ABSTRACT:
Blow molding apparatus for manufacturing containers, the apparatus having a blow station, a parison forming station to one side of the blow molding station, a container trim station at the other side of the blow molding station and a multiple station mold carrying slide for shuttle movement between a first position below the parison forming and blow molding stations and a second position below the blow molding and trim stations. The shuttling movement of the slide takes place between a pair of movable platens that are capable of opening and closing the molds. Improved structure in the apparatus insures that the blow heads will not separate from the molds during blowing, provides for trimming of the containers at the trim stations and for deposit of trimmed containers in upright positions on a conveyor.
