Publication number: 20250276476Abstract: An injection molding machine includes: a mold clamping device including: a movable platen having a movable mold and a fixed platen having a fixed mold; and a toggle mechanism that moves the movable platen such that a mold device opens and closes, and disposes the movable platen in a mold clamping position; an injection device that injects molding material into cavity space between the movable mold in the mold clamping position and the fixed mold; and a control device that controls the mold clamping and injection devices. A cleaning process is performed, while the movable platen is at a burr-forming position and farther away from the fixed mold than at the mold clamping position, and the injection device injects the molding material into the mold device to mold an article with burrs. A toggle factor at the burr-forming position is a magnification factor of 1 or greater.Type: ApplicationFiled: February 18, 2025Publication date: September 4, 2025Inventors: Koji KAWANO, Shigeru TAKEUCHI, Tatsuya YOKOYAMA

Patent number: 8043549Abstract: An object is to reduce the axial dimension of an injection apparatus (31), facilitate the work of removing and inserting a screw (20), and improve the quality of molded products. The injection apparatus (31) comprises a heating cylinder (17), a screw (20), and a drive apparatus. The screw (20) includes a plasticizing portion which includes a body portion (45a) and a flight (53) projectingly formed on an outer circumferential surface of the body portion (45a). An index ?, which is obtained by dividing a value obtained by adding a screw stroke S and a screw effective length L together by the screw stroke S, satisfies the relation 2.0<?<4.5. Even when the screw (20) is shortened, resin can be melted satisfactorily. Accordingly, the axial dimension of the injection apparatus (31) can be reduced.Type: GrantFiled: August 8, 2008Date of Patent: October 25, 2011Assignees: Sumitomom Heavy Industries, Ltd., Spiral Logic LimitedInventors: Hirotsugu Marumoto, Shigeru Takeuchi, Kohei Washida, Daisuke Goto, Munekatsu Kamiya

Patent number: 8044624Abstract: A load control apparatus outputs a PWM signal to a switching element to control a load. The switching element is connected between a power supply and a grand in series with the load. An abnormal increase detecting unit outputs an abnormal increase detection signal when detecting abnormal increase in applied voltage, which is applied to the load, relative to target voltage. An abnormal decrease detecting unit outputs an abnormal decrease detection signal when detecting abnormal decrease in the applied voltage relative to the target voltage. An operating state monitoring unit outputs a normally operating signal when the load normally operates. A signal combining unit generates a combined signal by combining the abnormal increase detection signal, the abnormal decrease detection signal, and the normally operating signal and outputs the combined signal via a common signal output terminal.Type: GrantFiled: May 15, 2008Date of Patent: October 25, 2011Assignee: DENSO CORPORATIONInventors: Yosuke Matsuo, Shigeru Takeuchi, Taketoshi Sato
