Abstract: When the screw moves forward, resin backflow occurs. The backflow acts on the screw, applying torque to the screw. During forward movement of the screw, screw torque is produced as shown in FIG. 3A if the check ring is not worn, or as shown in FIG. 3B if the check ring is worn, because wear increases the backflow and delays the closure of the check ring. The magnitude of the peak screw torque and the associated time and screw position vary depending on the presence or absence of wear, so wear of the check ring is estimated from variations in these physical quantities. The state of wear of the check ring, screw head, check seat, and other parts inside the barrel can be estimated.

Abstract: A rotational angle of a motor operative to propel forward a screw in an injection molding machine is detected at an encoder. An output from the encoder is employed to obtain an angular velocity ? of the motor.

The estimated melt pressure value ?? is employed to calculate a torque command value TCMD for the motor, which is fed back to the motor. Thus, precise propelling power control unaffected by noises can be executed without the use of a pressure sensor such as a load cell.

The denture forming apparatus can be used irrespective of the type of resin since the speed of the pressing unit can be regulated. Accordingly, it is possible to realize an improvement over the conventional art, which can use only a designated type of resin.

Abstract: If a screw is moved forward after a metering step is completed, the screw moves in a state where a check ring on a tip end of the screw is in open state. Resin flows in a direction opposite to the injection direction. A rotational force is applied to the screw due to the backflow of the resin. If the check ring closes a resin passage, the rotational force acting on the screw is reduced. A peak time of the screw rotational force is detected as closing point in time of the check ring. Physical amounts such as a screw rotational force and a screw position at that timing are detected. Since the closing point in time of the check ring is precisely detected, correction of the injection/hold pressure switching position and the injection speed switching position can be adjusted more precisely. It is possible to precisely determine whether a molded article is non-defective or defective based on the detected physical amount.

Abstract: While a check ring of a screw of an injection molding machine is in open state, an absolute value (|? resin pressure/? rotation amount|) of a variation of a resin pressure per unit variation of the screw reverse rotation becomes greater than a predetermined reference value. However, after the check ring is closed, |? resin pressure/? rotation amount| becomes equal to or less than the reference value. From this, detecting if the |? resin pressure/? rotation amount| during reverse rotation of the screw, it is possible to determine that the check ring is closed or not. As a result, it is possible to obtain a screw reverse rotation amount which is optimal for reliably closing the check ring.
