Abstract
The utility model discloses a drawing and forming die for a magnesium-alloy surface casing of a notebook computer, which comprises a die carrier, an upper die of which the middle part is provided with a hollow cavity and a lower die which can extend into the hollow cavity at the middle part of the upper die to form a die cavity of the surface casing of the notebook computer, wherein the die carrier is a mechanism formed by assembling an upper die holder, a lower die holder, a guide post and a guide sleeve, the upper die holder and the lower die holder can carry out relative movement along the axial direction of the guide post, the upper die is fixed on the upper die holder, and the lower die corresponding to the upper die is fixed on the lower die holder. The drawing and forming die for the magnesium-alloy surface casing of the notebook computer also comprises a hold-down ring which is sleeved outside the lower die in a sliding fit way and is also over against the lower end face of the upper die, wherein a spring of the hold-down ring is arranged between the hold-down ring and the lower die holder. When the spring of the hold-down ring is in a free state, the upper end face of the hold-down ring is higher than the working face of the lower die. Relative to a traditional rigid hold-down ring, a blank of a plate can better adapt to drawing deformation because the hold-down ring is an elastic hold-down ring. Thus, the drawing effect is better.
