Closure device for transverse impact extrusion of components has ring piston nitrogen gas pressure springs between mold parts and support plates

摘要

The device has two relatively moveable press dies (10,20), and a two-part mold (14,24), moving relative to the press dies. The mold parts are held on two support plates. A first ring piston nitrogen gas pressure spring (22) is located between the first mold part (24) and the first support plate (18), and/or a second similar spring (12) is located between the second mold part (14) and the second support plate (6). Both springs are coaxial to the die axis.
