Description

Technical Field

[0001] This application relates to the field of stamping die technology, and in particular to a stamping die for an automotive taillight mounting plate. Background Technology

[0002] A taillight mounting plate is a structural metal or plastic component that fixes and supports the taillight assembly. It is part of the body panel or frame and is usually located on the side of the body, the tailgate frame, or the rear sill area. As the connecting medium between the taillight and the body, the taillight is precisely fixed in the designated position by welding, bolts, or clips. Its main function is to ensure that the taillight maintains its installation accuracy and stability during driving vibrations. Some designs also serve to seal and waterproof, guide airflow, or integrate ventilation ducts.

[0003] Currently, the stamping process for automotive taillight mounting plates in the industry generally adopts the traditional single-operation die or ordinary progressive die production mode. That is, the material is loaded manually before stamping, and after stamping, the material needs to be unloaded in the stamping area. During the unloading process, the stamping equipment has to wait for the unloading to be completed before stamping the next automotive taillight mounting plate. When producing a large number of taillight mounting plates, the operation efficiency is low.

[0004] Therefore, this application provides a stamping die for an automotive taillight mounting plate. Summary of the Invention

[0005] The purpose of this application is to solve at least one technical problem raised in the background art.

[0006] This application provides a stamping die for an automotive taillight mounting plate, including a stamping platform, a stamping die body, and a switching mechanism; The stamping die body includes an L-shaped mounting base fixed to the back of the stamping platform. An upper die is slidably disposed on the inner wall of the L-shaped mounting base, and a lower die is disposed on the upper surface of the stamping platform. A die cavity is opened on the upper surface of the lower die. The switching mechanism includes a sliding plate slidably disposed on the upper surface of the stamping platform. There are two lower dies, which are symmetrically fixed on the upper surface of the sliding plate. The switching mechanism also includes a rectangular groove formed on the upper surface of the stamping platform and a reciprocating threaded column rotatably disposed on the inner wall of the rectangular groove. A slider is slidably disposed on the inner wall of the rectangular groove. The side of the slider is provided with a threaded hole that is threadedly connected to the outer surface of the reciprocating threaded column, and the top of the slider is fixedly connected to the lower surface of the sliding plate.

[0007] Preferably, the stamping die body further includes two symmetrical hydraulic rods embedded in the top wall of the L-shaped mounting base, and the telescopic ends of the hydraulic rods are fixedly connected to the upper surface of the upper die.

[0008] By adopting the above technical solution, the upper and lower dies can be closed by extending the hydraulic rod, thereby completing the stamping process.

[0009] Preferably, the surface of the L-shaped mounting base is provided with a strip-shaped opening, and the upper surface of the stamping platform is provided with a connecting groove corresponding to the strip-shaped opening and communicating with the rectangular groove. A first rotating shaft is rotatably provided on one inner wall of the strip-shaped opening. A gear plate is fixed on the surface of the first rotating shaft. An L-shaped rod is fixed on the back of the upper die, and a straight rack that meshes with the gear plate is provided on the surface of the L-shaped rod.

[0010] By adopting the above technical solution, the L-shaped rod can be driven to move up and down during the up and down movement of the upper mold, thereby driving the gear plate to rotate automatically under the action of the rack.

[0011] Preferably, a second rotating shaft is rotatably provided on the inner wall of the other side of the strip-shaped opening, and a one-way ratchet mechanism is provided at the ends of the first rotating shaft and the second rotating shaft. The end of the first rotating shaft is fixedly connected to the input end of the one-way ratchet mechanism, and the end of the second rotating shaft is fixedly connected to the output end of the one-way ratchet mechanism.

[0012] By adopting the above technical solution, under the action of the one-way ratchet mechanism, when the L-shaped bar moves downward and drives the gear plate and the first rotating shaft to rotate, the rotation of the first rotating shaft cannot drive the second rotating shaft to rotate. On the contrary, when the L-shaped bar moves upward, it can drive the gear plate and the first rotating shaft to reverse, thereby driving the second rotating shaft to follow the first rotating shaft to reverse.

