[0027] In the embodiments of this utility model, please refer to Figure 2 and Figure 3The pushing structure 3 includes two fixed plates 302, two fixed blocks 301, and two positioning blocks 312. The two fixed plates 302 are fixedly connected to the punching machine 1, the two fixed blocks 301 are fixedly connected to the punching machine 1, and the two positioning blocks 312 are fixedly connected to the punching machine 1. A motor 307 is fixedly connected to the side of the fixed block 301 away from the punching machine 1. A limit groove 303 is opened on the inner wall of the fixed plate 302. A moving block 306 is slidably connected to the inner wall of the limit groove 303. A lead screw 304 is rotatably connected to the inner wall of the limit groove 303. The lead screw 304 is rotatably connected to the fixed plate 302 and fixedly connected to the output end of the motor 307. A connecting plate 308 is fixedly connected to the side of the moving block 306 away from the punching machine 1. A push plate 310 is fixedly connected to the side of the two connecting plates 308 away from the positioning blocks 312. A positioning rod 309 is slidably connected to the inner wall of the positioning block 312. The two positioning rods 309 are fixedly connected to the push plate 310. When personnel need to push the mold body 2 onto the mold transfer arm 5, they can activate two motors 307 to move the push plate 310 towards the mold transfer arm 5 until the mold body 2 is on the mold transfer arm 5. This allows for quick and easy replacement of the mold body 2, improving work efficiency. Two limiting rods 305 are fixedly connected to the inner wall of the limiting groove 303, and these rods 305 are slidably connected to the moving block 306. The limiting rods 305 limit the moving block 306, preventing misalignment during sliding along the inner wall of the limiting groove 303. A protective pad 311 with a rectangular cross-section is fixedly connected to the side of the push plate 310 away from the connecting plate 308. The protective pad 311 protects both the push plate 310 and the mold body 2, preventing direct contact between them. The connecting plate 308 is made of stainless steel. Stainless steel plates have high strength and good wear resistance, which can prevent deformation of the 308 connecting plate during short-term use. In the embodiments of this utility model, please refer to Figures 4 to 6The auxiliary structure 4 includes a fixed frame 403 and a mounting block 401. The fixed frame 403 is fixedly connected to the mold moving arm 5, and the mounting block 401 is fixedly connected to the punching machine 1. A connecting rod 404 is fixedly connected to the inner wall of the fixed frame 403. A threaded rod 405 is rotatably connected to the arc surface of the connecting rod 404. A positioning hole 402 is opened on the inner wall of the mounting block 401. A limit post 409 is slidably connected to the inner wall of the positioning hole 402. A fixed rod 408 is fixedly connected to the end of the limit post 409 away from the punching machine 1. The fixed rod 408 is slidably connected to the threaded rod 405. A rotating ring 406 is threadedly connected to the arc surface of the threaded rod 405. The rotating ring 406 is rotatably connected to the fixed rod 408. When personnel need to move the mold body 2 onto the mold transfer arm 5, they can rotate the fixed rod 408 and the rotating ring 406 to allow the limiting post 409 to slide into the inner wall of the positioning hole 402, thereby improving the stability of the mold transfer arm 5. The rotating ring 406 has several anti-slip grooves 407 evenly distributed on its arc surface. These grooves increase the friction between the personnel's hands and the rotating ring 406, preventing slippage during rotation. A guide block 410 is fixedly connected to the side of the limiting post 409 away from the fixed rod 408, and this guide block 410 is slidably connected to the positioning hole 402. The guide block 410 guides the limiting post 409, facilitating its sliding into the inner wall of the positioning hole 402. The working principle of the mold pushing mechanism of the quick mold changing system provided by this utility model is as follows: When personnel need to change the mold body 2, they can first operate the electronic controller 7 to move the four first mold clamps 8 and the four second mold clamps 9 away from the mold body 2. Then, the personnel can start the mold lifting device 6 to move the mold body 2 upward. At this time, the personnel can start the two motors 307. The output end of the motors 307 drives the lead screw 304 to rotate. The lead screw 304 drives the moving block 306 to move away from the motor 307. The moving block 306 slides on the arc surface of the two limit rods 305. The limit rods 305 can limit the moving block 306 and prevent the moving block 306 from being misaligned during the sliding process on the inner wall of the limit groove 303. Then, the moving block 306 drives the connecting plate 308 away from the motor 307. The motor 307 moves in the direction of movement. The connecting plate 308 is made of stainless steel, which has high strength and good wear resistance, preventing deformation of the connecting plate 308 during short-term use. Then, the two connecting plates 308 drive the support plate to move away from the positioning block 312. The push plate 310 drives the protective pad 311 and the two positioning rods 309 to move closer to the mold body 2. The protective pad 311 protects the push plate 310 and the mold body 2, preventing direct contact between the push plate 310 and the mold body 2 until the protective pad 311 abuts against the mold body 2. Then, the protective pad 311 drives the mold body 2 to move closer to the mold moving arm 5. The mold body 2 slides on the surface of the two mold lifting devices 6 until the mold body 2 moves to the upper surface of the two mold moving arms 5.

[0028] Additionally, when personnel need to move the mold body 2 onto the mold transfer arm 5 for mold changing, they can first rotate the fixing rod 408, causing it to move closer to the mounting block 401. The fixing rod 408 then drives the limiting post 409, the rotating ring 406, and the threaded rod 405 to rotate closer to the mounting block 401. The limiting post 409 then drives the guide block 410 to rotate closer to the positioning hole 402 until the guide block 410 aligns with the positioning hole 402. The guide block 410 can... The limiting post 409 serves as a guide, allowing personnel to easily slide the limiting post 409 into the inner wall of the positioning hole 402. Then, the personnel rotate the rotating ring 406, which drives the fixed rod 408 to move closer to the positioning hole 402 until the guide block 410 and the limiting post 409 slide into the inner wall of the positioning hole 402. The anti-slip groove 407 on the arc surface of the rotating ring 406 increases the friction between the personnel's hands and the rotating ring 406, preventing the personnel from slipping during the rotation of the rotating ring 406.

[0029] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
