Intelligent chill control device for counter gravity casting of copper alloy propeller for large ship

The invention discloses an intelligent chill control device for counter gravity casting of a copper alloy propeller for a large ship, and relates to a chill device for counter gravity casting. The intelligent chill control device solves the technical problem that the solidification process of a casting piece cannot be precisely controlled through existing counter gravity casting. The intelligent chill control device is composed of a computer, a gas circuit solenoid valve, a compressed air storage tank, a chill and a temperature sensor. The computer is connected with the gas circuit solenoid valve and the temperature sensor. The temperature sensor is arranged on the lower surface of the chill. The compressed air storage tank communicates with the chill. The gas circuit solenoid valve is arranged on a chill gas inlet pipe. A gas exhaust hole of the chill is provided with a chill gas outlet pipe. The intelligent chill control device for counter gravity casting of the copper alloy propeller for the large ship is
