ABSTRACT:
In a forcibly cooled casting apparatus including a lower surface plate and an upper cooling plate covering the lower surface plate with a casting mold therebetween, a plurality of tube members extend through the casting mold and having a lower end supported on a receiving base of the surface plate and an upper end received in a positioning hole of the cooling plate. A sleeve provided on the cooling plate supports a protection case within which extends a cooling nozzle which passes through the cooling plate. The cooling nozzle is connected to a source of cooling fluid and has a tapered tip which fits in the upper end of the tube member so that cooling fluid can flow through the tube member. A spring compressed within the protection case biases the cooling nozzle into fluid tight contact with the tube member. A detector is provided for detecting improper positioning of the cooling nozzle.
