A wheel hub molding and casting die includes: a casting die shell, a supporting bottom plate, a limiting bottom plate, a lifting module, a module supporting plate, a lower die, an upper die and removable plates. The supporting bottom plate is mounted on the lower surface of the casting die shell. The limiting bottom plate is arranged below the supporting bottom plate. The module supporting plate is movably arranged in a molding cavity. The lifting module is connected between the bottom of the molding cavity and the module supporting plate. The lower die and the upper die are closed to form a pouring cavity. Annular slots are formed in the outer side wall of the upper die. Removable plate slots are formed in the upper surface of the casting die shell.
