Claim Text:
1. A hot press mold for pressing a heated workpiece, thereby molding and quenching the workpiece, comprising: a temperature measuring device configured as a stroke sensor elongating/contracting by a pressure added via the workpiece, wherein the temperature measuring device is arranged to project outward from a molding surface of the mold, and when the workpiece is in contact therewith, the measuring device contracts and goes into the mold in response to the pressure from the workpiece, wherein the temperature measuring device comprises: wherein the first elastic member is disposed at the supporter to bias the protector toward the tip end, wherein the second elastic member is disposed at the fixing portion to bias the supporter toward the tip end, wherein a spring constant of the first elastic member is smaller than that of the second elastic member, wherein the temperature measuring device elongates/contacts in two steps by the first and second elastic members, and wherein the protector is made of metal with high pyroconductivity and the protector is configured to conduct a heat of the workpiece to the thermocouple by contacting the workpiece.
