The stamping die has effectively solved among the prior art and has set up the cooperation mould of slope, and the machining precision that leads to stamping die to require is high, and the unstable problem of stamping precision.

It should be noted that the pushing surface is disposed on an end surface facing the first mold 10. The pushing part can be arranged on the pushing structure 31 or on the sliding seat 21; when the pushing portion is disposed on the pushing structure 31, the pushing portion needs to be disposed facing the sliding seat 21, and the pushing of the sliding seat 21 is realized by the contact between the pushing portion and the sliding seat 21; when the pushing portion is arranged on the sliding seat 21, the pushing structure 31 can be provided with a plane or a recess on one side facing the sliding seat 21, when the plane is arranged, the pushing portion is arranged into a convex block, the convex block is in plane contact with the pushing structure 31, the sliding seat 21 is pushed, when the recess is arranged, the pushing portion is arranged into a convex block, the convex block is matched with the recess through the convex block to realize the pushing of the sliding seat 21, the recess and the plane can be combined, the contact area between the sliding seat 21 and the pushing structure 31 during pushing is increased, the pressure of the contact surface is reduced, and damage is avoided.

Because the pushing structure 31 is driven by the first die 10, the pushing portion is disposed on the pushing structure 31, so that the action of the pushing structure 31 can be consistent with that of the first die 10, and thus it can be ensured that the specific action of the pushing structure 31 is only related to the first die 10 and is not affected by the sliding seat 21 in the stamping process. The push rod 32 and the first elastic member 33 are configured to reset the pushing structure 31, specifically, by continuously applying the pushing force, after the pressure of the first mold 10 is released, the first elastic member 33 changes the elastic potential energy converted from compression into an elastic force, and the pushing structure 31 is reset by the push rod 32.
