[0020] according to Figure 1-4 As shown, this embodiment proposes a stamping die for automobile parts, comprising a supporting demoulding component 1 and a bottom film component 2, wherein the top of the inner side of the supporting demoulding component 1 is provided with a bottom film component 2 assembled with bolts, and the top of the outer side of the supporting demoulding component 1 is provided with a stamping processing mechanism 3 assembled with bolts;

[0021] The bottom membrane component 2 includes a bolt base 201, a bottom plate 202, a bottom membrane shell 203, a through sleeve strip 204, a demoulding sheet 205, and a spherical bottom head 206. The bolt base 201 is arranged at the top of the inner side of the supporting demoulding component 1, the top side of the bolt base 201 is provided with the bottom plate 202, and the bottom membrane shell 203 is arranged above the side of the bottom plate 202, the inner side of the bottom plate 202 is provided with a sleeve-connected through sleeve strip 204, and the top side of the through sleeve strip 204 is provided with a demoulding sheet 205, and the bottom of the through sleeve strip 204 is provided with a spherical bottom head 206.

[0022] The spherical bottom head 206 is a hemispherical arc-shaped protruding structure, and the bottom plate 202 and the through-sleeve strip 204 are in a through-plugging structure.

[0023] In this embodiment, when the lifting bracket 106 is lifted under the operation of the limiting telescopic strip 107, the top ball block 108 on the lifting bracket 106 acts on the spherical bottom head 206, so that the spherical bottom head 206 transmits force to the penetrating strip 204, and through the mutual cooperation of the bottom film shell 203 and the demoulding sheet 205, the product can be demoulded.

[0024] The supporting demoulding assembly 1 includes a base block 101, a bottom groove plate 102, a hydraulic cylinder 103, a connecting rod 104, a hinged rod 105, a lifting bracket 106, a limiting telescopic strip 107 and a top ball block 108. The top side of the base block 101 is provided with the bottom groove plate 102, and the inner side of the bottom groove plate 102 is provided with a connecting rod 104 connected to the output end of the hydraulic cylinder 103.

[0025] In this embodiment, when demolding is required, the stamping mechanism 3 is used to leave the processing position, and the output power of the hydraulic cylinder 103 on the inner side of the bottom groove plate 102 is started to drive the output end of the hydraulic cylinder 103 to operate, so that the output end of the hydraulic cylinder 103 can drive the connecting rod 104 to extend and retract.

[0026] The inner end of the connecting rod 104 is hingedly connected to a lifting bracket 106 via a hinge rod 105 , and limited telescopic strips 107 are arranged above both sides of the lifting bracket 106 , and a top ball block 108 is arranged on the top side of the middle part of the lifting bracket 106 .

[0027] In this embodiment, after the connecting rod 104 is telescopically operated, the hinge rod 105 at one end of the connecting rod 104 is driven by the hinge, and the lifting bracket 106 is lifted under the operation of the limit telescopic strip 107.

[0028] The stamping mechanism 3 includes an upper base 301, a lifting frame 302, a top plate 303, a hydraulic cylinder 304, a lifting plate 305, a shock absorber 306, a top cover 307, a plug pin 308 and a forming block 309. The upper base 301 is arranged above the four sides of the bottom groove plate 102, and a lifting frame 302 is arranged above the outer end of the upper base 301, and a top plate 303 is arranged on the top side of the lifting frame 302, and a lifting plate 305 connected to the output end of the hydraulic cylinder 304 is arranged on the inner bottom side of the top plate 303.

[0029] In this embodiment, when in use, the raw materials to be processed are placed in the bottom membrane shell 203 on the inner side of the bottom plate 202, and then the output end of the hydraulic cylinder 304 above the top plate 303 is started to output power to drive the output end of the hydraulic cylinder 304 to operate, and after the output end of the hydraulic cylinder 304 operates, the lifting plate 305 is lowered.

[0030] A shock absorber 306 is disposed below the lifting plate 305 , and a top cover 307 is disposed on the bottom side of the shock absorber 306 . Connecting pins 308 are disposed below the four sides of the top cover 307 , and a forming block 309 is disposed on the inner bottom side of the top cover 307 .

[0031] In this embodiment, when the lifting plate 305 is lowered, the operation of the shock absorber 306 and the top cover 307 allows the top cover 307 to be plugged and fixed on the bottom film shell 203 with the plug pin 308, and the raw materials are made into products by the cooperation of the forming block 309 and the bottom film shell 203.

[0032] The working principle of the stamping die for automobile parts is as follows: when in use, the raw materials to be processed are placed in the bottom film shell 203 on the inner side of the bottom plate 202, and then the output end of the hydraulic cylinder 304 above the top plate 303 is started to output power to drive the output end of the hydraulic cylinder 304 to operate, and the lifting plate 305 is lowered after the output end of the hydraulic cylinder 304 operates. When the lifting plate 305 is lowered, the operation of the shock absorber 306 and the top cover 307 makes the top cover 307 cooperate with the plug pin 308 to be plugged and fixed on the bottom film shell 203, and the raw materials are made into products by the mutual cooperation of the forming block 309 and the bottom film shell 203. When demoulding is required, the stamping processing mechanism 3 is used to leave the processing position, and the bottom groove plate 102 is started. The output end of the hydraulic cylinder 103 on the inner side outputs power to drive the output end of the hydraulic cylinder 103 to operate, so that the output end of the hydraulic cylinder 103 can drive the connecting rod 104 to extend and retract. After the connecting rod 104 extends and retracts, the hinged rod 105 at one end of the connecting rod 104 is transmitted through the hinge, and the lifting bracket 106 is lifted under the operation of the limit telescopic strip 107. When the lifting bracket 106 is lifted under the operation of the limit telescopic strip 107, the top ball block 108 on the lifting bracket 106 acts on the spherical bottom head 206, so that the spherical bottom head 206 transmits the force to the penetrating strip 204, and through the mutual cooperation of the bottom film shell 203 and the demoulding sheet 205, the product can be demoulded.
