[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, when it is necessary to replace the upper mold, simply move the actuating plate to allow the locking block to overcome the elastic force of the spring and move outward, quickly disengaging from the locking state with the fixing hole, and easily removing the mounting block. When installing the new mold, release the actuating plate, the spring pushes the locking block back to its original position and inserts it into the fixing hole, completing a secure installation.

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0032] Reference Figures 1-3This utility model provides an embodiment of a quick-change structure for stamping dies of automotive parts, including a base plate 1. The base plate 1 serves as the basic load-bearing component of the entire die-changing structure, supporting other components. A lower die 2 is fixedly connected to the top of the base plate 1. The lower die 2 is used to form the lower shape of automotive parts and cooperates with the upper die 8 to complete the stamping work. Two guide rods 3 are fixedly connected to the rear top of the base plate 1. The guide rods 3 provide a guiding path for the sliding of the sliding sleeves 4, ensuring the stability and accuracy of the vertical movement of the mounting plate 5. The sliding sleeves 4 are slidably connected to the outer wall of the guide rods 3. The sliding sleeves 4 can slide up and down along the guide rods 3, thereby driving the mounting plate 5 to move up and down. A mounting plate 5 is fixedly connected between the tops of the two sliding sleeves 4. The mounting plate 5 is used to install the upper die 8 and also serves as the mounting carrier for fixing components. A mounting groove 6 is opened at the bottom of the mounting plate 5, providing a mounting block 7 for mounting. The mounting groove 6 provides space for the upper mold 8 to connect with the mounting plate 5. The inner wall of the mounting groove 6 is equipped with a mounting block 7, which connects the upper mold 8 and the mounting plate 5 to position and fix the upper mold 8 on the mounting plate 5. The bottom of the mounting block 7 is fixedly connected to the upper mold 8, which cooperates with the lower mold 2 to stamp and form automotive parts. The outer wall of the mounting block 7 has two fixing holes 9, which cooperate with the locking block 16 in the fixing assembly to fix the upper mold 8. The inner wall of the mounting plate 5 is provided with a fixing assembly, which is used to fix the mounting block 7 in the mounting groove 6, thereby fixing the upper mold 8 and preventing the upper mold 8 from loosening during the stamping process. The inner wall of the bottom plate 1 is provided with a lifting assembly, which is used to push out the part after stamping for easy removal. The bottom edge of the mounting plate 5 is fixedly connected with a pressure block 10, which is used to apply pressure to the lifting assembly during the stamping process.

[0033] Reference Figures 2-4 The fixing assembly includes two actuating plates 11. The outer wall of the actuating plate 11 is slidably connected to the inner wall of the mounting plate 5. The actuating plate 11 is used to move the locking block 16 by external force, thereby realizing the fixing and disassembly of the upper mold 8. A rope 14 is fixedly connected to the outer wall of the actuating plate 11. The rope 14 is used to transmit the movement of the actuating plate 11, thereby moving the limiting block 15 and the locking block 16. The end of the rope 14 away from the actuating plate 11 is fixedly connected to the limiting block 15. The limiting block 15 is used to limit the range of movement of the rope 14 and at the same time provide a support point for the spring 17. The side of the limiting block 15 away from the rope 14 is fixedly connected to the locking block 16. The locking block 16 is used to insert into the fixing hole 9 to fix the mounting block 7. The outer wall of the rope 14 is fitted with the spring 17. The spring 17 is used to reset the locking block 16 after the external force of the actuating plate 11 is removed, thus ensuring the fixed state of the upper mold 8.

[0034] Reference Figure 5The lifting assembly includes a connecting plate 18, the outer wall of which is slidably connected to the inner wall of the base plate 1. The connecting plate 18 serves as the main connecting component of the lifting assembly, connecting the push rods 19 and the springs 21. Two push rods 19 are fixedly connected to the top of the connecting plate 18. The push rods 19 are used to transmit the movement of the connecting plate 18 to the top block 20, thereby pushing out the part. The top of the push rods 19 is fixedly connected to the top block 20, which directly contacts the stamped part and is used to lift the stamped part. Multiple springs 21 are fixedly connected to the bottom of the connecting plate 18. The springs 21 are used to withstand pressure during the stamping process and provide elasticity during ejection.

