The working principle is as follows:

in operation, when raw material is put into the lower die 9, the first hydraulic rod 2 moves downward, the first hydraulic rod 2 drives the transverse plate 3 to move downward, the transverse plate 3 drives the supporting block 4 at the lower end to move downward, the supporting block 4 drives the upper die 6 to move downward, until the upper die 6 moves to the first groove 7, because the first protrusion 1202 makes the first supporting rod 1200 rotatably connected to the circle 1208, when the material descends, the circle 1208 does not rotate, and presses the material, at this time, the first hydraulic rod 2 moves upward, drives the transverse plate 3 to move upward and simultaneously drives the first supporting rod 1200 fixedly connected on the left side to move upward inside the second circular hole 1207, the first supporting rod 1200 moves upward and drives the first rotating wheels 1201 to move upward, at this time, the first rotating wheels 1201 sequentially push the first protrusion 1202 to slide, under the action of the stop block 1212, so that the first supporting rod 1208 rotates inside the annular groove 1209, when the circle 1208 rotates, at this time, because the second groove 1210 is designed into an arc shape, the second groove 1210 pushes against the moving wheel 1211 to move inwards, at this time, the moving wheel 1211 drives the T-shaped block 1204 to

after the unhairing is completed, the second hydraulic rod 11 moves upwards at this time, the lower die 9 is driven to move upwards at the same time, the material is ejected, thus the edge of the material is directly cut off, the workload of a person is reduced, the production efficiency is improved, when the second support rod 40 moves downwards, the second rotary block 15 is pushed against, because the number of the second rotary wheel 38 is greater than that of the second rotary block 15, therefore, the second rotating wheel 38 can move the moving block 14 to the rearmost, when the second support rod 40 moves upwards, the moving block 14 can be moved to the foremost part, the moving block 14 drives the first piston 41 to move forwards in the first sleeve 16, at this time, the pressure inside the first sleeve 16 is increased, when the second hydraulic rod 11 drives the lower die 9 to move upwards, the blocking block 19 is separated from the vent hole 18, at this time, gas enters the vent hole 18, so that the pressure at the bottom is ensured to be the same as the pressure of outside air, demoulding is easier, after the second support rod 40 moves out, the moving block 14 is reset due to the action of the second spring 37, demoulding is easier after the pressure is increased, when the transverse plate 3 moves upwards, at this time, the transverse plate 3 drives the two sliding blocks 21 to move inside the corresponding sliding grooves 20, the right slide block 21 moves downwards and drives the threaded rod 22 connected with the threads to rotate, the threaded rod 22 drives the sweeping rod 23 fixedly connected with the bottom to move when rotating, so that the materials can be discharged, the required manpower is reduced, the supporting block 4 is driven to move upwards when the transverse plate 3 moves upwards, the second convex ball 27 is driven to move upwards when the supporting block 4 moves upwards, the second convex ball 27 moves towards the inside of the third groove 25 and extrudes the third spring 26 due to the extrusion of the first convex ball 24, when the supporting block is dislocated with the first convex ball 24, the second convex ball 27 moves outwards under the tension of the third spring 26, the vibration is generated due to collision, the demoulding effect of the top is better, when the sweeping rod 23 pushes the materials to the bearing plate 30, the bearing plate 30 slowly descends due to the increase of gravity, at this moment, when the transverse plate 3 moves downwards, when the rear side of the loading plate 30 pushes up the two limit blocks 31, the two first telescopic rods 28 at the rear end contract, so that the whole loading plate 30 is inclined, the material is unloaded, when the transverse plate 3 moves upwards, the loading plate 30 resets, so that the damage to the material during unloading can be reduced, when the transverse plate 3 moves downwards, the transverse plate 3 drives the second telescopic rods 32 to move downwards, when the transverse plate 3 moves to a proper position, the transverse plate pushes against the second piston 34 to move downwards, the gas in the second sleeve 33 is compressed, the gas in the second sleeve 33 is sprayed out from the spray head 36 through the second gas pipe 35, so that the sundries on the workbench 5 can be removed, and the damage to the material is avoided.
