<p>A guidance system (11) on which a carriage (12) slides, is arranged in the mold (2) body (2a, 2b). Seals (4, 5) contain the filling- and applied pressures at the ends of the workpiece. The carriage is moved by a drive system (13, 15) separate from the guidance. This (13, 15) has a coupling to the carriage (12) which transmits no transverse forces. The guide is arranged in the body of at least one mold body component. Each end of the workpiece is associated with such a guidance system, carriage and drive system. Guides (11) are arranged in the plane of mold separation (TE). They extend through the mold, from one end of the workpiece to the other. The guide comprises two or more rods (11) which are parallel outside the mold. They are surrounded by the carriages (12). The drive system or at least its holder (14) and the lower mold section (2a) are arranged on a common baseplate (6). A transverse closure pressure (P) is applied to the upper section (2b) of the mold. Closure pressure is applied by a drive, connected via a machine frame to the common baseplate. Transverse force-free coupling is made between the drive system and carriage. An implementation of this coupling comprises roller (17) and/or ball bearings between contact surfaces (15a, 12a) of the drive system. These reduce friction, minimizing transmission of transverse forces acting horizontally and vertically.</p> |
