In automobile production, stamping technology is widely used in the processing of various parts, and stamping dies, as key equipment for realizing the stamping process, directly affect the production efficiency, quality, and cost of automotive parts.

[0003] With the continuous development of the automotive industry, market demand for automobiles is becoming increasingly diversified. This requires automotive manufacturers to quickly adjust their production processes to produce automotive parts of different models and specifications. In this process, the frequency of stamping die replacement has increased significantly. Traditional automotive parts stamping dies present many inconveniences in terms of die replacement. For example, the common method of installing and disassembling dies using standardized threads, connecting interfaces, and fixing holes, while enabling die replacement to some extent, requires operators to spend a significant amount of time loosening and disassembling bolts, as well as aligning and fixing the new die. This results in lengthy replacement times, severely impacting production efficiency and increasing production costs. Therefore, improvements are needed. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides an automotive parts stamping die that is easy to replace, with the advantage of being able to easily replace the lower die.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stamping die for automotive parts that facilitates die replacement, comprising: A fixed plate, the top of which has a positioning groove, a positioning block is slidably connected inside the positioning groove, a lower mold is fixedly installed on the top of the positioning block, and a groove is provided on the lower mold; A fixing mechanism is disposed inside the fixing plate; The fixing mechanism includes a slider, the outer surface of which is slidably connected to the interior of a fixing plate.

[0014] 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.

[0015] like Figures 1 to 6 As shown, this utility model provides a stamping die for automotive parts that facilitates die replacement, comprising: A fixed plate 1 has a positioning groove 2 at its top end. A positioning block 3 is slidably connected inside the positioning groove 2. A lower mold 4 is fixedly installed at the top end of the positioning block 3. A groove is provided on the lower mold 4. The fixing mechanism is located inside the fixing plate 1; The fixing mechanism includes a slider 5, the outer surface of which is slidably connected to the interior of the fixing plate 1. A fixing sleeve 6 is fixedly installed on the outer surface of the slider 5. A lead screw 7 is movably sleeved inside the bottom end of the fixing sleeve 6. A turning block 8 is fixedly installed at the bottom end of the lead screw 7. A telescopic block 9 is movably sleeved inside the fixing sleeve 6. The outer surface of the lead screw 7 is threadedly sleeved with the interior of the telescopic block 9. A moving block 10 is fixedly installed at the top end of the telescopic block 9. An extrusion shaft 11 is fixedly sleeved inside the moving block 10. A connecting rod 12 is slidably connected to the outer surface of the extrusion shaft 11. The end of the connecting rod 12 away from the extrusion shaft 11 abuts against a groove on the lower die 4. A hinge block 13 is fixedly installed on the outer surface of the connecting rod 12. A connecting rod 14 is hinged to the outer surface of the hinge block 13. The bottom end of the connecting rod 14 is fixedly connected to the top end of the slider 5.

[0016] The fixed plate 1 serves as the basic load-bearing structure of the entire stamping die, providing an installation platform for other components. The positioning groove 2 and the positioning block 3 cooperate to achieve rapid and precise positioning when installing the lower die 4, ensuring the accuracy of the lower die 4's installation position. The lower die 4 is used to support the material to be stamped, and its groove provides the action point for the fixing mechanism. The fixing mechanism adjusts its position by sliding the slider 5 within the fixed plate 1. The fixing sleeve 6 provides installation and movement space for the lead screw 7 and the telescopic block 9, and the turning block 8 facilitates the operator's rotation of the lead screw. 7. When the lead screw 7 rotates, it drives the telescopic block 9 to move up and down through the threaded engagement with the telescopic block 9. The telescopic block 9 drives the extrusion shaft 11 to move synchronously through the moving block 10. When the extrusion shaft 11 moves downward, it extrudes the connecting rod 12, causing the connecting rod 12 to rotate around the hinge point of the hinge block 13 and the connecting rod 14. This allows the end of the connecting rod 12 away from the extrusion shaft 11 to abut against or disengage from the groove of the lower mold 4, thereby fixing or loosening the lower mold 4. The connecting rod 14 connects the hinge block 13 and the slider 5, providing a fulcrum for the rotation of the connecting rod 12.

