摘要： An injection mold characterized by relative simplicity, compact size, and capability of relatively high rate production of molded parts without runners which must be removed to finish the parts. A molten molding medium is fed to each mold cavity through a heated hot box and an injection nozzle contained within an injection chamber which communicates with the cavity through a gate opening in the cavity wall. The nozzle has a tip which enters the gate opening to define an annular injection orifice between the nozzle tip and the edge of the gate opening, and the nozzle seats slidably on the hot box to effect self-centering of the nozzle tip in the gate opening and sealing of the nozzle to the hot box by the pressure of the molding medium about the nozzle and heat transfer from the hot box through the nozzle to the medium to retain the latter at the proper molten temperature. The mold has mold cavities symmetrically arranged at opposite sides of the hot box and intersected by parting planes between mold sections which are separable to permit stripping of the molded articles from the cavities.

摘要： In various examples, a printbar is formed from multiple modular fluid ejection subassemblies joined together through a molding process that provides for a continuous planar substrate surface. A mold may secure the modular fluid ejection subassemblies during a molding process in which a runner conveys a molding material to seams between the joined modular fluid ejection subassemblies.

摘要： A stack molding apparatus is disclosed having a stationary mold platen and a movable mold platen defining a parting line. The apparatus has a melt transfer nozzle extending within a well in the stationary mold platen, the melt transfer nozzle defining a melt channel for receiving and transporting a melt stream. The apparatus also includes a melt transfer component having a spigot portion, a melt channel and an aperture in a sealing surface thereof, wherein the melt transfer component is fixedly attached to the stationary mold platen such that the sealing surface defines a portion of the parting line. The spigot portion is slidably fit within the melt channel of the melt transfer nozzle so that the melt channels are in fluid communication. When the stack molding apparatus is brought to an operating temperature, the melt transfer nozzle slides over the spigot portion to accommodate thermal expansion.

摘要： A crossover nozzle system for transferring molten plastic from an inlet at the center of the stationary platen of an injection machine to the main manifold of the molding chambers of the stack molds of the injection molding machine. The crossover nozzle system relies on molten plastic pressure within the system to actuate the primary sprue shut-off valve, and thus to open and close the flow of molten plastic to the molds. Therefore, a drool-free valve mechanism is created without needing an external actuation of the shut-off valve like, for instance, a hydraulic or a pneumatic cylinder.

摘要： To facilitate cleaning of melt channels in a runner system (102) in a centre-section carrier (20) or the like, a multi-piece interface adaptor (114, 116, 118) is detailed in FIG. 4. A male portion (114) of the interface adaptor (112) is securely coupled to the runner system (102) to extend the melt channel (63) thereof. The male portion (114) preferably includes a branching feature (124) that splits melt flow into opposing directions to feed distinct nozzles (60, 62). A female portion (116) of the interface adaptor includes bores (140, 142) that align with the branching feature (124, 134, 136) and support the mounting of nozzles (60, 62) therein. The female portion (116) is fixedly secured within the carrier (20). The male portion (114) and the female portion (116) are slidably engageable with one another along sealing surfaces (130, 220). At system operating temperatures, effective operational sealing occurs as a result of relative thermal expansion between the male portion (114) and the female portion (116). At lower temperatures, pulling of the runner system (102) along an axis aligned with its melt channel (63) permits the male portion (114) to be separated from the female portion (116) by disengaging the sealing surfaces (130, 220), thereby granting easy access to the melt channels and the branching feature (124) when the runner system (102) is removed from the carrier (20).

摘要： An expansion nozzle for conducting melt from a floating manifold to a mold assembly comprises a bushing having a bushing flange and spigot having a passage therethrough joining a nozzle inlet and an outlet, a head having a seating surface and a bore through the head slidably receiving the spigot so that the spigot is movable relative to the head over a range from abutting contact of opposing surfaces of the head and bushing flange to a limit of axial separation of the opposing surfaces, axial separation of opposing surfaces of the head and bushing flange being maintained throughout an operating temperature range. Springs maintain sealing contact of a seating surface of the head with a mating surface of the mold assembly. Advantageously, a locating ring provides a reaction surface for the springs and supports the head to resist moments arising from axial misalignment of the expansion nozzle and mold assembly.

摘要： A molding arrangement is provided for multi-level stack molds wherein mold sets and runners are made up of modular sections interchangeable individually or as larger assemblies for exchanging molds for one part for those for different parts or exchanging runners between hot tip and valve gate designs to accommodate different molding arrangements. The arrangement has discrete melt paths for each mold level, at least some of which extend around rather than through the mold levels and which incorporate readily separable connectors. This enables one set of molds and possibly as well the runners for one mold level to be interchanged without interfering with the mold and runner arrangement for an adjacent level.
