Description

caster

The invention relates to a casting device for low- or counter-pressure casting, wherein the casting device has at least one lower chamber for at least one furnace and at least one upper chamber for at least one mold and the upper and lower chambers by at least one lower platen for fixing a lower part of at least a mold are separated from each other. Furthermore, the invention relates to a plant for the production of 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 light metal alloys.

The actual casting process takes place both in the low-pressure casting process and in the counter-pressure Kokillengießverfahren using a riser, through which the melt is conveyed up into the mold.

However, the pressurization of the melt in the furnace to convey the melt up into the mold is brought about in the counterpressure die casting process by a pressure difference by slightly lowering the gas pressure in the mold. This creates an overpressure in the casting furnace, which is sufficient for the melt to rise into the mold.

A casting apparatus and a plant of the type mentioned are known for example from DE102010026480A1. In the known solutions, the platen, by which the lower chamber is separated from the upper chamber, fixed in place and can not be changed in position. To connect the oven to the mold via a riser, the oven is raised after being positioned in the lower chamber. However, this has the disadvantage that on the one hand a very high mass must be moved and this process on the other hand, a quick replacement of a Furnace is relatively time consuming for a new casting process. Another disadvantage is that in the known solutions two hoists or drives are required because both the furnace and the upper platen must be moved. Which also significantly increases the height. Another disadvantage of known solutions is that it also makes manipulation of the mold in the upper chamber very difficult.

The present invention has for its object, an optimal loading of the casting device with a mold and an optimal manipulation of the mold to ermögli- chen.These object is achieved with a device of the type mentioned in the present invention, that the upper chamber an upper, in vertical Direction displaceably mounted mold clamping plate for an upper part of the at least one mold, the upper platen is connected to actuators for raising or lowering the upper platen. 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.

According to an advantageous development of the invention, the mold clamping plate can be displaced in a vertical direction.

Due to the vertical mobility of the lower platen this can be moved upwards, whereby the space available for manipulation of the furnace in the lower chamber is increased. In this way, the oven can be easily positioned in the chamber and removed again. Moreover, it is possible to connect the furnace positioned in the lower chamber to the mold without raising it vertically, by lowering the upper mold plate. It should be noted at this point that the lower and the upper chamber can each be hermetically, in particular gas-tight, sealed. Also, the upper and / or lower chamber may be evacuated or filled with a protective gas. In addition, the solution according to the invention saves the second drive for lifting the furnace, whereby the overall height can be significantly reduced. According to an advantageous variant of the invention, it can be provided that 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 on the lower platen has the advantage that by lifting the lower platen mold the riser can be mithebehoben, whereby the riser very quickly removed from the range of the furnace and the furnace can be replaced very quickly. In particular, it is advantageous in this case if 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 introduced into it in the horizontal direction without being impeded by the riser pipe. Alternatively, for mounting the riser to the lower platen, however, it would also be possible to move the riser separately from the platen.

Furthermore, the mold clamping plate and or oven plate may have a plurality of riser tubes for a plurality of mold cavities and / or a plurality of molds. A further advantageous embodiment is a replaceable insert in the oven plate and or platen in which the at least one riser is attached. A further advantageous embodiment of the use of at least one riser is the execution of the interchangeable insert as a distributor for the casting of several mold cavities or the casting of a mold over several sprues. It is advantageous if this Verteilkavität steel is performed with ceramic lining. Also advantageous is at least one heating element at this Verteilkavität to the

After casting, keep the aluminum at the melting temperature to allow the melt to run back into the furnace.

The upper platen may have holding elements and optionally media interfaces for the upper part of the mold.

Particularly preferably, the upper platen is connected to first connecting elements, wherein the lower platen is connected to second connecting elements, wherein each of the first connecting elements with a corresponding Verbindungsele- element of the second connecting elements by a vertical displacement of the upper platen in the direction of the lower platen engaged is. This variant of the invention has the advantage that the upper platen and the lower platen can be moved together. Thus, a lifting or lowering Movement of the upper platen lift the lower platen lifted or lowered. This is advantageous, inter alia, with regard to reducing the drive elements required for the movement of the platens. In addition, the movements of the two platens can be synchronized with little effort in this way, which is especially advantageous in the case of a rapid replacement of the furnace and / or the mold arranged above it.

