[0002] With the rapid development of the power industry, high-voltage cables are playing an increasingly important role in power transmission and distribution. However, the connection of high-voltage cables is a technical challenge, especially the interface welding part.

[0003] In the traditional cable interface welding process, since the specifications and diameters of the cable cores may vary, it is usually necessary to prepare a variety of matching molds. Whenever a cable of different specifications or diameters is encountered, the corresponding mold needs to be changed. This process not only increases the complexity of the operation and makes the welding work more cumbersome, but also seriously affects the work efficiency. Furthermore, frequent mold changes are not only time-consuming and labor-intensive, but may also lead to a decline in welding quality due to improper mold changes. Therefore, a special mold for casting and welding high-voltage cable interfaces is needed. Utility Model Content

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a special mold for casting and welding high-voltage cable interfaces, which has the following advantages:

[0018] 1. This high-voltage cable interface casting and welding mold, through its cable adjustment and fixing components, can adapt to cable cores of different thicknesses. Furthermore, even when welding two cables with different diameters, the shrinking cable locking plate can stably fix them. This allows the mold to complete the welding of cable joints of various specifications, improving the efficiency of cable welding and avoiding the problem of needing to change to a matching mold when welding different specifications of cables in the traditional method. This, to a certain extent, improves the efficiency of cable welding.

[0019] 2. This high-voltage cable interface casting and welding special mold, when the cable locking plate is gradually moved, the flared opening on its surface can contact the opening of the cable fixing port. Under its force, the flared opening of the cable locking plate can contract inward, thereby clamping and fixing the cable core. Furthermore, since the two cable locking plates are close to each other and locked, the two cable cores can also be kept close to each other under its force. This makes the cable core more firmly and stably fixed during subsequent casting and welding. Attached Figure Description

[0028] Please see Figure 1-3 This utility model provides a new technical solution: a special mold for casting and welding of high voltage cable interfaces, including a casting mold body 1, which is a two-part combination. Multiple positioning and alignment blocks 15 are provided inside the casting mold body 1 for positioning. Two cable fixing ports 2 are fixedly connected to the casting mold body 1. Cable adjustment and fixing components are provided on the casting mold body 1.

[0029] The cable adjustment and fixing assembly is used to fix the cable core to be welded. The cable adjustment and fixing assembly includes a cable locking plate 3, a fixing ear 5, a C-shaped plate 6, a U-shaped block 9, a socket 12, a sliding sleeve 13, a locking bolt 14, and a limit alignment block 15.

[0030] The two cable locking pieces 3 in the cable adjustment and fixing assembly are respectively set in the corresponding cable fixing ports 2, and the opposite ends of the two cable locking pieces 3 are both set in a trumpet shape;

[0031] The outer surface of the cable locking plate 3 has multiple movable grooves 4, which are evenly arranged in a circumferential array. Multiple fixed ears 5 are fixedly connected to the outer surface of the opening of the cable locking plate 3. The cable locking plate 3 is a two-part combination.

[0032] Furthermore, two C-shaped plates 6 are respectively set on the outside of the corresponding cable fixing port 2, and multiple waist hole fixing blocks 7 are fixedly connected to each C-shaped plate 6.

[0033] Furthermore, the two corresponding waist hole fixing blocks 7 are located on the outside of the two designated fixing ears 5, and a first safety pin 8 is provided between the corresponding waist hole fixing block 7 and the fixing ear 5.

[0034] Furthermore, the first safety pin 8 is used to connect the waist hole fixing block 7 and the two cable locking pieces 3, and the two U-shaped blocks 9 are respectively fixedly connected to the outer surface of the corresponding C-shaped plate 6.

[0035] Furthermore, a connecting rod 11 is provided between the two U-shaped blocks 9, and multiple insertion holes 12 are respectively opened at both ends of the connecting rod 11.

