<鋳型の製造方法の説明>
図１は、本実施例の鋳型の製造方法の処理の流れを示すフローチャート図である。この図に示すように、「格子状模型造形ステップ」Ｓ０１０１と「下型製造ステップ」Ｓ０１０２と「中型製造ステップ」Ｓ０１０３と「上型製造ステップ」Ｓ０１０４と「注湯空間構成ステップ」Ｓ０１０５とからなる。以下、各ステップについて説明する。
<Description of mold manufacturing method>
FIG. 1 is a flowchart showing the flow of processing of the mold manufacturing method of this embodiment. As shown in this figure, it consists of a “lattice model shaping step” S0101, a “lower mold manufacturing step” S0102, an “middle mold manufacturing step” S0103, an “upper mold manufacturing step” S0104, and a “pouring space configuration step” S0105. . Hereinafter, each step will be described.
「格子状模型造形ステップ」Ｓ０１０１では、充填物を上面開口から縦方向に詰め込み可能に板状仕切りで仕切られる複数の区画を備え、複数の区画の上面開口まで目一杯に詰め込まれた充填物の表面によって所望の曲面を造形することができる格子状模型を利用して、格子状下型模型及び格子状注湯空間模型を製造する。「下型製造ステップ」Ｓ０１０２では、格子状下型模型を平面に配置して造形に必要な区画を充填物で埋めて固め下型とする。「中型製造ステップ」Ｓ０１０３では、下型の上に格子状注湯空間模型を配置して各区画を充填物で埋めて固め中型とする。「上型製造ステップ」Ｓ０１０４では、中型の上に充填物を盛りつけて固め上型を製造する。「注湯空間構成ステップ」Ｓ０１０５では、中型を取り除き下型と上型とを合わせて注湯空間を構成する。 In the “lattice model shaping step” S0101, a plurality of compartments partitioned by plate-like partitions are provided so that the filler can be vertically packed from the upper surface opening, and the filling material packed up to the upper surface opening of the plurality of compartments is packed. A lattice-shaped lower mold model and a lattice-shaped pouring space model are manufactured using a lattice-shaped model that can form a desired curved surface by the surface. In “lower mold manufacturing step” S0102, a lattice-shaped lower mold model is arranged on a plane, and a section necessary for modeling is filled with a filling material to form a lower mold. In the “medium mold manufacturing step” S0103, a lattice-shaped pouring space model is arranged on the lower mold, and each section is filled with a filler to be solidified. In the “upper mold manufacturing step” S0104, a filler is placed on the middle mold to produce a hardened upper mold. In the “pouring space forming step” S0105, the middle mold is removed and the lower mold and the upper mold are combined to form the pouring space.
格子状模型の一例として格子状下型模型について説明する。図２は、格子状下型模型の形状とそれを用いて製造される下型を示した斜視図である。この図からも分かるように、格子状下型模型は複数の板状仕切りを組み合わせることによって形成されるものであり、板状仕切りで仕切られる複数の区画は鋳物砂等の充填物を上面開口から縦方向に詰め込みが可能になっている。複数の板状仕切りは、例えば図３に示すように、切り込みを各々組み合わせることで結合することが可能である。また、複数の区画を仕切る板状仕切りの間隔は一定にする必要はなく、鋳型の曲面の曲率が大きいところは板状仕切りの間隔を狭くし、曲率が小さいところは間隔を広くするといったことも可能である。また、板状仕切りの間隔を１００ｍｍ以下の間隔で配置することによって、所望の曲面を高い精度で再現することが容易になる（以下の実施例でも同様である）。 A lattice-shaped lower mold model will be described as an example of the lattice-shaped model. FIG. 2 is a perspective view showing the shape of a lattice-shaped lower mold model and a lower mold manufactured using the same. As can be seen from this figure, the lattice-shaped lower model is formed by combining a plurality of plate-like partitions, and the plurality of compartments partitioned by the plate-like partitions are filled with casting sand or the like from the upper surface opening. Stuffing in the vertical direction is possible. As shown in FIG. 3, for example, the plurality of plate-like partitions can be combined by combining cuts. In addition, it is not necessary to make the interval between the plate-like partitions that divide the plurality of compartments constant, the interval between the plate-like partitions is narrowed when the curvature of the curved surface of the mold is large, and the interval is widened when the curvature is small. Is possible. Moreover, it becomes easy to reproduce a desired curved surface with high accuracy by arranging the intervals of the plate-like partitions at intervals of 100 mm or less (the same applies to the following examples).
