Abstract
The invention relates to a liquid discharge opening of a die, which comprises an internal clamping mouth sleeved to a ceramic pipe sleeve, and an arc-shaped opening towards to a filter screen, wherein the material of the liquid discharge opening is ceramic. The invention has the advantages that the usage life of the ceramic liquid discharge opening is long, the ceramic liquid discharge opening can be replaced every 30-60 days; the ceramic liquid discharge opening has good effects of riser and liquid discharge break, the core break (riser) phenomenon is not easy to generate; the phenomena of draft and aluminum viscidity generated during the casting process can be effectively reduced, the casting process is smooth; the castability is stable, the production cycle is reduced, the output is increased; the circumference of a central hole of a bottom die can be effectively protected from aluminum water corrosion, thereby the die preparation labor hour can be minimized.
