초록 ▼

Apparatus and method for forming hollow articles from plasticized materials are disclosed. A preform is partially formed under substantially no pressure on a preform core by introducing the core into a void-free charge of plasticized material that is placed in a preform cavity from a source of the plasticized material. After the preform core and preform cavity have moved together to define a preform mold space, the charge of plasticized material is subjected to a pressure forming step to form a completely packed preform on the core. The preform is then blow-molded in a blow cavity by introducing blowing gas into the preform through the preform core. Neck mold structure that strips and releases the formed article from the core is also disclosed.

Apparatus for use in blow molding hollow containers and like products from plasticized material comprising: a. a frame system comprising side-by-side first and second support members providing a pair of side-by-side stations; b. material delivery means, having a member connected with a source of said material, being provided at one station supported on the first support member to define said station as a material supply station; c. a preform mold having an axially extending mold cavity defined by a side wall fixed to a bottom; d. a preform cavity-closing closure mold, mounted by the second support member to remain at said second station, and defining said second station as a mold station; e. said closure mold having an axially extending preform core configured to be received within said cavity and to define a preform mold space between the core and cavity; f. carriage mechanism for shifting said preform mold transversely from the material supply station and a position of registry of the cavity with said material supply member to a position of axial alignment of the cavity with said core, and back to said material supply station; g. mechanism for relatively axially moving said closure mold and preform mold to a mold closed position to shape a charge of material delivered to said cavity at the material supply station to the preform mold space and form a preform; h. mechanism for relatively axially moving said closure mold and preform mold to effect an axial separation thereof in which the preform adheres to the core; i. a blow mold having transversely separable parts movable from a radially separated position to a closed molding position around said core and the preform thereon; j. means for supplying gaseous pressure to said closure mold to blow the preform from the core to the configuration of the blow mold; and k. mechanism for moving the blow mold parts transversely to closed molding position, when the preform mold and closure mold are in axially separated relation, and back to separated position so that the product formed can be removed.
