Abstract

A thermoforming press for forming and hardening metal sheets includes an upper die and a lower die. At least one of the upper and lower dies has a mold jaw and a support jaw which are movable relative to one another between a first position in which the support jaw rests against the mold jaw to block a flow of coolant between the mold jaw and the support jaw, and a second position in which the support jaw is spaced from the mold jaw by a distance to define a cooling gap for coolant to flow between the mold jaw and the support jaw.
