[0002] In a narrow sense, automotive molds refer to all the molds used to stamp all the stamped parts of a car body. This is also known as "automobile body stamping molds." Examples include roof flanging molds and crossbeam reinforcement plate forming molds.

[0003] The existing patent, titled "A Fender Side-Tilting Mold" (patent application number: 201510077371.4), includes an upper mold base and a lower mold base. A punch is mounted on the lower mold base, a pressure core is mounted above the punch, and a side-tilting mechanism is mounted beside the punch. The side-tilting mechanism includes a movable module that is horizontally rotatable and fixed on the lower mold base. A first drive mechanism is connected to the movable module. The movable module is composed of a semi-circular plate arranged vertically. The circular plate has a support surface, a side wall surface, and a forming surface. The angle between the forming surface and the side wall surface is complementary to the side-tilting angle of the wheel arch mounting hole. The upper part of the movable module is a side-tilting die head. During operation, a cylinder 36 is required to drive the circular plate 30 to rotate, adding a power component and increasing the overall cost of the mold. To solve this technical problem, a side-tilting mechanism for automotive molds is proposed. Summary of the Invention

[0011] As a further embodiment of the present invention, an automatic molding holding mechanism is also provided between the second mating molded part and the first mating molded part.

[0012] As a further embodiment of the present invention: the automatic holding mechanism includes a first locking block fixedly mounted on the driving part and a transmission rod disposed on the second mating molded part. The transmission rod is rotatably mounted on the second mating molded part, and the end of the transmission rod is provided with a second locking member for engaging and locking with the first locking block; it also includes an unlocking component for releasing the lock between the first locking block and the second locking member.

The second vertical surface is connected to the upper end of the third inclined surface, and the first vertical surface is connected to the upper end of the first inclined surface.

[0013] As a further embodiment of the present invention: there are two second locking members, which are arranged on both sides of the first locking block. Each of the two second locking members is provided with a locking telescopic rod on the side of the first locking block. The locking telescopic rod is used to engage in the locking groove of the adjacent side wall of the first locking block.

The second mating forming part and the driving part move closer to each other to perform a flanging operation on the leaf plate. This solves the problem that the prior art requires a separate power mechanism, which increases the cost of the equipment. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1

[0030] Please see Figures 1-2The present invention provides a side-tilting mechanism for an automobile mold, comprising: an upper seat 10 and a base 20; a pressure core 11 is provided on the upper seat 10, the pressure core 11 is mounted on the upper seat 10 via a telescopic cylinder 13, the two ends of the telescopic cylinder 13 are respectively fixedly mounted on the upper seat 10 and the pressure core 11; the telescopic cylinder 13 is used to drive the pressure core 11 to rise and fall; a punch 21 for cooperating with the pressure core 11 is provided on the base 20; a side-tilting mechanism 30 is also provided between the upper seat 10 and the base 20; the side-tilting mechanism 30 includes a driving pressure block 31, a first mating forming part 32 and a second mating forming part 33, the driving pressure block 31 is fixedly mounted on the upper seat 10; the first mating forming part 32 and the second mating forming part 33 are horizontally elastically slidably disposed on the base 20, and the driving pressure block 31 is used to drive the first mating forming part 32 when the upper seat 10 descends. The first molding component 32 and the second mating molding component 33 perform sidewall flanging on the fender. Both the first mating molding component 32 and the second mating molding component 33 are horizontally and elastically slidably mounted on the base 20. The first mating molding component 32 includes a molding part 321, a driving part 322, and a connecting part 323. The molding part 321 and the driving part 322 are respectively fixedly installed at both ends of the connecting part 323. The connecting part 323 is horizontally positioned. The driving part 322 is used to cooperate with the second mating molding component 33 to perform sidewall flanging on the fender. The driving pressure block 31 has a first inclined surface 313 and a second inclined surface 314 on both sides. The molding part 321 has a third inclined surface 324, and the second mating molding component 33 has a fourth inclined surface 331. The first inclined surface 313 cooperates with the molding part 321, and the second inclined surface 314 cooperates with the fourth inclined surface 331. The second mating molding component 33 is positioned between the driving part 322 and the molding part 321. The first mating molding component 32 has a U-shaped structure.

