Abstract
A mold flask assembly is provided with a novel clamping mechanism for clamping a pattern plate in the mold flask assembly of an automated molding machine. The clamping mechanism comprises a first clamp abutment and a clamping head extending along an axis. The clamping head provides a second clamp abutment. The first and second clamp abutments engage each other in a clamped position. The first and second clamp abutments are spaced along the axis and angularly displaced in a released position. A combination rotary and linear actuator is operative to facilitate relative linear translation and rotation between the rod and the bushing to move between the clamped and released positions.
Claims20
An apparatus, comprising:
- a cope flask;
- a drag flask;
- a pattern plate positionable between said cope flask and drag flask and having a pattern thereon adapted to create a cavity in a mold;
- at least one actuatable clamping mechanism for clamping the pattern plate to at least one of the cope flask and the drag flask, said clamping mechanism including an actuator having a linearly moveable shaft and a clamp fixed to the shaft;
- said actuator being mounted on one of the drag and cope flasks,
- said actuator being selectively actuatable for moving said rod and clamp between a clamping position with said clamp in engaging relation with one of the other of said drag and cope flasks or said pattern plate for clamping and retaining said pattern plate and a released position in which said clamp is in disengaged relation to said one of said other drag and cope flasks or said pattern plate.
