この発明は、例えばアルミニウム合金等の金属溶湯により鋳物製品を製造することに先立って、その金属溶湯の清浄度を検査するための平板状の被検査片を成形することに用いられる被検査片成形用金型に関するものである。   Prior to manufacturing a cast product with a molten metal such as an aluminum alloy, for example, the present invention provides a molded piece to be inspected that is used to form a flat specimen for inspecting the cleanliness of the molten metal. This is related to the metal mold.

従来、この種の被検査片成形用金型としては、例えば特許文献１に開示されるような構成が提案されている。この従来構成においては、互いに接離可能な上型と下型とが装備されている。その上型と下型との間にはキャビティが形成され、そのキャビティ内に金属溶湯が注入されることにより、細長い平板状の被検査片が成形される。そして、被検査片の成形後に、被検査片が破断されて複数に分割される。さらに、各分割片の破断面が肉眼または拡大鏡等により観察されることにより、金属溶湯の清浄度、すなわち金属溶湯に含まれる介在物の有無や量等が検査される。

Japanese Utility Model Publication No. 49-119419

ところが、この従来構成の被検査片成形用金型では、細長い平板状の被検査片を形成するためのキャビティが、例えば幅３６ｍｍ、長さ２４０ｍｍ、高さ６ｍｍ程度であって、狭い開口断面積で奥行きの深い空間となるように形成されている。このため、キャビティの長手方向の一端部側に設けられた注入口から、キャビティ内に金属溶湯を注入する場合、特に、金属溶湯の温度が高くない場合は、その金属溶湯をキャビティ内の奥部まで円滑に充填させることが困難であった。よって、キャビティ内への金属溶湯の充填に時間がかかって、金属溶湯の温度が低下し、適正検査の可能な被検査片を成形することができないという問題があった。   However, in this conventional mold for molding a test piece, a cavity for forming a long, flat plate-like test piece has, for example, a width of 36 mm, a length of 240 mm, and a height of about 6 mm, and a narrow opening cross-sectional area. It is formed to be a deep space. For this reason, when injecting a molten metal into the cavity from an inlet provided on one end side in the longitudinal direction of the cavity, particularly when the temperature of the molten metal is not high, the molten metal is inserted into the back of the cavity. It was difficult to smoothly fill. Therefore, it takes time to fill the molten metal into the cavity, the temperature of the molten metal is lowered, and there is a problem that it is impossible to form an inspected piece that can be inspected properly.

この発明は、このような従来の技術に存在する問題点に着目してなされたものである。その目的は、キャビティ内へ金属溶湯を短時間に円滑に充填することができて、適正検査の可能な被検査片を成形することができる被検査片成形用金型を提供することにある。   The present invention has been made paying attention to such problems existing in the prior art. An object of the present invention is to provide a mold for molding a test piece that can smoothly fill a cavity with a molten metal in a short time and can mold a test piece that can be inspected properly.

上記の目的を達成するために、この発明は、上型と下型とよりなり、その両型間に金属溶湯の清浄度を検査するための細長い平板状の被検査片を成形するキャビティを設けた被検査片成形用金型において、前記下型には、前記キャビティの下部に開口するとともに、そのキャビティの長手方向に沿って延びる凹状の溶湯通路を形成したことを特徴としている。   In order to achieve the above object, the present invention comprises an upper mold and a lower mold, and a cavity for forming an elongated flat plate-like test piece for inspecting the cleanliness of the molten metal is provided between the upper mold and the lower mold. In the inspected piece molding die, the lower mold is formed with a concave molten metal passage that opens in the lower part of the cavity and extends along the longitudinal direction of the cavity.

従って、この発明の被検査片成形用金型において、キャビティ内に金属溶湯を注入すると、その金属溶湯が溶湯通路を通して、キャビティの長手方向の全体にわたって円滑に供給充填される。よって、キャビティが狭い開口断面積で奥行きの深い空間となるように形成されていても、そのキャビティに対して金属溶湯を、その金属溶湯の温度が低い場合であっても、短時間に充填することができる。このため、適正検査の可能な被検査片を成形することができる。   Therefore, in the mold for molding a test piece according to the present invention, when molten metal is poured into the cavity, the molten metal is smoothly supplied and filled through the molten metal passage in the longitudinal direction of the cavity. Therefore, even if the cavity is formed to be a deep space with a narrow opening cross-sectional area, the molten metal is filled in the cavity in a short time even when the temperature of the molten metal is low. be able to. For this reason, the to-be-inspected piece in which an appropriate inspection is possible can be shape | molded.

