发明名称 Die for forming honeycomb structure and method of manufacturing honeycomb structure
摘要 There is disclosed a die for forming a honeycomb structure and a method of manufacturing the honeycomb structure by use of the die, in which variations of cell pitches are suppressed in a central portion and the vicinity of an outer periphery after drying and firing an extruded honeycomb structure, and the honeycomb structure having a uniform cell pitch can be manufactured. A die 1 for forming a honeycomb structure has a front surface provided with groovy slits 2 formed between cell blocks 3 and a back surface provided with back holes 4 a communicating with the slits 2 . The die 1 has a structure in which a pitch P of the adjacent cell blocks 3 is enlarged from a central portion of the front surface toward an outer periphery in a stepwise manner.
