ABSTRACT:
A fixed platen and a rear platen of an injection molding machine are connected to each other via tie bars. A coil spring is disposed between the tie bar and the rear platen such that the rear platen is urged in a direction away from the fixed platen. A mold thickness adjusting member such as a nut is also provided for causing the rear platen to move along the tie bar toward the fixed platen against the resilience of the urging means.
