  • Patent number: 11826936
    Abstract: In an aspect, a mold stack may comprise two adjacent components, one at least partially defining a vent adjustable between a molding configuration and a cleaning configuration. A junction of the components may be adjustable between a molding configuration, wherein mating faces contact one another to define a parting line, and a cleaning configuration, wherein mating faces are separated to create a molding cavity extension therebetween and an auxiliary melt barrier prevents uncontrolled flashing from the extension.

  • Patent number: 11607830
    Abstract: Disclosed herein, amongst other things, is, a stripper assembly operable to eject a molded article from a mold that includes slides that are movable laterally relative to each, a first split mold insert inter-connected to a first slide and a second split mold insert inter-connected to a second slide. The system being operable such that when the first and second slides are in the closed position, the first and second split mold inserts form at least a portion of the molding cavity; the system being operable such that such during operation of the injection molding system, the first split mold insert is movable relative to the respective first slide and the second split mold insert being movable relative to the second slide.

  • Patent number: 8956150
    Abstract: Disclosed herein is, amongst other things, a molding apparatus that includes a core ring (140, 340, 440, 540, 640, 740) that is configured to seat, in use, around a core insert (120, 320, 420, 620) in a mold stack (116, 216, 316, 416, 516, 616, 716). The core ring (140, 340, 440, 540, 640, 740) is configured to be received, at least in part, within a pocket (152) that is defined within a split insert (150) of the mold stack (116, 216, 316, 416, 516, 616, 716). The core ring (140, 340, 440, 540, 640, 740) is also configured to define at least a portion of a molding cavity (119) having a core ring-to-split insert parting line (180) that is within the pocket (152) of the split insert (150).

  • Patent number: 8944808
    Abstract: Disclosed herein are, amongst other things, a molding apparatus with which to mold, in use, a preform of a type for blow molding into a container. The molding apparatus includes a lock ring (104, 204) for use in a first stack portion (108) of a mold stack (120). The lock ring (104, 204) includes a tubular body (150, 250) that is configured to define, amongst other things, a support interface (194) in cooperation, in use, with a split insert (6, 106) of the first stack portion through which a compressive load is transferrable during molding of the preform, wherein the support interface (194) includes a support shelf (154) that is defined, at least in part, on a first major promontory (152, 252) of the tubular body (150, 250).
