PURPOSE:To provide FRP molds capable of reducing the occurrence of a phenomenon of entrapment of air within the molds at the time of clamping the molds without reducing the function intrinsic to shear edge portions and capable of improving production speed. CONSTITUTION:A shear edge portion 10 of one 1 of molds is formed at right angles with the direction of the opening/closing operation of the molds 1, 2 and formed out of a plurality of blocks 11 which are movable in a direction in which said shear edge portion 10 approaches or is separated from a shear edge portion 20 of the other mold 2 provided with wedge portions 211a, 211b which are in contact with each block 11 at the time of opening/closing the molds 1, 2 and which allow each block 11 to be deviated in a direction in which the shear edge portion 10 approaches or is separated from the shear edge portion 20 in synchronism with the closing or opening operation of the molds. |
