  • Patent number: 8894401
    Abstract: The present invention is on injection mold with cooling and heating passage which can form cooling and heating passage close to forming space in the inside of mold body and easily design cooling and heating passage in forming space with complicated trajectory. Injection mold with cooling and heating passage consists of lower mold and upper mold forming blowed forming space by combining said lower mold on the top of said lower mold, provided that said lower mold or said upper mold consists of mold body in which forming space is created on one side so that melted resin is injected and formed; connecting groove depressed towards said forming space from the opposite side of the side with said forming space created; and sealing kit which is inserted into said connecting groove in separation from the end of forming space of said connecting groove and creates cooling and heating passage 60) in said separated space.
