An embodiment of the invention is a disappearing mold for double-layer casting of a loader rod head, comprising a vertical bar, the side wall of the vertical bar being glued with a connecting rod close to both ends, and two connecting rods being glued with a cross bar at one end. The two side walls of the two cross bars are provided with an equal distance distribution. The connecting columns are connected with the rod head mold. The two rod head molds on the same vertical line are connected with the same supporting column at a close side. The top of the rod head mold on the vertical bar is connected with the top frame. The invention can produce multiple rod heads at a time, greatly improve the casting efficiency of the rod head, and reduce the cost.
