Description

Technical Field

[0001] This invention relates to the field of stamping die technology, and in particular to a mechanism for splicing and fixing automotive parts dies. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method that uses dies mounted on a press to apply pressure to materials at room temperature, causing them to separate or plastically deform, thereby obtaining the desired parts.

[0003] In the use of existing automotive parts stamping dies, when the upper and lower dies are damaged or need to be replaced according to processing requirements, it is usually necessary to remove the bolts on the upper and lower dies one by one, and then install the bolts one by one after replacing the upper and lower dies. This makes the replacement process of the upper and lower dies cumbersome and laborious. Especially when installing the upper die on the fixing plate of the upper die holder, the workers usually lift the upper die, press it against the fixing plate, and then fix it with bolts. If the upper die is too heavy to lift, it is necessary to remove the upper die holder, fix the upper die to the upper die holder with the fixing plate and bolts, and then install the upper die holder back on the guide post. This makes fixing the upper die even more difficult and is prone to safety accidents during the installation process. Summary of the Invention

However, this is only for illustrative purposes and is not intended to limit the present invention to this specific structure, device and environment.

[0025] The technical solutions of the present invention will now be described with reference to the accompanying drawings. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some well-known technologies. Furthermore, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0026] like Figures 1 to 6 As shown, an embodiment of the present invention provides an automotive parts mold splicing and fixing mechanism, including: a mold assembly, a lower fixing assembly, and an upper fixing assembly; The mold assembly includes a lower mold base 1, a lower fixing plate 2, a lower mold 3, an upper mold 4, an upper fixing plate 5, an upper mold base 6, and a guide component 7; Both the lower fixing component and the upper fixing component include fixing elements; The lower fixing plate 2 is fixedly installed on the top of the lower mold base 1, the lower mold 3 is fixed on the top of the lower fixing plate 2 by the fixing member of the lower fixing assembly, the upper mold base 6 is fixedly connected to the lower mold base 1 by the guide member 7, the upper fixing plate 5 is fixedly installed on the bottom of the upper mold base 6, the upper mold 4 is installed on the bottom of the upper fixing plate 5 by the fixing member of the upper fixing assembly, and the lower mold 3 is set at the bottom of the upper mold 4; The fastener includes a mounting groove 8, a gear 9, a screw 10, a disassembly rod 11, a first spring 12, and a rack 13.

[0027] In one possible implementation, the fixing members of the lower fixing component and the upper fixing component include mounting grooves 8. The mounting groove 8 of the fixing member of the lower fixing component is formed inside the lower fixing plate 2, and the mounting groove 8 of the fixing member of the upper fixing component is formed inside the upper fixing plate 5.

[0028] The disassembly rod 11 is slidably connected inside the mounting groove 8, the rack 13 is slidably connected inside the disassembly rod 11, the first spring 12 is fixedly installed between the disassembly rod 11 and the rack 13, and the number of gears 9 and screws 10 is set to multiple, the gear 9 is fixedly installed at one end of the screw 10, the gear 9 is located on one side of the disassembly rod 11 and the rack 13, and both the gear 9 and the screw 10 are inserted into the mounting groove 8.

[0029] Among them, the screw 10 in the fixing member of the lower fixing assembly is fixed to the inside of the lower mold 3 by threads, and the screw 10 in the fixing member of the upper fixing assembly is fixed to the inside of the upper mold 4 by threads; Among them, the fastener is used for quick disassembly and assembly of the lower mold 3 and the upper mold 4, which makes it convenient for staff to quickly replace the lower mold 3 and the upper mold 4 as needed, avoiding the cumbersome and laborious disassembly and assembly of the lower mold 3 and the upper mold 4 in the existing technology, and making it convenient for staff to use; It should be noted that when it is necessary to disassemble the lower mold 3 and the upper mold 4, the disassembly rod 11 of the fixing part can be pulled, so that the disassembly rod 11 drives the rack 13 to slide along the inside of the mounting groove 8, and the rack 13 drives the gear 9 to rotate, which in turn drives the screw 10 to rotate, so that the screw 10 disengages from the corresponding lower mold 3 and upper mold 4, stopping the installation and fixing of the lower mold 3 and upper mold 4, making it convenient for workers to quickly disassemble the lower mold 3 and upper mold 4; Furthermore, when it is necessary to install the lower mold 3 and the upper mold 4, the disassembly rod 11 of the fixing component can be pushed, so that the disassembly rod 11 drives the gear 9 to rotate in the opposite direction through the rack 13, so that the gear 9 drives the screw 10 to rotate in the opposite direction, so that the screw 10 is fixed inside the lower mold 3 and the upper mold 4 by the thread, which makes it convenient for the staff to quickly fix the lower mold 3 and the upper mold 4. It is important to note that the teeth on gear 9 and rack 13 are inclined. This allows the teeth of gear 9 and rack 13 to engage when rack 13, via gear 9, drives screw 10 to stop fixing the lower mold 3 and upper mold 4. This prevents rack 13 from sliding along the inside of the disassembly rod 11 and compressing the first spring 12 when driving gear 9 to rotate. This avoids the situation where the teeth of rack 13 and gear 9 become misaligned, preventing rack 13 from failing to drive gear 9 to rotate. Therefore, when rack 13, via gear 9, drives screw 10 to fix the lower mold 3 and upper mold 4, it can... After the screw 10 is tightened to a certain extent, the gear 9 presses against the teeth of the rack 13, causing the rack 13 to compress the first spring 12 and enter the interior of the disassembly rod 11, thus misaligning the rack 13 and the gear 9. This allows all the screws 10 to be tightened to a specific tightness before stopping, maintaining the same tightening force on all the screws 10. This enhances the connection reliability and anti-loosening effect, optimizes the stress distribution of the structure, and avoids the different tightening forces of each screw 10 caused by manual tightening, which could lead to local loosening or stress concentration and affect the fixing effect on the lower mold 3 and the upper mold 4.