また、前記の構成において、前記溶湯通路をキャビティの幅方向の中央部に形成するとよい。このように構成した場合には、キャビティの幅方向の中央部に形成された溶湯通路を介して、キャビティ内へ金属溶湯を一層円滑に供給充填することができる。   Moreover, the said structure WHEREIN: It is good to form the said molten metal channel | path in the center part of the width direction of a cavity. When configured in this way, the molten metal can be supplied and filled more smoothly into the cavity via the molten metal passage formed in the central portion of the cavity in the width direction.

さらに、前記の構成において、前記キャビティの内面には、前記被検査片の表面に分割用のノッチを形成するための複数の突条を、キャビティの幅方向に延びるとともに長手方向に間隔をおいて形成するとよい。このように構成した場合には、被検査片の成形後に、その被検査片の表面に手鋸やヤスリ等を用いて複数の分割用のノッチを形成する必要がなく、作業の簡略化を図ることができる。   Further, in the above configuration, a plurality of protrusions for forming a notch for division on the surface of the inspected piece are formed on the inner surface of the cavity, extending in the width direction of the cavity and spaced apart in the longitudinal direction. It is good to form. In such a configuration, it is not necessary to form a plurality of dividing notches using a hand saw, a file, or the like on the surface of the inspected piece after forming the inspected piece, thereby simplifying the work. be able to.

以上のように、この発明によれば、キャビティ内への金属溶湯の充填を短時間に円滑に行うことができて、適正検査の可能な被検査片を成形することができるといえ効果を発揮する。   As described above, according to the present invention, the molten metal can be filled into the cavity smoothly in a short time, and it can be said that an inspected piece capable of proper inspection can be formed. To do.

（第１実施形態）
以下に、この発明の第１実施形態を、図１〜図５に基づいて説明する。
図１〜図３に示すように、この実施形態の被検査片成形用金型１１は、上下方向へ接離可能に組み付けられる上型１２と下型１３とから構成されている。上型１２と下型１３との接合面には、互いに係脱可能な複数の位置決めピン１４及び位置決め孔１５が形成されている。上型１２の上面にはネジ孔１６が形成され、そのネジ孔１６には着脱操作用のハンドル１７が基端のネジ部１７ａにおいて螺合されて、ナット１８により固定されている。 (First embodiment)
Below, 1st Embodiment of this invention is described based on FIGS.
As shown in FIGS. 1 to 3, the test piece molding die 11 of this embodiment includes an upper die 12 and a lower die 13 that are assembled so as to be able to contact and separate in the vertical direction. A plurality of positioning pins 14 and positioning holes 15 that can be engaged and disengaged with each other are formed on the joint surface between the upper mold 12 and the lower mold 13. A screw hole 16 is formed in the upper surface of the upper mold 12, and a handle 17 for attaching / detaching is screwed into the screw hole 16 at a screw portion 17 a at the base end and fixed by a nut 18.

図１〜図４に示すように、前記上型１２と下型１３との接合面間には、図５に示すような細長い平板状の被検査片３１を成形するためのキャビティ１９が水平方向へ延びるように形成されている。このキャビティ１９は、幅Ｌ１が３６ｍｍ、長さＬ２が２４０ｍｍ、高さＬ３が６ｍｍ程度の、狭い開口断面積で奥行きの深い空間となるように形成されている。キャビティ１９の長手方向の一端部側に連通するように、上型１２の一側上面にはキャビティ１９内にアルミニウム合金等の金属溶湯を注入するための注入口２０が形成されている。   As shown in FIG. 1 to FIG. 4, a cavity 19 for forming an elongated flat plate-shaped inspected piece 31 as shown in FIG. 5 is horizontally disposed between the joint surfaces of the upper mold 12 and the lower mold 13. It is formed to extend to. The cavity 19 is formed to be a deep space with a narrow opening cross-sectional area having a width L1 of 36 mm, a length L2 of 240 mm, and a height L3 of about 6 mm. An inlet 20 for injecting a molten metal such as an aluminum alloy into the cavity 19 is formed on the upper surface of one side of the upper mold 12 so as to communicate with one end in the longitudinal direction of the cavity 19.

図１、図２及び図５に示すように、前記キャビティ１９の内部上面には、複数の突条２１がキャビティ１９の幅方向に延びるとともに長手方向に間隔をおいた状態で形成されている。そして、キャビティ１９内への金属溶湯の注入充填により、キャビティ１９内において被検査片３１が成形される際に、これらの突条２１によって被検査片３１の表面に複数の分割用のノッチ３２が形成される。   As shown in FIGS. 1, 2, and 5, a plurality of protrusions 21 are formed on the inner upper surface of the cavity 19 in a state extending in the width direction of the cavity 19 and spaced in the longitudinal direction. When the inspected piece 31 is formed in the cavity 19 by pouring and filling the molten metal into the cavity 19, a plurality of dividing notches 32 are formed on the surface of the inspected piece 31 by these protrusions 21. It is formed.

