The length of slot 31 is more than the length of the second groove 32, thus just recessed first between the first groove 31 and the second groove 32
The length direction both ends of 31 bottom of slot form the step for preventing the first convex block 11 from moving down, and the first convex block 11 drops to the position
When stop movement.Further, in order to ensure that enough resistances prevent the first convex block 11 from declining, the width of the first groove 31 is big
In the width of the second groove 32, step is also formed at the width direction both ends of 31 bottom of the first groove in this way, with length direction
Step cooperatively prevents the first convex block 11 from declining.
In order to which after bead 40 is broken, 30 bottom surface of backing plate makes the second convex block 21 just when being overlapped with 20 top surface of the second punch-pin
It is completely embedded into the second groove 32, and the arcwall face 211 at the top of it is just matched with the groove 111 of the first convex block 11, this reality
The thickness for applying the second convex block 21 of example is equal to the depth of the second groove 32.
In order to reduce the molding area of the first punch-pin 10 and the second punch-pin 20, ensure the flatness of molding, the present embodiment
Backing plate 30 is equipped with annular convex platform 33 close to a side surface of the first punch-pin 10.
As preferred embodiment, first punch-pin 10 of the present embodiment, four angles of backing plate 30 and the second punch-pin 20
In there are one be fillet, remaining is chamfering；Fillet can play the role of fool proof, ensure the first punch-pin 10, backing plate 30 and the
Two punch-pin, 20 accurate fit.
As preferred embodiment, the material of first punch-pin 10 of the present embodiment, backing plate 30 and the second punch-pin 20 is equal
For isostatic pressing formed graphite.
The above embodiment is only preferred embodiments of the present invention, cannot be protected with this to limit the utility model
Range, the variation of any unsubstantiality that those skilled in the art is done on the basis of the utility model and replacing belongs to
In the utility model range claimed.
