摘要： Apparatus for reconfiguring at least three finishing rolls in a plastic sheet fabricating sheetline includes a base, a pair of spaced upright support structures, and pairs of first and second spaced support assemblies. The upright support structures are mounted on the base and support a center one of the rolls in a stationary position therebetween and for totation about a first axis. The first support assemblies support a first outer one of the rolls therebetween for rotation about a second axis and are mounted to the support structures for permitting angularly adjustable movement of the first outer roll relative to the center roll about the first axis to reconfigure the angular position of the first outer roll relative to the center roll. The second support assemblies support a second outer one of the rolls therebetween for rotation about a third axis and are mounted to the support structures for permitting angularly adjustable movement of the second outer roll relative to the center roll about the first axis to reconfigure the angular position of the seocnd outer roll relative to the center roll.

摘要： A plasticating screw having a mixing section comprised of two flow channels separated by barrier flights having axially spaced undercut sections and areas of compression and decompression in each channel. Inhomogeneities in the material being plasticated are distributed in both the forward and back directions by means of pressure driven cross-flows caused when the material encounters a section of a channel having a decreasing depth adjacent an undercut section of the barrier flight.

摘要： A method and apparatus for the injection molding of plastics material wherein the forward portion of the screw is designed such that mixing and shear of the material is minimized. This is advantageous when processing materials having diverse colorations so as to produce a mottled product, and also for processing glass reinforced materials wherein high shear processing would break the fibers thereby resulting in a lower quality product. Low shear processing of the material in the forward portion of the barrel is accomplished by providing a screw having a fully flighted rear portion, but a forward portion which is flightless so that a generally unobstructed, annular flow passage is formed between the cylindrical outer periphery of the flighted portion and the inner wall of the barrel. In a mottling application of the apparatus, materials of diverse coloration are softened by the flighted rear portion of the screw but not yet fully mixed so that distinct color patterns are present. When the material reaches the unflighted portion, it will be forced forwardly by the forward pressure developed as the screw continues to pump material forwardly, but the only shear imparted thereto is the gentle wiping action produced by the inner wall of the barrel and the outer periphery of the unflighted portion of the screw so that the streaked condition of the material remains intact. In the case of glass reinforced materials, the circumferential wiping action produced by the unflighted section of the screw aids in wet-out.

摘要： An injection molding machine which is capable of injecting both thermoplastic compounds and glass loaded thermosetting polyester compounds, wherein the machine is capable of rapid conversion from its thermoplastic configuration to its thermosetting configuration, and vice versa. The machine comprises an elongated charge forming barrel having a rearward thermoplastic feed opening, which is customarily supplied by pelletized thermoplastic material from a vertical feed hopper, and a thermosetting material feed opening extending into the barrel at a position forwardly of the thermoplastics feed opening. When processing thermoplastics materials, a conventional, fully flighted plasticizing screw is installed in the barrel so that the pelletized material is conveyed forwardly from the rear feed opening, and plasticized for subsequent injection. During thermoplastics processing, the thermosetting feed opening is plugged. To convert the machine to process the aforementioned thermosetting materials, the second feed opening is unplugged, and the plasticizing screw is exchanged for a deeper flighted conveying screw having flights extending from the forward end thereof to just behind the unplugged, second opening. A stuffer unit is then attached to the unplugged feed opening and dough-like glass loaded thermosetting material is forced through the second opening into the barrel by means of a reciprocating plunger, or the like. The thermosetting material is conveyed forwardly and mixed slightly as the screw rotates.

摘要： A multichannel wave screw with a slush channel barrier section adapted to provide a consistent mixture of 50% solids and 50% melt to both channels of the double wave metering section. The screw includes a barrier flight having a relatively large initial clearance which allows solids to enter the newly formed slush channel. The barrier flight gradually decreases in clearance to a final barrier flight clearance which allows some dispersed solids to enter the slush channel. At the terminal end of the barrier section, the barrier flight abruptly increases its pitch, thereby abruptly narrowing the solids channel and therefore forcing solid material over the barrier flight and into the slush channel. In this manner, a uniform mixture of solid and melt is provided to the multi-channel wave metering section.

摘要： A method for the die casting of end rings and conductor bars in rotors employing a die casting machine having a compensator mechanism comprising a compensator sleeve and a compensator for reciprocal movement along a first axis. A coaxially movable die plate closes off one end of the compensator sleeve to form a die cavity for casting. A plurality of lamination stacks, each held together by a removable stacking pin, are stored on an inclined loading rack positioned laterally on one side of the compensator mechanism. A few of these stacks roll down inclined planes into the compensator sleeves. The compensator pushes the stacks forward into abutment with the die plate and a charge of molten material is injected into the die cavity. The die plate then moves axially away from the compensator and a retriever moves perpendicular to the first axis to an unload position between the compensator sleeve and die plate. The cast rotor is then pushed out of the sleeve and into the retriever, partially by the compensator and completely by injector rods housed within the compensator. The retriever is then retracted to its original position where the stacking pins are pressed out and the rotors are ejected from the retriever onto inclined, V-shaped chutes. A second set of stacks may be loaded and moved into the die cavity simultaneously with pin press-out and rotor ejection.

摘要： An injection molding machine having a dual tonnage traversing cylinder whereby extended stroke mold breakaway force may be exerted by the traversing cylinder unit before it begins its higher speed traversing movement to completely open the mold. The traversing cylinder comprises a normal length piston received within the cylinder barrel and bolted at one end to the moveable platen. The effective working area of the pressure face for this piston during the retraction stroke is such that low force, high speed retraction of the mold section connected to the moveable platen may be achieved. Also disposed within the barrel is a breakaway piston, which may be annular in shape and disposed concentrically with respect to the fast traverse piston and positioned such that it will abut an annular shoulder on the fast traverse piston throughout the retraction stroke of the breakaway piston. The effective working area of the pressure face for the breakaway piston is considerably larger than that of the fast transverse piston so that much greater breakaway force can be exerted on the moveable platen during the early stage of mold separation after the initial, short distance breakaway force is exerted by the main cylinders.

摘要： An injection molding apparatus is disclosed which includes a screw having a multichannel wave screw section. In the wave screw section, a helical passage defined by a radially extending helical screw flight is divided into a pair of flow channels by a radially extending helical barrier. The helical barrier is radially shorter than the helical conveying flight and the effective outer width thereof is axially narrower than the helical conveying flight. Each flow channel is provided with an undulating base surface that defines a plurality of wave cycles. The base surface varies in a radial direction between a valley portion and a crest portion for the wave cycle and a wave cycle is defined as extending between consecutive crest portions. The crest portions of one flow channel are helically displaced from the crest portions of the adjacent flow channel.
