The lower die 4 is arranged on the top of the base 3. Both sides of the rear side of the top of the operating platform 1 are fixedly connected with support plates 5, a cylinder 6 is fixedly connected to the top of the support plate 5, and a connecting frame 7 is fixedly connected to the bottom of the cylinder 6. The connecting frame 7 facilitates the support of the cylinder 6;

[0023] A connecting plate 8 inserted into the inside of the connecting frame 7, a mounting plate 9 is fixedly connected to the bottom of the connecting plate 8, an upper die 10 is arranged at the bottom of the mounting plate 9, positioning shells 11 are fixedly connected to both sides of the top of the base 3, and a mounting member 12 is arranged inside the positioning shell 11. The mounting member 12 includes a first spring group 1201 and a rotating rod 1202.

[0024] Positioning plates 13 are fixedly connected to both sides of the lower die 4. Inserting plates 14 are fixedly connected to the front and rear sides of the bottom of the positioning plate 13. By inserting the positioning plate 13 and the inserting plate 14 into the inside of the positioning shell 11, the lower die 4 is fixedly installed in cooperation with the mounting member 12. A second spring 15 is fixedly connected to the bottom of the inner cavity of the positioning shell 11, and a pressing plate 16 is fixedly connected to the top of the second spring 15. The second spring 15 and the pressing plate 16 facilitate the auxiliary ejection of the inserting plate 14, and the top of the pressing plate 16 is in movable contact with the inserting plate 14.

[0025] The first spring group 1201 is fixed on both sides of the inner cavity of the positioning shell 11. The rotating rod 1202 is rotatably connected to one side of the inner cavity of the positioning shell 11. On the opposite sides of the two first spring groups 1201, movable plates 1203 are fixedly connected. On the opposite sides of the two movable plates 1203, inserting rods 1204 are fixedly connected. An elliptical wheel 1205 is fixedly connected to the surface of the rotating rod 1202. When the user needs to disassemble and replace the lower mold 4, by rotating the torsion block 1206 to drive the rotating rod 1202, the elliptical wheel 1205 presses against the two movable plates 1203 to drive the inserting rods 1204 to move in opposite directions. At this time, the movable plates 1203 will also drive the sliding blocks 1207 to move in a limited way within the opening of the positioning shell 11, and at the same time, the first spring group 1201 is squeezed and retracted. Then, the inserting rods 1204 are disengaged from the inside of the inserting plate 14, and the lower mold 4 can be removed. One end of the rotating rod 1202 penetrates to the outside of the positioning shell 11 and is fixedly connected with the torsion block 1206. A sliding block 1207 is fixedly connected to the front side of the movable plate 1203. An opening for cooperating with the sliding block 1207 is formed inside the positioning shell 11.

[0026] On both sides of the top of the upper mold 10, first clamping plates 17 are fixedly connected. On both sides of the top of the mounting plate 9, connecting shells 18 are fixedly connected. On one side inside the connecting shell 18, a third spring 19 is fixedly connected. On one side of the third spring 19, a second clamping plate 20 is fixedly connected. On one side of the second clamping plate 20, a pull rod 21 is fixedly connected. One end of the pull rod 21 penetrates to the outside of the connecting shell 18. By pulling the pull rod 21, the second clamping plate 20 squeezes and retracts the third spring 19. Then, the second clamping plate 20 is disengaged from the surface of the first clamping plate 17, thereby completing the disassembly work of the upper mold 10 and improving the disassembly and assembly efficiency. A reinforcing block 22 is fixedly connected to one side of the positioning shell 11. The bottom of the reinforcing block 22 is fixedly connected to the base 3.

[0027] Working principle: First, when the user needs to remove the lower mold 4, rotate the torsion block 1206 to drive the rotating rod 1202, so that the elliptical wheel 1205 presses against the two movable plates 1203 to drive the inserting rods 1204 to move in opposite directions. At this time, the movable plates 1203 will also drive the sliding blocks 1207 to move in a limited way within the opening of the positioning shell 11, and at the same time, the first spring group 1201 is squeezed and retracted. Then, the inserting rods 1204 are disengaged from the inside of the inserting plate 14. At this time, the second spring 15 will drive the pressure plate 16 to reset and assist in bouncing the inserting plate 14, so as to facilitate the removal of the lower mold 4. If it is necessary to replace the upper mold 10, the pull rod 21 can be pulled to make the second clamping plate 20 squeeze and retract the third spring 19. Then, the second clamping plate 20 is disengaged from the surface of the first clamping plate 17, thereby completing the disassembly work of the upper mold 10 and improving the disassembly and assembly efficiency.
