A casting device includes a bore formation core and a water jacket formation core. When a cavity is formed, gas existing in a space between both cores is suctioned through a flow path formed in the bore formation core under operation of a suctioning device. When the bore formation core is viewed from a side, this flow path exists above a virtual axial line that passes a center of the bore formation core and extends along a longitudinal direction of the bore formation core.

A venting device for venting a casting mold in the form of a chill vent having two mold halves which oppose each other and are complementary to each other in form and function, each mold half having a plurality of elevations and indentations in the areas facing each other and the elevations of one mold half engaging with the indentations of the second mold half, and a gap being formed between the two mold halves when the mold halves are placed on each other, air and surplus molten material flowing out through said gap when the casting mold is being filled, the gap having, in the flow direction of the molten material, a saw-toothed course having several sawtooth portions disposed in a row in the flow direction, each sawtooth portion having a leading edge inclined in the flow direction and a trailing edge inclined against the flow direction.

A device (10) for producing die-cast components with a die-casting mold (12) and a discharge device which is provided for controlled evacuation of a mold cavity. The device (10) includes at least one vacuum unit (18) and at least one suction line (20) which connects the die-casting mold (12). The suction line (20) terminates at a mold vacuum valve (21) in the mold cavity. The device (10) is connected to a central control system (1). A filter module (2) is inserted in the at least one suction line (20). The filter module (2) contains at least one filter, a moisture sensor, and a pressure sensor.

A die casting machine is provided with a movable platen for holding a movable mold, a stationary platen for holding a stationary mold, and tie bars inserted into insertion holes provided in the movable platen and the stationary platen, the movable platen being arranged so as to be capable of advancing to and retreating from the fixed platen along the tie bars. A hollow section is provided in at least one of the movable platen and the stationary platen.

A vacuum system for a die casting mold, which forms vacuum inside a cavity formed between a fixed mold and a movable mold, includes: a ventilation assembly disposed between the cavity and a vacuum pump and mounted between the fixed mold and the movable mold and configured to decrease a flow rate of molten metal when the molten metal filled in the cavity flows in; and a vacuum pump forming the vacuum inside the ventilation assembly.

A vacuum die casting method may include: coupling a fixed die and a movable die to each other; closing a molten metal pouring hole formed in a sleeve using an injection plunger operated in the sleeve, which is formed on a lower side of the fixed die or the movable die; performing vacuum decompression in a cavity formed between the fixed die and the movable die using a vacuum decompression device connected to chill vent blocks provided on upper portions of the fixed die and the movable die; supplying oxygen in the cavity using an oxygen supply device connected to the chill vent blocks after completing the step of performing vacuum decompression; and supplying a molten metal to the cavity through the molten metal pouring hole.

Apparatus and methods for creating cast metal objects in space and other environments. Molds are created using additive manufacturing and are injected with a castable metal having a melting point lower than a mold melting point. In some aspects, the additive manufacturing device and the metal casting unit are contained in the same unit.

A vacuum sensor system includes a vacuum pump, vacuum tank, solenoid valve, filters, vacuum block, sensors, and a central processing unit (CPU). The vacuum sensor system monitors the performance of a vacuum system connected to a high pressure die casting machine to ensure that the components cast in the mold or die will have a greater yield of acceptable parts. More specifically, the vacuum sensor system uses sensors to monitor and analyze the vacuum pressure at multiple locations to determine which components are clogging and causing a loss of vacuum pressure in the system. When the CPU detects an anomaly in the pressure, the CPU provides notification in one or more of the following ways: sending a command to shut down the die casting machine; visual notification on the screen of the CPU; an audible warning signal; a visual notification on a semaphore installed on the machine; and/or an electronic notification to one or more users via email, text, or other form of telecommunication.

The casting of metals or salt and products made by casting metals or salts are described. For example, a method for casting metals or salts includes evacuating a mold that is pressurized with an inert gas and coupled to a pressurized source of molten metal or salt, wherein the pressurization of the source is sufficiently high to drive the molten metal or salt into the mold in response to the evacuation.
