Abstract: A die casting furnace system includes a die casting holding furnace unit defining a cavity for holding a molten metal. A dosing unit is disposed within the cavity and defines a dosing area disposed in fluid communication with the cavity for receiving the molten material during a pressurization of the cavity. The cavity of said die casting holding furnace unit has a first storage capacity and the dosing area of said dosing unit has a second storage capacity being less than the first storage capacity. An ultrasonic unit is operably coupled with the finitely sized dosing area and is configured to introduce vibration into the received molten material for facilitating the removal of gases from the received molten material. The treatment of the finitely sized dosing area with the ultrasonic unit leads to improved metal cleanliness and accuracy that is not achievable with prior art systems.

Abstract: A low pressure die-casting machine has a ladle unit, a molten metal pressurizing unit, a switching unit, and a controller. The ladle unit has an intake/discharge port with a cross-sectional area in a range of from 20 to 80 mm.sup.2 so as to be capable of successively supplying the molten metal to a desired location. The molten metal pressurizing unit is switchable between two positions. One position is for selectively supplying compressed air to the ladle to positively discharge the molten metal from the ladle through the intake/discharge port. The other position is for selectively isolating the ladle in order to retain the molten metal therein. The switching unit is connected between the molten metal pressurizing unit and the ladle. It is switchable between first and second change-over positions. The first change-over position is for providing fluid communication between the ladle and the molten metal pressurizing unit. The second change-over position is for providing fluid communication between the ladle and the atmosphere. The controller is connected to the molten metal pressurizing unit for selectively driving the molten metal pressurizing unit. The controller is also connected to the switching unit for driving the switching unit.

Abstract: The invention relates to a control apparatus for an automatic pouring furnace. According to the invention, the control apparatus, for example, a microcomputer, reads from a memory to regulate shot pressure and time periods for application of the shot pressure to effect a pouring operation as a function of the particular mold to be filled. Thus, a single furnace can be regulated automatically to fill a plurality of molds which, while limited in number, are various in kind.

Abstract: A holding or smelting furnace for discharging measured quantities of molten metal includes a furnace wall defining a furnace chamber adapted to contain molten metal having an upper free melt level, and at least one melt outlet channel extending from the furnace chamber through the furnace wall at a level below the free melt level. A sliding gate valve is mounted on the furnace wall at the outlet channel and is movable between a closed position blocking the outlet channel and an open position unblocking the outlet channel. Control structure maintains the free melt level at a constant level within the furnace chamber, and thereby maintains the hydrostatic pressure of the molten metal within the furnace chamber at a constant value during discharge of the molten metal. Regulating structure is operable independently of the operation of the control structure and moves the sliding gate valve between the closed and open positions thereof at a predetermined timed cycle.

Abstract: A process for controlling a vessel for a repeated pouring of a liquid under low pressure into blind sand moulds. The process comprises after each pouring, lowering the liquid in the pouring tube only to a level which is equal to or substantially equal to a constant predetermined level in the vicinity of the outlet of the tube. According to the invention, the level of the liquid in the tube and the pressure of the driving gas prevailing in the vessel are measured directly and the inlet and exhaust of the driving gas are controlled as a function of these measurements so as to ensure, for all the pourings, a pressure rise time and a pressure drop time which are predetermined and substantially constant. A device is described for carrying out this process.
