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.

Molding system having a mold stack with a cleaning configuration and a shut height adjustment mechanism

There is provided a structure for positioning a first mold part of a mold on a mold mounting face in an injection molding machine. The structure comprises a positioner configured to connect the first mold part to part of the injection molding machine, wherein the positioner is adjustable to position the first mold part on the mold mounting face. The structure further comprises controller executable instructions executable in a controller with which to resolve an alignment parameter of the mold using a feedback signal from a sensor. Further provided is a method of operating an injection molding machine which method comprises the steps of positioning a first mold part of a mold on a mold mounting face using a positioner and appreciating an alignment parameter of the mold with reference to a feedback signal from a sensor.

Mold positioning device

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.

Molding system with movable split mold inserts

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.

Disclosed herein, amongst other things, are structure and steps for positioning a first mold part of a mold on a mold mounting face in an injection molding machine. In particular, the structure and steps may include a positioner that is configured to connect the first mold part to part of the injection molding machine, wherein the positioner is adjustable to position the first mold part across the mold mounting face.

There is provided a member of a mold stack (), the member comprising: a member body () defining a member molding surface for defining, in use, a portion of a molding cavity for molding a molded article, a member cooling circuit () having a plurality of member cooling channels (), the plurality of member cooling channels () being coupled in parallel to a source of cooling fluid, the member cooling circuit () being fully encapsulated within the member body ().

Mold component

Lock ring for use in a mold stack

Disclosed herein is, amongst other things, a molding apparatus that includes a core ring () that is configured to seat, in use, around a core insert () in a mold stack (). The core ring () is configured to be received, at least in part, within a pocket () that is defined within a split insert () of the mold stack (). The core ring () is also configured to define at least a portion of a molding cavity () having a core ring-to-split insert parting line () that is within the pocket () of the split insert ().

Molding apparatus

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 () for use in a first stack portion () of a mold stack (). The lock ring () includes a tubular body () that is configured to define, amongst other things, a support interface () in cooperation, in use, with a split insert () of the first stack portion through which a compressive load is transferrable during molding of the preform, wherein the support interface () includes a support shelf () that is defined, at least in part, on a first major promontory () of the tubular body ().

There is provided a stripper assembly () for use in a mold stack () for forming a preform () suitable for blow-molding into a final-shaped container. The stripper assembly () comprises a stripper plate () connectable, in use, to a stripper plate actuator; neck rings () configured to cooperate to define a portion a neck region () of the preform (); a stripper ring () configured to define at least a portion of a top sealing surface of the neck region () of the preform (); the stripper plate () being configured to actuate the neck rings () and the stripper ring (), in unison, along substantially the whole length of a complete ejection path, which is substantially parallel to a longitudinal axis of the mold stack (); and wherein the neck rings () are configured for movement in a direction substantially perpendicular to the longitudinal axis of the mold stack, over at a portion of the complete ejection path, the stripper ring () having an air channel () configured to directed a flow of fluid towards the preform.
