Detailed Description
Hereinafter, a quantitative container 10 according to an embodiment of the present invention will be described with reference to the drawings. Corresponding components in the drawings are denoted by the same reference numerals, and redundant description thereof is omitted.
Hereinafter, a quantitative vessel 10 capable of quantitatively sucking an aluminum melt 71 to be poured into a mold (for example, JIS box mold) from an aluminum melt holding furnace 70 will be described. FIG. 1 is a schematic view of a measuring vessel 10 and an aluminum melt holding furnace 70. In fig. 1, reference numeral 72 denotes alumina.
Fig. 2 is a perspective view of the dosing container 10, and fig. 3 is a sectional view. Fig. 4 is a side view of the dosing container 10 as seen from the direction of arrow a1 in fig. 2.
As shown in fig. 2 to 4, the measuring container 10 includes a container body 20, a cylindrical portion 30 provided in the container body 20, a filter 40 (see fig. 3) attached to the container body 20, and a grip portion 50 (see fig. 4 and omitted in fig. 2) attached to the container body 20.
As shown in fig. 3, the container body 20 includes a cylindrical body portion 21 and a bottom surface portion 22 that closes one side opening of the body portion 21.
The body portion 21 is, for example, a cylindrical body portion. The body portion 21 is not limited to this, and may be another tubular body portion such as a rectangular tubular body portion. The body portion 21 has an inlet 21a for molten aluminum. The injection port 21a is provided at the upper end of the body 21, for example.
The bottom surface portion 22 is formed with a through hole 22a (see fig. 3) through which the aluminum melt passes. The through hole 22a is, for example, a circular through hole formed in the substantially center of the bottom surface portion 22. The through hole 22a is not limited to this, and may be a through hole of another shape such as a rectangular through hole. The through hole 22a may be formed in a region other than the center of the bottom surface 22.
The cylindrical portion 30 is a pipe through which the aluminum melt passes, and extends in a cylindrical shape from the periphery of the through hole 22a in the container body 20, for example, to form a space S (see fig. 3) for holding the aluminum melt between the body portion 21 and the bottom surface portion 22. The cylindrical portion 30 is, for example, a cylindrical portion. The cylindrical portion 30 may be a cylindrical portion having another shape such as a rectangular cylindrical portion.
The container main body 20 and the cylindrical portion 30 are made of a material having a higher melting point than aluminum, for example, a Steel Structure (SS) material.
The container body 20 and the cylindrical portion 30 may be a single piece (for example, a single piece made by cutting a cylindrically shaped blank) or may be a combined piece (for example, a combined piece made by fixing the container body 20 and the cylindrical portion 30 separately from each other by a known means (for example, welding)).
In order to quantify the amount of the aluminum melt in the space S, the cylindrical portion 30 has an opening 31 having a lower end at a position P1 (see fig. 3 and 4) at a predetermined height H from the bottom surface portion 22. The predetermined height H is a height that is considered to allow the molten aluminum in the injection space S to be a fixed amount (amount of the injection mold).
As shown in fig. 4, the opening 31 is, for example, a groove (hereinafter, referred to as a groove 31) extending from the upper end of the cylindrical portion 30 to a position P1 of a predetermined height H. The groove 31 may be tapered from the upper end of the cylindrical portion 30 toward a position P1 having a predetermined height H. The angle θ (see fig. 4) of the taper is, for example, 3 degrees. By using, as the groove portion 31, a groove portion tapered from the upper end portion of the cylindrical portion 30 toward the position P1 of the predetermined height H, the melt overflow preventing cap 60 can be easily attached to the cylindrical portion 30.
As shown in fig. 3, the groove portion 31 is provided on the opposite side of the cylindrical portion 30 from the injection port 21a, and is located above a line of symmetry L connecting the injection port 21a and a symmetrical position P2 of the bottom surface portion 22 located on the opposite side of the injection port 21a with respect to the cylindrical portion 30.
The filter 40 is a filter for filtering the aluminum melt 71 held in the aluminum melt holding furnace 70 (specifically, alumina 72 (see fig. 1) on the surface of the aluminum melt 71), and is, for example, a mesh filter (for example, a plain mesh 14 mesh 0.8mm in wire diameter). The filter 40 is made of a material having a higher melting point than aluminum.