[0013] Preferably, a baffle is fixedly provided on the inner wall of the rectangular groove, and a rotating hole is provided on the surface of the baffle to rotately connect with the outer surface of the reciprocating threaded column. Both the second rotating shaft and the reciprocating threaded column are fixedly provided with transmission wheels, and transmission belts are sleeved on the surfaces of the two transmission wheels.

[0014] By adopting the above technical solution, during the rotation of the second rotating shaft, the reciprocating threaded column can be driven to rotate automatically under the action of the two transmission wheels and the transmission belt.

[0015] Preferably, the upper surface of the stamping platform is fixed with two symmetrical horizontal slide rails, and the sliding plate is slidably connected to the upper surface of the stamping platform through the two horizontal slide rails.

[0016] By adopting the above technical solution, the sliding plate can be made to slide horizontally stably and smoothly under the action of two horizontal slide rails.

[0017] Preferably, the surface of the stamping platform and the interior of the lower die are provided with an ejector mechanism. The ejector mechanism includes a sealing cavity opened inside the lower die and a sealing disc slidably disposed on the inner wall of the sealing cavity. Two symmetrical ejector rods are fixed on the upper surface of the sealing disc.

[0018] By adopting the above technical solution, the top rod can be moved up and down by the up and down movement of the sealing disc.

[0019] Preferably, the inner bottom wall of the mold cavity is provided with an annular sealing groove, and a top ring is slidably provided on the inner wall of the annular sealing groove. A sealing sliding hole extending into the sealing cavity is provided on the inner bottom wall of the annular sealing groove. The top end of the push rod extends into the interior of the annular sealing groove and is fixedly connected to the lower surface of the top ring. The outer surface of the push rod is slidably connected to the inner wall of the sealing sliding hole. Four vertical return springs are fixedly arranged in a circumferential array on the lower surface of the sealing disc, and the bottom ends of the four vertical return springs are all fixedly connected to the inner bottom wall of the sealing cavity.

[0020] By adopting the above technical solution, the top ring can be moved up or down by the push rod during the up-and-down movement of the sealing disc, so as to achieve the purpose of automatic material ejection. Moreover, the setting of the vertical reset spring facilitates the rapid reset of the sealing disc.

[0021] Preferably, the ejector mechanism further includes two fixed plates symmetrically fixed on the surface of the stamping platform, and each of the two fixed plates is fixed with a telescopic inflatable airbag. The telescopic ends of the two telescopic inflatable airbags correspond to the two lower dies respectively, and the inner wall of the telescopic inflatable airbag is provided with a transverse return spring.

[0022] By adopting the above technical solution, the lower mold can squeeze the telescopic inflatable airbag during the movement of the sliding plate, and the telescopic inflatable airbag can be quickly reset under the action of the lateral return spring.

[0023] Preferably, the end of the telescopic inflatable airbag is provided with a connecting hose, one end of which extends into the interior of the telescopic inflatable airbag and the other end of which extends into the interior of the sealed cavity.