With regard to a reliable connection of the upper and lower platen, it is particularly advantageous if 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 engages in 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 allows a very quick and automatic connection of the lower and the upper mold clamping plate solely by a vertical displacement of the upper mold mounting plate.

According to an advantageous embodiment of the invention, it may be provided that 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 this. A movement of the upper platen independent of the lower platen is especially in a Be-loading the upper chamber with a mold advantage, since by raising the upper platen of the available space for charging the upper chamber can be increased. Thus, a mold located in the chamber in a closed state (upper and lower part connected to each other) are lifted from the upper platen and loaded by means of a manipulator on a transport carriage. When loading the upper chamber, the upper platen can be connected to the upper part of the closed mold. By lowering the upper platen, the mold can be associated with the lower platen and be solved in case of need, the upper part of the lower part of the mold. A common movement of lower and upper platen is as already mentioned above, especially with regard to the loading of the lower chamber with an oven and its removal from there an advantage. In a particularly favorable variant of the invention it can be provided that the actuators are designed as piston / cylinder units, in particular as hydraulic cylinders, with pistons of the piston / cylinder units connected to the upper platen and working cylinder of the piston / cylinder units arranged under the respectively associated pistons and supported. By this arrangement, the piston / cylinder units a low height can be realized because the pistons push the upper platen upwards. In another arrangement, the pistons would pull the platen up and the cylinders would have to be placed over the platen hanging, which would increase the height. Also, in this variant of the invention higher forces acting on the piston can be realized than in an arrangement in which the pistons pull the upper platen upwards, the case is because the force on the entire available cross-sectional area of the piston and not can only be exercised on an annular surface. In a preferred variant of the invention, it may be provided that the casting device has an actuator interacting with and connected to the upper platen means for transmitting a torque.

According to an advantageous development, it can be provided that the means for transmitting the torque have at least one toothed rack arranged on a frame of the casting device and at least one toothed wheel cooperating with the at least one toothed rack and at least one shaft connected to the toothed wheel for transmitting a torque.

In addition, it has proved to be advantageous that the at least one shaft is mounted on opposing bearing points connected to the upper platen, wherein the shaft has two gears which cooperate with two different arranged on the frame of the casting rack. A proven embodiment is that the four associated with the platen shafts are provided with gears, with two of the four waves in pairs parallel to each other and axes of two immediately adjacent waves perpendicular to each other.

An advantageous development of the invention consists in the connection of at least one shaft with an electric drive. This allows the actuators to be supported. It is equally advantageous to use the electric drive when lowering as a brake or generator and so recuperate the potential energy of the upper platen and / or mold in the generative operation. A further advantageous embodiment is the decoupling of the actuators after a tearing operation of the mold and the egg bie spi ice continue the vertical displacement of the platen on the electric drives and the mechanical Syncronisationssystem. Also conceivable is the design of the drives by hydraulic or pneumatic rotary actuators.

In order to enable a very precise control, it can be provided that the actuators are servohydraulically controlled.

In addition, the actuators can also be controlled digitally hydraulically.

In order to realize a low overall height and a compact construction, it can be provided that the upper platen can be displaced vertically in guides, which are arranged on lateral structures of the casting device, wherein the guides are arranged in the upper chamber.

To be particularly advantageous, it has been found, when the guides are roller rail guides.

According to a further advantageous embodiment, the casting device may be a column casting device having a frame with columns, which are arranged between a base plate and a cover structure of the casting device, wherein at least a respective portion of the columns is formed as a guide on which guided the platen is. It has proved to be particularly advantageous if the cover structure has an x-shaped basic shape. Due to the special design of the cover structure thermally induced stresses can be broken down particularly well, without causing constraints, as can be the case with a plate-shaped design of the cover structure. In addition, the x-shaped cover structure allows a particularly good accessibility of the casting device from above.

