[0018] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0019] according to Figure 1 , 2As shown in Figures 3 and 4, this embodiment proposes an aluminum profile extrusion mold that is easy to demold, including a base plate 1, a workbench 3 is installed on the top of the base plate 1, a lower mold 4 is installed above the workbench 3, a demolding mechanism is arranged inside the lower mold 4, a mounting frame 2 is installed above the rear end of the base plate 1, a cylinder 5 is installed on the top of the mounting frame 2, the bottom end of the cylinder 5 extends to the bottom of the mounting frame 2, a mounting plate 6 is installed at the bottom end of the cylinder 5, an upper mold 7 is installed at the bottom end of the mounting plate 6, and fixing mechanisms are arranged on the outer sides of the lower mold 4 and the upper mold 7.

[0020] The demoulding mechanism includes a push plate 8, a mounting cavity 9, a transmission rack 10, a fixed cavity 11 and a transmission structure. A demoulding groove is provided inside the lower mold 4, and a push plate 8 is arranged inside the demoulding groove. The mounting cavity 9 is installed at the top of the bottom plate 1, and a transmission rack 10 is arranged inside the mounting cavity 9. The top of the transmission rack 10 extends to the outside of the mounting cavity 9, and the top of the transmission rack 10 is connected to the bottom end of the push plate 8. A fixed cavity 11 is installed above one side of the mounting cavity 9. The transmission structure includes a servo motor 12, a worm 13, a worm wheel 14 and a transmission gear 15. The servo motor 12 is installed on one side of the fixed cavity 11, and a worm 13 is installed at the bottom end of the fixed cavity 11. The output end of the servo motor 12 is connected to one end of the worm 13. Next, a worm wheel 14 is meshed above the worm 13, and a transmission gear 15 is coaxially installed at the rear end of the worm wheel 14. One side of the transmission gear 15 is meshed with one side of the transmission rack 10. When in use, the servo motor 12 is started to drive the worm 13 to rotate. Since the worm 13 and the worm wheel 14 are meshed with each other, and the worm wheel 14 and the transmission gear 15 are coaxially connected, the transmission gear 15 and the transmission rack 10 are meshed with each other, the transmission gear 15 is used to drive the transmission rack 10 to move, and then the push plate 8 is driven to move. The push plate 8 is used to lift the aluminum profile inside the lower mold 4, and the aluminum profile inside the lower mold 4 can be demoulded, making the aluminum profile inside the lower mold 4 more convenient and efficient when demoulding, thereby greatly improving the convenience of the mold when in use.

[0021] A guide rod 24 is provided through the interior of the mounting frame 2 , and the bottom end of the guide rod 24 is connected to the top end of the mounting plate 6 . When the guide rod 24 is used, the upper mold 7 is more stable when moving.

[0022] The fixing mechanism includes a side plate 16 and a disassembly assembly. The side plate 16 is installed below the mounting plates 6 on both sides of the upper mold 7. A fixing pin is provided through the inside of the side plate 16. The fixing pin can fix the upper mold 7 and can conveniently disassemble the upper mold 7.

[0023] The disassembly assembly includes a vertical plate 17, a threaded groove 18, a threaded rod 19, a rotating wheel 20, a fixed plate 21, a limiting hole 22 and a limiting rod 23. The vertical plate 17 is installed on both sides above the workbench 3. The interior of the vertical plate 17 is penetrated by a threaded groove 18, and the interior of the threaded groove 18 is penetrated by a threaded rod 19. A rotating wheel 20 is installed at one end of the threaded rod 19, and a fixed plate 21 is rotatably installed at the other end of the threaded rod 19. Limiting holes 22 are penetrated on both sides of the vertical plate 17, and a limiting rod 23 is penetrated inside the limiting hole 22. One end of the limiting rod 23 is connected to one end of the fixed plate 21. When in use, the rotating wheel 20 drives the threaded rod 19 to rotate. Since the threaded groove 18 and the threaded rod 19 are threadedly connected, the rotating wheel 20 drives the threaded rod 19 to rotate. The threaded rod 19 moves, and then under the limitation of the limiting hole 22 and the limiting rod 23, the threaded rod 19 drives the fixing plate 21 to move to both sides, so that the lower mold 4 can be taken out from above the workbench 3. At this time, the push plate 8 and the mounting cavity 9 can also be removed by screws, and then the new lower mold 4 and the mounting cavity 9 are placed above the workbench 3 and the bottom plate 1 respectively, and the rotating wheel 20 is rotated in the opposite direction to drive the fixing plate 21 to move, and the new lower mold 4 is fixed by the fixing plate 21, and finally the mounting cavity 9 is fixed by screws to complete the replacement of the lower mold 4. The lower mold 4 and the upper mold 7 can be conveniently disassembled, making it convenient and quick to replace the lower mold 4 and the upper mold 7, so that the mold can process different aluminum profiles, thereby greatly improving the versatility of the mold when used.

[0024] The inner diameter of the limiting hole 22 is larger than the outer diameter of the limiting rod 23, and a sliding structure is formed between the limiting hole 22 and the limiting rod 23. When in use, the limiting hole 22 and the limiting rod 23 cooperate with each other to limit the fixed plate 21 when it moves, so that the fixed plate 21 is more stable when it moves.

[0025] Working principle: First, place the aluminum profile material above the lower mold 4, then start the cylinder 5, and under the guidance of the guide rod 24, drive the mounting plate 6 and the upper mold 7 to move downward, and use the cooperation of the lower mold 4 and the upper mold 7 to extrude the aluminum profile. After the molding is completed, start the cylinder 5 to drive the upper mold 7 to move upward, and then start the servo motor 12 to drive the worm 13 to rotate. Since the worm 13 and the worm wheel 14 are meshed with each other, and the worm wheel 14 and the transmission gear 15 are coaxially connected, and the transmission gear 15 and the transmission rack 10 are meshed with each other, the transmission gear 15 is used to drive the transmission rack 10 to move, and then the push plate 8 is driven to move, and the aluminum profile inside the lower mold 4 is lifted up by the push plate 8. When it is necessary to replace the lower mold 4 and the upper mold 7, the fixed parts on both sides of the side plate 16 are moved. The fixing pin is taken out, and the upper mold 7 can be removed at this time. Then, the fixing pin is used to fix the new upper mold 7, and then the rotating wheel 20 is turned to drive the threaded rod 19 to rotate. Since the threaded groove 18 and the threaded rod 19 are threadedly connected, the threaded rod 19 is driven to move, and then under the limitation of the limiting hole 22 and the limiting rod 23, the threaded rod 19 is used to drive the fixing plate 21 to move to both sides, and the lower mold 4 can be taken out from above the workbench 3. At this time, the push plate 8 and the mounting cavity 9 can also be removed by screws, and then the new lower mold 4 and the mounting cavity 9 are placed above the workbench 3 and the bottom plate 1 respectively, and the rotating wheel 20 is rotated in the opposite direction to drive the fixing plate 21 to move, and the new lower mold 4 is fixed by the fixing plate 21. Finally, the mounting cavity 9 is fixed by screws to complete the replacement of the lower mold 4 and the upper mold 7.
