Description

Technical Field

[0001] This invention relates to the technical field of automotive parts molds, and more particularly to a flexible recess forming mold for automotive structural parts. Background Technology

[0002] As one of the most important modes of transportation in modern times, the weight of automobiles has always been a major concern. Currently, the most common method for reducing automobile weight is the use of a combination of multiple materials. Electromagnetic pulse spot welding, as a solid-state welding technology, can be used for welding dissimilar metals and can achieve welding without melting the materials, thus possessing enormous development potential in the automotive manufacturing industry.

[0003] The use of multiple materials in automotive beam-type structural components has great development potential. With structural optimization, it is easy to replace areas with less demanding strength requirements with lightweight metals such as aluminum alloys, for example, an aluminum-steel hybrid cap-shaped beam energy-absorbing box. Currently, the stamping process for automotive body structures does not include the welding gap required for electromagnetic pulse spot welding. Therefore, to enable the application of electromagnetic pulse spot welding on the vehicle body, it is necessary to process the body with recessed features to create the welding gap. However, the forming positions of the recesses differ on different automotive beam-type structural components. Therefore, to achieve the application of electromagnetic pulse spot welding on the vehicle body, a mold suitable for forming the recess positions of different automotive beam-type structural components needs to be designed.

[0035] Example 1

[0036] Reference Figures 1 to 3 A flexible recess forming mold for automotive structural parts is provided, including a mold body 100, including an upper mold base 101 and a lower mold base 102; and a position adjustment mechanism G; multiple mold bodies 100 are connected by the position adjustment mechanism G, which can adjust the positional relationship between the multiple mold bodies 100, so that the positional relationship between the multiple mold bodies 100 can be adjusted according to the recess position to be formed for different automotive structural parts.

[0037] The upper mold base 101 includes an upper mold component 101a, a pressure head 101b detachably connected to the upper mold component 101a, and a forming punch 101c installed in the pressure head 101b. Different forming punches 101c can be selected according to the shape and size of the concave hole on the automotive structural component.

[0038] The lower mold base 102 includes a lower mold component 102a and a forming die 102b mounted on the lower mold component 102a. The size and shape of the forming die 102b match the forming punch 101c.

[0039] Specifically, the position adjustment mechanism G includes a connecting component 200, an upper rotating shaft 201 capable of rotatably connecting multiple upper mold bases 101, and a lower rotating shaft 202 capable of rotatably connecting multiple lower mold bases 102; and a positioning component 300, including a follower component 301 connected to the upper rotating shaft 201, and a fixing component 302 capable of positioning the follower component 301.

[0040] Connecting ears 103 are fixed on both sides of the upper mold base 101 and the lower mold base 102. When the two mold bodies 100 are connected, the upper rotating shaft 201 and the lower rotating shaft 202 are fixedly connected to the connecting ear 103 of one of the mold bodies 100, and the connecting ear 103 of the other mold body 100 is rotatably sleeved on the outside of the upper rotating shaft 201 and the lower rotating shaft 202. The upper rotating shaft 201 and the lower rotating shaft 202 are coaxially arranged, so that the angle between the two mold bodies 100 can be adjusted. After the adjustment is completed, the angle adjustment and fixation between the two mold bodies 100 can be completed by fixing the rotating part 301 with the fixing part 302. In application, according to the different positions of the concave holes on different automotive structural parts, the angle and position between multiple mold bodies 100 can be adjusted to adapt to the different concave hole forming requirements of automotive structural parts.

[0041] Of course, in this embodiment, the number of mold bodies 100 is not limited to two.

[0042] Furthermore, the rotating component 301 is a ratchet 301a disposed on the upper rotating shaft 201; the fixing component 302 includes a positioning seat 302a connected to the upper mold base 101, a pushing body 302b connected to the positioning seat 302a, and a pawl 302c disposed at the end of the pushing body 302b; the pushing body 302b can push the pawl 302c to lock the ratchet 301a.

[0043] The ratchet 301a can rotate synchronously with the upper rotating shaft 201. The pusher 302b is a lead screw, which is threadedly connected to the positioning seat 302a. The pawl 302c is slidably connected to the positioning seat 302a. A guide block is set on the pawl 302c, and a guide groove is opened in the positioning seat 302a. The guide block slides inside the guide groove. The pawl 302c and the lead screw are rotatably connected. After the two mold bodies 100 have completed the angle adjustment, by rotating the lead screw, the pawl 302c is pushed to move towards the ratchet 301a. The pawl 302c engages with the ratchet 301a, thereby fixing the position between the two mold bodies 100.

