DEVICE AND METHOD FOR EVALUATING THE MOULDING STABILITY OF PIECES MOULDED BY AN INJECTION MOLDING MACHINE

The injection molding machine (10) has a screw (12) which reciprocates to inject a molten molding material from the cylinder (11) into a metal mold (14). To evaluate molding stability the injection pressure imparted to the molten molding material by the screw (12) at each screw position is detected by respective means (22, 21), for each molded piece, and the detected injection pressure is then integrated to obtain the work done by the machine, and the molded piece so produced is weighed. A correlation between work done and the weights of molded pieces is statistically obtained. Molding stability is then evaluated from the correlation so obtained. Mould temperature changes e.g. at the commencement of moulding, and material viscosity changes, may be assessed from the relationship between the work done and the injection sequence (Figs 5, and 8). ...

INJECTION MOULDING PROCESS

... 1361911 Digital control of injection moulding process PENNWALT CORP 23 Feb 1972 [1 March 1971] 8371/72 Heading G4H [Also in Division B5] In an injection moulding process in which the injection ram moves over part of its stroke at a constant pressure which is subsequently altered, variation in viscosity of the injected material is compensated by measuring the time required for the ram to advance over a selected part of its stroke, comparing that time with an empirically predetermined time and, during the same injection stroke, changing the time at which the pressure is altered by increments determined by the difference between the measured and predetermined times. Thus if the viscosity falls the constant pressure time is reduced and vice versa so that the delivered shot is substantially the same. An injection moulding apparatus comprises an axially reciprocable screw 16 rotating in a band 12 heated by elements 14. Closure of the mould 32 is effected by pressurizing fluid in lines 46, 48, ...

Injection molding machine and method for determining closure of check ring

The invention relates to an injection machine and method for judging closing of check valve. Torques and resin pressures applied to a screw are detected during the forward movement of the screw and coefficients of correlation between the detected torques and resin pressures are calculated. When the check valve is open, the flight of the screw receives resin pressure, and the screw torque increases proportionally to the resin pressure due to resin backflow, so the coefficients of correlation between the screw torques and the resin pressures are higher than a reference value. When the check valve closes, the flight of the screw no longer receive resin pressure, so the screw torque decreases and the coefficients of correlation become lower than the reference value. The check valve is determined to be closed when the coefficients of correlation become lower than the reference value.
