Description

Technical Field

[0001] This utility model relates to the field of automotive mold technology, specifically to a rotary side shaping mold for automotive door outer panels. Background Technology

[0002] With the diversification of automotive consumer demand, the automotive upgrade cycle is constantly shortening, leading to an increase in the frequency of mold development. This has resulted in increased mold investment costs and a continuous compression of automotive mold development cycles. Consequently, research on low-cost, high-quality stamping side forming mold technology is receiving increasing attention. Currently, the outer and inner panels of a car door are connected to form an integral door structure through methods such as edge banding, welding, bonding, or riveting. The edge banding surface of the outer door panel is first formed by the side forming mold and then by the edge banding mold or a rolling robot.

[0003] Existing methods primarily achieve side flanging through the horizontal linear motion of the die slider. For example, a wedge-driven die expands along a guide rail to complete the forming process, and then a spring or cylinder drives the slider to retract linearly to remove the material. This type of mechanism has several problems: First, it requires multiple guide plates and multiple power sources working together inside the mold, resulting in a complex mold structure, large space occupation, and the interconnection of multiple components is prone to cumulative errors or collision interference, affecting the accuracy of the side flanging and requiring extensive adjustments by operators. Second, during material removal, the die needs to retract a considerable distance linearly to avoid the part, which is difficult to meet the high-frequency development requirements of automotive molds for low cost and high efficiency, affecting part removal efficiency and increasing mold costs.

It features a simple structure, ease of implementation, and low cost, solving the problems of complex overall structure, large space occupation, and low part removal efficiency associated with existing side forming molds that use linear movement for material ejection. The main technical solution adopted is as follows:

[0005] A rotary side-shaping mold for an automobile door outer panel includes an upper mold base with a pressing device and a wedge block arranged side by side; a lower mold base with a cavity containing a tilting table; the front and rear sides of the tilting table are rotatably connected to the lower mold base via two coaxially arranged rotating shaft assemblies, allowing the tilting table to be suspended and installed within the cavity; the lower mold base also has a support part for supporting the automobile door outer panel on the side of the cavity, the support part being located in the radial direction of the coaxial axis of the two rotating shaft assemblies; drive mechanisms are formed on the left and right sides of the tilting table. The device includes a driving part and a clamping part, with the clamping part located adjacent to the support part; an angle limiting mechanism located in the cavity and below the side of the flipping table, used to push the flipping table to rotate to a certain angle so that the driving part and the clamping part form a height difference; when the upper mold base moves downward, it acts on the driving part to drive the flipping table to rotate, so that the working surfaces of the clamping part and the support part form a continuous transition pressing mating surface, which cooperates with the presser to press the outer panel of the car door, so that the wedge block moves in a misaligned manner relative to the pressing mating surface, which can turn the outer panel of the car door to the side and shape it.

[0006] Preferably, the upper mold base is provided with a guiding mechanism, which includes a first spring seat and a first pulley disposed in the first spring seat. When the upper mold base moves downward relative to the lower mold base, the upper mold base acts on the driving part through the first pulley to form a rolling contact engagement and drive the tilting table to rotate.

[0007] Preferably, the angle limiting mechanism includes a second spring seat and a second pulley disposed in the second spring seat. The second pulley applies a vertically upward force to the bottom of the tilting table under the action of the second spring seat, so as to push the tilting table to rotate to a certain angle.

[0008] Preferably, the first pulley and the second pulley are arranged in opposite directions.

[0009] Preferably, at least one anti-deflection mechanism is also provided in the cavity of the lower mold base. The anti-deflection mechanism includes a slide table located in the middle of the bottom wall of the cavity and a sliding block located at the bottom of the flipping table. When the flipping table rotates in the cavity, the sliding block guides and slides within the slide table.

[0010] Preferably, the anti-deflection mechanism is provided in three sets, and the three sets of anti-deflection mechanisms are arranged along the length direction of the flipping table.

[0011] Preferably, the rotating shaft assembly includes a rotating shaft and a fixed platform disposed on the lower mold base. One end of the rotating shaft is engaged with a side locking hole of the flipping platform, and the other end is inserted into a through hole of the fixed platform to form a rotatable connection. When the flipping platform rotates, the rotating shaft rotates synchronously within the fixed platform.

[0012] Preferably, the rotating shaft assembly further includes a wear-resistant sleeve disposed in the through hole of the fixed platform, and the rotating shaft is inserted into the wear-resistant sleeve and rotatably connected to the through hole of the fixed platform.

