Abstract: The invention relates to a device and method for detecting a force on an injection moulding machine for processing plastic materials. According to said invention, a first element (100) interacting with a mechanical drive and movable at least indirectly thereby in a direction of movement (x) is displaced during said displacement with respect to a second element (200) positioned near the first element (100) or oppositely thereto. A force measuring device (D) is used for determining the force applied on the first (100) and/or second (200) element by the actuation of the injection moulding machine produced by the relative displacement thereof between the first (100) and second (200) elements. A hydraulic chamber whose size is modifiable during the relative displacement associated with a change in pressure of a fluid medium in said hydraulic chamber is firmed between the first (100) and second (200) elements, wherein said change in pressure forms an input signal for adjusting the force or pressure and a pressure-relief valve (30) is used for bypassing the hydraulic medium to a hydraulic medium container (35), when the predetermined or predeterminable presser is exceeded in the hydraulic chamber (10), thereby making it possible to obtain a device and method for detecting a force on an injection moulding machine which makes it possible to determine said force in a favourable alternative manner and simultaneously ensure an overload protection.

Abstract: A device for carrying out a two-stage, linear movement as well as an associated method for displacing a displaceable structural unit relative to a stationary structural unit. A first drive unit drives a shaft, which is in operative connection with a tube, which is connected to the displaceable structural unit. If a predeterminable condition is substantially achieved, a switch is made from the first drive unit to a second drive unit. Because the tube extends through the stationary structural unit and is displaced relative to the stationary structural unit when the first drive unit is actuated, the at least one separating means being jointly displaceable with the second drive unit and coupling in a detachable manner the tube to the second drive unit initially when the condition is achieved and thereby separating the shaft from the flow of force, as soon as the second drive unit is actuated alone, the members, which transfer the rotary movement into a straight movement, can be protected in a two-stage linear movement.

Abstract: An injection-molding unit having an injection motor to activate an electromechanical injection unit for axial movement of the feed screw. An electromechanical rotary motor is provided to turn the feed screw independently of the axial movement. The rotary motor and the injection motor work via a first drive element and a drive element coaxial to the first drive element to make the feed screw move. To transmit the axial movement to the feed screw by linear movement of the injection unit, there is an axial bearing element directly between the first drive element and the other drive element. The axial bearing element is a force-transmission element, but at the same time allows the drive elements to rotate independently of one another and, if necessary, at the same time. This is a simple way of permitting compact coupling of the drive elements for dosing and injection on an injection-molding unit.

Abstract: A mold-clamping unit accommodates an injection mold. The mold clamping unit includes a mold clamping chamber and a clamping mechanism. A crank element with a crank guide defines a guide path curved away from the clamping axis and has a longitudinal extension substantially parallel to the clamping axis. A drive unit moves the extractor along the crank guide and has a driving movement substantially parallel to the clamping axis. A guide unit is connected to the drive unit and the extractor and is guided at two locations on the crank guide. The first end of the drive unit is pivotably attached to the crank element and the second end of the drive unit is attached with hinges to the guide unit. The driving movement moves the guide unit along the guide path for moving the extraction mechanism in and out of the injection mold.

Abstract: A mechanical safety cover interlock for an injection-molding unit has a protective device that covers the mold clamping area. As soon as the protective device is moved from its protecting position, a sensor for an auxiliary circuit emits an electrical signal. As a result of the electrical signal, a control element uses the force of elastic means to steer blocking mechanisms into a blocking position with a blocking section of a locking rod, which hinders the movement of the movable mold carrier when in the blocking position. The position of the control element is monitored with the aid of a position monitoring arrangement.

Abstract: In the case of an injection molding machine for processing plasticizable materials, a structural unit, which includes at least a movable mold carrier, a stationary mold carrier and a closing arrangement of a mold closing unit, is supported on support elements on a machine base. A pivotal axis, about which the structural unit is pivotable, extends transversely relative to a closing axis. A drive unit is provided for pivoting and for displacing the structural unit and is connected pivotally to the machine base and at an articulation point to the structural unit, which articulation point is disposed at a spacing from a pivotal axis. Upon transferring the structural unit from the horizontal position into the vertical position, the drive unit initially pivots the structural unit and then also displaces it.
