In addition, the hexagonal flange bolt can also improve the reliability, anti-loosening ability and fatigue strength of the bolt connection by applying a pre-tightening force, thereby enhancing the tightness and stiffness of the threaded connection body; the hexagonal die is a common type of die, and its name comes from its shape characteristics, that is, six equal-length sides. The hexagonal die is usually made of high-quality steel and has good hardness, toughness and wear resistance.

[0021] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1 to 6 , in the embodiments of the present utility model, a hexagonal die for a hexagonal flange bolt bundle includes a sealing cover plate 1. A pouring pipeline 2 is fixedly installed at the left end of the sealing cover plate 1. A connecting seat 7 is fixedly installed in the middle of the sealing cover plate 1. A first hexagonal die body 3 and a second hexagonal die body 5 are arranged below the sealing cover plate 1. Multiple groups of the first hexagonal die body 3 and the second hexagonal die body 5 are arranged below the sealing cover plate 1. A flow guide groove 4 is formed between the first hexagonal die body 3 and the second hexagonal die body 5. A cooling mechanism 6 is arranged below the first hexagonal die body 3 and the second hexagonal die body 5;

[0023] The first hexagonal die body 3 and the second hexagonal die body 5 have an interconnected structure, which is also beneficial to the flow of the molten metal, enabling the die to pour multiple hexagonal die bodies at one time, significantly improving the production efficiency. At the same time, it makes the forming process of the die body more uniform, improving the quality and precision of the die body; the flow guide groove 4 can guide the flow of the molten metal and fill multiple hexagonal die bodies, ensuring the forming effect of the die body;

[0024] The cooling mechanism 6 includes a first copper plate 601, a first aluminum sheet 602, a silica gel sheet 603, a second copper plate 604, a second aluminum sheet 605, a first refrigeration fan 606 and a second refrigeration fan 607. The lower ends of the first hexagonal die body 3 and the second hexagonal die body 5 are fixedly installed with the first copper plate 601. The upper surface of the first copper plate 601 is installed with the first aluminum sheet 602. Multiple groups of first aluminum sheets 602 are distributed on the outer sides of the first hexagonal die body 3 and the second hexagonal die body 5. The lower end of the first copper plate 601 is fixedly installed with the silica gel sheet 603. The lower end of the silica gel sheet 603 is fixedly installed with the second copper plate 604. The lower end of the second copper plate 604 is fixedly installed with the second aluminum sheet 605. Multiple groups of second aluminum sheets 605 are distributed on the lower surface of the second copper plate 604 from left to right. The first refrigeration fan 606 is arranged on the right side inside the second aluminum sheet 605, and the second refrigeration fan 607 is arranged on the left side inside the second aluminum sheet 605;

[0025] By using the first refrigeration fan 606 and the second refrigeration fan 607 for refrigeration, the second aluminum sheets 605 around the first refrigeration fan 606 and the second refrigeration fan 607 are quickly cooled. After the temperatures of multiple second aluminum sheets 605 are reduced, they will transfer to the second copper plate 604 and the silica gel sheet 603. The highly heat-conductive second copper plate 604 and silica gel sheet 603 will transfer the low temperature to the first copper plate 601 and the first aluminum sheet 602. Then, the hexagonal die body is cooled by the first copper plate 601 and the first aluminum sheet 602, and the cooling operation can be carried out on multiple hexagonal die bodies simultaneously.

[0026] The working principle of the present utility model is as follows: This hexagonal mold for hexagonal flange bolt bundles is composed of a sealing cover plate 1, a pouring pipe 2, a first hexagonal mold body 3, a diversion groove 4, a second hexagonal mold body 5, a cooling mechanism 6, and a connecting seat 7. Before using this hexagonal mold for hexagonal flange bolt bundles, it is necessary to pre-connect this connecting seat 7 with a hydraulic cylinder, use the hydraulic cylinder to drive the displacement of the sealing cover plate 1, then connect the first refrigerating fan 606 and the second refrigerating fan 607 to electricity and connect them to a control terminal. When using this hexagonal mold for hexagonal flange bolt bundles, first start the hydraulic cylinder to push down the connecting seat 7 and the sealing cover plate 1, so that the sealing cover plate 1 covers the first hexagonal mold body 3 and the second hexagonal mold body 5. Pour molten metal into the first hexagonal mold body 3 through the pouring pipe 2, etc. The molten metal continuously flows through the diversion groove 4 and fills multiple hexagonal mold bodies. After completing this operation, wait for the hexagonal mold bodies to be shaped, and then immediately perform a cooling operation. Just activate the cooling mechanism 6 and start the first refrigerating fan 606 and the second refrigerating fan 607 inside the cooling mechanism 6. The first refrigerating fan 606 and the second refrigerating fan 607 rotate at high speed to quickly cool the second aluminum sheets 605 around the first refrigerating fan 606 and the second refrigerating fan 607. After the temperatures of multiple second aluminum sheets 605 decrease, they will transfer to the second copper plate 604 and the silica gel sheet 603. The highly heat-conductive second copper plate 604 and silica gel sheet 603 will transfer the low temperature to the first copper plate 601 and the first aluminum sheet 602. Then, cool the hexagonal mold bodies through the first copper plate 601 and the first aluminum sheet 602. Multiple hexagonal mold bodies can be cooled simultaneously, effectively improving the efficiency of cooling the hexagonal mold bodies and the overall efficiency of manufacturing the hexagonal mold bodies. In summary, the first hexagonal mold body 3, the diversion groove 4, and the second hexagonal mold body 5 adopt a multi-group interconnection method, which can achieve the effect of pouring multiple hexagonal mold bodies at one time. A total of thirteen hexagonal mold bodies, including the first hexagonal mold body 3 and the second hexagonal mold body 5, can be poured at one time, thus realizing a batch manufacturing effect. The cooling mechanism 6 cooperates with the thirteen hexagonal mold bodies and can cool multiple hexagonal mold bodies at one time, improving the efficiency of cooling the mold and also the overall efficiency of the production process of the hexagonal mold bodies.
