摘要： A nozzle controls flow of melt in injection molding equipment by passive actuation with opening and closing of a mold assembly. The nozzle comprises a valve pin having a pin passage therethrough movably supported within a nozzle passage and a contact arm transverse to and extending beyond the nozzle passage, the valve pin sealingly engaging the nozzle passage. Biasing means biases the valve pin to a closed position preventing passage of melt through the nozzle. The contact arm effects movement of the valve pin to an open position when closing of the mold assembly exerts a force on the contact arm to overcome the biasing means. A mold arrangement of plural mold assemblies comprises pairs of nozzles of the invention to control flow of melt through mating conduit segments between an injection unit and at least one mold assembly, the nozzles arranged and configured for seating engagement with abutment of the conduit segments.

摘要： An expansion nozzle for conducting melt from a floating manifold to a mold assembly comprises a bushing having a bushing flange and spigot having a passage therethrough joining a nozzle inlet and an outlet, a head having a seating surface and a bore through the head slidably receiving the spigot so that the spigot is movable relative to the head over a range from abutting contact of opposing surfaces of the head and bushing flange to a limit of axial separation of the opposing surfaces, axial separation of opposing surfaces of the head and bushing flange being maintained throughout an operating temperature range. Springs maintain sealing contact of a seating surface of the head with a mating surface of the mold assembly. Advantageously, a locating ring provides a reaction surface for the springs and supports the head to resist moments arising from axial misalignment of the expansion nozzle and mold assembly.

摘要： A nozzle retaining clip for retaining a nozzle assembly with a material distributing manifold comprises an attachment portion for attaching the clip to the manifold and an engagement portion for engaging a nozzle assembly abutted to the manifold. Two clips located to engage opposite sides of a nozzle assembly abutted to the manifold member are effective to retain the nozzle assembly and to allow the manifold and nozzle assembly to move relative to one another while the clips and nozzle assembly remain engaged. A first alternative clip achieves only surface contact and a second alternative clip allows protrusion of a segment of a nozzle assembly periphery through the clip. Advantageously, the clip comprises at least one locating tap to restrain movement of the clip relative to a manifold. An apparatus for injection molding comprises a manifold and nozzle assembly construction comprising clips in accordance with the invention.

摘要： A nozzle for controlling flow of melt in a mold assembly comprises a valve pin guide interposed between a nozzle inlet and nozzle outlet, a valve pin movably supported thereby, and a contact arm engaging the valve pin and transverse to and passing through the valve pin guide. Biasing means acting on the contact arm hold the valve pin in a position preventing flow of melt. As the mold assembly closes, forces exerted on the contact arm overcome the biasing means and allow the valve pin to move to a position permitting flow of melt. Relief of pressure of retained melt is effected when force therefrom exerted on the valve pin exceeds an adjustable pre-load of the biasing means. The nozzle advantageously comprises an inlet bushing movably supported by the nozzle body enabling adjustment of the overall length of the nozzle to accommodate a range of spacing of elements of the mold assembly.
