<p><P>PROBLEM TO BE SOLVED: To provide an ejector control device capable of easily setting an ejector operation pattern. <P>SOLUTION: The ejector operation pattern comprises a plurality of steps. Each of the steps comprises the following elements: a starting condition S(i) of the step; a delay timer T(i) for setting a delay time from after the establishment of the starting condition; a target arrival position P(i); and a moving velocity V(i). Data for these elements of each step and an operation sequence are set. During the operation of the ejector, after the establishment of the starting condition S(i), the ejector is driven at the set velocity V(i) up to the set target arrival position P(i) after the lapse of the time set by the delay timer T(i), and the respective steps are sequentially performed. A step, in which the starting condition S(i) is set not to exist, is the step of starting to be performed immediately after the completion of the previous step. The ejector operation pattern can be easily set even if a mold and a resin are changed. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
