PROBLEM TO BE SOLVED: To provide a mold for extrusion molding capable of uniformly supplying a molding raw material passed through a raw material supply hole to entire slits.SOLUTION: Provided is a mold for extrusion molding where a large number of cells are juxtaposed in a longitudinal direction by partitioning them with cell walls, and used to form a honeycomb molded body whose cell wall thickness is 0.21 mm or less includes: a first surface; a second surface formed on the opposite side thereof; a raw material supply part having first through-holes formed from the first surface toward the second surface; and a molding part having second through-holes formed to communicate with the first through-holes from the second surface toward the first surface. The second through-holes when viewed from the second surface have a lattice shape made of slits, and the first through-holes when viewed from the first surface are disposed between intersection points in each slit.SELECTED DRAWING: Figure 1 |
