摘要： Multiple nozzle injection molding apparatus wherein each heated nozzle is screwed into a socket in a mounting base secured in place adjacent a melt distribution manifold. Each heated nozzle extends through an opening in the manifold plate and has a nut-like engageable portion extending forwardly of the cavity plate. This allows each of the heated nozzles to be easily removed for cleaning or replacement without removing the cavity plate.

摘要： An apparatus and process for injecting molten plastic material includes a nozzle assembly through which plastic material flows and including a nozzle body with a heater affixed thereto. A mold cavity plate is positioned adjacent the nozzle body and is separable from the nozzle body so that separation of the mold cavity plate from the nozzle body exposes the nozzle body and permits removal of the nozzle body and the heater.

摘要： An injection molding nozzle with an outer collar portion extending around the rear end of an inner core portion. The nozzle has an electrical heating element with a helical portion extending in a spiral groove in the outer surface of the inner core portion. An integral one-piece construction is provided without having to overheat the heating element by the combination of the helical portion of the heating element being press fitted and reshaped into the groove and the outer collar portion and the inner core portion being secured together by a thermosetting ceramic sealant.

摘要： The present invention relates to an improved nozzle-manifold assembly having utility in injection molding machines for making molded plastic articles. The nozzle assembly employs a clamp ring to apply a clamping force to the nozzle housing to cause it to mate with a manifold so as to prevent leakage of molten plastic material between the nozzle housing and the manifold. The clamp ring is mounted to the manifold by a plurality of screws whose tightening creates the desired clamping force and an effective seal between the nozzle housing and the manifold. The nozzle-manifold assembly also includes a centering ring for positioning the nozzle housing within a bore in a mold plate.

摘要： An injection molding nozzle to be seated in an opening in a mold with an outer collar extending around an elongated central body. The outer collar is made up of two removable semicircular segments which interlock with the central body. Each of the semicircular segments of the collar have a pair of spaced locating and retaining lug portions which extend outwardly to a longitudinal ridge. This provides sufficient thickness for a threaded hole at each lug portion to receive a screw to tighten the rear end of the nozzle securely against a melt distribution manifold. The ridges of the lug portions fit in contact in the opening in the mold to precisely locate the rear end of the nozzle and retain the two semicircular segments in the interlocking position.

摘要： An injection molding nozzle and method of making it having an electrical heating element extending in a pair of alternating coils in a spiral channel around a central melt passage. The heating element has a U-shaped bend near the forward end of the nozzle and two ends at an external terminal near the rear end. A central wire in the heating element has a fine coiled heating portion extending between two larger diameter conductive portions which extend to the terminal. One of the conductive portions of the central wire is a predetermined length longer than the other and extends in one of the alternating coils of the heating element along a rear portion of the nozzle adjacent the terminal. The heating portion of the wire extends in both of the alternating coils of the heating element along a forward portion of the nozzle so the heating element provides substantially less heat along the rear portion than along the forward portion of the nozzle.

摘要： This invention is an improved injection molding nozzle whereby the shut-off plunger is operated by a fluid and the opening of the nozzle is accomplished by the flow of plasticized material through the nozzle. A control rod internal to the nozzle controls the movement of the plunger shut-off member and is adjustable so that the amount of plasticized resin flowing through the nozzle can be accurately controlled.
