Injection-moulding machine for producing plastic parts by the injection-moulding or reaction injection-moulding method

摘要

The invention relates to 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 associated injection unit for the simultaneous injection of the molds. The apparatus further includes two outer mold clamping plates, one of which is arranged on guide elements and movable thereon in the locking direction, and a center mold-holding part movably arranged on guide elements between the two mold clamping plates. The mold-holding part is provided with a heatable melt conduction system with sprue nozzles and has one half of a mold attached to each of its two sides. The center mold-holding part is designed as a mold clamping plate sectioned lengthwise in three parts relative to the locking direction. The parts of the sectioned mold clamping plate are kept together by a high-speed clamping device and have the melt conduction system arranged between the three parts so that it is possible to connect each melt conduction system to an injection unit and inject the associated mold separately or two different molds can be injected simultaneously.
