a simple hydraulic control arrangement for the application in an injection molding machine a shield 40 with an attached mold half 3 u2032 is in the position of the beginning of the mold closing movement s the shield 40 is guided in 4 columns 41 and the machine frame 42 the counter mold half 3 u2033 is stationary fixed to the machine frame 42 for the molding process this example also shows a locking device 43 supporting the holding force during the injection in both the pressure and counter pressure side the hydraulic pressure is modulated with the electrical signal settings fig6 a shows a simplified velocity position profile for the injection molding machine in which b indicates the acceleration phase k the phase of constant velocity and v the deceleration phase the velocity profile shows a possible ideal trapezoid fig7 is a further detailed arrangement in which instead of the simple position logic a switchable cartridge valve bridge is used fig8 demonstrates another arrangement with pressure accumulator 50 replacing pump 8 in the main stage the pressure limiting valve 10 as used in fig5 is replaced by a pressure reducing valve 51 the remaining arrangement for the hydraulic control system with accumulator can be identical to any.
