[0027] Based on this, in order to improve the technical problem in the related art that the entire lower mold and the fixing seat need to be replaced when producing insulators of different lengths, the embodiments of the present application provide the following solution.

[0028] The following combination Figures 1-10 The present invention is described in further detail.

[0029] This embodiment discloses a composite insulator production mold with a three-module structure that can be quickly interchanged and adjusted. The composite insulator production mold with a three-module structure that can be quickly interchanged and adjusted includes a mold frame 1, a mold head 2, a module 3, a mold core 4, and a fixing mechanism.

[0030] The mold frame 1 is provided with a mold groove 11, the cross section of which is a right-angled trapezoid. The die head 2 and the module 3 are both arranged inside the mold groove 11. The die head 2 and the module 3 are both provided with a mold cavity 21. The die head 2 is also provided with a mold opening 22. Connecting posts 41 are fixedly provided at both ends of the mold core 4. The mold core 4 is provided inside the mold cavity 21, and the connecting posts 41 are provided inside the mold opening 22. The outer peripheral surface of the connecting posts 41 abuts against the die head 2.

[0031] The mold frame 1, the die head 2, and the die block 3 are each provided with a plurality of bayonet slots 12. Bayonet pins 13 are slidably connected to the bayonet slots 12. A fixing plate 14 is fixedly provided at one end of the bayonet pin 13. Connecting magnets 141 are fixedly provided on the fixing plate 14 and the mold frame 1. The fixing plate 14 and the mold frame 1 are fixedly connected via the connecting magnets 141. A pull ring 142 is fixedly provided at the end of the fixing plate 14 away from the bayonet pins 13.

[0032] The fixing mechanism includes a pressing plate 51 and an adjusting assembly 52. ​​A first slide groove 15 is provided on the mold frame 1. Sliding plates 53 are fixedly provided on both sides of the pressing plate 51. The sliding plates 53 are slidably connected to the inside of the first slide groove 15.

[0033] The adjustment component 52 includes a threaded rod 521 and a limiting ring 522. A limiting groove 511 is opened inside the pressure plate 51. The limiting ring 522 is rotatably connected inside the limiting groove 511. The threaded rod 521 passes through the mold frame 1 and is threadedly connected to the mold frame 1. One end of the threaded rod 521 is passed through the pressure plate 51 and is fixedly connected to the limiting ring 522. The other end of the threaded rod 521 is fixedly provided with a handle 5211.

[0034] From the above, it can be seen that the embodiment of the present application provides a quick interchange and adjustment structure module 3 composite insulator production mold. The staff can pull the fixing plate 14 through the pull ring 142 to separate the connecting magnets 141 from each other, and then continue to pull the fixing plate 14. The fixing plate 14 pulls the latch 13 from the inside of the latch groove 12 to slide outside the mold frame 1. After the latch 13 slides to a certain distance, the staff can determine the number of modules 3 according to the length of the insulator to be produced, and then place the two die heads 2 and each module 3 into the mold groove 11 and arrange the modules 3 between the two die heads 2. Since one side of the mold groove 11 is a slope, the staff does not need to place the die head 2 and the module 3. It is necessary to ensure that the die head 2 and the module 3 are completely aligned with the die groove 11, which makes it more convenient for the staff to install the die head 2 and the module 3; then the threaded rod 521 is twisted by the handle 5211, and the mold frame 1 pushes the threaded rod 521 and the limiting ring 522 toward the die head 2 through the thread. At the same time, the part of the threaded rod 521 located inside the pressure plate 51 drives the limiting ring 522 to rotate inside the limiting groove 511, and the limiting ring 522 pushes the pressure plate 51 toward the die head 2, and the pressure plate 51 will drive the sliding plate 53 to slide inside the first slide groove 15. When the pressure plate 51 contacts the die head 2, the staff can continue to twist the handle 5211 until the pressure plate 51 presses the die head 2, and the die head 2 presses each module 3 with And the die head 2 at the other end is pressed tightly into the mold groove 11, and then the pull ring 142 is pushed to insert each bayonet 13 into the bayonet groove 12 on the module 3 and the die head 2 until the connecting magnets 141 contact each other. At this time, the installation and fixation of the die head 2 and then the module 3 are completed, which can prevent the module 3 or the die head 2 from moving during the production process and causing the mold to produce defective products; then the connecting columns 41 at both ends of the mold core 4 are placed into the die opening 22 on the die head 2, so that the mold core 4 is located inside the cavity 21, and then the upper mold is controlled to be pressed onto the mold, the die head 2 on the upper mold is fitted with the die head 2, the module 3 is fitted with the module 3, the die opening 22 on the die head 2 of the upper mold is fitted with the connecting columns 41 and then The molten production material can be injected into the cavity 21 through the upper mold. After the production material cools and solidifies, the production material is coated on the mold core 4 to form a composite insulator. Then, the upper mold is controlled to separate from the mold frame 1, and the composite insulator is taken out from the cavity 21. During the demoulding process, the die head 2 and the module 3 on the upper mold and the mold frame 1 may be adhered to a small part of the surface of the composite insulator. The latch 13 can be engaged with the latch groove 12 to prevent the die head 2 and the module 3 from being displaced in the vertical direction inside the mold groove 11, thereby preventing the upper mold from pulling the module 3 or the die head 2 out of the mold groove 11 through the composite insulator, and also preventing the die head 2 or the module 3 on the upper mold from falling off under the action of gravity.To change the length of the insulator being produced, reverse the handle 5211 to separate the pressing plate 51 from the die head 2. Remove the die head 2 near the pressing plate 51 from the die groove 11. Then, increase or decrease the number of modules 3 as needed, and then install the die head 2 and mold core 4 according to the above steps. This eliminates the need to replace the entire mold, facilitating work and improving production efficiency.

[0037] A first baffle 621 is fixedly provided on one end of the rotating shaft 62 away from the second bracket 66 , and a second baffle 651 is fixedly provided on the first bracket 65 .

[0038] With this arrangement, when installing the mold core 4, the staff can press the button 672 downward, and the button 672 compresses the spring 676 through the spring shaft 674 and drives the first slide shaft 6721 to slide downward inside the second slide groove 6711, and at the same time drives the limit pin 673 to slide downward inside the opening 6713. When the first slide shaft 6721 contacts the bottom of the second slide groove 6711, continue to press the button 672 downward and push the button 672 to move away from the limit rod 61. The button 672 drives the first slide shaft 6721 to slide inside the second slide groove 6711 and pushes the spring sleeve through the spring shaft 674. 675 moves, the spring sleeve 675 drives the second sliding shaft 6751 to slide inside the third sliding groove 6712, and after the first sliding shaft 6721 contacts the other side of the second sliding groove 6711, the button 672 can no longer move. At the same time, the button 672 drives the limiting pin 673 away from the limiting rod 61 until it is separated from the limiting rod 61, and then the button 672 is released, and the spring 676 pushes the button 672 to move upward through the spring shaft 674, and the first sliding shaft 6721 slides to the top of the second sliding groove 6711; because the torsion spring 63 continuously applies a torsional force to the limiting rod 61, when the limiting pin 673 and the limiting After the rod 61 is separated, the limiting rod 61 drives the rotating shaft 62 to rotate under the action of the torsion spring 63, and the rotating shaft 62 drives the first baffle 621 to rotate.
