Abstract (en)
[origin: DE19820934A1] The balancing cylinder (30') is located on the central axis (a-a) of the machine and the hydraulic cylinders forming the clamping (D) and tool closing (F) units lie on a vertical plane (v-v) through the central axis. Preferred Features: An ejection unit cylinder (40) is coaxial to the balancing cylinder (30') and the cylinder (31) of the balancing cylinder carries the ejector unit piston (41). Several ejector units may be symmetrically arranged around the balancing cylinder and are operated in conjunction with the ejector using a bridge. Tool closure (F) and ejector (A) drive units may alternatively be electromechanically driven.
