摘要： An injection molding apparatus having a nozzle which includes a first nozzle body segment, a second nozzle body segment, and a thermal barrier coupled between the nozzle body segments. The first nozzle body segment, the thermal barrier, and the second nozzle body segment define a melt channel through the nozzle for delivering a melt stream from a manifold channel of a manifold to a mold cavity. The thermal barrier substantially limits the heat flow from one nozzle body segment to the other, to thereby control the heat distribution along the melt channel.

摘要： This invention provides an improved heating apparatus for controlling the temperatures of the resin melt that is pressure fed to a molding cavity comprising a heating jacket 30 comprising the concentric tubular elements; a copper sheath 32 having an inside surface 34 and an outer surface 36, a retainer sleeve 40 and coiled heating element 42 sandwiched between the sheath 32 and the retainer sleeve 40. The inside surface of the sheath 32 is formed with at least one circumferential groove 38 which provides an insulating air gap so that a lesser amount of heat is conducted to the central portion of the heating jacket 30 thereby creating three distinct temperature zones. The outer surface 23 of the nozzle 22 is provided with a longitudinal groove 46 extending down its outside surface between the sheath 32 and the nozzle housing 22 for the hot runner conduit 24. A thermocouple sensor cable 52 is received in the longitudinal groove so that the thermocouple sensor 50 is strategically positioned adjacent the gate well section 28 to maintain the temperature of the resin melt entering the cavity.

摘要： A sealing arrangement between hot runner components includes a sealing component positioned between a first hot runner component and a second hot runner component having a molding material channel extending therebetween. The sealing component includes an opening through which the molding material channel extends. The sealing component is received in a bore in the second hot runner component such that a portion of the sealing component projects beyond the second hot runner component to create a gap between the first hot runner component and the second hot runner component. The sealing component has a hardness that is greater than a hardness of the second hot runner component and less than a hardness of the first hot runner component. Further, the sealing component has a coefficient of thermal expansion that is proximate to a coefficient of thermal expansion of the second hot runner component.

摘要： A nozzle for an injection molding apparatus includes a nozzle body having a first nozzle body segment, a second nozzle body segment and a third nozzle body segment. The second nozzle body segment is removably connected to at least one of the first nozzle body segment and the third nozzle body segment. The first nozzle body segment and the third nozzle body segment are heated either by first and second nozzle heaters, respectively, or by a heater sleeve having a cut-out along the length of the second nozzle body segment. The second nozzle body segment is substantially devoid of a nozzle heater such that the second nozzle body segment is heated passively through contact with the first nozzle body segment and the third nozzle body segment.

摘要： A nozzle has a tubular metal core which forms a central injection duct, and a cylindrical, outer, lateral surface. A heater/diffuser device includes a metal heat diffuser of tubular cylindrical shape with an open annular cross-section, mounted around the cylindrical surface of the core. The diffuser has: a cylindrical internal surface fitting the cylindrical surface of the nozzle core, two facing longitudinal free edges which are spaced apart circumferentially, are free of one another, and define between them a longitudinal space extending along a generator line of the cylindrical surface of the diffuser, and a recessed, channel-like seat formed in a surface of the diffuser element. A resistor is housed in the channel-like seat. The distance between the longitudinal free edges is such that, when the nozzle unit is heated by the supply of electrical current through the resistor, the diffuser is free to expand thermally by extending in the circumferential direction around the nozzle without moving radially away from the outer surface of the nozzle core.

The first melt channel is adapted to be downstream from and in fluid communication with a melt source. The nozzle body has a downstream nozzle body end. The nozzle body is made from a nozzle body material. The heater is thermally connected to the nozzle body. The insert is positioned in the nozzle body. The insert is made of an insert material. The insert material is more thermally conductive than the nozzle body material. The insert is adapted to conduct heat from the heater towards the downstream nozzle body end.
