## HILMA - STARK Issue 8-17 E Application Double-acting wedge clamp for clamping moulds and dies on a press bed or ram or in injection moulding machines, machines and installations. Description The wedge clamp consists of a hydraulic block cylinder and a piston guided in a housing. The clamping bolt is provided with 20° bevel to clamp on the tapered clamping surface of the mould/die. Based on the internal design of the wedge clamp and the 20° bevel of the clamping bolt, the system is providing internal friction. Cooling circuit In addition, there is a cooling circuit for oil cooling in the...
