ABSTRACT:
A die mold is disclosed for the manufacture of crate like containers having lateral walls at least the upper portion of which are double-walled to provide substantial stability to the container and strength to the container walls. The die mold includes a base plate, lateral wedges which move upwardly and downwardly at an angle to the vertical during opening and closing of the mold, and slider means which are positioned on the lateral wedges and are movable with respect to the lateral wedges in a reciprocal direction relative to the walls of the containers formed by the die mold. Holding means is provided for holding the slider means in the same position relative to the container during mold opening, and control means are provided to permit the slider means to move back from the container walls after the container has been moved a predetermined distance away from the base plate.
