Description

Technical Field

[0001] This utility model relates to the field of new energy hard copper bar production technology, and in particular to a one-time molding structure for a new energy hard copper bar. Background Technology

[0002] Currently, the processing of hard copper bars in the industry mostly adopts a multi-step forming process. First, the copper material is initially cut by cutting equipment, then it is bent multiple times by bending machine to obtain the required shape, and finally the dimensional accuracy is adjusted by grinding, correction and other processes. However, this type of process has two main drawbacks. First, the multi-step processing can lead to cumulative errors in the copper bars. This is especially true for hard copper bars with complex structures such as the "N" shape. Multiple positioning and bending operations can make it difficult for the formed copper bars to meet high standards in terms of dimensional consistency and angular accuracy, increasing the difficulty of subsequent assembly. Second, the step-by-step processing is cumbersome and requires frequent changes of equipment and tooling, which not only extends the production cycle but also increases labor and equipment investment costs. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model proposes a one-piece molded structure for a new energy hard copper bar.

[0004] This utility model proposes a one-time molding structure for a new energy hard copper bar, including a lower mold and an upper mold. The new energy hard copper bar is disposed between the lower mold and the upper mold. The lower mold and the upper mold respectively include a lower mold base and an upper mold base. A lower molding block and an upper mold molding block are respectively installed on the adjacent end faces of the lower mold base and the upper mold base. A lower molding groove and an upper mold molding groove are respectively formed on the adjacent end faces of the lower molding block and the upper mold molding block.

[0005] Furthermore, the lower molding block is internally connected to several fixing pins, the top of each fixing pin protruding from the upper surface of the lower molding block, and the upper molding block has several positioning holes inside, with the fixing pins corresponding to and fitting the positioning holes.

[0006] Furthermore, positioning pins are installed on both sides of the lower molding block, and the top of the positioning pins protrudes from the edge of the lower molding block.

[0007] Furthermore, the top of the lower mold base is symmetrically connected with positioning rods, and the lower surface of the upper mold base is symmetrically equipped with positioning rod sleeves. The positioning rods and positioning rod sleeves correspond to and are adapted to each other.

[0008] Furthermore, a spring is sleeved on the outside of the positioning rod, and the two ends of the spring abut against the lower mold base and the positioning rod sleeve, respectively.

[0009] Furthermore, the lower forming groove and the upper forming groove are complementary "N"-shaped structures, and are adapted to the forming shape of the new energy hard copper bar.

[0010] The beneficial effects of this utility model are as follows: By cooperating with the lower forming groove of the lower mold and the upper forming groove of the upper mold to form a complete cavity that fits the “N”-shaped hard copper bar, the copper material can be directly formed in one step. Unlike the existing multi-process step-by-step forming process in the industry, it does not require cutting, multiple bending, grinding and correction. It avoids the cumulative error of the copper bar caused by multiple positioning and bending operations, effectively improves the dimensional consistency and angular accuracy of hard copper bars with complex structures such as “N”-shaped ones, reduces the difficulty of subsequent assembly, and saves the steps of frequently changing equipment and tooling, significantly shortening the production cycle, while reducing labor and equipment investment and reducing processing costs.

