Fast prototyping approach in design of new type high speed injection moulding machine.

In paper is outlined an application of PExSim - a package for simulation and research dynamic control systems, for investigation a solution of very fast, hydrostatic positioning of a form in high speed moulding machine (HSIM). This construction, based on new locking mechanism, shall attain a 1s dry cycle time for form mass of 3000 kg and 0.5m distance of positioning. Complex mechanism of highly nonlinear transmission ratio, is moved by a set of hydraulic plunger cylinders, that are supplied by a constant stroke, small inertia pump, driven by very dynamic electric motor. Different limitations of final construction have induced many constraints at control. The design of locking mechanism and final control program was developed by many experiments performed by SimulationX and PExSim. Some expected transients of the mould control will be presented.