[0044] Similarly, the angle between the two lower mold bases 102 can also be locked through the position adjustment mechanism G, which will not be elaborated here.

[0045] After the angle adjustment between two or more mold bodies 100 is completed, the two mold bodies 100 and the multiple mold bodies 100 constitute a mold assembly 1000 capable of forming multiple concave holes at one time. At both ends of the mold assembly 1000, the upper mold base 101 and the lower mold base 102 of the mold assembly 1000 are connected by a frame mechanism 2000. The frame mechanism 2000 includes a support column 2001 that passes through the connecting ears 103 at both ends of the mold assembly 1000. Limiting blocks 2002 are provided at both ends of the support column 2001. An elastic support member 2003 is provided between the connecting ears 103 of the upper mold base 101 and the lower mold base 102. The elastic support member 2003 can be a spring or other materials that can deform and have elasticity, such as rubber.

[0046] A top block 104 is fixed on the top of the upper mold base 101. When the hydraulic press is pressed down, the top block 104 presses down on the upper mold base 101 to prevent the position adjustment mechanism G from being pressed. Since the position adjustment mechanism G is provided on the lower mold base 102, a bottom block can be provided at the bottom of the lower mold base 102 to prevent the position adjustment mechanism G provided on the lower mold base 102 from being pressed.

[0047] Operation process: When the two mold bodies 100 are connected, the upper rotating shaft 201 and the lower rotating shaft 202 are fixedly connected to the connecting ear 103 of one of the mold bodies 100. The connecting ear 103 of the other mold body 100 is rotatably sleeved on the outside of the upper rotating shaft 201 and the lower rotating shaft 202. The upper rotating shaft 201 and the lower rotating shaft 202 are coaxially arranged, so that the angle between the two mold bodies 100 can be adjusted. After the adjustment is completed, the rotating part 301 is fixed by the fixing part 302 to complete the angle adjustment and fixation between the two mold bodies 100. In application, according to the different positions of the concave holes on different automotive structural parts, the angle and position between multiple mold bodies 100 can be adjusted to form multiple concave holes at one time, thereby adapting to the concave hole forming requirements of different automotive structural parts.

[0048] Example 2

[0049] Reference Figures 4 to 6 The difference between this embodiment and the first embodiment is that the position adjustment mechanism G in this embodiment includes an upper mold adjustment component 400, which is rotatably connected to multiple upper mold bases 101; a lower mold adjustment component 500, which is rotatably connected to multiple lower mold bases 102; and a synchronization component 600, which is capable of synchronizing the upper mold bases 101 and lower mold bases 102 located in the same mold body 100.

[0050] The upper mold adjustment component 400 can rotatably connect the upper mold bases 101 of the two mold bodies 100. The two upper mold bases 101 after connection can be adjusted in position with the upper adjustment component as the axis. Similarly, the lower mold adjustment component 500 can rotatably connect the lower mold bases 102 of the two mold bodies 100. The two lower mold bases 102 after connection can be adjusted in position with the lower adjustment component as the axis.

[0051] The rest of the structure is the same as in Example 1.

[0052] Operation process: During the adjustment of the upper mold base 101 and lower mold base 102 of the two mold bodies 100, the synchronization component 600 enables the upper mold base 101 and lower mold base 102 of the mold body 100 that have been displaced to move synchronously, thereby enabling the upper mold base 101 and lower mold base 102 of the same mold body 100 to move synchronously and maintain alignment.

[0053] Before using a hydraulic press to press the mold body 100, disconnecting the synchronous component 600 from the upper mold base 101 and the lower mold base 102 allows the automotive structural component to pass through multiple mold bodies 100 simultaneously and be processed by multiple mold bodies 100 at the same time.

[0054] Example 3

[0055] Reference Figures 4 to 10 This embodiment differs from the previous embodiments in that: the upper mold adjustment component 400 includes an upper positioning ear 401 and an upper adjusting ear 402 respectively disposed on both sides of the upper mold base 101, and an upper insertion pin 403 slidably connected to the upper positioning ear 401 and rotatably connected to the upper adjusting ear 402; the upper insertion pin 403 and the upper positioning ear 401 are slidably connected by a protrusion and groove 402c structure, and the upper adjusting ear 402 is rotatably sleeved on the inner side of the upper insertion pin 403, so that the upper mold base 101, on which the upper adjusting ear 402 is sleeved on the outer side of the upper insertion pin 403, can rotate with the upper insertion pin 403 as the axis.

