Description

【０００１】
【発明の属する技術分野】
本発明は、鋳物を鋳造するに当たり、鋳型として用いられる金型およびその製造方法並びにその金型による鋳造方法に関する。
【０００２】
【従来の技術】
従来、鋳物を鋳造するために用いる鋳型としては、鋳鉄製のバックアップ部材に特殊の塗型剤を塗布して成る金型や、鋳物砂で造型した砂型がある。
【０００３】
【発明が解決しようとする課題】
しかし、前者の金型では、注入された溶融金属が急冷されるため鋳物表面がチル化し、しかも、通気性が悪いために鋳物にガス欠陥が生じ、その上、耐久性がないなどの問題があった。また、後者の砂型では、多量の鋳物砂を循環して使用するために大型で高価な砂処理設備が必要な上に作業環境が極めて悪く、しかも、注入された溶融金属の冷却のコントロールが困難なため冷却ラインが非常に長くなるなどの問題があった。
【０００４】
本発明は上記の事情に鑑みてなされたもので、第１の目的は、注入された溶融金属の冷却のコントロールが自由自在であり、しかも鋳物砂の使用量が極めて少ない上に鋳物にガス欠陥が生じることのない鋳造用金型を提供することにある。第２の目的は、通気性を有する鋳造用金型を容易に製造することができる金型の製造方法を提供することにある。第３の目的は、金型に注入された鉄溶湯の冷却のコントロールを容易かつ確実に行うことができる鋳造方法を提供することにある。
【０００５】
【課題を解決するための手段】
上記の目的を達成するために請求項１の鋳造用金型は、鋳物を鋳造するに当たり、鋳型として用いられる金型であって、鋳物製品の外形に対応した製品キャビティ面を有しかつこの製品キャビティ面にこれの背面と連通する通気機構を設けた金属製の母体と、前記製品キャビティ面に被覆された通気性を有する鋳物砂製の被覆層と、を備えたことを特徴とする。
【０００６】
また、請求項８の鋳造用金型の製造方法は、鋳物を鋳造するに当たり、鋳型として用いられる金型を製造する方法であって、製品の外形よりほぼ相似的に大きい寸法の製品キャビティ面を有しかつこの製品キャビティ面にこれの背面と連通する通気機構を設けた金属製の母体と前記製品キャビティ面に被覆された通気性を有する鋳物砂製の被覆層とで成る金型と、製品模型との間隔であって前記製品キャビティ面にほぼ沿って延びる空間を画成する工程と、前記空間に前記製品キャビティ面を被覆する鋳物砂を充填する工程と、充填された鋳物砂を硬化させる工程と、前記鋳物砂の硬化後硬化した鋳物砂を前記母体側に付着させた状態で母体を前記製品模型から分離する工程と、を含むことを特徴とする。
【０００７】
また、請求項１１の金型による鋳造方法は、請求項１〜６のうちいずれか１項に記載の鋳造用金型を用いて鋳造する方法であって、前記鋳造用金型によって画成したキャビティ内に注湯した後、前記金型からの吸引または気体の吹き込みにより前記キャビティ内の溶湯を急冷することを特徴とする。
【０００８】
【発明の実施の形態】
なお、本発明において鋳物とは、原料が普通鋳鉄、ダクタイル鋳鉄、アルミニウム等であるものをいう。またなお、請求項１の母体の製品キャビティ面が、鋳物製品の外形に対応しかつ製造の容易性により決定されるようになっていて、この製品キャビティ面が薄肉（例えば、肉厚が２〜５ｍｍ）状態で突起する部分を有する場合にはこの薄肉部分を省略し、前記母体の製品キャビティ面における薄肉部分によって形成されるべき個所は、被覆層によって形成するようにする。
【０００９】
またなお、請求項１の鋳造用金型における母体は、製品キャビティ面にこれの背面と連通する通気孔、ベントプラグ等の通気機構を設けることにより、注湯時のガスを排出させたり、被覆層を介して気体状の冷却媒体を溶融金属に適用することができる。またなお、前記母体における冷却手段として、表面の面積を拡張すべくフィンを突設したり、製品キャビティ面の背面に冷却媒体貯蔵用の空間を形成することができる。
【００１０】
またなお、請求項１の鋳造用金型において、被覆層の厚みは１〜２０ｍｍが好ましく、より好ましくは４〜１０ｍｍである。１ｍｍ未満では被覆手段としての機能を発揮することができず、
また２０ｍｍを越えると通気性が悪くなる。またなお、請求項１の被覆層は、自硬性鋳物砂、ガス硬化性鋳物砂またはシェル砂で成るものであって、耐熱性および通気性を有することが望ましい。特に自硬性鋳物砂、ガス硬化性鋳物砂を用いた場合には、複雑な加熱手段が不要であり、しかも鋳型の通気性もよいためプロセスがより簡単になる。さらになお、前記被覆層は、シリカ系またはアルミナ系の鋳物砂で形成することにより、安価に製造することができる。

