摘要:
A method for producing components or profiles from at least one solidifiable plastic compound in an injection moulding facility, said method comprising stationary mould components and mould components which are movable with respect thereto. The method includes injection of solidifiable plastic compound into a channel formed in the movable mould components and, from there, via connections either in portions into one or more mould cavities. The channel is enclosed by at least one stationary, temperature-controlled mould component. A continuous channel compound strand is formed with attachment compound strands, which is transported away from the injection point with increasing cooling and solidification and increasing length, together with the filled mould cavities and mould cavity portions. The channel compound strand, together with the connection mass strands, after its solidification and after opening the mould cavity or the mould cavities is separated from the component(s), and the component or the components is/are ejected.

The invention relates to an injection molding installation with a fixed and a moveable machine clamping plate, and at least one injection unit as well as an injection-molding device which is located between the machine clamping plates for producing profiled parts, elongated at least in sections, by means of closure-side components which are assigned to the one machine clamping plate, and nozzle-side components which are assigned to the other machine clamping plate, as well as a slide module which is located between these components and which has a slide which is arranged in a moveable manner on a closure-side or nozzle-side component, wherein said slide contributes to form an original mould cavity, and a drive module for controlling the movement of the moveable part(s) of the slide module, wherein the part is produced in the intended dimension and shape inside and outside the mold via the movement of the slide. An at least partial functional integration of at least the closure-side components, and/or the drive module, and or the slide module in one or more components in the installation is intended.

A modular aircraft window includes an outer pane and an inner pane each inserted in a substantially rectangular frame. A foldable shade is disposed on one of the frames and has a freely movable end that is coupled with an operating unit for opening and closing the shade. The assembly further includes at least one shade raising and lowering mechanism in one or both of the longitudinal parts of the frame and a drive mechanism mounted in the lower transverse part of the frame. The drive mechanism includes a threaded spindle which, in order to provide for a particularly stable and long-lasting construction of the drive mechanism, is movable solely translationally and is coupled with a transmission mechanism operating the at least one raising and lowering mechanism.

摘要:
A method for the production of elongated profiles or ledges (21) out of solidifying compounds in a mold with at least one lower part and at least one upper part, the molding compound (20) being continuously injected into the mold cavity (4), with the injected molding compound (20) being transported away from the gating point(s) and out of the mold under steady extension of the mold cavity (4) and under steady elongation of the forming profile or ledge (21) by relative movement of mold components and wherein molding compound (20) is injected until the profile or ledge (21) reaches its designated length.In order to manufacture particularly high class profiles and ledges, at the beginning of the injection process the molding compound (20) fills up an end section (4a) of the cavity (4) of the profile or ledge (21) to be formed, said cavity being closed in direction of the exit of the profile, beyond the gating point (3), wherein beyond the gating point (3) due to the process pressure the front section of the molding compound (20) during the relative movement of the mold components remains in position as free front section (20a) of the molding compound (20) with reference to the upper mold part, wherein the mold cavity (4) is filled up while molding compound (20) is transported away from the gating point (3) and out of the mold.
摘要:
A method and an injection mold for the production of profiled and at least partially elongated components out of liquid or viscous solidifying molding compounds, by said injection mold, the molding compound being injected into the mold cavity and transported away under steady extension of the mold cavity and under steady elongation of the component to be formed after the initial filling of the mold cavity. The molding compound transported away is transported out of the mold while molding compound is continuously being injected until the forming component reaches its final length. The mold has at least one mold insert whose surface is part of the peripheral surface of the mold cavity and which is supported in the mold in a movable way in longitudinal direction of the component to be formed so that the mold cavity forming the component can be expanded to the desired size and shape of the component inside and outside of the mold by a movement of the mold insert. Thus the invention makes it possible to produce components that have complex contours, are elongated, at least partially, and have a finite size in a high quality at a low expenditure.

A front jaw having a device for indicating predetermined release values, which front jaw has a housing and a sleeve which is longitudinally adjustable with respect to the housing against the force of a release spring supported on the housing. The sleeve is fastened to one end of a pull rod, the other end of the pull rod carrying a release plate under which short lever arms of two toggle levers grip. The housing has an essentially rectangular recess therein and a window in this recess, with the window enabling the reading of release values indicated by a pointer. The device indicates an exact release value even when the sleeve experiences a change in position relative to the housing during a stepping in with a ski shoe. The sleeve includes an upper surface facing the scale which includes an arrangement for slidably engaging the pointer which is associated with both an engaging device and the scale.

The invention relates to a process for bonding wood base elements to plastic, in particular for production of functional elements, by means of an injection-molding process in which the wood base element is inserted into an injection mold and, at the previously selected sites, plastics melt is injected and irreversibly changes the shape of the wood base element. The process parameters during the injection-molding process are set in such a way that the plastics melt forms depressions (2a, 15a, 32a, 41) acting in the manner of undercuts on the surface of the wood base element (2, 12, 29, 33).

A ski and ski-binding combination. The ski has several holes for receiving therein fastening screws for the selective fastening of ski-binding elements arranged in the ski in the binding-installation area. The holes are covered, however, are marked to the outside by markings. The arrangement of holes for the ski-binding elements is adjusted to the length of the ski and chosen such that the ski bindings are suited to receive only a limited number of successive ski-boot sizes.

A method for producing components or profiles from at least one solidifiable plastic mass in an injection moulding facility, said method comprising stationary mould components and mould components which are movable with respect thereto. The method includes injection of solidifiable plastic mass into a runner formed in the movable mould components and, from there, via connections either in portions into one or more mould cavities. The runner is enclosed by at least one stationary, temperature-controlled mould component. A continuous runner mass strand is formed with attachment mass strands, which is transported away from the casting site with increasing cooling and solidification and increasing length, together with the filled mould cavities and mould cavity portions. The runner mass strand, together with the connection mass strands, after its solidification and after opening the mould cavity or the mould cavities is separated from the component(s), and the component or the components is/are ejected.
