Description

Technical Field

[0001] This utility model belongs to the field of stamping die technology, and in particular relates to an automotive parts processing die with a protective mechanism. Background Technology

[0002] Automotive parts processing molds are special tools used in the automobile manufacturing process to form and process metal or non-metal parts. Their precision and performance directly affect the quality, production efficiency and cost of automotive parts. Common processing molds include stamping molds, injection molds, die casting molds and forging molds. Therefore, it can be seen that the existing stamping molds basically meet people's needs, but the following problems still exist.

[0003] When an operator uses a stamping die to process automotive parts, the operator sets up the die on a stamping machine and then starts the machine, causing it to press the die to extrude or cut the raw material, thus producing automotive parts. However, when using a stamping die, the operator may need to manually unload the raw material and unload the product. Because of this manual operation, the operator's hands may be squeezed by the die during loading and unloading, potentially causing hand injuries. Therefore, we propose an automotive parts processing die with a protective mechanism. Utility Model Content

[0004] This utility model provides an automotive parts processing mold with a protective mechanism. By passing a positioning block through a traction plate, the positioning block and the traction plate restrict the mold body, preventing the operator from accidentally touching the buttons of the stamping machine and being pinched by the mold after the stamping machine squeezes the mold, thus improving the usability for the operator.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mold for processing automotive parts with a protective mechanism, comprising a mold body, wherein a first mounting block and a second mounting plate are rotatably connected to the surface of the mold body, and a traction plate is fixed to the surface of the first mounting block, and a traction groove is sleeved at the end of each traction plate in the middle of the second mounting plate, a fixing block is fixed to the surface of each traction groove, and a spring groove and a limiting groove are respectively opened in the middle of the fixing block, a positioning block and a positioning plate are respectively inserted into the middle of the spring groove and the limiting groove, and the positioning plate is elastically connected to the positioning block, one side of the positioning block penetrates the traction plate, and the other end of the positioning block is sleeved with a positioning groove opened on the inner wall of the traction groove.

[0006] Furthermore, both the first mounting block and the second mounting plate have sliders fixed on the side that is in contact with the mold body, and the surface of the sliders is provided with grooves opened in the mold body.

[0007] Furthermore, bolts are inserted into the ends of both the first mounting block and the second mounting plate, and the bolts pass through and are fixed to the sliders on the first mounting block and the second mounting plate. The ends of the bolts are fitted with threaded grooves opened on the inner wall of the slide groove.

[0008] Furthermore, each of the traction plates has a waist-shaped hole in the middle, and a traction rod passes through the middle of each waist-shaped hole in the traction plate, with both ends of the traction rod fixed to the inner wall of the traction groove.

[0009] Furthermore, each of the positioning plates is rotatably connected to a connecting block on the side near the positioning block, and each connecting block has a pull rod fixed to the outer wall of the connecting block, passing through the spring groove. Each pull rod has a positioning block fixed to its end, and each pull rod has a traction sleeve fixed to the inner wall of the spring groove. Each pull rod has a spring wound around its surface, which abuts against the surfaces of the positioning block and the traction sleeve.

[0010] Furthermore, each of the connecting blocks has a rotating groove in the middle, and each rotating groove has a rotating block embedded in it. Each rotating block is fixed to the positioning plate. Each of the connecting blocks has a guide groove on the outer side wall near the positioning plate, and a guide sleeve fixed to the positioning plate is fitted on the surface of the guide groove.

[0011] Furthermore, each of the outer walls of the positioning plate is fixed with a handle, and the surface of the handle is provided with several sets of wavy grooves.

[0012] The beneficial effects of this utility model are:

[0013] 1. The automotive parts processing mold with a protective mechanism is equipped with a second mounting plate, a traction groove, a positioning block, and a traction plate. After the mold body is reset, the mold body slides on the surface of the traction plate via the second mounting plate, causing the second mounting plate to move the positioning block to the notch in the middle of the traction plate. Then, the positioning block passes through the traction plate and is inserted into the positioning groove, so that the positioning block and the traction plate fix the position of the mold body. This prevents the operator from accidentally pressing the button of the stamping machine and being pinched by the mold after the stamping machine squeezes the mold, thus improving the usability for the operator.

