Molding tool for hot forming and/or press hardening a sheet metal workpiece and method for producing a cooled tool segment

The invention relates to a molding tool for hot forming and/or press hardening a sheet metal workpiece and a method for producing a cooled tool segment. The molding tool is provided with at least onecooled tool segment (100), which is formed by a shell element (110) and a core element (120), the shell element (110) having an acting surface facing the sheet metal workpiece (112) and a pocket-likechamber (114) on the back side facing away from acting surface, in which the core element (120) is arranged. It is provided that the core element (120) is made of a material (M2) that has a higher thermal conductivity than the material (M1) of the shell element (110). The invention further relates to the method for producing the tool segment (100). 本发明涉及一种板件热成型和/或压硬化的模具和制造冷却工具段的方法，该模具带有至少一个被冷却的工具段(100)，其由壳元件(110)和芯元件(120)形成，其中，壳元件(110)具有面向板件的作用面(112)和在背对此的后侧上袋式的腔(114)，芯元件(120)布置在该腔中。设置成，芯元件(120)由材料(M2)制成，其具有比壳元件(110)的材料(M1)更高的导热能力。本发明另外涉及一种用于制造这样构造的工具段(100)的方法。