[0024] By adopting the above technical solution, when the telescopic inflatable airbag is squeezed, the air inside the telescopic inflatable airbag can be transported to the sealed cavity through the connecting hose. At the same time, when the telescopic inflatable airbag is reset, the air inside the sealed cavity can be re-inhaled into the telescopic inflatable airbag through the connecting hose.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. The stamping die for an automotive taillight mounting plate described in this application, by setting a stamping die body and a switching mechanism, allows the material plate to be placed in the die cavity of the lower die during the stamping process of the automotive taillight mounting plate. Then, the hydraulic rod is activated to drive the upper die downwards, achieving stamping. During the downward movement of the upper die, an L-shaped rod is driven downwards, which in turn drives a rack and pinion to rotate. The rotation of the pinion drives a first rotating shaft to rotate. The rotation of the first rotating shaft, under the action of a one-way ratchet mechanism, cannot drive a second rotating shaft to rotate. When the upper and lower dies are closed, the L-shaped rod moves to its maximum position, at which point the rack and pinion disengage. After stamping one lower die, the hydraulic rod is activated to retract, driving the upper die upwards and resetting. The device can drive the L-shaped rod to move upwards. During the upward movement of the L-shaped rod, in the first third of the movement trajectory, the rack does not mesh with the gear plate, so it cannot drive the gear plate to rotate. When it continues to move upwards, in the latter two-thirds of the movement trajectory, the rack can mesh with the gear plate, thereby driving the gear plate and the first rotating shaft to reverse. The reversal of the first rotating shaft drives the second rotating shaft to rotate under the action of the one-way ratchet mechanism. The rotation of the second rotating shaft drives the reciprocating threaded column to rotate under the action of the two transmission wheels and the transmission belt. The rotation of the reciprocating threaded column drives the slider to move. The movement of the slider drives the sliding plate to move a specified distance, thereby realizing the purpose of automatically switching between the stamped lower die and the unstamped lower die. This facilitates the continuous stamping process of batches of automotive taillight mounting plates and effectively improves work efficiency.

[0026] 2. The stamping die for an automotive taillight mounting plate described in this application, by setting an ejector mechanism, enables automatic switching between the two lower dies during the movement of the sliding plate. When the sliding plate moves to the left and continues to move after reaching a designated position, the lower die that has been stamped on the left can compress the telescopic inflatable airbag on the left, allowing the air inside the telescopic inflatable airbag to enter the sealing cavity through the connecting hose, increasing the pressure inside the sealing cavity. This, in turn, drives the sealing disc to move upward. The upward movement of the sealing disc drives the two ejector rods to move upward, thereby enabling the two ejector rods to push the top ring upward from the inner bottom wall of the die cavity. The top ring can automatically push the stamped automotive taillight mounting plate out of the die cavity. Thus, during the automatic switching between the two lower dies, the purpose of automatically ejecting the stamped automotive taillight mounting plate from the inner die cavity of the lower die is achieved, making it easier for personnel to quickly pick up the plate and further improving work efficiency.

Detailed Implementation

[0029] The following is in conjunction with the appendix Figure 1 To be continued Figure 8 This application will be described in further detail below.

[0030] Example 1 Please refer to the following carefully. Figures 1 to 6A stamping die for an automotive taillight mounting plate includes a stamping platform 100, a stamping die body 200, and a switching mechanism 300. The stamping die body 200 includes an L-shaped mounting base 201 fixed to the back of the stamping platform 100. An upper die 202 is slidably disposed on the inner wall of the L-shaped mounting base 201, and a lower die 203 is disposed on the upper surface of the stamping platform 100. A die cavity 204 is formed on the upper surface of the lower die 203. The switching mechanism 300 includes a sliding mechanism slidably disposed on the upper surface of the stamping platform 100. The sliding plate 301 has two lower dies 203, which are symmetrically fixed on the upper surface of the sliding plate 301. The switching mechanism 300 also includes a rectangular groove on the upper surface of the stamping platform 100, and a reciprocating threaded column 302 rotatably disposed on the inner wall of the rectangular groove. A slider 303 is slidably disposed on the inner wall of the rectangular groove. The side of the slider 303 is provided with a threaded hole that is threadedly connected to the outer surface of the reciprocating threaded column 302. The top of the slider 303 is fixedly connected to the lower surface of the sliding plate 301.

[0031] Please refer to this carefully. Figure 1 , Figure 2 The stamping die body 200 also includes two symmetrical hydraulic rods 205 embedded in the top wall of the L-shaped mounting base 201, and the telescopic ends of the hydraulic rods 205 are fixedly connected to the upper surface of the upper die 202.

[0032] Specifically, the extension of the hydraulic rod 205 enables the upper die 202 and the lower die 203 to close, thereby completing the stamping process.