[0013] Preferably, the rotating shaft includes an integrally formed long shaft portion and a rectangular connecting portion. The long shaft portion is inserted into the wear-resistant sleeve of the fixed platform, and the rectangular connecting portion is inserted into the side slot of the tilting platform for locking and fixing.

[0014] Preferably, the flipping platform is provided with a wedge base block. When the upper mold base moves downward relative to the lower mold base, the wedge cutter block slides on the wedge base block and is misaligned with the clamping mating surface.

[0015] As can be seen from the above description of this utility model, compared with the prior art, this utility model has the following beneficial effects:

[0016] (1) This utility model provides a rotary side forming mold for automotive door panels. It has a simple structure, is easy to implement, and is inexpensive. It solves the problems of complex overall structure, large space occupation, and low part removal efficiency caused by the linear movement material removal of existing side forming molds. In this utility model, the rotating table is suspended in the cavity of the lower mold base by a rotating shaft assembly. When the upper mold base moves downward, it drives the rotating table to rotate, so that the clamping part and the supporting part form a continuous pressing mating surface. The pressing mating surface cooperates with the misaligned movement of the wedge block to complete the side flanging action. During the return stroke, the rotating table will automatically rotate in the opposite direction under the action of the angle limiting mechanism to realize the material removal. Compared with the simple linear motion of the existing die, the composite motion mode of linear drive and rotation angle adjustment replaces the linear advance and retreat of the die slider with the rotation of the rotating table, which reduces the number of guide plates and pressure source configuration. At the same time, the rotary material removal method does not require a large space for the die linear retreat to perform a large stroke linear retreat, which significantly simplifies the mold structure, improves accuracy, reduces costs, shortens the part removal time, and greatly reduces the mold development cost. Therefore, this structure replaces the traditional linear unloading motion with the rotational motion of the flipping table, which significantly simplifies the mold structure, reduces the number of pressure sources and guide plates, and improves motion accuracy and stability through rolling contact and anti-deflection design, so as to achieve low-cost, high-precision production of automotive door outer panel side flanging and effectively improve production efficiency.

[0017] (2) In this technical solution, the drive unit and clamping unit on the left and right sides of the turning table, the two rotating shaft assemblies coaxially arranged on the front and rear sides of the turning table, and the angle limiting mechanism located below the side of the turning table, the orientation of the above key structures can ensure that the turning table can realize reset and flip to realize feeding and unloading, and can effectively save space and prevent interference between the various structures.

[0018] (3) In this technical solution, the rolling contact between the first pulley and the drive unit replaces the traditional rigid contact friction, reducing the loss of driving force, and the mixed wheel structure can make the tilting table rotate more smoothly; while the structure of the spring seat can effectively provide a buffering effect, avoid rigid impact, and improve the stability of the mechanism operation.

[0019] (4) In this technical solution, the elastic push of the second spring seat can accurately control the rotation angle of the flipping table, ensure the position accuracy of the side flipping edge, reduce mechanical wear and extend the service life of the mechanism; secondly, the sliding contact method of the second pulley can also ensure that the flipping table will not be interfered with during rotation and the rotation is smoother.

[0020] (5) In this technical solution, the first pulley and the second pulley are set in opposite directions of movement. The force formed on both sides of the turning table can effectively offset the lateral force during the rotation process, avoid the turning table from tilting due to uneven force, ensure that it rotates evenly around the axis of rotation, avoid rotation jamming and sudden jumping, improve the continuity and stability of movement, and ensure that the clamping part of the turning table can accurately complete the transition with the working surface of the material support part.

[0021] (6) In this technical solution, the anti-deflection mechanism set in the cavity of the lower mold base is guided by the sliding block at the bottom of the slide table and the flipping table. This can constrain the lateral displacement when the flipping table rotates, ensure that the clamping mating surfaces of the clamping part and the support part are accurately aligned, avoid the positioning deviation of the door outer panel parts caused by the tilt of the flipping table, and ensure the consistency of the side flange accuracy.

[0022] (7) In this technical solution, the anti-deflection mechanism is provided in two sets arranged along the length of the tilting table, so as to ensure that the tilting table maintains a certain balance when it tilts. Attached Figure Description

[0041] Please see Figures 1 to 10 .

