[0003] The forming mold usually consists of a mold base, an upper mold, a lower mold and other mechanisms. When in use, the mold base is used to support and position other components, and the lower mold is installed on the mold base. The raw material is then heated and introduced into the forming cavity of the lower mold. It is then pressed onto the top of the lower mold through the upper mold using a hydraulic press. After the claw pole cools and forms, it is removed to complete the claw pole forming work.

[0004] In the current existing technology, traditional claw pole production molding dies are usually equipped with a set of molds for claw poles of one size, and most of the molds are integral structures. When producing claw poles of different sizes, it is inconvenient for workers to replace the molds. Replacement consumes a lot of time and energy, affecting the production efficiency of the claw poles and reducing the practicality and work efficiency of the molds.

[0005] Therefore, in order to solve the above problems, a forming die for claw pole production is proposed. Utility Model Content

[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Specific examples are given below.

[0026] See also Figure 1 - Figure 5The utility model provides a forming mold for claw pole production, including a mold base 1, and two mounting grooves 2 are provided at both ends of the mold base 1. A positioning groove 3 is provided in the middle of the mold base 1, and the inner wall of the positioning groove 3 is fitted and connected to the lower mold 4. A plurality of fixing blocks 5 are fixedly connected to the outer side of the top of the lower mold 4, and a plurality of sockets 12 are provided on the outer side of the bottom of the lower mold 4, and the plurality of sockets 12 are arranged in a circular array. A plurality of slide grooves 15 are provided at the bottom of the positioning groove 3, and the inner wall of each slide groove 15 is fixedly connected to an electric push rod 16. One end of each electric push rod 16 is fixedly connected to a push plate 14, and the outer wall of the push plate 14 is slidably connected to the inner wall of the slide groove 15 via the electric push rod 16. An insertion rod 13 is fixedly connected to one side of each push plate 14, and the outer wall of one end of each insertion rod 13 is snap-fitted and connected to the inner wall of the socket 12 via the push plate 14. One side of each push plate 14 is fitted and connected to the outer wall of the lower mold 4 via the insertion rod 13 , and the bottom outer wall of the lower mold 4 is fitted and connected to the inner wall of the positioning groove 3 via a plurality of insertion holes 12 .

[0027] During operation, the mold base 1 is placed in the claw-pole forming machine and secured to the machine using bolts inserted through the mounting slots 2. The lower mold 4 is then placed into the positioning slots 3, with the socket 12 aligned with one side of the insertion rod 13. The electric push rod 16 then pushes the push plate 14 to slide within the slide slot 15, inserting one end of the insertion rod 13 into the socket 12. The push plate 14 then fits against the outside of the lower mold 4, securing it within the positioning slots 3. This prevents shaking between the molds during claw-pole manufacturing, improves structural stability and efficiency, and enhances the claw-pole forming effect. When the lower mold 4 needs to be replaced, the push plate 14 is retracted into the inside of the slide groove 15 by contracting the electric push rod 16, so that the insertion rod 13 is disengaged from the socket 12, and then the fixing block 5 on the outside of the top of the lower mold 4 is pulled to quickly remove it, thereby reducing the jamming during the disassembly process, making it easier for workers to operate, reducing the time and energy consumed during replacement, and improving the production efficiency of the claw pole, thereby improving the practicality and work efficiency of the mold.

[0028] Further, such as Figure 2 and Figure 3 As shown, both ends of the top of the mold base 1 are fixedly connected to limit rods 6. The two limit rods 6 are symmetrically arranged on either side of the lower mold 4, and a positioning ring is slidably connected to the outer wall of each limit rod 6. The outer walls of the two positioning rings 7 are fixedly connected to the upper mold base 8. The upper mold base 8 is slidably connected to the outer walls of the limit rods 6 via the two positioning rings 7, and the upper mold base 8 is arranged horizontally between the limit rods 6 and the mold base 1. Multiple mounting grooves 2 are also formed at both ends of the positioning rings 7, and an upper mold 9 is fixedly connected to one side of the bottom of the upper mold base 8. One side of the upper mold 9 is connected to the top of the lower mold 4 through the upper mold base 8.

[0029] During operation, the upper die base 8 is moved to fit the positioning collars 7 around the outer sides of the limit rods 6. After aligning one side of the upper die base 8 with one end of the hydraulic press, the upper die base 8 is secured to the bottom of the hydraulic press using bolts or other tools inserted through the mounting slots 2. The limit rods 6 prevent the upper die base 8 from misaligning during movement, while the positioning collars 7 reduce friction between the limit rods 6 and the upper die base 8, extending the service life of the structure. Furthermore, when the upper die base 8 is driven to move, the upper die 9 is stably attached to the top of the lower die 4, thereby improving the claw pole forming effect.

[0030] Further, such as Figure 4 and Figure 5 As shown, the bottom outer side of the lower mold 4 is provided with a plurality of slots 10, the inner wall of each slot 10 is fitted with a block 11, and one side of each block 11 is fixedly connected to the inner wall of the positioning slot 3. One side of each push plate 14 is fixedly connected to a return spring 17, each return spring 17 is sleeved on the outer side of the electric push rod 16, and the other end of each return spring 17 is fixedly connected to one side of the slide slot 15.

[0031] During operation, by placing the lower mold 4 inside the positioning groove 3, aligning the slot 10 at the bottom of the lower mold 4 with the outside of the block 11, and then pressing the lower mold 4, the slot 10 can be completely stuck on the outside of the block 11, and the lower mold 4 can be positioned and installed so that the outside of the socket 12 is always aligned with one side of the slide 15, so that the insertion rod 13 can be stably inserted into the inside of the socket 12, preventing the lower mold 4 from being misaligned and causing the insertion rod 13 to be unable to insert into the socket 12, thereby improving the installation efficiency of the lower mold 4. When the push plate 14 is pushed to move by the electric push rod 16, the elastic force of the return spring 17 can reduce the consumption of kinetic energy and reduce the jamming of the push plate 14 when moving inside the slide 15, thereby improving the service life and practicality of the structure.

[0032] Working principle: Place the mold base 1 in the claw pole forming equipment and then secure the mold base 1 to the equipment using bolts or other means passing through the mounting slot 2. Place the lower mold 4 into the positioning slot 3 and align the slot 10 at the bottom of the lower mold 4 with the outside of the block 11. Press the lower mold 4 to completely engage the slot 10 on the outside of the block 11, so that the socket 12 is aligned with one side of the insert rod 13. Then, use the electric push rod 16 to push the push plate 14 to slide inside the slide 15. The elastic force of the return spring 17 reduces the jamming of the push plate 14 when moving inside the slide 15, thereby inserting one end of the insert rod 13 into the socket 12, securing the lower mold 4 inside the positioning slot 3. Move the upper mold base 8 to fit the positioning rings 7 onto the outside of the limit rod 6, and then secure the upper mold base 8 to the bottom of the hydraulic press using bolts or other means passing through the mounting slot 2. The limiting rod 6 can prevent the upper mold base 8 from being misaligned during movement, so that the upper mold 9 can be stably attached to the top of the lower mold 4 when the upper mold base 8 moves. When the lower mold 4 needs to be replaced, the push plate 14 is retracted into the inner part of the slide groove 15 by contracting the electric push rod 16, thereby disengaging the insertion rod 13 from the insertion hole 12. Then, the fixing block 5 on the outer side of the top of the lower mold 4 can be pulled out quickly.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
