    Abstract: The force pushing the ejector pin when a molded product is ejected is obtained from the driving torque of the servomotor. A malfunction is detected in the ejection step as follows. First, a reference pattern is obtained in advance, when a molded product is normally removed. As the reference pattern, the relationship between torque of the servomotor and time from the initiation of ejecting the ejector pin or the position of an ejector pin is used. At least one monitoring zone is set based on the pattern and the upper and lower limits of torque of each of the monitoring zones are set. A torque value is monitored in each monitoring zone and when the torque value falls outside the upper and lower limits of any one of the monitoring zones, it is determined that a malfunction occurred and an alarm is raised.

    Abstract: A method for monitoring abnormality of a mold-clamping mechanism of a molding machine and for estimating the amount of abrasion in the toggle mechanism without disassembling a mold-clamping mechanism in the molding machine to allow manual inspection. The timing and content of maintenance to be performed is determined based on measurements of stress at the toggle mechanism, from which the amount of abrasion in the toggle is calculated. This method makes it possible to operate the machine until the time just before a product quality deficiency occurs, thereby allowing maintenance to be performed with a minimum of machine disassembly for manual inspection.

    Abstract: A method of controlling operation of an injection molding system in which at least one injection molding device successively executes an injection molding operation thereof so as to successively produce the molded product, and at least one takeout device successively takes out the molded product from the corresponding injection molding device so as to successively transfer the molded product to a subsequent-step part in which the molded product is further processed, while a monitoring device is arranged for detecting an abnormal operation in the subsequent-step part and generating an abnormal signal upon detection of the abnormal signal, the method comprising the steps of: changing an operation mode of the at least one of takeout device so as to transfer the molded disk to another part which is separate from the subsequent-step part, upon generation of the abnormal signal by the monitoring device; and extending a cycle time of the injection molding operation of the at least one injection molding device upon generation of the abnormal signal by the monitoring device.

    Abstract: In the proposed method of molding toothbrushes, a mold with relatively movable mold parts (14, 16) defining at least one molding cavity (20) corresponding in shape to a toothbrush body is used. One of the mold parts (16) has a brush head defining cavity portion with a plurality of holes (24) for partial penetration into the cavity portion of a like number of fiber tufts. Plasticized molding material is injected under pressure into the cavity (20). Pressure within the cavity is sensed during the injecting step. The injection is stopped when the pressure within the cavity exceeds a predetermined pressure value, thereby avoiding any leakage of molding material through the holes (24).
