The invention discloses a hub module for a segmental cooling technique structure, comprising an upper die main body, a side die main body and a lower die; the lower side of the upper die main body is provided with an upper die insert and an upper die core, wherein an upper die partitioning gap is arranged among the upper die main body, the upper die insert, and the upper die core; by using an upper die reverse water tank structure and a new technical feature of the module, the hot joint which is hard to cool between the hub and a spoke is used as a preferential cooling point to realize bidirectional feeding; the segmental cooling can shorten cycle and improve the performance efficiency.
