Description

1305748 IX. Description of the Invention: [Technical Field to Which the Invention Is Ascribed] The present invention relates to an apparatus for a target fluid separation. Non-cows that catch a passage _ [Prior Art] In the injection molding, the 'melted synthetic material, such as 一, 忐 π, ',,, plastic material) passes through (for example, dry at some point) There are many smelters in the _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Mainly in a τ-shaped configuration. The non-Newtonian fluid flows through a circle ^ is subdivided into a plurality of imaginary concentric hollows, under the shape 'due to the fluid-parabolic velocity distribution, and the passage: the shape of the fluid-fluid+ The flow rate of B 4 (10) towel is large. In this case, several imaginary bodies are empty and equal. The shear between two cylindrical layers is the same as non-Newtonian fluid (for example, (thermal) fluid plastic In the case of a knee with a non-circular shape, the viscosity depends on the shear, and the shear is close to the near A. (4) The material H (four) is larger than this, and the distribution is similar to the - (4):: small. The viscosity of the melt on this section means: in the H + parabola. In the - simplified approximation view, this is similar - column:: in the middle of the road In the heart region, the 'relatively viscous flow melt has a peripheral zone: Γ2 is roughly independent of the radial position', and is slower. The body is larger and more liquid due to the cut wheat, and the flow is illustrated by Figure a-1 C. Figure 1 a shows a circular path through which a non-Newtonian fluid 丨09350.doc 1305748 (eg '-plastic solution) flows. Figure lb shows the flow velocity distribution "v"' on the cross section and Figure b shows the distribution of the shear. The area "廿" corresponds more or less to the aforementioned plunger. / If the non-Newtonian fluid flow of the type shown in Figure 1 is turned in the - rectangular (but) branch T1 of the passage and Separated into two separate streams S1 and S2' as shown in Figure 2, the high viscosity portion and the liquid portion of the fluid will be distributed over the cross section of the passage. The distribution on the cross section is shown in Figure 3, wherein Zone HV represents a high viscosity fluid and residual zone LV represents a low viscosity fluid. In the coordinate system depicted in Figures 2 to 5, the coordinates y are located in the plane of the pattern and the coordinates z extend perpendicular to the plane of the pattern. Therefore, the high viscosity HV portion of the non-Newtonian fluid will be substantially concentrated in Figure 2 • The middle section of the Zhongjijin section and the lower part (in the direction of the figure). This is easy to see because the viscous liquid (refined body) supplied from the central area of the passage section i Advancing to the bottom 5 of the tee, and only then deflecting to the left and right sides of the direction of Figure 2 (as indicated by arrow "a" in Figure 2) and flowing into the peripheral region of the path i The fluid will deflect at the very beginning of the path branch (as indicated by arrow "b"). If the path segments 2a & 2b shown in Figure 2 are extremely long, then gradually, the natural distribution will not It is gradually rebuilt. However, in practice, the passage segments are so short that the distributions shown in Figures 3b and 3c will be substantially maintained as far below the one-way deflection. If the fluid flowing in the passage section 2a encounters a tee whose longitudinal axis extends in the 乂 direction, then the distribution shown in Fig. 4 will establish itself in the discharge passage 3 & The view here is in the direction of flow of the mentioned discharge passage. 109350.doc 1305748 In these discharge paths, we see significant unequalities between the viscous and liquid states and the significant asymmetry of these parts relative to the centers of the channels. The tee T3 of Fig. 2 has two discharge passages 4a and 4b extending perpendicular to the plane of the pattern (in the z direction). Referring to Figure 2a, there is shown a top view of the Fig. 2: top view. After the tee is deflected, it results in the separation of the viscous and liquid state portions of the fluid as shown in Figure Μα. In the discharge passage 4b which is drawn upward from the plane of the drawing in Fig. 2, 'the distribution according to the drawing &' is established, and in the passage of the drawing plane in Fig. 2, the knives according to the figure % are established. This view is also defined by the flow of the tee along the discharge passage. ° In injection molding, if the injection nozzle connected to the injection molding tool (10) mold is not equal in quantity distribution from the solution components of different viscosity (for example, 'Fig. 4b and 4e) and/or where the refining body distribution is not The plurality of vias that are rotationally symmetric with the longitudinal axis of the via (e.g., Figures 3vb and 5b) supply the material, which can result in defects in the cast injection molded product. If we assume that the plate is injected by a plurality of nozzles distributed over a board area, the following defects may occur. If the liquid glare portion from the nozzle in the outer region of the plate is greater than the portion of the liquid state (4) from the nozzle in the inner region of the plate, then under the pressure at the moment of entering the melt, 'will force more melt into the The outer area of the plate in the