For a die casting machine 10, an alignment tool having a tubular connecting sleeve 19 inserted in the shot sleeve 18 of the die casting machine 10 and concentrically aligned with the shot sleeve 18 by tapered cones 20 and 22 engaging the ends of the shot sleeve 18. A rotatable shaft 25 is disposed within the connecting sleeve 19 and carries one or more brackets 28 on its outer ends. Mounted on the bracket 28 is a dial indicator 33 having a work piece engaging spindle point 33a to bear on alternative surfaces of the die casting machine such as the die 17 or outside diameter of the shot sleeve 18 to detect and visually indicate any misalignment of the shot sleeve 18, die 17 and front platen 16 when the rotatable shaft 25 is rotated within the connecting sleeve 19. An auxiliary bracket 34 mounted on the bracket 28 carries an extension rod 35 having spaced apart dial indicators 38 and 39 with spindle points 38a and 39a bearing on the shot cylinder rod 15 to detect bends therein, a worn cylinder rod bearing, and axial and angular misalignment of the shot cylinder 13 and shot sleeve 18.
