Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, specifically a stamping die for producing stamped parts for new energy vehicles. Background Technology

[0002] New energy vehicles refer to vehicles that use electricity or other clean energy as power. In the production process, new energy vehicles also need to be produced and processed by stamping dies. Stamping is mainly divided into two steps: punching out the shape of the workpiece and punching off the excess scrap. Of course, some stamping parts do not need to be punched off the excess scrap during production, or the punching work is completed at the same time as the blank is stamped.

[0003] An existing patent (publication number: CN222519610U) discloses a stamping die for an automotive bracket, including a housing with a hydraulic lifting device fixedly installed at the upper end of the housing; it also includes: two lower dies disposed in cavities at the lower end of the housing, and the lower dies are rotatably connected to the housing via a rotating shaft, the inner cavities of the two lower dies forming the forming cavity of the bracket when they are closed; an upper die disposed above the two lower dies, with a lifting block fixedly installed at the upper end of the upper die; and a transmission box disposed at the rear end of the housing, with a rack plate installed inside the transmission box, and transmission gears rotatably installed on both sides of the lower end of the transmission box, a screw fixedly installed at the front end of the transmission gear, and a push rod installed outside the screw. This invention solves the problem that stamping dies cannot improve production continuity while ensuring stamping stability based on the outer contour of the oil pipe.

[0004] Although the aforementioned patent improves production continuity by setting up a hydraulic lifting device to ensure stamping stability during the stamping process, manual loading and unloading is still required after the finished product is ejected. Furthermore, after stamping, the workpiece tends to conform to the curved surface of the mold, and manual loading and unloading takes time, resulting in low overall efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a stamping die for the production of stamped parts for new energy vehicles, which has the advantages of rapid demolding of finished products and high production efficiency, thus solving the problems mentioned in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stamping die for the production of stamping parts for new energy vehicles, including a base, a turntable rotatably connected to the upper surface of the base, three sets of die assemblies arranged on the upper surface of the turntable, an auxiliary demolding device arranged inside the die assembly, and a pressing assembly fixed to the side of the base;

[0007] The mold assembly includes a lifting plate and an upper mold disposed on the bottom surface of the lifting plate. A support plate fixed to the upper surface of the turntable is disposed below the upper mold, and a lower mold corresponding to the upper mold is fixed on the upper surface of the support plate.

[0008] The lower mold has a slot in its inner bottom wall, which passes through the lower mold, the support plate, and the turntable. A cavity is slidably connected to the inner wall of the slot. The auxiliary demolding device includes a compression cylinder installed inside the cavity. A pressure block is installed at the top of the compression cylinder, which passes through the cavity. A one-way valve is installed at the bottom of the compression cylinder. A drain pipe is installed on the side of the compression cylinder, and the other end of the drain pipe passes through the cavity.

[0009] Furthermore, multiple sets of uprights are fixed to the upper surface of the turntable, the uprights pass through the corresponding lifting plates, and the ends of the uprights are equipped with stops.

[0010] The above solution uses uprights to maintain the stability of the lifting platform during the lifting process, preventing the platform from shifting during lifting.

[0011] Furthermore, a first return spring is sleeved on the outer surface of the upright, one end of the first return spring is fixed to the turntable, and the other end of the first return spring is fixed to the lifting plate.

[0012] The above scheme allows the lifting plate to be reset by the elastic force of the first reset spring, thereby achieving the separation of the upper mold and the lower mold.

[0013] Furthermore, a second return spring is provided inside the compression cylinder. One end of the second return spring is fixed to the pressure block, and the other end of the second return spring is fixed to the inner bottom wall of the compression cylinder.

[0014] The above method allows the pressure block to be reset by the elastic force of the second reset spring.

[0015] Furthermore, multiple sets of brackets are fixed to the bottom surface of the turntable, each set of brackets corresponding to the slot. A reset telescopic rod and a third reset spring are installed on the upper surface of the brackets, and the other end of the reset telescopic rod and the third reset spring are fixed to the cavity.

[0016] The above method allows the cavity to be reset by the elastic force of the third reset spring.

[0017] Furthermore, the pressing assembly includes a vertical plate fixed to the side of the base, a fixing plate fixed to the side of the vertical plate, a hydraulic cylinder mounted on the upper surface of the fixing plate, and a pressure plate mounted on the output end of the hydraulic cylinder.

[0018] The above scheme allows the hydraulic cylinder's output end to move the pressure plate, which then contacts and presses down on the upper mold, causing the upper mold to descend.

[0019] Furthermore, a motor is mounted on the upper surface of the base, and the output end of the motor is connected to the turntable.

[0020] The above method allows the turntable to rotate via a motor.

[0021] Furthermore, a one-way feed valve for replenishing material is installed on the bottom surface of the cavity, and the interior of the cavity is filled with a release agent.

[0022] The above method allows for the replenishment of release agent into the cavity via a one-way feed valve.

