  • Patent number: 10913192
    Abstract: Thermocouples and their associated thermocouple junctions can be integrated via freeform fabrication into various parts of injection-molding apparatuses, including the nozzles. Unitary monolithic integration of thermocouples allows thermocouple junctions to be located highly proximate to the locations where temperature monitoring is desired, particularly, near the tips of injection-molding nozzles, which has conventionally been difficult or impossible to achieve. An injection-molding nozzle with one or more integrated thermocouples, a hot-runner manifold with injection-molding nozzles, having integrated thermocouples, monolithically integrated with the manifold as a single part using a freeform fabrication process, and a separately formed injection-molding nozzle having at least one integrated thermocouple and a robust electrical connection are presented according to various aspects of the invention.

  • Patent number: 10882233
    Abstract: An apparatus and method for actuating a valve stem between an open position and a closed position and for taking one or more valve gated nozzle out of service is disclosed. The hot runner includes a valve gated nozzle having a valve stem, the valve stem coupled to a piston that is held against an actuation plate via pressurized air. When a valve stem becomes stuck in a gate of the hot runner, the actuation plate can continue to move while the piston remains stationary. The valve stem may also be protected from an over force situation such as if the valve stem encounters an obstruction as the actuation plate is moving toward the closed position.

  • Patent number: 10870229
    Abstract: A mold stack for a mold comprises a mold core configured for reception in a mold cavity plate with an outer molding surface. The mold core comprises an inner core with a first tapered guide surface and an outer core with a second tapered guide surface. The inner core is received through a passage in the outer core. A spacer slidably supports the outer core on the inner core. The outer core is movable relative to the inner core between a molding position in which the inner and outer cores define a mold cavity with the outer molding surface, and an open position in which the outer core is extended relative to the inner core. In the molding position, the first and second tapered guide surfaces engage one another to align the inner and outer cores.

  • Patent number: 10766176
    Abstract: 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.

  • Patent number: 10703034
    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.

  • Patent number: 10160148
    Abstract: 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.