[0035] Reference Figures 3-4 Two sliders 12 are fixedly connected to the outer wall of the actuating plate 11. A groove 13 is provided on the inner wall of the mounting plate 5. The outer wall of the slider 12 is slidably connected to the inner wall of the groove 13. The normal operation of the actuating plate 11 is ensured by the sliding of the slider 12 in the groove 13.

[0036] Reference Figure 4 The locking block 16 penetrates the mounting plate 5 and engages with the fixing hole 9. Through the engagement of the locking block 16 with the fixing hole 9, the mounting block 7 is fixed in the mounting groove 6, thereby achieving a stable installation of the upper mold 8.

[0037] Reference Figure 4 One end of spring 17 is fixedly connected to the inner wall of mounting plate 5, and the other end of spring 17 is fixedly connected to the outer wall of limiting block 15. Spring 17 provides elastic force between the inner wall of mounting plate 5 and limiting block 15. When the actuating plate 11 is subjected to external force and the locking block 16 moves, spring 17 can reset the locking block 16 when the external force is removed, ensuring the fixing effect of upper mold 8.

[0038] Reference Figure 2 and Figure 5 The bottom of the pressure block 10 and the top of the connecting plate 18 are attached together. During the stamping process, the pressure block 10 transmits the pressure of the mounting plate 5 to the connecting plate 18. The end of the spring 21 away from the connecting plate 18 is fixedly connected to the inner wall of the bottom plate 1 to ensure that the connecting plate 18 bears the pressure during stamping and assists the lifting and resetting of the top block 20 after stamping.

[0039] Reference Figure 2 and Figure 5 The length of the pressure block 10 is equal to the thickness of the mounting plate 5, ensuring that the pressure block 10 can evenly transmit the pressure of the mounting plate 5 to the connecting plate 18. The height of the connecting plate 18 is equal to the thickness of the lower mold 2, so that the connecting plate 18 can completely lift the part when it is lifted.

[0040] Reference Figure 5 The outer wall of the top rod 19 is slidably connected to the inner wall of the base plate 1, ensuring that the top rod 19 can slide up and down within the base plate 1, thereby accurately transmitting the movement of the connecting plate 18 to the top block 20.

[0041] Working principle: When stamping is required, pressure is applied to the mounting plate 5 by the stamping press, causing the mounting plate 5 to slide on the outer wall of the guide rod 3 via the sliding sleeve 4. This causes the upper die 8 and the lower die 2 to gradually approach each other and complete the stamping action. During this process, the pressure block 10 is in contact with the top of the connecting plate 18, transmitting the pressure of the mounting plate 5 to the connecting plate 18. The spring 21 at the bottom of the connecting plate 18 is compressed.

[0042] After the stamping is completed, the stamping machine resets. At this time, as the mounting plate 5 moves upward, the pressure of the pressure block 10 on the connecting plate 18 decreases, and the spring 21 gradually recovers its deformation, pushing the connecting plate 18 upward. The connecting plate 18 drives the ejector rod 19 and the ejector block 20 to rise together. The ejector block 20 pushes the stamped part out of the lower mold 2, facilitating the removal of the part and subsequent processing.

[0043] When the upper mold needs to be replaced, the actuating plate 11 is moved, which drives the rope 14 to move, causing the limiting block 15 and the locking block 16 to move outward against the elastic force of the spring 17. After the locking block 16 is disengaged from the fixing hole 9, the mounting block 7 is removed, the mounting block 7 on the replaced mold is inserted into the inner wall of the mounting groove 6, and the actuating plate 11 is released. The spring 17 pushes the limiting block 15 and the locking block 16 to reset, and the locking block 16 is inserted into the fixing hole 9 of the mounting block 7, thereby firmly fixing the upper mold 8 on the mounting plate 5.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
