Abstract
A closing unit for an injection molding machine includes first and second platens, of which at least one is movable, and an intermediate plate disposed between the first and second platens. A molding tool is disposed between one of the first and second platens and the intermediate plate. In order to allow operation of the closing unit with intermediate plate also as a single-face mold for molding a single-component product, the molding operation between the other one of the first and second platens and the intermediate plate is disabled by a dummy tool or by securely fixing the intermediate plate to the other one of the first and second platens. Removal of an end product from the molding tool is realized by at least one ejector which is arranged in or on the intermediate plate.
