PROBLEM TO BE SOLVED: To provide an extrusion molding die in which the occurrence of burrs from a free end portion 279 of respective plate member 152, 153 width direction both ends of a V-shaped corner material 25, is prevented.SOLUTION: Provided is an extrusion molding die in which: the extrusion molding die 4 has, within an imaginary plane in perpendicular to the resin moving direction (in direction perpendicular to the paper plane in Figure 26), a plurality of divided die members 21,22; the middle position of the thickness in perpendicular to the resin moving direction of a flow slit 277 (in vertical direction in Figure 26) is set to be parting planes 269, 267 extending, over the outer lateral of the flow slit 277, along the flow slit 277 (from flow slit 277 toward to the right in Figure 26) and being in parallel to the resin moving direction (in perpendicular to the paper plane in Figure 26); and when the flow slit 277 wears, it is repaired by grinding the parting planes 269, 267. |
