Preferably, the distance from the lower end surface of the ejector 111 to the upper side surface of the upper die tensioning plate 34 is equal to the distance from the lower side surface of the stop structure to the upper side surface of the upper die mounting plate 31.
When the pressing operation is carried out, firstly, the brake pad pasted with the gasket is prevented from being arranged on the lower mould pressing plate 53, then the oil cylinder 2 is started, the piston rod of the oil cylinder 2 extends out to drive the upper mould component 4 to move downwards, and the brake pad pasted with the gasket is pressed. After pressing is completed, the piston rod of the oil cylinder 2 retracts to drive the upper die assembly 4 to move upwards, so that the pressing operation is completed, and at the moment, a certain distance is reserved between the lower end of the ejector rod 111 and the upper die tensioning plate 34.
When the mould needs to be replaced, the piston rod of the control oil cylinder 2 continues to retract, and when the lower end face of the ejector rod 111 abuts against the upper side face of the upper mould tensioning plate 34, the lower side face of the stop structure abuts against the upper side face of the upper mould mounting plate 31. The piston rod of the cylinder 2 continues to retract, and at this time, the upper die tensioning plate 34 presses against the lower end surface of the ejector rod 111 and keeps the absolute position unchanged under the action of the ejector rod 111. Because the piston rod of the oil cylinder 2 is still retracted, the upper die mounting plate 31 is driven to move upwards through the connecting plate, and the upper die pressing spring 38 is compressed, so that the upper die pressing plate 43 is disengaged from the upper die pressing plate 371. Meanwhile, in the process that the oil cylinder 2 drives the upper die mounting plate 31 to move upwards, because the lower side surface of the stopping structure is abutted against the upper side surface of the upper die mounting plate 31, the lower die tensioning plate 61 can move upwards under the action of the pull rod 64, and then the lower die pressing spring 63 is compressed, and the lower die pressing plate 621 is separated from the lower die pressing plate 53. At this time, the upper platen 43 and the upper platen 371, and the lower platen 53 and the lower platen 621 are in a disengaged state, and the upper platen 43 and the lower platen 53 are directly replaced.

Further, as shown in fig. 3, the upper die tensioning plate 34 is provided with a notch for avoiding the pull rod 64 and the stop nut 641.
Further, in order to ensure uniform stress, as shown in fig. 6, 7 and 9, the connecting plates sequentially include a first connecting plate 32 and a second connecting plate 33 from top to bottom, the first connecting plate 32 is fixedly connected with the second connecting plate 33 through bolts, and the first connecting plate 32 is fixedly connected with a piston rod of the oil cylinder 2.

As a specific implementation manner, 8 guide bolts 35 are disposed between the second connecting plate 33 and the upper die mounting plate 31 in this embodiment, and eight guide bolts 35 are arranged in a matrix of four rows and two columns.
Further, as shown in fig. 9, the hole of the second connecting plate 33 for accommodating the guide bolt 35 is a counter bore, and a distance M between an upper end surface of the guide bolt 35 and an upper end surface of the second connecting plate 33 is greater than a maximum compression amount of the disc spring 36. In this way, the guide bolt 35 can be arranged below the first connecting plate 32, which makes the overall design more compact.
Further, since the second connecting plate 33 moves downward relative to the guide bolt 35 during the pressing process, the guide bolt 35 is in a non-tensioned state, and the problem of loosening and the like is likely to occur. For this, as shown in fig. 10, a backing plate 351 is disposed on a lower end surface of the guide bolt 35, the backing plate 351 is fixedly connected to the guide bolt 35 by a first locking screw 352, and a groove for receiving the backing plate 351 is disposed on a lower side surface of the second connecting plate 33. The first locking screw 352 is rotated in the opposite direction to the guide bolt 35.
