How to make a rough adjustment of the Blow molding machine?

Loosen the 4 front nuts of the tie rod and its pressure plate, so that the adjustment plate moves backward. At this time, the rear end of the sprocket screw is tightly fixed to the rear pressure plate of the mold adjustment nut of the adjustment plate. This eliminates the gap between the sprocket nut and the rear pressure plate.

At the same time, since the front nut pressing plate of the tie rod is loosened, the tie rod moves forward under the drive of the reaction force of the sprocket screw, and the gap between the front nut and the fixed platen will increase. After confirming that all four tie rods move forward (the gap between the 4 front screws and the fixed plate is increased), tighten the front nut with uniform force and press the front nut pressure plate to complete the rough adjustment of the parallelism between the movable platen and the fixed platen.

Then, after quickly opening and closing the mold several times, in the state where the double toggle mechanism is fully extended, measure the distance between the movable platen and the four corners of the fixed platen, and calculate the parallelism.
