Abstract

The invention discloses a mold protection method, system and readable storage medium. The method includes: acquiring the reference value of the motor load rate in the preset range and the instantaneous value of the motor load rate in the low-voltage range of the mold clamping, Wherein the preset interval is located in the low-voltage interval; judging whether the deviation value between the instantaneous value of the motor load rate and the reference value of the motor load rate is greater than a preset deviation threshold, if the deviation value is greater than the set If the preset deviation threshold is exceeded, the clamping of the mold is stopped. In the present invention, the load rate of the motor within the preset interval in the previous mold clamping process is formed as a reference value as a basis for detecting foreign objects, which is beneficial to improve the accuracy of detection; moreover, both the reference value and the instantaneous value are filtered by the current After conversion, it avoids the interference of interference signals, further improves the accuracy of detection, and is beneficial to accurately start mold protection.

Description

technical field [0001] The invention relates to the technical field of electric control, in particular to a mold protection method, system and readable storage medium. Background technique [0002] The all-electric injection molding machine is a kind of plastic injection molding equipment. It is different from the hydraulic transmission mode of the pump and the hydraulic cylinder used in the hydraulic injection molding machine. It adopts the mechanical transmission mode of the servo system and the lead screw. with higher precision. The mold clamping process of an all-electric injection molding machine is usually divided into three stages: fast mold clamping, low pressure mold protection and high pressure mold clamping. The high-sensitivity foreign object detection capability in the low-pressure mold protection zone can prevent problems such as machine unbalanced load and mold surface damage, effectively protect the safety of the machine and mold, and prolong the service lif...
