Injection molding machine for controlling a molding process using the platen interval and clamping pressure as control variables. |
摘要 |
In an injection molding machine which comprises a mold composed of a fixed mold attached to a fixed platen and a movable mold attached to a movable platen, and a driving source for driving the movable platen to open and close the mold, a distance sensor detects, as a platen interval, a distance between two positions preliminarily selected on the fixed platen and the movable platen and produces a distance detection signal. A pressure sensor detects a clamping pressure applied by the driving source and produces a pressure detection signal. A control unit controls the driving source to adjust the platen interval and the clamping pressure through a plurality of steps in response to the distance detection signal and the pressure detection signal. <IMAGE> |
