[0051] The following is a further detailed description of this application in conjunction with the attached Figure 1 - 18 drawings.

[0052] The terms used in this application are only for the purpose of describing specific embodiments and are not intended to limit this application. Unless otherwise defined, the technical terms or scientific terms used in this application should have the ordinary meaning understood by those skilled in the art to which this application belongs. The "first", "second" and similar terms used in this application do not indicate any order, quantity or importance, but are only used to distinguish different components.

[0053] This embodiment discloses a forming mold. Referring to Figure 3 the drawings, the forming mold includes two main parts, a fixed mold 2 and a movable mold 3. Through the precise cooperation between these two parts, a series of forming processes of metal terminals from raw materials to finished products are realized.

[0054] Referring to Figure 3 and Figure 4, a first punching mechanism 4, a second punching mechanism 5, a chamfering mechanism 10, a wire clamping groove forming mechanism 6, a partition groove forming mechanism 7, a bending mechanism 8, and a cylindrical forming mechanism 9 are sequentially arranged between the fixed mold 2 and the movable mold 3. The first punching mechanism 4 is used to punch the strip, the second punching mechanism 5 is used to form a grid groove 13 on the strip, the chamfering mechanism 10 is used to chamfer the product 1, the wire clamping groove forming mechanism 6 is used to form a wire clamping groove 12 on the strip, the partition groove forming mechanism 7 is used to form a plurality of first partition grooves 14 and second partition grooves 15 with different shapes on the strip. The first partition grooves 14 and the second partition grooves 15 are located between two adjacent products 1. The bending mechanism 8 is used to bend the edge of the product 1, and the cylindrical forming mechanism 9 is used to form the product 1 into a cylindrical shape. These mechanisms operate on the metal strip in a specific order and manner during the mold closing process, and finally obtain a product that meets the preset shape.

[0055] Referring to Figure 3 and Figure 5 , first of all, the first punching mechanism 4 includes a first punch 41 and a corresponding first punching groove 42. The first punch 41 is fixed on the movable mold 3, and the first punching groove 42 is opened on the fixed mold 2. The first punch 41 is inserted and matched with the first punching groove 42. The number of the first punching mechanisms 4 can be one or more, and the shapes of each first punch 41 and the first punching groove 42 are different, which are used to punch holes with different shapes on the strip. When the mold is closed, the first punch 41 moves downward under the drive of power and is accurately docked with the first punching groove 42, so as to punch the preset hole positions on the strip. Multiple first punching mechanisms 4 with different shapes can operate on the strip at the same time, greatly improving the punching efficiency and flexibility.

[0056] Referring to Figure 5 and Figure 6 , following closely is the second punching mechanism 5. The second punching mechanism 5 includes a plurality of second punches 51 of the second punching mechanism and second punching grooves 52 of the second punching mechanism. The plurality of second punches 51 of the second punching mechanism are fixed on the movable mold 3, and the second punching grooves 52 of the second punching mechanism are opened on the fixed mold 2. The shapes and distribution positions of these punches and punching grooves are carefully designed to ensure that a plurality of grid grooves 13 are accurately formed on the strip (combined with Figure 1 ), and the specific grid groove 13 is a strip-shaped groove, and both ends of the strip-shaped groove are provided with rounded corners. The formation of the grid groove 13 not only enhances the structural strength of the product, but also helps to improve its stability and reliability in actual use.

[0057] Referring to Figure 3, Immediately afterwards, the clamping groove forming mechanism 6 includes a plurality of third punches and third grooves. The plurality of third punches are fixed on the moving die 3, and the plurality of third grooves are formed on the fixed die 2. They work together when the mold is closed to accurately form the clamping grooves 12 on the strip. The clamping grooves 12 further enhance the aesthetics of the product 1.

[0058] Refer to Figure 4 , Next is the partition groove forming mechanism 7, which includes a first groove forming component 71 and a second groove forming component 72. The first groove forming component 71 is used to form the first partition groove 14 on the strip, and the second groove forming component 72 is used to form the second partition groove 15 on the strip.

