PURPOSE: To provide a mold for resin foam capable of cooling effectively in a short time when a mold component is cooled wherein a resin molded product can be manufactured by molding and there is no fear that a slit member may move in a steam blow-in hole following the molding. CONSTITUTION: In a mold for resin foam wherein raw material beads are charged into a cavity 13 formed by a pair of freely openable molds; the beads are foamed by heating by blowing steam from a steam-blow-in hole 14; and besdies the foam after molding is cooled by making cooling water flow around, a cooling fin 17 projected by being expanded radially outside the mold is integrally connected to an open end of a slit component 15 having a plug like part 16 wherein many slits are provided on a blocked end 19 on the cavity 13 side. |
