    Abstract: A cavity plate assembly (400) for a preform mold (100), which includes a cavity plate (410) having an array of seats (412) and a corresponding array of cavity inserts (440) mounted to a front face (CVF) of the cavity plate (410) and in communication with a respective seat (412). Each cavity insert (440) includes a body (441) with a mounting face (441a) and a spigot (443) projecting from the mounting face (441a) and received in a respective seat (412) of the cavity plate (410) such that the mounting (441a) face abuts the front face (CVF) of the cavity plate (410). Each cavity insert (440) also includes a molding surface (448) along its length, at least two thirds of which extends beyond the cavity plate (410).

    Abstract: An injection mold (100) including a core plate assembly (200), a cavity plate assembly (400) and a stripper plate assembly (300) arranged between the core and cavity plate assemblies (200, 400). The mold (100) includes a plurality of mold stacks (MS) with a molding configuration, in which the mold stacks (MS) are closed to define molding cavities. A gap (G) is provided between the core plate (210) and the stripper plate (310) when the mold (100) is in the molding configuration, such that a clamping load (CL) applied to urge the core plate (210) toward the cavity plate (410) is directed substantially entirely through the mold stacks (MS).

    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. In another aspect, a mold shut height adjustment mechanism may include a mold component movable along an operational axis of the mold, a stop member, movable along the axis relative to the mold component, having first and second stops for providing first and second gaps on the front and back sides, respectively, of the mold component when the stop member is deployed, and a spacer for use in selectively deploying the stop member.
