ABSTRACT OF THE DISCLOSURE A nozzle for a die casting machine of the type having mold halves that move toward and away from the parting line and engage a nozzle located on the parting line. The nozzle is free to "float" a limited amount on its surface mounting so as to assume a correct location at every shot in response to the die inserts closing around it. The nozzle also has a frusto-conical surface on the exit end of its aperture to provide a clean breakaway after a shot is made and only a small contact area is provided on the nozzle for engagement by the molds to reduce heat transfer thereto from the nozzle, moreover the structure increases specific superficial pressure between the nozzle area and the mold insert area in order to crush any metal debris that accumulates during the casting operation.
