PURPOSE: A multi component injection mold and an injection method are provided to miniaturize the size of an injection mold by forming first and second cavities on both sides around a rotary core. CONSTITUTION: A multi component injection mold(100) comprises a rotary mold(30), a first mold(10), a second mold(20), and a rotating unit(40). An injecting groove(36) is formed at the one side and the other side of the rotary mold which are faced. The first mold is formed on the one side of the rotary mold. The first molding groove is formed on the first mold. The first molding groove forms the first cavity with the injecting groove. The second mold is united at the other side of the rotary mold. In the second mold, a second molding groove is formed. The second molding groove forms the second cavity with the injecting groove. The rotating unit rotates the rotary mold when the first mold, the second mold and the rotary mold are separated.
