Abstract
In an apparatus for molding particularly a tubular blank of a ductile metal with internal high pressure in a mold having a cavity, which apparatus has a pressure-medium connection, which can be advanced from one base (10) and can be applied tightly against the one end of the tubular blank and a seal or a second pressure-medium connection, which can be advanced from a second base (11) and can be applied tightly against the other end, the mold or the pot (3) accommodating the mold has a circular cross section in the horizontal plane and, starting from the two bases (10; 11) with two tie rods (25; 26), a yoke (28; 29) is placed about the mold or the pot (3) and one (11) of the two bases can be moved on an arc (14) about the vertical axis (12) of the mold or the pot (3) and can be fixed at different places. The yokes (28; 29) are divided in two symmetrically to the horizontal sectional plane of the pressure-medium connection or seal assigned to them, the one yoke (29) lying in the other (28) and the connections (7; 8) of the pressure-medium connection and the seal or the second pressure-medium connection protruding with their bases (10; 11) in each case between the two parts of the oth…
