ABSTRACT:
A molding system includes apparatus for moving a flask from one portion of a mold car conveyor and for transferring it across the mold car conveyor loop and for depositing the mold at another portion of the mold car conveyor. The apparatus comprises a first structure for picking up the flask from the one portion of the mold car conveyor, a flask and mold feeder movable transverse of the mold car conveyor, and a second structure for picking up a mold from the flask and mold feeder at a mold removal station, and for moving the mold to the other portion of the mold car conveyor. A single fluid cylinder is provided for effecting the movement of the flask and mold feeder, as well as the first and second structures. A linkage means interconnects the single fluid motor with the first and second structures and the flask and mold feeder to effect these various movements.
In addition, the flask and mold feeder comprises a frame and roll-over mechanism is supported in the frame for effecting rolling over of the mold during movement of the flask and mold feeder. This roll-over movement is effected by a linkage which operates in response to reciprocating movement of the frame to effect the roll-over action. Further, the system includes a punch-out mechanism where the sand cake is maintained in a substantially horizontal plane and the cope and drag flasks are moved vertically to strip the sand cake from the flasks. After that vertical movement a suitable pusher member and brush move across the mold car on which the flasks have been supported to move the sand cake therefrom.