[0031] Specifically, during use, the blade is first placed on the punch 21, and then the upper seat 10 descends to drive the pressure core 11 to form the blade. After forming, the telescopic cylinder 13 retracts, and the upper seat 10 continues to descend. The first inclined surface 313 first abuts against the third inclined surface 324, causing the forming part 321 to drive the driving part 322 to slide to the right through the connecting part 323. At the same time, during the descent, the second inclined surface 314 contacts the fourth inclined surface 331, causing the second mating forming part 33 to slide to the left. The second mating forming part 33 and the driving part 322 move closer to each other to perform a flanging operation on the blade. This solves the problem of the existing technology requiring a separate power mechanism, which increases the cost of the equipment.

[0032] It should be noted that the first mating molding part 32 and the second mating molding part 33 are slidably disposed on the base 20, which is prior art and will not be described in detail here. The fourth inclined surface 331 is disposed below the second inclined surface 314, and the third inclined surface 324 is disposed below the first inclined surface 313.

[0033] like Figure 1-4 As shown, in a preferred embodiment of the present invention, in the prior art, during the molding process, the pressure core 11 and the punch 21 are held together for a period of time. While the pressure core 11 and the punch 21 are being held together, the upper seat 10 continues to descend. At this time, the side-flipping mechanism 30 flips the object to the side. The side-flipping also needs to be held for a period of time during the processing to ensure molding and avoid deformation. This increases the molding time and reduces work efficiency. Therefore, an automatic molding holding mechanism is also provided between the second mating molding part 33 and the first mating molding part 32.

[0034] like Figure 1-4 As shown, in a preferred embodiment of the present invention, the automatic holding mechanism includes a first locking block 35 fixedly mounted on the drive unit 322 and a transmission rod 38 disposed on the second mating molding part 33. The transmission rod 38 is rotatably mounted on the second mating molding part 33, and the end of the transmission rod 38 is provided with a second locking member 39 for engaging and locking with the first locking block 35. It also includes an unlocking component for releasing the lock between the first locking block 35 and the second locking member 39. The unlocking component is disposed on the second mating molding part 33 and is used to release the lock when the second mating molding part 33 returns. The automatic holding mechanism also includes a first vertical surface 317 disposed on the drive pressure block 31 and a second vertical surface 325 disposed on the molding part 321. The second vertical surface 325 is connected to the upper end of the third inclined surface 324, and the first vertical surface 317 is connected to the upper end of the first inclined surface 313. Specifically, after the second mating molding part 33 and the drive part 322 have completed their approach to form the fender, the second locking part 39 locks onto the first locking block 35. At the same time, the drive pressure block 31 moves upward with the upper seat 10. When the upward movement is almost complete, the drive unlocking component releases the lock between the second locking part 39 and the first locking block 35. Simultaneously, the first vertical surface 317 contacts the second vertical surface 325, so that the first mating molding part 32 is maintained in the molding position, and the second mating molding part 33 and the drive part 322 return to their initial positions under their own elasticity. In this way, the upper seat 10 is used to maintain the molding during the rising period, reducing the side-tipping holding time and further improving work efficiency.

[0035] To ensure stable locking of the first locking block 35 by the second locking member 39, two second locking members 39 are arranged on both sides of the first locking block 35. Each of the two second locking members 39 has a locking telescopic rod 391 on the side closest to the first locking block 35. The locking telescopic rod 391 engages with a locking groove 351 on the adjacent sidewall of the first locking block 35. The locking groove 351 has a right-angled triangular cross-section, with the right angle on the outer side. One right-angled side of the locking groove 351 is horizontal, and the other right-angled side is vertical.

[0036] In a preferred embodiment of the present invention, guide ramps are provided on both sides of the first locking block 35 near the end of the second mating molded member 33. The guide ramps are provided to allow the locking telescopic rod 391 to retract into the second locking member 39 as the second locking member 39 moves closer to the first locking block 35 along with the second mating molded member 33. Then, it continues to move to the right with the second mating molded member 33 before it can be inserted into the locking groove 351.

