    摘要： A device for mixing at high-pressure two or more reactive liquid components or resins includes a head-body provided with a mixing chamber with inlet and outlet openings for the injecting and recirculating reactive components; a single-piece tubular element, for delivering the mixture; a valve member with longitudinal recirculation slots; the tubular element is removably inserted into a pass-through hole of the head-body, having annular shoulder zone, separated and distant from the transversal hole; fixing elements removably lock the annular shoulder zone at the head-body for holding the tubular element in the aforesaid hole; a clearance gap between the tubular element and the pass-through hole of the head-body is provided such that the forces are exchanged through the annular shoulder zone; sealing and centering elements avoid leakages of polymeric mixture. Deformation-detecting elements detect the deformation conditions which the tubular element is subjected.

    摘要： A method is disclosed for preparing and dispensing a mixture obtained by mixing at least one first chemically reactive component and at least one second chemically reactive component containing a dispersed solid material i.e. a filler, by a high pressure mixing device comprising a head provided with injectors and one or more interception and supply devices defined by respective nozzles for narrowing the passage of the flows and with correlated plug members that are movable axially and settable for controlling said narrowing. The injectors and the interception and supply device transform the pressure energy of the fluids into kinematic energy of the jets that clash in the mixing chamber to mix the components for turbulence induced by the jets, in which a valve member is slidable, in particular a slide-valve, provided with longitudinal slots for recirculating the components to respective storage tanks. The method provides: removing from at least one tank, by pumping arrangement connected to a respective hydraulic delivery line to the head, a dosed quantity of the at least second chemically reactive second component to with filler material is added; preventing, once said quantity is removed, that the second component flows back from the pumping arrangement to the tank; dosing the component with a controlled flowrate B to the delivery line to the mixing head; keeping the slide-valve closed in a recirculating position and preventing the entry of the at least second component to the head and to the respective recirculating slot and pressurizing, by a dosed quantity Vot, the delivery line to subject the at least second polymeric component to a pressure increase along the delivery line until a value is reached that is near that reached by the passage through the nozzle of the respective interception and supply device; subsequently enabling the entry of the second component into the head to make the second component recirculate to the slots of the slide-valve for a period of time that is comparatively very reduced until it is reduced virtually to zero with respect to a recirculating step of the at least first component through the slide-valve, and subsequently opening by retracting the slide-valve to permit mixing by high pressure collision of the first and at least one second components to dispense the resulting mixture through the mixing chamber and the dispensing conduit for pouring the mixture into a cavity or into a shape to make an object by reaction of the aforesaid first and second chemically reactive components. An apparatus for preparing and dispensing the mixture is also disclosed.

    摘要： A system and method to dispense, mix, and inject liquids and force them into a vented investment pattern mold cavity comprises a source of raw materials in fluid communication with an injection unit for metering and delivering the raw materials. A mixing and injection head receives and mixes the metered raw materials. A movable molding cart upon which an investment pattern mold is mounted is disposed adjacent the injection unit and proximate the mixing and injection head. The movable molding cart includes a fill cup that may be engaged by the mixing and injection head. A displaceable gating tray provides fluid communication with the fill cup and a sprue aligned with an investment port on a lower portion of the investment pattern mold. The system also includes a digital computer control by which the injection process may be controlled.

    摘要： A device for mixing at least two fluid to pasty substances has a housing (2) with at least two openings (5, 6) for feeding the substances and with a discharge opening (8), a mixing element (3) which can rotate in the housing (2), which mixing element (3) can be displaced in the direction (17) of its axis (7) in relation to the housing (2) in order to adjust the size of a gap (18) between a conically tapering part (14) of the mixing element (3) and a likewise tapering region (15) of the housing (2) in order to adjust the shear rate in the region of the gap (18). The mixing element (3) has a region (9) in which annular ribs (11) are provided which project from the mixing element (3) and which engage between adjacent annular ribs (12) which project from the inner surface (10) of the housing (2).
