Abstract
Quick change blow mold tooling includes a pair of mold cavity blocks that cooperate to define a series of blow cavities. The tooling further includes a pushup plate having a series of bottom contours that plug the otherwise open bottoms of the cavities when the pushup plate is against the bottom of the mold blocks. Each mold block is quickly attached to and detached from its supporting back plate using studs that fit into receiving holes on the back plate and cam locking shafts that are accessible from opposite side edges of the back plates. The back plates thus remain secured to platens of the bottle forming machine during change out of the tooling. Similarly, the push up plate has a pair of locking studs projecting from the underside thereof that are received within socket members attached to the machine. The socket members are provided with quick release threaded couplers that can be locked and unlocked by hand.
