摘要： An apparatus for injecting a molten plastic material into a mold is described. The apparatus includes a heated manifold (manifold) with channels to distribute molten material inside it, and a heated injector, to inject molten material to the mold cavity, equipped with a translatable shutter to regulate the flow of the injected molten material.
An actuator is attached to the manifold to receive molten material from it to send to the injector and move the shutter. The actuator includes a piston connected to the plug, and a first conduit to bring a pressurized fluid from the outside to the piston. A plate includes a second internal conduit to bring pressurized fluid to the injector, where a gap separates the plate and the actuator.
A connecting member is mounted to cross the gap and carry pressurized fluid from the plate to the actuator.-

摘要： An injection molding apparatus is described. It comprises a press equipped with a screw for generating molten material, and a signal generator for generating a control signal adapted for a plurality of directional valves so that they can regulate the movement of one or more actuators adapted for controlling the movement of one or more shutters which regulate a flow of molten material to the mold.
There is a signal converter connected between the press and the mold for converting the signal emitted by the generator into a signal adapted for activating one or more electric actuators, wherein the signal converter is external to the press and the mold.-

摘要： A software-implemented method is described to compare via a graphical interface, freely crossing data relating to simulation results with finite-element analysis software and/or data concerning injection molding machine parameters obtained following molding tests or performed jobs, wherein the data are contained in an electronic database logically structured in one or more sets, and each set is divided into at least two logical portions (82, 84), one relating to the data relating to the simulation results and one relating to the press parameters (molding tests or works carried out), and each portion comprises a plurality of data collections organized internally in a plurality of fields.
Homologous fields of a first and second collection are displayed orderly through a graphical interface by finding the fields in the database through indices generated by the selections.-

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： An apparatus for injection molding of plastic materials includes a mold having at least one plate, a hot runner distributor of the fluid plastic material, at least one injector and an actuator for controlling the opening and the closing of the injector, supported by the distributor and whose cooling is carried out by thermal exchange contact with the plate. Provided for the cooling of the jack actuator is at least one body made of thermally conductive material at least partly surrounding the actuator in an axially slidable manner and it is maintained in thermal exchange contact with the plate by a magnetic force and/or a fluid thrust and/or an electrical drive force.

摘要： A method for injection molding of plastic materials into a cavity of a mold by means of a molding apparatus including at least one injector having a pin valve displaceable between a fully closed position and a maximum opening position, and vice versa, in a controlled fashion in respect of its position and speed. In the opening displacement from the fully closed position to the maximum opening position, the pin valve is initially moved at a first speed and subsequently at a second speed, where the first speed is the highest opening displacement speed of the pin valve.

摘要： A nozzle terminal for injectors of plastic material injection moulding apparatus, includes a tubular tip defining a flow passage for the injected plastic material and including a radially inner element made of a first abrasion resistant material, an intermediate element made of a second high thermal conductivity material, and a radially outer element made of a third corrosion resistant material. The radially inner, intermediate and radially outer elements are joined to each other in intimate mutual contact, and the radially outer element fully covers the intermediate element thus insulating it from the environment.
