  • Publication number: 20200238584
    Abstract: The invention relates to a mold closing unit (10) for an injection molding machine for processing plastics and other compounds that can be plasticized, such as ceramic and pulverous compounds. Said mold closing unit comprises at least one machine bed (20), at least one stationary platen (14), and at least one platen (16) that can be moved relative to the stationary platen (14) by means of a drive mechanism (44), wherein the movable platen (16) can be moved on a slide (22) having guide shoes (26) along at least one guide (24) attached to the machine bed (20), and the drive mechanism (44) has at least one gear rack drive (38) driven by at least one drive motor (32).

  • Publication number: 20200050354
    Abstract: The invention relates to a human machine interface (1) for simultaneously and interactively controlling a control function of a machine (3). The human machine interface (1) comprises a control input unit (5) by means of which a control parameter of a control function of the machine (3) can be simultaneously manually operated in accordance with a parameter input (27), a parameter input unit (7) which can be controlled independently from the control input device (5) and which enables a control parameter of the control function to be manually controlled, and a parameter display unit (9) arranged together with the parameter input unit (7) and which enables feedback of the control parameter to be manually controlled.

  • Publication number: 20180370130
    Abstract: A device and a method for producing a three-dimensional object from at least one fluid-phase, fusable material has at least one discharge unit (12) with FIG. 4 at least one outlet opening for the generative discharge of the fusable material for building up the object (50). By means of at least one fibre feeding device (60), at least one fibre element (61) is supplied for embedding 12 the fibre element in the fusable material discharged from the discharge unit (12), wherein the fibre feeding device (60) is movable for the alignment of the fibre element in relation to an advancement in the building of the object. The fact that the fibre feeding device (60) is mounted on the discharge unit (12) and is movable in relation to the discharge unit (12) means that a selective introduction of fibre elements is made available for the production of a three-dimensional object with improved material properties by the generative process.

  • Publication number: 20140197576
    Abstract: The device and the method serve for the production of a three-dimensional object from a solidifiable by a sequential discharge of drops onto an object carrier for the object to be produced, the device including discharge unit with an outlet orifice discharges drops along an axis (s) in a direction to the object carrier, and control means configured to control the motion of the object carrier and the object on the one hand and the outlet orifice on the other hand relative to each other in space, where due to the fact that means are provided for a mutual alignment of the object carrier or the object on the one hand and the outlet orifice on the other hand and that can be controlled by control means, with the axis (s) in a mutually aligned state intersecting a surface of the object carrier or the already produced object, such that a method and a device are provided for the production of a three-dimensional object with geometric overhangs and/or undercuts using solidifiable materials.
