Method for manufacturing fused zirconia corundum basin brick die

The invention relates to a method for manufacturing a fused zirconia corundum basin brick die. The problems of difficult molding, low yield and raw material waste of a current special fused zirconia corundum basin brick are effectively solved. The structure of the fused zirconia corundum basin brick is that an inner core is arranged at the central position of an inner die; the inner die, the inner core and an outer die are concentrically arranged in the outer die; the inner core, the inner die and the outer die are made from resin sand; an exhaust conduit and a casting conduit which are communicated with a basin brick-shaped cavity formed between the inner die and the outer die are respectively arranged on the two sides of the outer die through casting openings; an exhaust dead head is formed in the upper part of the vertical exhaust conduit; a casting dead head is formed in the upper part of the vertical casting conduit; a loosen layer is arranged on a cutting line on the upper part of the outer die; a heat-preserving dead head is formed in the loosen layer; and on the two sides of a material basin, the exhaust conduit and the exhaust dead head are symmetrical with the casting conduit and the casting dead head. The characteristic that the resin sand is naturally collapsed under a high temperature is effectively used, and the utilization combining with a water glass sand dispersing plate is realized, the yield is high, color pollution of a product is avoided, and the post processing efficiency is improved.