[0030] In one possible implementation, the lower fixing assembly further includes two limiting blocks 14 fixedly installed inside the mounting groove 8 of the lower fixing plate 2 and a guide frame 16 sleeved on the outer wall of the lower fixing plate 2. An elastic piece 15 is fixedly connected between the two limiting blocks 14. The elastic piece 15 is disposed on the side of the gear 9 of the fixing member of the lower fixing assembly away from the screw 10. A guide strip 17 is fixedly installed on the inner wall of the guide frame 16. The guide strip 17 abuts against the top outer wall of the lower fixing plate 2. The guide strip 17 is disposed at the bottom of the lower mold 3.

[0031] Among them, the limiting block 14 and the elastic sheet 15 are used to assist the fixing component in fixing the lower mold 3 on the lower fixing plate 2. When the fixing component fixes the lower mold 3, it applies an upward force to the gear 9 and the screw 10 to ensure that the screw 10 can be aligned and pressed against the screw hole of the lower mold 3 placed on the top of the lower fixing plate 2, so as to prevent the screw 10 from being unable to be screwed into the screw hole of the lower mold 3. The guide frame 16 and guide strip 17 are used to assist workers in transporting and positioning the lower mold 3. After the lower mold 3 is placed between the guide frame 16 and the guide strip 17, the lower mold 3 can be moved through the handle on the guide frame 16 until it is placed on the top of the lower fixed plate 2. At this time, the inclined surface of the guide strip 17 will automatically align under the weight of the lower mold 3 and slide down along the chamfer on the top outer wall of the lower fixed plate 2. The lower mold 3 will automatically align under the action of the guide strip 17 and the chamfer on the top of the lower fixed plate 2, so as to avoid deviation in the installation position of the lower mold 3, which would affect the subsequent production of automotive parts. This reduces the difficulty of installing the lower mold 3, improves the installation efficiency of the lower mold 3, and reduces the workload of workers.

[0032] In one possible implementation, the upper fixing assembly further includes two support members 18 sleeved on the outer wall of the upper mold 4. The support members 18 are inserted into the interior of the upper fixing plate 5. The interior of the support member 18 has a slot 19. The slot 19 has a plug 20 inserted into it. The plug 20 is slidably connected to the interior of the upper fixing plate 5. The interior of the plug 20 has a first sliding groove 21.

[0033] The upper fixing plate 5 has a second sliding groove 23 inside, which is connected to the mounting groove 8 of the fixing member of the upper fixing component. A push rod 22 is inserted into the first sliding groove 21 and the second sliding groove 23, and the push rod 22 is inserted into the mounting groove 8.

[0034] The outer wall of the push rod 22 is provided with a first push piece 24 and a second push piece 25, and the first push piece 24 and the second push piece 25 are both fixedly installed on the inner wall of the mounting and dismounting rod 11 of the fixing component of the upper fixing assembly.

[0035] The mounting and dismounting rod 11 of the upper fixing component has a slot 28 inside. The slot 28 is located on the top of the support member 18. A second spring 26 is fixedly installed inside the upper fixing plate 5. A locking block 27 is fixedly installed at one end of the second spring 26. The end of the locking block 27 away from the second spring 26 abuts against one side of the support member 18.

[0036] A connecting rod 29 is slidably connected between the two support members 18. Threaded rods 30 are fixedly installed on the sides of the two support members 18 that are away from the connecting rod 29 and close to each other. The outer walls of the two threaded rods 30 are connected by a bidirectional threaded sleeve 31 through a thread.

