PRESS MOLDER AND CUSHION RING

摘要

The problem of a conventional press molder is insufficient rigidity of an annular cushion ring receiving inward force, which cannot prevent a lower portion of the cushion ring from deforming, i.e., bending and expanding outward. A press molder (1) according to the present invention comprises a die (2), a punch (3) and a cushion ring (5). The cushion ring (5) has a rib (51) which is a reinforcing structure so as to be prevented from being bent at the time of press molding, and the punch (3) is formed therein with a recess (31) which is a reinforcing structure escape part so as to prevent the punch 3 from interfering with the rib (51) of the cushion ring (5).
