When the worker eliminates the abnormal problem, the injection molding machine is restarted, a lubricating starting instruction is output, the lubricating pump is enabled to perform lubricating operation, and when the lubrication is normal, the abnormal prompt information can be automatically removed.

In the full-automatic production process of the injection molding machine, if abnormal prompt information appears, the full-automatic production can be carried out after related alarm needs to be solved, otherwise, the full-automatic production of the injection molding machine cannot be carried out. The stability of the injection molding machine in the operation process is ensured, and the stability and the high efficiency of equipment during production can be ensured only by properly lubricating all parts.

Specifically, after the oil way distributors of all the parts of the injection molding machine receive the pressure relief instruction, the pressure relief action is executed, and the lubricating grease quantity matched with the parts in the metering parts of all the parts of the injection molding machine is conveyed to all the parts to lubricate all the parts. If the lubricating pressure value is not reduced to the initial pressure value within the preset pressure relief time, the fact that the lubricating oil distributors do not convey the lubricating oil quantity matched with the lubricating oil quantity in the metering parts of all the components of the injection molding machine to all the components is indicated, the pressure relief action is not completed within the preset pressure relief time, the fact that the lubricating pipelines are blocked or the pressure sensors are damaged is indicated, and pressure relief abnormity prompt information is output to remind a worker to solve the problem that pressure is not relieved.
