[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: This kind of stamping die assembly for an automotive instrument skeleton with a guiding mechanism not only improves the guiding ability, but also improves the clamping stability and convenience of the stamping die.

[0014] (1) By installing the first guide rod between the support bottom plate and the top plate, and similarly, the second guide rod is located between the support bottom plate and the top plate. After the cylinder works, it can drive the hydraulic telescopic rod to form a hydraulic telescopic operation. Therefore, the connecting plate can move up and down. Since the guide sleeves are fixed at both sides of the connecting plate, the guide sleeves will form a guiding movement along the first guide rod. During the movement, the embedded groove and the ball cooperate to form a rolling protection. And the second guide rod penetrates through the side guide plate. Therefore, when the connecting plate moves, the first buffer spring is correspondingly compressed and rebounded. Therefore, the overall guiding ability is preferably improved during the working process.

[0015] (2) By fixing the fixed column above the support base plate and on the side of the lower die, when the connecting plate moves downward, the upper protection is formed by the protection plate. After that, while the second buffer spring is compressed, the adjusting rod moves in the installation slot, and during operation, the guide block and the guide rail cooperate for guiding, thus protecting the normal operation of the clamping plate. After starting the first telescopic rod to work, it can push the lateral position adjustment of the clamping plate. Therefore, the clamping plate and the protection pad cooperate to firmly clamp the outer wall of the lower die, thereby better improving the overall clamping stability during the working process;

[0016] (3) By fixing the positioning column on the top of the support base plate, and the bottom of the lower die is equipped with a connecting base plate, and reserved holes are opened on both sides of the connecting base plate. Therefore, during assembly, the positioning column passes through the reserved holes for positioning, and then a locking nut is used to complete the assembly above the connecting base plate outside the positioning column. The upper die is assembled below the connecting plate in the same way, thereby facilitating the assembly and replacement of the lower die during the working process.
