Description
【０００１】[0001]
本考案は、ダイカスト法、溶湯鍛造法等の鋳造法又は樹脂の射出成形等の熱間 で使用する金型の水冷装置に関するものである。 The present invention relates to a water-cooling device for a die used in a hot state such as a casting method such as a die casting method and a molten metal forging method, or a resin injection molding.
【０００２】[0002]
従来の熱間金型の水冷装置として、例えば図４に示すように鋳造金型に使用さ れるものが知られている。この入子ピン５０は、固定金型５１に形成した通孔５ ２に嵌挿され、固定金型５１と分割可能な可動金型５３とで区画されるキヤビテ イ５４に先端部が臨んでいる。入子ピン５０には、基端面に開口する凹所５５が 形成され、この凹所５５内に外側水冷管５６と内側水冷管５７とからなる水冷管 組立体を配置してある。６０はシールリングであり、６３は入子ピン５０を固定 金型５１に固定するための支持プレートである。 2. Description of the Related Art As a conventional water cooling device for a hot mold, one used for a casting mold as shown in FIG. 4 is known. The insert pin 50 is fitted into the through hole 52 formed in the fixed mold 51, and the tip end faces the cavity 54 defined by the fixed mold 51 and the movable mold 53 that can be divided. .. A recess 55 is formed at the base end surface of the insert pin 50, and a water cooling pipe assembly including an outer water cooling pipe 56 and an inner water cooling pipe 57 is arranged in the recess 55. Reference numeral 60 is a seal ring, and 63 is a support plate for fixing the insert pin 50 to the fixed mold 51.
【０００３】 しかして、冷却水流入口６１から内側水冷管５７に供給した冷却水が、内側水 冷管５７の先端から流出し、キヤビテイ５４に臨む入子ピン５０の先端部を冷却 した後、外側水冷管５６と内側水冷管５７との間に流入し、冷却水流出口６２か ら外部に流出する。Then, the cooling water supplied from the cooling water inlet 61 to the inner water cooling pipe 57 flows out from the tip of the inner water cooling pipe 57 to cool the tip of the nesting pin 50 facing the cavity 54, and then to the outside. It flows in between the water cooling pipe 56 and the inner water cooling pipe 57, and flows out from the cooling water outlet 62 to the outside.
【０００４】[0004]
しかしながら、このような従来の熱間金型の水冷装置にあつては、入子ピン５ ０の凹所５５内に外側水冷管５６と内側水冷管５７とからなる水冷管組立体を配 置する構造であるため、入子ピン５０の断面積が小さい場合、その水冷管組立体 を内部へ組み込むことが困難になるという技術的課題がある。 However, in such a conventional water cooling device for a hot mold, a water cooling pipe assembly including an outer water cooling pipe 56 and an inner water cooling pipe 57 is arranged in the recess 55 of the insert pin 50. Due to the structure, there is a technical problem that it is difficult to incorporate the water cooling pipe assembly into the inside when the insert pin 50 has a small cross-sectional area.
【０００５】 すなわち、入子ピン５０の先端部の直径Ｄ0 が小さいときには、先端近くにま で凹所５５を形成することができない。これは、溶湯からの加熱及び加圧状態で 使用される入子ピン５０に所要の強度を確保する観点から、先端近くにまで凹所 ５５を形成できないことに起因する。その結果、内側水冷管５７が中間部にまで しか挿入されず、最も冷却が必要となる入子ピン５０の先端部を冷却できず、入 子ピン５０の過熱に伴う曲がり変形などを早期に発生させて、入子ピン５０の寿 命低下を招来する要因となつている。That is, when the diameter D 0 of the tip portion of the insert pin 50 is small, the recess 55 cannot be formed up to near the tip. This is because the recess 55 cannot be formed close to the tip from the viewpoint of ensuring the required strength of the insert pin 50 used in the state of being heated and pressed from the molten metal. As a result, the inner water cooling pipe 57 is inserted only up to the middle portion, the tip of the nesting pin 50, which requires the most cooling, cannot be cooled, and bending deformation due to overheating of the nesting pin 50 occurs at an early stage. As a result, the life of the insert pin 50 is reduced, which is a factor.
