The invention relates to the technical field of dies and discloses an ear-hole punching die of a basin stand. The ear-hole punching die of the basin stand comprises a lower die device and at least an upper die device, wherein the upper die device comprises an upper padding plate, a pressing block, a sliding block, a male die, a guide rail and a material pressing plate; the pressing block and the material pressing plate are mounted on the lower end of the upper padding plate; the sliding block is mounted on the upper end of the guide rail; the guide rail is mounted on the lower die device; the male die is mounted on the sliding block, and the axial line of the male die and the horizontal line form an included angle; the lower die device comprises a guide rail padding plate, a lower padding plate, a female die padding plate and a female die; the guide rail padding plate and the female die padding plate are mounted on the lower padding plate; the female die is mounted on the female die padding plate and corresponds to the male die. As the structure of the sliding block type ear-hole punching die is adopted, the whole die occupies relatively small space, is suitable for production of progressive die of the basin stand, reduces cost of the progressive die and improves production precision of basin stand products.
