Specific implementation manners

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0026] Referring to Figures 1-7 , an aluminum extrusion die that is convenient for disassembly and assembly includes a lower connection seat 1, an upper connection seat 2, and a frame 17. A lower die 4 is provided at the top of the lower connection seat 1, and an upper die 3 is provided at the bottom of the upper connection seat 2. Inclined plane blocks 5 are fixed to the top of the upper die 3 and the bottom of the lower die 4 by bolts. Card slots 6 are provided on both sides of the inclined plane block 5. A plurality of side elastic telescopic rods 7 are fixed to the inner walls on both sides of the lower connection seat 1 and the upper connection seat 2 by bolts. The other ends of the plurality of side elastic telescopic rods 7 are jointly fixed to a card block 8 by bolts. The card block 8 is clamped with the card slot 6. Under the elastic action of the side elastic telescopic rod 7, the card block 8 is clamped with the card slot 6, thereby fixing the upper die 3 and the lower die 4. A bidirectional threaded rod 9 is rotatably inserted between the two sides of the lower connection seat 1 and the upper connection seat 2. Sliding plates 11 are threadedly sleeved at both ends of the bidirectional threaded rod 9. The sliding plate 11 contacts the card block 8. Two guide rods 10 are welded between the inner walls on both sides of the lower connection seat 1 and the upper connection seat 2. The sliding plate 11 is slidably sleeved with the guide rod 10. By screwing the bidirectional threaded rod 9, the sliding plate 11 is driven to move outward along the guide rod 10, thereby driving the card block 8 to move outward, and further enabling the card block 8 to be separated from the card slot 6, thereby facilitating the disassembly of the upper die 3 and the lower die 4.

[0027] A plurality of ball-headed rods 12 are welded to the inner wall of the bottom of the lower connecting seat 1 and the inner wall of the top of the upper connecting seat 2. A plurality of positioning holes 13 are provided on the inclined plane block 5. The ball-headed rods 12 are inserted into the positioning holes 13, so as to facilitate the positioning and installation of the upper die 3 and the lower die 4. A plurality of lower elastic telescopic rods 14 are fixed to the inner wall of the bottom of the lower connecting seat 1 and the inner wall of the top of the upper connecting seat 2 by bolts. One end of the lower elastic telescopic rod 14 passes through the lower connecting seat 1 and the upper connecting seat 2 and contacts the inclined plane block 5. Under the elastic action of the lower elastic telescopic rod 14, the inclined plane block 5 is elastically pushed outwards, so that the upper die 3 and the lower die 4 are separated from the upper connecting seat 2 and the lower connecting seat 1, and then it is convenient to take down the upper die 3 and the lower die 4. An outer rubber pad 15 is bonded to the inner wall of the clamping groove 6, and an inner rubber pad 16 is bonded to the outer wall of the top of the lower connecting seat 1 and the outer wall of the bottom of the upper connecting seat 2. The lower connecting seat 1 is fixed to the inner wall of the bottom of the frame 17 by bolts. A hydraulic cylinder 18 is fixed to the outer wall of the top of the frame 17 by bolts. One end of the hydraulic rod of the hydraulic cylinder 18 is fixedly connected to the upper connecting seat 2. Driven by the hydraulic cylinder 18, the upper connecting seat 2 moves downwards, so as to drive the upper die 3 to move towards the lower die 4, and then the upper die 3 contacts the aluminum material, and thus the aluminum material is extruded into shape. A plurality of sliding rods 19 are welded to the top of the upper connecting seat 2. The movement of the upper connecting seat 2 is guided by the sliding rods 19, so as to improve the stability of aluminum material extrusion. The sliding rods 19 are slidably inserted into the top of the frame 17.

[0028] The working principle of this embodiment: When in use, first, place the aluminum material on the lower die 4. Then, driven by the hydraulic cylinder 18 and guided by the sliding rods 19, the upper connecting seat 2 moves downwards, so as to drive the upper die 3 to move towards the lower die 4, and then the upper die 3 contacts the aluminum material, and thus the aluminum material is extruded into shape. When it is necessary to replace the upper die 3 and the lower die 4, turn the bidirectional threaded rod 9 to drive the sliding plate 11 to move outwards along the guide rod 10, so as to drive the clamping block 8 to move outwards, and then the clamping block 8 is separated from the clamping groove 6. Then, under the elastic action of the lower elastic telescopic rod 14, the inclined plane block 5 is elastically pushed outwards, so that the upper die 3 and the lower die 4 are separated from the upper connecting seat 2 and the lower connecting seat 1. Then, respectively clamp the new upper die 3 and the lower die 4 on the upper connecting seat 2 and the lower connecting seat 1. Then, turn the bidirectional threaded rod 9 in the reverse direction to make the two sliding plates 11 gather towards the middle, and then under the elastic action of the side elastic telescopic rod 7, the clamping block 8 is clamped with the clamping groove 6, so as to fix the upper die 3 and the lower die 4.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and all should be covered within the protection scope of the present invention.
