[0026] The lower mold 2 is fixedly installed on the top of the stamping base 1 and is located between the opposite sides of the two fixed boxes 301 to ensure the stability of the installation of the lower mold 2. At the same time, the size of the internal mold cavity of the lower mold 2 can be easily adjusted.

[0027] It should be noted that the driving assembly 309 includes a servo motor 3091 fixedly mounted on the opposite side wall of the inner cavity of the two fixed boxes 301, the output shafts of the two servo motors 3091 are fixedly mounted with a rotating shaft 3092, and the outer sides of the two rotating shafts 3092 are provided with a rod wheel assembly 3093.

[0028] Among them, the opposite sides of the two rotating shafts 3092 are rotatably connected to the opposite side walls of the inner cavities of the two fixed boxes 301 to ensure the stability of the rotation of the two rotating shafts 3092. When the two servo motors 3091 are started at the same time, the two servo motors 3091 will drive the two rotating shafts 3092 to rotate respectively.

[0029] In addition, the rod-wheel assembly 3093 includes a worm fixedly mounted on the outside of the two rotating shafts 3092, and a worm wheel meshing with the worm is fixedly mounted on the outside of the two rotating rods 306. When the two rotating shafts 3092 rotate, the two rotating shafts 3092 will respectively drive the two worms to rotate, and the two worms will respectively drive the two worm wheels meshing with them to rotate, and the two worm wheels will respectively drive the two rotating rods 306 to rotate.

[0030] It should be noted that the support assembly 307 includes a support plate fixedly installed on the opposite sides of the two fixed boxes 301, and the two rotating rods 306 are respectively rotatably connected to the inside of the two support plates. The two supporting plates can respectively provide stable support for the two rotating rods 306 to ensure the stability of the rotation of the two rotating rods 306.

[0031] In addition, the bevel gear assembly 308 includes an active bevel gear fixedly mounted on the back of the two rotating rods 306, and the outer sides of the two threaded sleeves 302 are fixedly mounted with driven bevel gears meshing with the active bevel gear.

[0032] It should be noted that the two limit rods 305 on the left and right sides can limit the two adjustment plates 304 respectively, thereby avoiding the rotation of the adjustment plates 304, and the two adjustment plates 304 can prevent the two threaded rods 303 from rotating respectively. Therefore, when the two threaded sleeves 302 rotate, under the action of the thread thrust, the two threaded sleeves 302 will respectively drive the two threaded rods 303 to move to the opposite side or the opposite side, and the two threaded rods 303 will respectively drive the two adjustment plates 304 to move to the opposite side or the opposite side.

[0033] Among them, because the two adjustment plates 304 are slidably connected to the inside of the lower mold 2, when the two adjustment plates 304 move to the opposite side or the back side, the distance between the opposite sides of the two adjustment plates 304 can be adjusted. By adjusting the distance between the opposite sides of the two adjustment plates 304, the size of the internal mold cavity of the lower mold 2 can be adjusted, which is convenient for stamping workpieces of different sizes and increases the efficiency of workpiece stamping.

[0034] In addition, the two servo motors 3091 can be started or notified simultaneously, and can also be started separately or simultaneously, so that asymmetric workpieces can be stamped.

[0036] The working principle of the above embodiment is:

[0037] When the stamping die with a variable cavity is in use, two servo motors 3091 are started at the same time, and the two servo motors 3091 will respectively drive the two rotating shafts 3092 to rotate, and the two rotating shafts 3092 will respectively drive the two worms to rotate, and the two worms will respectively drive the two worm wheels meshing therewith to rotate, and the two worm wheels will respectively drive the two rotating rods 306 to rotate, and the two rotating rods 306 will respectively drive the two active bevel gears to rotate, and the two active bevel gears will respectively drive the two driven bevel gears meshing therewith to rotate, and the two driven bevel gears will The two threaded sleeves 302 are driven to rotate respectively. Under the action of thread thrust, the two threaded sleeves 302 will respectively drive the two threaded rods 303 to move to the opposite side or the opposite side, and the two threaded rods 303 will respectively drive the two adjustment plates 304 to move to the opposite side or the opposite side, so that the distance between the opposite sides of the two adjustment plates 304 can be adjusted. By adjusting the distance between the opposite sides of the two adjustment plates 304, the size of the internal cavity of the lower mold 2 can be adjusted, which is convenient for stamping workpieces of different sizes and improves the efficiency of workpiece stamping.
