摘要： An apparatus for the die casting in the semisolid state of objects made of brass, bronze, alloys of aluminum, magnesium and light alloys and the like, includes an upper die part adapted to be mated with a lower die part, the mating between the upper die part and the lower die part forming a casting cavity, a furnace being arranged below the lower die part and being provided with a duct for feeding liquid metal which connects to the casting cavity. The upper die part is provided with a cavity in which a forging piston can move freely, the piston accommodating internally a flow control plunger, and having, between the upper die part and the lower die part, circumferentially around the part to be cast, a vacuum channel connected to the casting cavity by at least one venting channel.

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： An apparatus and method is disclosed for forming an item in a mould using a casting process, typically a counter gravity casting system. Heating assembly, transfer assembly and mould filling assembly can be used in combination. The transfer assembly includes apparatus and method for removing sedimentation from the liquid metal and/or metal alloy received from the heating assembly and extracting the same prior to the metal and/or metal alloy reaching the mould filling assembly at which the same is supplied to fill a cavity of a mould and which, once filled, can be slid to a location to cool and thereby make available the mould filling assembly for the next mould to be filled. This apparatus and method provide an efficient, high throughput system, along with high quality cast items.

摘要： The present invention relates to a casting mold for a metal sheet by drawing molten metal into a mold cavity and cooling the molten metal, and the casting mold according to the present invention includes: a support portion at an upper side on which molten metal is disposed or a solid metal is placed and melted; a mold cavity at a lower side in which the metal sheet is formed as the molten metal is drawn from the support portion while filling the mold cavity and cooled; and a passageway through which the molten metal is drawn into the mold cavity from the support portion, in which the mold cavity includes a first surface at the upper side which communicates with the passageway, and a second surface at the lower side which faces the first surface, a plurality of suction portions for drawing the molten metal are formed in the second surface and extended downward from the second surface, the suction portions are connected to a vacuum source and configured to draw the molten metal by suctioning air from the mold cavity, and a blocking member, which is in contact with the second surface or the suction portions to prevent a leakage of the molten metal and allow an air flow, is disposed on the suction portions in the mold cavity.

摘要： A counter-gravity casting method and apparatus in which the mold is held stationary and the crucible is moved generally laterally from a melt chamber to a fill chamber positioned below the mold with respect to gravity. A casting chamber is located generally above the fill chamber with respect to gravity. The method and apparatus utilize separate chambers for melting and casting in which the pressure in each chamber can be varied relative to each other in order to introduce molten metal into the mold.

摘要： A casting device includes: a split mold for forming a cavity, including a lower mold, a middle mold that slides in a horizontal direction on the lower mold and an upper mold; a split case for forming a chamber, including a lower case to which the lower mold is attached and an upper case to which the upper mold is attached; a chamber suction device that reduces a pressure at least in the chamber through a chamber pipe that is connected to the chamber and extends to an outside of the chamber; and a cavity suction device that reduces a pressure in the cavity through a cavity pipe that is connected to the cavity and extends to the outside of the chamber. The cavity and the chamber are formed when the middle mold is closed on the lower mold and the split case is closed.

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).
