PROBLEM TO BE SOLVED: To prevent deposit in a branched position of piping or a route of piping or a bent route and to eliminate a mixture with a gelatinized material or a change of an injecting amount by forming a portion or all of a mold route except the piping, injection molding machine route and a molding space in which reactive liquid is fed through of a curing inhibiting substance of an addition type liquid-like silicone rubber. SOLUTION: A two-liquid addition type liquid-like silicone rubber having relative difficulty in curing and gelatinizing and good stability at an ambient temperature is molded by a two-liquid injection machine having a constant quantity transporting apparatus 1, a two-liquid mixer such as a static mixer 2 or the like, a cylinder and a screw 3 of an injection molding machine. In the mold 4, a rubber for receiving an injection port of the machine and a thermosetting resin injection gate connected to a molding cavity are disposed at one of split molds. A silicone rubber raw material passage route from the mixer 2, the runner to the gate has a water-cooled jacket, water is fed to prevent curing or gelatinizing. Thus, curing adherence on a tube wall is prevented, and an unevenness of molding or mixture of cured gelatinized material with the molding can be prevented.
