摘要： The invention relates to a device and a method for carrying out a two-stage linear movement, especially for moving a moveable structural unit (11) in relation to a fixed structural unit (10). A first drive unit (12) drives a shaft (13) which is interactively connected to a pipe (15) that is connected to the moveable structural unit (11). When a predeterminable condition is substantially fulfilled, a changeover from the first drive unit (12) to a second drive unit (17) takes place. The pipe (15) penetrates the fixed structural unit (10) and moves in relation to said fixed structural unit when the first drive unit (12) is activated and the at least one separating means (23) can be moved together with the second drive unit (17) and when the predetermined condition is fulfilled, releasably couples the pipe (15) to the second drive unit (17), hereby separating the shaft (13) from the flow of force as soon as the second drive unit is activated alone. As a result, the elements which translate the rotary movement into a straight movement are protected during a two-stage linear movement.

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 tetragonal prism having a rectangular cross section is attached, as a linear motor movable section (8), to a moving plate (6) to which a screw (3) is attached rotatably and also immovably in an axial direction. A magnet (9a-d) is attached to each surface of the movable section (8). A hole section is provided in an outer frame (10). A linear motor coil (13a-d) is provided on the linear motor fixed section (12a-d) so that it may face the magnet (9a-d) on the surface of the movable section (8). A screw shaft is rotated by a motor through a measuring shaft penetrating a center of the movable section (8). By driving the linear motor comprising the magnet (9a-d) and the coil (13a-d) corresponding to each other, the screw (3) is moved and injected in an axial direction. The fixed section (12a-d) is detachable and a gap between the magnet (9a-d) and the coil (13a-d) can be easily adjusted.

摘要： A moulding machine for moulding microparts containing between 0.001 to 3.5 cubic centimetres of plastics shot volume includes a plasticizing portion operatively connected to an injection portion and a mould portion. A valve member is provided to open and close the connection between the plasticizing portion and the injection portion. A linear motor member is associated with the injection portion to permit moulding times of 0.01 seconds at pressures up to about 690 MPa (100,000 psi) during injection of the molten plastics material into the mould portion.
