Patent ID: 7958930

Claim:
A casting die wall ( 100 ) of a casting die for casting a molten metal, which comprises: a casting die front plate ( 110 ) with a hot side (H) that faces the molten metal, a cold side (K) that faces away from the molten metal, and at least one blind borehole ( 112 ) on the cold side (K); a casting die rear plate ( 120 ) with at least one transverse borehole ( 122 ), such that the casting die rear plate ( 120 ) is joined with the casting die front plate ( 110 ) on the cold side (K) of the casting die front plate ( 110 ) in such a way that the transverse borehole ( 122 ) is at least approximately aligned with the blind borehole ( 112 ); and a sealing element ( 140 ) with a longitudinal borehole, such that the sealing element ( 140 ) is arranged in such a way in the transition region ( 115 ) between the casting die front plate ( 110 ) and the casting die rear plate ( 120 ) that the longitudinal borehole is at least approximately aligned with the transverse borehole ( 122 ) and the blind borehole ( 112 ), wherein the tubular sealing element is designed with the shape of a dog bone with a bulge ( 142 a , 142 b ) in its two end regions, such that, in its installed state, the bulge ( 142 a ) at one end is inserted in the blind borehole ( 112 ) in the front plate ( 110 ) of the casting die, and the bulge ( 142 b ) at the other end is inserted in the transverse borehole ( 122 ) in the rear plate ( 120 ) of the casting die.
