The mold is provided in the form of a casting mold for metallic workpieces. A mold blank is produced by severing it from a cast strand. After the severing process, an anode negative provided for shaping the workpiece is produced inside the mold blank. The casting mold is formed from a continuously cast material during the manufacturing process. Method of producing a casting mould (4) for copper anodes, characterised in that a mould blank (7) is produced by cutting it from a continuously cast strand (6) and then a casting mould (4) is produced from the mould blank (7) conforming to the shape of a copper anode for electrolytically producing copper. Method as claimed in claim 1, characterised in that the mould blank (7) is produced from a continuously cast strand (6) of copper. Method as claimed in claim 1, characterised in that the mould blank (7) is produced from a continuously cast strand (6) of a copper alloy. Method as claimed in one of claims 1 to 3, characterised in that the mould blank (7) is produced from a strand (6) with corners. Method as claimed in one of claims 1 to 3, characterised in that the mould blank (7) is produced from a round strand (6). Method as claimed in one of claims 1 to 5, characterised in that the cast strand (6) is produced with a cross-sectional surface that is smaller than an external contour of the casting mould (4). Method as claimed in one of claims 1 to 5, characterised in that the cast strand (6) is produced with a cross-sectional surface that is the same as an external contour of the casting mould (4). Method as claimed in one of claims 1 to 5, characterised in that the cast strand (6) is produced with a cross-sectional surface that is bigger than an external contour of the casting mould (4). Method as claimed in one of claims 1 to 8, characterised in that the mould blank (7) is processed by means of a rolling operation before producing the casting basin (5). Method as claimed in one of claims 1 to 8, characterised in that the mould blank (7) is processed by means of a forging operation before producing the casting basin (5). Method as claimed in one of claims 1 to 8, characterised in that the mould blank (7) is processed by means of a pressing operation before producing the casting basin (5). Method as claimed in one of claims 1 to 11, characterised in that the casting basin (5) is produced by removing material. Method as claimed in claim 12, characterised in that the casting basin (5) is produced by a milling operation. Method as claimed in one of claims 1 to 13, characterised in that the casting basin (5) is produced by a processing operation imparting shape. Method as claimed in claim 14, characterised in that the casting basin (5) is produced by a forging operation. Method as claimed in claim 14, characterised in that the casting basin (5) is produced by a pressing operation. Device for casting copper anodes, provided in the form of a casting mould (4) conforming to the shape of a copper anode for electrolytically producing copper, which has at least one casting basin (5) for moulding the copper anode, characterised in that the casting mould (4) is made from a strand of cast material. Device as claimed in claim 17, characterised in that the casting mould (4) is provided in the form of an anode negative (5) for producing the copper anode. Device as claimed in claim 17 or 18, characterised in that the casting mould (4) is made from copper. Device as claimed in one of claims 17 to 19, characterised in that the casting mould (4) is made from SE copper. Device as claimed in one of claims 17 to 19, characterised in that the casting mould (4) is made from SF copper. Device as claimed in one of claims 17 to 19, characterised in that the casting mould (4) is made from OF copper. Device as claimed in one of claims 17 to 22, characterised in that the casting mould (4) is made from a copper alloy. Device as claimed in claim 23, characterised in that the alloy is made from copper, to which up to 10% of alloying substances are added.
