らんとすることにある。The present invention has been made in view of the above points, and an object thereof is to provide an upper die outer member which is sandwiched and fixed by a lower die blank hold part in a stage before work press working placed on a lower die. By taking appropriate measures for the above, while the work is being fixed by the upper die outer member, that is, during the press working by the upper die inner member, it is possible to perform welding on the work waiting in order to be ready for the next press working. It is to reduce the molding cycle time by the time required for the welding work as compared with the case where the welding work is performed separately from the pressing work.