injection tool (injection mold) rather than the intermediate area means that the material per unit area in the outer area of the plate will be supplied with more material per unit area than the inner area. Will include multiple waveform edges. Conversely 'if more liquid melt is forced into the interior of the injection mold 1 () c) 3 50.doc 1305748 region ' then after the melt is cooled, the internal per unit area is compared A large number of marshallates will cause a bulge in the inner region of the plate. The solution of the solution in the channel section of the right supply 5 is asymmetrical, and even if the trouble is reduced, a similar situation still occurs. If each of the plurality of injection nozzles of a heat path manifold system injects a cup, the unequal distribution of the viscous and liquid melt between the nozzles will result in the cup having a thickness of (4). Result n dazzling group

The asymmetric distribution of the fraction will result in the side of the cup containing the liquid state refinement preferentially: thicker than the opposite side of the cup, resulting in a bulging cup, and/or a right viscous glare entering the mold, then Cannot reach the bottom of the mold. SUMMARY OF THE INVENTION - One of the goals of the month is to develop a different viscosity for minimizing or deflecting, to eliminate the asymmetry and/or unequal amount of cloth and/or prevent it from occurring. The shock is set. In order to achieve this goal, the present invention is in the form of a device for separating a first-class passage (1) of a non-Newtonian fluid (a - embodiment. The material is: a material of 50) The path branch (D) intercepts and deflects the fluid flow path by dividing it m & reducing the viscosity. - The partition is positioned in the soil (7) to have a shoulder setting from the supply passage section ("one suitable for the supply partition (1)). By means of the (4)/clothing distribution of different viscous components of the fluid, the separation of the fluid is achieved without the formation of different viscous components in the remote path. Knife and fork (between the venting passages (2a, 2b) I09350.doc 1305748 Hunting for this embodiment of the invention, the supply of the good or substantially butyl-shaped branch branches is provided by the moon-shaped system: when in-melt When the components are not in the x-rotation, the ρ of the different viscosities are symmetrically distributed. Conversely, in the discharge passage section, the grazing-side special passage branches are two. The ratio of the melt components is generally in the present invention. - the first - extravagant point is the gentleman stream. , β supply - deflection plate to separate the material in the second form of the device, in a branch of the supply passage segment, the peak of different viscosity and eight - up τ The shape of the passage is rotationally symmetrical. The distribution of the number of the passages and the knives is symmetrically distributed (4) and the ratios of the different viscosities and masses in the two discharge passages are substantially equal. The eight in the discharge passage section: , , , And the distribution pattern in the supply section of the knife is substantially the same. "The cloth pattern and thus the discharge passages may have a cross section with the # in the supply passage, so that the road can be smaller. Selection system, these emissions pass [real:: two sections, so that the flow rate is not urgent Reducing or not reducing at all. Figures 6a and 6b show an example of a structure of a device type according to one of the present inventions in a conventional manner. In the first one, the partition U of the glare should be installed to separate it from the supply passage section 曰1 /;, where the partition 11 is placed so that the angle of rotation is such that it can be separated from the glare 'In the case where the two partial streams contain an equal number of fluid components of different viscosities, the fluid kinks having different viscosities are not rotationally symmetrically distributed with the longitudinal axis of the passage. I09350.doc 1305748 in the case of It is distributed between the discharge passages which are set to 1" at the angular position of Fig. 6a, and is directly adjacent to the two viscous and liquid flow streams in the same proportion as shown in Fig. 6b. Melt. The partition 11 can be arranged in an adjustable angular position, in the passage knife, so that it has a fixed adjustment or according to the present invention, the embodiment is shown by way of example. Talk. Figure W' from the T-shaped path The bottom 6 of the branch begins at ';&&;~搪孔12' enters the pond hole 12' and presses the spacer plunger 1 into the non-displacement section 22a, 22b as far as it is, the board... Plate plunger ϊ〇 β Here, the diaphragm plunger system (in the case of the month '10,000 is rotated to the desired angular position, as illustrated in Figure 6, b. To prevent the plunger 10 from being pushed out under operating pressure, The screw plug μ is fixed in its axial position by a screw plug 14 by, for example, a hexagonal socket (10) that fits into the bore 12. The plunger is in the vicinity of the partition At the end of the elbow, there is a solid body of a dome-shaped recess 16 which is rigidly fixed in any manner with its side back facing the supply passage section i. The necessary angular position of the partition is defined by the partition column The position of rotation of the plug 10 into the bore 12 is determined. The