Patent ID: 7452199

Claim:
Apparatus for conveying melt to mold cavities, the mold cavities being defined by plural pairs of mating mold components, each mating mold component comprising a mold assembly, plural mold assemblies being supported so that mating mold components of the plural mold assemblies are simultaneously abutted and separated by movement of supports in a direction parallel to a mold longitudinal axis and the apparatus being abutted with and separated from at least one mating mold member with abutment and separation of mating mold components, the apparatus comprising at least one tubular body having a passage there through providing fluid communication between a source of melt and a plurality of mold cavities, an interface member mounted to at least one tubular body at a terminus of the passage for engaging a mating mold member and having a nozzle passage there through for conducting melt between the tubular body and the mating member, and a length adjusting device interposed between the interface member and the tubular body, the length adjusting device comprising a wedge member having a wedge first surface oblique to the longitudinal axis of the tubular body for abutting an adjustment surface and a wedge second surface perpendicular to the longitudinal axis of the tubular body, and means for setting the transverse position of the wedge member relative to the longitudinal axis of the tubular body to establish the position of the wedge second surface relative to the adjustment surface whereby the overall length of the combined tubular body and interface member is established.
