metal corrugated sealing ring to generate elastic deformation, so that corrugations on the two side walls of the metal corrugated sealing ring and a side wall of the water channel form multi-point contact or the bottom surface of the metal corrugated sealing ring expands to make the side walls of the metal corrugated sealing ring in tight contact with the water channel to achieve a water channel sealing effect.

A cooling system for a molding tool or molding machine includes a high-performance coolant, multiple cooling circuits with different coolants flowing along each circuit, and/or a self-contained cooling circuit. The high-performance coolant can include a metallic component in various forms, including a liquid phase metal form. Newly recognized coolant characteristics such as volumetric heat capacity (C.sub.v) can be used to identify suitable coolants. High-performance coolants can be used to reduce molding process cycle times, to spatially equalize the cooling rate of the molding material among different sections of the mold cavity, and/or to help cool other parts of the tool or machine such as a runner or an injection sleeve.

In a casting device, positions of discharge ends discharging cooling gas, of respective gas supply nozzles are adjusted in response to movement of a mold. This makes it possible to stably achieve high cooling performance for the mold by blowing of the cooling gas. To adjust the positions of the respective discharge ends, the gas supply nozzles are advanced or retreated, or are expanded or contracted. Further, a cooling chamber may include a radiation cooling portion that cools the mold by radiation, and the radiation cooling portion is disposed below the gas supply nozzles that are provided directly below a heat shielding body partitioning a heating chamber and the cooling chamber.

A casting apparatus for manufacturing a cast product from molten metal includes a molten metal and a cooling portion. The molten metal contacts a surface for contact with the molten metal. The cooling portion forms a cooling flow passage. The cooling flow passage is configured to cool the molten metal contacting surface. At least a part of an inner surface of the cooling flow passage is constituted of a welding portion formed by welding, the welding portion sealing the cooling flow passage. The welding portion is constituted such that an exposure to the molten metal becomes equal to or less than a predetermined ratio with respect to an area of the welding portion constituting the inner surface of the cooling flow passage.
