PROBLEM TO BE SOLVED: To provide a mold for molding a molding rubber, which is extremely effective for the prevention of defects due to a deficiency or the like especially when a molding rubber molded article of a large capacity is manufactured, and a manufacturing method for the molding rubber molded article using the mold for molding the molding rubber. SOLUTION: This mold 1 for molding a molding rubber is equipped with a rubber channel for the injection-supply of a material rubber having a crosslinking agent into a cavity section. In the vicinity of a gate 8 which is located right before the cavity section 7, a check valve 9 is provided. In this case, the reverse check valve 9 restricts a reverse flow of the rubber by closing the rubber channel at the time of the crosslinking reaction, without closing the rubber channel at the time of injection of the material rubber. |
