Apparatus for molding honeycomb structure and molding method

A honeycomb structure molding apparatus for extrusion molding a honeycomb structure, characterized in that it has at least a spinneret provided with a back pore part for introducing a molding material and a slit part for extruding the molding material, and a press plate for fixing the spinneret, the spinneret comprises an inner side part and an outer peripheral part the inner side part is protruded to the downstream side to form a level difference part between the inner side part and the outer peripheral part, the press plate is opened opposing the inner side part of the spinneret and presses the downstream side of the outer peripheral part of the spinneret through a gap part formed between the spinneret and the press plate, and a reservoir part comprising a ring dented part is provided in the press plate at the position outside by a given length L facing the gap part from the innermost end of the face opposing the downstream side of the outer periphery part at the spinneret, both ends of the reservoir part being at the same level to each other, the press plate having a slant face to the plane of the gap part and starting from one end of the reservoir part, the slant face facing the level difference.
