Description

Technical Field

[0001] This utility model relates to the field of mold making technology, specifically to a new energy hard copper bar molding mold structure. Background Technology

[0002] As a key conductive component, the new energy hard copper bus is widely used in battery modules, power equipment and other fields. Its molding quality directly affects the reliability of electrical connections and system safety.

[0003] In existing technologies, the bending and forming of hard copper bars mostly adopts traditional stamping dies, which have certain limitations in terms of positioning structure. For example, common dies only use fixed positioning blocks or stop pins to limit the sheet material, which cannot effectively adapt to the processing requirements of sheet materials of different sizes. Every time a product size is changed, the entire set of dies must be replaced or the entire positioning device must be readjusted. The adjustment process is cumbersome and time-consuming, which seriously affects production efficiency and the versatility of dies.

[0004] Therefore, there is an urgent need for a hard copper bar forming mold structure that is highly versatile, highly precise, and easy to adjust. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a new energy hard copper bar forming mold structure to solve problems such as inaccurate positioning, poor versatility, and inconvenient adjustment in existing hard copper bar bending molds. Through the synergistic effect of detachable positioning blocks and positioning blocks, rapid and accurate positioning of plates of different sizes is achieved, improving bending accuracy and production efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A new energy hard copper plate forming mold structure includes an upper mold base and a lower mold base. The upper mold base is provided with an upper mold forming block, and the lower mold base is provided with a lower mold forming block that cooperates with the upper mold forming block. The lower mold forming block has a plurality of positioning blocks inside, the tops of which protrude from the forming surface of the lower mold forming block and form a lateral limiting structure for fixing the plate. The lower mold base is provided with positioning blocks perpendicular to the positioning blocks. The positioning blocks are detachably provided on the side of the lower mold forming block, and the positioning blocks on both sides form a longitudinal limiting structure for fixing the plate.

[0007] Furthermore, the upper die forming block is provided with a clearance groove corresponding to the positioning block, and the forming surface of the upper die forming block and the forming surface of the lower die forming block work together to bend the sheet material.

[0008] Furthermore, the forming surface of the lower mold forming block includes a support part one and a support part two for supporting the horizontally placed plate material.

[0009] Furthermore, the side of the lower mold forming block is provided with a mounting groove for installing the positioning block, and the positioning block is detachably installed in the mounting groove by fasteners.

[0010] Furthermore, the positioning block is L-shaped in general and includes a fixed part and a vertical part of integral structure. The fixed part is disposed in the mounting groove, and the vertical part is used to abut against the end of the sheet material.

[0011] Furthermore, a pad is provided between the upper mold base and the upper mold forming block.

[0012] Furthermore, the upper mold base is provided with a guide sleeve, and the lower mold base is provided with a guide post adapted to the guide sleeve, and a spring is sleeved on the guide post.

[0013] Compared with existing technologies, the technical solution of this patent achieves the following beneficial effects: 1. By using detachable positioning blocks that are perpendicular to the positioning blocks, the sheet metal is fully limited in all directions on the left, right, top, and bottom ends, effectively preventing the sheet metal from shifting during bending. More importantly, the detachable positioning block design allows for quick replacement of blocks of different thicknesses to adapt to the processing requirements of sheet metal of different lengths, and effectively adjusts the length of the sheet metal from the bending section to the front and rear ends to meet different processing requirements, significantly improving the versatility and production flexibility of the mold. 2. The support part of the lower mold forming surface provides a stable horizontal reference, further improving positioning accuracy and product consistency; the guide post and guide sleeve structure cooperates with the spring to ensure the alignment accuracy of the upper and lower molds and the smoothness of demolding, thereby improving production efficiency and automation.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] See Figure 1-6 As shown, this embodiment provides a new energy hard copper bar forming mold structure, including an upper mold base 1 and a lower mold base 2. The upper mold base 1 is provided with an upper mold forming block 3, and the lower mold base 2 is provided with a lower mold forming block 4 that cooperates with the upper mold forming block 3. The lower mold forming block 4 is provided with a plurality of positioning blocks 5 inside. The top of the plurality of positioning blocks 5 protrudes from the forming surface of the lower mold forming block 4 and forms a lateral limiting structure for fixing the sheet material 12. The lower mold base 2 is provided with positioning blocks 6 that are perpendicular to the positioning blocks 5. The positioning blocks 6 are detachably provided on the side of the lower mold forming block 4. The positioning blocks 6 on both sides form a longitudinal limiting structure for fixing the sheet material 12. This technical solution, by setting a detachable positioning block 6 perpendicular to the positioning block 5 in the lower die base 2, forms a precise limit on the upper and lower ends of the sheet metal 12, effectively preventing the sheet metal 12 from moving back and forth during the bending process. At the same time, the detachable design allows for the replacement of positioning blocks 6 of different thicknesses to accommodate sheet metal of different lengths, and effectively adjusts the length of the sheet metal bending section to the front and rear ends to meet different processing requirements, significantly improving the versatility and production flexibility of the mold. The importance of the detachable positioning blocks 6 of different thicknesses will be mentioned in detail below.

