The working principle is as follows:

when the die of the hydraulic press needs to be replaced, the turnover mechanism is started;

the turnover mechanism is implemented:

the first step is as follows: starting a lifting motor 9 through a controller, driving a driving plate 11 to slide on the outer side of a lifting screw 10 in a manner that the lifting motor 9 drives the lifting screw 10 to rotate, pushing a damping spring 26 and a push plate 25 to ascend through the driving plate 11, and pushing a replaceable mold 12 to ascend;

the second step: when the replaceable die 12 is pushed into the lifting port 28 by the push plate 25, the clamping seat 7 can be inserted into the clamping groove 14, the inclined surface of the clamping seat 7 can abut against the inclined surface of the fixed rod 16 and push the fixed rod 16 to rotate in the connecting seat 15, the clamping groove 14 extrudes the pushing spring 17 when rotating, so that the pushing spring 17 stores elastic potential energy, when the top of the clamping seat 7 abuts against the bottom of the fixed rod 16, because the clamping seat 7 does not push the fixed rod 16 any more, the pushing spring 17 which stores the elastic potential energy due to extrusion can push the fixed rod 16 to reset, and the fixed rod 16 and the clamping seat 7 are clamped;

the third step: at this moment, the user can start the lifting motor 9 again through the controller, and make the lifting motor 9 drive the lifting screw 10 to rotate reversely, so that the drive plate 11 can slide and descend outside the lifting screw 10, when the drive plate 11 descends to a specified position, the user starts the adjusting motor 4 again, so that the adjusting motor 4 drives the hanging seat 5 to rotate, and reverses the replaceable mold 12 located at the top of the hanging seat 5 to the bottom of the hanging seat 5, and reverses the replaceable mold 12 originally located at the bottom of the hanging seat 5 to the top of the hanging seat 5.

After the replaceable die 12 is replaced, a user can push the clamping mechanism to enable the replaceable die 12 to be quickly separated from clamping;

the implementation steps of the clamping mechanism are as follows:

the first step is as follows: the user starts the lifting motor 9 again and drives the driving plate 11 to rise, at this time, the user pushes the driving plate 21 on the top of another replaceable mold 12, so that the driving plate 21 pushes the pushing rod 20 and presses the return spring 22, and the user pushes the driving plate 21 and the pushing rod 20;

the second step: one end of the push rod 20 can abut against one side of the bottom of the fixed rod 16, and the fixed rod 16 is rotated, so that the fixed rod 16 is separated from the clamping seat 7;

the third step: meanwhile, the user drives the lifting motor 9 to rotate reversely, so that the lifting motor 9 drives the driving plate 11, the sliding rod 24 and the push plate 25 to descend, and the replaced replaceable mold 12 is recovered, and when the user does not apply force to the driving plate 21 any more, the elastic force generated by the extrusion of the reset spring 22 by the driving plate 21 pushes the driving plate 21 and drives the push rod 20 to reset.
