  • Patent number: 6789301
    Abstract: An apparatus and method for allowing the spotting of one or more movable cores to mating portions of a mold. The present invention provides for the placement of a mold on a support structure and the releasable connection of each movable core to a force exerting device. The force exerting device allows for controlled and repeatable movement of the movable core or cores to which the force exerting device is attached. The present invention preferably also allows each movable core being spotted to be set to, and retracted from the mold, to a position where adjustments may be made to the movable core and/or the mating portion of the mold without removing the movable core therefrom. The present invention, therefore, provides for a higher quality and more efficient spotting of movable mold cores than is currently possible.
