Method for manufacturing honeycomb structure forming die |
摘要 |
<p>There is provided a method for manufacturing a honeycomb structure forming die including a liquid groove forming step for forming linear processing liquid grooves 3 whose width is smaller than that of the slit 5, in positions for forming the slits 5 for forming the partition walls 41 of the honeycomb structure 40 by subjecting the kneaded clay to extrusion in one side end face 7 as a kneaded clay forming face 17 of a plate-shaped die substrate 2. An introduction hole forming step for forming introduction holes 4 for introducing the kneaded clay is performed before or after the liquid groove forming step. Slits 5 communicating with the introduction holes 4 are formed by performing comb-like electro-discharge machining by a comb-like electrode 21 where plate-shaped protrusion electrodes 23 corresponding with the slit 5 width are disposed in positions including the processing liquid grooves 3.</p> |
