The utility model discloses an extrusion mold of a window frame. The extrusion mold comprises a mold body, and a mold core and a shunt cone which are located in the mold body, wherein the shunt cone is connected with the mold core, the mold body comprises a connecting template, a shunt template, a compression molding template and a mouth template which are connected in sequence, and the mold core is integrally connected with the shunt template through multiple connecting ribs. The extrusion mold has compact structure, so that possibility of generation of a step in a cavity runner during an assembly process of a compression section and a molding section can be avoided; the mold core is integrally connected with the shunt template through multiple connecting ribs, so that adjustment and assembly are unnecessary, and the structural stability is good.
