ABSTRACT OF THE DISCLOSURE There is provided an injection molding machine for the manufacture of plastic parts from thermoplastic, thermoset and/or elastomer material by injection molding or reaction injection molding. The machine includes a multi-station locking unit of horizontal or vertical configuration designed to hold a number of molds and an injection unit associated therewith for the simultaneous injection of the molds. The machine also includes two outer mold clamping plates, one of which is mounted on guide elements and movable thereon in the locking direction and a center mold-receiving part movably mounted on guide elements between the two mold clamping plates and having a heatable melt conduction system with sprue nozzles and one half of a mold attached to each of its sides. The center mold-receiving part is designed as a mold clamping plate sectioned lengthwise relative to the locking direction for receiving larger halves of a mold, the two parts of the plate being kept together by a high-speed clamping device and having the melt conduction system mounted between each other. Separate driving cylinders are attached to the center mold clamping plate. The melt conduction system has one or a plurality of separate melt conduction rails, each of which is rigidly clamped at its face side lengthwise relative to the direction of flow between the sectioned mold clamping plate so that uniform injection of both molds is assured regardless of expansion of the melt conduction system during heating. 0358K
