  • Publication number: 20250276476
    Abstract: 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.

  • Publication number: 20250114987
    Abstract: An injection molding machine includes a cylinder; an injection member housed within the cylinder; and a molten resin supply device connected to the cylinder and configured to pump a molten resin from a position closer to a proximal end of the injection member than to a distal end of the injection member. In the cylinder, a pumping force applied to the molten resin by the molten resin supply device is used to move the molten resin in front of the injection member, and the molten resin is accumulated on a front side of an internal space of the cylinder. The molten resin is injected from the distal end of the cylinder by moving the injection member forward.

  • Patent number: 8043549
    Abstract: 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.

  • Patent number: 8044624
    Abstract: 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.
