    摘要: A nozzle tip for guiding a valve pin of a nozzle for injecting molten material into a mold during injection molding is described.
    The nozzle tip consists of an outer member, provided with an axial pass-through cavity, which at one end comprises a central pass-through conduit for the exit of the molten material, an inner member, having an axial pass-through cavity, which is coaxially mounted within the outer member and comprises a tapered tip with a hole to direct the molten material to the central conduit, and an annular-shape insert made of wear-resistant material, with a central pass-through cavity into which the valve pin can slide and mounted in correspondence with the central pass-through conduit.
    To prevent or mitigate wear, the central pass-through cavity of the insert is constituted of the juxtaposition of a cylindrical-shape cavity portion and a conical-shape cavity portion, and the insert is a separate piece and directly interposed between the tapered tip of the inner member and an inner surface of the outer member so that said tapered tip abuts against the inlet of the conical-shape cavity portion at a zone of mutual contact.

    摘要: An injection molding apparatus for receiving molten material from an injection nozzle and delivering the molten material to a mold cavity is disclosed. The injection molding apparatus includes a molten material conduit device for receiving the molten material and directing the molten material to a molten material receiver defined by a manifold, the manifold directing the molten material the mold cavity housed within the mold assembly of the apparatus. The molten material conduit device includes a manifold-sealed interface effector for sealing against the manifold, and a back plate engager for engaging the back plate that secures the molten material conduit device to the manifold. The manifold, the molten material conduit device and the back plate are cooperatively configured such that a discharge end of the conduit device is sandwiched between the manifold and the back plate and such that the discharge opening is disposed in alignment with the molten material-receiver.

    摘要: Resin supply system in which resin material is stored in a pouch in a degassed state ready for use. The pouch comprises a body portion forming a reservoir for resin material and a connector portion in fluid communication therewith. The connector portion includes an outlet which is configured to be connected to an injector head of an injector assembly, the injector head being connectable to a mould by means of connecting tubing to provide a resin supply thereto. The pouch is configured to be mountable in a housing of the injector assembly and is compressed by hydrostatic pressure of water surrounding the pouch in a chamber of the housing. The application of pressure by a piston moving in a direction transfers pressure to the water and then to the pouch in a controlled manner to provide the resin supply to the mould. After use, the pouch is removed and discarded thereby substantially eliminating the need for cleaning of the housing after use.

    摘要: A plasticizing device includes a plasticizing mechanism including a feeding port for receiving a material and configured to plasticize the material to generate a melted material and a material feeding mechanism configured to feed the material to the plasticizing mechanism. The material feeding mechanism includes a housing including a depositing port communicating with the feeding port, the housing storing the material, and a rotating member housed in the housing and capable of rotating along an inner edge of the housing. A plurality of through-holes are provided in the rotating member at intervals along an outer circumference of the rotating member. When the rotating member rotates and any one of the plurality of through-holes and the depositing port communicate, the material stored in the housing is fed from the feeding port to the plasticizing mechanism through the depositing port.

    摘要: A hot runner system having a nozzle received in a well in a mold plate. The nozzle has a melt channel, a nozzle body through which the melt channel extends, and a collar connected to and spaced apart from the nozzle body. A manifold is seated against the nozzle. The manifold has a melt channel in fluid communication between a source of moldable material and the nozzle channel. A bearing member against which a seating surface of the collar is supported is received in the well, and a biasing member is seated between a step in the well and the bearing member. The biasing member has plate loading surface and a nozzle loading surface. The nozzle loading surface and the plate loading surface are concentric with the seating surface of the collar and are circumferentially offset from the seating surface of the collar in opposite directions.
