The present invention relates to a device to inject molten metal for casting rolls capable of shortening a transfer time of heavy weights, improving an injecting speed, and securing operation stability by integrally forming an injection unit on the upper part of a heavy weight unit. Provided is the device including the heavy weight unit pressurizing an upper mold flask when the molten metal is injected and the injection unit formed to be integrated on the upper part of the heavy weight unit and injecting the molten metal through a penetration hole of the heavy weight unit. |
