In the present invention, constructed is a highly reliable system that does not allow unforeseen conditions to occur in the remote diagnosis of a clamp device. All combinations of status of a state detection switch mounted on a clamp device are anticipated in advance by a recursive method, and the states are defined with no omissions. A control unit 9 includes: a main body memory 9c that stores the ON/OFF state of a state switch together with the status of an injection molding machine main body, the clamp status and time information; and a main body communication unit 9d which is capable of short-range wireless communication. A message diagnosing a failure is stored in a smartphone 12 for all combinations of the ON/OFF state of the state detection switch for each of the following cases: whether in mold replacement mode or not; and whether a clamp device is in a clamped state or an unclamped state, or in a state other than the forgoing. The history of the ON/OFF state of the state detection switch with respect to the status of the main body and the clamp status is read from the main body memory 9c by wireless communication, and a corresponding message is displayed.

An injection molding system includes a main unit in which a first injection molding machine that injects a first molding material and molds a molded article is disposed and a control unit separated from the main unit and configured to control the first injection molding machine. The control unit is coupled to the main unit via a connection cable having predetermined length.

The present disclosure prevents load from being produced in an injection molding machine. The control device for an injection molding machine according to one embodiment of the present disclosure has a determining part that is configured to determine, based on information detected in accordance with a movement of a measurement motor provided in the injection molding machine, whether or not an operation of removing or attaching a screw that rotates in accordance with the measurement motor has been performed.

An injection molding tool for producing a molded part and a corresponding method are disclosed. The injection mold tool comprises a first tool mold half and a second tool mold half, which together with a first slider and at least one second slider define a free space for the molded part to be produced. A lever which is pretensioned with an elastic element is assigned to an end switch such that a movable and free end of the lever cooperates with the end switch due to a movement of the first slider.

When an injection molding machine performs molding, the mold clamping force on the mold is adjusted on the basis of a mold displacement of the mold or the injection peak pressure and injection foremost position so that the molding is performed without causing flash and by an appropriate mold clamping force with which energy can be reduced. The amount of mold displacement and also the injection peak pressure and the injection foremost position are monitored during automatic operation. If there occurs no mold displacement change exceeding a threshold or if there occurs no injection peak pressure anomaly or injection foremost position anomaly exceeding thresholds, the automatic operation is continued. If the mold displacement change occurs or if the injection peak pressure anomaly and the injection foremost position anomaly occur, the operation of the injection molding machine is stopped.

An injection molding machine includes a resin scattering preventing cover configured to prevent resin scattering from injection nozzle fixed to an end of an injection unit, a lighting unit configured to molding contact portion where the injection nozzle and a mold contact, a fixing unit configured to fix the lighting unit, and an opening/closing portion where the resin scattering prevention cover is configured to open and close; wherein the fixing unit is connected interlocked with opening and closing of the opening/closing portion.

Provided is an injection molding system that makes it possible to maintain convenience while improving safety. The injection molding system comprises an injection molding machine, a peripheral device used in combination with the injection molding machine, and an operation device that is for operating the injection molding machine and the peripheral device and that can be separated from the injection molding machine and the peripheral device and moved. The operation device includes a first operation part for operating the injection molding machine 2, a second operation part for operating the peripheral device, an operation-permitting part that permits operation of the injection molding machine by the first operation part or operation of the peripheral device by the second operation part, and an operation control unit for controlling operation of the injection molding machine and the peripheral device by the first operation part, the second operation part, and the operation-permitting part.

An apparatus and method for actuating a valve stem between an open position and a closed position and for taking one or more valve gated nozzle out of service is disclosed. The hot runner includes a valve gated nozzle having a valve stem, the valve stem coupled to a piston that is held against an actuation plate via pressurized air. When a valve stem becomes stuck in a gate of the hot runner, the actuation plate can continue to move while the piston remains stationary. The valve stem may also be protected from an over force situation such as if the valve stem encounters an obstruction as the actuation plate is moving toward the closed position.