[0042] This embodiment provides a rotary side-forming mold for automotive door outer panels. Its structure is simple, easy to implement, and low-cost, solving the problems of complex overall structure, large space occupation, and low part removal efficiency associated with existing side-forming molds that use linear movement for material ejection. The rotary side-forming mold in this embodiment is mainly suitable for processing automotive door outer panels Y. (See [link to relevant documentation]). Figure 1 The rotary side-shaping mold includes an upper mold base 1 and a lower mold base 2, wherein,

[0043] Upper mold base 1, see Figure 2 and Figure 3 It is equipped with a pressing device 11 and a wedge block 12 arranged side by side; the pressing device 11 is mainly connected to the upper mold base 1 by a nitrogen spring;

[0044] Lower mold base 2, see Figure 4It has a rectangular cavity 21, and a tilting platform 3 is built into the cavity 21. The front and rear sides of the tilting platform 3 are rotatably connected to the lower mold base 2 through two coaxially arranged rotating shaft 41 assemblies, so that the tilting platform 3 can be suspended and installed in the cavity 21. The lower mold base 2 is also provided with a support part 22 for supporting the outer panel Y of the car door on the side of the cavity 21. The support part 22 is located in the radial direction of the coaxial line of the two rotating shaft 41 assemblies. A driving part 31 and a clamping part 32 are formed on the left and right sides of the tilting platform 3, respectively. The clamping part 32 is arranged adjacent to the support part 22. In this embodiment, the front and rear, left and right positions of the tilting platform 3 represent four different positions.

[0045] Angle limiting mechanism 5, see Figure 4 It is located inside the cavity 21 and below the side of the tilting table 3, see [reference]. Figure 9 It is used to push the tilting table 3 to rotate to a certain angle so that the drive part 31 and the clamping part 32 form a height difference;

[0046] When the upper mold base 1 moves downwards, see Figure 10 Its action on the drive unit 31 drives the tilting table 3 to rotate, so that the working surfaces of the clamping part 32 and the support part 22 form a continuous transition pressing mating surface, which cooperates with the presser 11 to press the outer panel Y of the car door, so that the oblique wedge block 12 can move in a misaligned manner relative to the pressing mating surface to tilt and shape the outer panel Y of the car door.

[0047] In this embodiment, see Figure 9 The upper mold base 1 is provided with a guiding mechanism 6, which includes a first spring seat 61 and a first pulley 62 disposed within the first spring seat 61. When the upper mold base 1 moves downward relative to the lower mold base 2, the upper mold base 1 acts on the drive unit 31 through the first pulley 62 to form a rolling contact engagement, thereby driving the tilting table 3 to rotate. In this embodiment, the first spring seat 61 and the first pulley 62 are existing structures. A common spring or a nitrogen spring can be disposed within the first spring seat 61. The first pulley 62 is fitted within the first spring seat 61 and moves towards the lower mold base 2 under the action of the spring. The maximum stroke of the first pulley 62 is determined by the structure of the first spring seat 61.

[0048] In this embodiment, see Figure 9 The angle limiting mechanism 5 includes a second spring seat 51 and a second pulley 52 disposed within the second spring seat 51. The second spring seat 51 and the second pulley 52 adopt the existing structure and the same installation method as the first spring seat 61 and the first pulley 62. Under the action of the second spring seat 51, the second pulley 52 always applies a vertical upward force to the lower left side of the tilting table 3. Thus, the force on one side of the tilting table 3 will cause it to rotate on the coaxial line of the two rotating shaft 41 assemblies, pushing the tilting table 3 to rotate to a certain angle. The angle of rotation depends on the amount of upward pushing stroke of the second pulley 52.

[0049] In this embodiment, see Figure 9 The first pulley 62 and the second pulley 52 are arranged in opposite directions. The upward movement of the second pulley 52 causes the tilting table 3 to rotate, which in turn causes the driving part 31 on one side of the tilting table 3 to be higher than the clamping part 32 on the other side, forming a height difference. The first pulley 62 moves downwards and abuts against the drive part 31 of the tilting table 3. Under the action of the upper mold base 1, the downward force of the first pulley 62 is greater than the force of the second pulley 52 under the second spring seat 51, thus driving the tilting table 3 to rotate. Due to the rotation of the tilting table 3, the drive part 31 of the tilting table 3 will drive the first pulley 62 to roll, and the bottom of the tilting table 3 will drive the second pulley 52 to roll. In this way, the first pulley 62 and the second pulley 52 will not interfere with each other with the tilting table 3, and the force formed by the first pulley 62 and the second pulley 52 on both sides of the tilting table 3 can effectively offset the lateral force during the rotation process, avoid the tilting table 3 from tilting due to uneven force, ensure that it rotates evenly around the axis of the rotating shaft 41, avoid rotation jamming and sudden jumping, improve the continuity and stability of the movement, and ensure that the clamping part 32 of the tilting table 3 can accurately complete the transition with the working surface of the material support part.

