Abstract

PURPOSE: To efficiently provide a plastic forming die of a desired shape by a method wherein a superplastic alloy is shaped into a die core by plastic deformation, and the external form of the alloy block is finished by after-machining.
CONSTITUTION: When producing a die 13 for forming a formed plastic article A having ribs 1aW1h on the inner side, hobs 3aW3h coincident in shape with the ribs 1aW1h are fixed to a base plate 2 together with spacers 4aW4i to form a core forming hob master B. A block of a superplastic alloy such as Zn-Al alloy is put in the hob master B, and pressure-formed by a press ram to obtain a press forming core 12. The core 12 is then subjected to after-machining such as mechanical machining or electrical discharge machining to obtain a plastic forming die 13 of a desired shape.