[0036] Furthermore, a second safety pin 10 is provided between the U-shaped block 9 and the corresponding insertion hole 12. The second safety pin 10 is used to connect the U-shaped block 9 and the connecting rod 11. The second safety pin 10 and the first safety pin 8 are both existing technologies and will not be described in detail here. The two sliding sleeves 13 are rotatably connected inside the U-shaped block 9.

[0037] Furthermore, the locking bolt 14 is slidably connected between the two sliding sleeves 13, and two nuts are threaded onto the locking bolt 14. The locking bolt 14 is used to bring the two sliding sleeves 13 closer together and separate them.

[0038] Furthermore, in use, the cable cores to be welded are stripped out, and two cable cores are initially fixed and aligned using external clamps. Then, the two casting mold bodies 1 are joined together on the cable cores. After the limiting alignment blocks 15 on the casting mold bodies 1 are joined and aligned, they are placed into the two cable fixing holes 2. Then, the casting mold bodies 1 are clamped using external clamps. At this time, the cable locking piece 3 is installed between the opening of the cable core and the cable fixing hole 2. Then, the C-shaped plate 6 is installed on both sides of the fixing ear 5 to overlap. The first safety pin 8 is passed through the corresponding waist hole fixing block 7 and fixing ear 5. Then, the connecting rod 11 is installed between the two U-shaped blocks 9. The second safety pin 10 is passed through and connected together. Finally, the locking bolt 14 and its nut are tightened. This causes the two sliding sleeves 13 to move away from each other, which allows the U-shaped block 9 to move the two C-shaped plates 6 closer together. This allows the two C-shaped plates 6 to move the fixing ears 5 and the cable locking plates 3 towards the opening between the cable core and the cable fixing port 2 through the waist hole fixing block 7 on them. As the cable locking plates 3 move gradually, the flared opening on its surface can contact the opening of the cable fixing port 2. The cable locking plates 3 are subjected to its force, which causes the flared opening of the cable locking plates 3 to contract inward, thereby clamping and fixing the cable core. Since the two cable locking plates 3 are locked close to each other, the two cable cores can also be kept close to each other by its force. This makes the cable core more firmly and stably fixed during subsequent pouring and welding.

[0039] Furthermore, the cable adjustment and fixing components can be adapted to cable cores of different thicknesses. Even when welding two cables with different diameters, the shrinkable cable locking plate 3 can stably fix them. This allows the mold to complete the welding of cable joints of various specifications, improving the efficiency of cable welding and avoiding the problem of needing to change to a matching mold when welding different specifications of cables in the traditional method. This improves the efficiency of cable welding to a certain extent.

[0040] Working principle: During use, the cable cores to be welded are stripped out, and two cable cores are initially aligned using external clamps. Then, the two casting mold bodies 1 are joined together on the cable cores. After the limiting alignment blocks 15 on the casting mold bodies 1 are aligned, they are placed into the two cable fixing holes 2. The casting mold bodies 1 are then clamped using another external clamp. At this point, the cable locking plate 3 is installed between the cable cores and the openings of the cable fixing holes 2. Then, the C-shaped plates 6 are installed on both sides of the fixing ears 5 to overlap. The first safety pin 8 is passed through the corresponding waist hole fixing block 7 and fixing ear 5. Then, the connecting rod 11 is installed between the two U-shaped blocks 9, and the second safety pin 10 is used to connect them. Finally, the locking bolt 14 and its nut are tightened. This causes the two sliding sleeves 13 to move away from each other, which allows the U-shaped block 9 to move the two C-shaped plates 6 closer together. This allows the two C-shaped plates 6 to move the fixing ears 5 and the cable locking plates 3 towards the opening between the cable core and the cable fixing port 2 through the waist hole fixing block 7 on them. As the cable locking plates 3 move gradually, the flared opening on its surface can contact the opening of the cable fixing port 2. The cable locking plates 3 are subjected to its force, which causes the flared opening of the cable locking plates 3 to contract inward, thereby clamping and fixing the cable core. Since the two cable locking plates 3 are locked close to each other, the two cable cores can also be kept close to each other by its force. This makes the cable core more firmly and stably fixed during subsequent pouring and welding.
