Abstract
The present invention aims to stably maintain the posture of a crosshead by means of guide bars without an increase in the size of a link housing or tie bars. An opening/closing apparatus according to the present invention includes: a pressure-receiving plate (); a fixed platen () to which a fixed mold () is to be mounted; a frame () on which the pressure-receiving plate () and the fixed platen () are installed; and a movable platen () which is movable on the frame () and to which a movable mold () is to be mounted. The opening/closing apparatus also includes: a crosshead movement mechanism including guide members () extending from the pressure-receiving plate (), and a crosshead () whose movement is guided by the guide members (); an opening/closing mechanism for opening/closing a mold, including a toggle link mechanism () connecting the pressure-receiving plate (), the crosshead () and the movable platen (), and a drive mechanism for driving the toggle link mechanism (); and a guide member support mechanism for supporting the guide members (). The guide member support mechanism has support portions () which are slidable on the upper surface of the frame ().
