[0001] The utility model relates to the technical field of automobile parts processing, in particular to an automobile parts stamping die. Background Art

[0002] As the foundation of the automotive industry, auto parts are essential for supporting the sustainable and healthy development of the industry. Stamping dies are required for the processing of auto parts. However, traditional stamping dies do not have the function of limiting the punch head. The punch head is usually driven by a cylinder. When the staff inspects or maintains the lower mold, if the cylinder fails or the switch is touched by mistake, it is easy for the punch head to drop, which seriously increases the occurrence of safety hazards and reduces safety. Based on this, China Patent Publication No. CN220920654U discloses an auto parts positioning stamping die. This patented technology achieves the effect of limiting the punch head through the mutual cooperation of a fixed groove, a forward threaded rod, a reverse threaded rod, a threaded block, a moving block, a movable plate, a slide, a stabilizing block, a slide plate, a support block and a limiting plate. When the staff inspects or maintains the lower mold, it can avoid the phenomenon that the punch head easily drops when the cylinder fails or the switch is touched by mistake, thereby reducing the occurrence of safety hazards and improving safety.

[0027] The use process of the present utility model is as follows: first, a person can place the stamping part on the stamping lower die 300, and then start the hydraulic device 200, so that the hydraulic device 200 drives the upper die mounting plate 210 to move downward through the output shaft, so that the upper die mounting plate 210 can drive the stamping upper die 230 to move up and down, so that the stamping upper die 230 can cooperate with the stamping lower die 300 to stamp the part;

[0028] When the stamping is completed, the personnel can power on the second oil pump 420. After the second oil pump 420 is powered on, it can absorb the hydraulic oil stored in the hydraulic oil storage tank 400 through the suction pipe, and then transport it to the sleeve rod 431 through the second oil delivery pipe 421. The hydraulic oil will push the hydraulic piston 433 upward, so that the hydraulic piston 433 can push the sliding rod 432 upward, thereby pushing the ejector plate 310 out of the embedded groove and ejecting the stamping part from the stamping lower die 300. The personnel The stamping part can be removed from the stamping lower die 300. After the removal is completed, the personnel can turn off the second oil pump 420 and then start the first oil pump 410, so that the first oil pump 410 can absorb the hydraulic oil in the ejector rod component 430 through the first oil pipe 411 and transport it back to the hydraulic oil storage tank 400 for storage. The spring 434 will cooperate with the negative pressure in the sleeve rod 431 to retract the sliding rod 432 into the sleeve rod 431, so that the ejector plate 310 can be retracted into the embedded groove, and then the next stamping can be carried out.