【０００６】[0006]
本考案は、このような従来の技術的課題に鑑みてなされたものであり、その構 成は、金型に形成した通孔に嵌挿され、先端部がキヤビテイに臨む入子ピンを有 する熱間金型の水冷装置において、入子ピンに形成した凹所内に、蒸発部をキヤ ビテイ側としてヒートパイプを挿入すると共に、該ヒートパイプの凝縮部に冷却 水を流通させる冷却水流路を設けることを特徴とする熱間金型の水冷装置である 。 The present invention has been made in view of such a conventional technical problem, and has a structure in which the insert pin is inserted into a through hole formed in a mold and has a tip end facing the cavity. In a hot mold water cooling device, a heat pipe is inserted into a recess formed in the insert pin with the evaporation portion as the cavity side, and a cooling water flow path for circulating cooling water is provided in the condensation portion of the heat pipe. It is a water cooling device for hot dies, which is characterized in that
【０００７】 先ず、型締めした両金型間のキヤビテイに、高温の溶融材料を可動マンドレル 等によつて押し込む。一方、冷却水流路に冷却水を供給し、ヒートパイプの凝縮 部を水冷する。 これにより、キヤビテイ内の溶湯等の溶融材料から熱的影響を受けて次第に昇 温する入子ピンの先端部が、ヒートパイプの蒸発部によつて良好に冷却される。First, a high temperature molten material is pushed into a cavity between the two molds that have been clamped by a movable mandrel or the like. On the other hand, cooling water is supplied to the cooling water passage to cool the condensing part of the heat pipe with water. As a result, the tip portion of the insert pin, which is gradually heated by being affected by the molten material such as the molten metal in the cavity, is favorably cooled by the evaporation portion of the heat pipe.
【０００８】 このような入子ピンの先端部の冷却作用は、入子ピンの凹所にヒートパイプを 挿入することによつて良好に得られる。すなわち、比較的小径の入子ピン内に比 較的小径の凹所を形成し、この凹所内に細いヒートパイプを挿入し、入子ピンの 先端部から離れた位置でヒートパイプの凝縮部を水冷できる結果である。Such a cooling action of the tip portion of the insert pin can be satisfactorily obtained by inserting the heat pipe into the recess of the insert pin. In other words, a relatively small diameter recess is formed in a relatively small diameter insert pin, a thin heat pipe is inserted into this recess, and the condensing part of the heat pipe is placed away from the tip of the insert pin. The result is water cooling.
【０００９】 以下、本考案の実施例について図面を参照して説明する。 図１，図２は、本考案をダイカスト法の入子ピンに適用した第１実施例を示す 。図中において符号１，２は分割可能な金型を示し、一方の金型１が可動側に配 置され、他方の金型２が固定側に配置され、両金型１，２間にキヤビテイ３を画 成する。図２に示すように一方の金型１には、湯口１ａが形成されると共にシリ ンダ部１ｂが形成され、シリンダ部１ｂに可動マンドレル５がスライド自在に嵌 挿される。Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show a first embodiment in which the present invention is applied to a die-casting insert pin. In the figure, reference numerals 1 and 2 indicate dividable molds, one mold 1 is arranged on the movable side, the other mold 2 is arranged on the fixed side, and a cavity is provided between the molds 1 and 2. Define 3. As shown in FIG. 2, a gate 1a and a cylinder portion 1b are formed on one of the molds 1, and a movable mandrel 5 is slidably inserted into the cylinder portion 1b.
【００１０】 そして、他方の金型２には、先端部がキヤビテイ３に臨む入子ピン４が装備さ れる。入子ピン４は、図１に示すように先端側から順次に、直径Ｄ0 の小径部４ ａ、中径部４ｂ、大径部４ｃ及び基端の外向きフランジ部４ｄが形成され、大径 部４ｃを他方の金型２の通孔２ａに液密に嵌挿させて取付けられ、外向きフラン ジ部４ｄが他方の金型２と一体の支持プレート１１に固定されている。The other mold 2 is equipped with a nesting pin 4 whose tip faces the cavity 3. As shown in FIG. 1, the insert pin 4 has a small diameter portion 4a having a diameter D 0 , a middle diameter portion 4b, a large diameter portion 4c, and a proximal end outward flange portion 4d, which are formed in this order from the front end side. The diameter portion 4c is liquid-tightly fitted and inserted into the through hole 2a of the other die 2, and the outward flange portion 4d is fixed to the support plate 11 which is integral with the other die 2.
