Abstract (en)

The present invention relates to a gravity casting method by a robot, wherein a molten metal is cast by the robot into the chill while the latter carries out a pivoting on its axis by a hydraulic actuator, wherein the robot follows a previously set trajectory and detects the chill position by an encoder associated to the hydraulic pivoting axis, compares it to the casting cup position and, on the basis of the difference between said two values of position, acts on the flow rate of the fluid fed to the hydraulic actuator for accelerating or slowing down the rotation of said hydraulic axis. The invention also relates to a hydraulic axis for the rotation of the chill in the chilling process served by the robot, characterised in that it is controlled by a proportional valve controlled by the robot for adjusting the speed of rotation of the chill. <IMAGE>
