The reason why the rubber is semi-vulcanized after injection from step 8) is to reduce the fluidity of the rubber. )
(It is possible to mold the rubber with high precision when vulcanizing and molding it into a composite by combining them), either at the temperature at which the vulcanizing agent decomposes, that is, below the vulcanization temperature, or at the vulcanization temperature. Do it in a short time.

ある。Note that the rubber may be in an unvulcanized state instead of being in a semi-vulcanized state as described above, and in this case, the rubber is easily deformed especially when demolding the preforming mold. It is necessary to improve the mold releasability by reducing the surface roughness or applying a mold release agent. Furthermore, if molded in an unvulcanized state, over 70-
If it becomes large, the unvulcanized molded shape may be deformed, so it is necessary to sufficiently adjust the amount and position of the over 70-.

The middle layer of the layers is preformed in an unvulcanized or semi-vulcanized state, and two or more layers are molded on the side of the first split mold, and these two or more layers are molded to form the first split with rubber attached. Claims characterized in that a mold and a second split mold preformed in an unvulcanized or semi-vulcanized state to which a second layer of rubber is attached are combined and vulcanized to form a composite. A method for precisely molding a multilayer rubber molded product as described in item (1).
