Abstract: A mold for blow molding has a base component for forming at least one portion of a concave base of a container and comprising a mounting plate having connections for supply and return of a heat transfer fluid, a body having a molding surface thereon and having a substantially cylindrical recess having a roof spaced from the molding surface, a substantially cylindrical insert comprising a diverting surface, an inlet passage therethrough and open to the diverting surface and an outlet passage therethrough, the diverting surface spaced from the roof and side of the recess so as to define a cavity and a drain therefrom open to the outlet passage. In a method of blow molding turbulent flow is induced in heat transfer fluid conducted through the base component from impact with the roof and the turbulent flow is dispersed within the cavity over the diverting surface whereby heat transfer from the molding surface is enhanced.

Abstract: A mold assembly for blow molding comprises first, second and third mating mold components, molding surfaces of each of the first and second mold components being open to a mating face of the mold component and defining a portion of the exterior of an article to be molded, molding surfaces of the third mold component defining a portion of a closed end of the article to be molded, the mold assembly accepting at least one height insert selected according to a desired longitudinal extension of the molded article, and indexable adjusting means for altering the position of the molding surfaces of the third mold component to accommodate the effective longitudinal extension of the article to be molded. A blow molding machine comprises a press mechanism for operating a mold assembly and a mold assembly according to the invention, each mold component being mounted to a movable member of the press.

Abstract: A mold assembly for blow molding comprises first and second mating mold components, each mating mold component comprising molding surfaces open to a mating face of the mold component and defining the exterior of an article to be molded from a tubular parison and at least one replaceable element being attached thereto by retaining means accessible from the mating face thereof whereby the replaceable elements may be installed and removed while the mating mold component is mounted in a press of a blow molding machine. The replaceable elements comprise any of inserts comprising molding surfaces defining a neck portion of an article to be molded, a blow needle to pierce the wall of and pressurize the parison and heat pipes for transferring heat from the molding surfaces. A blow molding machine comprises a press mechanism for operating a mold assembly and a mold assembly according to the invention mounted thereto.

Abstract: A mold assembly for blow molding comprises first and second mating mold components, each mating mold component comprising molding surfaces open to a mating face of the mold component and defining the exterior of an article to be molded from a tubular parison and at least one height insert, the height and number of height inserts selected according to a desired longitudinal extension of the article to be molded, each height insert being retained in the mating mold component by retaining means retained with the mold component during insertion and removal of the height insert. A blow molding machine comprises a press mechanism for operating a mold assembly and a mold assembly according to the invention mounted thereto.

Abstract: A sealed bottle, a sealing method and an apparatus for blow molded aseptic bottles are disclosed. A sealing tool, having two integral blades, laterally displaces one side against the opposing side of an inflated parison. The sealing tools forms a seal which includes of a pair of indentations in collapsed portion of the parison, and a build-up material forming a dam therebetween.

Abstract: An apparatus and method for blow molding an article having a concave base wherein a mold has a base component comprising a molding surface for forming at least a portion of the concave base and a path for conduction of heat transfer fluid through channels within the base component. Improved heat transfer is effected in the base component by locating the channels at a plurality of distinct depths therein.

Abstract: The present invention provides a molding machine and a mold assembly having a quick change volume control insert. The volume control insert can be changed without disassembly of the mold or use of special tools. The molding machine includes a mold, a mold insert, a locking member, and a release member. The mold insert is received in one of the mold halves and further includes a mold detail defining a portion of the mold cavity, and a retention member. A locking member engages the retention member when the mold detail is received within the mold half. The release member, accessible from the exterior of the mold half, and is adapted to disengage the locking member from the retention member, allowing the mold detail to be removed.

Abstract: A plastic injection molding station having a mold assembly with a plurality of first mold sections and a plurality of second mold sections. Each of the first mold portions adapted to cooperate with one of the second mold portions so as to define a plurality of mold cavities, the mold cavities being of equal distance across the length of the mold assembly and further defining a shape of an article to be injection molded therein. The first mold portions and second mold portions are adapted for relative movement between an engaged position where the first and second mold portions define the mold cavities and a disengaged position where the first and second mold portions are separated from one another. The station also includes a locking assembly adapted to lock the first and second mold portions together in the engaged position.

Abstract: An apparatus for deflashing plastic blow molded articles is disclosed. The apparatus includes feed screw which engage one side of the container to move the container. A nesting wheel and a trim wheel are rotated in opposite directions to bring trim tools and nest tools together. The screw moves the container so that the nest tool engages the container and carries the container so that it is between the nest tool and trim tool as they intermesh. As a result, the container is nested, trimmed and released in one continuous motion.

Abstract: An apparatus for trimming the neck of a blow molded plastic bottle in which a reverse punch is mounted on an end of a shaft. A knife is also mounted to the shaft adjacent to the reverse punch and includes a cutting edge recessed from the cutting edge of the reverse punch. A stripper arm is mounted on the shaft and axially moves with the shaft. The stripper arm's distal end is adjacent to the reverse punch and recessed from the cutting edge of the reverse punch. An actuator causes the distal end of the stripper arm to move to a position located radially outward from the cutting surface when a trimmer ring from the neck of a bottle is to be removed from the apparatus.
