Description

Technical Field

[0001] This utility model relates to the field of high-voltage insulator production and processing technology, and in particular to a processing mold for epoxy resin high-voltage insulators for GIS. Background Technology

[0002] High-voltage insulators for GIS are commonly used in power facilities such as high-voltage transmission lines and substations. With the rapid development of the power industry, the demand for high-voltage insulators is constantly increasing. Mold structure improvement needs to increase production efficiency and reduce production costs while ensuring product quality. For example, optimizing the mold structure design can shorten the molding cycle and increase the mold's service life. The power industry has strict standards and specifications for the performance and quality of insulators, and mold structure improvement must meet the requirements of these standards and specifications. This prompts mold manufacturers to continuously improve mold structures to meet the updating and improvement of industry standards. Currently, high-voltage insulator processing molds suffer from low assembly and disassembly efficiency, and the disassembly process can damage the product, affecting the product qualification rate. Therefore, a new epoxy resin high-voltage insulator processing mold for GIS needs to be developed. Summary of the Invention

[0003] The purpose of this utility model is to provide a processing mold for epoxy resin high-voltage insulators for GIS, thereby solving the technical problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This utility model discloses a processing mold for epoxy resin high-voltage insulators for GIS, including a lower mold and a flange. The flange has a detachable transition ring plate at its end, and two positioning bosses are symmetrically fixed on the transition ring plate. The lower mold has a receiving groove on the side near the flange that matches the end of the flange and the contour of the transition ring plate. Two positioning grooves that match the two positioning bosses are symmetrically formed on the peripheral wall of the receiving groove. The lower mold has a plurality of threaded through holes evenly formed along the circumference, and each threaded through hole has a set screw that is threadedly connected to it.

[0006] Furthermore, two first threaded holes are symmetrically formed on the peripheral wall of the flange, and each of the positioning bosses is provided with a second threaded hole of the same specification as the first threaded hole. The transition ring plate is fixedly connected to the flange by two connecting screws that pass through the corresponding second threaded hole and the first threaded hole respectively.

[0007] Furthermore, a nylon pad is fixedly provided at one end of each set screw near the transition ring plate.

[0008] Furthermore, the transition ring plate is made of 45 steel.

[0009] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0010] This invention utilizes a detachable filter ring plate that is fixedly connected to a flange. After connection, the positioning boss on the transition ring plate engages with the positioning groove on the lower mold to achieve proper positioning of the flange and the lower mold. During demolding, the ejector screws on the lower mold can be used directly for convenient and quick removal, preventing difficulty in separating the flange from the mold or tearing of the product in the middle. This invention significantly improves the speed of mold assembly and disassembly in the processing of GIS epoxy resin high-voltage insulators, saving time and costs, and significantly increasing the product qualification rate during demolding.

[0020] like Figures 1-7 As shown, a processing mold for epoxy resin high-voltage insulators for GIS includes a lower mold 2 and a flange 3.

[0021] A transition ring plate 4 is detachably mounted on the end of the flange 3, and two positioning bosses 5 are symmetrically fixed on the transition ring plate 4. In this embodiment, two first threaded holes 6 are symmetrically opened on the peripheral wall of the flange 3, and each positioning boss 5 is provided with a second threaded hole 7 of the same specification as the first threaded hole 6. The transition ring plate 4 is fixedly connected to the flange 3 by two connecting screws that pass through the corresponding second threaded hole 7 and first threaded hole 6 respectively.

[0022] The lower mold 2 has a receiving groove 8 on the side near the flange 3, which matches the end of the flange 3 and the contour of the transition ring plate 4. Two symmetrical positioning grooves 9 are formed on the peripheral wall of the receiving groove 8, each matching one of the two positioning bosses 5. After the transition ring plate 4 is fixedly connected to the flange 3, both can be installed together in the receiving groove 8 of the lower mold 2. The two positioning bosses on the transition ring plate cooperate with the positioning grooves of the lower mold, ensuring the direction and position of the flange and achieving effective positioning of the flange.

[0023] The lower mold 2 has multiple threaded through holes 10 evenly distributed circumferentially, and each threaded through hole 10 has a set screw 1 threadedly connected to it. When demolding is required, each set screw 1 can be rotated to separate the lower mold 2 from the transition plate 4, thereby removing the lower mold 2 and quickly completing the demolding process. In addition, a nylon pad is fixedly provided at one end of each set screw 1 near the transition ring plate 4 to reduce damage to the transition plate caused by the set screw. In this embodiment, the transition ring plate 4 is made of hard metal materials such as 45 steel or pure iron to improve its service life.

[0024] After removing the lower mold, remove the screws between the transition ring plate and the flange to separate them, and you can get the complete product. The transition plate can be cleaned and reused.

[0025] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