[0037] The first locking block 35 has multiple locking grooves 351 on each side wall, which facilitates locking when forming fenders of different thicknesses. The first locking block 35 can be a directional structure.

[0038] like Figure 3-6 As shown, in a preferred embodiment of the present invention, the unlocking assembly includes an elastic telescopic rod 37 elastically rotatably mounted on the second mating molded part 33 and a driving assembly fixedly mounted on the bottom of the driving pressure block 31. The elastic telescopic rod 37 is connected to the transmission rod 38. The driving assembly is used to drive the elastic telescopic rod 37 to rotate when the driving pressure block 31 rises with the upper seat 10. The elastic telescopic rod 37 drives the transmission rod 38 to rotate, so that the locking telescopic rod 391 on the second locking member 39 leaves the locking groove 351, thereby releasing the mutual locking between the second mating molded part 33 and the driving part 322.

[0039] like Figure 3-6 As shown, in a preferred embodiment of the present invention, the driving assembly includes a mounting rod 311 fixedly mounted on the second mating molding part 33, a driving member 312 disposed on the mounting rod 311, and a driving mating member 36 fixedly mounted on the end of the elastic telescopic rod 37. When the mounting rod 311 moves upward with the driving pressure block 31, the driving member 312 moves upward with the mounting rod 311. When the driving member 312 passes the driving mating member 36, it drives the driving mating member 36 to drive the elastic telescopic rod 37 to rotate, thus providing power for the rotation of the elastic telescopic rod 37.

[0040] The driving engagement component 36 is a gear structure, and the driving component 312 is a rack structure, so that the driving component 312 can drive the driving engagement component 36 to rotate.

[0041] It should be noted that initially, when the drive member 312 descends with the mounting rod 311, the drive mating member 36 is not on the trajectory of the drive member 312. Therefore, the drive member 312 will not pass through the drive mating member 36, and thus will not drive the drive mating member 36 to reverse. Even if the drive member 312 contacts the drive mating member 36 during its descent, the drive mating member 36 can be configured as a one-way ratchet mechanism. Thus, when the drive member 312 contacts the drive mating member 36 during its descent, it cannot drive the elastic telescopic rod 37 to rotate, ensuring the locking relationship between the second locking member 39 and the first locking block 35.

[0042] like Figure 3-6 As shown, in a preferred embodiment of the present invention, the elastic telescopic rod 37 includes a sleeve rod 372 and a second slide rod 371. One end of the second slide rod 371 is elastically slidably disposed in the mounting hole at the end of the sleeve rod 372 along the horizontal direction. The sleeve rod 372 is elastically rotatably mounted on the second mating molded part 33.

[0043] Specifically, the second slide rod 371 has sliders 375 on both side walls near the end of the sleeve rod 372. These sliders 375 are slidably disposed in adjacent guide grooves 374, which are located on the side walls of the mounting hole. The second slide rod 371 is fixedly mounted on one end of the second elastic member 373, and the other end of the second elastic member 373 is fixedly mounted inside the mounting hole. This achieves the elastic sliding installation of the second slide rod 371. The second elastic member 373 can be a coil spring.

[0044] In a preferred embodiment of the present invention, a third elastic element 376 is sleeved on the outer side of the guide groove 374, and the two ends of the third elastic element 376 are respectively mounted on the second mating molding part 33 and the guide groove 374. The third elastic element 376 can be a torsion spring. The third elastic element 376 is a restoring spring, which enables the guide groove 374 to maintain its initial position.

[0045] In a preferred embodiment of the present invention, a first gear 377 is fixedly sleeved at the end of the guide groove 374, and a second gear 381 is provided on both sides of the first gear 377. The two second gears 381 are respectively fixedly sleeved on the transmission rods 38 at adjacent positions. Thus, when the guide groove 374 rotates, the first gear 377 can drive the two second gears 381 to drive the two transmission rods 38 to rotate simultaneously.

