摘要： Integrated in the mixing head of a polyurethane apparatus for producing a mixture stream of chemically reactive plastic components, is a cutting arrangement by which natural fibers or fiber strands of soft-elastic and tough consistency can be drawn from a continuous strand and, after cutting into fiber pieces of given length, can be introduced into the mixture stream. The cutting arrangement includes an inner guide tube which receives a fiber strand, drawn from a continuous fiber strand by two feed rollers, and fed via the guide tube and an outer support tube to rotating knife elements. By subjecting the guide tube to a vacuum and applying a compressed gas stream to the end of the outer support tube, the soft-elastic fiber strand is held straight in a manner which is optimal for the cutting process. The cut fiber pieces are introduced together with the gas stream into the mixture stream of chemically reactive plastic components.

摘要： An injection unit for an injection molding machine includes a plasticizing unit in the form of an extruder, a plunger-type injection device, which can be connected to the injection molding machine by an injection nozzle. The plunger-type injection device defines an injection space. The extruder has a forward portion which is connected to the injection space by a melt through channel in which a shutoff valve is disposed. The extruder is operated continuously and includes one or more plasticizing screws, wherein the extruder is configured in such a way that the backup length can expand backwards into the extruder, when the shutoff valve is closed.

摘要： A screw for a plastics processing machine includes a screw body made of a base material, which is no longer useful as a consequence of wear. A single-ply or multi-ply a buffer layer made of magnetically conductive metallic material is applied onto the crest of the screw body by means of a thermal spraying process, and a wear-reducing coating made of molybdenum or a molybdenum-containing alloy and applied onto the buffer layer by means of a thermal spraying process This provides a simple way of ensuring that the regenerated screw has a long service life and is resistant to heavy loads.

摘要： A closing unit for an injection molding machine includes first and second platens, of which at least one is movable, and an intermediate plate disposed between the first and second platens. A molding tool is disposed between one of the first and second platens and the intermediate plate. In order to allow operation of the closing unit with intermediate plate also as a single-face mold for molding a single-component product, the molding operation between the other one of the first and second platens and the intermediate plate is disabled by a dummy tool or by securely fixing the intermediate plate to the other one of the first and second platens. Removal of an end product from the molding tool is realized by at least one ejector which is arranged in or on the intermediate plate.

摘要： A mold portion of a molding tool for making plastic articles includes a base body defining a cavity surface and having formed therein at least one heating channel, and at least one cooling channel separated from the heating channel and having a cross section which is smaller than a cross section of the heating channel. The cooling channel is positioned hereby closer to the cavity surface than the heat channel and thus is in an area between the heat channel and the cavity surface, thereby defining a cavity-proximal cooling channel and a cavity-distal heat channel. Before the injection process, the cavity surface is heated by the heat channel to a higher temperature than the demolding temperature of the plastic article to be formed. At the end of the injection process, the cavity surface is cooled by the cooling system.

摘要： A calibration device for calibrating extruded continuous profiles, in particular tubes, includes a housing and a plurality of segment bodies which are received in the housing in a substantially in circular manner, with axially neighboring segment bodies partially overlapping in a circumferential direction. Each segment body is made from a single-piece workpiece and has a contoured inner surface, wherein the inner surfaces of the segment bodies jointly define a calibration opening for passage of a tube. An operating device retains the segment bodies in the housing and allow adjustment of each segment body in radial direction.

摘要： A horizontal injection molding machine includes a machine bed defining a longitudinal axis and two mold platens supported on the machine bed for movement in a direction of the longitudinal axis, whereby each of the mold platens carries a half-mold. Further provided is a turning device which carries at least two half-molds for interaction with the half-molds on the mold platens, and includes a base plate, which is fixedly mounted to the machine bed between the mold platens, a turntable, and a bearing unit supporting the turntable on the base plate on one side for rotation about a vertical axis. The half-molds of the turning device are hereby attachable on a base-plate distal side of the turntable. The mold platens are moved by a drive mechanism in relation to the turning device, and tie bars extend between the mold platens and are constructed to resist a clamping force.

摘要： The invention relates to an operating system for an externally operated part of a closing unit, in particular for a mold carrier of a closing unit. During operation, the entire closing unit (12) moves in a predefined first direction (D) and the externally operated part (18) can be moved between at least two positions. The externally operated part (18) includes a guide element in the form of a cam roller (22) which is moveable for reaching at least one of the positions in a predefined second position (A) by at least one operating unit (29) arranged separately to the closing unit (12). The operating unit (29) includes at least one gripper member (48) which grabs the cam roller (22) for moving the part (18) to the predefined second position (A) and moves it in this direction. To minimize wear, the gripper member (48) includes two freely moveable guide rollers (50) arranged in parallel relationship at a particular spacing from one another and having axes in substantial parallel or tangential alignment to the first direction (D). The spacing between both guide rollers (50) corresponds essentially to the diameter of the cam roller (22) or is slightly greater than the diameter of the cam roller (22), and the cam roller (22) is able to move into this spacing for moving the externally to-be-operated part (18) in the predefined second position (A) and subsequently is able to move out of the spacing.
