(54) PRESS FORMING DIES


(57) A lightweight mold for press forming is presented.
Molds (2, 32) are characterized in that design forming portions thereof, these design forming portions making contact with a workpiece at the time of press forming and thereby forming a target design on the workpiece, are constructed of rod shaped members (design forming rods (4, 34)). By having the design forming portions be constructed of rod shaped members, the weight of the mold is reduced. It is preferred that the molds (2, 32) are further provided with supporting rods (6, 36, etc.) which support the design forming rods (4, 34), these rod members constituting a framework structure.