図１〜図４に示すように、前記下型１３の上型１２に対する接合面上には凹状の溶湯通路２２が、キャビティ１９の幅方向の中央下部に開口するとともに、そのキャビティ１９の長手方向に沿って延びるように形成されている。この溶湯通路２２は、例えば、幅Ｌ４が１０ｍｍ、高さＬ５が２．５ｍｍ程度の、断面ほぼ四角形状となるように形成されている。そして、前記注入口２０からキャビティ１９内に金属溶湯が注入される際に、この溶湯通路２２を通して、金属溶湯がキャビティ１９の長手方向の全体に供給充填される。   As shown in FIG. 1 to FIG. 4, a concave molten metal passage 22 is opened at the lower center of the cavity 19 in the width direction on the joint surface of the lower mold 13 with respect to the upper mold 12, and the longitudinal direction of the cavity 19 Is formed so as to extend along. For example, the molten metal passage 22 is formed to have a substantially square cross section with a width L4 of about 10 mm and a height L5 of about 2.5 mm. When the molten metal is injected into the cavity 19 from the injection port 20, the molten metal is supplied and filled in the entire length of the cavity 19 through the molten metal passage 22.

次に、アルミニウム合金等の金属溶湯により鋳物製品を製造することに先立って、金属溶湯の清浄度を検査するために、この第１実施形態の構成の被検査片成形用金型１１を用いて、被検査片３１を成形する場合の作用について説明する。   Next, in order to inspect the cleanliness of the molten metal prior to manufacturing the cast product with the molten metal such as an aluminum alloy, the test piece molding die 11 having the configuration of the first embodiment is used. The operation when the inspected piece 31 is molded will be described.

さて、被検査片３１の成形に際しては、図１及び図３に示すように、下型１３上に上型１２が組み付けられた状態で、両型１２，１３が水平状態または注入口２０側を上方にした所定角度（例えば、１０〜３０度の範囲内のいずれかの角度）の傾斜状態に設置される。この状態で、所定温度に加熱した金属溶湯が注入口２０からキャビティ１９内に注入されると、その金属溶湯が溶湯通路２２を通して、キャビティ１９の長手方向の全体にわたって円滑に供給充填される。   Now, when the inspected piece 31 is formed, as shown in FIGS. 1 and 3, the upper mold 12 is assembled on the lower mold 13, and both molds 12 and 13 are in the horizontal state or the injection port 20 side. It is installed in an inclined state at a predetermined angle (for example, any angle within a range of 10 to 30 degrees). In this state, when the molten metal heated to a predetermined temperature is injected into the cavity 19 from the injection port 20, the molten metal is smoothly supplied and filled through the molten metal passage 22 over the entire length of the cavity 19.

従って、キャビティ１９が狭い開口断面積で奥行きの深い空間となるように形成されていても、そのキャビティ１９に対して金属溶湯を短時間に充填することができる。よって、金属溶湯の充填作業中に、その金属溶湯の温度が急激に低下することを抑制することができて、適正検査の可能な被検査片３１を成形することができる。   Therefore, even if the cavity 19 is formed so as to be a deep space with a narrow opening cross-sectional area, the molten metal can be filled into the cavity 19 in a short time. Therefore, it is possible to suppress the temperature of the molten metal from rapidly decreasing during the filling operation of the molten metal, and it is possible to form the inspected piece 31 that can be properly inspected.

また、この第１実施形態においては、溶湯通路２２がキャビティ１９の幅方向の中央部に形成されているため、成形される被検査片３１の厚さが幅方向全体にわたって増加することを抑制することができて、被検査片３１を短時間に硬化させることができる。   Moreover, in this 1st Embodiment, since the molten metal channel | path 22 is formed in the center part of the width direction of the cavity 19, it suppresses that the thickness of the to-be-tested piece 31 shape | molded increases over the whole width direction. And the inspected piece 31 can be cured in a short time.