[0059] Refer to Figure 9 and Figure 10 , The first groove forming component 71 includes a first pressing block 711 and a first groove 712. The first pressing block 711 is fixed on the moving die 3, and the first groove 712 is formed on the fixed die 2. The first pressing block 711 is inserted and matched with the first groove 712. The shapes of both the first pressing block 711 and the first groove 712 are adapted to the shape of the first partition groove 14. During the mold closing process, the first pressing block 711 descends and cooperates with the first groove 712 to accurately press out the shape of the first partition groove 14 on the strip.

[0060] Refer to Figure 11 and Figure 12 , The second groove forming component 72 includes a second pressing block 721 and a second groove 722. The second groove 722 is arranged on the moving die 3, and the second groove 722 is formed on the fixed die 2. The second pressing block 721 is inserted and matched with the second groove 722; the shapes of both the second pressing block 721 and the second groove 722 are adapted to the shape of the second partition groove 15. The formation of these two partition grooves not only facilitates the separation of two adjacent products 1 but also provides a necessary structural basis for the subsequent cylinder forming.

[0061] Refer to Figure 1 , After the partition grooves are formed, the bending mechanism 8 starts to bend the edges of the product 1. The bending mechanism 8 includes an angle bending component 81 and a fillet bending component 82. The angle bending component 81 is used to bend the edges of the flat product 1, thereby machining a bent portion on the edges of the product 1. The bent portion is not in the same plane as the product 1. The fillet bending component 82 is used to process the bent portion from a flat shape into an arc shape. They cooperate with each other when the mold is closed to bend the edges of the product 1 into a preset angle.

[0062] Refer to Figure 13 and Figure 14, the angle bending component 81 includes a first bending block 811 and a second bending block 812. The first bending block 811 is fixed to the fixed mold 2, and the second bending block 812 is fixed to the moving mold 3. When the mold is closed, it drives the second bending block 812 to move towards the direction close to the first bending block 811, so as to realize the bending of the edge of the product 1. Through the cooperation of the first bending block 811 and the second bending block 812, the angle bending component 81 can accurately bend the edge of the product when the mold is closed, improving the Figure 1 and Figure 2 forming accuracy and stability of the product 1 (combined with

[0063] Refer to Figure 15 and Figure 16 , the fillet bending component 82 includes a first forming block 821 and a second forming block 822. The first forming block 821 is fixed to the fixed mold 2, and an arc-shaped groove 823 is formed on the first forming block 821. The second forming block 822 is fixed to the moving mold 3, and an arc-shaped convex block 824 is fixedly arranged on the second forming block 822, and a fillet is arranged on the edge of the arc-shaped convex block 824. When the mold is closed, it drives the second forming block 822 to move towards the direction close to the second bending block 812, so as to realize the processing of the edge of the product 1 into an arc shape. Through the cooperation of the first forming block 821 and the second forming block 822, the fillet bending component 82 can process the bending part of the product into an arc shape when the mold is closed, improving the appearance quality and feel of the product 1.

[0064] Refer to Figure 17 and Figure 18 , the last step is to complete the cylindrical forming of the product 1 by the cylindrical forming mechanism 9. The number of the cylindrical forming mechanisms 9 is multiple, and each cylindrical forming mechanism 9 includes a first pressing block 91 and a second pressing block 92. The first pressing block 91 is fixed to the fixed mold 2, and a semi-circular first forming groove 93 is formed on the top of the first pressing block 91. The second pressing block 92 is fixed to the moving mold 3, and a semi-circular second forming groove 94 is formed on the lower surface of the second pressing block 92. When the mold is closed, they are butted against each other and clamp the product 1 in the middle, and the product 1 undergoes plastic deformation under the action of pressure, finally forming a cylindrical structure. The design of the cylindrical forming mechanism 9 fully considers the structural characteristics and actual use requirements of the product 1, ensuring that the formed product 1 has excellent structural strength and reliability.

[0065] Implementation principle of this embodiment: First, the free end of the strip is passed through between the fixed mold 2 and the moving mold 3. While the feeding mechanism conveys the strip, through multiple mold clamping operations between the fixed mold 2 and the moving mold 3, multiple processes such as punching, grille forming, clamping groove 12 forming, partition groove forming, bending, and cylinder forming are sequentially completed. The close cooperation and coordinated work among various mechanisms during this process are the key to ensuring the accuracy and quality of the product 1. At the same time, the modular design of the mold makes it have good versatility and flexibility, and can adapt to the forming requirements of products with different shapes and sizes.

[0066] The above are all preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
