Definitions

  • the invention relates to a casting device for low or counter pressure casting according to the preamble of claim 1.
  • the invention further relates to a system for producing a workpiece by means of low-pressure or counter-pressure casting.
  • Systems with a casting device in particular for casting under a pressure generated by a gas phase, are used in foundry technology, in particular for the production of castings with high physical and mechanical characteristics, in particular from light metal alloys.
  • the actual casting process takes place both in the low-pressure casting process and in the counter-pressure mold casting process with the aid of a riser pipe through which the melt is conveyed upwards into the mold.
  • the pressurization of the melt in the furnace to convey the melt up into the mold is brought about by a pressure difference in the counter-pressure mold casting process, in that the gas pressure in the mold is reduced somewhat. This creates an overpressure in the casting furnace, which is sufficient for the melt to rise into the mold.
  • a casting device of the type mentioned is from the CN 102416460A known. Relevant casting machines are also out of the JP H0252160A , the DE 1583663A1 , the EP 1270116A2 , the CN 203817343U , the WO 2011 / 003396A1 the CN 103962528A known.
  • Another relevant casting device and a system are for example also from the DE102010026480A1 known.
  • the platen by which the lower chamber is separated from the upper chamber, is fixed in place and its position cannot be changed.
  • the furnace is positioned in the lower chamber is raised.
  • a further disadvantage is that two hoists or drives are required in the known solutions, since both the furnace and the upper platen have to be moved. Which also significantly increases the overall height.
  • Another disadvantage of known solutions is that manipulating the mold in the upper chamber is also very difficult.
  • the object of the present invention is to enable an optimal loading of the casting device with a mold as well as an optimal manipulation of the mold. This object is achieved according to the invention with a device of the type mentioned in the introduction by the features of the characterizing part of claim 1.
  • the solution according to the invention considerably simplifies handling and manipulation of the mold, since the space available for manipulating the mold can be changed in a simple manner.
  • the platen can be displaced in a vertical direction.
  • the lower platen Due to the vertical mobility of the lower platen, it can be moved upwards, which increases the space available in the lower chamber for manipulating the furnace. In this way, the furnace can be easily positioned in the chamber and removed again.
  • the lower and the upper chamber can each be hermetically, in particular gas-tight, sealed.
  • the upper and / or lower chamber could also be evacuated or filled with a protective gas.
  • the solution according to the invention saves the second drive for lifting the furnace, as a result of which the overall height can also be significantly reduced.
  • the at least one lower platen has at least one riser pipe for connecting the at least one furnace to the at least one mold.
  • the arrangement of the riser pipe on the lower platen has the advantage that the riser pipe can be lifted by lifting the lower platen, whereby the riser pipe can be removed from the area of the furnace very quickly and the furnace can be replaced very quickly.
  • a lower edge of the riser pipe is raised above an upper edge of the furnace, since the furnace can then be removed from the chamber or inserted into the chamber in a horizontal direction without being impeded by the riser pipe.
  • the mold mounting plate and or furnace plate can have several risers for several mold cavities and or several molds.
  • Another advantageous embodiment is an exchangeable insert in the furnace plate and or mold mounting plate in which the at least one riser pipe is fastened.
  • a further advantageous embodiment when using at least one riser pipe is the design of the interchangeable insert as a distributor for the casting of several mold nests or the casting of a mold over several gates. It is advantageous if this distribution cavity is made of steel with a ceramic lining. It is also advantageous to have at least one heating element on this distribution cavity in order to keep the aluminum at the melting temperature after casting in order to let the melt run back into the furnace.
  • the upper platen can have holding elements and, where appropriate, media interfaces for the upper part of the mold.
  • the upper mold clamping plate is particularly preferably connected to first connecting elements, the lower mold clamping plate being connected to second connecting elements, wherein each of the first connecting elements is brought into engagement with a corresponding connecting element of the second connecting elements by vertical displacement of the upper mold clamping plate in the direction of the lower mold clamping plate.
