ABSTRACT:
A quick change system and method of interchanging molds on plastic extrusion blow molding machines is disclosed wherein a universal standard subplate is provided for use with different blow molding machines on which a variety of different mold units are removably mounted on the standard subplate with the subplate establishing a preselected precisely aligned relation automatically between the mold unit and a machine platen. A quick release locking device is provided between each mold unit and a unitary standard water manifold and detabber assembly. The unitary standard assembly is provided as a one-piece component with fluid connections communicating respectively with water and air supply sources of the water manifold and detabber and which are conveniently maintained attached without being disconnected during detachment of the unitary standard assembly from the mold unit during a mold change.