[0056] The lower mold adjustment component 500 includes a lower positioning ear 501 and a lower adjusting ear 502 distributed on both sides of the lower mold base 102, and a lower insertion pin 503 that is slidably connected to the lower positioning ear 501 and rotatably connected to the lower adjusting ear 502; the lower insertion pin 503 is rotatably connected to the lower adjusting ear 502; the lower insertion pin 503 and the lower positioning ear 501 are slidably connected through a protrusion and groove 402c structure, and the lower adjusting ear 502 is rotatably sleeved on the inner side of the lower insertion pin 503, so that the lower mold base 102, which is sleeved on the outer side of the lower insertion pin 503, can rotate with the lower insertion pin 503 as the axis.

[0057] The upper mold adjustment component 400 and the lower mold adjustment component 500 are coaxially arranged. Through the above scheme, the angle of the two mold bodies 100 connected by the upper mold adjustment component 400 and the lower mold adjustment component 500 can be adjusted.

[0058] When the synchronizing component 600 can move in the first direction, the upper insertion pin 403 can lock the upper positioning ear 401 and the upper adjusting ear 402, and the lower insertion pin 503 can lock the lower positioning ear 501 and the lower adjusting ear 502. Before using the hydraulic press to press the mold body 100, the connection between the synchronizing component 600 and the upper mold base 101 and the lower mold base 102 is released, so that the synchronizing component 600 moves in the first direction. At this time, the angles of the two upper mold bases 101 are locked, and the angles of the two lower mold bases 102 are locked, so that the angle between the two upper mold bases 101 and the angle between the two lower mold bases 102 can be the same.

[0059] Synchronization component 600 includes: an upper synchronization ear 601 fixed to the upper mold base 101; a lower synchronization cylinder 602 fixed to the lower mold base 102; a synchronization shaft 603 slidingly passing through the upper synchronization ear 601 and the lower synchronization cylinder 602, the end of which can be locked with the lower synchronization cylinder 602; and a first elastic member 604 abutting against the synchronization shaft 603 and capable of pushing the synchronization shaft 603 to move in a first direction. The upper synchronization ear 601, the lower positioning ear 501, and the lower positioning ear 501 are coaxial. A locking block 603a is integrally formed at the end of the synchronous shaft 603 near the lower synchronous cylinder 602. A U-shaped locking groove 602a is provided on the outer side of the lower synchronous cylinder 602. The synchronous shaft 603 can press the first elastic member 604, and the locking block 603a enters the inner side of the locking groove 602a. The first elastic member 604 can apply a pushing force to the synchronous shaft 603 in a first direction, so that the locking block 603a is stably positioned inside the locking groove 602a.

[0060] Furthermore, the two ends of the locking groove 602a are an open end 602a-1 and a locking end 602a-2, respectively, and are connected by a connecting section 602a-3. The included angle between the locking end 602a-2 and the open end 602a-1 is 60 degrees. A shifting slider is integrally formed on the outer side of the synchronous shaft 603 and at the corresponding position of the locking block 603a. A first guide groove 601a and a second guide groove 601b are formed on the upper synchronous ear 601. When the locking block 603a is located inside the locking end 602a-2, the shifting slider is located in the first guide groove 602a-1. Inside 1a, when the synchronous shaft 603 is pressed down, the locking block 603a can reach the connecting section 602a-3. At this time, the shifting slider can disengage from the inside of the first guide groove 601a. ​​When the synchronous shaft 603 is rotated, the shifting slider can reach the opening end 602a-1. The position of the shifting slider corresponds to the position of the second guide groove 601b. At this time, the first elastic element 604 can push the synchronous shaft 603 away from the lower synchronous cylinder 602. When the locking block 603a is located inside the locking end 602a-2, the synchronous shaft 603 cannot rotate relative to the upper synchronous ear 601.

[0061] Synchronous shaft 603 and upper synchronous ear 601 are slidably connected by a slider-type and groove-type 402c structure, so that upper mold base 101 and lower mold base 102 can be synchronized, avoiding the problem of misalignment between upper mold base 101 and lower mold base 102.

[0062] The upper positioning ear 401 includes a first secondary ear 401a and a second secondary ear 401b with a gap. The second secondary ear 401b has an upper positioning hole 401c. The upper adjusting ear 402 has a circumferentially distributed set of upper adjusting holes 402a. The upper insertion pin 403 has an upper locking pin 403a that can be inserted into both the set of upper adjusting holes 402a and the upper positioning hole 401c simultaneously. When the synchronous shaft 603 moves in the first direction, it can push the upper locking pin 403a into the inner side of the set of upper adjusting holes 402a and the upper positioning hole 401c. The lower positioning ear 501 includes a third secondary ear 501a and a fourth secondary ear 501b with a gap. The fourth secondary ear 501b has a lower positioning hole 501c.

