摘要： A system and method for controlling an actuator which actuates an axially displaceable pin valve of an apparatus for injection molding of plastic materials, where the control system includes an electronic control unit of the actuator which adjusts at least one among position, speed and acceleration of the pin valve, and a position sensor which detects a position of a plunger of the actuator and is operatively connected to the electronic control unit. The position sensor indirectly detects the position of the plunger of the actuator.

摘要： To improve the flow symmetry and the molding quality, it is presented a valve pin bushing for the hot runner of an injection mold, including two input channels, each having a geometric axis and through which the material to be injected can enter through an outlet into, and an output channel, which extends along a longitudinal axis up to an output from which the material can exit the valve pin bushing. The portions of the geometric axes, which extend at the outlet are arranged so that on any imaginary plane passing through the longitudinal axis there lies at most one portion.

摘要： A method is described for operating an actuator (10) adapted for moving by means of a pressurized fluid the shutter (12) of an injection nozzle for molten material into a mould, wherein the shutter (12) moves from a closing position, in which there is no passage of molten material through the nozzle, to an opening position, in which there is passage of molten material through the nozzle, and the shutter (12) comprises a chamber (18), and a piston (14) which is movably mounted in the chamber (18), displaced linearly thanks to the thrust of the fluid and connected to the shutter (12) to move it.
The shutter (12) is moved by inserting or removing the predetermined amount of fluid into/from the chamber (18).

摘要： A device is described for adjusting the linear position of one or more shutters (20) in an injection moulding system. The device comprises a body, comprising a cavity in which there can axially slide a movable element, and an adjustment element for adjustment of the axial position of the body with respect to a plate. The adjustment element is rotatably mounted between the body and the plate and comprises a threaded portion on which a corresponding thread of the body and/or of the plate is engaged.

摘要： A method is described for operating an actuator adapted to move via a pressurized fluid circuit a valve pin of an injection nozzle for molten material within a mold, wherein the valve pin moves from a closing position, where no molten material passes through the nozzle, to an opening position, where molten material passes through the nozzle, and the actuator comprises a chamber and a piston that is movably mounted in the chamber, linearly displaced by the thrust of the fluid and connected to the valve pin to move it.
The valve pin is moved by injecting or extracting a predetermined amount of fluid into/from the chamber.

摘要： 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.
