<P>PROBLEM TO BE SOLVED: To provide a control method of the injection molding machine that can optimize the response characteristic of the falling and the rising of the holding pressure in the dwelling process, especially to provide the control method of the injection molding machine that can optimize the response characteristic of the falling of the holding pressure immediately after the start the dwelling process. <P>SOLUTION: Time between the dwelling process start time point or the time point when the size of the holding pressure can be switched and the time point when the pressure can be switched to the next holding pressure is divided into the high response section and the low response section in chronological order. In at least a part of the section in the high response section, at least one out of three settings as below is performed for the response characteristic that the operator set: a response time zero setting to set the response time to zero; a response time decrease setting to lower the response time to the value other than zero; and an opening restriction command value expansion setting to expand the opening restriction of the spool opening of the servo mechanism. <P>COPYRIGHT: (C)2013,JPO&INPIT |
