Problems solved by technology
That is, if the coordinate input device installed in the display device stores all the coordinate point data when the operator reads the coordinate points continuously drawn and input one by one, there will be a problem that the storage capacity will increase.
In addition, regarding the position or time as the coordinates on the horizontal axis, if the coordinates of the points are read at predetermined intervals, if the interval is large, the capacity for storing the coordinates of the points becomes small. Another problem is that, for predetermined intervals on the horizontal axis, , for example, when the drawing setting is made to cause large fluctuations in the injection speed of the vertical axis, the fluctuations cannot be read well

Embodiment Construction
[0022]
The molding condition waveform drawing and setting method of the present invention is applicable to an injection molding machine in which molten resin is supplied into the plastic injection cylinder in the metering process, and the injection plunger or the injection screw in the injection plastic cylinder is driven by a driving device in the injection molding process. Forward, the molten resin is injected into the mold at a predetermined speed, and the plunger or the screw is further pressurized by the driving device in the pressure holding process to obtain a molded product.
[0023]
However, in the injection molding process, the position of the plunger is detected as a plunger position detection value by, for example, a position sensor, and the injection speed of the plunger is detected as a speed detection value by taking its differential. These detected values are then sent to a control device that controls the drive. The control device is provided with a stor...

A method for setting molding condition waveforms as set points and a polygonal line between them while drawing on a display device the waveforms input from a coordinate input device on the display device. When a drawing mode is selected, steps including a step for sequentially reading and storing coordinate points drawn and input successively by an operator, while updating them; a step in which adirect distance between the latest coordinate point and the last set point in an already set data table is sequentially calculated; a step in which the coordinate point is stored as the next set pointin the data table when the current direct distance reaches a predetermined distance; and a step in which one set line linearly connecting between the adjacent set points is displayed, are repeated until the input operation of the operator is completed. Thus, the molding condition waveform is set as a polygonal line consisting of the plurality of set lines. Further, when an edition mode is selected, the molding condition waveform which is created can be edited.
Description
technical field [0001] The present invention relates to a method for inputting molding conditions of an injection molding machine, and relates to a method for drawing and setting a molding condition waveform by which a coordinate input device draws and sets a molding condition waveform, and a drawing and setting method for a molding condition waveform capable of editing the generated molding condition waveform Setting method. Background technique [0002] Patent Document 1 (Japanese Patent Publication No. 2-176) proposes that when setting the molding conditions of an injection molding machine in the conventional technology, the molding condition waveform is drawn as a continuous position or time function by a coordinate input device such as a light pen or a touch panel. The method of setting. In this coordinate input device, if a light pen is used, the tip of the pen equipped with a photosensitive device is touched to the screen of the display device of the injection mo...
