Injection molding machine mold adjusting method based on pull rod position and torque control

Abstract

The invention discloses an injection molding machine mold adjusting method based on pull rod position and torque control. The injection molding machine mold adjusting method comprises the following steps of installing mold clamping force testers on all pull rods of a horizontal injection molding machine, preliminarily setting mold clamping force corresponding to the mold clamping positions of all the pull rods of the horizontal injection molding machine, adding the mold clamping force of the mold clamping positions of the pull rods to obtain mold clamping tonnage corresponding to the mold clamping positions of the pull rods, establishing an initialization linear table on a mode adjustment control system, starting an automatic mold adjusting program of the horizontal injection molding machine, carrying out data calibration on the initialized linear table, modifying the mold locking tonnage of the pull rods at the mold locking position and torque value of the power output shaft of a driver in the initialization linear table into the actual mold locking tonnage of the pull rods at the mold locking position and the actual torque value of the power output shaft of the driver, repeating the above steps to carry out sequential progressive increase operation of the mold locking tonnage to obtain the accurate mold locking tonnage linear table, and carrying out mold adjustment. Automatic mold adjustment is simplified, mold adjustment period is shortened, and the stability and accuracy of the mold adjustment result are improved.

Description

technical field [0001] The invention belongs to the technical field of injection molding machine mold adjustment, and relates to an injection molding machine mold adjustment method based on pull rod position and torque control. Background technique [0002] At present, the automatic mold adjustment of injection molding machines uses electric eyes to judge and control the high-voltage end point. At the same time, the tonnage control range has large errors, and has not been tested by the clamping force tester, so the mold adjustment results are inaccurate. When the adjustment range of the tonnage is relatively small in the industry, it is more difficult to adjust the process by using the electric eye to judge the high-voltage end point and control the automatic mold adjustment method, which makes it more difficult for the on-site debugging workers to debug, and at the same time, the debugging is unstable. , and the automatic mold adjustment takes a long time.