さらに、この第１実施形態においては、キャビティ１９の内面に複数の突条２１が形成されているため、被検査片３１の成形時に、これらの突条２１により、被検査片３１の表面に分割用のノッチ３２が形成される。よって、被検査片３１の硬化後に、その被検査片３１の表面に手鋸やヤスリ等を用いて複数の分割用のノッチを形成する必要がなく、作業の簡略化を図ることができる。   Further, in the first embodiment, since a plurality of protrusions 21 are formed on the inner surface of the cavity 19, the protrusions 21 are divided into the surfaces of the inspected pieces 31 by the protrusions 21 when the inspected pieces 31 are formed. A notch 32 is formed. Therefore, after the test piece 31 is cured, it is not necessary to form a plurality of dividing notches on the surface of the test piece 31 by using a hand saw, a file, or the like, and the operation can be simplified.

そして、被検査片３１の硬化離型後に、被検査片３１をハンマ等により殴打すると、その被検査片３１が各ノッチ３２に沿って破断されて、複数の分割片３１ａに分割される。その後、各分割片３１ａの破断面を肉眼または拡大鏡により観察することにより、鋳物製品の製造に使用する金属溶湯の清浄度、すなわち金属溶湯に含まれる介在物を検査することができる。   Then, after the test piece 31 is cured and released, when the test piece 31 is beaten with a hammer or the like, the test piece 31 is broken along the notches 32 and divided into a plurality of divided pieces 31a. Thereafter, by observing the fracture surface of each divided piece 31a with the naked eye or a magnifying glass, it is possible to inspect the cleanliness of the molten metal used for manufacturing the cast product, that is, the inclusions contained in the molten metal.

従って、この第１実施形態においては、以下の効果がある。
（１） 金属溶湯が溶湯通路２２を通して、キャビティ１９内を流れるため、その金属溶湯が短時間で円滑にキャビティ１９内に供給充填される。従って、金属溶湯の温度が低めであっても、その金属溶湯をキャビティ１９内に隙間なく充填できて、介在物の有無等の判断に供することができる。 Therefore, the first embodiment has the following effects.
(1) Since the molten metal flows in the cavity 19 through the molten metal passage 22, the molten metal is smoothly supplied and filled into the cavity 19 in a short time. Therefore, even if the temperature of the molten metal is low, the molten metal can be filled into the cavity 19 without any gap, and the presence or absence of inclusions can be determined.

（２） 溶湯通路２２がキャビティ１９の幅方向の中央部に狭い幅で形成されているため、成形される被検査片３１の質量が増加することを抑制することができて、被検査片３１を短時間に硬化させることができる。従って、金属溶湯の硬化中に金属結晶が大きく成長することを防止でき、清浄度判別を適切に行うことができる。   (2) Since the molten metal passage 22 is formed with a narrow width at the central portion in the width direction of the cavity 19, it is possible to suppress an increase in the mass of the test piece 31 to be molded. Can be cured in a short time. Therefore, it is possible to prevent the metal crystal from growing greatly during the hardening of the molten metal, and it is possible to appropriately determine the cleanliness.

（３） しかも、清浄度判別を適切に行い得るための構成は溶湯通路２２を形成しただけであるから、部品点数が増えることはなく、構成が簡単である。
（第２実施形態）
この第２実施形態においては、図６に示すように、断面ほぼ三角形状の溶湯通路２２が、キャビティ１９の幅方向の中央下部に開口するように形成されている。そして、注入口２０からキャビティ１９内に金属溶湯が注入される際に、この溶湯通路２２を通して、金属溶湯がキャビティ１９の長手方向に供給充填される。 (3) Moreover, since the configuration for appropriately performing the cleanliness determination is merely the formation of the molten metal passage 22, the number of parts is not increased and the configuration is simple.
(Second Embodiment)
In the second embodiment, as shown in FIG. 6, a molten metal passage 22 having a substantially triangular cross section is formed so as to open at the center lower portion of the cavity 19 in the width direction. When the molten metal is injected into the cavity 19 from the injection port 20, the molten metal is supplied and filled in the longitudinal direction of the cavity 19 through the molten metal passage 22.

（第３実施形態）
この第３実施形態においては、図７に示すように、断面ほぼ円弧凹状の溶湯通路２２が、キャビティ１９の幅方向の中央下部に開口するように形成されている。そして、注入口２０から注入される金属溶湯が、この溶湯通路２２を通してキャビティ１９の長手方向に供給充填される。 (Third embodiment)
In the third embodiment, as shown in FIG. 7, a molten metal passage 22 having a substantially arc-shaped cross section is formed so as to open at the center lower portion of the cavity 19 in the width direction. The molten metal injected from the injection port 20 is supplied and filled in the longitudinal direction of the cavity 19 through the molten metal passage 22.

以上の第２及び第３実施形態においても、第１実施形態と同様な作用及び効果を得ることができる。
