[0002] Motor mold is a kind of equipment used to manufacture motors. In order to reduce the mold opening cost, it is an effective way to use a set of molds to process as many types of products as possible. In order to achieve the above purpose, more and more multi-punch motor molds are used in production.

[0003] The Chinese utility model patent with announcement number CN207414144U proposes a multi-punch motor mold, including a mold body, the mold body is provided with a mounting groove, a height adjustment plate is provided in the mounting groove, the height adjustment plate is provided with multiple height adjustment grooves of different depths and multiple punches, the bottom of the height adjustment groove is provided with a screw hole, the punch is fixed in the screw hole by a thread, and adjacent screw holes are connected together by a groove, and the width of the groove is less than the diameter of the screw hole.

[0004] Although the above device can adjust the height of the punch to adapt to the processing of different motor molds, it has two shortcomings in its structural design;

[0005] The punch is constructed with threads. Frequent installation, disassembly and cleaning will damage the thread structure. After a period of use, the threads will slip, resulting in a loose connection of the punch. This structural design not only increases the difficulty of maintenance, but may also affect production efficiency and product quality.

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0027] The present application provides a multi-punch motor mold, which is mainly used to solve the problem that the punch is constructed with threads in the prior art. Frequent installation, disassembly and cleaning will damage the thread structure. After a period of use, the thread will slip, resulting in a loose connection of the punch. This structural design not only increases the difficulty of maintenance, but also may affect production efficiency and product quality. The following technical solutions are provided. Figure 1-Figure 3 Give detailed instructions:

[0028] A multi-punch motor die, comprising:

[0029] The installation box 1 has an open front and a strip-shaped channel 101 in the middle of its bottom;

[0030] The step block 2 is in a stepped shape and is symmetrically fixed on both sides of the strip channel 101;

[0031] The die punch 3 is arranged at the bottom of the mounting box 1. An extension rod 4 is fixed to the top of the die punch 3. The other end of the extension rod 4 passes through the strip-shaped channel 101 and is connected to a kidney-shaped plate 5. The width of the kidney-shaped plate 5 is smaller than the width of the strip-shaped channel 101. The two ends of the kidney-shaped plate 5 are placed in the middle of each step of the step block 2.

[0032] The locking members 6 are arranged at equal intervals on the top of the installation box 1 , and are used to clamp and fix the kidney-shaped plate 5 .

[0033] It should be noted that the size of the kidney-shaped plate 5 and the extension rod 4 in this device is fixed, but the size of the die punch 3 is not fixed.

[0034] Workflow Description:

[0035] Before you start using this multi-punch motor die, make sure all components are intact;

[0036] Place the die punch 3 at the bottom of the mounting box 1 so that the extension rod 4 passes through the strip-shaped channel 101. Adjust the position of the kidney-shaped plate 5 according to the type of motor die to be processed. Move the kidney-shaped plate 5 so that its two ends are placed in the middle of a step of the step block 2 to adjust the height of the die punch 3.

[0037] The locking member 6 is used to clamp and fix the kidney-shaped plate 5. After confirming that the position and height of the die punch 3 have been adjusted and fixed, the processing of the motor die is started.

[0038] The multi-punch motor mold fixes the punch by a locking piece 6, and a threadless connection is adopted between the punch and the mounting box 1, which makes installation and disassembly simpler. At the same time, it avoids the damage to the thread structure and the slipping phenomenon caused by frequent installation and disassembly and cleaning, and extends the service life of the equipment. In addition, the adjustment of the mold punch 3 is mainly achieved by the step block 2. The height of the kidney-shaped plate 5 is changed by the step block 2, and then the height of the mold punch 3 at the bottom of the extension rod 4 is changed. This installation method has fewer restrictions on the specifications of the mold punch 3, thereby improving the applicability of the motor mold.

[0039] like Figure 1 As shown, in some embodiments, an arc-shaped groove 201 is constructed in the middle of one side of each step of the step block 2 close to the rectangular channel, and the two ends of the kidney-shaped plate 5 are embedded in the inside of the arc-shaped groove 201. More specifically, by embedding the two ends of the kidney-shaped plate 5 in the arc-shaped groove 201, the shaking of the mold punch 3 during the processing can be effectively reduced. The design of the arc-shaped groove 201 plays a positioning role, and at the same time makes the kidney-shaped plate 5 more firmly fixed on the step block 2.

[0040] like Figure 1 As shown, in some embodiments, the locking member 6 includes a fixing nut 601 embedded in the bottom of the mounting box 1, and the internal thread of the fixing nut 601 is connected to a locking bolt 602, and the locking bolt 602 is located directly above the kidney-shaped plate 5. More specifically, by rotating the locking bolt 602 so that its bottom end contacts the kidney-shaped plate 5, the kidney-shaped plate 5 can be fixed, ensuring that the mold punch 3 will not shake or shift during the processing, which helps to improve processing accuracy and reduce errors.

[0041] like Figure 1 As shown, in some embodiments, a rotating disk 603 is fixed to the top of the locking bolt 602, and the side of the rotating disk 603 is configured with anti-slip grooves. More specifically, the design of the rotating disk 603 simplifies the operation process and reduces operation time. The operator only needs to simply hold the rotating disk 603 and rotate it to complete the rotation of the locking bolt 602, thereby improving overall operational efficiency. The presence of the anti-slip grooves increases the friction between the rotating disk 603 and the operator's hand. This helps prevent slipping during rotation and ensures stable and accurate operation.

[0042] like Figure 1 As shown, in some embodiments, a positioning groove 501 is constructed in the middle of the top of the kidney-shaped plate 5, and the positioning groove 501 is adapted to the size of the locking bolt 602. More specifically, the close fit between the positioning groove 501 and the locking bolt 602 makes the entire mold system more stable and reliable. During the processing, the mold punch 3 will not shake or shift due to external force, thereby ensuring the processing quality and safety.

[0043] like Figure 1 As shown, in some embodiments, a mounting plate 7 is fixedly provided on the top rear side of the mounting box 1, and a mounting hole 701 is constructed on the surface of the mounting plate 7, and a trapezoidal plate is connected between its two sides and the bottom top of the mounting box 1. More specifically, the motor mold can be mounted on a stamping device that applies pressure through the mounting plate 7. The presence of the mounting hole 701 ensures the precise positioning of the mounting plate 7 on the stamping device. By matching with the fixed point on the stamping device, the accurate installation and adjustment of the mold system can be quickly achieved.

[0044] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
