  • Patent number: 6514452
    Abstract: A molding system has a slide displaceable parallel to an axis through a relatively long stroke relative to a stationary overhead extruder head, a center support fixed on the slide, and a pair of end supports displaceable axially through relatively short strokes on the slide between inner and outer end positions. A pair of inner mold halves carried on the center support are directed axially oppositely therefrom toward the end supports. Respective outer mold halves carried on the end supports are axially engageable with the respective inner mold halves in the inner positions of the end supports. An end-support drive connected between the slide and the end supports moves the end supports between their end positions and a slide drive connected to the slide moves the slide axially relative to the head. Each of the end-support drives includes a respective motor mounted on the slide.

  • Patent number: 6418754
    Abstract: A method for heated mold changing at a forming station (24) is performed by apparatus (32) in a heated chamber (22) where heated glass sheets are cyclically formed. A switching station (318) is located adjacent the forming station (24). An unloading station (320) and a mold preheating station (322) are each located adjacent the switching station. An unloading cart (324) is initially movable from the loading station (320) to the switching station (318) and then to the forming station (24) to receive one or more heated molds from the forming station and is subsequently moved from the forming station back through the switching station to the unloading station to permit unloading of each heated mold. A loading cart supports a second mold or a pair of molds for heating within the mold preheating station (322) and is movable from the mold preheating station to the switching station (318) and then to the forming station for mold loading.

  • Patent number: 6299428
    Abstract: A method and apparatus for compression molding plastic articles such as closures include a plurality of tools mounted in opposed pairs with the tools of each pair including opposed male and female mold sections. The tool pairs are mounted for motion in an endless path. The tool pairs and associated mold sections are closed during motion in the path for compression a molding charge in the mold cavity formed between the mold sections of each pair, and opening the mold cavity to release an article formed between the mold sections. A latch mechanism is associated with each pair of tools for holding the tools and mold sections in the closed position during motion in the path independent of the mechanism for closing the tools and mold halves. In this way, forces imparted to the mold halves and tools to hold the mold closed are isolated from the machine frame. The latch mechanism is selectively unlatched to permit opening of the mold halves and release of the article compression-molded between the mold halves.

  • Patent number: 6290482
    Abstract: The technical field of the invention broadly relates to molding systems, and more particularly to a flexible shoe assembly for use in a molding system. The clamp unit of a molding system includes a moving platen and a stationary platen supported by a frame. Tie bars interconnect the moving platen with the stationary platen. The tie bars are secured to the stationary platen and pass through respective openings in the moving platen. Each tie bar is supported and guided within their respective openings by a flexible shoe assembly and wear pad. The flexible shoe assembly has a force redirector for directing force away from a peripheral edge of the wear pad towards a central force area. The flexible shoe assembly also includes a load distributor to distribute the load across the wear pad surface. The flexible shoe assembly includes an upper support that is flexible about a lower support to keep the wear pad in operational contact with the tie bar.

  • Patent number: 6190154
    Abstract: In the case of an injection molding machine for processing plasticizable materials, a structural unit, which includes at least a movable mold carrier, a stationary mold carrier and a closing arrangement of a mold closing unit, is supported on support elements on a machine base. A pivotal axis, about which the structural unit is pivotable, extends transversely relative to a closing axis. A drive unit is provided for pivoting and for displacing the structural unit and is connected pivotally to the machine base and at an articulation point to the structural unit, which articulation point is disposed at a spacing from a pivotal axis. Upon transferring the structural unit from the horizontal position into the vertical position, the drive unit initially pivots the structural unit and then also displaces it.