[0050] In this embodiment, to prevent the tilting table 3 from deflecting during rotation and affecting machining accuracy, at least one anti-deflection mechanism is also provided in the cavity 21 of the lower mold base 2. See [link to relevant documentation]. Figure 4 and Figure 9 The anti-deflection mechanism includes a slide 71 located in the middle of the bottom wall of the cavity 21 and a sliding block 72 located at the bottom of the tilting table 3. When the tilting table 3 rotates in the cavity 21, the sliding block 72 guides and slides within the slide 71. In this way, the lateral displacement of the tilting table 3 during rotation can be constrained, ensuring that the clamping mating surfaces of the clamping part 32 and the support part 22 are always aligned, avoiding the positioning deviation of the door outer panel parts caused by the tilting table 3, and ensuring the consistency of the side flange accuracy.

[0051] In this embodiment, there can be multiple anti-deflection mechanisms. See also Figure 4 The anti-deflection mechanism consists of three sets. Three equally spaced slides 71 are provided on the bottom wall of the cavity 21. Correspondingly, the bottom wall of the tilting table 3 is also provided with three sliding blocks 72 that correspond to the slides 71. This can constrain the lateral displacement of the tilting table 3 when it rotates, and ensure that the clamping surfaces of the clamping part 32 and the support part 22 can be accurately aligned.

[0052] In this embodiment, see Figure 4 and Figure 5The rotating shaft 41 assembly includes a rotating shaft 41 and a fixed platform 42 disposed on the lower mold base 2. One end of the rotating shaft 41 is engaged with a side locking hole 33 of the tilting table 3, and the other end is inserted into a through hole 42a of the fixed platform 42 to form a rotatable connection. When the tilting table 3 rotates, the rotating shaft 41 rotates synchronously within the fixed platform 42. The rotating shaft 41 includes an integrally formed long shaft portion 41a and a rectangular connecting portion 41b. The long shaft portion 41a is inserted into a wear-resistant sleeve 43 within the through hole 42a of the fixed platform 42, and the rectangular connecting portion 41b is inserted into the side locking hole 33 of the tilting table 3 for engagement and fixation. Thus, under the action of the two rotating shafts 41, the tilting table 3 is suspended within the cavity 21 of the lower mold base 2 and can also rotate within the cavity 21 via the rotating shaft 41.

[0053] In this embodiment, in order to ensure that the wedge cutter block 12 does not deviate during its downward movement and can accurately complete the side flanging and shaping, the flipping table 3 is provided with a wedge base block 34. The existing structure of the wedge base block 34 and the wedge cutter block 12 is flexibly applied to the mold of this embodiment, so that when the upper mold base 1 moves downward relative to the lower mold base 2, the wedge cutter block 12 slides on the wedge base block 34 and the clamping mating surface is misaligned, and the wedge cutter block 12 will not deviate and cause internal collision interference.

[0054] The working principle and usage process of this utility model:

[0055] During installation,

[0056] First, the upper mold base 1 is used to fix the pressing device 11 and the inclined wedge block 12 inside the upper mold base 1. There is a nitrogen spring between the pressing device 11 and the upper mold base 1, so that the pressing device 11 cooperates with the clamping part 32 of the flipping table 3 and the supporting part 22 of the lower mold base 2 under the action of the nitrogen spring, so as to apply a more uniform clamping force to the outer panel Y of the car door. Then, the first spring seat 61 and the first pulley 62 in the guiding mechanism 6 are fixed on the upper mold base 1.

[0057] Second, for the lower mold base 2, two fixed platforms 42 are bolted to the front and rear sides of the lower mold base 2. Then, the sliding platforms 71 of the three anti-deflection mechanisms are equally spaced and fixed to the bottom wall of the cavity 21 of the lower mold base 2 using fixing bolts. Next, the second spring seat 51 and the second pulley 52 of the angle limiting mechanism 5 are also fixedly installed in the bottom wall of the cavity 21. The angle limiting mechanism 5 is located to the left of the anti-deflection mechanism. Then, the tilting platform 3 is set in the cavity 21 of the lower mold base 2. The tilting platform 3 is set in the cavity 21 to ensure that the three sliding blocks 72 at its bottom position are flush with the bottom wall of the cavity 21. The three slides 71 correspond to each other and can cooperate with each other; finally, the long shaft portion 41a at one end of the rotating shaft 41 is inserted into the wear-resistant sleeve 43 of the fixed platform 42 for rotatable connection, and the rectangular connecting portion 41b at the other end is inserted into the side locking hole 33 of the tilting platform 3 for locking and fixing. In this way, the entire tilting platform 3 will be suspended in the cavity 21, and the tilting platform 3 will rotate at a certain angle and be tilted under the action of the angle limiting mechanism 5 at the lower left. The height of the driving part 31 of the tilting platform 3 is higher than the height of the clamping part 32, forming a height difference. At the same time, the clamping part 32 and the support part 22 of the lower mold base 2 will also form a misaligned height difference. See Figure 9 The mold is in its initial state when it is installed.