[0017] The bottom end of the fixing plate 1 is fixedly installed with a base frame 25, and a reinforcing rod 26 is provided on the base frame 25.

[0018] The base frame 25 is installed at the bottom of the fixed plate 1 to provide stable support for the entire stamping die, making the device less prone to shaking during operation. The reinforcing rod 26 is set on the base frame 25 to enhance the structural strength of the base frame 25, improve the load-bearing capacity of the base frame 25, and further ensure the stability of the device.

[0019] The top of the fixed plate 1 is fixedly installed with a column 21, the top of the column 21 is fixedly installed with a top plate 22, the top of the top plate 22 is fixedly installed with a cylinder 23, the output end of the cylinder 23 is fixedly installed with an upper mold 24, and the interior of the upper mold 24 is movably connected to the outer surface of the column 21.

[0020] The column 21 is fixed to the top of the fixed plate 1, which supports the top plate 22 and provides guidance for the up and down movement of the upper mold 24. The top plate 22 is used to install the cylinder 23. The cylinder 23 is a power component. Its output end drives the upper mold 24 to move up and down along the outer surface of the column 21. When the upper mold 24 moves downward, it cooperates with the lower mold 4 to complete the stamping operation of the material.

[0021] The fixed plate 1 has two bidirectional screws 15 inside, and the outer surfaces of the two bidirectional screws 15 are threaded into the slider 5.

[0022] The bidirectional screw 15 is movably sleeved inside the fixed plate 1, and its outer surface is threaded into the slider 5. The two bidirectional screws 15 work together to drive the slider 5 to slide along the inside of the fixed plate 1 when rotating. By adjusting the position of the slider 5, space is provided for the replacement of the lower mold 4 or the lower mold 4 can be fixed.

[0023] The outer surfaces of the two bidirectional screws 15 are respectively fixedly sleeved with a drive toothed pulley 16 and a driven toothed pulley 17. A rocker handle 19 is fixedly installed on the left end of the bidirectional screw 15 with the drive toothed pulley 16 fixedly sleeved. The drive toothed pulley 16 and the driven toothed pulley 17 are connected by a toothed belt 18.

[0024] Two bidirectional screws 15 are respectively fitted with a drive toothed pulley 16 and a driven toothed pulley 17 on their outer surfaces. A rocker handle 19 is installed on the left end of the bidirectional screw 15, which is fixedly fitted with the drive toothed pulley 16. When the operator turns the rocker handle 19, the bidirectional screw 15 and the drive toothed pulley 16 can be rotated. The drive toothed pulley 16 transmits power to the driven toothed pulley 17 through the toothed belt 18, so that the driven toothed pulley 17 drives the other bidirectional screw 15 to rotate synchronously, thereby realizing the synchronous movement of the two bidirectional screws 15 and ensuring the consistency of the movement of the slider 5.

[0025] Among them, the outer surfaces of the two bidirectional screws 15 are movably fitted with protective shells 20, and the outer surfaces of the protective shells 20 are fixedly connected to the left side of the fixed plate 1. The drive toothed pulley 16, the driven toothed pulley 17 and the toothed belt 18 are all located inside the protective shells 20.

[0026] The protective shell 20 is movably sleeved on the outer surface of the two bidirectional screws 15 and fixedly connected to the left side of the fixing plate 1. It encloses the drive toothed pulley 16, the driven toothed pulley 17 and the toothed belt 18 inside, which can prevent external dust, impurities and other contaminants from entering, avoid these components from being contaminated or damaged, and at the same time prevent the operator from accidentally touching them during operation, thus improving the safety of the device.

