[0025] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process. The specific work is as follows.

[0026] With the support of the base 1, the forging material can be put into the lower die body 26, and then the hydraulic cylinder 22 on the gantry 21 is extended and driven, and the upper die body 23 is driven to descend through the limit of the slide bar 24 to fit with the lower die body 26 supported by the die base to form the forging; When the upper mold body 23 moves downward, the transfer arm 51 in the force-applying structure 5 is driven downward, and at the same time, the motor 53 on the driving plate 52 drives the force-applying rod 54 to rotate to be relatively parallel to the other end of the transfer arm 51. When the upper mold body 23 and the lower mold body 26 are in contact, the force-applying rod 54 passes through the force-bearing roller 45 in the pushing structure 4, and is driven by the motor 53 to rotate to be relatively vertical to the other end of the transfer arm 51. When the hydraulic cylinder 22 is reset after molding and drives the upper mold body 23 to rise, the inclined wall surface at the other end of the force-applying rod 54 contacts the force-bearing roller 45. As the force-applying rod 54 rises, the force-bearing roller 45 contacts and rotates with the force-applying rod 54 and moves to the right to be stressed, thereby driving the push arm 42 to move to the right on the push seat 41, compressing the spring 43 through the baffle 8, and connecting with the push seat 34 in the jacking structure 3 with the help of the transfer rod 44, driving the push seat 34 to move to the right in the limit seat 31 through the moving groove 7. Since the push seat 34 is connected to the lifting seat 32 through the inclined support arm 35, when the push seat 34 moves to the right, the lifting seat 32 cannot move left or right due to the limit of the lifting slot 6, and then the support arm 35 is turned by force, and the lifting seat 32 is lifted and moved by the pulley 33, and then the lifting unit 36 ​​is driven to rise, that is, the lifting rod 363 is lifted and passes through the top hole of the lower mold body 26 to demould the workpiece; When the force-applying rod 54 is separated from the force-bearing roller 45, the pushing arm 42, the pushing seat 34 and the lifting seat 32 are reset by the force of the spring 43; Since the flip arm 362 in the lifting unit 36 ​​can be flipped open on the top seat 361, the position of the top rod 363 on the flip arm 362 and the top seat 361 can be adjusted to fit the top hole positions of the lower mold body 26 or small mold body of different sizes according to the actual mold groove, thereby improving the practicability of demoulding.
