[0031] A specific application of this embodiment is as follows: In use, align the two fixed cylinders 212 on the lower mold 211 with the two bidirectional threaded rods 214 and insert them into the fixed cylinders 212. Then, turn the handle 217 counterclockwise. The handle 217 drives the rotating shaft 215 to rotate. At this time, the rotating shaft 215 drives the two bidirectional threaded rods 214 to rotate clockwise through the gear 216, thereby driving the two fixed rings 218 to move closer to each other. At this time, the two fixed rings 218 drive the small hinge rod 2110 to rotate on the small hinge block 2112 through the small hinge block 1 219, thereby lifting the fixed plate 2111 so that the outer wall of the fixed plate 2111 contacts the inner wall of the fixed cylinder 212, thereby fixing the lower mold 211. By turning the handle 217 clockwise, through the above reverse operation process, the lower mold 211 can be disassembled and replaced. After the lower mold 211 is fixed, place the material on the lower mold 211 and start the hydraulic cylinder 312. The hydraulic cylinder 312 drives the upper mold 313 to move downward, thereby extruding the material on the lower mold 211 to form it. As the upper mold 313 moves downward, it drives the two rectangular plates 314 to move the bidirectional hinge block 315 downward, thereby driving the two large hinge rods 316 and the large hinge block 319 to move. At this time, the buffer plate 317 also moves. When the bottom of the buffer plate 317 touches the top of the worktable 1, the extrusion force is transmitted to the large hinge block 319 through the buffer plate 317, causing the two large hinge blocks 319 to move away from each other under the action of the two large hinge rods 316. At this time, the angle between the two large hinge rods 316 increases, and the two springs 3111 will be compressed, thereby generating elastic force. Under the action of the buffer plate 317 and the springs 3111, the downward pressure generated by the hydraulic cylinder 312 is reduced. When the hydraulic cylinder 312 drives the upper mold 313 to move upward, it is reset under the action of the elastic force of the two springs 3111.
