<p>A method and apparatus for automatically setting the die height platen (34) on a toggle-operated injection molding machine (10) to achieve a desired mold clamping force. A control (180) is provided and contains information relating a desired clamp tonnage with a toggle crosshead displacement, in order to permit setting the die height platen (34) for a particular set of molds (26, 28) so that the clamp (16), when operated, will automatically provide the desired clamping force between the mold members (26, 28). The adjustment is provided by moving the die height platen (34) in response to deviations from a predetermined set of conditions, the die height platen (34) being moved by an hydraulic motor (70) and chain drive (74) to shift the die height platen (34) along guide rods (24) that extend between the die height platen (34) and a stationary mold platen (18).</p> |