[0014] 2. The automotive parts processing mold with protective mechanism is equipped with a slider and a groove. By the operator moving the first mounting block and the second mounting plate, the first mounting block and the second mounting plate drive the slider to insert into the groove. The slider slides in the groove, installing the first mounting block and the second mounting plate on both sides of the mold body. This facilitates the operator's installation of the first mounting block and the second mounting plate. Furthermore, if the operator accidentally touches the stamping machine, causing the stamping die to be squeezed, the positioning block and the traction plate will deform after being squeezed by the stamping die. This facilitates the replacement of the second mounting plate and the first mounting block, thus improving the operator's ease of maintenance. Attached Figure Description

[0024] To further understand the utility model's content, features, and effects, the following embodiments are provided, along with detailed descriptions in conjunction with the accompanying drawings.

[0025] Example:

[0026] Please see Figure 1 - Figure 7A mold for processing automotive parts with a protective mechanism includes a mold body 1. A first mounting block 2 and a second mounting plate 4 are rotatably connected to the surface of the mold body 1. A traction plate 3 is welded to the surface of each of the first mounting blocks 2. Each traction plate 3 has a traction groove 8 formed in the middle of the second mounting plate 4 at its end. A fixing block 5 is welded to the surface of each traction groove 8. A spring groove 9 and a limiting groove 15 are respectively formed in the middle of each fixing block 5. A positioning block 22 and a positioning plate 11 are respectively inserted into the spring groove 9 and the limiting groove 15. The positioning plate 11 is elastically connected to the positioning block 22. A connecting block 21 is rotatably connected to the side of the positioning plate 11 closest to the positioning block 22. A groove passing through the spring groove 9 is welded to the outer wall of each connecting block 21. A pull rod 14 has a positioning block 22 welded to its end. A traction sleeve 10, welded to the inner wall of a spring groove 9, is fitted onto the surface of the pull rod 14. Springs 13, respectively abutting against the surfaces of the positioning block 22 and the traction sleeve 10, are wound around the surface of the pull rod 14. One side of the positioning block 22 passes through the traction plate 3, and the other end of the positioning block 22 is fitted with a positioning groove 12 formed on the inner wall of the traction groove 8. When in use, the operator first pulls the positioning plate 11, which moves the pull rod 14, causing it to slide within the traction sleeve 10. Through this sliding motion, the traction sleeve 10 guides the movement of the pull rod 14, and also increases the distance the pull rod 14 passes through. The contact area on one side of the spring groove 9 is used to ensure the stability of the movement of the pull rod 14. When the pull rod 14 moves, it drives the positioning block 22 to move. When the positioning block 22 moves, it compresses the spring 13 wrapped around the surface of the pull rod 14, causing the spring 13 to undergo elastic deformation. After the spring 13 undergoes elastic deformation, it avoids the positioning block 22, and the positioning block 22 moves out of the positioning groove 12. At the same time, the positioning block 22 moves out of the notch in the middle of the traction plate 3. Finally, the positioning block 22 enters the spring groove 9, so that the positioning block 22 no longer supports the mold body 1 through the traction plate 3. When the operator pulls the positioning plate 11, the positioning plate 11 moves within the limiting groove 1. The mold body 1 slides through the rectangular notch on the surface of the 5-piece mold. After the stamping is completed by the press, the mold body 1 is reset. The operator releases the positioning plate 11. The positioning plate 11 no longer compresses the spring 13 through the pull rod 14. The spring 13 recovers its elastic deformation and pushes the positioning block 22 to move. The positioning block 22 moves out of the spring groove 9 and passes through the notch on the surface of the traction plate 3. The positioning block 22 is then inserted back into the positioning groove 12. The positioning block 22 and the traction plate 3 fix the position of the mold body 1. This prevents the operator from accidentally pressing the press button and causing the press to squeeze the mold, which could then pinch the operator's hand. This improves the usability for the operator.

[0027] In other embodiments, sliders 6 are welded to the sides of the first mounting block 2 and the second mounting plate 4 that are in contact with the mold body 1, and the surface of the sliders 6 is fitted with grooves 7 formed in the mold body 1. When the operator needs to install the first mounting block 2 and the second mounting plate 4 on both sides of the mold body 1, the operator first moves the first mounting block 2 and the second mounting plate 4, which drives the sliders 6 to move, aligning the sliders 6 with the grooves 7. After the sliders 6 and the grooves 7 are aligned, the sliders 6 are inserted into the grooves 7. After the first mounting block 2 and the second mounting plate 4 are installed in the groove 7, the operator pushes the first mounting block 2 and the second mounting plate 4, causing the slider 6 to slide in the groove 7. This makes it convenient for the operator to install the first mounting block 2 and the second mounting plate 4 on both sides of the mold body 1. Furthermore, if the operator accidentally touches the stamping machine, causing the stamping machine to squeeze the stamping mold, the positioning block 22 and the traction plate 3 will deform after squeezing the stamping mold, making it convenient to replace the second mounting plate 4 and the first mounting block 2. This facilitates maintenance for the operator.

