  • Patent number: 10025295
    Abstract: A controller of an injection molding machine stores used/unused information in relation to each of the maximum number of controllable servo amplifiers, outputs an interruption request signal requesting power interruption in a lump to apart of or all of these plurality of servo amplifiers, and receives a power interruption confirmation signal confirming that the motor power of the servo amplifiers is interrupted. Further, the controller determines, on the basis of the interruption request signal, the power interruption confirmation signal and the used/unused information, whether or not interruption driving the servo motor is normally operated.

  • Patent number: 9280152
    Abstract: An injection molding machine has a first servo amplifier configured to operate with a first voltage, a second servo amplifier configured to operate with a second voltage, and a transformer which has a primary side terminal and a secondary side terminal and transforms voltages mutually in a predetermined voltage ratio. A main power supply is connected to a primary side terminal or a secondary side terminal of the transformer, depending on whether a voltage of the main power supply supplied to the injection molding machine is equal to the first voltage or the second voltage, respectively. The first or the second servo amplifier is connected to a terminal of the transformer on the side where the main power supply is not connected.

  • Patent number: 9127810
    Abstract: An injection molding machine has a motor power interruption function such that it is determined whether or not the respective contents of preset first and second interruption criterion settings are different from each other. If the contents of the two settings are determined to be different from each other, then a third motor power interrupt signal is output so that at least one of first and second motor power interruption units is cut off in response to the output signal, thereby interrupting power supply to a motor.

  • Publication number: 20120051954
    Abstract: A fuel pump includes a pump part, a motor part, a motor casing, a motor cover, a terminal, and an electric connector part. The terminal is electrically connectable to an external connector for electricity supply. The electric connector part is disposed at an end portion of the motor cover located on the opposite side from a fitted end of the motor cover which is fitted with a housing, and includes a side surface which is slidably in contact with the external connector to determine a fitting position of the electric connector part relative to the external connector, a bottom face from which the terminal rises up, and an opening which is formed on the side surface to communicate between inside and outside of the electric connector part. The bottom face is an inclined surface whose height becomes lower in a direction from generally a center of the motor cover toward the opening.

  • Publication number: 20120038240
    Abstract: A fuel pump includes a pump part, a motor part, two brushes, two pigtails, and an urging member. Each pigtail is made of a linear conductive member and includes one end portion electrically and mechanically connected to its corresponding brush. The urging member includes one end engaged with a motor casing, and the other end pressing and urging each brush against a commutator from its other axial end face. A distance between an inclined surface of the brush and a sliding surface of the commutator in an axial direction of the brush becomes longer toward a rear side of the brush in a rotation direction of the commutator. A side surface of each brush and an inner wall of the motor casing, which defines two brush accommodating chambers, define a clearance therebetween. Each pigtail includes an extension portion extending from its one end portion toward the rear side in the rotation direction of the commutator.

  • Patent number: 7249940
    Abstract: A temperature regulator main body is connected to a cooling hole formed in a temperature regulating part under a hopper through a tube and comprises a tank for a cooling medium, a pump, a radiator, and a fan facing the radiator to send cold air and driven by a motor. By driving of the pump, the cooling medium circulates between the temperature regulating part under the hopper and the temperature regulator main body. A temperature sensor is provided to the temperature regulating part under the hopper. A controller for controlling an injection molding machine cools the circulating cooling medium by the fan and feedback controls the temperature of the temperature regulating part under the hopper when a temperature detected by the temperature sensor is higher than a preset temperature.
