摘要： In a mold closure position detection method, a mold closure position is detected on the basis of a variation in a physical quantity because of closure of a mold. The method comprises detecting an amount of movement of a movable platen, or a crosshead in the case where the mold clamping apparatus is of a toggle type, during closure of the mold; detecting a variation in the physical quantity because of closure of the mold; obtaining a rate of variation (which encompasses an amount of variation) in the physical quantity to a predetermined amount of movement of the movable platen or the crosshead; and detecting, as a mold closure position, a position of the movable platen or the crosshead when the variation rate reaches a preset ratio.

摘要： In a reciprocating (RS) injection unit environment, as shown in FIG. 1, a controller of the injection unit is arranged to continuously rotate the screw during both conventional plasticizing operation and shot injection. In this way the RS unit is more efficient, utilizing less energy and producing greater resin output. The injection unit includes a non-return valve adjacent a nozzle, which non-return valve is either configured to rotate with the screw to reduce wear or presented as a ball check style noon-return valve. In an injection molding environment, the rotating screw includes flights that allow granules of resin to melt and mix in spaces between adjacent flights, but the flights are arranged substantially to inhibit excessive displacement of resin around the flights.

摘要： The invention relates to a drive device, which is used in particular for the locking unit, the injection unit, or the ejector of an injection-moulding machine for plastics and which has a drive element that can be axially displaced by an electromotor and a hydraulic unit that can be displaced in the same direction as the drive element by being entrained by the latter. The hydraulic unit is a power-transmission element comprising two pistons which can be displaced in relation to one another and have working surfaces of different dimensions. Said hydraulic unit is also an intermediate element, which together with the pistons encloses a pressure chamber that is filled with a hydraulic fluid, when the small piston with the smaller working surface is mechanically connected to the drive element, when the entire hydraulic unit is displaced for a control movement and when the intermediate element is locked to prevent it from being displaced in relation to a fixed frame, in order to enable the larger piston with the larger working surface to exert a great force.

摘要： A method for controlling a screw position of a screw in an injection molding machine uses a high-speed injection and high-speed depressurization method to perform the entire injecting process by controlling speed of the screw. The screw is moved forward to a predetermined first position from an injection start position, and when the screw reaches the predetermined first position, the screw is moved backward to a predetermined second position. The speeds of the forward and backward movement of the screw are controlled in accordance with a screw-position/speed characteristic pattern which is measured in advance, and which is derived from the equation Vnull(2nullKnullS)null where V is screw speed, K is screw acceleration, and S is screw position.

摘要： An energy efficient general purpose injection molding employs a hydraulic drive for injection and clamp machine functions and an electric drive for screw recovery. Both drives use AC “squirrel cage” induction motors under vector control. Speed command signals for the vector controls are generated by the machine's controller utilizing state transition and predictive signal techniques to account for motor and motor/pump response latencies. Hydraulic drive efficiency is improved by varying motor speed/pump output to match cycle requirements to retain hydraulic drive advantages for mold clamp and injection functions while improving the electric drive performance for screw recovery.
