Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 , Figure 3 , Figure 4In one embodiment of this utility model, the base 1 serves as the basic support component of the entire stamping die quick-change device. It is made of high-strength metal material, possessing excellent compressive and deformation resistance, and can stably bear various forces generated during device operation. Positioning rods 2 are fixedly connected to the four corners of the top of the base 1. The positioning rods 2 are made of a high-hardness alloy material, and their vertical setting provides precise positioning guidance for the top plate 3, ensuring stable sliding of the top plate 3 in the vertical direction. The top plate 3 is slidably connected to the upper outer side of the positioning rods 2. The top plate 3 is made of lightweight and high-strength alloy plate, possessing good rigidity and toughness, and can withstand the force transmitted by the power rod 4. The power rod 4 is fixedly connected inside the top plate 3; the power rod 4 is solid. The metal rod is used to transmit power to achieve the stamping action. Its material has good wear resistance and strength. The bottom of the power rod 4 is slidably connected to the connecting rod a5. The connecting rod a5 is made of high-quality steel and its surface is specially treated to reduce the friction when sliding with the power rod 4. The power rod 4 is internally fixedly connected to the fixing plate 11, which plays a role in fixing and supporting, ensuring the stability of the connecting rod b12. The connecting rod b12, which is fixedly connected to the bottom of the fixing plate 11, works with the externally slidably connected spring b13 to play a buffering and shock absorption role during the stamping process. The limiting body 14 at the bottom of the connecting rod b12 is connected to the sealing gasket 15. The sealing gasket 15 is made of rubber, which can effectively prevent dust and impurities from entering the device and ensure the stable operation of the device.

[0026] Reference Figure 2 , Figure 5 , Figure 6The bottom of the connecting rod a5 is fixedly connected to a stamping template 6. The stamping template 6 is made of wear-resistant alloy steel, and its working surface is finely ground to ensure the flatness and smoothness of the stamped parts. It is suitable for stamping operations of various materials. A limit ring 7 is fixedly connected to the upper part of the power rod 4. The limit ring 7 is made of high-strength metal and is firmly installed on the power rod 4. It can limit the stroke of the power rod 4 to prevent it from rising excessively and leaving the working area. A convex ring 8 is fixedly connected to the middle of the outside of the power rod 4. The convex ring 8 is integrally formed by forging process and can provide a positioning reference and sliding limit for the sliding sleeve 16 to ensure the stability of the device operation. The sliding sleeve 16 is slidably connected to the outside of the power rod 4. The sliding sleeve 16 is made of alloy material with good self-lubricating properties to reduce friction loss between it and the power rod 4. The outside of the sliding sleeve 16 is provided with anti-slip grooves. 17. The anti-slip groove 17 is machined by milling and its surface is treated with anti-slip material, which makes it easy for the operator to manually and quickly adjust the position of the sliding sleeve 16 to control the stamping action. The top of the base 1 is provided with a positioning groove 18, which is formed by high-precision machining and is used to accurately place the pad 21. Four positioning blocks 19 are fixedly connected to the four sides inside the positioning groove 18. The positioning blocks 19 are made of high-hardness metal and play a role in accurate positioning. The pad 21 is slidably connected inside the positioning groove 18. The pad 21 is made of high-strength and wear-resistant composite material. Four limiting grooves 22 are provided at the bottom. The limiting grooves 22 cooperate with the positioning blocks 19 to realize the quick positioning and installation of the pad 21. The top of the pad 21 is provided with a clearance groove 23, which reserves space for the stamping action of the stamping template 6 to ensure the smooth operation of the stamping operation.

