[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0025] Example:

[0026] As attached Figure 1 To be continued Figure 6 As shown:

[0027] This utility model provides an adjustable stamping die, including a base 1, a pressure cover 2, a motor 3, a rear plate frame 5, a shifting motor 7, a slide rail 8, a threaded rod 201, a double connector 301, a rotating shaft sleeve 302, and a movable seat 602. The bottom two sides of the shifting motor 7 are fastened to the top of one side of the base 1 by screws, and a long screw 701 is fastened to the rotating shaft on one side of the shifting motor 7. The long screw 701 is rotatably connected to the circular holes on both sides of the slide rail 8. The bottom of the movable seat 602 is movably connected to the square track groove on the upper part of the slide rail 8, and the circular hole at the bottom of the movable seat 602 is connected to the long screw 701. 1. A limit rod 601 is fastened to the circular holes at the four corners of the movable seat 602. The pressure cover 2 is movably connected to the upper part of the limit rod 601 through the circular through holes at the four corners. A threaded rod 201 is rotatably connected to the circular groove at the top of the pressure cover 2. Two sets of hydraulic devices 4 are fastened to the lower part of the upper part of the rear plate frame 5 by screws. Hydraulic rods 401 are telescopically connected inside the hydraulic devices 4. Square plates on both sides of the motor 3 are fastened to the bottom of the hydraulic rods 401. A double connector 301 is fastened to the bottom shaft of the motor 3. A shaft sleeve 302 is fastened to the other side of the double connector 301.

[0028] The base 1 has threaded holes on both sides of its top, and the slide rail 8 is fastened to the threaded holes on both sides of its bottom by screws. Each side of the slide rail 8 has a set of square slots. The threaded holes and screws can firmly fix the slide rail 8 and prevent it from shifting during stamping. The square slots can accommodate the end structure of the long screw 701, providing space for the long screw 701 to rotate and ensuring smooth adjustment of the moving seat 602.

[0029] The movable seat 602 has a square groove on its top, and a plastic mold 6 is fitted into the square groove on the top of the movable seat 602. The pressure cover 2 has a set of square grooves on its bottom, and the square grooves on the bottom of the pressure cover 2 correspond to the top of the plastic mold 6. The square groove fitting structure allows for quick assembly and disassembly of the plastic mold 6 to meet the needs of multi-shape processing. The corresponding position design allows the pressure cover 2 to accurately press the plastic mold 6, ensuring the forming accuracy of the stamped workpiece.

[0030] The threaded rod 201 has a thread on its outer side, and the rotating sleeve 302 has a threaded hole on its inner side. The internal thread of the rotating sleeve 302 is rotatably connected to the external thread of the threaded rod 201. This threaded engagement can convert the rotational power of the motor 3 into the linear motion of the cover 2, thereby realizing the lifting and lowering of the cover 2. At the same time, the precision of the threaded transmission can control the pressing force and stroke of the cover 2, ensuring the stamping accuracy.

[0031] The top of one side of the base 1 is welded to the bottom of the rear plate frame 5. The welded connection can ensure the stability of the rear plate frame 5 and the base 1 and withstand the longitudinal force during stamping. At the same time, it forms an overall frame structure, providing stable support for components such as the hydraulic device 4 and the motor 3, and ensuring the structural rigidity of the equipment during operation.

[0032] The base 1 has a set of square through holes on its inner side. These square through holes can reduce the amount of material used in the base 1 itself while maintaining the load-bearing strength of the base 1 and ensuring the stamping stability, thus achieving a lightweight device. The lightweight design can reduce the overall weight of the mold, making it easier to move and install the equipment and adapt it to the stamping machine, thereby reducing the energy consumption of the equipment.

[0033] The specific usage and function of this embodiment are as follows:

[0034] In this invention, the plastic mold 6 is mounted in the square groove at the top of the movable seat 602. The shifting motor 7 is started, and its shaft drives the long screw 701 to rotate in the circular holes on both sides of the slide rail 8, so that the movable seat 602 moves along the square track groove at the top of the slide rail 8 to the designated processing position. Then, the hydraulic device 4 on the upper part of the rear plate frame 5 is started. The hydraulic device 4 drives the hydraulic rod 401 to extend and retract, driving the motor 3 to descend, so that the rotating sleeve 302 is connected with the threaded rod 201 at the top of the pressure cover 2. The motor 3 is started, and its shaft drives the rotating sleeve 302 to rotate through the double connector 301. With the threaded transmission of the threaded rod 201, the pressure cover 2 descends smoothly along the limiting rod 601 until the square groove at the bottom of the pressure cover 2 fits with the plastic mold 6 to complete the stamping. When processing workpieces of different shapes, the plastic mold 6 on the movable seat 602 can be directly removed and replaced. The square through hole on the inner side of the base 1 can help to discharge processing waste. The whole process realizes efficient and precise stamping of workpieces of various specifications.
