Abstract
An injection molding machine has a die-height adjustment system. External screws formed individually on four tie-bars and die-height adjusting nuts threadedly engaged therewith are configured to be rotated independently with one another. In processes prior to mold clamping, the die-height adjusting nuts are rotated so that movable and stationary platen surfaces maintain a desired parallelism. During mold clamping, the die-height adjusting nuts are rotated so that clamping forces produced by the tie-bars are in a desired balance.
