Control device of an injection molding machine

摘要

An injection molding machine includes a molding machine controller having a computer function to perform molding by controlling a mold clamping device that clamps a mold and an injection device that injects and charges resin, plasticized and molten by rotation of a screw inside a heating cylinder, into the mold by advancement of the screw. The molding machine controller includes a mode selecting function that selects either of two modes of an injection side setting priority mode for injecting and charging the resin by giving priority to a molding condition set on the injection device side and a mold clamping side setting priority mode for injecting and charging the resin by giving priority to a molding condition set on the mold clamping device side. A setting screen display function for displaying an injection side priority setting screen and displaying a mold clamping side priority setting screen is provided.

1. A control device of an injection molding machine comprising:
a molding machine controller having a computer function to perform molding by controlling a mold clamping device that clamps, including opening and closing a mold and an injection device that injects and charges resin, plasticized and molten by rotation of a screw inside a heating cylinder, into the mold by advancement of the screw, wherein the molding machine controller comprises: a mode selecting function that selects either of an injection side setting priority mode or a mold clamping side setting priority mode, the injection side setting priority mode being for injecting and charging the resin by giving priority to a molding condition set on an injection device side selected from the group consisting of an injection velocity setting, a measurement setting, a limit pressure setting, a velocity-pressure switchover point setting and a dwelling force setting, and the mold clamping side setting priority mode being for injecting and charging the resin by giving priority to a molding condition set on a mold clamping device side selected from the group consisting of a limit velocity setting, a plasticization setting and a molding injection pressure setting, and a setting screen display function for displaying on a display, an injection side priority setting screen corresponding to the injection side setting priority mode when the injection side setting priority mode is selected, and a mold clamping side priority setting screen corresponding to the mold clamping side setting priority mode when the mold clamping side setting priority mode is selected, and when the mold clamping side setting priority mode is selected, a graph data display unit having a time axis as a horizontal axis, and a graph data display unit having a position axis as the horizontal axis are displayed simultaneously on two sections of the display, one above the other, thereby enabling property data changes of the resin at a time of molding to be displayed as waveforms with respect to the time and a position, while making a comparison therebetween, so that fine adjustments to optimize the molding conditions on each of the injection device side and the mold clamping device side is able to be made, change data of a parting opening amount Lm of the mold is able to be monitored, and data analysis is able to be performed.