[0046] like Figure 7As shown, in a preferred embodiment of the present invention, in order to maintain the deflection time of the elastic telescopic rod 37 for a longer period, and to allow the transmission rod 38 to drive the second locking member 39 to deflect for a longer period, so that the second locking member 39 can be completely separated from the first locking block 35, the driving member 312 is elastically slidably mounted on the mounting rod 311 in the vertical direction; and the teeth on the driving member 312 are elastically rotatably mounted. Specifically, the driving member 312 has a first sliding rod 315 fixedly mounted at both ends, and the first sliding rod 315 is elastically slidably mounted on the mounting rod 311. A first elastic member 316 is also sleeved on the outside of the mounting rod 311, and the two ends of the first elastic member 316 are respectively fixedly mounted on the driving member 312 and the mounting rod 311, thus realizing the elastic sliding setting of the driving member 312. When the elastic telescopic rod 37 cannot rotate, the driving member 312 moves downward under the action of the driving engagement member 36, maintaining engagement at one end. When it approaches the elastic rotation limit of the teeth on the driving member 312, the teeth on the driving member 312 will deflect, releasing the engagement between the driving engagement member 36 and the driving member 312. The teeth on the driving member 312 are rotatably mounted via a torsion spring.

[0047] In a preferred embodiment of the present invention, the first mating molded part 32 is elastically mounted on the base 20 via a transmission rod 38, with both ends of the transmission rod 38 fixedly mounted on the molding part 321 and the base 20, respectively. The second mating molded part 33 is elastically mounted on the base 20 via a first restoring elastic member 34, with both ends of the first restoring elastic member 34 fixedly mounted on the second mating molded part 33 and the base 20, respectively. First sliders may be provided on both sides of the second mating molded part 33, and the first sliders are horizontally slidably disposed in a first horizontal groove on the side wall of the base 20. Second sliders may also be provided on both sides of the first mating molded part 32, and the second sliders are horizontally slidably disposed in a second horizontal groove on the side wall of the base 20. The specific positions of the first and second sliders are prior art and will not be described in detail here.

[0048] The working principle of this invention is:

[0049] In operation, the fender is first placed on the punch 21. Then, the upper seat 10 descends, driving the pressure core 11 to form the fender. After forming, the telescopic cylinder 13 retracts, and the fender is in the forming holding position. At the same time, the upper seat 10 continues to descend, and the first inclined surface 313 first abuts against the third inclined surface 324, causing the forming part 321 to drive the driving part 322 to slide to the right through the connecting part 323. Simultaneously, during the descent, the second inclined surface 314 contacts the fourth inclined surface 331, causing the second mating forming part 33 to slide to the left. The second mating forming part 33 and the driving part 322 move closer to each other to perform a flanging operation on the fender. This solves the problem of existing technologies requiring a separate power mechanism, which increases the cost of the equipment. At the same time, as the second mating forming part 33 moves closer to the driving part 322, the second locking part 39 drives the locking telescopic rod 391 to move closer to the first locking block 35. The locking telescopic rod 391 slides into the corresponding locking groove 351 through the guide ramp, and then the second mating forming part... The second mating molding part 33 is limited by the drive unit 322; then the upper seat 10 returns, driving the pressure core 11 and the drive pressure block 31 to move upward. At this time, due to the action of the second locking part 39 and the first locking block 35, the second mating molding part 33 and the drive unit 322 are kept locked, so that the side-tilting operation is kept in the holding state. Then, when the drive pressure block 31 rises to one end height with the upper seat 10, the drive part 312 engages with the drive mating part 36. At this time, the first vertical surface 317 is still in contact with the second vertical surface 325, so that the first mating molding part 32 is kept in the molding position. However, the locking telescopic rod 391 disengages from the locking groove 351, and the drive pressure block 31 moves upward a certain distance. At the same time, under the elastic action, the second mating molding part 33 slides to the right, so that the locking telescopic rod 391 and the locking groove 351 completely disengage from the overlapping position. Thus, when the first vertical surface 317 disengages from the second vertical surface 325, the first mating molding part 32 can return to the initial position under the elastic action.
