[0001] This utility model relates to the field of stamping technology, and in particular to a multi-station mold for an inner reinforcing plate of an automobile front door. Background Technology

[0002] With the development of automotive lightweight materials and intelligent manufacturing technology, in the process of hot stamping and multi-process continuous production of high-strength steel plates, it is necessary to carry out precision forming of complex-shaped car door inner reinforcement plates, which requires the use of multi-station molds. In practical use, multi-station molds with similar structures still have many defects, such as: traditional multi-station molds lack a buffer protection mechanism, conventional stamping equipment directly and rigidly contacts the workpiece, which can easily lead to uneven material deformation and premature mold wear. At the same time, the automation level of traditional multi-station molds is insufficient, which affects efficiency. Manual part removal poses safety hazards and the cycle time is unstable. Therefore, it is necessary to design a multi-station mold for the inner reinforcement plate of the front door of an automobile. Summary of the Invention

[0008] As a further improvement to the above solution, the force-bearing gear meshes with the driving gear, a top plate is slidably mounted inside the mounting bracket, and the force-bearing rack fixedly connected to the bottom of the top plate meshes with the driven gear.

[0009] The above technical solutions improve transmission efficiency and reduce the accumulation of backlash error through the dual-gear meshing design.

[0010] As a further improvement to the above solution, buffer grooves are provided on both sides of the outer surface of the mounting bracket, and a buffer plate is slidably installed inside the buffer groove.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example

[0020] Please combine Figures 1-5This embodiment of a multi-station mold for an inner reinforcing plate of a car front door includes a support assembly 1. The support assembly 1 includes a mounting bracket 101. A servo motor 104 is fixedly connected to the rear end of the mounting bracket 101. A drive rod 105 is fixedly connected to the output end of the servo motor 104 through the mounting bracket 101. An active drive gear 106 is fixedly connected to the outer surface of the drive rod 105. A bottom forming frame 107 is fixedly connected to the top of the mounting bracket 101. It also includes: The top material assembly 2 includes a top plate 205 that is slidably installed inside the mounting frame 101, and a force-bearing rack 206 related to the active drive gear 106 is fixedly connected to the bottom of the top plate 205. The buffer assembly 3 includes a buffer plate 302 that is slidably mounted inside the mounting bracket 101 via a spring damper 304, and a limit frame 303 is fixedly connected to the top of the buffer plate 302. The stamping forming assembly 4 includes a cylinder 402 fixedly connected to the top of the mounting frame 101 via a guide frame 401. The output end of the cylinder 402 is fixedly connected to a top forming frame 405 that matches the bottom forming frame 107 via a stamping seat 403.

[0021] The mounting bracket 101 has a support frame 102 fixedly connected to both sides of its outer surface. The support frame 102 has a guide frame 401 fixedly connected to its top. The mounting bracket 101 has a mounting base 103 fixedly connected to its rear end. The mounting base 103 has a drive rod 105 rotatably connected to its interior.

[0022] The inner walls of the mounting bracket 101 are fixedly connected to both sides of the connecting plate 201, and the bottom of the connecting plate 201 is fixedly connected to the connecting rod 202. The internal drive gear 204 is rotatably connected to the connecting rod 202, and the driven gear 204 passes through the connecting rod 202 and is fixedly connected to the force-bearing gear 203.

[0023] The force-bearing gear 203 meshes with the driving gear 106. A top plate 205 is slidably mounted inside the mounting bracket 101. The force-bearing rack 206 fixedly connected to the bottom of the top plate 205 meshes with the driven gear 204.

[0024] The servo motor 104 drives the drive rod 105 to rotate within the mounting base 103. Since the active drive gear 106 meshes with the force-bearing gear 203, it can ensure that the force-bearing gear 203 and the driven drive gear 204 rotate under the limit of the connecting rod 202.

[0025] The mounting bracket 101 has buffer grooves 301 on both sides of its outer surface. A buffer plate 302 is slidably installed inside the buffer groove 301. A spring damper 304 is fixedly connected to the bottom of the buffer plate 302. The bottom of the spring damper 304 is fixedly connected to the bottom of the inner wall of the buffer groove 301.

[0026] A cylinder 402 is fixedly connected to the top of the guide frame 401, and a stamping seat 403 is fixedly connected to the output end of the cylinder 402. The two sides of the stamping seat 403 are slidably installed on the inner wall of the guide frame 401 through limiting blocks 404.

[0027] A top forming frame 405 is fixedly connected to the center of the bottom of the stamping base 403. The top forming frame 405 matches the bottom forming frame 107. Buffer rods 406 are fixedly connected to the four corners of the bottom of the stamping base 403. Buffer rods 406 match the limit frame 303.

[0028] When the stamping seat 403 descends, due to the limiting effect of the guide frame 401, the buffer rod 406 can be accurately inserted into the limiting frame 303. As the stamping seat 403 continues to descend, the buffer plate 302 can be driven to contract and buffer in the buffer groove 301 under the action of the spring damper 304. The spring damper 304 can be used to ensure that the descent of the stamping seat 403 is buffered.

[0029] The implementation principle of a multi-station mold for an inner reinforcing plate of a car front door in this embodiment is as follows: the cylinder 402 drives the stamping seat 403 to descend. At this time, the limiting block 404 set on the outer surface of the stamping seat 403 can ensure that the sliding of the stamping seat 403 is limited by the horizontal limit of the guide frame 401. The steel plate to be stamped is placed between the top forming frame 405 and the bottom forming frame 107. As the stamping seat 403 descends, the stamping is completed. When the stamping seat 403 descends, due to the limitation of the guide frame 401, the buffer rod 406 can be accurately inserted into the limiting frame 303. With the continuous descent of the stamping seat 403, the buffer plate 302 can be driven to contract and buffer in the buffer groove 301 under the action of the spring damper 304. The spring damper 304 can be used to ensure that the descent of the stamping seat 403 is buffered. After stamping is completed, the cylinder 402 drives the stamping seat 403 to rise, and the servo motor 104 drives the drive rod 105 to rotate in the mounting seat 103. Since the active drive gear 106 meshes with the force-bearing gear 203, it can ensure that the force-bearing gear 203 and the driven drive gear 204 rotate under the limit of the connecting rod 202. Furthermore, since the driven drive gear 204 meshes with the force-bearing rack 206, it can drive the top plate 205 to slide in the mounting frame 101, thereby ejecting the top-formed reinforcing plate for easy handling by workers.

[0030] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
