Method for manufacturing a coolable mold structure for a molding tool for hot-working and/or for press hardening of metal sheet workpiece, involves forming insertion pipes with heat exchange performance enhancing inner walls

摘要

The method involves forming tool effective areas (112,122) of base portions (111,121). The cooling boreholes (115,125) are formed in the base portion. The insertion pipes (130) are introduced into the cooling boreholes. The insertion pipes are partially formed with heat exchange performance enhancing inner walls. The insertion pipes are formed of aluminum material. Independent claims are included for the following: (1) a method for manufacturing coolable molding tool; and (2) a molding tool.
