This relates to a blow molding apparatus wherein plural preforms are directed to plural cavity blow molds by way of a pallet which supports the preforms by neck portions thereof. The pallets are positioned relative to blow molds of a set by way of a track. The track is transversely shiftable to present preforms transversely of the blow mold halves prior to the closing of the blow molds and there is associated with supports for the track wedge members which automatically lower the track relative to the blow molds more closely to position a supporting flange of each preform with respect to the upper surface of the blow molds. The track is finally further moved downwardly to engage the support flanges of the preforms with the top surfaces of the blow molds under controlled pressure conditions by means of fluid cylinders. This abstract forms no part of the specification of this application and is not to be construed as limiting the claims of the application.
In a blow molding machine wherein a plurality of preforms are simultaneously presented to a like number of split blow molds, and wherein the preforms are carried by a pallet movable along a track supported by rollers, said pallet forming means for retaining and carrying preforms to, while in, and from said blow molds without separation of the preforms from said pallet in terms of carrying function, said pallet forming means for supporting preforms when carried to and from said blow molds, and an apparatus for automatically transferring the support of the preforms from said pallet to said blow molds while the preforms are still carried by said pallet.
In a blow molding machine wherein a plurality of preforms are simultaneously presented to a like number of split blow molds, and wherein the preforms are carried by a pallet movable along a track supported by rollers, an apparatus for automatically transferring the support of the preforms from said pallet to said blow molds, said track being mounted above said blow molds a distance to initially position supporting flanges of preforms slightly above said blow molds, and said apparatus comprising means mounting said track for movement toward said blow molds to seat the supporting flanges of preforms carried by said pallet on said blow molds with such preforms being supported on said blow molds generally independently of said pallet.
