型締行程へ移行１−る。Alternatively, the back pressure may be applied by maintaining the drive current of the servo motor M1 at a constant value and performing 1-lux control of the servo motor M1. In this way, when the screw 8 retreats and the position detector detects the control point L3 (step 115), the drive of the motor M2 is stopped and the four valves 20 to be turned off are made inoperative.
Conduit 13. Steps 116 and 117)
, 1tfji process is completed. Next, timer T is constant +t;S 1. jl T 2 have elapsed and the molded product has been sufficiently cooled (step 118), the cutoff valve 19 is moved to the right position, and the servo motor M1 is driven (step 1).
19,120>. Then, the piston A1 becomes
The oil is transferred to line L4. Pass through L2 and move the piston C1 of the mold clamping hydraulic cylinder C to the left in FIG.
The movable platen 3 is moved to the left via the gluing mechanism 1, and the mold 5 is moved to the left.
Open up. Then, when the position detector 1]1 reaches the opening end point L4, the servo motor M1 is stopped (steps 121, 122).・Since the oil is stored in the reserve tank 22 via pipe 1-1, one switching valve, and pipe L5, next, open the valve 21, reset the timer to 1, and start from star 1 to Zazerudoku Step 123),
The oil is returned to the driving hydraulic cylinder A via the relief valve 21 and the pipe L4, and the piston A1 moves to the right in FIG. 124), the process returns to step 101 and subsequent mold clamping steps.
