Preferably, the punch hole length direction is in the axial direction of the die.

Preferably, the mold comprises a positioning groove, and the positioning groove is matched with the valve core switch positioning lug and is positioned at the end head of the mold.

Preferably, the number of the positioning grooves is two, and the positioning grooves are symmetrically distributed on two horizontal sides of the end head of the mold.

Based on the purpose, the invention also provides a valve core, which comprises a hexagonal cap, a flange plate, threads, a pair of symmetrically distributed switch positioning lugs, a pair of symmetrically distributed ceramic still positioning grooves and a pair of symmetrically distributed water outlet holes, wherein the water outlet holes are manufactured according to the stamping method.

Preferably, the length direction of the water outlet hole is in the axial direction of the valve core.

Preferably, the distance between the water outlet hole and the ceramic still piece positioning groove is 1.5 millimeters.

Based on the purpose, the invention also provides a water faucet comprising the valve core.

Compared with the prior art, the invention has the following beneficial effects:

1. the invention adopts the stamping process for punching the stamping die, has high processing speed, small cutter abrasion and negligible burr.

2. The invention changes the hole opening direction of the water outlet hole of the valve core from a radial transverse hole to an axial vertical hole, changes the punching surface from a large curved surface to a nearly planar small curved surface, has uniform punching force, is easier to punch products, and greatly reduces the deformation generated during punching.

3. The invention changes the position of the water outlet hole of the valve core from the original cross section of the center of the positioning groove of the ceramic still piece to the position beside the positioning groove, approaches the positioning groove as much as possible, but does not wash the positioning groove. The positioning of the ceramic stator is not influenced, and the water yield of the product is ensured to be not reduced.
