摘要： Crown-flash-reduction systems, methods, and apparatuses for actively reducing the likelihood of formation of crown flash on injection-molded objects. The active reduction includes moving at least one of a valve member and a mold gate periphery in a manner that actively weakens or separates molding material present in a molded object from molding material present in the closed mold gate prior to or in conjunction with de-molding the molded object.

摘要： 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.

摘要： An injection molding machine includes an edge gate nozzle with a nozzle body having a primary melt channel and a nozzle head having first and second secondary melt channels that feed melt to first and second nozzle tips. First and second heaters are disposed in the nozzle head to provide heat to the secondary melt channels. In some embodiments, the heaters are positioned adjacent to the secondary melt channels, with first heater is closer to the first secondary melt channel than to the second secondary melt channel. In some embodiments, the heaters are positioned adjacent to the nozzle tips, with the first heater closer to the first nozzle tip than to the second nozzle tip. In some embodiments, each heater is adjacent to both the respective nozzle tip and secondary melt channel. In some embodiments, each heater is individually controllable.

摘要： A unitary monolithically formed hot-runner apparatus having at least a manifold containment structure, a hot-runner manifold, at least one nozzle, and one or more spacers. In some embodiments, the manifold containment structure, hot-runner manifold, nozzle(s), and spacer(s) may be multi-material apparatuses of unitary monolithic construction. In other embodiments, a thermal expansion accommodation portion is provided for each nozzle to accommodate thermal growth. Each spacer may be formed of a material having a lower thermal conductivity than the materials of the hot-runner manifold and manifold containment structure and may be made to include a discontinuity to allow for thermal expansion.

摘要： 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.

摘要： An apparatus and method of coupling and decoupling a valve stem to an actuator are disclosed. In one embodiment, the actuator includes a moveable member that is coupled to the valve stem. One of the valve stem and the moveable member is a male coupling portion and the other of the valve stem and moveable member is the female coupling portion. The male coupling portion is nested within the female coupling portion. A retaining pin retains the male coupling portion with respect to the female coupling portion.

摘要： A method and apparatus for equalizing gate pressure of a hot runner nozzle are disclosed. The nozzle includes a nozzle housing defining a primary melt channel, a first nozzle tip having a first secondary melt channel in fluid communication with the primary melt channel, a second nozzle tip having a second secondary melt channel in fluid communication with the primary melt channel, and a valve disposed in the primary melt channel for selectively opening and closing a downstream end of the primary melt channel to control a flow of melt to the first and second secondary melt channels. In some embodiments, the valve is configured to selectively open when a pressure of the melt reaches a threshold peak pressure. In some embodiments, the valve includes a valve stem that cooperates with the primary melt channel to block a flow of melt therefrom until the threshold peak pressure is established.