  • This variant of the invention has the advantage that the upper platen and the lower platen can be moved together. So by a lifting or lowering movement the upper platen, the lower platen can be raised or lowered. This is advantageous, inter alia, in terms of reducing the drive elements required for the movement of the platen. In addition, the movements of the two platen plates can be synchronized in this way with little effort, which is particularly advantageous when the furnace and / or the mold arranged above it are replaced quickly.
  • each of the first connecting elements forms a positive and / or non-positive closure with the respectively associated second connecting element. If necessary, the closures can be released again and, for example, the upper platen can be moved relative to the lower platen. It is particularly advantageous if one of the connecting elements snaps into the associated other connecting element as soon as one of the two connecting elements is pushed into one another in the other connecting element or the two connecting elements. This enables the lower and the upper platen to be connected very quickly and automatically simply by vertical displacement of the upper platen.
  • the upper platen is connected to actuators for raising or lowering the upper platen.
  • the connection of the upper platen to actuators has the advantage that the upper platen can be moved both with respect to the lower platen and together with it.
  • a movement of the upper platen independently of the lower platen is particularly advantageous when loading the upper chamber with a mold, since the space available for loading the upper chamber can be increased by lifting the upper platen.
  • a mold located in the chamber can be lifted from the upper mold mounting plate in a closed state (upper and lower part connected to one another) and loaded onto a transport carriage using a manipulator.
  • the upper platen can be connected to the upper part of the closed mold.
  • the mold can be connected to the lower platen and, if necessary, the upper part can be detached from the lower part of the mold.
  • a joint movement of the lower and the upper platen is, as already mentioned above, particularly advantageous when loading the lower chamber with an oven and removing it from there.
  • the actuators are designed as piston / cylinder units, in particular as hydraulic cylinders, pistons of the piston / cylinder units being connected to the upper platen and working cylinders of the piston / cylinder units being arranged under the associated pistons and are supported.
  • This arrangement of the piston / cylinder units allows a low overall height to be achieved, since the pistons push the upper platen upwards.
  • the pistons would pull the platen upwards and the cylinders would have to be suspended above the platen, which would increase the overall height.
  • higher forces acting on the pistons can be realized than in an arrangement in which the pistons pull the upper platen upwards, because the force does not affect the entire available cross-sectional area of the piston can only be exercised on an annular surface.
  • a proven embodiment consists in that the four shafts connected to the platen are provided with gearwheels, two of the four shafts running parallel to each other in pairs and axes of two immediately adjacent shafts running perpendicular to one another.
  • An advantageous development of the invention consists in the connection of at least one shaft to an electric drive. This enables the actuators to be supported. It is also advantageous to use the electric drive when lowering as a brake or generator and thus to recuperate the potential energy of the upper platen and / or mold in generative operation. A further advantageous embodiment is the decoupling of the actuators after the mold has been torn open and, for example, the vertical displacement of the platen via the electrical drives and the mechanical synchronization system. The execution of the drives by hydraulic or pneumatic rotary drives is also conceivable.
  • the actuators are controlled by servo-hydraulics.
  • actuators can also be controlled digitally and hydraulically.
  • the upper mold mounting plate can be displaced vertically in guides which are arranged on lateral structures of the casting device, the guides being arranged in the upper chamber.
  • the guides are roller rail guides.
  • the casting device can be a column casting device which has a frame with columns which are arranged between a base plate and a cover structure of the casting device, at least one section of the columns being designed as a guide, on which the mold mounting plate is guided.
  • the cover structure has an x-shaped basic shape. Due to the special design of the cover structure, thermally induced tensions can be reduced particularly well without any constraints, as can be the case with a plate-shaped design of the cover structure. In addition, the x-shaped cover structure enables particularly good accessibility of the casting device from above.
  • At least two casting devices are provided, which are arranged at a distance from one another, with a manipulator for handling workpieces between the casting devices is arranged.
