Technical Field
[0001] This utility model belongs to the field of mold stamping technology, and in particular relates to a stamping mold for a precision motor. Background Technology
[0002] With the rapid development of new energy vehicles, industrial automation and aerospace, precision motors, as the core components of energy conversion and control, have seen explosive growth in market demand. In the large-scale production of precision motors, stamping dies are the core equipment for manufacturing key components such as motor cores and terminals, and their performance directly determines the precision, energy efficiency and reliability of the motor.
[0003] However, the existing stamping dies for precision motors are prone to damage due to the large stamping force during use, which reduces the stamping speed and consequently lowers the production efficiency of the stamping dies for precision motors. Utility Model Content
[0004] The purpose of this utility model is to provide a stamping die for a precision motor. By setting a buffer mechanism, it solves the problem that the existing stamping dies for precision motors are prone to damage due to excessive stamping force during use, which reduces the stamping speed and thus reduces the production efficiency of the stamping dies for precision motors.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model is a stamping die for a precision motor, including a base, on which a pressing mechanism and two buffer mechanisms are provided;
[0007] The pressing mechanism includes several sliding rods fixedly connected to the top of the base. A fixed plate is fixedly connected to the top of the sliding rods. A hinge block is fixedly connected to the bottom of the fixed plate. A rectangular plate is slidably connected to the outer wall of the sliding rods. The buffer mechanism includes two fixed blocks fixedly connected to the bottom of the rectangular plate. A small hinge rod is hinged to each of the two fixed blocks. A buffer plate is provided at the bottom of the rectangular plate. Two fixed blocks are fixedly connected to the top of the buffer plate. A small hinge rod is hinged to each of the two fixed blocks.
[0008] Furthermore, a lower mold is fixedly connected to the top of the base, a support leg is fixedly connected to the bottom of the base, a trapezoidal groove is provided at the bottom of the fixed plate, a slider is slidably connected to the inner wall of the trapezoidal groove, and a large hinge rod is hinged on both the hinge block and the slider, and the two large hinge rods are hinged together.
[0009] Furthermore, a hydraulic cylinder is fixedly connected to the top of the fixed plate, and the right side of the hydraulic cylinder is fixedly connected to the slider. A hinge block is fixedly connected to the top of the rectangular plate, and a trapezoidal groove is provided on the top of the rectangular plate.
[0010] Furthermore, the inner wall of the trapezoidal groove is slidably connected to a slider, and the slider and the hinge block are respectively hinged to two large hinge rods. The bottom of the rectangular plate is fixedly connected to an upper mold.
[0011] Furthermore, each of the two small hinge rods is hinged to one of the two small hinge rods and is provided with a bidirectional hinge block. A telescopic rod is fixedly connected between the two bidirectional hinge blocks. A spring is sleeved on the outer wall of the telescopic rod. The front and rear sides of the spring are fixedly connected to the two bidirectional hinge blocks respectively.
[0012] This utility model has the following beneficial effects:
[0013] 1. By setting up a pressing mechanism and activating the hydraulic cylinder, the hydraulic cylinder will retract, causing the slider one to slide within the trapezoidal slide groove one and move closer to the hinge block one. The slider one will then move the corresponding large hinge rod. At this time, the two large hinge rods rotate around the hinge point, thus reducing the angle between the two large hinge rods. The corresponding large hinge rod of the hinge block one pulls the slider two to slide within the trapezoidal slide groove two and move closer to the hinge block two, thereby pushing the rectangular plate to slide on several slide rods. With the parallel design of several slide rods, the rectangular plate is ensured to move smoothly. When the rectangular plate moves downward, it drives the upper mold to move downward, thereby pressing down the material in the lower mold. After the material is stamped, the hydraulic cylinder pushes the slider one to slide within the trapezoidal slide groove one and move away from the hinge block one. Through the opposite movement process, the upper mold is moved away from the lower mold, so that it can remain horizontal during the up and down movement, avoiding tilting or swaying. This ensures the stability of the upper mold during the pressing and rising process, which is beneficial to improving stamping accuracy, production efficiency, and product qualification rate.
[0014] 2. By setting up a buffer mechanism, when the rectangular plate drives the upper mold to press, the rectangular plate drives the buffer plate to move downward and contact the top of the base. At this time, the impact force of the downward pressure will act on the buffer plate. Under the action of the downward pressure, the buffer plate moves upward. At this time, the buffer plate squeezes the two small hinge rods through the two fixed blocks 2 respectively. In turn, the two small hinge rods 2 squeeze the two small hinge rods 1 through the two bidirectional hinge blocks on the two small hinge rods 2. At this time, the two small hinge rods 1 rotate around the two fixed blocks 1 respectively. As a result, the angle between the two small hinge rods 2 and the two small hinge rods 1 is reduced, thereby pushing the two bidirectional hinge blocks closer to each other, thus squeezing the telescopic rod and the spring. At this time, the spring deforms and generates elastic force. When the spring rises, under the action of the spring force, the buffer plate is reset, thus protecting the core components of the mold, such as the upper mold and the lower mold, from impact damage, extending the mold life, avoiding mold damage or uneven material deformation caused by rigid collisions, and improving mold reliability and processing quality.

