Mold plate

1. A mold plate, comprising:

a casting side;

a rear side remote from the casting side;

a cooling channel arranged in the rear side and open with respect to the rear side; and

an insert arranged in the cooling channel to reduce a flow cross-section of the cooling channel, said insert fastened to the mold plate in a pivotally movable manner so as to be able to pivot from a closed position into an open position.

2. The mold plate of claim 1 , wherein the insert pivots about a pivot axis which is perpendicular to a longitudinal direction of the cooling channel.

3. The mold plate of claim 1 , wherein the insert pivots about a pivot axis which is arranged at a lower end of the mold plate so that the insert is swingable downwards from the closed position into the open position.

4. The mold plate of claim 1 , further comprising a securing element arranged on the rear side and configured to hold the insert in the closed position.

5. The mold plate of claim 4 , further comprising a plurality of said insert placed in adjacent relationship, said securing element configured to simultaneously lock the plurality of said insert in the closed position.

6. The mold plate of claim 1 , wherein the insert has an inner side which, in the closed position, is in partial contact with a casting-side-remote cooling surface of the cooling channel such as to form a cooling gap between the cooling surface and the inner side.

7. The mold plate of claim 1 , wherein the insert has an inner side having grooves, and further comprising webs received in the grooves in one-to-one correspondence in the closed position of the insert, so that, between adjacent ones of the webs, a cooling gap is established between the insert and the mold plate.

8. The mold plate of claim 1 , wherein the insert is releasably connected to the mold plate.

9. The mold plate of claim 1 , further comprising a connecting element arranged between the insert and the mold plate.

10. The mold plate of claim 9 , wherein the connecting element is a pivot pin mounted in the mold plate.

11. The mold plate of claim 9 , wherein the connecting element is a hinge connected to the insert and the mold plate.

12. The mold plate of claim 1 , further comprising a projection arranged in the cooling channel and received in an opening of the insert, when the insert pivots into the closed position.

13. The mold plate of claim 1 , further comprising:

a plurality of said insert; and

fastening points arranged between adjacent ones of the plurality of said insert.

14. The mold plate of claim 1 , wherein the insert has an indentation on a longitudinal side of the insert.
