## Abstract

The invention relates to a device for producing cast parts, in a pressure method using a casting tool (20) which includes movably arranged lateral parts (4) with a base (1) that receives a lower part or a lower mold part (3) and a plate that has an upper part (7) or an upper mold part (5). At least the upper part (7) together with a removal plate (10) and the upper mold part (5) can be moved in the vertical direction (Z) relative to the standing surface of the casting tool (20) using at least one adjusting device (17), and the lateral parts (4) can likewise be moved in the horizontal direction (X) using the adjusting device and/or additional adjusting devices.

wherein, at least one of the at least one adjusting device (17) is configured to interact directly or indirectly with the demoulding plate (10) to demould the cast part (9), and during the vertical adjustment, the upper mold part (5) is adjustable in the vertical direction (Z), and then the side parts (4) are adjustable in the horizontal direction (X) at least via the at least one adjusting device (17),
the at least one adjusting device (17) is configured to interact with positive control elements, which cause a continuous or uniform movement of the side parts (4) in an inclined direction relative to the supporting surface of the casting tool,
the positive control elements are constructed as sliding surfaces (19a, 19b, 50a, 50b, 60a, 60b, 70a, 70b),
the casting tool (20) is configured with a plurality of sliding surface pairs, characterized by that
a first sliding surface pair (60a, 60b) extending horizontally is consisted of a horizontal first sliding surface (60a) arranged on the demoulding plate (10) and a second sliding surface (60b) horizontally arranged on a first sliding element (8);
a second sliding surface pair (50a, 50b) extending in an inclined direction is consisted of a third sliding surface (50a) arranged on the first sliding element (8) and a fourth sliding surface (50b) arranged on the demoulding plate (10);
a third sliding surface pair (19a, 19b) extending in an inclined direction is consisted of a fifth sliding surface (19a) arranged on the first sliding element (8) and a sixth sliding surface (19b) arranged on a second sliding element (11);
wherein, a fourth sliding surface pair (70a, 70b) extending horizontally is consisted of a seventh sliding surface (70a) arranged on the first sliding element (8) and an eighth sliding surface (70b) arranged on the upper part (7).

### Claim 2 (depends on 1)

The device according to claim 1, wherein, the casting tool (20) is further configured with a fifth sliding surface pair (18a, 18b) extending at an angle of 45° is consisted of a ninth sliding surface (18a) arranged on the first sliding element (8) and a tenth sliding surface (18b) arranged on the upper part (7).

### Claim 3 (depends on 2)

The device according to claim 2, wherein, the plate or the upper part (7) and the second sliding element (11) are firmly connected to each other and connected to the casting tool (20), wherein when the demoulding plate (10) is directly or indirectly pressed against the first sliding element (8), with the interaction between the fifth and the sixth sliding surfaces (19a, 19b) of the second sliding element (11) and the first sliding element (8), between the third and the fourth sliding surfaces (50a, 50b), and between the ninth and the tenth sliding surfaces (18a, 18b) as well as between other horizontally-extending sliding surfaces (70a, 70b), the first sliding element (8) is moved outward, such that the third and the fourth sliding surfaces (50a, 50b) of the first sliding element (8) and the demoulding plate (10) abut against each other, and when the adjusting device (17) further moves downward in the vertical direction (Z), the side parts (4) are forced and guided to move downward and outward on an inclined plane (X, Z).

### Claim 4 (depends on 2)

The device according to claim 2, wherein, the first sliding element (8) is constructed as a T-shaped rod which comprises a horizontal part (22) and a vertically-arranged connecting piece (21) in which an opening (53) is arranged to receive a fixing element, wherein the fixing element is connected to one of the side parts (4) by means of the opening.

### Claim 5 (depends on 4)

The device according to claim 4, wherein,
the second sliding element (11) and the upper part (7) are firmly connected to each other via a fixing element and are connected to the casting tool (20) in a vertically adjustable manner, wherein the connecting piece (21) arranged on the first sliding element (8) is received in an elongated opening (51) arranged on the upper part (7), to allow for lateral adjustment of the side parts (4).

### Claim 6 (depends on 4)