[0023] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0024] This new type of stamping die for producing stamped parts for new energy vehicles features three sets of die components. When one set of die components is performing a stamping operation, another set of die components, driven by a turntable, transfers the finished product. During the stamping process, the compression cylinder discharges release agent through the drain pipe, preventing the finished product from adhering to the surface of the lower die and facilitating demolding. Operators only need to stand on the side away from the lower pressing component and wait for the turntable to transfer the stamped die component to them. After taking the finished product, they can place new raw material to complete the loading and unloading process. During the loading and unloading process, the lower pressing component can continue to press new raw material without stopping the machine, allowing the entire process of loading, stamping, and unloading to be completed simultaneously. Combined with rapid demolding, this improves the overall work efficiency. Attached Figure Description

[0038] Please see Figure 2 , Figure 4 and Figure 5 The lower mold 304 has a slot on its inner bottom wall, which passes through the lower mold 304, the support plate 303 and the turntable 2. The inner wall of the slot is slidably connected to a cavity 401. The auxiliary demolding device 4 includes a compression cylinder 402 installed inside the cavity 401. A pressure block 403 is installed at the top of the compression cylinder 402, which passes through the cavity 401. A one-way valve 404 is installed at the bottom of the compression cylinder 402. A drain pipe 405 is installed on the side of the compression cylinder 402, and the other end of the drain pipe 405 passes through the cavity 401.

[0039] Multiple sets of uprights 6 are fixed on the upper surface of the turntable 2. The uprights 6 pass through the corresponding lifting plates 301. The ends of the uprights 6 are equipped with stops 7. The uprights 6 can maintain the stability of the lifting plates 301 during the lifting process and prevent the lifting plates 301 from deviating during the lifting process. The outer surface of the uprights 6 is fitted with a first return spring 8. One end of the first return spring 8 is fixed to the turntable 2 and the other end of the first return spring 8 is fixed to the lifting plates 301. The elastic force of the first return spring 8 can push the lifting plates 301 to return to their original position, thereby realizing the separation of the upper mold 302 and the lower mold 304.

[0040] The compression cylinder 402 is equipped with a second return spring 406. One end of the second return spring 406 is fixed to the pressure block 403, and the other end of the second return spring 406 is fixed to the inner bottom wall of the compression cylinder 402.

Each set of brackets 9 corresponds to the slot. The upper surface of the brackets 9 is equipped with a reset telescopic rod 10 and a third return spring 11. The other end of the reset telescopic rod 10 and the third return spring 11 is fixed to the cavity 401. The elastic force of the third return spring 11 can push the cavity 401 to reset.

[0041] The pressing assembly 5 includes a vertical plate 501 fixed to the side of the base 1. A fixing plate 502 is fixed to the side of the vertical plate 501. A hydraulic cylinder 503 is installed on the upper surface of the fixing plate 502. A pressure plate 504 is installed at the output end of the hydraulic cylinder 503. The pressure plate 504 can be moved by the output end of the hydraulic cylinder 503. The pressure plate 504 can contact the upper mold 302 and press down on the upper mold 302, thereby causing the upper mold 302 to descend. A motor 12 is installed on the upper surface of the base 1. The output end of the motor 12 is connected to the turntable 2. The turntable 2 can be rotated by the motor 12. A one-way feed valve 13 for replenishing material is installed on the bottom surface of the cavity 401. The cavity 401 is filled with release agent. The one-way feed valve 13 can replenish the release agent into the cavity 401.

[0042] This embodiment describes a stamping die for producing stamped parts for new energy vehicles. By setting up three sets of die components 3, when one set of die components 3 is performing a stamping operation, another set of die components 3 is transferred to the finished product by the turntable 2. During the stamping process, the compression cylinder 402 discharges the release agent through the drain pipe 405 to prevent the finished product from adhering to the surface of the lower die 304, which facilitates the demolding of the finished product. The operator only needs to stand on the side away from the lower pressing component 5 and wait for the turntable 2 to transfer the die component 3 that has completed the stamping to his / her face. After taking the finished product, he / she can put on the new raw material to complete the loading and unloading. During the loading and unloading process, the lower pressing component 5 can still press down the new raw material without stopping the machine, so that the whole process can complete the loading-stamping-unloading operation at the same time, which, together with the rapid demolding, improves the overall work efficiency.

[0043] It should be noted that after the material is cut, a release agent is manually sprayed onto the bottom surface of the upper mold 302.

[0044] The working principle of the above embodiment is as follows: During the stamping operation, the raw material is placed in the lower mold 304. Driven by the turntable 2, the raw material is transferred to the lower pressing assembly 5. The hydraulic cylinder 503 drives the pressure plate 504 to descend, and the pressure plate 504 pushes the upper mold 302 to descend to complete the stamping operation. Then, the hydraulic cylinder 503 drives the pressure plate 504 to rise. Under the elastic force of the first return spring 8, the lifting plate 301 drives the upper mold 302 to rise. During the stamping operation, the raw material contacts and presses down on the pressing block 403. The downward pressure of the pressing block 403 causes the release agent inside the compression cylinder 402 to enter the lower mold 304, which facilitates the subsequent release of the finished product. When one set of mold components 3 is performing a stamping operation, another set of mold components 3 is driven by the turntable 2 to transfer the finished product. After the upper mold 302 and the lower mold 304 are separated, the cavity 401 is reset under the elastic force of the third reset spring 11. The reset of the cavity 401 ejects the finished product, completing the demolding of the finished product. The operator only needs to take the finished product and put on the new raw material. During this period, the release agent can be sprayed onto the surface of the upper mold 302. During the loading and unloading process, the lower pressing component 5 can still press down the new raw material without stopping the machine, so that the whole can complete the loading-stamping-unloading operation at the same time, which improves the overall operation efficiency in conjunction with rapid demolding.
