ABSTRACT:
The pattern plate of a matchplate molding machine is attached to a drag flask by spring-loaded clamps which may be rapidly opened to enable the plate to be quickly and easily removed from the flask and replaced by another plate. Locating members are attached to the flask in laterally opposed relation with the clamps and coact with the clamps to fixture the pattern plate accurately on the flask. A removable operating handle is provided for opening the clamps and carries a latch for releasably holding the clamps in their open positions during changing of the pattern plates. A conventional bolt-on pattern plate may be converted for use with the clamping system by attaching bars with downwardly inclined upper surfaces to the pattern plate, the bars being secured within notches in the side edges of the plate.
