Abstract

The object of the invention is a hot-forming tool () having an upper die and a lower die (), the upper as well as the lower die () each consisting of a base plate () having a forming cheek () fixed thereto and a core () which is also fixed to the base plate (), and a duct system () for the guiding-through of a coolant being constructed between the core () and the backside of the forming cheek () facing the core (). In this case, at least the forming cheeks () are constructed as cast parts. As a result of this manufacturing method relating to the forming cheeks () (? translator), the manufacturing costs of the hot-forming tool () can be significantly lowered because a high-expenditure mechanical cutting machining of the forming cheeks is only still required in the area of the mounting surfaces () as well as the mutually facing exterior sides ().