[0018] The upper die forming block 3 is provided with a relief groove 30 corresponding to the positioning block 5. The forming surface of the upper die forming block 3 and the forming surface of the lower die forming block 4 work together to bend the sheet metal 12. The relief groove 30 provides precise accommodating space for the positioning block 5, avoiding interference between the upper die and the positioning block when the die is closed. At the same time, the synergistic effect of the forming surfaces of the upper and lower dies ensures the uniform distribution of bending force, effectively preventing the sheet metal from twisting and deforming during the bending process, and improving bending accuracy and product quality.

[0019] The forming surface of the lower die forming block 4 includes a support part 40 and a support part 41 that support the sheet metal 12 horizontally. The support part 40 and the support part 41 form a stable horizontal support platform on the lower die forming surface, providing a precise positioning reference for the sheet metal 12 before stamping and bending, ensuring that the sheet metal 12 remains horizontal during processing, avoiding positioning deviations caused by unstable support, providing a reliable positioning basis for subsequent bending processes, and improving processing accuracy and product consistency.

[0020] The lower mold forming block 4 has a mounting groove 42 on its side for mounting the positioning block 6. The positioning block 6 is detachably mounted in the mounting groove 42 by fasteners 7 (such as bolts). The combination design of the mounting groove 42 and the fasteners 7 enables quick disassembly and replacement of the positioning block 6. At the same time, the wall of the mounting groove 42 effectively restricts the left and right movement and rotation of the positioning block 6, ensuring the stability of the positioning block 6 in the working state and improving the positioning accuracy and reliability.

[0021] The positioning block 6 is L-shaped and includes a fixed part 60 and a vertical part 61, both integrally formed. The fixed part 60 is disposed within the mounting groove 42, and the vertical part 61 abuts against the end of the sheet metal 12. The L-shaped positioning block 6 is securely installed by the fixed part 60 embedding into the mounting groove 42, and the vertical part 61 provides abutment against the end of the sheet metal 12. When producing sheet metal of large length, since the original positioning blocks 6 on both sides are no longer suitable for fixing the upper and lower limits of the sheet metal, it is necessary to replace and select blocks suitable for the current upper and lower limits of the sheet metal, i.e., select a thinner vertical part 61 block to ensure that the large-length sheet metal can be fixed smoothly. Similarly, when producing sheet metal of small length, a thicker vertical part 61 block is selected to ensure that the small-length sheet metal can be fixed smoothly. When it is necessary to adjust the length of the sheet metal bending section to the front or rear end, the positioning block 6 on one side can be replaced to increase or decrease the length of the sheet metal bending section to the end, so as to meet different processing parameter requirements.

[0022] A pad 8 is provided between the upper die holder 1 and the upper die forming block 3. The pad 8 effectively buffers the impact stress during the stamping process and prevents damage to the upper die forming block. At the same time, the modular design allows maintenance to be performed by simply replacing the pad or a single module, which greatly simplifies the maintenance process and reduces the cost of use.

[0023] The upper mold base 1 is equipped with a guide sleeve 9, and the lower mold base 2 is equipped with a guide post 10 that is compatible with the guide sleeve 9. A spring 11 is fitted on the guide post 10. The cooperation between the guide sleeve 9 and the guide post 10 ensures the precise alignment of the upper and lower molds, avoiding mold misalignment. The spring provides a stable demolding force, ensuring smooth return of the upper mold and improving production efficiency and automation.

[0024] In operation, the sheet metal 12 is placed on the support part 40 and support part 41 of the lower die forming block 4. The locating block 5 provides left and right positioning, while the locating blocks 6 on both sides provide up and down positioning, thus initially fixing the sheet metal 12. The upper die base 1 is pressed down under the drive of the press, and the upper die forming block 3 and the lower die forming block 4 work together to bend the sheet metal 12. The clearance groove 30 provides space for the locating block 5, preventing interference. After bending, the upper die returns, and the spring 11 assists in demolding. If different lengths of sheet metal are required, the length from the bending section to the end can be adjusted by replacing the locating blocks of different thicknesses (e.g., thinner blocks for large-sized sheets and thicker blocks for small-sized sheets) or by replacing the blocks on one side, thus meeting diverse processing needs.
