The casting chamber for a die casting machine includes a casting chamber jacket in which, over its entire length, there is provided an inner jacket defining the sliding surface for the pressure piston. In order for excessive heat in the inner jacket to be uniformly distributed and passed to the casting chamber jacket, copper rings are inserted in the inner jacket (3), the latter being pressed against the casting chamber jacket by means of screws threaded into a conical wedge. In this manner, heat distortion of the casting chamber can, for the first time, be held within limits, without requiring an oil or water cooling apparatus.