[0063] The lower adjusting ear 502 has a circumferentially distributed lower adjusting hole group 502a; the lower insert pin 503 is fixed with a lower locking post 503a, and the outer side of the lower insert pin 503 is fixedly sleeved with an abutment ring 503b. The outer side of the lower insert pin 503 is sleeved between the abutment ring 503b and the fourth auxiliary ear 501b. When the synchronous shaft 603 moves in the first direction, the second elastic member 503c can push the lower insert pin 503 to move in the first direction, and the lower locking post 503a can be inserted into the inner side of the lower adjusting hole group 502a and the lower positioning hole 501c at the same time.

[0064] The upper adjusting hole group 402a is positioned to correspond to the upper positioning hole 401c, and the lower adjusting hole group 502a is positioned to correspond to the lower positioning hole 501c. The upper locking pin 403a is inserted into the inner side of both the upper adjusting hole group 402a and the upper positioning hole 401c, which can lock the angle between the two upper mold bases 101. The lower locking pin 503a is inserted into the inner side of both the lower adjusting hole group 502a and the lower positioning hole 501c, which can lock the angle between the two lower mold bases 102.

[0065] The rest of the structure is the same as in Example 2.

[0066] Operation process: In the natural state, the locking block 603a is located inside the locking groove 602a, the lower end of the synchronous shaft 603 abuts against the lower insertion pin 503, and the lower locking pin 503a disengages from the lower adjusting hole group 502a and the lower positioning hole 501c.

[0067] Under the influence of gravity, the upper locking pin 403a remains detached from the upper adjusting hole group 402a and the upper positioning hole 401c.

[0068] After the locking block 603a is disengaged from the inside of the locking groove 602a, the synchronous shaft 603 is pushed to move in the first direction under the action of the first elastic member 604. The upper end of the synchronous shaft 603 abuts against the upper insertion pin 403. The upper insertion pin 403 drives the upper locking post 403a to enter the inside of the upper adjusting hole group 402a and the upper positioning hole 401c, thus completing the locking of the two upper mold bases 101.

[0069] Furthermore, the resistance of the lower end of the synchronous shaft 603 to the lower insertion pin 503 disappears. Under the action of the second elastic element 503c, the lower insertion pin 503 is pushed to move in the first direction. The lower insertion pin 503 drives the lower locking pin 503a to enter the inner side of the lower adjustment hole and the lower positioning hole 501c, thus completing the locking of the two lower mold bases 102.

[0070] Through the above steps, the angle between two or more mold bodies 100 can be adjusted synchronously according to the different concave hole distribution requirements of automotive structural parts. After the two or more lower mold bases 102 are adjusted, they can keep the same angle with the multiple upper mold bases 101 and correspond one-to-one.

[0071] Example 4

[0072] Reference Figure 8 , Figure 10 , Figure 11 and Figure 12This embodiment differs from the above embodiments in that, in order to simultaneously adjust the distance between the two mold bodies 100, the flexible recess forming mold of this automotive structural component also includes a distance adjustment component 700 disposed between the upper adjustment ear 402 and the upper mold base 101. The upper adjustment ear 402 and the upper mold base 101 are slidably connected. The upper adjustment ear 402 can rotate around the upper insertion pin 403 as the axis to achieve the effect of adjusting the angle between the two connected mold bodies 100. The distance between the two molds can be adjusted by adjusting the length of the extension of the upper adjustment ear 402.

[0073] The distance adjustment component 700 can lock the upper adjustment ear 402 and the upper mold base 101, so that the distance between the two mold bodies 100 after adjustment can be locked. The distance adjustment component 700 includes a positioning rack 701, fixed on the upper mold base 101; a transmission member 702, slidably disposed on the upper adjustment ear 402; and a locking member 703, disposed on the side wall of the upper adjustment ear 402, which can engage with the positioning rack 701. When the upper insertion pin 403 moves in the first direction, it can push the transmission member 702 to press the locking member 703. When the locking member 703 is pressed, it engages with the positioning rack 701, thereby locking the upper adjustment ear 402 and the upper mold base 101.

[0074] The sliding connection between the upper adjusting ear 402 and the upper mold base 101 is achieved by opening an installation groove on the upper mold base 101, matching the size of the upper adjusting ear 402 with the size of the installation groove, allowing the upper adjusting ear 402 to slide within the installation groove, and having two positioning racks 701 located on the two side walls of the installation groove.

