To provide a casting machine for a metal product which can prevent a metal stock from being deposited due to local overheating of a stripping edge caused by friction with the metal stock when the external layer of the metal stock is being stripped by means of the stripping edge.
The casting machine for the metal product is equipped with a substrate 1 having a cavity 16, a pressure feeding mechanism 3 which feeds, under positive pressure, the cavity 16 with the metal stock M in a solid-liquid heterogeneous phase, and an annular blade 4 placed near the inlet of the cavity in the substrate. The blade 4 has the stripping edge 44 for stripping the external layer of the metal stock M when the metal stock M is pressure fed into the cavity 16 by means of the pressure feeding mechanism 3. There are formed cooling fins 45 on the outer circumference of the blade as a means for removing heat from the stripping edge 44. The heat removal means may be composed of a passage of coolant provided inside the blade 4 and a pumping mechanism provided outside the blade 4.
