Abstract
PURPOSE:To make it possible to realize stable dwelling process by a method wherein the detection value of the hydraulic pressure of an injection hydraulic cylinder is integrated with respect to time with the lapse of time so as to bring the dwelling process to an end by comparing the integral value with the pre-set predetermined value. CONSTITUTION:A hydraulic pressure sensor 13 as the detecting means of the hydraulic pressure in an injection hydraulic cylinder 12 is provided on the hydraulic cylinder 12 so as to start the detection at the starting time point of dwelling process. The detection value obtained from the hydraulic pressure sensor 13 or the analog signal of the hydraulic pressure in the cylinder is inputted in an integrator 14 in order to continuously integrate the detection value with respect to time with the lapse of time from the starting time point of the dwelling process. when the integral value outputted from the integrator 14 is equal to the predetermined value after the continuous comparison with each other, an incidence signal is outputted to a control device 17. Upon receipt of the signal, the control device 17 issues a signal for the dwelling process to be brought to an end to an injection molder.
