Abstract
In an injection molding machine utilizing a setting method of the present invention, there is substantially no limitation in the numbers of steps of an injection speed and a holding pressure, and in addition to rectangle, slope, polygonal line and flat, an arc can be designated as a shape mode. Because of using codes to define the shape mode, the setting operation becomes easy. In order to form one injection speed control pattern, a mix of shape modes may be utilized. Also, in the present setting method, a plurality of code data predeterminedly defined are input sequentially in time, thereby setting the injection speed control pattern or pressure holding control pattern. The code defines a kind of function which figures out an injection speed command data or a holding pressure command data corresponding to each stroke position or time.
