    The invention relates to a plant for casting, in particular according to the preamble of claim 1, and a method for casting.
    Such systems with a casting device, in particular for casting under a pressure generated by a gas phase found in the foundry technology, in particular for the production of castings with high physical and mechanical characteristics, in particular from light metal alloys, application.
    DE 1178979 A discloses a die-casting method in which, under the action of a pressure difference, a melt is conveyed from a furnace located in a hermetically sealed feed chamber through a pouring tube into the cavity of a casting mold, wherein the casting mold is arranged in another hermetically sealed compensating chamber , In the compensation chamber, the casting solidifies at the temperature present there and at the pressure present there. Subsequently, the finished casting is removed from the mold and a new casting cycle can be performed.
    The counter-pressure die casting method known to the person skilled in the art, also known as CPC (Counter Pressure Casting) casting method, is a further development of the so-called low-pressure casting method and of various publications, for example EP 0 221 196 B1, EP 0 564 774 B1 or US Pat DE 34 22 121 A1 is known. * * -2-lm contrast to, the expert also known low-pressure casting method, however, not only the casting furnace, but also the mold or mold is pressurized with compressed gas.
    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 rise of the melt in the mold.
    A disadvantage of the known systems that some operations that are not directly connected to the actual casting process, are very labor intensive. In addition, the changeover times, in particular for changing the casting mold or for resending a furnace with melt, relatively long.
    The invention is therefore based on the object, a system, in particular a counter-pressure Kokillengießanlage or in particular a low-pressure mold »* * * · ·« «-3- casting plant, and a method for producing castings by casting under pressure, in particular by counter-pressure die casting or in particular by low-pressure die casting, in which the degree of automation and the control quality of the plant and the process and thus the productivity can be increased. In addition, the changeover times are shortened and labor-intensive steps are facilitated in order to achieve an increase in productivity.
    The term " pouring under pressure " the casting under or overpressure, normal pressure or negative pressure understood, and depending on the application, one or more of these casting methods may be advantageous. These casting methods include, for example, the Kippgießverfahren, the Bodengießverfahren, Seitengießverfahren or the Kopfgießverfahren, wherein here, depending on the application, one or more of these casting methods may be advantageous.
    The above object is achieved in a system, in particular according to the preamble of claim 1 or 2, by the characterizing features of claim 1 or 2. Furthermore, the object is achieved by a method having the features of claim 24 or 25. - 4 -
    A pressure casting apparatus, in particular a counterpressure die casting machine or in particular a low pressure die casting machine, has at least one casting device comprising a lower hermetically sealable chamber and an upper, preferably hermetically sealable, chamber separated by an intermediate plate or platen. If the hermetic sealability of the upper chamber does not matter, the chamber can virtually also comprise only one frame, as may be the case, in particular, in the case of a low-pressure permanent mold casting machine. The lower chamber has or is formed by a furnace with melt. Arranged in the upper chamber is an approximately horizontally divided mold consisting of a lower mold half disposed on the intermediate platen and an upper mold half disposed below an upper vertically movable support structure, preferably another plate is, exists. The upper and / or the lower mold half can be formed from individual moldings. The furnace with melt and the mold are connected to each other via at least one, preferably mounted on the intermediate plate or the platen riser.
    According to the invention, it is provided that the upper mold half can be pivoted from the horizontal position into an approximately vertical position such that the inner surface of the mold half, preferably by a person, can be treated to make work easier and save time. -5-
    Instead of crawling between the lower mold half and the upper mold half to perform cleaning operations, application of sizing or corrections to the inner surface of the mold half, the person involved in this treatment can do this work with a tremendous amount of time by having the person perform this work before Casting device executes standing. This leads to a significant increase in productivity.
    The same applies if the lower mold half is pivotable from the horizontal position to an approximately vertical position, such that the inner surface of the mold half, preferably by a person, work easier and time-saving treatable.

    It may be particularly advantageous if the mold half is up to 135 °, preferably up to 90 °; particularly preferably by up to 85 °, is pivotable from the horizontal position.
    Preferably, the upper mold half can be pivoted downwards. Preferably, the lower mold half can be pivoted upwards. For the pressure supply of the lower chamber or the lower pressure chamber or furnace interior and optionally (for example in the case of a counter-pressure Kokillengießanlage) for the pressure supply of the upper chamber or the upper pressure chamber via corresponding pressure lines, it may be advantageous if two parallel connected Valves are provided, namely a large valve to the main filling of the pressure chamber with pressure medium and a small valve for precise pressure adjustment within the pressure chamber.
    Conveniently, a pilot control for controlling each valve can be provided, which can be realized as a map or as a mathematical model.
    To fill the pressure chambers, the small valve is advantageously opened first to about 40 to 60%, preferably to about 45 to 55%, particularly preferably to about 50%, then the large valve with the control value from the pilot control, corrected by the preset flow the small valve is pressurized, and finally, with the small valve, the pressure is precisely controlled.
    Through such a trained pressure supply, a higher productivity can be achieved and the control quality can be significantly improved.
    It may also be advantageous if two casting devices, in particular two Säulengießvorrichtungen or machines, are provided which are arranged at a distance next to each other, wherein between the casting devices, a manipulator for handling workpieces or tools of both casting devices is arranged. Suitable manipulators are known to the person skilled in the art. • «MM ·« «» • «MM ·« «»