retention of the angular position is achieved in any conventional manner, such as by a press fit, or by any other additional suitable rotational fixation. Conveniently, after the previously described plunger has been installed in the passage branch, the diameter of the discharge passages in the region of the dome-shaped recess 16 is drilled from the discharge passages 22a and 22b, Thereby formed (on the projection): I09350.doc 10 1305748 Circular flow opening 17. Of course, these flow openings can also be provided prior to installation of the bulkhead plunger. In Fig. 7, for clarity, the spacer 丨丨 is depicted as being in an angular position perpendicular to the plane of the pattern, and the opening 17 formed by the pupil is depicted as being in the plane of the pattern. It will be appreciated that, in effect, such flow openings 17 are at a rotation of 90. The state, and the angular position of the spacer 采取 takes an angular position associated with the plane of the pattern, as shown in Figure 6b, which is suitable for distribution of fluid components of different viscosities within the supply passage 1. In Figure 7, the bottom portion 6 of the passage branch is shown with a stiffener 18. Reinforcement 18 ° is required only in the case of a commercial pass, or a wall of a heat path manifold block in which the flow paths operate - an insufficiently thick material. Figures 8a and 8b show two previously described partitions. A perspective view of an example of a solid partition plunger ίο. Figure 8a shows the plunger 1' in front of the bored dome-shaped recess 16 in which the rear hexagon socket 13 is shown. The figure shows a plunger having a bore which is conveniently fabricated after installation and a flow opening 7 formed. / In a second embodiment of the device according to the invention, the object sought is to separate and deflect a fluid flow having a symmetrical distribution of fluid components according to different viscosities in the path branch so that substantially This distribution is maintained within the discharge path of the branch branch. Right in Fig. 9b 'Assume that the flow system in the supply passage section 21 is distributed according to the map domain', the distribution in the discharge passage sections 22a and 22b will roughly correspond to the graphs % and 3C. However, if one would supply a fluid flow equal to the fluid flow supplied by the pipe 21 from the lower (in the direction of the drawing) and from the lower '...Hai passage branch, 109350.doc 1305748, it is easy to see The viscous fluid component forced into the passages 22a and 22b along the sides in Figure 9b will be offset by the envisaged additional fluid flow towards the center of the passages 2 2 a and 2 2 b. This effect is achieved by the second type of device of the invention having a common path branch. In a second type of apparatus according to the invention, the viscous fluid component flowing in the center of the supply passage section is separated and the: each component is substantially at right angles to the inlet of the discharge passage section At the intersection, the flow direction at the intersection is substantially perpendicular to the longitudinal direction of the discharge passages. = for this purpose 'in the path branch, there is a deflection plate Μ, the shape of the deflection plate 23 is such that the system-blade 24 enters the supply path and will substantially be in the center of the channel segment 2 1 The +8/^ moving viscous fluid component is divided into two sets of knives 'one component continues to flow on the left side of the deflector plate 23 and the other component in the bias: plate flow. The components are deflected such that they intersect each other at right angles at the bottom of the blade (in the direction of the drawing). The web 27 on which the two components of the viscous component impinge on both sides is only used for mechanical attachment of the deflector 23 to the passage branch. For the effect of the present invention, the actual deflector plate 23 preferably does not have an actual embodiment of the entire area of the passage section 2 I 〇 connected to the turn plate 23. The web Μ 3]. 3) The bore of the cylindrical section in the cylindrical section 32 having a large diameter is pushed to the end, and the flap is passed through a position in the bottom of the branch of the passage, shown and sealed. . Any type of fastening of the web 23 within the branch of the passage will be 12.doc 1305748 sufficient, for example, by means of the strut 28 shown in phantom in Figure 9a, although this is for small diameter passages. It may be difficult.

The deflector plate 23 having the web 27 and the cylindrical section 31 can be formed outside the continuous cylindrical body, with a blade 24 at its front end and a constricted neck at its rear end. The necks are opposite and parallel to each other. The notches on both sides of the blade 24 form a web 27. The opposite side 25 of the deflector plate is preferably located on a circular or similar curved surface' which extends from the blade 24 to the web 27 and forms a transition into the surface of the original cylinder 31. Figure 11 shows a deflection plate of the type shown in Figure 11 mounted in a T-shaped branch branch. The reference numbers in Figure 11 correspond to the reference numerals in Figures 9 and 10, and the reference numbers indicate The same objects in their drawings. Other details, advantages and features of the present invention will become apparent from the description and appended claims.