[0027] Working principle and usage process of this utility model: When cylinder 23 is running, its output end will drive the upper die 24 to move downward along the outer surface of column 21. At this time, the upper die 24 will cooperate with the lower die 4 to stamp the material located at the top of the lower die 4. Due to the design of column 21, it can provide guidance for the up and down movement of upper die 24, making the movement of upper die 24 more stable and ensuring the accuracy of the stamping process. When the operator needs to replace the lower mold 4, the four turning blocks 8 need to be turned in sequence. At this time, the turning blocks 8 will drive the lead screw 7 to rotate inside the fixed sleeve 6. Since the outer surface of the lead screw 7 is threaded with the inner thread of the telescopic block 9, and the outer surface of the telescopic block 9 is slidably connected with the inner part of the fixed sleeve 6, the lead screw 7 will drive the telescopic block 9 to move downward along the inner part of the fixed sleeve 6 during the rotation. At the same time, the telescopic block 9 will drive the extrusion shaft 11 to move downward synchronously through the moving block 10. At this time, the outer surface of the extrusion shaft 11 will exert a squeezing and pushing effect on the inner part of the connecting rod 12 during the downward movement, so that the connecting rod 12 rotates around the hinge point of the hinge block 13 and the connecting rod 14 as the axis. During this process, the end of the connecting rod 12 away from the extrusion shaft 11 will gradually disengage from the groove on the lower mold 4 during the rotation, thereby releasing the fixation of the lower mold 4. Then the operator cranks the handle 19. Since the handle 19 is fixedly installed on the left end of the bidirectional screw 15, which is fitted with the drive toothed pulley 16, the handle 19 will drive the bidirectional screw 15 to rotate. At this time, the drive toothed pulley 16 will rotate with the bidirectional screw 15, and drive the driven toothed pulley 17 to rotate through the toothed belt 18. The driven toothed pulley 17 will then drive the other bidirectional screw 15 fitted with it to rotate synchronously. Since the outer surfaces of the two bidirectional screws 15 are respectively fitted with the internal threads of the two sets of sliders 5, when the two bidirectional screws 15 rotate synchronously, they will drive the two sets of sliders 5 to move in opposite directions along the inside of the fixed plate 1. Subsequently, the two sets of sliders 5 will gradually move to the front and rear of the lower mold 4 during the opposite movement, no longer obstructing the movement of the lower mold 4. After that, the operator can pull the lever. The lower mold 4 moves forward along the inside of the positioning groove 2, causing the positioning block 3 to completely disengage from the positioning groove 2. When the positioning block 3 is completely disconnected from the positioning groove 2, the lower mold 4 is easily removed from the fixing plate 1. When installing the new lower mold 4, the operator needs to align the positioning block 3 at the bottom of the new lower mold 4 with the positioning groove 2 on the fixing plate 1. Due to the matching design of the positioning block 3 and the positioning groove 2, the lower mold 4 and the fixing plate 1 can be well positioned, ensuring the accuracy of the installation position of the lower mold 4. After positioning, the operation is carried out in the reverse order of disassembly. That is, first, the double screw 15 is rotated by the crank handle 19, so that the two sets of sliders 5 move towards each other to both sides of the lower mold 4. Then, the screwing block 8 is turned in the opposite direction, so that the connecting rod 12 abuts against the groove of the lower mold 4 again, thus completing the fixing of the new lower mold 4. The entire replacement process is then completed smoothly.

[0028] In addition, the protective shell 20 can provide good protection for the drive toothed pulley 16, the driven toothed pulley 17 and the toothed belt 18. The base frame 25 and the reinforcing rod 26 provide stable support for the entire device. At the same time, in order to further prevent dust and other impurities from entering the interior of the fixed plate 1 and affecting the normal operation of the bidirectional screw 15, a telescopic baffle or a dustproof brush can be added to the front of the fixed plate 1. When the slider 5 moves, the telescopic baffle can extend and retract with the movement of the slider 5, always covering the exposed part of the bidirectional screw 15. The dustproof brush can block dust with its fine bristles, thereby effectively improving the dustproof effect of the bidirectional screw 15 and ensuring its operational stability and service life.
