Abstract:
An injection speed editing/setting method for an injection molding machine, comprising the steps of:(a) displaying coordinates having two rectangular axes on a screen, one of the axes representing the position of a screw, the other representing the injection speed;(b) defining, as a first injection stage, a section from a first screw position to a second screw position, out of an overall movement section of the screw;(c) setting a first injection speed corresponding to said first screw position and a second injection speed corresponding to said second screw position;(d) displaying a point indicative of the relation of the first injection speed to said first screw position and a point indicative of the relation of the second injection speed to said second screw position as a starting point and an end point of the first injection stage, respectively, on said rectangular coordinates;(e) selecting by a user one of a straight line and an arcuate curved line to connect the starting point and the end point of said first injection stage displayed on the screen,when the straight line is selected, displaying a straight line connecting the starting point and end point of said first injection stage,when the arcuate curved line is selected, further inputting, data using a data input device, on a screw position and a corresponding injection speed for giving an intermediate point between said starting point and end point, displaying the inputted intermediate point on said coordinates, and displaying a circular-arc line connecting said starting point, intermediate point and the end point on the coordinates,(f) further defining a second injection stage subsequent to said first injection stage, out of said overall movement section of the screw, as a section from said second screw position to a third screw position;(g) successively executing the processing for the second and following injection stages in the same fashion as those for said steps (c), (d) and (e) until finishing the processing for the last injection stage, and(h) setting and storing the resulting relation of the injection speed to each screw position in the overall screw movement section in a storage device of a control device of the injection molding machine.