The abovementioned object can also be achieved, according to the invention, by means of a system of the type mentioned at the beginning, in that it has at least one casting device according to one of claims 1 to 17.

To increase the productivity of the system, it may be provided that at least two casting devices are provided, which are arranged at a distance next to each other, wherein between the casting devices, a manipulator for handling workpieces is arranged. In addition, the manipulator can perform other process steps, such as inserting cores, application of sizing, cleaning of the mold and / or test procedures, for example by means of a camera. Furthermore, the system may comprise at least one guide on which at least one transport carriage for transferring a furnace between a supply station and the at least one casting device is arranged.

Particularly advantageous in terms of production time, it is when the transport carriage has at least two floors arranged above one another, wherein a lower floor for the transport of the furnace and an upper floor for transport of at least one mold is provided.

For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

In each case, in a highly simplified, schematic representation:

Fig. 1 is a perspective view of a system according to the invention; Fig. 2 is a front view of a casting station of the apparatus of Fig. 1;

3 is a side view of the casting station of FIG. 2.

Fig. 5 is a plan view of the casting apparatus of Fig. 4;

Fig. 6 is a side view of the pouring apparatus of Fig. 4 and

7 is a front view of the pouring apparatus of FIG. 4.

By way of introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component names, wherein the disclosures contained in the entire description can be mutatis mutandis to the same parts with the same reference numerals or component names. Also, the location information chosen in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and these position information in a change in position mutatis mutandis to transfer to the new location.

The plant 1 shown schematically in FIG. 1 for producing a workpiece by means of low-pressure or counter-pressure casting has a casting station 2 with two casting devices 10 arranged at a distance from one another. Such a casting station or casting devices 10 are shown schematically in FIGS. 2 and 3. Each of the pouring devices 10 has a lower, in particular hermetically, sealable chamber 3 and an upper, in particular hermetically, sealable chamber 5, which are separated from one another by a lower platen 15. It should be noted at this point that the term "chamber" in this document is to be understood as meaning also structures with partially or completely opened side walls, as shown for example in FIGS. 1 to 3. It should also be noted that the terms "mold" and "tool" are used synonymously in this document. The mold clamping plate 15 can be designed to be displaceable in a vertical direction. For example, the mold mounting lath can be mounted displaceably on a base frame of the casting apparatus 10 in the vertical direction. In the lower chamber 3, a furnace 4 can be arranged with melt. In the upper chamber 5, a mold, for example, approximately horizontally divided mold can be arranged, this one in Fig. 2 schematically indicated and provided there with the reference numeral 22 lower part, which can be arranged on the lower platen 15, and an upper part, not shown, which can be arranged on an upper platen 12 may have. The upper platen 12 may have interfaces 13 and 11, for example, brackets and media connections for the upper part of the mold, in particular for swiveling the upper part for better accessibility by an operator. In the region of the lower platen 12, for example, a traction device 14 called core pull can be provided for changing the position of a former.

The upper platen 12 is slidably mounted in the vertical direction, for example, on a base frame of the casting apparatus 10 and connected to the first connecting elements identified by the reference numeral 17 in FIG. The upper mold clamping plate 15 can in this case be vertically displaceable in guides 33 which are arranged on lateral structures of the casting device, for example columns, whereby the guides 33 are arranged in the upper chamber 5. The guides 33 may be formed, for example, as roller rail guides or sliding guides. If the casting device is designed as a column casting device, at least one respective section of the columns can be formed as a guide, on which the mold clamping plate 12 is guided.

The lower platen 15 is connected to in Fig. 3 by reference numeral 16, second connecting elements. Each of the first connection members 17 may be engaged with a corresponding connection member of the second connection members 16 by vertically displacing the upper form platen 12 toward the lower platen 15. Each of the first connecting elements 17 forms Det with each associated second connecting element 16 each have a positive and / or non-positive closure. The closure can, for example, electronically controlled, be unlocked again, so that the connecting elements 16 and 17 can be released from each other again. The closure may, for example, have an electronically controlled locking mechanism.

