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.
A nozzle retaining clip for retaining a nozzle assembly with a material distributing manifold to facilitate installation of a pre-assembled construction of a manifold and nozzle assembly in a mold assembly component, the manifold comprising a manifold member comprising a manifold passage for conveying material in a flowable condition, each nozzle assembly comprising a nozzle passage there-through for conveying material from the manifold passage to a mold cavity, the nozzle retaining clip comprising an attachment portion by which the clip is attached to the manifold member and an engagement portion for engaging a nozzle assembly abutted to the manifold member, wherein a pair of clips are locatable so that the respective engagement portions thereof engage opposite sides of a nozzle assembly abutted to the manifold member so as to allow the manifold member and nozzle assembly to move relative to one another while the engagement portions of the clips remain engaged with the nozzle assembly.
An apparatus for injection molding comprising a material distributing manifold, at least one nozzle assembly and at least one pair of nozzle retaining clips for retaining at least one nozzle assembly with the manifold, the nozzle assembly being held in abutting contact with the manifold by the pair of clips so that the nozzle assembly and manifold can move relative to each other while abutted and while the nozzle retaining clips remain engaged with the nozzle assembly.
