[0004] Although existing stamping and forming equipment for display box processing has demonstrated many advantages in production, with its integrated design reducing production process connection time and adapting to the processing needs of various materials, it also has significant limitations. The mold changing process is cumbersome, requiring manual disassembly of multiple fixed parts, and the adjustment and positioning are time-consuming, making it impossible to achieve rapid mold changing. Frequent mold changing increases equipment downtime, affecting production continuity and making it difficult to adapt to the flexible production needs of small batches and multiple styles of display boxes, thus restricting the improvement of overall processing efficiency.

A rectangular shell 7 has a drive motor 28 fixedly installed on one side. A lead screw 25 is fixedly installed on the output shaft of the drive motor 28. Moving blocks 22 are threadedly connected to both sides of the outer ring of the lead screw 25. A connecting rod 20 is integrally formed on the upper end of the moving block 22. A T-shaped block 19 is provided at the end of the connecting rod 20 away from the sliding block 16. Limiting components 21 are provided on both sides inside the moving block 22. A fixed seat 12 is provided on the upper end of the base 5. A lower mold 13 is integrally formed on the upper end of the fixed seat 12. T-shaped grooves 18 are opened on both sides inside the fixed seat 12. The T-shaped block 19 is slidably installed inside the T-shaped grooves 18.

[0017] refer to Figures 1 to 2 The limiting component 2 includes a limiting rod 10 and a limiting hole 11. The limiting rod 10 is fixedly installed on both sides of the upper end of the push plate 4. The limiting hole 11 is opened on both sides of the upper end of the housing 9 away from the push cylinder 1. The limiting rod 10 is slidably installed inside the limiting hole 11. The push plate 4 is driven to move up and down reciprocally through the output shaft. The limiting components 2 on both sides of the upper end of the push plate 4 ensure that the push plate 4 slides stably in the vertical direction when it moves, avoids deviation, and ensures stamping accuracy.

[0018] refer to Figures 1 to 3 The push plate 4 has sliding grooves 3 on both sides inside. The sliding block 16 slides on both sides inside the push plate 4 through the sliding grooves 3. Multiple adjustment holes 17 are provided on both sides of the push plate 4 away from the sliding grooves 3. The plug rod 14 is inserted into the adjustment hole 17 through the plug hole 15. When the mold needs to be replaced, the upper mold 8 is replaced by the sliding block 16 and the plug structure. The sliding grooves 3 on both sides inside the push plate 4 provide a moving track for the sliding block 16. The sliding block 16 is fixed by the plug rod 14 in the plug hole 15 and the adjustment hole 17 of the push plate 4. When replacing, the sliding block 16 can be pulled out along the sliding groove 3 by pulling out the plug rod 14. After replacing the new mold, the plug rod 14 is reinserted.

[0019] refer to Figure 4The limiting component 21 includes a limiting rod 26 and a limiting hole 27. The limiting rod 26 is fixedly installed on both sides of the inside of the rectangular shell 7 above the lead screw 25. The limiting hole 27 is opened on both sides of the inside of the moving block 22. The moving block 22 is sleeved on the outer ring of the limiting rod 26 through the limiting hole 27. The limiting component 21 inside the rectangular shell 7 restricts the moving block 22 to translate only in the horizontal direction, preventing it from rotating synchronously with the lead screw 25, and ensuring the accurate positioning of the lower mold 13.

[0020] refer to Figures 4 to 5 The moving block 22 has an internal threaded groove 23 at its center. The lead screw 25 is threadedly connected to the moving block 22 through the internal threaded groove 23. The upper end of the base 5 has a connecting groove 24 at its center. The connecting rod 20 slides inside the connecting groove 24. The rectangular shell 7 is fixedly installed on one side of the support seat 29. The end of the support seat 29 away from the rectangular shell 7 is fixedly installed below the drive motor 28. The drive motor 28 is fixedly installed on one side of the rectangular shell 7 through the support seat 29. Support legs 6 are fixedly installed around the bottom of the base 5. The replacement of the lower mold 13 is achieved by reversing the drive motor 28, causing the moving blocks 22 on both sides to drive the T-shaped blocks out of the T-shaped grooves of the fixed seat 12. After removing the old fixed seat 12, the fixed seat 12 with the new lower mold 13 is placed in place. The drive motor 28 rotates forward to make the T-shaped blocks re-engage in the T-shaped grooves, thus completing the fixing of the lower mold 13. The entire mold changing process does not require disassembling a large number of parts.

[0021] Operating principle and advantages: In conventional stamping, the device uses base 5 as the foundation to support the overall structure. Shells 9 are installed on both sides to fix and support the push cylinder 1. The push cylinder 1 serves as the power source, driving the push plate 4 to reciprocate up and down via its output shaft. Limiting components 2 on both sides of the upper end of the push plate 4 ensure stable vertical sliding during movement, preventing deviation and ensuring stamping accuracy. The bottom of the push plate 4 is connected to the upper mold 8 via sliding blocks 16. When the push plate 4 moves downwards, the upper mold 8 precisely engages with the lower mold 13 on the upper end of the fixed base 12, completing the stamping of the display box blank. The fixing and driving of the lower mold 13 rely on the rectangular shell 7 structure at the bottom of the base 5. The drive motor 28 inside the rectangular shell 7 drives the lead screw 25 to rotate via its output shaft. The moving blocks 22 on both sides of the outer ring of the lead screw 25 engage with the lead screw 25 via internal thread grooves 23, moving horizontally along the lead screw 25 under the action of rotational force. The connecting rod 20 at the upper end of the moving block 22 passes through the connecting groove 24 of the base 5, driving the T-shaped block at the end to move horizontally along the T-shaped groove of the fixed base 12. The upper mold 13 slides within the slot, and the relative approach or distance of the two moving blocks 22 enables rapid clamping or release of the fixed seat 12. Simultaneously, the limiting component 21 within the rectangular shell 7 restricts the moving block 22 to only move horizontally, preventing it from rotating synchronously with the lead screw 25, thus ensuring accurate positioning of the lower mold 13. When mold replacement is required, the upper mold 8 is replaced via the sliding block 16 and the insertion structure. The sliding grooves 3 on both sides inside the push plate 4 provide a moving track for the sliding block 16. The sliding block 16 is fixed by the insertion rod 14 within the insertion hole 15 and the adjustment hole 17 of the push plate 4. During replacement, the insertion rod 14 is pulled out to remove the sliding block 16 along the sliding groove 3. After replacing the mold, the insertion rod 14 is reinserted. Different sizes of upper mold 8 can be adapted by selecting different adjustment holes 17. The replacement of the lower mold 13 is achieved by reversing the drive motor 28, causing the two moving blocks 22 to move the T-shaped block from the fixed seat 12. After exiting the slot and removing the old fixing seat 12, the fixing seat 12 with the new lower mold 13 is placed in place. The drive motor 28 rotates forward to make the T-block re-engage into the T-slot, thus completing the fixing of the lower mold 13. The entire mold changing process does not require disassembling a large number of parts.
