Claim:
Broadside ( 100 ) of a funnel mold for the casting of metal, with: groove-shaped cooling channels ( 110 ) in the backside (R) of the mold plate ( 100 ); a plurality of recesses (A 1 , . . . , A 5 ) in the backside; and a plurality of block-shaped filler elements ( 140 - 1 , . . . , 140 - 5 ) for the at least partial sealing of the recess; wherein the recess (A 1 , . . . , A 5 ) is formed in such a manner, that each crosses a plurality of cooling channels ( 110 ) diagonally to their longitudinal direction; and that each recess is in its expansion in longitudinal direction of each cooling channel confined at least to a section of the cooling channel, and that, in this longitudinal direction, each recess has a rectangular-shaped and/or wedge-shaped cross-section, so that the cross-section of the cooling channels ( 110 ) in the broadside ( 100 ) in the area of the crossing recesses varies in a cascaded manner and is provided with the corresponding block-shaped filler elements ( 140 - 1 , . . . , 140 - 5 ), whereby the cooling channels permit free flow between steps of the cascaded cross-section, wherein in the backside of the broadside ( 100 ), and distributed over the height of the broadside, are provided several recesses (A 1 , . . . , A 5 ) of respectively varying depth, wherein the depths of the individual recesses increase with increasing distance from the upper rim ( 105 ) and from the mold center of the mold.