[0033] Please refer to this carefully. Figure 4 , Figure 6 The surface of the L-shaped mounting base 201 has a strip-shaped opening, and the upper surface of the stamping platform 100 has a connecting groove corresponding to the strip-shaped opening and communicating with the rectangular groove. A first rotating shaft 304 is rotatably provided on one side inner wall of the strip-shaped opening. A gear plate 305 is fixedly provided on the surface of the first rotating shaft 304. An L-shaped rod 306 is fixedly provided on the back of the upper die 202, and a straight rack 307 that meshes with the gear plate 305 is provided on the surface of the L-shaped rod 306.

[0034] Specifically, during the up-and-down movement of the upper mold 202, the L-shaped rod 306 can be driven to move up and down, thereby driving the gear plate 305 to rotate automatically under the action of the rack 307.

[0035] Please refer to this carefully. Figure 4 , Figure 6 A second rotating shaft 308 is rotatably provided on the inner wall of the other side of the strip-shaped opening. A one-way ratchet mechanism 309 is provided at the ends of the first rotating shaft 304 and the second rotating shaft 308. The end of the first rotating shaft 304 is fixedly connected to the input end of the one-way ratchet mechanism 309, and the end of the second rotating shaft 308 is fixedly connected to the output end of the one-way ratchet mechanism 309.

[0036] Specifically, under the action of the one-way ratchet mechanism 309, the L-shaped rod 306 moves downward and drives the gear plate 305 and the first rotating shaft 304 to rotate. During this process, the rotation of the first rotating shaft 304 cannot drive the second rotating shaft 308 to rotate. On the contrary, when the L-shaped rod 306 moves upward, it can drive the gear plate 305 and the first rotating shaft 304 to reverse, thereby driving the second rotating shaft 308 to follow the first rotating shaft 304 to reverse.

[0037] Please refer to this carefully. Figure 4 , Figure 6 A baffle is fixedly provided on the inner wall of the rectangular groove, and a rotating hole is provided on the surface of the baffle to be rotatably connected to the outer surface of the reciprocating threaded column 302. A transmission wheel 3010 is fixedly provided on the surface of both the second rotating shaft 308 and the reciprocating threaded column 302, and a transmission belt 3011 is sleeved on the surface of the two transmission wheels 3010.

[0038] Specifically, during the rotation of the second rotating shaft 308, the reciprocating threaded column 302 can be automatically rotated by the action of the two transmission wheels 3010 and the transmission belt 3011.

[0039] Please refer to this carefully. Figure 1 , Figure 2 Two symmetrical horizontal slide rails 3012 are fixed on the upper surface of the stamping platform 100, and the sliding plate 301 is slidably connected to the upper surface of the stamping platform 100 through the two horizontal slide rails 3012.

[0040] Specifically, the sliding plate 301 can slide smoothly and stably in the lateral direction under the action of the two horizontal slide rails 3012.

[0041] In this embodiment, by setting the stamping die body 200 and the switching mechanism 300, when stamping the car taillight mounting plate, the material plate can be placed in the die cavity 204 on the lower die 203. Then, the hydraulic rod 205 is activated to drive the upper die 202 to move downward, realizing stamping. During the downward movement of the upper die 202, the L-shaped rod 306 can be driven to move downward. The downward movement of the L-shaped rod 306 drives the straight rack 307 to move downward and drives the gear plate 305 to advance. As the gear 305 rotates, it drives the first rotating shaft 304 to rotate. The rotation of the first rotating shaft 304, under the action of the one-way ratchet mechanism 309, cannot drive the second rotating shaft 308 to rotate. When the upper die 202 and lower die 203 are closed, the L-shaped rod 306 moves down to its maximum position. At this time, the straight rack 307 disengages from the gear 305. After stamping one lower die 203, the hydraulic rod 205 retracts, causing the upper die 202 to move upward and reset. At this time, the L-shaped rod can be driven. As L-shaped rod 306 moves upward, in the first third of its trajectory, rack 307 does not mesh with gear disc 305, thus failing to rotate gear disc 305. However, as it continues upward, in the latter two-thirds of its trajectory, rack 307 meshes with gear disc 305, causing gear disc 305 and first rotating shaft 304 to reverse. The reversal of first rotating shaft 304, under the action of one-way ratchet mechanism 309, drives second rotating shaft 308 to rotate. The rotation of second rotating shaft 308, under the action of two transmission wheels 3010 and transmission belt 3011, drives reciprocating threaded column 302 to rotate. The rotation of reciprocating threaded column 302 drives slider 303 to move. The movement of slider 303 drives sliding plate 301 to move a specified distance, thereby achieving automatic switching between stamped and unstamped lower die 203. This facilitates continuous stamping of batches of automotive taillight mounting plates, effectively improving work efficiency.

