PROBLEM TO BE SOLVED: To provide a molding mold which can reduce the production cost of a vibration preventive bush. SOLUTION: The molding mold comprises a lower mold having a supporting surface 31, and an upper mold having a contact surface. The lower mold and the upper mold are respectively equipped with a lower side supporting pin 32 and an upper side supporting pin. The lower side supporting pin 32 and the upper side supporting pin are engaged in a cylindrical member 1. In a mold closing state in which the cylindrical member 1 is interposed in the vertical direction Z under pressure between the lower mold and the upper mold, a recess for forming a cavity is formed in the lower mold and the upper mold. An annular projection 43 for lower seals which are respectively in pressure-contact with a lower end surface 1K and an upper end surface of the cylindrical member 1 and the annular projection for the upper mold are respectively formed in the supporting surface 31 of the lower mold and a contact surface of the upper mold when the cylindrical member 1 is interposed under pressure between the lower mold and the upper mold to close the mold in the molding mold for molding a vibration preventive bush.
