摘要： 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.

摘要： A die 1 for forming the honeycomb structure includes: a plate-like die main body 4 including an introducing portion 3 provided on the side of one surface thereof and having a plurality of back holes 7 and a forming portion 2 provided on the side of the other surface thereof and having slits 6; and a back plate 5 detachably attached to the surface of the introducing portion 3 and having a plurality of through holes 9 connected to the back holes 7 of the introducing portion 3. Through hole opening portions 12 of the through holes 9 formed in the back plate 5 in the one surface of the die main body have such an enlarging shape as to enlarge toward the one surface of the die main body. The die 1 for forming the honeycomb structure can decrease the resistance of a forming material during extrusion.