また、板状仕切りの材料としては、段ボール紙などの紙材やベニヤ板などの木材、プラスチック材などの加工しやすい素材を用いることによって、さらに作業効率を向上させることも可能である（以下の実施例でも同様である）。 In addition, work efficiency can be further improved by using easy-to-process materials such as corrugated paper, wood, plastic, etc. The same applies to the example).
板状仕切りを製造する方法としては、ＣＡＤ（Computer aided design）等のプログラムにより加工データを作成し、当該データに基づいて一般的な工作機（段ボール紙やベニヤ板の切断をする工作機等）で作成する方法が考えられる。ＣＡＤ等で得られるデータとしては、各板状仕切りの縦横の長さ、各板状仕切りを組み合わせるための切り込みの位置等が考えられる。これらのデータに基づいて作成された板状仕切りを組み合わせることで目的とする格子状模型を製造することが可能になる。 As a method of manufacturing a plate-shaped partition, machining data is created by a program such as CAD (Computer Aided Design), and a general machine tool (machine tool for cutting corrugated paper or plywood etc.) based on the data is used. A method of creating can be considered. As data obtained by CAD or the like, the length and width of each plate-like partition, the position of a cut for combining each plate-like partition, and the like can be considered. By combining plate-like partitions created based on these data, it is possible to manufacture a target lattice model.
格子状下型模型を平面に配置して造形に必要な区画を鋳物砂等の充填物で埋める際は、基本的に各区画の縁の高さと同じレベルまで充填物を詰め込んで、各区画の表面を形成することが可能である。なお、細部の凹凸形状をならすためにヘラなどの成型用工具を用いることが好ましい。ここで、充填物の表面を整える作業は格子状模型の区画を小さくすればする程容易になる。 When placing the lattice-shaped lower model on a flat surface and filling the sections required for modeling with a filler such as foundry sand, the filler is basically packed to the same level as the edge height of each section. It is possible to form a surface. In addition, it is preferable to use a molding tool such as a spatula in order to smooth out the uneven shape of the details. Here, the work of preparing the surface of the filling becomes easier as the section of the lattice model is made smaller.
また、格子状下型模型に充填物を詰め込んで固める際は、格子状模型の周囲を枠で囲んで型崩れしないようにすることが好ましい。また、板状仕切りとして段ボール紙などの紙材を用いている場合は、蝋などを用いて負荷がかかる部分（充填物の重みによって曲がりやすい端部など）の強度を向上させることが好ましい In addition, when filling the grid-like lower mold model with a filler, it is preferable to surround the grid model with a frame so as not to lose its shape. Further, when a paper material such as corrugated cardboard is used as the plate-like partition, it is preferable to improve the strength of a portion (such as an end portion that is easily bent due to the weight of the filler) using wax or the like.
また、充填物として鋳物砂を用いる場合は、鋳物砂に水ガラスを含ませておき、二酸化炭素を吹き込むことで鋳物砂をさらに硬化させることも可能である。また、フラン樹脂を酸と共に鋳物砂に含ませておき、硬化させる方法なども考えられる。 Moreover, when using foundry sand as a filler, it is possible to further harden the foundry sand by adding water glass to the foundry sand and blowing carbon dioxide. Moreover, the method etc. which are made to contain furan resin with an acid in foundry sand, and to harden | cure etc. are also considered.
図４は下型の上に格子状注湯空間模型を配置し、その後各区画を充填物で埋めて固めた状態を示した図である。ここで、中型における点線は中型の断面形状を表したものである。格子状注湯空間模型の各区画を充填物で埋めて固める工程は、基本的に下型を製造する工程と同じであるが、下型と中型の充填物が混ざりあわないように間に分離剤を塗布することや、ビニール等のシート状のものを挟んでおくことが考えられる。また、下型と中型の充填物に異なる種類のものを用いることも考えられる。 FIG. 4 is a view showing a state in which a lattice-shaped pouring space model is arranged on the lower mold, and then each section is filled with a filler and hardened. Here, the dotted line in the medium mold represents the cross-sectional shape of the medium mold. The process of filling and solidifying each section of the lattice-shaped pouring space model with a filler is basically the same as the process of manufacturing the lower mold, but it is separated so that the lower mold and the middle mold do not mix. It is conceivable to apply an agent or sandwich a sheet-like material such as vinyl. It is also conceivable to use different types of lower and medium fillings.