As shown in fig. 3, for example, the filter 40 is attached to the bottom surface 22 of the container body 20 by welding the filter 40 to the bottom surface 22 in a state of covering the through hole 22a formed in the bottom surface 22.
As shown in fig. 4, the grip portion 50 is a portion that an operator grips, and is, for example, a long metal rod (handle). The grip portion 50 is attached to the container body 20 by welding a tip end portion thereof to the container body 20.
Next, the melt overflow preventing lid 60 will be described.
Fig. 5 is a sectional view of the measuring vessel 10 in a state where the melt overflow preventing cap 60 is attached.
As shown in fig. 2 and 5, the melt overflow preventing cap 60 includes a cap main body 61, a closing portion 62, and a holding portion 63.
The melt overflow preventing lid 60 is made of a material having a higher melting point than aluminum, for example, a SS (Steel Structure) material.
The cap body 61, the closure portion 62, and the grip portion 63 may be a single piece (for example, a single piece made by cutting a cylindrical-shaped blank) or an assembly (for example, an assembly made by fixing the cap body 61, the closure portion 62, and the grip portion 63 independently of each other by a known means (for example, welding)).
The cap main body 61 is inserted into the inverted conical portion of the cylindrical portion 30 (see fig. 2 and 5). The blocking portion 62 is a portion inserted into the groove portion 31 formed in the cylindrical portion 30, and is provided at a side portion of the cover main body 61.
The melt overflow preventing cap 60 is attached to the measuring vessel 10 (the cylindrical portion 30) in a state where the upper end portion of the cylindrical portion 30 is closed by the cap main body 61 (the conical surface 61a) inserted into the cylindrical portion 30 (see fig. 2 and 5) and the groove portion 31 is closed by the closing portion 62 inserted into the groove portion 31 (see fig. 2 and 5). Thereby, the leakage of the aluminum melt 71 held in the space S from the groove portion 31 during the transportation of the quantitative container 10 to the mold is suppressed.
The grip 63 is a portion to be gripped by an operator and is provided on the upper portion of the cap main body 61.
Next, an example of the operation of quantitatively sucking the aluminum melt 71 from the aluminum melt holding furnace 70 (see fig. 1) using the quantitative vessel 10 having the above-described configuration will be described.
Fig. 6 is a view showing an example of the operation of quantitatively sucking up the aluminum melt 71 from the aluminum melt holding furnace 70 (see fig. 1) using the quantitative vessel 10. In fig. 6, the molten aluminum holding furnace 70 is omitted.
First, the vessel main body 20 (bottom surface portion 22) held by the operator at the grip portion 50 is immersed in the aluminum melt 71 held in the aluminum melt holding furnace 70 (see fig. 6 a). Specifically, the container main body 20 is immersed in the aluminum melt 71 held in the aluminum melt holding furnace 70 until the position P1 at the predetermined height H is located below the surface of the aluminum melt 71 held in the aluminum melt holding furnace 70.
Thereby, the aluminum melt 71 flows in through the through hole 22a formed in the bottom surface portion 22 and the cylindrical portion 30, flows out from the groove portion 31, and is supplied (poured) into the space S (see arrow B1 in fig. 6 a). At this time, since the alumina 72 (see fig. 1) on the surface of the molten aluminum 71 is filtered by the filter 40, the molten aluminum 71 free of impurities is held in the space S. The molten aluminum 71 flowing in through the through hole 22a formed in the bottom surface portion 22 and the cylindrical portion 30 is supplied until the level of the surface of the molten aluminum 71 held in the molten aluminum holding furnace 70 becomes equal (see fig. 6 (b)).
Next, after the container body is poured into the space S until the height of the container body becomes equal to the height of the surface of the molten aluminum 71 held in the molten aluminum holding furnace 70 (after visual confirmation), the operator extracts the container body 20 from the molten aluminum 71 held in the molten aluminum holding furnace 70 (see fig. 6 c).