【００１１】 そして、この入子ピン４には、基端面つまり外向きフランジ部４ｄに開口し、 小径部４ａにまで達する凹所８を形成し、この凹所８内にヒートパイプ６を挿入 する。ヒートパイプ６は、一端側の蒸発部６ａと他端側の凝縮部６ｂとを有し、 内部に内蔵した動作液がウイツクの毛細管現象によつて凝縮部６ｂから蒸発部６ ａに向けて移動する。The insert pin 4 is formed with a recess 8 that opens to the base end surface, that is, the outward flange portion 4d and reaches the small diameter portion 4a. The heat pipe 6 is inserted into the recess 8. .. The heat pipe 6 has an evaporating portion 6a on one end side and a condensing portion 6b on the other end side, and the working fluid contained therein moves from the condensing portion 6b to the evaporating portion 6a by the capillary action of the wick. To do.
【００１２】 このようなヒートパイプ６は、入子ピン４の中心軸線方向に延在するように蒸 発部６ａ側から凹所８内に挿入し、凝縮部６ｂ側端部を、栓体を兼ねる支持部材 １２を介して入子ピン４の外向きフランジ部４ｄに液密に固定してある。但し、 ヒートパイプ６の蒸発部６ａは、凹所８の先端部に広く密着させ、熱伝導度を向 上させることが望まれる。 そして、入子ピン４の大径部４ｃには、ヒートパイプ６の凝縮部６ｂに冷却水 を流通させる冷却水流路７を付属させる。冷却水流路７は、一側の冷却水流入路 ７ａ及び他側の冷却水流出路７ｂからなり、凹所８を介して接続している。The heat pipe 6 as described above is inserted into the recess 8 from the evaporating portion 6a side so as to extend in the central axis direction of the insert pin 4, and the end portion on the condensing portion 6b side is provided with a plug body. It is liquid-tightly fixed to the outward flange portion 4d of the insert pin 4 via a double-sided supporting member 12. However, it is desired that the evaporation portion 6a of the heat pipe 6 be widely adhered to the tip portion of the recess 8 to improve the thermal conductivity. Then, the large diameter portion 4c of the insert pin 4 is provided with a cooling water passage 7 for circulating cooling water to the condensing portion 6b of the heat pipe 6. The cooling water flow path 7 is composed of a cooling water inflow path 7a on one side and a cooling water outflow path 7b on the other side, and is connected via a recess 8.
【００１３】 次に、上記実施例の作用について説明する。 両金型１，２を型締めし、かつ、可動マンドレル５を図１上にて右側に帰り作 動させて金型１の湯口１ａを可動マンドレル５から解放した状態で、所定量の溶 湯を湯口１ａからシリンダ部１ｂ内に注入した後、可動マンドレル５を往き作動 させて溶湯をキヤビテイ３に押し込む。その際、可動マンドレル５がシリンダ部 １ｂをスライドする。Next, the operation of the above embodiment will be described. With the molds 1 and 2 clamped and the movable mandrel 5 returned to the right side in FIG. 1 to operate, the gate 1a of the mold 1 was released from the movable mandrel 5, and a predetermined amount of molten metal was melted. After pouring into the cylinder portion 1b from the sprue 1a, the movable mandrel 5 is moved forward to push the molten metal into the cavity 3. At that time, the movable mandrel 5 slides on the cylinder portion 1b.
【００１４】 一方、入子ピン４には、冷却水流入路７ａから冷却水を供給する。冷却水流入 路７ａから供給された冷却水は、凹所８の一部に入り、ヒートパイプ６の凝縮部 ６ｂを水冷し、高温となつて冷却水流出路７ｂから外部に流出する。 しかして、入子ピン４のキヤビテイ３内に突出する先端部は、キヤビテイ３内 の溶湯から熱的影響を受けて過熱状態になる傾向を呈するが、ヒートパイプ６の 作用によつて良好に冷却される。すなわち、入子ピン４の先端部（小径部４ａ又 は中径部４ｂ）の昇温により、ヒートパイプ６の蒸発部６ａから動作液が蒸発し 、凝縮部６ｂに達して冷却されて凝縮液となり、ウイツクに戻される。凝縮部６ ｂは、冷却水流入路７ａから供給される冷却水によつて冷却されるので、凝縮部 ６ｂでの液化が促される。このようにして、入子ピン４の先端部、特に小径部４ ａまで良好に冷却される。On the other hand, the cooling water is supplied to the insertion pin 4 from the cooling water inflow passage 7a. The cooling water supplied from the cooling water inflow passage 7a enters a part of the recess 8, cools the condensing portion 6b of the heat pipe 6 with water, reaches a high temperature, and flows out from the cooling water outflow passage 7b to the outside. The tip of the insert pin 4 protruding into the cavity 3 tends to be overheated due to the thermal influence of the molten metal inside the cavity 3, but the heat pipe 6 cools it well. To be done. That is, the working liquid evaporates from the evaporating portion 6a of the heat pipe 6 due to the temperature rise of the tip portion (small diameter portion 4a or medium diameter portion 4b) of the insert pin 4, reaches the condensing portion 6b, and is cooled to reach the condensing liquid. And is returned to Wick. Since the condensing part 6b is cooled by the cooling water supplied from the cooling water inflow passage 7a, liquefaction in the condensing part 6b is promoted. In this way, the tip portion of the insert pin 4, especially the small diameter portion 4a, is cooled well.
