Bidirectional circulating cooling plastic mold

The utility model discloses a bidirectional circulating cooling plastic mould which comprises a base, the top end of the base is fixedly connected with a lower mould, the top end of the lower mould is provided with an upper mould, the top end of the base is internally provided with an inner mould, and the bottom end in the base is fixedly connected with a hydraulic column. Two-way circulating cooling is adopted, the four walls of the inner mold are laid in a snakelike surrounding mode, the contact area is increased, the cooling effect is more uniform, the cooling efficiency is improved, the base and the inner mold are divided into two parts, the flow divider valve and the flow collecting valve are in butt joint with the other ports of the liquid injection port and the liquid outlet through the inserting ends of the movable inserting pipes respectively, and on the basis that the smoothness of a pipeline is guaranteed, the cooling efficiency is improved. The hydraulic columns drive the inner mold to ascend and