[0037] Support bars 32 are fixedly connected to the bottom of the two support members 18 on their sides that are close to each other, and the support bars 32 abut against the bottom of the upper mold 4.

[0038] The support frame structure, consisting of support member 18, connecting rod 29, threaded rod 30, and bidirectional threaded sleeve 31, allows workers to rotate the bidirectional threaded sleeve 31 when dismantling the upper mold 4. This causes the bidirectional threaded sleeve 31 to pull the two support members 18 closer together via the two threaded rods 30 until the support bar 32 on the support member 18 is engaged at the bottom of the upper mold 4. At this point, the worker can pull the fixing member to remove the fixing between the upper mold 4 and the upper fixing plate 5. The upper mold 4 will then be supported and fixed by the support frame structure and will not fall downwards. The worker can then push the support frame structure to move the upper mold 4 out from the bottom of the upper fixing plate 5. The worker can then move the upper mold 4 through the support frame structure, allowing for single-person dismantling of the upper mold 4 without the need for other workers to lift it or remove the upper mold base 6 before dismantling the upper mold 4. This simplifies the dismantling process, reduces the difficulty of dismantling the upper mold 4, and facilitates the disassembly and assembly of the upper mold 4. The second spring 26, the locking block 27, and the slot 28 are designed so that when the support member 18 is not engaging the support bar 32 at its bottom, the second spring 26 will cause the locking block 27 to insert into the slot 28, thus limiting and fixing the disassembly rod 11 in the fixing member, preventing the fixing member from removing the upper mold 4. Only when the support member 18 engages the support bar 32 at its bottom can the support member 18 push the locking block 27 to compress the second spring 26 and disengage it from the slot 28. Only then can the fixing member remove the upper mold 4, ensuring that the workers can remove the upper mold. 4. Safety during the process: To prevent workers from forgetting to support the upper mold 4 with the support member 18 and support bar 32 before removing the upper mold 4, which could cause the upper mold 4 to fall and hit the lower mold 3, resulting in mold damage or even injury to workers, it is important to note that after the upper mold 4 is installed, the bidirectional threaded sleeve 31 needs to be rotated in the reverse direction. This will cause the bidirectional threaded sleeve 31 to drive the corresponding support member 18 away from each other through the two threaded rods 30, allowing the two support members 18 to drive the corresponding support bar 32 to fall off from the bottom of the upper mold 4. This will prevent the upper mold 4 from obstructing the subsequent descent of the upper mold 4 for stamping and processing of automotive parts. The arrangement of slot 19, insert block 20, push rod 22, second slide groove 23, first push piece 24, and second push piece 25 allows the fastener to lock the upper mold 4. During this process, the fastener's disassembly rod 11 drives the second push piece 25 to push the push rod 22 along the inside of the second slide groove 23. This causes the push rod 22 to slide along the inside of the first slide groove 21 and push the insert block 20 into the slot 19 of the support member 18, thus limiting the support member 18 to the outer wall of the upper fixing plate 5 for subsequent use. It should be noted that during the process of removing the upper mold 4 from the fastener, the fastener's disassembly rod 11 will push the push rod 22 back to its original position via the first push piece 24. This causes the push rod 22 to slide back to its original position along the inside of the second slide groove 23 and the first slide groove 21 and pull the insert block 20 out of the slot 19 of the support member 18, stopping the limitation on the support member 18. This allows the support member 18 to move the removed upper mold 4 out from the bottom of the upper fixing plate 5.

[0039] In summary, the automotive parts mold splicing and fixing mechanism designed in this invention can simplify the disassembly and assembly of the lower mold 3 and the upper mold 4, ensuring that the lower mold 3 and the upper mold 4 can be quickly disassembled and assembled. It can also control the tightening force of the screws 10, avoiding different tightening forces of each screw 10, which could lead to local loosening or stress concentration. At the same time, it can guide and limit the installation of the lower mold 3 and support the upper mold 4, reducing the labor intensity of workers and enhancing safety.

It also ensures that the screws 10 installed on the lower mold 3 and the upper mold 4 are tightened with the same force, enhancing connection reliability and loosening effect, optimizing the stress distribution of the structure, and avoiding uneven tightening of the screws 10 caused by manual tightening, which could lead to localized loosening or stress concentration. Simultaneously, when installing the lower mold 3, it is guided and limited to ensure that the lower mold 3 is accurately fixed to the top of the lower fixing plate 2, preventing deviations in the installation position of the lower mold 3. Furthermore, when assembling and disassembling the upper mold 4, it is supported, reducing the labor intensity of workers and enhancing safety.