[0027] Refer to 1 to Figure 4The top plate 3 has positioning holes 27 at each of its four corners. These holes 27 are precision machined, with finely polished inner walls to ensure accurate sliding fit with the positioning rods 2. The positioning rods 2 are slidably connected inside the positioning holes 27. The positioning rods 2 are made of high-strength alloy material with a hardened surface to enhance wear resistance and corrosion resistance, ensuring long-term stable operation. A movable plate 20 is fixedly connected to the outer center of the positioning rods 2. The movable plate 20 is made of lightweight and high-strength alloy plate, possessing good rigidity and playing a crucial role in the operation of the device. For stable support and guidance, the four corners of the bottom of the movable plate 20 are fixedly connected with shims b26. The shims b26 are made of highly elastic rubber material, which can effectively buffer the impact force between the movable plate 20 and the base 1, reducing vibration and noise. The lower part of the positioning rod 2 is slidably connected with a spring c25. The spring c25 is made of high-elasticity spring steel and has undergone a special heat treatment process, which has excellent elasticity and fatigue life. It can provide stable buffering and restoring force during device operation. The bottom of the spring c25 is slidably connected with a shim a24. The shim a24 is made of wear-resistant material. The metal material, with a rust-proof surface treatment, is used to distribute the pressure of spring C25 and protect the surface of base 1 from damage. Its bottom is fixedly connected to base 1. The upper outer side of connecting rod A5 has several holes with sliding limit beads 9. The limit beads 9 are made of high-hardness ceramic material, which has the characteristics of low friction coefficient and can slide flexibly in the holes to realize the limiting and guiding function of connecting rod A5. A spring A10 is fixedly connected to the middle of the outer side of connecting rod A5. Spring A10 is made of high-quality spring steel wire and has good elastic recovery performance. The top is slidably connected to the bottom of the sliding sleeve 16 to provide elastic support and restoring force for the sliding sleeve 16. The external part of the positioning rod 2 is slidably connected to the inside of the positioning hole 27. The top edge of the positioning rod 2 is designed with a smooth chamfer to effectively prevent scratching the operator or damaging the parts when installing the top plate 3. The bottom of the positioning hole 27 is fixedly connected to the top of the base 1, and its top edge is also designed with a smooth chamfer to further improve the convenience and safety of assembly, so that the top plate 3 can be smoothly slid along the positioning rod 2 and ensure the assembly accuracy and operational stability of the entire device.

[0028] Working principle: The operator places the stamping die to be replaced in the positioning groove 18 of the base 1. Initial positioning is achieved through the sliding cooperation of the four positioning blocks 19 on the four sides of the positioning groove 18 with the limiting groove 22 at the bottom of the die. Pulling the sliding sleeve 16 upward compresses the spring a10, releasing the constraint of the limiting bead 9 on the outside of the connecting rod a5. After aligning the stamping template 6 with the bottom of the power rod 4, the sliding sleeve 16 is released, the spring a10 returns to its original position, pushing the sliding sleeve 16 downward. The limiting bead 9 engages with the corresponding groove on the inner wall of the power rod 4, completing the quick installation of the stamping template 6. The top plate 3 slides down along the positioning rod 2 through the four corner positioning holes 27. The smooth chamfer design at the top of the positioning rod 2 facilitates quick alignment and insertion. The external power device drives the power rod 4 downward. The limiting ring 7 on the outside of the power rod 4 limits the maximum stroke of the sliding sleeve 16. During the downward movement of the power rod 4, the convex ring 8 first contacts the sliding cavity inside the connecting rod a5, driving the connecting rod a5 and the stamping template 6 downward synchronously. The spring c25 on the outside of the positioning rod 2 is compressed by the movable plate 20, providing buffering force and ensuring... To ensure stability during the stamping process, the sliding engagement between the limiting groove 22 at the bottom of the pad 21 and the positioning block 19 prevents the mold from shifting during stamping. The power rod 4 continues to descend, and the stamping template 6 contacts the workpiece to begin the stamping operation. The spring b13 provides buffering for the stamping process through the connecting rod b12 and the limiting body 14, avoiding excessive impact force that could damage the mold. The sealing gasket 15 prevents debris generated during the stamping process from entering the equipment, improving the equipment's service life. The clearance groove 23 provides space for material deformation during the stamping process, ensuring processing accuracy. Pulling the sliding sleeve 16 upward compresses the spring a10, releasing the limiting bead 9 from the constraint of the power rod 4, allowing the stamping template 6 to be quickly removed. The external power device drives the power rod 4 upward to the initial position, and the spring c25 pushes the movable plate 20 to reset. The smooth chamfer design on the outside of the positioning rod 2 facilitates the quick disassembly of the top plate 3 along the positioning rod 2. The pad 21 can be quickly removed from the positioning groove 18 through the sliding engagement between the limiting groove 22 and the positioning block 19, completing the overall disassembly of the mold.

[0029] The anti-slip groove 17 increases the external friction of the sliding sleeve 16, making it easier for operators to grip and operate during mold changes. The shims a24 and b26 limit and buffer the upper and lower ends of the spring c25, respectively, extending the service life of the spring. The fixing plate 11 inside the power rod 4 provides stable support for the connecting rod b12, ensuring the reliable operation of the buffer mechanism. Through the sliding fit between the positioning rod 2 and the positioning hole 27, and the elastic return of the spring a10, this device realizes the rapid replacement and precise positioning of stamping dies, significantly improving the production efficiency of stamping operations and the convenience of mold replacement.
