Abstract
PURPOSE:To improve high tamp. durability of a die by forming one side or both of the forming dies composing of one pair of male and female dies with material mixing the specific wt.% of oxide to Pt or Pt base alloy. CONSTITUTION:The forming dies a1, a2 composing of one pair of the male and female dies for forming cavity (a) are arranged and an injection sleeve 7 is arranged at suitable position between both dies a1, a2. Then, the one side or both of the dies a1, a2 are constituted of the material mixing one kind among the oxide of ZrO2, MgO, Al2O3, etc., at the ratio of 0-5wt.% to the Pt or Pt base alloy. As the oxide of ZrO2, etc., exists in metallic matrix as uniform and fine particles, mechanical properties of hardness, ductility value, etc., of the dies a1, a2 are improved. By insertion of the oxide together with the characteristic of Pt or Pt base alloy, heat shock resistance and stability are improved. By this method, the high temp. durability of the dies a1, a2 is improved.
