In order to reduce the pressing time and improve the working efficiency, in an embodiment of the present invention, the upper and lower die quick-change structure includes: a first sensor 901, a second sensor 903, a third sensor 904, and a sensing rod 902; the first sensor 901 is fixedly arranged on the front side of the fixed seat 103; the sensing rod 902 is installed on the upper positioning plate 604, the upper end of the sensing rod 902 passes through a through hole of the sensing rod 902 arranged on the fixing base 103 and then extends out to the upper side of the fixing base 103, and a signal receiver capable of receiving the signal of the first sensor 901 during the moving process is arranged on the sensing rod 902. The second sensor 903 is fixedly mounted on the fixed seat 103 right below the first sensor 901; the third sensor 904 is fixedly mounted on the fixing base 103 right below the second sensor 903, the signal receiver can move between the first sensor 901 and the second sensor 903 and can correspondingly receive the transmission signals of the second sensor 903 and the third sensor 904, and the signal receiver is electrically connected to the controller. When the upper die and the lower die need to be replaced, the piston rod of the hydraulic cylinder is controlled to retract until the signal receiver on the sensing rod moves upwards to the position of the first sensor, the piston rod of the hydraulic cylinder continues to retract until the limiting rod 606 is in hard contact with the limiting stop part (namely the upper pressure spring is enough to compress the piston spindle of the hydraulic cylinder and cannot continue to retract), at the moment, the upper pressing sheet and the lower pressing sheet are respectively loosened from the upper die and the lower die, and the upper die and the lower die can be directly taken down for replacement. After a new mold is replaced, the piston rod is controlled to extend out, and when the signal receiver moves downwards and receives a signal of the first sensor 901, the mold reaches a compaction state. When the signal receiver on the sensing rod 902 receives the signal of the first sensor 901 during the brake pad pressing process, the controller controls the piston main shaft of the hydraulic cylinder to extend rapidly, the upper die moves downwards at a higher speed, when the signal receiver on the sensing rod 902 receives the signal of the second sensor 903 (at the moment, the piston main shaft is close to the surface of the brake pad), the controller controls the piston main shaft of the hydraulic cylinder to extend at a slower speed, and the upper die presses the brake pad at a slower speed; when the pressure sensor reaches a set value, the controller controls the hydraulic cylinder to keep acting to perform pressure maintaining, and the piston spindle retracts into the upper die and is lifted after the pressure maintaining is carried out for a set time. If the pressure sensor is abnormal, if the controller does not receive the signal of the pressure sensor, and the signal receiver receives a third sensor signal 904 (as a lower limit sensor), the equipment is stopped and alarmed. The first sensor, the second sensor and the third sensor in the invention can be suitable sensor types capable of realizing induction limiting, and in one embodiment of the invention, the first sensor, the second sensor and the third sensor are all proximity switches. The brake pad pressing device disclosed by the invention can be used for simultaneously realizing the quick pressing and releasing of the upper die and the lower die by utilizing one hydraulic oil cylinder, and can automatically realize the actions of die replacement, high-speed airborne landing, low-speed pressing, abnormal alarming and the like of the hydraulic oil cylinder under the coordination of the first sensor, the second sensor and the third sensor, so that the working efficiency is improved, the automation degree is higher, the pressed brake pad has better quality consistency and more stable performance.
