Method for the process control of a pressure diecasting machine and an apparatus for carrying out the method |
摘要 |
A method for the process control of a pressure diecasting machine, consisting of casting equipment (2) and a casting drive system (1), and an apparatus for carrying out the method are proposed. In order to regulate the movements both of the ram or drive plunger (8) in the pressing cylinder (7) and of the multiplier plunger (17) in the multiplier device (15) in each phase of the casting process, stepless devices (30, 31) measuring displacement and speed to determine the position or movements and also quick-adjustment servo-proportional valves (33 to 36) to regulate the movement both of the ram (8) and of the multiplier plunger (17) are provided.