[0013] Reference Figure 1-5 This utility model proposes a one-time molding structure for a new energy hard copper bar, including a lower mold 1 and an upper mold 2, which cooperate with each other to complete the one-time molding process of the new energy hard copper bar 3. The specific technical solution is as follows: The lower mold 1 is specifically composed of a lower mold base 11, a lower forming block 12, a lower forming groove 13, a fixing pin 14, a positioning pin 15, a positioning rod 16, and a spring 17. The lower forming block 12 is installed on the top end face of the lower mold base 11. The lower forming groove 13 is opened on the upper surface of the lower forming block 12. In order to ensure the stability of the copper bar during the forming process, several fixing pins 14 are connected inside the lower forming block 12. The top of each fixing pin 14 protrudes from the upper surface of the lower forming block 12. When placing the copper bar raw material to be processed, the fixing pin 14 can be inserted into the preset positioning hole of the raw material to effectively limit the displacement of the raw material in the horizontal direction. At the same time, positioning pins 15 are installed on both sides of the lower forming block 12. The top of the positioning pin 15 protrudes from the edge of the lower forming block 12 to further assist in positioning the raw material to be processed and prevent the raw material from shifting during the mold closing process. The upper mold 2 and lower mold 1 are structurally compatible and consist of an upper mold base 21, an upper mold forming block 22, an upper mold forming groove 23, a positioning hole 24, and a positioning rod sleeve 25. The upper mold forming block 22 is installed on the lower surface of the upper mold base 21, and the upper mold forming groove 23 is formed on the lower surface of the upper mold forming block 22. The lower forming groove 13 and the upper mold forming groove 23 are complementary "N" shaped structures and are completely compatible with the final forming shape of the new energy hard copper bar 3. When the mold is closed, the two together form a complete copper bar forming cavity. To ensure that the copper bar can be formed into a preset "N" shaped structure in one go, the upper mold forming block 22 has several positioning holes 24 inside. The position of the positioning holes 24 corresponds one-to-one with the position of the fixing pins 14 on the lower forming block 12, and the hole diameter matches the diameter of the fixing pins 14. During the mold closing process, the fixing pins 14 can be accurately inserted into the positioning holes 24 to achieve precise positioning of the upper mold forming block 22 and the lower forming block 12, ensuring the accuracy of cavity docking and avoiding deviation in the copper bar forming size due to mold misalignment. To achieve precise docking and stable opening and closing of the lower mold 1 and the upper mold 2, a positioning rod 16 is symmetrically connected to the top of the lower mold base 11. A positioning rod sleeve 25 is symmetrically installed on the lower surface of the upper mold base 21 corresponding to the position of the positioning rod 16. The outer diameter of the positioning rod 16 is matched with the inner diameter of the positioning rod sleeve 25. During the mold opening and closing process, the positioning rod 16 can slide up and down along the inner wall of the positioning rod sleeve 25 to guide the movement of the upper mold 2, ensuring that the upper mold 2 always moves along the preset trajectory and avoiding lateral deviation. At the same time, a spring 17 is sleeved on the outside of the positioning rod 16. The two ends of the spring 17 are tightly abutted against the top surface of the lower mold base 11 and the lower end surface of the positioning rod sleeve 25, respectively. When the mold is closed, the upper mold 2 moves downward, and the positioning rod sleeve 25 compresses the spring 17. The spring 17 generates an upward elastic reaction force, which can buffer the impact of the upper mold 2 on the lower mold 1 and reduce mold collision damage. When the mold is opened, the elastic force of the spring 17 can help push the upper mold 2 to return to its original position, making the opening and closing operation more convenient. In the actual molding process of the new energy hard copper bar 3, the copper bar raw material to be processed is first placed on the lower forming block 12 of the lower mold 1. The raw material is precisely positioned by the fixing pin 14 and the positioning pin 15 to ensure that the position of the raw material meets the processing requirements. Then, the upper mold 2 is driven to move downward. Under the guidance of the positioning rod 16 and the positioning rod sleeve 25, the upper mold 2 moves downward smoothly until the lower forming block 12 and the upper mold forming block 22 are tightly fitted. At this time, the fixing pin 14 is fully inserted into the positioning hole 24, and the lower forming groove 13 and the upper mold forming groove 23 are closed to form a complete cavity. The copper bar raw material is squeezed and shaped in the cavity, and is formed into an "N" shaped new energy hard copper bar 3 in one step. After the molding is completed, the upper mold 2 is driven to move upward. Under the auxiliary reset action of the spring 17, the upper mold 2 rises smoothly along the trajectory of the positioning rod 16, the mold opens, and finally the molded new energy hard copper bar 3 is taken out, completing the one-step molding process.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
