Definitions
- 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 Kokilleng understand compiler using a riser, through which the melt is conveyed up into the mold.
- 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.
- the platen by which the lower chamber is separated from the upper chamber, fixed in place and can not be changed in position.
- the oven is raised after being positioned in the lower chamber.
- 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.
- the oven 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 may be evacuated or filled with a protective gas.
- the solution according to the invention saves the second drive for lifting the furnace, whereby the overall height can 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 to the lower platen has the advantage that the riser is lifted by lifting the lower platen, whereby the riser very quickly removed from the range of the furnace and the furnace can be replaced very quickly.
- the upper chamber has an upper platen for an upper part of the at least one mold.
- the upper platen may have holding elements and optionally media interfaces for the upper part of the mold.
- the upper platen is slidably mounted in the vertical direction and 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 connecting element of the second connecting elements by a vertical displacement of the upper platen in the direction of the lower Platen is brought into engagement.
- This variant of the invention has the advantage that the upper platen and the lower platen can be moved together. So can be mitaufhoben or lowered by a lifting or lowering the upper platen, the lower platen. This is advantageous, inter alia, with regard to reducing the drive elements required for the movement of the mold mounting plates. In addition, can be synchronized in this way, the movements of the two platens with little effort, which is especially in a quick exchange of furnace and / or the mold disposed above advantage.
- each of the first connecting elements with the respectively associated second connecting element forms a positive and / or non-positive closure. 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 feed of the upper chamber with a mold advantage because it can be increased by lifting the upper platen of the available space for loading the upper chamber.
- 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.
- the upper platen can be connected to the upper part of the closed mold.
- the 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.
- 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.
- 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.
- 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, the cover structure having 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 above object can also be achieved with a system of the type mentioned in the present invention by having at least one casting device according to one of claims 1 to 8.
- 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.
- the manipulator can carry out further process steps, such as inserting cores, applying sizing, cleaning the mold and / or checking processes, for example by means of a camera.