【００１５】 このような作用は、比較的小径の入子ピン４の小径部４ａ内にまで比較的小径 の凹所８を形成し、この凹所８に細いヒートパイプ６を挿入する結果として得ら れる。Such an effect is obtained as a result of forming a recess 8 having a relatively small diameter even in the small diameter portion 4a of the insert pin 4 having a relatively small diameter, and inserting the thin heat pipe 6 into the recess 8. Be released.
【００１６】 図３には、第２実施例を示し、第１実施例と同一部分には同一符号を付してそ れらの説明を省略する。この実施例にあつては、凹所１８は、先端側から順次に 、小径部１８ａ、中径部１８ｂ及び大径部１８ｃに形成され、小径部１８ａは、 入子ピン４の小径部４ａにまで達している。この凹所１８の小径部１８ａ内に比 較的短いヒートパイプ１６が挿入固定される。すなわち、ヒートパイプ１６は、 入子ピン４の中心軸線方向に延在するように蒸発部１６ａから凹所１８の小径部 １８ａにまで挿入し、凝縮部１６ｂを中径部１８ｂに位置させてある。但し、ヒ ートパイプ１６の蒸発部１６ａは、凹所１８の小径部１８ａに広く密着させ、熱 伝導度を向上させることが望まれる。FIG. 3 shows a second embodiment, and the same parts as those of the first embodiment are designated by the same reference numerals and their description is omitted. In this embodiment, the recess 18 is formed in the small-diameter portion 18a, the medium-diameter portion 18b, and the large-diameter portion 18c sequentially from the tip side, and the small-diameter portion 18a is formed in the small-diameter portion 4a of the insert pin 4. Has reached. The relatively short heat pipe 16 is inserted and fixed in the small diameter portion 18a of the recess 18. That is, the heat pipe 16 is inserted from the evaporating portion 16a to the small diameter portion 18a of the recess 18 so as to extend in the central axis direction of the insert pin 4, and the condensing portion 16b is positioned in the middle diameter portion 18b. .. However, it is desirable that the evaporation portion 16a of the heat pipe 16 be widely adhered to the small diameter portion 18a of the recess 18 to improve the thermal conductivity.
【００１７】 そして、入子ピン４の凹所１８内には、外側水冷管１９と内側水冷管２０とか らなる水冷管組立体２１を基端部側から挿入して配置してある。すなわち、内側 水冷管２０は、外側水冷管１９内に遊挿して基端部を外側水冷管１９に液密に固 着し、内側水冷管２０内に冷却水流入口２２ａに連通する冷却水流入路２２を形 成し、内側水冷管２０と凹所１８の中径部１８ｂ及び大径部１８ｃとの間、並び に内側水冷管２０と外側水冷管１９との間に、冷却水流出口２３ａに連通する冷 却水流出路２３を形成している。この冷却水流入路２２及び冷却水流出路２３に よつて、ヒートパイプ１６の凝縮部１６ｂに冷却水を流通させる冷却水流路を形 成している。A water cooling pipe assembly 21 including an outer water cooling pipe 19 and an inner water cooling pipe 20 is arranged in the recess 18 of the insert pin 4 from the base end side. That is, the inner water-cooling pipe 20 is loosely inserted into the outer water-cooling pipe 19 so that the base end is liquid-tightly fixed to the outer water-cooling pipe 19, and the cooling water inflow path communicating with the cooling water inlet 22a is provided in the inner water-cooling pipe 20. 22 is formed to communicate with the cooling water outlet 23a between the inner water cooling pipe 20 and the middle diameter portion 18b and the large diameter portion 18c of the recess 18, and also between the inner water cooling pipe 20 and the outer water cooling pipe 19. A cooling water outflow passage 23 is formed. The cooling water inflow path 22 and the cooling water outflow path 23 form a cooling water flow path for circulating the cooling water in the condensing portion 16b of the heat pipe 16.