Fig. 1 discloses that at all four corners of the upper platen 12, the piston / cylinder units 25 are mounted. However, it is also possible that due to the mechanical synchronization described below, only a single piston / cylinder unit is provided. However, it is particularly advantageous if at least two piston / cylinder units are provided.

According to FIG. 2 and FIGS. 4 to 7, 5 racks 30 are shown on the inside in the upper chamber, in which toothed wheels 32 mounted on shafts 31 engage. The shafts 31 are mounted on the platen 12 in the immediate vicinity of the gears 32. An advantage of this embodiment, the force transfer of a piston / cylinder unit 25 from the connection point of the platen 12 via the bearing point and the shaft 31 to the gear 32 on the attached to the frame of the casting device 10 rack 30. The gear 32 opposite gear 32a also engages a rack 30a and thus transmits a torsional moment (FIG. 4).

The shaft 31 is mounted on opposing bearing points connected to the upper platen 12, the shaft 31 having two gears which interact with two different racks arranged on the frame of the casting device.

As can be seen from FIG. 6, four shafts 31 connected to the platen 12 are provided with toothed wheels 32, 32a, wherein in each case two of the four shafts 31 run in pairs parallel to one another and axes of two directly adjacent shafts 31 run perpendicular to one another.

When traveling up and down with a piston / cylinder unit 25, the opposing gear 32a moves with it and moves over the other bearing point of the gear 32a, the For- platen 12 with. As a result, the force of a piston / cylinder unit 25 can at least partially be transferred to another piston / cylinder piston unit 25. Particularly in the case of non-symmetrical tearing forces, which act on the at least one tool, a synchronization and minimized misalignment of the platen 12 is thereby ensured. An advantage of this embodiment is that the guide distance of the upper platen 12 can be reduced without causing jamming on the guides 33 of the platen 12.

For multiple tools, the resulting tearing force is not centered for opening the tools, resulting in a different load on the four cylinder / piston units.

By the above-mentioned power rearrangement, the piston / cylinder unit 25 can be made more energy efficient.

An advantageous further development consists in using only two diametrically opposed piston / cylinder units 25 and / or the piston / cylinder units 25 of different dimensions.

According to FIG. 6, two diametrically opposed piston / cylinder units 25, for example, may be provided with two smaller, likewise diametrically opposite, piston / cylinder units 25a. The two piston-cylinder units 25a serve essentially to support a lifting of the platen 12 from a lower basic position.

A further advantageous embodiment for supporting the synchronization of the piston / cylinder units 25 is the use of the control of the piston / cylinder units 25 by a servo-hydraulic, whereby the efficiency is significantly improved. An inventive design of the servo-hydraulic is the control by volume flow dividers in the hydraulic supply line of the piston / cylinder units. Another characteristic is the control of the piston / cylinder units via a digital hydraulic system. In this method according to the invention, the piston hydraulic cylinders are each fed via pumping elements with a precisely defined volume content which hardly deviates from one another. A pump content represents an "(oil) increment", causing the Synchronization of the piston-cylinder units is ensured by equal volume contents in the supply. Occurring sum tolerance errors and possibly leaks are kept cyclically low by resetting in the basic position. As a reference point for a reset, for example, the lowest basic position of the upper mold clamping plate can be selected.

Due to the mechanical synchronization, a so-called high "extraction accuracy" (non-skewing when the tool is torn open) can be achieved The closing movement of the tool (the mold) can take place via two of the four piston cylinders, while preferably four piston-cylinder units are used to rupture the tool.

By a not shown at least one rotating drive, in particular gear motor, which cooperates with the mechanical synchronization, which can be the vertical

Relocation of the platen made or support the actuators. It is advantageous if the at least one rotating drive can also be operated in generative operation and thus the energy is recuperated when lowering the platen. According to the embodiment shown in Fig. 3, a second connecting element 6 is designed as a pin and the associated first connecting element 17 as a lock. By lowering the upper platen 12 in the direction of the lower platen 15 of the pin snaps into the castle, such as an electromechanical lock, and the upper platen 12 and the lower platen 15 are connected together, so that the lower platen 15 by a movement of the raised upper platen 12 and can also be lowered again.

