摘要： When a resin passage of a check ring (4) is opened, resin backflow occurs during time when an injection screw (1) is moved forward, and a reverse rotational force is applied to the screw (1) by resin backflow. On the other hand, when the resin passage is closed, there is no resin backflow and the reverse rotational force applied to the screw (1) is greatly reduced. Consequently, after completion of metering process and before injection process, the screw (1) is moved forward after the screw (1) has been rotated in reverse a predetermined amount to prevent resin backflow. At this time, a maximum value of the reverse rotational force applied to the screw (1) is detected. Until the detected maximum reverse rotational force reaches a reference value or less, the reverse rotation amount is increased sequentially and respective molding cycles are carried out. When the detected maximum reverse rotational force reaches the reference value or less (passage closure), the reverse rotation amount at this time is set as the reverse rotation amount for the reverse rotation process. By means of this operation, an optimal reverse rotation amount can be adjusted automatically.

摘要： When a screw (12) equipped with a check ring (30) is moved forward, torque acting on the screw (12) is detected, and whether the check ring (30) is closed is determined on the basis of the detected torque. The screw (12) is rotated in reverse when the check ring (30) is determined not to be closed, and the reverse rotation of the screw (12) is stopped when the check ring (30) is determined to be closed. The reverse rotation of the screw (12) is thereby controlled so that the screw (12) is rotated in reverse by an optimal amount for reliably closing the check ring (30).

摘要： If a screw (1) is moved forward after a metering step is completed, the screw (1) moves in a state where a check ring (3) on a tip end (2) of the screw (1) 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 (3) 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 (3). 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 (3) 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.

摘要： A sliding ring non-return valve primarily for use with an injection molding machine utilizes a frame having cut therein one or more longitudinal grooves. Material flows around the outer edge of a flange surface, into an inlet area, and through the longitudinal grooves in the frame's outer surface before entering an accumulation volume. A ring, dimensioned to fit slidably around the frame, blocks material flow into the grooves while in an upstream position and allows material to pass through the grooves while in a downstream position. In an alternative embodiment, the non-return valve utilizes a frame that surrounds a central passage accessed by inlets. The outlet passage is located downstream of said inlet and connects the central passage with an accumulation volume. A ring is dimensioned to slidably fit around the frame. A flange surface limits the ring's upstream travel, while grooves in the flange surface throttle, or limit, material flow into the inlet area. In an upstream position, the ring blocks material flow into the inlets and seals against a radial seal surface on the flange. In a downstream position, the ring allows positive material flow from the inlet to the outlet. The material backflow around a downstream restraining cap forces the ring to its upstream position prior to the injection stroke.