Thereby, the aluminum melt 71 supplied to the position P1 exceeding the predetermined height H is discharged through the groove 31, the cylindrical portion 30, and the through hole 22a, and returned to the aluminum melt holding furnace 70 (see arrow B2 in fig. 6 c). Thereby, the aluminum melt 71 of uniform weight without impurities is held in the space S. That is, the aluminum melt 71 is supplied (poured) to the position P1 at the predetermined height H, that is, a fixed amount of the aluminum melt 71 is sucked.
In this way, the molten aluminum 71 can be quantitatively sucked from the molten aluminum holding furnace 70 (see fig. 1).
Next, an example of the operation of pouring the aluminum melt sucked as described above into the mold will be described.
Fig. 7 is a diagram showing an example of the operation of pouring the sucked aluminum melt into the mold.
First, the operator mounts the melt overflow preventing lid 60 to the container main body 20 (cylindrical portion 30) holding the aluminum melt 71 sucked as described above (see fig. 7 (a)). Specifically, the operator grasps the grip portion 63, inserts the cap main body 61 into the cylindrical portion 30, and inserts the blocking portion 62 into the groove portion 31.
Thus, the melt overflow preventing cap 60 is attached to the quantitative container 10 (the cylindrical portion 30) in a state where the upper end portion of the cylindrical portion 30 is closed by the cap main body 61 (the conical surface 61a) inserted into the cylindrical portion 30 (see fig. 2 and 7 a) and the groove portion 31 is closed by the closing portion 62 inserted into the groove portion 31 (see fig. 2 and 7 a).
Next, the operator holds the grip portion 50 and conveys the container body 20 to the mold 80. The mold 80 is, for example, a JIS box mold. JIS box molds are used for casting test pieces, for example. At this time, it is preferable that the container body 20 is conveyed in an inclined state so that the aluminum melt 71 held in the space S during conveyance to the mold 80 does not leak from the groove portion 31, for example, as shown in fig. 7 (b). Since the groove 31 is provided on the opposite side of the cylindrical portion 30 from the injection port 21a and above the line of symmetry L connecting the injection port 21a and the symmetrical position P2 of the bottom portion 22 located on the opposite side of the cylindrical portion 30 from the injection port 21a, the surface of the molten aluminum 71 held in the space S is located below the position P1 having the predetermined height H by inclining the quantitative container 10 (see fig. 7 (b)).
Thereby, the leakage of the aluminum melt 71 held in the space S from the groove portion 31 during the transportation of the quantitative container 10 to the mold is suppressed.
Further, since the melt overflow preventing cap 60 is attached to the container main body 20 (the cylindrical portion 30), the leakage of the aluminum melt 71 held in the space S from the groove portion 31 during the conveyance of the quantitative container 10 to the mold 80 is suppressed.
Next, the operator who has carried to the mold 80 tilts the container body 20, and injects the molten aluminum 71 held in the space S into the mold 80 through the injection port 21a (see fig. 7 c). At this time, since the groove portion 31 is provided on the opposite side of the cylindrical portion 30 from the injection port 21a and above the line of symmetry L connecting the injection port 21a and the symmetrical position P2 of the bottom surface portion 22 located on the opposite side of the injection port 21a with respect to the cylindrical portion 30, the aluminum melt 71 held in the space S is suppressed from leaking from the groove portion 31 even if the container body 20 is tilted.
Next, the results of the test evaluation (for example, K-MOLD test method) for the presence or absence of the incorporation of alumina will be described.
FIG. 8 is a table summarizing the results of performing a test evaluation (e.g., K-MOLD test method) for the presence or absence of alumina incorporation.
In fig. 8, the comparative example is an example (pass at A, B) in which a melt was poured into a mold using a measuring vessel 10 (without a filter 40) to cast a test piece and the cast test piece was subjected to a 5-stage evaluation of a to E, and the example is an example (pass at A, B) in which a melt was poured into a mold using a measuring vessel 10 (with a filter 40) to cast a test piece and the cast test piece was subjected to a 5-stage evaluation of a to E.
Referring to fig. 8, in the comparative example, the yield was 14/22-63.6%, while in the example, the yield was 50/50-100%. That is, it is understood that the molten metal is poured into the mold using the measuring vessel 10 (with the filter 40), whereby the alumina is prevented from being mixed into the cast product (for example, a test piece).
