Mould plate

1. A mould plate, comprising:

a casting side;

a rear side facing away from the casting side and having a cooling channel configured to open towards the rear side and having a cooling face opposite the casting side;

an insert arranged in the cooling channel such as to form a cooling gap between an inner face of the insert and the cooling face; and

a fastening bolt connecting the insert to a fastening point in the cooling face,

wherein the cooling gap extends, viewed from the fastening point towards the casting side, to an area below the fastening point.

2. The mould plate of claim 1 , wherein the fastening point is configured as an island elevation relative to the cooling face.

3. The mould plate of claim 2 , wherein a thickness of the mould plate between the casting side and the cooling face in a region of the fastening point is no smaller than in other regions of the cooling channel.

4. The mould plate of claim 1 , wherein the cooling face includes a plurality of said fastening point which are arranged offset to one another in a longitudinal direction and in a transverse direction of the cooling channel.

5. The mould plate of claim 1 , wherein the insert includes a rear support protrusion in a length portion of the fastening point with respect to a longitudinal direction of the cooling channel.

6. The mould plate of claim 1 , wherein the insert includes mutually directly opposite support protrusions on two long skies of the insert.

7. The mould plate of claim 6 , wherein the insert has between the mutually opposite support protrusions on the long sides a thickness which is greater than a thickness next to the support protrusions in a longitudinal direction.

8. The mould plate of claim 1 , wherein a working gap is arranged between the mould plate and the insert in a region of the fastening point so as to mount the mould plate floatingly relative to the insert at the fastening point, with the fastening point being displaceable relative to the insert laterally in a longitudinal direction and a transverse direction of the cooling channel without seizing.

9. The mould plate of claim 8 , wherein the working gap is less than 2/10 mm.

10. The mould plate of claim 1 , further comprising a screw-locking element configured to screw the insert to the fastening point.

11. The mould plate of claim 1 , wherein the fastening point has a threaded insert.

12. The mould plate of claim 1 , wherein the fastening bolt includes a bolt head which is arranged fully countersunk into a stepped through-bore in the insert.

13. The mould plate of claim 1 , wherein the insert extends over a web delimiting the cooling channel and/or grips in a rear pocket in a wall of a cooling channel.
