Abstract: An injection molding device includes a housing having a door, an injection molding machine, a detection section, and a control section. The control section controls voltage applied to the mold clamping motor, and performs mold-clamping and mold-opening of the upper mold and the lower mold by either moving the injection unit and the upper mold along the vertical direction or by moving the lower mold along the vertical direction. The mold clamping device further includes a first brake section that, when application of voltage to the mold clamping motor is stopped, regulates movement of the injection unit and the upper mold in the vertical direction or movement of the lower mold in the vertical direction. When the detection section detects that the door is open or detects intrusion of foreign matter, the control section stops application of voltage to the mold clamping motor.

Abstract: The safety device for injection molds comprises: a plate (1) attachable to a fixed part of a mold; a base (4) attachable to a movable part of a mold; wherein the base (4) comprises a safety shaft (10) movable between an unmounted position, wherein said safety shaft (10) is housed in a bore (13) of the plate (1), preventing displacement between the plate (1) and the base (4), and an assembled position, in which said safety shaft (10) is located outside the hole (13) of the plate (1), the displacement of the safety shaft (10) being driven by an actuator (7), allowing displacement between the plate (1) and the base (4). It ensures the connection of the two parts of the mold when the mold is not mounted on the injection molding machine.

Abstract: An injection molding system includes: an injection molding machine; a collaborative robot installed outside or inside the injection molding machine; and a control unit that controls the collaborative robot. Before the injection molding machine is brought into operation, the control unit operates the collaborative robot at least in a space inside the injection molding machine where molds are installed, and transmits an operation disable signal to the injection molding machine when contact between an object and the collaborative robot or a hand attached to an end of the collaborative robot is detected.

Abstract: A system is described comprising an actuator with a piston linearly movable and a needle shutter connected to the piston for regulating the injection flow of molten material from a nozzle into a mold. By a supply circuit pressurized fluid is brought to the piston to move it back and forth. A solenoid valve is connected to the supply circuit and configured so that in resting condition it leaves open a fluid drainage path for bringing the shutter to a closing position.

Abstract: 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.