[0025] Please see Figure 1-5 As shown, this utility model is a stamping die for a precision motor, including a base 1. A pressing mechanism 2 and two buffer mechanisms 3 are provided on the base 1. The pressing mechanism 2 includes several sliding rods 211 fixedly connected to the top of the base 1. A fixing plate 212 is fixedly connected to the top of the sliding rods 211. A hinge block 213 is fixedly connected to the bottom of the fixing plate 212. A rectangular plate 218 is slidably connected to the outer wall of the sliding rods 211. A lower die 111 is fixedly connected to the top of the base 1. A support leg 112 is fixedly connected to the bottom of the base 1. A trapezoidal groove 214 is formed at the bottom of the fixing plate 212. A slider 215 is slidably connected to the inner wall of the trapezoidal groove 214. Large hinge rods 216 are hinged to both the hinge block 213 and the slider 215. The 16-phase hinge configuration includes a hydraulic cylinder 217 fixedly connected to the top of the fixed plate 212, with the right side of the hydraulic cylinder 217 fixedly connected to the slider 215. A hinge block 219 is fixedly connected to the top of the rectangular plate 218, and a trapezoidal groove 2110 is provided on the top of the rectangular plate 218. A slider 2111 is slidably connected to the inner wall of the trapezoidal groove 2110. The slider 2111 and the hinge block 219 are respectively hinged to two large hinge rods 216. An upper mold 2112 is fixedly connected to the bottom of the rectangular plate 218. By setting a pressing mechanism 2, the upper mold 2112 can remain horizontal during the up and down movement, avoiding tilting or shaking. This ensures the stability of the upper mold 2112 during the pressing and rising process, which is beneficial to improving stamping accuracy, production efficiency, and product qualification rate.
[0026] The buffer mechanism 3 includes two fixed blocks 311 fixedly connected to the bottom of the rectangular plate 218. Each of the two fixed blocks 311 is hinged with a small hinge rod 312. A buffer plate 313 is provided at the bottom of the rectangular plate 218. Two fixed blocks 314 are fixedly connected to the top of the buffer plate 313. Each of the two fixed blocks 314 is hinged with a small hinge rod 315. A bidirectional hinge block 316 is hinged between each of the two small hinge rods 312 and the two small hinge rods 315. A telescopic rod 317 is fixedly connected between the two bidirectional hinge blocks 316. A spring 318 is sleeved on the outer wall of the telescopic rod 317. The front and rear sides of the spring 318 are fixedly connected to the two bidirectional hinge blocks 316. By setting up the buffer mechanism 3, the core components of the mold, such as the upper mold and the lower mold, are protected from impact damage, the mold life is extended, mold damage or uneven material deformation caused by rigid collisions is avoided, and the mold reliability and processing quality are improved.
[0027] A specific application of this embodiment is as follows: During use, the material is placed in the lower mold 111, and then the hydraulic cylinder 217 is activated. At this time, the hydraulic cylinder 217 will retract, thereby driving the slider 215 to slide in the trapezoidal slide groove 214 and move closer to the hinge block 213. The slider 215 will drive the corresponding large hinge rod 216 to move. At this time, the two large hinge rods 216 rotate around the hinge point, thereby reducing the angle between the two large hinge rods 216. At this time, the large hinge rod 216 corresponding to the hinge block 213 pulls the slider 215. Block 2111 slides within trapezoidal slide groove 2110 and approaches hinge block 219, thereby pushing rectangular plate 218 to slide on several slide rods 211. The parallel design of the slide rods 211 ensures smooth movement of rectangular plate 218. As rectangular plate 218 moves downwards, it drives upper mold 2112 downwards, thus pressing down the material in lower mold 111. After the material stamping is complete, hydraulic cylinder 217 pushes slider 215 to slide within trapezoidal slide groove 214 and away from hinge block 213. Through the opposite motion process described above, the upper mold 2112 is moved away from the lower mold 111. When the rectangular plate 218 drives the upper mold 2112 to press, the rectangular plate 218 drives the buffer plate 313 to move downward and contact the top of the base 1. At this time, the downward impact force will act on the buffer plate 313. Under the action of the downward pressure, the buffer plate 313 moves upward. At this time, the buffer plate 313 squeezes the two small hinge rods 315 through the two fixed blocks 314 respectively, thereby passing through the two small hinge rods 315 respectively. Two bidirectional hinge blocks 316 press against two small hinge rods 312. At this time, the two small hinge rods 312 rotate around the two fixed blocks 311, respectively. As a result, the angle between the two small hinge rods 315 and the two small hinge rods 312 decreases, thereby pushing the two bidirectional hinge blocks 316 closer to each other. This compresses the telescopic rod 317 and the spring 318. At this time, the spring 318 deforms and generates elastic force. When the spring 318 rises, the buffer plate 313 is reset under the action of the elastic force of the spring 318.