図５は、中型の上に充填物を盛りつけて固めて上型を製造した状態を示した図である。ここで、上型と中型及び下型を分離する際に、型崩れしないように上型を取り囲む枠を設けておくことが好ましい。また、粘結剤等を用いて上型の充填物を強固に固めておくことも好ましい。また、中型と上型の間に分離剤を塗布することや、間にビニール等のシート状のものを挟んでおくことも可能である。なお、本実施例では上型を格子状模型を用いないで製造する方法を示したが、下型や中型と同様に、格子状上型模型を利用して製造する方法も可能である。 FIG. 5 is a view showing a state in which the upper die is manufactured by placing a filler on the middle die and solidifying it. Here, when separating the upper mold from the middle mold and the lower mold, it is preferable to provide a frame surrounding the upper mold so that the mold does not collapse. It is also preferable to firmly solidify the upper filling using a binder or the like. It is also possible to apply a separating agent between the middle mold and the upper mold, and to sandwich a sheet-like material such as vinyl. In the present embodiment, the method of manufacturing the upper mold without using the lattice-shaped model is shown, but a method of manufacturing using the lattice-shaped upper mold model as well as the lower mold and the middle mold is also possible.
図６は、中型を取り除き下型と上型とを合わせて注湯空間を構成した状態を示した図である。ここで、中型を取り除いて下型と上型を合わせる方法としては、上型及び中型を垂直上方向にゆっくりと移動させ、中型を取り除いた後に上型を垂直下方向に戻す方法が考えられる。なお、分離剤やビニール等のシート状のものを各型の間に介材させている場合はこれらを利用して分離することも可能である。 FIG. 6 is a view showing a state in which a molten metal space is configured by removing the middle mold and combining the lower mold and the upper mold. Here, as a method of removing the middle mold and aligning the lower mold and the upper mold, it is possible to slowly move the upper mold and the middle mold vertically upward, and after removing the middle mold, return the upper mold to the vertical downward direction.

上述の鋳型の製造方法で得られた鋳型を用いて鋳物を製造する方法について説明する。注湯空間構成ステップで形成された注湯空間に対して、銅合金等からなる溶湯を湯道にゆっくりと流し込み、注湯空間を溶湯で満たす。ここで、注湯空間まで貫通する湯道を上型又は下型の一部に設けて湯を流し込むことが考えられる。そして、溶湯が冷えて固まり固体の銅合金等となるまで十分時間放置する。次に鋳型によってかたどられた銅合金等を上型及び下型から分離するために、上型や下型をハンマー等で外側から叩いて崩していく。そして取り出された銅合金等に対して旋盤加工等で表面を整えて所望の鋳物が得られることになる。 A method of manufacturing a casting using the mold obtained by the above-described mold manufacturing method will be described. A molten metal made of a copper alloy or the like is slowly poured into the runner into the molten metal space formed in the molten metal space forming step, and the molten metal is filled with the molten metal. Here, it is conceivable that a hot water passage penetrating to the pouring space is provided in a part of the upper mold or the lower mold to pour hot water. Then, the molten metal is allowed to stand for a sufficient time until it cools and hardens to become a solid copper alloy or the like. Next, in order to separate the copper alloy or the like formed by the mold from the upper mold and the lower mold, the upper mold and the lower mold are smashed from the outside with a hammer or the like. Then, the surface of the removed copper alloy or the like is prepared by lathe processing or the like, and a desired casting is obtained.

図７は、本実施例の鋳型の製造方法の処理の流れを示すフローチャート図である。この図に示すように、「格子状抜型模型造形ステップ」Ｓ０７０１と「抜型製造ステップ」Ｓ０７０２と「鋳型製造ステップ」Ｓ０７０３と「注湯空間構成ステップ」Ｓ０７０４とからなる。以下、各ステップについて説明する。 FIG. 7 is a flowchart showing a process flow of the mold manufacturing method of the present embodiment. As shown in this figure, it consists of a “grid-shaped die model forming step” S0701, “die cutting manufacturing step” S0702, “mold manufacturing step” S0703, and “pouring space forming step” S0704. Hereinafter, each step will be described.
