ABSTRACT:
A mold clamping unit comprises guide rollers for guiding fitting and releasing of a mold, a hydraulic clamp for holding the mold at a molding position, a guiding portion formed to project in a direction perpendicular to a mold open-close direction from a lower portion of platen and a locking mechanism provided to an upper portion opposing to the guiding portion for the platen, for locking the mold at a releasing position. Since exchange and maintenance operations of a stamper can be carried out under a condition where the mold is released to the releasing position over the guiding portion and locked by the locking mechanism, fitting/releasing of the mold to/from the platen can be facilitated and exchange and maintenance operations of the stamper can be made easy.
