    摘要: A nozzle comprises a nozzle housing having a preload engagement surface, a nozzle tip, a tip retainer having a preload engagement surface that retains the nozzle tip against the nozzle housing, and a preload limiter gap between the tip retainer and the nozzle housing comprising a spaced distance between the preload engagement surfaces when the nozzle is in a first position and a second position that creates a desired amount of preload force P when the nozzle is in the second position. In another embodiment, a nozzle comprises a nozzle housing, a nozzle tip, and a tip retainer movable with respect to the nozzle tip along the nozzle housing and that retains the nozzle tip against the nozzle housing. A tapered interface disposed between the tip insert and the tip retainer at an angle greater than or less than 90 degrees with respect to a longitudinal axis of the nozzle.

    摘要: The injection nozzle includes a longitudinal flow channel, a plurality of angular channels extending from the longitudinal flow channel (1) in a first direction at an acute angle with respect to the longitudinal axis of the nozzle, and (2) in a second direction at an acute angle with respect to the first direction, an annular channel extending from the angular channels, and a passageway extending from the annular channel to the injection orifice, wherein the angular channels cause a swirling action in the annular channel to flush out resin from the annular channel.
