PURPOSE:To control injection to the speed meeting desired injection conditions by selecting and commanding a high injection speed and one pattern among patterns for increasing or decreasing, and a pattern for maintaining the speed invariable in the latter half of a high speed range. CONSTITUTION:A high injection speed V4 is set by a setter 17 and the time T required until the point B for changing the injection speed is attained from the point A for changing over to the high speed injection is set by a timer 18 for changing the injection speed at the terminal end of the high speed injection. Any one pattern among patterns III, IV for increasing or decreasing the speed and a pattern V for maintaining the speed invariable is selected by a commander 19 for the pattern for changing the injection speed at the terminal part of the high speed injection. |
