The transverse centering grooves and the longitudinal centering grooves are perpendicularly intersected to divide the front and back sides of the plate body into four areas, and each area is provided with a mold groove for fixing the mold and a positioning groove for fixing the pad. This solves the problem that the upper and lower mold guide pins are not concentric due to different product structures during the stamping process, affecting the stamping quality, meets the needs of rapid stamping operations of parts of two specifications, reduces the replacement time of the pad, reduces the difficulty of replacing the pad, improves the centering accuracy after mold change, and improves the stamping efficiency.

[0004] However, the above can only replace the stamping dies for parts with two specifications. However, the shapes of some product structures are inconsistent, and the process requirements of the molds are different, which leads to inconsistent spacing of the mold grooves when the molds are designed. Therefore, an automotive part stamping die changing pad that can change the spacing of the mold grooves is proposed. Utility Model Content