[0028] In other embodiments, bolts 24 are inserted into the ends of both the first mounting block 2 and the second mounting plate 4, and the bolts 24 pass through the sliders 6 welded to the first mounting block 2 and the second mounting plate 4. The ends of the bolts 24 are fitted with threaded grooves 25 opened on the inner wall of the slide groove 7. When the operator installs the first mounting block 2 and the second mounting plate 4 on both sides of the mold body 1, the operator pushes the first mounting block 2 and the second mounting plate 4 to align the mounting holes opened on both sides of the slider 6, the first mounting block 2 and the second mounting plate 4 with the threaded grooves 25 opened on the inner wall of the slide groove 7. Then the operator passes the bolts 24 through the mounting holes opened on the first mounting block 2, the second mounting plate 4 and the slider 6, and threads the ends of the bolts 24 with the threaded grooves 25 to fix the position of the slider 6 in the slide groove 7, thereby fixing the positions of the first mounting block 2 and the second mounting plate 4 on both sides of the mold body 1, preventing the first mounting block 2 and the second mounting plate 4 from sliding on both sides of the mold body 1 when the operator uses the first mounting block 2 and the second mounting plate 4.

[0029] In other embodiments, each traction plate 3 has a waist-shaped hole in its middle, and a traction rod 23 passes through the middle of each waist-shaped hole in the traction plate 3. The two ends of the traction rod 23 are welded to the inner wall of the traction groove 8. When the mold body 1 is squeezed by the stamping machine, the mold body 1 drives the second mounting plate 4 to move. The traction groove 8 in the middle of the second mounting plate 4 slides on the surface of the traction plate 3, so that the traction groove 8 avoids the traction plate 3. When the traction groove 8 slides on the surface of the traction plate 3, the cylindrical traction rod 23 fixed on the inner wall of the traction groove 8 slides in the waist-shaped hole in the surface of the traction plate 3, so that the waist-shaped hole in the middle of the traction plate 3 avoids the traction rod 23. When the traction rod 23 slides in the waist-shaped hole in the middle of the traction plate 3, it is convenient to pull the traction plate 3 and increase the stability of the traction groove 8 sliding on the surface of the traction plate 3.

[0030] In other embodiments, each connecting block 21 has a rotating groove 19 in its middle, and each rotating groove 19 has a rotating block 20 embedded in it. The rotating blocks 20 are welded to the positioning plate 11. Each connecting block 21 has a guide groove 17 on its outer side wall near the positioning plate 11, and a guide sleeve 18 welded to the positioning plate 11 is fitted onto the surface of the guide groove 17. When the operator pulls the positioning plate 11 to slide within the limiting groove 15, and after the positioning plate 11 moves out of the limiting groove 15, the operator rotates the positioning plate 11. The positioning plate 11 then drives the rotating blocks 20 to rotate within the rotating groove 19, thus positioning the blocks. The plate 11 rotates and aligns the positioning plate 11 with another rectangular notch on the surface of the limiting groove 15. Then, the operator releases the positioning plate 11, and the spring 13 drives the pull rod 14 to move through the positioning block 22. The pull rod 14 drives the positioning plate 11 to the other rectangular notch on the surface of the limiting groove 15. After the positioning plate 11 is inserted into the other rectangular notch on the surface of the limiting groove 15, the positioning plate 11 fixes the position of the positioning block 22 through the pull rod 14. The operator no longer needs to keep pulling the positioning plate 11, which improves the safety of the operator.

[0031] Furthermore, when the positioning plate 11 rotates, it drives the guide sleeve 18 to move, causing the guide sleeve 18 to rotate on the surface of the guide groove 17, thereby increasing the stability of the positioning plate 11 rotating on the surface of the connecting block 21.

[0032] In other embodiments, a handle 16 is welded to the outer wall of the positioning plate 11, and a number of wavy grooves are formed on the surface of the handle 16. When the operator pulls the positioning plate 11, the operator holds the handle 16 and then pulls the handle 16, which moves the positioning plate 11, making it convenient for the operator to pull the positioning plate 11.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
