[0003] The Chinese patent authorization announcement number: CN220560294U provides a stamping die for automobile parts. After the blank is stamped in the groove, this patent pushes the push plate on one side of the lower pressure plate, and the push plate applies an extrusion force to the push rod and the first extrusion plate, so that the first extrusion plate pushes the limit rod to move into the movable groove, and then the stripping plate moves upward under the elastic action of the first spring in the placement groove, and the extrusion force of the stripping plate on the blank makes the blank loose in the groove, so that it is convenient to take the blank out of the groove, which solves the problem that after the existing stamping die stamps the burr, the blank is subjected to the impact force of the upper pressure plate and the boss, so that the side of the blank is close to the inner wall of the groove opened by the lower pressure plate, and it is not convenient to take the blank out of the groove, resulting in greater difficulty in demolding the blank.

[0004] In the existing technology, when stamping automobile parts, since most automobile parts are made of metal, there will be a certain amount of noise during stamping. Due to the lack of sound insulation components, the noise generated by stamping will cause noise pollution. In addition, in the stamping workshop, the noise will affect the mood of the workers, which is not conducive to the physical and mental health of the workers. Therefore, it has certain limitations when used. Utility Model Content

At the same time, the extrusion block 192 will also slide inside the L-shaped groove 22. In this process, because the limit block 14 is clamped in the limit hole 15, as the sound insulation door 11 swings, the edge of the limit hole 15 will gradually squeeze the limit block 14. Because the limit block 14 is an arc-shaped structure, the limit block 14 is After being squeezed, the positioning block 14 will slide toward the inside of the circular hole 12. When the positioning block 14 is completely separated from the inside of the limiting hole 15, the end of the positioning block 14 will fit with the inner wall of the slide groove 21. At this time, the No. 1 spring 13 is in an elastically compressed state. When the end of the squeezing block 192 gradually slides to the bottom end of the swing rod 23, it will squeeze the swing rod 23. When the end of the swing rod 23 is squeezed, the swing rod 23 will rotate counterclockwise. Because the connecting block 25 is located inside the swing rod 23, the swing rod 23 will squeeze the outer wall of the connecting block 25. At this time, the stamping plate 29 is The mounting plate 24 will slide in the direction of the soundproof door 11. When the stamping plate 29 slides, the No. 2 spring 28 will be stretched. When the sliding block 16 slides to the bottom of the slide groove 21, the stamping plate 29 slides to the maximum value. At this time, the No. 2 spring 28 is also at the maximum value of the stretched state. When the stamping plate 29 extends from the inside of the box body 1, the user can place the automobile parts to be stamped on the top of the lower mold 191, and then pull the handle 17 upward to make the soundproof door 11 close the box body 1. During the resetting process of the soundproof door 11, because the limit block 14 is a circular arc structure, when the soundproof door 11 is After 11 is reset, the centers of the limit hole 15 and the limit block 14 are on the same straight line. At this time, the No. 1 spring 13 in the elastic compression state rebounds and pushes the limit block 14 to the inside of the limit hole 15. In addition, during the reset process of the soundproof door 11, the No. 2 spring 28 in the tension state will also gradually reset. When the No. 2 spring 28 drives the stamping plate 29 to reset, the lower mold 191 is located directly below the upper mold 19. Then the user starts the hydraulic cylinder 18.