The upper platen 12 may be connected to actuators 24 for raising or lowering the upper platen 12. In the illustrated embodiment, the actuators 24 are designed as piston / cylinder units, in particular as hydraulic cylinders.

Pistons 26 of the piston / cylinder units are in this case connected to the upper platen 12. Working cylinder 25 of the piston / cylinder units are arranged and supported under the associated pistons 26, for example on a frame of the casting device 10. According to Fig. 1, the casting apparatus 10 may be formed as a column caster, which has a frame with columns 27 which between a base plate 28 and a

Deck structure 19 of the casting apparatus 10 are arranged. The cover structure 19 has an x-shaped basic shape in the illustrated embodiment. A casting apparatus with the cover plate shown in Fig. 1 is an optionally independent embodiment of a casting apparatus, which may also be realized independently of the arrangement of a movable lower mold plate 15 and the other essential features of the subject invention.

The furnace 4 provided with the melt and the mold cavity formed by the two mold parts in the closed state are interconnected by means of a riser 23 as shown in FIG. 2, which can be mounted on the lower mold mounting plate 15. The riser 23 follows in the illustrated embodiment, a movement of the lower mold mounting plate 15th

Between the spaced apart in Fig. 1 and 2 juxtaposed two casting devices 10, a manipulator 21 may be arranged for handling the workpieces. Furthermore, a guide 28 may be provided, which is realized in the illustrated example by a rail system on which a transport carriage 6 for receiving or removal and delivery or transfer of the furnace 4 is arranged.

In this case, the transport carriage 6 oscillates between the casting devices 10 and a provisioning position remote from it, for example a station 8 for processing the melt.

FIG. 3 shows how the transport carriage stops in front of a casting device 10 in order to transfer a furnace 4 filled with melt from its furnace positioning point into the casting device 10, which has not yet been provided with an oven 4. Previously, the transport carriage 6 has received this oven 4 leaving a vacant location at the station 8. According to FIG. 1, the transport carriage 6 has a further oven positioning point 29. As a result, a time-saving change of an empty in the casting apparatus 10 arranged furnace 4 against a furnace 4 filled with melt possible. The transport carriage 6 first receives the furnace 4 filled with melt in a first Ofenpositionierstelle 20 from the station 8, then moves to the casting apparatus 10 to receive the empty oven 4 in the second, still free Ofenpositionierstelle 29, then transferred the verse with melt - Henen oven 4 from the first Ofenpositionierstelle 20 in the oven-less pouring device 10, to finally take the already recorded empty oven 4 to the station 8, so that it can be transferred to a vacancy of the station 8 for reloading with melt. The transport carriage 6 may have two floors arranged above one another, a lower floor being provided for the transport of the furnace 4 and an upper floor 8 for transporting at least one mold. To accommodate the molds, the transport carriage 6 can stop at a stage 9 and transfer the molds provided there from the stage 9 to the upper level. Subsequently, the loaded with the oven 4 and the mold transport carriage can go to one of the casting devices 10. The transfer of the molds on and from the transport carriage 6 can be done by means of tool carriage 7.

However, it is also conceivable that the at least one furnace 4 is driven on guides from the lower chamber of the casting device directly to a removal and receiving station, without the use of the transport carriage. It is also advantageous if the rails extend on several sides of the lower chamber.

The casting apparatus may have at least one heating device for heating the riser, for example in the form of a gas burner, a heating coil, a radiant oven, etc., which can be inserted into the lower chamber instead of the furnace 4. After removal of the furnace 4, the riser 23 may be replaced by the furnace instead of the furnace 4 heated in the lower chamber heater to prevent cooling of the riser 23.

For the sake of order, it should finally be pointed out that, for a better understanding of the structure of the device according to the invention, these or their components have been shown partly unevenly and / or enlarged and / or reduced in size. REFERENCE NUMBERS
