[0002] A Chinese patent with publication number CN217550948U discloses an automobile part stamping die with a guide structure, comprising a lower fixing seat and an upper fixing seat, wherein the upper fixing seat is arranged directly above the lower fixing seat, lower connecting blocks are fixedly connected on both sides of the lower fixing seat, upper connecting blocks are fixedly connected on both sides of the upper fixing seat, a groove is provided on the surface of the lower connecting block, bolts are fixedly connected inside the groove, a through groove is provided in the middle of the upper connecting block, and a guide column is provided between the lower connecting block and the upper connecting block. The utility model provides a guide column, which can guide the upper fixed seat and the stamping upper die to be pressed downward, so as to prevent the position of the upper fixed seat from being offset during the pressing process, which is beneficial to improving the mold closing accuracy. A first buffer spring is provided between the lower connecting block and the upper connecting block. When the first buffer spring is compressed and contracted, the pressing speed of the upper fixed seat and the stamping upper die can be reduced, which is beneficial to the upper fixed seat and the stamping upper die being pressed downward slowly, thereby improving the mold closing stability. In the automobile part stamping die with a guide structure in the application, the sleeve of the upper connecting block on the upper fixed seat slides on the guide column to guide the upper fixed seat to slide. After being used for a period of time, a distance will be generated between the hole on the upper connecting block and the guide column, which affects the stability of the guide.
