An article repositioning apparatus for an injection stretch blow molding machine is disclosed for simultaneously molding a plurality of containers from plastic parisons. Between work stations, the apparatus repositions articles from a compact, evenly spaced first position to an extended, unevenly paired second position. After insertion of the articles into receivers slidably mounted on tracks, the receivers are moved by a servo motor to various separations by sliding movement along the tracks, the receivers attached to aligning ribs threadably engaged with ball screws. Simultaneously, the tracks are moved by a second servo motor to uneven paired separations by attachment to movable scissors having large and small scissor portions.

A blow mold assembly has a first and second carriage, and air cylinders for moving the first and second carriages along guide rods between an open position and a closed position. A first and second mold half are coupled respectively to the first and second carriages to define in the closed position at least one blow mold cavity. A lock situated on confronting surfaces of the first and second carriages locks the carriages together when the carriages are located in the closed position. The lock includes a pair of channel defining members coupled to one of the carriages having opposed edges including a series of teeth separated by interdental spaces, and a corresponding pair of cooperating toothed members coupled to another of the carriages and arranged to penetrate the interdental spaces. Each first mold half is movably mounted to the first carriage and is biased away from the second mold half. A chamber is situated between the first carriage and the first mold half having an opening for introducing fluid into said chamber in sufficient amount and under sufficient pressure to overcome the biasing forces and to resist any pressure applied to the first blow mold half during blow molding of an article within the blow mold cavity insuring faithful continuous mating of the two mold halves defining each blow mold cavity.

A blow molding machine configured to receive plastic parisons and output blow mold formed containers has a support frame having a trackway. A parison conveyor is attached to the support frame, and a blow mold assembly is positionable in its operating position within the support frame to receive parisons from the parison conveyor. A track mounted frame is movably supported by the trackway, with the track mounted frame configured to support the blow mold assembly as the blow mold assembly is moved outward from its operating position within the support frame to its service position adjacent to the support frame, with outward movement of the blow mold assembly permitting improved access for servicing.