[0042] Example 2 Based on Example 1, referring to Figure 7 and Figure 8 And unlike Example 1, the following is true: Please refer to this carefully. Figure 7 , Figure 8 The surface of the stamping platform 100 and the interior of the lower die 203 are provided with an ejector mechanism 400. The ejector mechanism 400 includes a sealing cavity 401 opened inside the lower die 203 and a sealing disc 402 slidably disposed on the inner wall of the sealing cavity 401. Two symmetrical ejector rods 403 are fixed on the upper surface of the sealing disc 402.

[0043] Specifically, the up-and-down movement of the sealing disc 402 can drive the top rod 403 to move up and down.

[0044] Please refer to this carefully. Figure 7 , Figure 8The inner bottom wall of the mold cavity 204 is provided with an annular sealing groove, and a top ring 404 is slidably provided on the inner wall of the annular sealing groove. A sealing sliding hole extending into the sealing cavity 401 is provided on the inner bottom wall of the annular sealing groove. The top end of the push rod 403 extends into the interior of the annular sealing groove and is fixedly connected to the lower surface of the top ring 404. The outer surface of the push rod 403 is slidably connected to the inner wall of the sealing sliding hole. Four vertical return springs 405 are fixedly arranged in a circumferential array on the lower surface of the sealing disc 402, and the bottom ends of the four vertical return springs 405 are fixedly connected to the inner bottom wall of the sealing cavity 401.

[0045] Specifically, during the up-and-down movement of the sealing disc 402, the top rod 403 drives the top ring 404 to move up or down, thereby achieving the purpose of automatic material ejection. Moreover, the vertical reset spring 405 facilitates the rapid reset of the sealing disc 402.

[0046] Please refer to this carefully. Figure 7 , Figure 8 The ejector mechanism 400 also includes two fixed plates 406 symmetrically fixed on the upper surface of the stamping platform 100, and telescopic inflatable airbags 407 are fixed on the surface of both fixed plates 406. The telescopic ends of the two telescopic inflatable airbags 407 correspond to the two lower dies 203 respectively, and the inner wall of the telescopic inflatable airbags 407 is provided with a transverse return spring 408.

[0047] Specifically, during the movement of the sliding plate 301, the lower mold 203 can compress the telescopic inflatable airbag 407, and under the action of the transverse return spring 408, the telescopic inflatable airbag 407 can be quickly reset.

[0048] Please refer to this carefully. Figure 7 , Figure 8 The end of the telescopic inflatable airbag 407 is provided with a connecting hose 409. One end of the connecting hose 409 extends into the interior of the telescopic inflatable airbag 407, and the other end of the connecting hose 409 extends into the interior of the sealing cavity 401.

[0049] Specifically, when the telescopic inflatable airbag 407 is compressed, air inside the telescopic inflatable airbag 407 can be transported to the sealed cavity 401 through the connecting hose 409. At the same time, when the telescopic inflatable airbag 407 is reset, air inside the sealed cavity 401 can be re-inhaled into the telescopic inflatable airbag 407 through the connecting hose 409.