  • the manipulator can carry out further process steps, such as inserting cores, applying size, cleaning the mold and / or testing processes, for example using a camera.
  • the system can have at least one guide on which at least one transport carriage for transferring a furnace is arranged between a preparation station and the at least one casting device.
  • the transport carriage has at least two floors arranged one above the other, a lower floor being provided for transporting the furnace and an upper floor for transporting at least one mold.
  • a system 1 for the production of a workpiece by means of low-pressure or counter-pressure casting shown schematically, has a casting station 2 with two casting devices 10 arranged at a distance from one another. Such a casting station or such casting devices 10 are shown schematically in FIG Fig. 2 and 3 shown.
  • Each of the casting devices 10 has a lower, in particular hermetic, sealable chamber 3 and an upper, in particular hermetic, sealable chamber 5, which are separated from one another by a lower platen 15.
  • the term chamber in this document is to be understood in such a way that it also includes structures with partially or fully opened side walls, as is the case, for example, in the Figures 1 to 3 is shown.

  • the upper platen 12 is slidably mounted in the vertical direction, for example on a base frame of the casting device 10, and with in Figure 3 connected with the reference numeral 17, the first connecting elements.
  • the upper platen 15 can in this case be vertically displaceable in guides 33 which are arranged on lateral structures of the casting device, for example columns, wherein the guides 33 are arranged in the upper chamber 5.
  • the guides 33 can be designed, for example, as roller rail guides or sliding guides.
  • the casting device is designed as a column casting device, at least a portion of the columns can be designed as a guide, on which the platen 12 is guided.
  • the lower platen 15 is in with Fig. 3 connected with the reference numeral 16, second connecting elements.
  • Each of the first connecting elements 17 can be brought into engagement with a corresponding connecting element of the second connecting elements 16 by a vertical displacement of the upper mold mounting plate 12 in the direction of the lower mold mounting plate 15.
  • Each of the first connecting elements 17 forms with the associated second connecting element 16 each have a positive and / or non-positive closure.
  • the lock can be unlocked again, for example electronically controlled, so that the connecting elements 16 and 17 can be released from each other again.
  • the closure can have, for example, an electronically controlled locking mechanism.
  • Fig. 1 discloses that the piston / cylinder units 25 are attached to all four corners of the upper platen 12. However, it is also possible that only a single piston / cylinder unit is provided due to the mechanical synchronization described below. However, it is particularly advantageous if at least two piston / cylinder units are provided.
  • racks 30 are shown inside in the upper chamber, in which gear wheels 32 mounted on shafts 31 engage.
  • the shafts 31 are mounted on the platen 12 in the immediate vicinity of the gears 32. It is advantageous in this embodiment that the force redistribution from a piston / cylinder unit 25 from the connection point of the mold mounting plate 12 via the bearing point and the shaft 31 to the gear wheel 32 onto the rack 30 fastened to the frame of the casting device 10.
  • the gear wheel 32a opposite the gear wheel 32 also engages into a rack 30a and in this way transmits a torsional moment ( Fig. 4 ).
  • the shaft 31 is mounted on mutually opposite bearing points connected to the upper platen 12, the shaft 31 having two gear wheels which interact with two different racks arranged on the frame of the casting device.

  • two piston / cylinder units 25 diametrically opposite one another, two smaller piston / cylinder units 25 a, also diametrically opposed, can be provided.
  • the two piston-cylinder units 25a essentially serve to support the lifting of the platen 12 from a lower basic position.

  • the mechanical synchronization enables a so-called high “pull-off accuracy” (non-misalignment when the tool is torn open).
  • the closing movement of the tool can take place via two of the four piston cylinders, while four piston cylinder units are preferably used for tearing open the tool.
  • the at least one rotating drive can be used to vertically shift the platen or to support the actuators. It is advantageous if the at least one rotating drive can also be operated in generative operation and the energy is recuperated when the platen is lowered.
