[0024] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a motion core mold propulsion mechanism for fiberglass grating production.
[0025] like Figure 1-5 As shown, this utility model discloses a motion mandrel propulsion mechanism for fiberglass grating production, comprising a grating body 1, a mandrel body 2 disposed at the bottom of the surface of the grating body 1, a hydraulic propulsion mechanism 3 welded to the bottom of the mandrel body 2, a first telescopic rod 5 installed at one end of the hydraulic propulsion mechanism 3, a second telescopic rod 6 sleeved inside the first telescopic rod 5, a fixing plate 7 welded to the surface of the first telescopic rod 5, a fixing ring 9 installed on the surface of the second telescopic rod 6, a fixing plate 10 fixedly connected to the surface of the fixing ring 9, an internally threaded sleeve 11 welded inside the fixing plate 10, a limiting rod 12 sleeved inside the internally threaded sleeve 11, and an external thread on the surface of the limiting rod 12. When the limiting rod 12 is installed inside the internal threaded sleeve 11, the external thread on the surface of the limiting rod 12 can be used to fix the limiting rod 12 inside the internal threaded sleeve 11, ensuring the stability of the limiting rod 12 during use. The top of the fixing plate 7 is welded with a sleeve 8, through which the limiting rod 12 passes. By installing the limiting rod 12 and the sleeve 8, the limiting rod 12 can provide a limiting effect between the first telescopic rod 5 and the second telescopic rod 6 during the use of the device, so that the first telescopic rod 5 and the second telescopic rod 6 will not rotate or deviate at an angle, ensuring the stability of the device during use.
[0026] The second telescopic rod 6 has a support ring 14 welded to its surface, and an external threaded rod 15 welded to the top of the support ring 14. The external threaded rod 15 passes through the fixing ring 9, and a nut 16 is fitted onto the surface of the external threaded rod 15. One end of the nut 16 is attached to the top of the fixing ring 9, and the bottom of the fixing ring 9 is attached to the top of the support ring 14. By installing the external threaded rod 15, when it is necessary to install the fixing ring 9, the external threaded rod 15 can be directly passed through the fixing ring 9 until the bottom of the fixing ring 9 is attached to the top of the support ring 14. Then, the nut 16 is fitted onto the surface of the external threaded rod 15 until one end of the nut 16 is attached to the bottom of the fixing ring 9. At this time, the fixing ring 9 can be fixed, ensuring the stability of the fixing ring 9 during use.
[0027] The bottom of the hydraulic propulsion mechanism 3 is welded with a mounting plate 4. A groove 18 is formed on the top of the mounting plate 4. A sliding groove 19 is formed inside the groove 18. A sliding rod 20 is sleeved inside the sliding groove 19. A mounting piece 17 is welded to one end of the sliding rod 20. The mounting pieces 17 are located inside the groove 18 and are symmetrically distributed. After the mounting plate 4 is installed, the mounting pieces 17 can be moved through the sliding groove 19 and the sliding rod 20 until the mounting pieces 17 protrude from the mounting plate 4. Then, the mounting area of the mounting plate 4 can be expanded by the mounting pieces 17. The mounting pieces 17 can then be used again to install the device, thereby further improving the stability of the device after installation.
[0028] The mounting plate 4 has a slot 21 at the bottom, and an anti-slip pad 22 is glued inside the slot 21. By installing the anti-slip pad 22, the friction between the mounting plate 4 and the installation position can be increased, thereby improving the stability of the device after installation and improving the stability effect during use.
[0029] The limiting rod 12 is arranged in a ring shape. A rotating plate 13 is welded to one end of the limiting rod 12. By installing the rotating plate 13, when it is necessary to rotate the limiting rod 12, the rotating plate 13 can be used as the force point, and the limiting rod 12 can be directly driven to rotate through the rotating plate 13, which is very convenient to use.
[0030] The sliding grooves 19 and the sliding rods 20 are symmetrically distributed. The distribution of the sliding grooves 19 and the sliding rods 20 can improve the stability of the mounting plate 17 when it moves, making it very convenient to use.
[0031] The working principle of the motion core mold propulsion mechanism for FRP grating production is as follows: First, the mounting plate 4 is installed in a suitable position. After installation, the mounting piece 17 can be moved via the sliding groove 19 and sliding rod 20 until it protrudes from the mounting plate 4. This expands the installation area of the mounting plate 4. The mounting piece 17 can then be used again to install the device, further improving its stability after installation. Next, the fixing ring 9 is installed. When installing the fixing ring 9, the external threaded rod 15 is directly inserted through it until the bottom of the fixing ring 9 is against the top of the support ring 14. Then, a nut 16 is fitted onto the surface of the external threaded rod 15 until one end of the nut 16 is against the bottom of the fixing ring 9. This provides a secure installation for the fixing ring 9. The device can then be used. When using the device, a first telescopic rod 5 is installed at one end of the hydraulic propulsion mechanism 3, and a second telescopic rod 6 is sleeved inside the first telescopic rod 5. A fixing plate 7 is welded to the surface of the first telescopic rod 5, and a fixing ring 9 is installed on the surface of the second telescopic rod 6. A fixing plate 10 is fixedly connected to the surface of the fixing ring 9, and an internal threaded sleeve 11 is welded inside the fixing plate 10. A limiting rod 12 is sleeved inside the internal threaded sleeve 11. At this time, an external thread is opened on the surface of the limiting rod 12, and a sleeve 8 is welded to the top of the fixing plate 7. The limiting rod 12 passes through the sleeve 8. During the use of the device, the limiting rod 12 can be used to provide a limiting effect between the first telescopic rod 5 and the second telescopic rod 6, so that the first telescopic rod 5 and the second telescopic rod 6 will not rotate or deviate at an angle, thus ensuring the stability of the device during use.