FIG. 9 shows the number of times of the weight of the test piece cast by pouring the melt measured by eye into the mold. Fig. 10 shows the number of times of the test piece weight of the test piece cast by injecting (quantitatively) the aluminum melt sucked from the aluminum melt holding furnace 70 using the quantitative vessel 10 into the mold.
Referring to fig. 9 and 10, when the melt to be measured is poured into the mold, the number of test pieces in the usable range is 27.2% (see fig. 9) for 6 times/22 times, whereas when the melt sucked from the aluminum melt holding furnace 70 using the measuring vessel 10 is poured (measured) into the mold, the number of test pieces in the usable range is 100% for 50 times/50 times. That is, it is understood that a casting (e.g., a test piece) can be generally cast within a usable range by injecting the melt into the mold using the measuring vessel 10.
As described above, according to the present embodiment, the molten aluminum can be quantitatively sucked without using a mechanism for rotating the container, a power source, or the like.
This is because the quantitative container 10 is used, and includes: a container body 20 having a cylindrical body portion 21 and a bottom surface portion 22 closing one side opening of the body portion 21; and a cylindrical portion 30 extending in a cylindrical shape from the periphery of the through hole 22a in the container body 20, forming a space S for holding the aluminum melt between the body portion 21 and the bottom surface portion 22, and the cylindrical portion 30 having an opening 31 with a position P1 at a predetermined height H from the bottom surface portion 22 as a lower end.
Further, according to the present embodiment, since a fixed amount of aluminum melt can be sucked every time, a cast product (e.g., a test piece) having a uniform (substantially uniform) weight can be cast every time by pouring the sucked fixed amount of aluminum melt into a mold. That is, it is possible to suppress defective castings, which are castings whose weight is out of the usable range.
Further, according to the present embodiment, a test piece having no (almost no) mixed alumina can be cast. That is, the casting of a cast product (e.g., test piece) mixed with alumina, that is, a defective product, can be suppressed.
This is because the alumina 72 (see fig. 1) on the surface of the aluminum melt 71 is filtered by the filter 40.
As described above, according to the present embodiment, a test piece having a uniform weight (substantially uniform) and no (almost no) mixed alumina can be cast.
Further, according to the present embodiment, even in the case where the quantitative container 10 is tilted (for example, in the case where the quantitative container 10 is tilted during transportation to the mold, in the case where the container is tilted at the time of injection into the mold), the aluminum melt held in the space S is suppressed from leaking from the groove portion 31. This is because the groove portion 31 is provided on the opposite side of the cylindrical portion 30 from the injection port 21a, and is located above a line of symmetry L connecting the injection port 21a and a symmetrical position P2 of the bottom surface portion 22 located on the opposite side of the injection port 21a with respect to the cylindrical portion 30. Further, by attaching the melt overflow preventing cap 60 to the cylindrical portion 30, leakage of the aluminum melt held in the space S from the groove portion 31 is further suppressed.
Further, according to the present embodiment, since the groove portion 31 is tapered from the upper end portion of the cylindrical portion 30 toward the position P1 of the predetermined height H, the melt overflow preventing cap 60 can be easily attached to the cylindrical portion 30.
Next, a modified example will be explained.
In the above embodiment, the example in which the liquid sucked by the measuring container 10 is the molten aluminum has been described, but the present invention is not limited thereto. For example, the liquid sucked by the measuring container 10 may be a molten metal other than aluminum (e.g., tin, copper), or may be a liquid other than a molten metal (e.g., water).
In the above embodiment, the example in which the filter 40 is attached to the bottom surface portion 22 has been described, but the present invention is not limited to this. For example, the filter 40 may be attached to, for example, the cylindrical portion 30 other than the bottom surface portion 22. The filter 40 may be omitted as appropriate.
The numerical values shown in the above embodiments are exemplary, and appropriate numerical values different from these numerical values may of course be used.
The above-described embodiments are merely exemplary in all respects. The present invention is not limited to the description of the above embodiments. The present invention may be embodied in various other forms without departing from its spirit or essential characteristics.
