[0025] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0026] As attached Figure 1 To Attachment Figure 5 As shown: This embodiment provides an automobile parts stamping die, including: an upper die 1 and a lower die 2, and also includes:

[0027] A guide mechanism 3, wherein the upper mold 1 is connected to the lower mold 2 via the guide mechanism 3;

[0028] A lubricating mechanism 4 is fixedly mounted on the top of the upper mold 1, and an end of the lubricating mechanism 4 is connected to the guide mechanism 3, so as to improve the accuracy of the guide mechanism 3;

[0029] A recovery mechanism 5, which is arranged on the outer side of the lower mold 2;

[0030] The buffer mechanism 6 is fixedly installed between the upper mold 1 and the lower mold 2 .

[0031] Specifically, a fastener 7 is fixedly installed on the top of the upper mold 1 , and the upper mold 1 is fixedly connected to the punch through the fastener 7 . An ejector hole 8 is opened at the bottom of the lower mold 2 , and the ejector hole 8 penetrates into the inner cavity of the lower mold 2 .

[0032] In this embodiment: the fastener 7 is used to fix the upper mold 1 to the punch, ensuring that the punch can accurately and stably transmit pressure to the workpiece during the stamping process to achieve stamping forming, and the ejector hole 8 is used to eject the stamped part from the lower mold 2 after the stamping is completed, so as to facilitate the removal of the stamped part.

[0033] Specifically, the guide mechanism 3 includes guide pillars 301 fixedly mounted on the top of the four corners of the lower mold 2, guide sleeves 302 are slidably mounted on the outer side of the guide pillars 301, the guide sleeves 302 are fixedly mounted in the through holes of the upper mold 1, and an oil inlet 303 is opened on the side of the guide sleeve 302.

[0034] In this embodiment: the guide mechanism 3 composed of the guide column 301 and the guide sleeve 302 ensures the precise alignment of the upper mold 1 and the lower mold 2 during the stamping process. This design can effectively prevent the mold from being misaligned during the stamping process and improve the stamping accuracy and stability. The setting of the oil inlet 303 allows lubricating grease to enter the interior of the guide mechanism 3, further reducing friction and improving the guiding accuracy and mold life.

[0035] Specifically, the lubrication mechanism 4 includes a lubricating grease storage box 401 fixedly installed on the top of the upper mold 1, and the lubricating grease storage box 401 is fixedly connected with a delivery pipe 402 on all four sides, and the end of the delivery pipe 402 is fixedly connected with an oil drip nozzle 403, and one end of the oil drip nozzle 403 is connected to the oil inlet 303.

[0036] In this embodiment: the lubrication mechanism 4 drips the lubricating grease evenly into the oil inlet 303 of the guide mechanism 3 through the lubricating grease storage box 401, the delivery pipe 402 and the oil dripping nozzle 403, thereby realizing real-time lubrication of the contact surface between the guide column 301 and the guide sleeve 302. This design can significantly reduce the friction of the guide mechanism 3, improve the guiding accuracy, and at the same time extend the service life of the mold.

[0037] Specifically, the recovery mechanism 5 includes a storage ring 501 fixedly installed on the top of the lower mold 2, the storage ring 501 is sleeved on the outside of the guide column 301, an oil drain hole 502 is opened on one side of the storage ring 501, the end of the oil drain hole 502 is fixedly connected to an oil drain pipe 503, and the end of the oil drain pipe 503 is fixedly connected to a recovery box 504.

[0038] In this embodiment: during the lubrication process, excess lubricating grease will slide down the guide column 301 into the storage ring 501, and flow into the recovery box 504 through the oil drain hole 502 and the oil drain pipe 503. This design can effectively recycle the lubricating grease, reduce waste, and reduce production costs.

[0039] Specifically, the buffer mechanism 6 includes a telescopic rod 601 fixedly installed on the top of both sides of the lower mold 2, a sleeve 602 is sleeved on the outer side of the top of the telescopic rod 601, a spring 603 is sleeved on the outer side of the telescopic rod 601, the top of the sleeve 602 is fixedly connected to the upper mold 1, and the spring 603 is located between the sleeve 602 and the lower mold 2.

[0040] In this embodiment: the buffer mechanism 6 can not only significantly improve the service life and stamping quality of the mold, but also alleviate the impact force of the upper mold 1 and the lower mold 2 during the stamping process to prevent damage to the mold. When the upper mold 1 is stamping downward, the sleeve 602 will compress the spring 603 to produce a buffering effect. When the upper mold 1 is reset upward, the spring 603 will release energy to push the sleeve 602 and the upper mold 1 to reset.

[0041] The working principle and use process of this utility model:

[0042] First, place the automotive parts material to be stamped at the appropriate position of the lower mold 2 and ensure accurate positioning. The punch is fixedly connected to the upper mold 1 through the fastener 7. The stamping machine drives the upper mold 1 to slide down along the guide column 301 to start the stamping process. During the stamping process, the lubricating mechanism 4 drips lubricating grease into the oil inlet 303 of the guide mechanism 3 to reduce the friction between the guide column 301 and the guide sleeve 302 and improve the guiding accuracy. During the lubrication process, excess lubricating grease will flow into the storage ring 501 along the guide column 301, and flow into the recovery box 504 through the oil drain hole 502 and the oil drain pipe 503 to achieve the recycling of lubricating grease. At the same time, when the upper mold 1 moves downward for stamping, it will drive the sleeve 602 to compress the spring 603 to produce a buffering effect. When the upper mold 1 moves downward to the predetermined position, after the stamping is completed, the spring 603 of the buffer mechanism 6 releases energy to push the upper mold 1 to reset. Subsequently, the ejector pin ejects the stamped part from the lower mold 2 through the ejector pin hole 8.