【００１８】 このような水冷管組立体２１は、外側水冷管１９をシールリング２４を介在さ せて凹所１８の大径部１８ｃに液密に嵌挿し、外側水冷管１９の先端部から突出 する内側水冷管２０の先端部内に、ヒートパイプ１６の凝縮部１６ｂを遊挿して ある。In such a water cooling pipe assembly 21, the outer water cooling pipe 19 is liquid-tightly inserted into the large diameter portion 18 c of the recess 18 with the seal ring 24 interposed, and protrudes from the tip end portion of the outer water cooling pipe 19. The condensing portion 16b of the heat pipe 16 is loosely inserted in the tip portion of the inner water cooling pipe 20.
【００１９】 上記構成の水冷装置を備える両金型１，２において、型締め後に溶湯をキヤビ テイ３に押し込むことにより、入子ピン４のキヤビテイ３内に突出する先端部が 、キヤビテイ３内の溶湯から熱的影響を受けて過熱状態になる傾向を呈する。In both dies 1 and 2 equipped with the water cooling device having the above-mentioned configuration, by pushing the molten metal into the cavity 3 after the mold is clamped, the tip end portion of the insert pin 4 protruding into the cavity 3 is located inside the cavity 3. It tends to be overheated due to thermal influence from the molten metal.
【００２０】 しかして、冷却水流入口２２ａから内側水冷管２０に供給した冷却水が、冷却 水流入路２２を通つて内側水冷管２０の先端から流出し、キヤビテイ３に臨む入 子ピン４の先端部付近を冷却した後、冷却水流出路２３に流入し、冷却水流出口 ２３ａから外部に流出する。その過程において、内側水冷管２０の先端から流出 する冷却水によつて、ヒートパイプ１６の凝縮部１６ｂが水冷されるので、冷却 水の直接的冷却作用に加えてヒートパイプ１６の蒸発部１６ａによる冷却作用に よつて、入子ピン４の先端部、特に直径Ｄ0 の小径部４ａが良好に水冷される。Then, the cooling water supplied from the cooling water inlet 22 a to the inner water cooling pipe 20 flows out from the tip of the inner water cooling pipe 20 through the cooling water inflow passage 22, and the tip of the inlet pin 4 facing the cavity 3. After cooling the vicinity of the part, it flows into the cooling water outflow passage 23 and flows out to the outside from the cooling water outlet 23a. In the process, since the condensing part 16b of the heat pipe 16 is water-cooled by the cooling water flowing out from the tip of the inner water cooling pipe 20, in addition to the direct cooling action of the cooling water, the evaporating part 16a of the heat pipe 16 is used. Due to the cooling action, the tip portion of the insert pin 4, particularly the small diameter portion 4a having the diameter D 0 , is favorably water-cooled.
【００２１】 ところで、上記の各実施例は、ダイカスト法に使用する入子ピン４に適用する ものとして説明したが、本考案は、溶湯鍛造法等の鋳造法又は樹脂の射出成形法 などの熱間で使用する金型に装備される入子ピンに対して広く適用が可能であり 、また、ここでの入子ピン４は、先端部がキヤビテイ３に臨んで製品の外形を区 画するものであればよい。By the way, although each of the above-described embodiments has been described as being applied to the insert pin 4 used in the die casting method, the present invention is not limited to a casting method such as a molten metal forging method or a resin injection molding method. It can be widely applied to the insert pins installed in the molds used between, and the insert pins 4 here are those whose front end faces the cavity 3 to define the outer shape of the product. If
【００２２】 以上の説明によつて理解されるように、本考案に係る熱間金型の水冷装置によ れば、ダイカスト法、溶湯鍛造法等の鋳造法又は樹脂の射出成形法等の熱間で使 用する金型の入子ピンにおいて、入子ピンに所要の強度を確保することと、入子 ピンの先端部の冷却を図ることとが良好に両立する。その結果、キヤビテイ内の 冷却を促しつつ、入子ピンの過熱に伴う曲がり変形などを抑制して、入子ピンの 耐久性を向上させることができると共に、製品の内部欠陥を減少させることがで きる。As can be understood from the above description, the hot die water cooling apparatus according to the present invention can be used for heat treatment such as die casting method, casting method such as molten metal forging method, or resin injection molding method. For the insert pin of the die used between the two, it is possible to ensure both the required strength of the insert pin and the cooling of the tip of the insert pin. As a result, it is possible to improve the durability of the insert pin by suppressing bending deformation etc. due to overheating of the insert pin while promoting cooling inside the cavity, and it is possible to reduce internal defects of the product.
