Abstract
Conventional electro-hydraulic servo control system is widely used for mold oscillation, but it is difficult for this system to construct a stable, low cost and high performance control system. This paper proposes an oscillation method driven by an electro-hydraulic-controlled stepping cylinder, and the stepping cylinder has the performances of less control links, easy maintenance, relatively low cost and high precision. The mathematic model of electro-hydraulic-controlled stepping cylinder is established, and through PWM control the sine curve and non-sinusoidal curve are simulated. The result of simulation demonstrates that the model is effective, and the proposed electro-hydraulic-controlled stepping cylinder system instead of conventional electro-hydraulic servo control system is feasible.
