摘要
Provided is a die for extrusion forming for extrusion forming of a honeycomb formed body comprising a honeycomb forming die having a structure that there is provided at a surface a groove-like slit in a form of a cell block as well as there is provided at a backside a clay introduction hole in communication with the slit, and a frame-shaped presser plate that is disposed at an outer peripheral portion of the honeycomb forming die and that regulates a shape and dimension of a honeycomb formed body. Among the cell blocks, in an extrusion direction of forming clay, a cell block which end face is positioned to be overlapped with an inner circumferential surface of the presser plate is formed to be shorter than the other cell blocks resided inside the inner circumferential surface of the presser plate.
