A sequence circuit display method for an injection molding machine which enables a sequence circuit corresponding to an operating step to be quickly displayed and enables the connection states of contacts, coils, etc. in a sequence circuit to be easily grasped when obtaining a grasp of the sequence circuit, comprising selectively inputting an operating step name in an injection molding machine from an input device to thereby display a sequence circuit including contacts, coils, etc. corresponding to the selected input operating step as a ladder diagram on a display device; comprising displaying a sequence circuit of an injection molding machine as a ladder diagram on a display device and selectively inputting one of the contacts, coils, etc. in the ladder diagram to thereby display a sequence circuit including contacts, coils, etc. corresponding to the selected input contact, coil, etc. as a ladder diagram on the display device; etc.

Sequence circuit display method of injection molding machine

Disclosed is a compression molding method comprising the steps of: calculating an average value of mold clamping forces sensed in a plurality of mold clamping mechanisms for clamping a stationary and a movable mold half; obtaining a first control signal on the basis of deviation between a preset target mold clamping force and an average value of sensed mold clamping forces; sensing positions of movable members of the mold clamping mechanisms; obtaining an average value of sensed positions; setting the average value as a successive target position; obtaining a second control signal on the basis of deviation between each of the sensed positions and the successive target position; and obtaining a clamping control signal for each of the clamping mechanisms by adding the first control signal and the second control signal. An apparatus suitable for implementing the method is also disclosed.
