    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: A controller includes an operation information acquisition unit that acquires operation information, a characteristic information acquisition unit that acquires characteristic information of heat dissipation characteristics of a heater, a surface temperature acquisition unit that acquires the surface temperature of the heater, and a results information acquisition unit that acquires results of a transition in the ratio of the surface temperature and a set temperature with respect to a transition in the heater output as results information. The controller also includes an estimation unit that uses the operation and results information, and the acquired surface temperature to estimate the surface temperature of the heater, and an energy quantity calculation unit that uses the estimated surface temperature and characteristic information to calculate the heat quantity dissipation from the surface of the heater and calculates heat transfer energy quantity transmitted from the heater to a resin and the shear energy quantity.

    摘要: A plasticizing unit is provided for an injection unit of an injection moulding machine with a support element arranged beneath the cylinder and connected therewith. To simplify adjusting of the nozzle centre, a fixing element surrounds the end of the support element facing away from the cylinder such that a distance is present between the fixing element and the support element. Several adjusting elements are provided, to produce a force-fitting and/or form-fitting connection between the fixing element and the support element to adjust the position of the support element relative to the fixing element in a plane orthogonally to the cylinder axis. The plasticizing unit can be clamped in and out with its fixing element in a clamping- and positioning system connected with the machine bed. On changeover of the plasticizing unit, an adjusting of the nozzle centre, which has been carried out once, is retained.

    摘要: An injection unit for a shaping machine includes a plasticizing cylinder which has a collar and a carrier portion which has a trough. The plasticizing cylinder is arranged in the trough, and an axial movement of the plasticizing cylinder relative to the carrier portion is restrained in positively locking engagement by the collar bearing against the carrier portion. A clamping element which is fixed or shaped on the plasticizing cylinder is fixed by fixing elements to the carrier portion in such a way that the plasticizing cylinder is braced between the trough and the clamping element. The plasticizing cylinder is braced by bracing elements against lifting of the collar off the carrier portion in an axial direction of the plasticizing cylinder.

    摘要: An injection molding system and method of operating the system are disclosed. The system may include a hopper, a barrel configured to receive injection material from the hopper, a screw disposed within the barrel, and a mold defining a mold cavity configured to receive the injection material from the barrel. A pressure-balancing conduit may connect the mold cavity and a rear end of the barrel and be configured to allow air to flow from the mold cavity to the rear end of the barrel. A mold valve may be disposed between the pressure-balancing conduit and the mold cavity and a barrel valve may be disposed between the pressure-balancing conduit and the rear end of the barrel. The method may include opening the mold valve and injecting a material into the mold cavity from the barrel.
