Injection Molding Machine Tie Bar Adjustment

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.

Each tie-bar-less clamping unit is aligned precisely prior to delivery using the highly sensitive platen parallelism adjustment mechanism. Because the patented force divider is preloaded with tension, platen parallelism remains constant even when the mould is mounted. No turning and no tilting.

Poor maintenance; everything mechanical in a die casting machine or injection molding machine including the machine linkage, tie bars, tie bar nuts and platens are wearing; as an example the threads on the die height nuts actually wear from the continuous loading and unloading of the machine, these worn threads cause "slop" between the tie bars ...

(1) The operation of the injection molding machine needs to be stopped to adjust the effective lengths of the tie bars, and molded products cannot be manufactured during the adjustment. (2) Although the tie bar is fixed by any fixing means so that it is not rotated during the normal operation, it is necessary to disassemble the fixing means and to release the fixation during the time of performing the adjusting …
