Description

Technical Field

[0001] This utility model relates to the field of decorative panel processing technology, and in particular to a decorative panel stamping die. Background Technology

[0002] In current decorative panel stamping processes, traditional molds often suffer from insufficient mold-closing precision, easily leading to dimensional errors in the formed panels due to positioning deviations, thus affecting product quality. The demolding stage relies heavily on manual removal, lacking an automatic ejector mechanism, which is not only inefficient but also prone to damaging the formed panels. Furthermore, traditional molds are mostly one-piece designs, requiring complete replacement when parts are damaged, and the connection between the lower mold and the mounting base lacks stability, making disassembly and maintenance inconvenient. These problems restrict the production efficiency and processing consistency of decorative panel stamping, necessitating a high-precision, easy-to-demold, and flexible-assembly stamping die solution.

[0003] The prior art patent document CN221756211U discloses a decorative panel stamping die, including an upper die structure and a lower die structure. The upper die structure is provided with several first upper die punches for punching waist holes; the lower die structure is provided with first lower die slots; the first upper die punches can be individually disassembled from the upper die structure, and the upper ends of the first upper die punches are clamped between an upper pad and an upper clamping plate for positioning; the several first lower die slots can be independently disassembled from the lower die structure, the lower die structure includes a lower template and a lower pad, and the first lower die slots include slots that can be removed from the lower template, and the lower template has slot holes that mate with the slots. This utility model of a decorative panel stamping die designs the easily worn punches and slots in the upper and lower dies as individually detachable structures, so that when a certain part is worn, the corresponding position can be replaced individually, reducing equipment maintenance costs and effectively improving the punching quality of the workpiece.

[0004] Existing technologies design easily worn punches and slots in the upper and lower dies as separately detachable structures, facilitating individual component replacement and reducing maintenance costs. However, in actual use, the multi-segment design of this stamping die results in numerous gaps, easily leading to insufficient splicing accuracy. Furthermore, after stamping, there is a lack of convenient part removal methods, requiring manual removal of the panel from the lower die slot, affecting production efficiency. Therefore, we propose a decorative panel stamping die that solves the problems of insufficient stamping accuracy and inconvenient part removal, improving the ease of use and production quality of this stamping die.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0021] Please see Figures 1-4This utility model provides a technical solution: a decorative panel stamping die, including a stamping table 1, a mounting base 2 fixedly disposed at the top of the stamping table 1, a lower die 3 fixedly disposed at the top of the mounting base 2, trapezoidal grooves 4 formed on the upper surfaces of both ends of the lower die 3, stepped locking blocks 5 fixedly disposed on the bottom sides of both ends of the lower die 3, a stepped locking groove 6 fixedly disposed at the top of the mounting base 2 to match and engage with the stepped locking blocks 5, limit guide posts 7 fixedly disposed on both sides of the mounting base 2, an upper die 8 slidably connected to the outer side of the limit guide posts 7, trapezoidal blocks 13 fixedly disposed on the bottom sides of both ends of the upper die 8 to match and engage with the trapezoidal grooves 4, the upper die 8 includes an upper base plate 14 and an upper template 15, an installation groove 16 formed inside the upper base plate 14, a locking strip 17 fixedly disposed inside the installation groove 16, a strip groove 18 formed on the side of the upper template 15 near the upper base plate 14 to match and engage with the locking strip 17, the locking strip 17 and the upper template 15 are horizontally connected. A number of first fixing screw holes 19 are equally spaced, and first fixing bolts 20 are provided for each first fixing screw hole 19. U-shaped mounting blocks 21 are fixedly installed at both ends of the upper template 15. U-shaped grooves 22 corresponding to the U-shaped mounting blocks 21 are provided inside the mounting groove 16. Second fixing screw holes 23 are provided for the U-shaped mounting blocks 21 and U-shaped grooves 22 respectively. Second fixing bolts 24 are provided for each second fixing screw hole 23. Third fixing screw holes 25 are provided for each step-shaped slot 6 and step-shaped block 5 respectively. Third fixing bolts 26 are provided for each third fixing screw hole 25. A side plate 27 is fixedly installed on one side of the stamping table 1. A top plate 28 is fixedly installed on the top of the side plate 27. A hydraulic rod 29 is fixedly installed on the bottom surface of the top plate 28. The bottom end of the hydraulic rod 29 is fixedly connected to the top surface of the upper mold 8. The top of the limiting guide post 7 is fixedly connected to the top and bottom surfaces. A PLC controller 30 is fixedly installed on the side wall of the stamping table 1.

[0022] The PLC controller 30 activates the hydraulic rod 29, causing the upper mold 8 to slide downwards along the limiting guide post 7. The trapezoidal block 13 of the upper mold 8 precisely engages with the trapezoidal groove 4 of the lower mold 3, completing the positioning. The hydraulic rod 29 applies pressure, and the upper template 15 cooperates with the lower mold 3 to stamp the decorative panel. After stamping, the hydraulic rod 29 resets, the upper mold 8 rises, and the formed part is removed. The lower mold 3 is fixed to the stepped groove 6 of the mounting base 2 by the stepped locking block 5, and the upper template 15 is fixed to the upper base plate 14 by the locking strip 17 and the U-shaped mounting block 21 for easy replacement or maintenance later.

[0023] The lower mold 3 has a lower mold groove 9 in the middle. A push rod 10 is movably arranged directly below the lower mold groove 9. A fixing rod 11 is slidably sleeved inside the push rod 10. The fixing rod 11 is fixedly installed on the top surface of the stamping table 1, and a spring 12 is sleeved on the outer side of its lower end. The top of the spring 12 is fixedly connected to the push rod 10.

[0024] After stamping, the upper mold 8 is raised via the hydraulic rod 29. At this time, the compressed spring 12 returns to its original position, pushing the ejector rod 10 to slide upward along the fixed rod 11. The top of the ejector rod 10 extends into the lower mold groove 9, ejecting the formed decorative panel from the lower mold groove 9 for easy removal. The fixed rod 11 ensures that the ejector rod 10 moves vertically, preventing the workpiece from tilting during ejection. This structure, combined with the precise positioning of the upper and lower molds, improves part removal efficiency and operational safety.

[0025] Working principle: First, the panel is placed on the top surface of the lower mold 3. Then, the hydraulic rod 29 is extended by the PLC controller 30. The hydraulic rod 29 drives the upper mold 8 to move down and close with the lower mold 3, thus achieving the panel stamping effect. During the stamping process, the cooperation of the trapezoidal groove 4 and trapezoidal block 13, as well as the limiting action of the limiting guide post 7, ensures the mold closing accuracy. At the same time, as the upper mold 8 extrudes the panel downwards, it simultaneously presses down on the top of the ejector rod 10. The ejector rod 10 slides down along the fixed rod 11, causing the spring 12 to contract and deform. After stamping is completed, the hydraulic rod 29 retracts and resets, driving the upper mold 8 to move upwards synchronously. At this time, the ejector rod 10 is depressurized, causing the spring 12 to reset and extend, pushing the formed panel upwards, making it easier for the operator to remove the panel for the next round of stamping.

[0026] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
