Apparatus for the manufacture of plastic parts by injection molding or reaction injection molding

A nozzle system for an apparatus having a plurality of molds and a locking unit used in the manufacture of plastic parts from thermoplastic, thermoset and/or elastomer material by injection molding or reaction injection molding, an injection unit associated with said nozzle system for the simultaneous injection of the molds, a two-part movable center mold clamping plate sectioned crosswise relative to the locking direction, the two parts of said mold clamping plate being kept together by a high-speed clamping device and having a melt conduction system disposed between the two parts, the melt conduction system having one or a number of separate melt conduction rails, each being rigidly clamped on its face side between the sectioned mold clamping plate lengthwise relative to the direction of flow of the melt, and a median centering collar and a widened melt inlet with rounded side walls adapted to receive said nozzle system arranged on a flange of the melt conduction rail, said nozzle system comprising:

• a spacing ring with a torpedo, a right-angled adapter and a cut-off nozzle exchangeably joined with each other to form a rigid unit carefully secured on the movable center, sectioned mold clamping plate by said high-speed clamping device.
