Abstract: An injection pressure waveform for use as a target value for injection pressure feedback control is set based on the actual injection pressure waveform detected when a conforming molded article is obtained. Alternatively, the target injection pressure waveform may be set by modifying a previously retained injection pressure waveform or an actual injection pressure waveform. The previously retained injection pressure waveform or actual injection pressure waveform is displayed on a screen of a display device (T1). Two points on the displayed injection pressure waveform are assigned, and the pressure waveform is modified into a line connecting these two points (T3, T6, T8). Further, two points on the injection pressure waveform and one point between these two points are assigned, and the pressure waveform is modified into a circular arc connecting these three points (T4, T7, T8).

Abstract: A method of and an apparatus for measuring and evaluating characteristics of material resin using an injection molding machine. Injections of resin are performed with different resin temperatures TCi and different injection velocities Vj to detect injection pressures Pr at set screw positions. Data of combinations (Pr, V, TC) of an N number of injection pressures, injection velocities and resin temperatures are obtained. An interdependency relation function PVT(t, v(x),x) expressing correlation among the injection pressure, the injection velocity and the resin temperature is obtained as PVT(t, v(x), x)=A(x)e??(x)Tv(x)?(x) according to a least square method using the obtained data, where ?(x) represents a degree of dependency on injection velocity influencing the injection pressure and “log A(x)??(x)T” represents a degree of dependency on resin temperature influencing the injection pressure.

Abstract: A method of and an apparatus for precisely determining a separating force of a molded product from a mold by an ejector in an injection molding machine. A load exerted on an ejector mechanism in operation without a product molded in the mold is constituted by an inner resistance of the ejector mechanism. The inner resistance includes frictional force produced within the ejector mechanism and resilient forces of springs for returning ejector pins to retracted positions thereof. On the other hand, the load exerted on the ejector mechanism in operation with a product molded in the mold is constituted by the inner resistance and the separating force of the molded product from the mold. Thus, a difference between the loads detected in driving the ejector mechanism with and without a molded product at each ejector position precisely represents the separating force of the molded product from the mold.

Abstract: An injection is carried out under a certain molding condition with a nozzle in an injection molding machine left open to sample an injection pressure Pr in every certain cycle for storing. Detected pressure data Pr(0) to Pr(N) for one shot is stored as reference pressure data Pr0(0) to Pr0(N). When defective molding occurs or when a resin lot is changed or the like, the injection is carried out with the nozzle left open under the same molding condition as that used in obtaining the reference pressure data to obtain the detected pressure data Pr(0) to Pr(N). Waveforms of the detected pressure data Pr(0) to Pr(N) and reference pressure data Pr0(0) to Pr0(N) are graphically represented so that variation of the molding condition is observed. It is assumed that if there are any differences, a problem resides in the resin, while if there is no difference but the defective molding occurs, the problem resides in a mold.
