Warm forming die structure

The invention provides a warm forming die structure which comprises a first insert, a second insert, a third insert, a fourth insert, a base assembly and fastening assemblies, and the first insert, the second insert, the third insert and the fourth insert are connected through the fastening assemblies. The bottom of the first insert, the bottom of the second insert, the bottom of the third insert and the bottom of the fourth insert are all installed on the base assembly through fastening assemblies. The invention has the following beneficial effects: the warm forming die needs to be rapidly cooled in the production process, a cooling pipeline is arranged in the die, and a plurality of insert structures are generally required to be designed due to factors such as processing limitation and manufacturing cost. According to the scheme, a plurality of inserts can be connected and fastened into a whole. And the joint of the two inserts is locked by the bolt, so that the sealing performance of the cooling water chan
