ABSTRACT:
Jack-up bolts are provided at two places along the rear platen movement direction on both sides of a lower part of a rear platen of an injection molding machine. The jack-up bolt engages threadedly with a bolt hole formed in the rear platen, and a lower end face of the jack-up bolt abuts on the upper surface of a slide plate to support the rear platen. A fixing bolt is inserted in a through hole formed in the jack-up bolt, and is threadedly engaged with a tap hole provided in the slide plate, by which the rear platen and the slide plate are integrated. The rear platen moves while being supported by the slide plate. When the tilt of the rear platen is corrected, the fixing bolt is loosened and the jack-up bolt is turned, by which a distance between the rear platen and the slide plate is adjusted.