「格子状抜型模型造形ステップ」Ｓ０７０１では、充填物を上面開口から縦方向に詰め込み可能に板状仕切りで仕切られる複数の区画を備え、複数の区画の上面開口まで目一杯に詰め込まれた充填物の表面によって所望の曲面を造形することができる格子状模型を利用して、下型を製造するための抜き型用の格子状下抜型模型及び上型を製造するための抜き型用の格子状上抜型模型を製造する。「抜型製造ステップ」Ｓ０７０２では、格子状下抜型模型及び格子状上抜型模型を平面に配置して造形に必要な区画を充填物で埋めて固め下抜き型及び上抜き型を製造する。「鋳型製造ステップ」Ｓ０７０３では、下抜き型及び上抜き型の凹部に充填物を詰め込んで固め凹部から抜き出すことで下型及び上型を製造する。「注湯空間構成ステップ」Ｓ０７０４では、下型と上型とを合わせて注湯空間を構成する。 In the “Lattice-shaped die model forming step” S0701, the packing includes a plurality of sections partitioned by plate-like partitions so that the packing can be packed vertically from the upper surface opening, and the packing is packed to the upper surface opening of the plurality of sections. Using a grid model that can form a desired curved surface with the surface of the grid, a grid model for a lower mold for manufacturing a lower mold and a grid pattern for a mold for manufacturing an upper mold Produce top-down models. In the “die cutting manufacturing step” S0702, the grid-like lower die model and the grid-like upper die model are arranged on a plane, and the sections necessary for modeling are filled with a filling material, and the solid lower die and the upper die are produced. In the “mold manufacturing step” S0703, the lower mold and the upper mold are manufactured by filling the recessed parts of the lower punching mold and the upper punching mold with the filling material, and extracting from the recessed parts. In “Pouring the pouring space” step S0704, the pouring space is configured by combining the lower mold and the upper mold.
図８は、格子状下抜型模型の形状とそれを用いて製造される下型用の抜き型（下抜き型）を示す斜視図である。実施例１の格子状下型模型と同様に、格子状下抜型模型は複数の板状仕切りを組み合わせることによって形成されるものであり、板状仕切りで仕切られる複数の区画は鋳物砂等の充填物を上面開口から縦方向に詰め込みが可能な状態になっている。充填物を各区画の上面開口まで詰め込むことによって、所望の曲面を造形することが可能になる。また、実施例１の格子状模型と同様に、複数の区画を仕切る板状仕切りの間隔は一定にする必要はなく、曲率の大きさに応じて各板状仕切りの間隔を調整することが可能である。なお、この図の例では下型用の抜き型（下抜き型）を製造する様子を示しているが、上型用の抜き型（上抜き型）を製造する工程も同様である。 FIG. 8 is a perspective view showing the shape of a lattice-like lower die model and a lower die (lower die) manufactured using the same. Similar to the lattice-shaped lower mold model of the first embodiment, the lattice-shaped lower mold model is formed by combining a plurality of plate-shaped partitions, and the plurality of sections partitioned by the plate-shaped partitions are filled with foundry sand or the like. The object can be packed vertically from the top opening. A desired curved surface can be formed by packing the filling material up to the upper surface opening of each section. Further, similarly to the lattice model of the first embodiment, it is not necessary to make the intervals between the plate partitions that divide the plurality of compartments constant, and it is possible to adjust the intervals between the plate partitions according to the size of the curvature. It is. Although the example of this figure shows a state where a lower die (lower die) is manufactured, the process of manufacturing an upper die (upper die) is the same.
また、実施例１で説明したように、各板状仕切りを製造する方法としては、ＣＡＤ等のプログラムにより加工データ（各板状仕切りの縦横の長さや切り込みの位置等のデータ）を作成し、当該データに基づいて一般的な工作機で作成する方法が考えられる。 In addition, as described in the first embodiment, as a method of manufacturing each plate-like partition, processing data (data such as the length and width of each plate-like partition and the cutting position) is created by a program such as CAD, A method of creating a general machine tool based on the data can be considered.
図９は、上記の工程で製造された下抜き型の凹部に充填物を詰め込んで固めた状態と、凹部から固められた充填物を取り出して載置した状態を示した図である。凹部から取り出された充填物は下抜き型の曲面を片面に写し取っており、下型として所望の曲面を有する。なお、上型も同様の工程により製造可能であり、上抜き型の曲面を片面に写し取っている。 FIG. 9 is a view showing a state in which the filling material is packed into the concave portion of the lower die manufactured in the above-described process and hardened, and a state in which the filling material solidified from the concave portion is taken out and placed. The filling taken out from the concave portion has a curved surface of the lower die on one side, and has a desired curved surface as the lower die. The upper die can be manufactured by the same process, and the curved surface of the upper die is copied on one side.
