PURPOSE:To set a pattern of injection speed and pressure selectively as a time wave and to make it possible to control the injection speed and pressure, by carrying out the adjustment of a target value while an operator is looking it wave shape illustrated on a display apparatus. CONSTITUTION:Actual injection speed and pressure are measured by using detectors 10, 11 in each end of the injection cycle and the value 101 or 102 detected by the detector is illustrated on a CRT display apparatus 1. A pattern of the value set by an operator and a pattern of target value expressed as a smooth function of time are at the same time illustrated on the CRT display apparatus 1. While the operator is looking at these waves being illustrated, the adjustment of the set values of the previous injection speed and pressure is carried out by means of a light pen 6 while taking-in account of the mutual relation of the variables based on the experience and the sixth sence having been obtained up to that time. In each end of an injection cycle, the above described adjustment is then repeated to obtain a pattern of injection speed and pressure to be met with the shape of the molding and the characteristics of the resin. |
