A machine for making molds in which cast welding rods can be formed includes a vertically movable pressure plate having a plurality of pointed depending rods thereon and apparatus including a hydraulically actuated piston and cylinder assembly for moving the pointed rods into and out of a sand filled flask to form cavities in which welding rods are subsequently cast. The machine includes a second pressure plate which is apertured and through which the rods move with the second pressure plate forming pouring buttons and runner configurations in the sand in the flask to facilitate pouring of the metal in the cavities formed by the rods.
