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.

Abstract: A preform mold (100) including a core plate (210), a cavity plate (410) and a plurality of mold stacks (MS) mounted between the core and cavity plates (210, 410). Each mold stack (MS) includes a core insert (250) mounted to the core plate (210), a cavity insert (440) mounted to the cavity plate (410) and split mold inserts (350) mounted between the core and cavity inserts (250, 440). The core inserts (250) are mounted to the core plate (210) by fasteners accessible from a rear side of the core plate (210). When the mold (100) is assembled, the core inserts (250) can be secured by the fasteners in a fixed condition in which they are immovable relative to the core plate (210). Also disclosed is a method of aligning the core inserts (250) by securing the core inserts (250) from a floating condition, in which they are able to slide relative to the core plate (210) along a sliding interface therebetween, to the fixed condition.

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.