[0050] In this embodiment, by setting the ejector mechanism 400, the two lower dies 203 are automatically switched during the movement of the sliding plate 301. When the sliding plate 301 moves to the left and continues to move after reaching the designated position, the lower die 203 on the left, which has completed stamping, can compress the telescopic inflatable airbag 407 on the left. This allows the air inside the telescopic inflatable airbag 407 to enter the sealing cavity 401 through the connecting hose 409, increasing the pressure inside the sealing cavity 401. This, in turn, drives the sealing disc 402 to move upward, sealing the cavity. The upward movement of the sealing plate 402 can drive the two ejector rods 403 to move upward, thereby enabling the two ejector rods 403 to push the top ring 404 upward from the inner bottom wall of the mold cavity 204. This allows the top ring 404 to automatically push the stamped car taillight mounting plate inside the mold cavity 204 upward. In the process of automatic switching between the two lower dies 203, the stamped car taillight mounting plate inside the mold cavity 204 of the lower die 203 can be automatically ejected, making it easier for personnel to quickly pick it up and further improving work efficiency.

[0051] Working principle: When stamping the automotive taillight mounting plate, the material plate is placed in the mold cavity 204 on the lower mold 203. Then, the hydraulic rod 205 is activated to drive the upper mold 202 to move downward, achieving stamping. During the downward movement of the upper mold 202, the L-shaped rod 306 is driven to move downward. The downward movement of the L-shaped rod 306 drives the rack 307 to move downward and drives the gear 305 to rotate. The rotation of the gear 305 drives the first rotating shaft 304 to rotate. The rotation of the first rotating shaft 304 cannot drive the second rotating shaft 308 to rotate under the action of the one-way ratchet mechanism 309. When the upper mold 202 and the lower mold 203 are closed, the L-shaped rod 306 moves down to its maximum position. At this time, the rack 307 and the gear 305... 05 Disengagement: After the lower die 203 is stamped, the hydraulic rod 205 retracts, causing the upper die 202 to move upward and reset. At this time, the L-shaped rod 306 moves upward. During the upward movement of the L-shaped rod 306, in the first third of its trajectory, the rack 307 does not mesh with the gear disc 305, therefore it cannot rotate the gear disc 305. As it continues to move upward, in the latter two-thirds of its trajectory, the rack 307 meshes with the gear disc 305, thus causing the gear disc 305 and the first rotating shaft 304 to reverse. The reversal of the first rotating shaft 304, under the action of the one-way ratchet mechanism 309, drives the second rotating shaft 308 to rotate. The rotation of the second rotating shaft 308 is controlled by the two transmission wheels 3010 and... The transmission belt 3011 drives the reciprocating threaded column 302 to rotate. The rotation of the reciprocating threaded column 302 drives the slider 303 to move. The movement of the slider 303 drives the sliding plate 301 to move a specified distance, thereby achieving the purpose of automatically switching between the stamped lower die 203 and the unstamped lower die 203. This facilitates continuous stamping of batches of automotive taillight mounting plates, effectively improving work efficiency. Moreover, during the movement of the sliding plate 301, when the two lower dies 203 are automatically switched, as the sliding plate 301 moves to the left and continues to move after reaching the specified position, the stamped lower die 203 on the left can compress the telescopic inflatable airbag 407 on the left, causing the telescopic inflatable airbag to expand. Air inside the bladder 407 can enter the sealing cavity 401 through the connecting hose 409, increasing the pressure inside the sealing cavity 401. This increases the pressure, causing the sealing disc 402 to move upward. The upward movement of the sealing disc 402 then causes the two ejector rods 403 to move upward, pushing the top ring 404 upward from the inner bottom wall of the mold cavity 204. This allows the top ring 404 to automatically push the stamped car taillight mounting plate out of the mold cavity 204. Thus, during the automatic switching of the two lower dies 203, the stamped car taillight mounting plate inside the mold cavity 204 of the lower die 203 can be automatically ejected, making it easier for personnel to quickly retrieve and further improving work efficiency.