[0058] When doing the assignment, please refer to Figure 9 Place the outer panel Y of the car door on the support part 22 of the lower mold base 2. At this time, the left side of the car door is not pressed and is suspended in the air, and the flipping table 3 flips at a certain angle.

[0059] See Figure 10 First, the upper mold base 1 is controlled to move downward relative to the lower mold base 2. The right-side pressing device 11 of the upper mold base 1 presses the outer panel Y of the car door onto the supporting part 22 of the lower mold base 2. At the same time, the first pulley 62 on the left side of the upper mold base 1 is elastically pressed against the drive part 31 of the tilting table 3 through the first spring seat 61. Then, as the upper mold base 1 continues to move downward, the force applied by the first pulley 62 to the tilting table 3 is greater than the spring force supplied by the second spring seat 51 at the bottom of the tilting table 3 to the second pulley 52. ​​The tilting table 3 moves downward through the sliding block 72 at the bottom. The slide table 71 in the cavity 21 begins to rotate and guide until the clamping part 32 of the flipping table 3 and the supporting part 22 of the lower mold base 2 are aligned to form a continuous transition clamping mating surface, which cooperates with the presser 11 to press the outer panel Y of the car door; while the upper mold base 1 is moving downward, the wedge cutter block 12 of the upper mold base 1 will also slide on the wedge base block 34 on the flipping table 3, so that after the outer panel Y of the car door is pressed, the wedge cutter block 12 will also move in a misaligned manner relative to the clamping mating surface to flip and shape (flip the edge) the outer panel Y of the car door.

[0060] After the operation is completed, the upper mold base 1 is controlled to move upwards with a small stroke. The first pulley 62 applied to the drive unit 31 of the tilting table 3 returns to its original position under the action of the first spring seat 61. The second pulley 52 also returns to its original position under the action of the second spring seat 51, applying an upward pushing force to the lower left of the tilting table 3, causing the tilting table 3 to rotate in the opposite direction to a preset angle and remain stationary. See also Figure 9 Simultaneously, the clamping part 32 of the flipping table 3 and the supporting part 22 of the lower mold base 2 will also form a misaligned height difference, so the flipped car door outer panel Y will be suspended in the air, and the operator can easily remove the car door outer panel Y from the mold with tools. Therefore, in this utility model, the flipping table 3 is suspended in the cavity 21 of the lower mold base 2 by the rotating shaft 41 assembly. When the upper mold base 1 moves downward, it drives the flipping table 3 to rotate, so that the clamping part 32 and the supporting part 22 form a continuous pressing mating surface. The pressing mating surface, together with the misaligned movement of the inclined wedge block 12, completes the side flipping action. During the return stroke, the flipping table 3 will automatically rotate in the opposite direction under the action of the angle limiting mechanism 5 to realize the unloading. Compared with the simple linear motion of the die cavity in the prior art, the composite motion mode of linear drive and rotation angle adjustment replaces the linear advance and retreat of the die cavity slider with the rotation of the flipping table 3, reducing the guide plate.

[0061] The reduced quantity and pressure source configuration, along with the use of a rotary ejection method, eliminates the need for excessively large straight-line retraction space in the die cavity, significantly simplifying the mold structure, improving precision, reducing costs, shortening part removal time, and greatly reducing mold development costs. Therefore, this structure replaces the traditional linear ejection motion with the rotary motion of the tilting table 3, significantly simplifying the mold structure, reducing the number of pressure sources and guide plates, and improving motion precision and stability through rolling contact and anti-deflection design. This enables low-cost, high-precision Y-side flanging production of automotive door outer panels, effectively improving production efficiency.

[0062] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this utility model, but does not constitute a limitation on the scope of protection of this utility model. Modifications, equivalent substitutions, or other improvements to the embodiments of this utility model or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this utility model or the foregoing embodiments, should all be included within the scope of protection of this utility model.