[0075] The lower adjusting ear 502 and the lower mold base 102 are slidably connected. A distance adjusting component 700 is also provided between the lower adjusting ear 502 and the lower mold base 102. The lower adjusting ear 502 and the lower mold base 102 can also be locked in position by the distance adjusting component 700.

[0076] Specifically, the upper adjustment ear 402 has a cavity 402b on its inner side, and a groove 402c coaxial with the upper insertion pin 403 is provided on the upper adjustment ear 402. The groove 402c and the cavity 402b are in a communication state.

[0077] The conductive member 702 includes a sliding post 702a slidably disposed inside the cavity 402b, a force-receiving block 702b disposed at the end of the sliding post 702a and extending into the groove 402c, a third elastic member 702c abutting against the sliding post 702a, and an abutting body 702d disposed on the sliding post 702a away from the force-receiving block 702b. The sliding post 702a is capable of sliding within the cavity 402b, and a section is formed at the middle of the cavity 402b. The middle section 402b-1 has an inner diameter larger than that of the cavity 402b. A retaining plate 702a-1 is fixed on the outer side of the sliding column 702a. The retaining plate 702a-1 and the third elastic member 702c abut against each other. The third elastic member 702c applies a pushing force to the sliding column 702a in the direction of the groove 402c through the retaining plate 702a-1, so that the force-bearing block 702b is kept inside the groove 402c.

[0078] The groove 402c is circular. A frustum-shaped push cone component M, which is adapted to the diameter of the groove 402c, is integrally formed on the outside of the upper insertion pin 403. When the upper insertion pin 403 moves in the first direction, the push cone component M enters the inside of the groove 402c and presses the force block 702b, so that the force block 702b pushes the sliding column 702a, and the sliding column 702a pushes the abutment 702d to press the locking component 703.

[0079] The locking component 703 includes a through post 703a that slides through the upper adjusting ear 402, a locking block 703b located at one end of the through post 703a, and a pressing block 703c located at the other end of the through post 703a and corresponding to the contact body 702d.

[0080] The locking member 703 also includes a return spring 703d that abuts against the pressing block 703c.

[0081] When the sliding column 702a pushes the abutment to press the locking member 703, the abutment will push the pressing block 703c. Due to the inclined surface setting at the contact position between the abutment and the pressing block 703c, the pressing block 703c can push the through column 703a, and the through column 703a pushes the locking block 703b to move towards the positioning rack 701. Then the locking block 703b and the positioning rack 701 are locked together, achieving the effect of positioning the upper mold base 101 and the upper adjusting ear 402.

[0082] Among them, the first elastic element 604, the second elastic element 503c, and the third elastic element 702c can all be spring structures.

[0083] Furthermore, the positioning methods of the lower mold base 102 and the lower adjusting ear 502 are the same as those of the upper mold base 101 and the upper adjusting ear 402, and will not be described in detail here.

[0084] Furthermore, when the two mold bodies 100 are connected and adjusted, the top surfaces of the two upper mold bases 101 are on the same horizontal plane, and the upper adjustment ear 402 on one upper mold base 101 can support the first auxiliary ear 401a on the other upper mold base 101.

[0085] Therefore, when several mold bodies 100 are connected, they can form a mold group 1000. Only auxiliary mold frames 3000 need to be set at both ends of the mold group 1000. The main function of the mold frame 3000 is to connect the upper mold base 101 and the lower mold base 102 in the two mold bodies 100 at both ends of the mold group 1000.

[0086] The mold frame 3000 and the mold assembly 1000 are detachably connected. After the positional relationship between multiple mold bodies 100 in a mold assembly 1000 is determined, the mold frame 3000 is removed to obtain multiple upper mold bases 101 and lower mold bases 102 with the same positional relationship.

[0087] When forming concave holes in automotive structural parts using this mold base assembly, the upper mold base 101 assembly can be fixed to the lower pressing part of the hydraulic press, and the lower mold base 102 assembly can be fixed to the hydraulic table. The automotive structural parts are located between the two. By driving the upper mold base 101 assembly to press down through the hydraulic press, multiple concave holes can be formed on the automotive structural parts at one time.

[0088] The rest of the structure is the same as in Example 3.

[0089] Operation process: The upper adjusting ear 402 can rotate around the upper insert pin 403 as the axis to adjust the angle between the two connected mold bodies 100. The distance between the two molds can be adjusted by adjusting the length of the upper adjusting ear 402. This allows the angle and distance between the multiple mold bodies 100 in the mold group 1000 to be adjusted, thereby adapting to the concave hole forming requirements of different automotive structural parts.
