Abstract

The invention relates to a device and a method for producing components comprising a mould building device ( 1 ) for producing lost casting moulds, and a casting device ( 2 ) connected to the mould building device for casting components in the lost casting moulds, characterised in that the mould building device is suitable for the continuous layering of moulding plates ( 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23 ), wherein a respective at least three of said moulding plates form a casting mould.

First claim

The invention claimed is:

1. A device for producing components comprising a mold building device for producing lost casting molds, and a casting device connected to the mold building device for casting the components in the lost casting molds,
wherein the mold building device is configured for the continuous layering of molding plates, wherein a respective at least three of said molding plates form a lost casting mold of the lost casting molds,
wherein the mold building device is configured to at least temporarily change a stacking direction in such a way that a vertical stack of molding plates is adjacent to a horizontal stack of molding plates.

2. The device according to claim 1 , wherein the mold building device is suitable for producing the molding plates individually, which each delimit a cavity of the lost casting mold on at least one of their sides.

3. The device according to claim 1 , wherein the mold building device has an infeed device for moving individual molding plates of the molding plates to form a stack of molding plates, and at least one of (1) an alignment element on which the molding plates can be aligned, and (2) that the mold building device has at least one tool for shaping positive-locking elements on the molding plates, wherein the positive-locking elements each enable the alignment of a molding plate on a molding plate directly adjacent thereto.

4. The device according to claim 1 , wherein a demolding device is downstream of the casting device.

5. The device according to claim 1 , wherein the mold building device is suitable for producing the molding plates individually, which each delimit a cavity of a lost casting mold of the lost casting molds on at least two of their sides.

6. A method for producing castings, in which first molding plates are produced and automatically continuously layered in a mold building device, a respective casting mold being formed by at least three molding plates delimiting a common cavity, wherein a stacking direction is at least temporarily changed and a vertical layer stack of molding plates is rotated by 90 degrees after it has been layered and is joined together with further mold elements, and a casting material then being poured into the casting molds within a casting device connected to the mold building device.

7. The method according to claim 6 , wherein the mold building device is arranged in a fixed manner and that the individual molding plates are at least one of (1) placed on a drivable conveying element and (2) that the molding plates layered to form casting molds are moved relative to the casting device by means of a drivable conveying element.

8. The method according to claim 7 , wherein the drivable conveying element comprises a conveyor belt.

9. The method according to claim 6 , wherein at least one of (1) an infeed device of the mold building device moves along a stack of molding plates and (2) that a crucible of the casting device moves along the stack of molding plates in order to activate individual casting molds.

10. The method according to claim 6 , wherein at least one of (1) the individual molding plates of the molding plates are each used for a plurality of adjacent casting molds and (2) that casting cores are also integrated into the molding plates.

11. The method according to claim 6 , wherein after the layering, mold covers, each having at least one of a funnel and a feeder, are placed on one or more molding plates such that the at least one of the funnel and the feeder is connected to at least the common cavity of the respective casting mold.
