Die-casting machine hydraulic oil circulating filtering and cooling device and method

The invention belongs to the technical field of die-casting machines, and discloses a die-casting machine hydraulic oil circulating filtering and cooling device and method. The die-casting machine hydraulic oil circulating filtering and cooling device comprises an oil tank, a filter, a sucked oil filter and a returning oil filter. A pipeline cooling motor pump used for sucking hydraulic oil into the sucked oil filter from the oil tank and enabling the hydraulic oil to enter is arranged on a pipeline between the sucked oil filter and the returning oil filter. The pipeline between the sucked oil filter and the returning oil filter is further connected with a cooler, a driver and a servo motor pump used for pressing hydraulic oil to the oil tank from the returning oil filter through the pipeline. According to the die-casting machine hydraulic oil circulating filtering and cooling method, the die-casting machine hydraulic oil circulating filtering and cooling device is adopted. According to the die-casting machine hydraulic oil circulating filtering and cooling device and method, circulating filtering and cooling work efficiency is high, and the using quality of hydraulic oil is guaranteed. Meanwhile, the servo motor and the driver are cooled, and therefore the service life of a hydraulic system is prolonged, the production efficiency and stability of the hydraulic system are improved, and reliability is good.
