[0022] See also Figures 1 to 4 The utility model provides a technical solution: a large-scale long core-pulling mold opening double-cylinder back-pulling structure, including: a bottom plate 1 and two fixed plates 2, the two fixed plates 2 are fixedly installed at the two ends of the upper surface of the bottom plate 1, a first slide groove 4 is opened in the middle part of the upper surface of the bottom plate 1, and symmetrical second slide grooves 12 are opened on both sides of the first slide groove 4, a second motor 19 is fixedly installed on one side of one of the fixed plates 2, and an electric push rod 13 is fixedly installed on one side of the other fixed plate 2, a threaded rod 3 is rotatably connected between the two fixed plates 2, the output end of the second motor 19 passes through the fixed plate 2 and is fixedly connected to one end of the threaded rod 3, the output end of the second motor 19 passes through the fixed plate 2 and is rotatably connected thereto, a first slider 8 is threadedly connected to the threaded rod 3, the rotation of the second motor 19 will drive the rotation of the threaded rod 3, the rotation of the threaded rod 3 will drive the first slider 8 to slide in the first slide groove 4, the first slider 8 is slidably connected to the first slide groove 4, and one side of the first slider 8 A first motor 7 is fixedly installed, and a core pulling cylinder 9 is fixedly connected to the output end of the first motor 7. The first motor 7 can drive the core pulling cylinder 9 to rotate. The core pulling cylinder 9 rotates and approaches the object, so the object can be core-pulled and cut. A telescopic rod 10 is arranged below the core pulling cylinder 9, and the telescopic rod 10 passes through the middle of the first slider 8 and is slidably connected thereto. One end of the telescopic rod 10 is fixedly connected to a first waste box 11, and a first spring 5 is fixedly connected between the first waste box 11 and the first slider 8. The telescopic rod 10 passes through the first spring 5 and is slidably connected thereto. During the rotation of the second motor 19, the first waste box 11 will move toward the cutting object until the cutting box is fitted with the object and the box will no longer move. At this time, the first spring 5 is compressed, and the telescopic rod 10 slides in the opposite direction of the first slider 8. A clamping mechanism 6 is arranged at the output end of the electric push rod 13, and the clamping mechanism 6 is used to clamp the module to ensure the stability of the module during the core pulling process.
[0023] Specifically, the clamping mechanism 6 includes a first clamping plate 16, a second clamping plate 18 and a clamping platform 17. One side of the clamping platform 17 is fixedly connected to the output end of the electric push rod 13. The extension and retraction of the electric push rod 13 directly controls the sliding of the clamping platform 17. The first clamping plate 16 and the second clamping plate 18 are respectively arranged on both sides of the clamping platform 17. The two sides of the clamping platform 17 are fixedly installed with sliding rods 14. The sliding rods 14 pass through the first clamping plate 16 and the second clamping plate 18 respectively and are slidably connected thereto. The first clamping plate 16 is threadedly connected with a screw 15. The distance between the first clamping plate 16 and the clamping platform 17 can be changed by rotating the screw 15, thereby indirectly changing the core pulling. The screw 15 passes through the first clamping plate 16 and is threadedly connected to one side of the clamping platform 17. A first cylindrical groove 25 is provided on the other side of the clamping platform 17. A second telescopic column 30 is slidably connected in the first cylindrical groove 25. One end of the second telescopic column 30 is fixedly connected to the second clamping plate 18. Under normal circumstances, the second clamping plate 18 will be firmly pressed against the clamping platform 17, and the second spring 27 will be in an extended state at this time. It is because of the existence of the second spring 27 that force is required to pull the second clamping plate 18 outward. Similarly, the clamping is more powerful when clamping an object. The other end of the second telescopic column 30 is fixedly connected to the second spring 27.
[0024] Secondly, a symmetrical second slider 23 is fixedly connected to the bottom wall of the clamping platform 17, and the two second sliders 23 are respectively slidably connected to the second slide groove 12. When the output end of the electric push rod 13 moves, the clamping platform 17 and the second slider 23 are driven to slide along the second slide groove 12, so that after the object to be pulled out is cut by the core pulling tube 9, the movement of the electric push rod 13 is used to pull out the cut object to achieve reverse extraction.
[0025] In addition, a rectangular groove 31 and a third slide groove 21 are provided on the upper surface of the clamping platform 17, and a second waste box 32 is arranged in the rectangular groove 31. When the clamped mold is large, it may exceed the carrier. At this time, the first waste box 11 will not contact the third slide groove 21. When the clamped mold is small, the first waste box 11 will slide in the third slide groove 21 until it hits an object. As the second motor 19 continues to rotate, the particles and waste in the cutting process will fall from the entrance of the core pulling and fall into the first waste box 11. When the core pulling is completed, when the core pulling tube 9 passes through the mold, the internal waste will fall into the second waste box 32.
[0026] In addition, a second cylindrical groove 26 is opened below the first cylindrical groove 25, and a first telescopic column 29 is slidably connected in the second cylindrical groove 26. A third spring 28 is fixedly connected between the first telescopic column 29 and the second cylindrical groove 26. After the mold is taken away, the second clamping plate 18 will move quickly toward the clamping platform 17 due to the existence of the second spring 27. The setting of the third spring 28 and the first telescopic column 29 plays a certain buffering role, which effectively ensures that the second clamping plate 18 and the clamping platform 17 will not collide violently.
[0027] Finally, a plurality of triangular teeth 24 are disposed on one side of the first clamping plate 16 and the second clamping plate 18. The arrangement of the triangular teeth 24 makes it difficult for the mold clamped by the clamping mold to move.
[0028] When the device is working, the mold that needs to be cored is first clamped on the clamping mechanism 6, and then the first motor 7 and the second motor 19 are started. The first motor 7 will drive the core pulling cylinder 9 to rotate, and the second motor 19 will drive the entire new core pulling device to move toward the mold, so that the core pulling cylinder 9 can cut the mold core. During this process, a first waste box 11 will first contact the mold, and then will be under pressure and pressed on the mold. At this time, as the first motor 7 and the second motor 19 continue to run, the core pulling cylinder 9 will be above the first waste box 11 and extend into the mold for core pulling. The waste generated at this time will fall from the entrance into the first waste box 11. When the core pulling cylinder 9 penetrates the mold, some waste will fall into the second waste box 32 at the penetration position. In this way, the waste generated in the core pulling process is caught, which effectively ensures that the waste will not fall on the bottom plate 1, avoiding cleaning of the bottom plate 1.
[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
