Husky Injection Molding Systems Ltd. | Date: 2017-01-11

A nozzle retention arrangement is provided for an injection molding manifold system, such as a hot runner manifold system. The nozzle retention arrangement couples an injection nozzle to a distribution manifold in a manner that locates the nozzle in its final operating position and applies an initial assembly load to retain the nozzle in position on the manifold to facilitate installation of a manifold system into a manifold plate. The nozzle retention arrangement may provide a compliant load application feature to limit sealing surface pressure between the nozzle and the manifold to prevent surface damage between the components, while also accommodating thermal expansion of the heated components during operation of the system. The nozzle retention arrangement may also provide a load control feature to prevent the machining quality of the nozzle bore in the manifold plate from determining the sealing load between the nozzle and the manifold.

A melt conditioner is provided. The melt conditioner includes a melt conditioning body having a plurality of melt conditioning channels. The plurality of melt conditioning channels are located upstream of at least one manifold flow channel. Each melt conditioning channel is for conveying, in use a melt sub flow and is dimensioned to provide, in use, a conditioned melt sub flow having a thermal profile that accounts for a downstream geometry of the manifold flow channel.

A method is provided of cleaning of a portion of a mold component, the portion of the mold component including a passage configured, in use, to allow passage of fluid and to prevent passage of melt, the method comprising: entering the mold component into a cleaning configuration, whereby a portion of the passage becomes part of a molding surface; performing a molding cycle to fill in at least the portion of the passage with molding material for incorporation and removal of a residue there from. Also provided is a mold having a first mold half and a second mold half, the halves being movable relative to each other. A mold shut height adjustment apparatus can provide for a change in the mold shut height.

An in-mold shutter (140) for embedding in an injection mold (100, 200, 300) is described herein. The in-mold shutter (140, 240, 340, 440, 540) includes a shutter actuator (148, 548) that is configured to selectively engage a first mold shoe (130) of the injection mold (100, 200, 300) with a platen of a mold clamping assembly (996) to hold the first mold shoe (130) in an extended position (E), along a mold-stroke axis (X), during a step of molding a first molded article (102A) in the injection mold (100, 200, 300). Also described herein is a molded article transfer device (150, 250) for use with the injection mold (100, 200, 300). The molded article transfer device (150, 250) includes a shuttle (154) that is slidably arranged, in use, within the injection mold (100, 200, 300). The shuttle (154) defines a first aperture (156A), at least in part, that alternately accommodates: (i) a first mold stack (106A, 206A, 306A) arranged therein; and (ii) a first molded article (102A) received therein with opening of the first mold stack (106A, 206A, 306A).

Disclosed herein is, amongst other things, a mold stack that includes a core insert, a core ring, and a split insert that are configured to cooperate, in use, to define a molding cavity. The core insert defines a ring seat on a medial portion thereof upon which the core ring may be seated, in use, in cooperation with a mounting interface thereon. The split insert defines a pocket that extends coaxially through a second projecting portion thereof within which to receive a projecting portion of the core ring. The core ring and the split insert being further configured to define a core ring-to-split insert parting line that is within the pocket of the split insert. The core ring further defines a first split insert seat for receiving the second projecting portion of the split insert.


Hot-runner manifolds that contain one or more types of non-melt channels in addition to melt channels, and injection-molding systems containing such hot-runner manifolds. The differing types of non-melt channels include: coolant channels for carrying a coolant for cooling the tips of hot-tip nozzles, for example, during hot latching operations; heating-fluid channels for carrying a heating fluid for heating melt within melt channels within the hot-runner manifolds; and actuation-fluid channels for carrying actuation fluid to valves of valve-actuated nozzles. In each case, nozzles can be formed unitarily monolithically with the hot-runner manifolds and one or more of the various types of non-melt channels can be continuously routed within such unitary monolithic nozzles. Freeform fabrication processes can be used to form hot-runner manifolds of the present disclosure, which often contain complex/intricate internal passageways that form the various types of melt and non-melt channels.
