PURPOSE:To provide a forming mold for a perforated resin molding in which the resin molding having a prescribed shape is compression-molded without obstructing the flow of resin and also perforating work is performed in the mold. CONSTITUTION:Recesses 3, 4 are positioned oppositely to the perforating part of a resin molding and provided on the mold faces of both molds 1, 2. The upper faces 5a, 6a are positioned in the same faces as the mold faces in a time for compression-molding molten resin. A punch 5 having a cutting tooth 5b is equipped in the recess 3 of one side so as to freely rise and set by a driving cylinder 5c. A pedestal 6 driven by the driving cylinder of the punch 5 is equipped in the recess 4 of the other side so as to be freely deflected by a spring 6b. |
