Mold clamping control method of injection molding machine with toggle type clamping mechanism

摘要

At the start of injection filling, a low-pressure type fastening process that performs position maintenance control to maintain the position of the cross head 25 in the set holding position while the toggle link is bent, and the cross head ( 25) The crosshead has a compression press process so as to control the speed and position of moving forward from the set holding position to the set advance position, and in at least part of the compression press process, the generated output of the drive unit maintains the first output upper limit. The advancement of (25) is achieved by the mold clamping control method of the injection molding machine with a toggle type clamping mechanism that continues.
