The traditional production method of the front rod clamp mostly adopts a combination of multiple processes, including cutting, stamping, bending, etc. It not only has a complex process, but also is difficult to ensure the consistency and accuracy of the product. Therefore, it is particularly important to develop a front rod clamp stamping die.

[0015] (2) When the upper mold moves downward, it drives the guide cylinder to move downward, so that the guide cylinder slides downward on the outer wall of the guide rod, and the movement amplitude of the upper mold can be limited to reduce the phenomenon of deviation during the downward movement of the upper mold, thereby ensuring the stamping accuracy of the front rod clamp workpiece when the stamping die is used.

[0016] (3) When the upper mold moves downward, it drives the upper limit post to move downward synchronously. When the bottom of the upper limit post touches the top of the lower limit post, the continuous downward movement of the upper main mold core and the upper auxiliary mold core can be initially blocked. And when the top of the guide rod abuts against the top of the upper template, the continuous downward movement of the upper main mold core and the upper auxiliary mold core can be blocked again, thereby effectively reducing the phenomenon of pressure damage to the front rod clamp workpiece caused by the upper main mold core and the upper auxiliary mold core, and thus ensuring the integrity of the front rod clamp workpiece.
