A casting die l for producing two die-cast products simultaneously, a runner 4 which is provided from a flow divide member 10 to a cavity 6, the runner is comprised of the first runner 12, 22, the second runner 13, 23 and the third runner 14, 24, the first runner is parallel in a division surface 11 of the die, the second runner 13, 23 is generally perpendicular to the first runner and the third runner connects the second runner to the cavity. And the R shape (radius of curvature r1) of the joint 15, 25 of the first runner and the second runner is larger than the R shape (radius of curvature r2) of the joint 16, 26 of the second runner and the third runner.
