PROBLEM TO BE SOLVED: To solve the problem wherein, in the conventional mold for extrusion molding, when molding conditions or the like changes, it is necessary to manufacture a new mold in each case and it cannot be possible to flexibly cope with the change of molding conditions or the like. SOLUTION: The mold for extruding molding 10 by this invention comprises: a cylinder 11 which makes a cylindrical shape; a plug 16 which is detachably insertion fitted to the longitudinal direction base end side of a through hole 11a of the cylinder 11; a plastic dispensing piece 17 in which the base end side is located in the through hole 11a of the cylinder 11 and is exchangeably connected with the head end of the plug 16 and which defines a plastic feeding channel 22 between the inner circumference surface of the through hole 11a of the cylinder 11; a dies 14 which is exchangeably connected with the longitudinal direction head end of the cylinder 11; and a nozzle tip 12 which is exchangeably connected with the longitudinal direction head edge side of the plastic dispensing piece 17 and defines an annular plastic extruding opening 35 between the inner circumference surface of the through hole 31a of the dies 14.