ここで、下抜き型（上抜き型）に詰め込まれた充填物と下抜き型（上抜き型）の凹部に詰め込まれる充填物を分離しやすくするように、下抜き型（上抜き型）の凹部の表面に分離剤を塗布することや、ビニール等のシート部材を介在させておくことが好ましい。また、実施例１で説明したように、充填物として鋳物砂を用いる場合は、鋳物砂を硬化させるための処理を行うことも可能である。なお、凹部から下型（上型）が取り出された後の下抜き型（上抜き型）は再度利用することも可能であり、同種の鋳型を複数製造することも可能である。 Here, in order to make it easy to separate the filling packed in the lower punching die (upper punching die) and the filling packed in the concave portion of the lower punching die (upper punching die), It is preferable to apply a separating agent to the surface of the recess or to interpose a sheet member such as vinyl. Moreover, as described in Example 1, when using foundry sand as a filler, it is also possible to perform a process for curing the foundry sand. Note that the lower die (upper die) after the lower die (upper die) is taken out from the recess can be reused, and a plurality of the same type of molds can be produced.
図１０は、上記の工程で製造された下型と上型を所望の曲面が向かい合うように合わせた状態を示した図である。ここで、上型と下型の間には点線で示す注湯空間が構成されている。つまり、実施例１のように中型を製造する必要はなく、抜き型によって製造された上型と下型を所定の位置関係で配置することによって注湯空間を構成することが可能である。また、この際に各型が型崩れしないように予め充填物を硬化させるための処理を行っておくことが好ましい。 FIG. 10 is a view showing a state in which the lower mold and the upper mold manufactured in the above process are combined so that desired curved surfaces face each other. Here, a pouring space indicated by a dotted line is formed between the upper mold and the lower mold. That is, it is not necessary to manufacture the middle mold as in the first embodiment, and it is possible to configure the pouring space by arranging the upper mold and the lower mold manufactured by the punching mold in a predetermined positional relationship. At this time, it is preferable to perform a treatment for curing the filler in advance so that the molds do not lose their shape.

Here, it is preferable that one compartment is closed with one lid, but it is also possible to close a plurality of compartments with one lid. Further, the plate-shaped partition and the lid are not necessarily made of the same material, and different materials can be used.
板状仕切りの区画の上面開口を蓋で閉じる方法としては、各区画の上面開口と蓋を接着材や連結部材等を用いて連結する方法も可能であるし、例えば図１２に示すように各蓋を可動連結部材を用いて連結する方法や、これらの方法を組み合わせた方法も考えられる。その他の工程は、基本的に実施例２で示した工程と同様であるから、説明を省略する。 As a method of closing the upper surface opening of the partition of the plate-like partition with a lid, a method of connecting the upper surface opening of each partition and the lid using an adhesive or a connecting member is also possible.

<Overview>
The mold manufacturing method of the present embodiment is basically the same as the manufacturing method of Embodiments 1 to 3, but is characterized in that it is a method of manufacturing a propeller blade mold using a lattice model. Since the lattice model is composed of plate-shaped partitions that can be manufactured by a general machine tool, it is easy to manufacture, and a mold having a complicated curved surface can be used even by those who do not have skilled skills. It can be manufactured in a short period of time.
本実施例の鋳型の製造方法では、下型と上型とを合わせて形成される注湯空間がプロペラ翼となることを特徴としている。一例として、複数のプロペラ翼の鋳型を同時に用いて固定ピッチプロペラを鋳造する例を示しているが、例えば一のプロペラ翼を鋳造し可変ピッチプロペラの部品とすることも可能である。また、本実施例では、下型については実施例２又は３で説明した格子状下抜型模型を利用して製造し、注湯空間（中型）については実施例１で説明した格子状注湯空間模型を利用して形成し、上型は中型の上に充填物を盛りつけて固める方法で製造しているが、他の組み合わせ方も当然に可能である。 The casting mold manufacturing method of the present embodiment is characterized in that the pouring space formed by combining the lower mold and the upper mold is a propeller blade. As an example, an example in which a fixed pitch propeller is cast using a mold of a plurality of propeller blades at the same time is shown.

Further, in this embodiment, the lower mold is manufactured using the grid-shaped undercut model described in the second or third embodiment, and the pouring space (medium mold) is the grid-shaped pouring space described in the first embodiment. The upper mold is made by using a model, and the upper mold is manufactured by placing the filler on the middle mold and solidifying it, but other combinations are naturally possible.

By pouring molten metal made of copper alloy or the like into the runway, the pouring space is filled from below with the molten metal. Then, by allowing it to stand for a sufficient time, the molten metal cools and solidifies to form a solid object having the shape of a propeller blade. Next, in order to separate the solid matter of the propeller blade from the upper mold and the lower mold, the upper mold and the lower mold are smashed from the outside with a hammer or the like. Then, a lathe process is performed on the taken-out solid material to prepare a surface, and a desired propeller as shown in FIG. 16 can be manufactured.
