- a method for the production of products made of metal and a rotor produced by the method for an electric motor is known (DE 10 2013 208 151 A1).
- metal or copper alloy melt under pressure of a casting mold is supplied by means of a casting machine.
- the casting machine is for this purpose equipped with a relative to a horizontal obliquely, preferably vertically arranged piston.
- the piston is moved in the direction of a longitudinal axis of the casting mold so that the molten copper in the filling chamber is pressed into a cavity of the casting mold.
- voids porosity occurs because most of the cast metals have a slightly lower density in the liquid state than in the solid state. As a result, the metal takes less space when it solidifies.
- the shrinkage can be minimized as the liquid metal enters the mold while it solidifies.
- hot spots can occur in complicated cross sections.
- Voids porosity can be controlled by improved mold design, print intensity, and metal temperature.
- the invention has for its object the device by means of a compression device or multi-adjustable device in such a way that cavitation avoided and after the removal of the mold from the casting no after-treatment will be more necessary.
- the chamber for receiving the melt is associated with a closing device and a device for compressing the melt, wherein the compression of the melt occurs only when the chamber is closed.
- molding chamber the chamber for receiving the melt

- the filling pressure may be 1 bar or greater, with the compression pressure at about 50 bar and may be much higher, depending on how the melt is composed.
- the melt present in the sprue area can flow away by gravity, so that it does not solidify as before and adhere to the casting, since the closure device with its pointing into the front gate opening on the same transverse plane as the outer end of the bore of the rim for receiving the hub is located. Due to the advantageous embodiment of the closure device is obtained after removal of the blank from the mold chamber a fully formed hole in the rim, which then hardly treated or, as before, still has to be drilled.

- the adjusting device as a multi-stage Stellvor- direction has the adjustable hydraulic cylinder, on the piston, the adjusting part is connected to the pressure plate, which can be brought against the pressure part to the plant, which is designed as a multi-part guide column, the coaxially adjustable in in the upper part or molding provided openings is guided.
- the piston of the hydraulic cylinder of the adjustable device to extend through a concentrically arranged opening provided in the insert part or the guide column, to which the cooling core designed as a closing part is connected, which in the case of the embodiment is connected.
- the piston rod presses the closing part or the cooling core against the inlet opening or sprue opening.
- the insert part or pressure part or guide pillar has one or more guide rods which extend and are guided through openings provided in the upper mold part, surround the cooling core and are fixedly connected to a connection part or center insert which is connected to the cooling core is firmly connected.
- the melt is compressed in a further stage or an adjustment of the insert or the pressure member or the guide column with its lower part and / or connected thereto connection part or center insert in the mold chamber for receiving the melt.
- cooling core can also be closing part and with its lower pointing in the direction of the gate opening end on the same transverse plane as the end face of the bore of the rim when it is included in the mold chamber mer.
- Fig. 1 b shows the second stage of the internal closure of the casting tool, the cooling core being moved downwards in the direction Z by the three-stage telescopic cylinder, thereby closing the opening of the sprue bushing
- Fig. 1c shows the third stage of operation, wherein the pressure plate, the guide column and the middle insert are moved downwards in the direction Z with the aid of the 3-stage telescopic cylinder and thus the compression of the melt occurs;
- Fig. 3 the rim according to the inventive method without sprue and with molded bore for receiving a wheel hub.
- FIG. 1a with a casting tool for a device for producing cast parts or rims 18 in aluminum casting or wheel rims for motor vehicles in the low-pressure method or high-pressure method, wherein the filling pressure of the molding chamber for the device described below at approx. 2 bar or higher.
- the casting tool 1 according to FIG. 1 a is filled via a sprue bush 2 with melt at a low pressure of about 1 bar or 2 to 5 bar.
- Side parts 4 have for this purpose a position shown in FIG. 1 a to 1 c taken.
- the casting tool 1 consists of a plurality of movably arranged side parts 4 with a lower part or a lower molded part 3 received. At least the upper part 5 is connected to the plate 17 and thus also to a spacer column 1 1 and a cover plate 12 of the device.
- a demolding plate 10 is connected to an adjusting device 13. With the help of the demoulding plate 10, after the cooling process of the melt, the rim, as described in detail in the unpublished patent application 10 2016 104 019.3 on pages 7-1 1, repelled from the mold and then removed.
- the side parts 4 shown in FIGS. 1 a to 1 d consist of at least two, in particular four, side part segments, which are led away from each other via oblique slide or slide strips and thus release the casting tool 1 after the demolding process, as in the patent application 10 2016 104 019.3 is described in detail on pages 7-1 1.
- the rim 18 For demolding of the molding or the rim 18 acts at least one adjusting device, not shown in the drawing with the side parts 4 medium or directly together and is thereby moved away from the rim 18.
