Abstract: Injection molding apparatus with a stationary mold clamping plate and a moveable mold clamping plate as well as shafts fixed to one mold clamping plate and passing through openings in the other mold clamping plate, at least one of which has at least one thread on its free end, whereby at least on this free end of the one shaft a drive nut as well as an additional nut for the transmission of the closing force are arranged.

Abstract: An apparatus for plasticising and injecting plastic material comprising a rotatable screw (3) arranged in a cylinder (2), wherein the screw (3) is displaced axially by the rotation of spindles (5) which are rotatable by a servomotor (7) moved axially with the screw (3), by way of of gears (27, 27′) connected by a toothed belt (17), wherein an intermediate transmission (15) for reducing the rotary speed is arranged between the servomotor (7) and the gears (27, 27′).

Abstract: An injection moulding apparatus with mould mounting plates carrying mould tools and a lubricant pump supplying a plurality of consumers and at least one machine part movable by a hydraulic drive, wherein the energy supply of the hydraulic drive (10) is effected by the lubricant pump (20).

Abstract: An injection unit for injection moulding machines comprising a plasticizing cylinder and a plasticizing screw which is arranged rotatably therein and axially displaceably by a crank drive, wherein there is provided a drive motor (1) which selectively either rotates the plasticizing screw (2) or advances same by means of a crank (5) which is pivotably connected to a thrust rod (4), and wherein there is provided a further drive motor (8) which by way of a crank (10) drives a thrust rod (9) arranged in mirror image relationship in plan view in relation to the first thrust rod (4).

Abstract: An apparatus for injection molding thermoplastic material has mold halves carried by stationary and movable mold mounting plates which are mounted on a frame. A control mechanism actively applies a variable torque to one of the mold mounting plates for compensating for any bending of the frame due to the closing force applied between the mold halves.

Abstract: An injection-moulding machine with a movable and a stationary mould-clamping plate (1, 2), wherein struts (4) are mounted in the stationary mould-clamping plate (1, 2), the struts connecting together the movable and stationary mould-clamping plates (1, 2) during the injection operation. The movable mould-clamping plate (2) is able to travel on rails (9) by way of a bracket-like running shoe (14), and, on opening the mould, is able to be released from the struts (4). Carriages (17) with rollers (18) are provided which are pivotally mounted to the movable mould-clamping plate (2) and which are tiltable about a horizontal axis (19) relative to the mould-clamping plate (2) and relative to the running shoes (14). Each running shoe (14) has a front roller (15) which can be raised from the rails (9) and lateral guide rollers (20) with vertical axes of rotation which roll down smooth guide surfaces (30) of the rails (9) and which are likewise raised from the rails (9) during the injection operation.

Abstract: An arrangement for carrying out a two-stage linear movement with a stationary and a movable constructional unit, comprises a hydraulic cylinder and an hydraulic piston preferably in the form of a plunger. The hydraulic piston has a hollow volume which houses a plunger piston which, in turn, rests on a spindle rotated by a servomotor in the movable construct-ional unit. The plunger piston can be displaced axially in the hydraulic piston and also in the hydraulic cylinder by use of the spindle.

Abstract: In an injection molding machine having a machine frame, a stationary mold mounting plate, a movable mold mounting plate and a support portion on the machine frame, which carries a mold closing mechanism, the support portion and the stationary mold mounting plate are connected exclusively by way of the machine frame. The closing force which occurs during the closing phase and the expansion force which occurs during injection, as between the support portion and the stationary mold mounting plate, are carried only by way of the machine frame. The mold mounting plates are mounted tiltably about a respective horizontal axis while a guide means is provided between the two mold mounting plates or the movable mold mounting plate and the machine frame.