【００１５】
また、請求項８の鋳造用金型の製造方法は、鋳物を鋳造するに当たり、鋳型として用いられる金型を製造する方法であって、製品の外形よりほぼ相似的に大きい寸法の製品キャビティ面を有しかつこの製品キャビティ面にこれの背面と連通する通気機構を設けた金属製の母体と前記製品キャビティ面に被覆された通気性を有する鋳物砂製の被覆層とで成る金型と、製品模型との間隔であって前記製品キャビティ面にほぼ沿って延びる空間を画成する工程と、前記空間に前記製品キャビティ面を被覆する鋳物砂を充填する工程と、充填された鋳物砂を硬化させる工程と、前記鋳物砂の硬化後硬化した鋳物砂を前記母体側に付着させた状態で母体を前記製品模型から分離する工程とを含むから、通気性を有する鋳造用金型を容易に製造することができる。

However, in the former mold, the casting metal surface is chilled due to rapid cooling of the injected molten metal, and gas defects occur in the casting due to poor air permeability. there were. In addition, the latter sand mold requires large and expensive sand treatment equipment because a large amount of foundry sand is circulated and used, the working environment is extremely poor, and it is difficult to control the cooling of the injected molten metal. Therefore, there has been a problem that the cooling line becomes very long.
[0004]
The present invention has been made in view of the above circumstances, and a first object of the present invention is to freely control the cooling of injected molten metal, to use a very small amount of molding sand, and to reduce gas defects in the casting. It is an object of the present invention to provide a casting mold that does not cause any problem. A second object is to provide a method of manufacturing a mold that can easily manufacture a casting mold having air permeability. A third object is to provide a casting method capable of easily and reliably controlling the cooling of the molten iron injected into the mold.

A metal mold having a metal base provided with a ventilation mechanism communicating with the rear surface of the product cavity surface and a coating layer made of air-permeable molding sand and covering the product cavity surface; Defining a space spaced from the model and extending substantially along the product cavity surface; filling the space with molding sand covering the product cavity surface; and curing the filled molding sand. And a step of separating the mother body from the product model with the foundry sand hardened after the foundry sand is adhered to the body side.
[0007]
A casting method using a mold according to claim 11 is a method for casting using the casting mold according to any one of claims 1 to 6, wherein the casting method is defined by the casting mold. After pouring into the cavity, the molten metal in the cavity is rapidly cooled by suction from the mold or blowing of gas.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
In the present invention, the casting refers to a material whose raw material is ordinary cast iron, ductile cast iron, aluminum or the like. Further, the product cavity surface of the base according to claim 1 corresponds to the outer shape of the casting product and is determined by the ease of manufacture, and the product cavity surface is thin (for example, having a thickness of 2 to 2). In the case where a portion projecting in a 5 mm) state is provided, this thin portion is omitted, and a portion to be formed by the thin portion on the product cavity surface of the base is formed by a coating layer.
[0009]
Further, the base in the casting mold of claim 1 is provided with a ventilation mechanism such as a vent hole and a vent plug communicating with the back surface of the product cavity surface to discharge gas at the time of pouring or cover the product. A gaseous cooling medium can be applied to the molten metal via the layers. In addition, as a cooling means in the base body, fins may be protruded to expand the surface area, or a space for storing a cooling medium may be formed on the back surface of the product cavity surface.
[0010]
In addition, in the casting mold of claim 1, the thickness of the coating layer is preferably 1 to 20 mm, more preferably 4 to 10 mm. If it is less than 1 mm, it cannot function as a coating means,
If it exceeds 20 mm, the air permeability becomes poor. Further, the coating layer of claim 1 is made of self-hardening molding sand, gas-curing molding sand or shell sand, and desirably has heat resistance and air permeability. In particular, when self-hardening molding sand or gas-curing molding sand is used, a complicated heating means is not required and the process is simpler because the mold has good air permeability. Furthermore, the coating layer can be manufactured at low cost by forming it from silica-based or alumina-based molding sand.
[0011]
【Example】
Hereinafter, a procedure for manufacturing a casting mold of the present invention and a procedure for casting a casting using the mold will be described in detail with reference to the drawings.

The two mother bodies 4, 4 provided with the ventilation holes or vent plugs 3 communicating with the formed hollow chamber 2 on the product cavity surface 1 are arranged so as to face each other with the product model 5 interposed therebetween. As shown in (b), the two mother bodies 4.4 are combined to define a space 6 extending between the mother body 4.4 and the product model 5 or the match plate and substantially along the product cavity surface 1.1. I do.
[0012]
Next, as shown in FIG. 2A, a gas-curable casting as a raw material of a molding sand coating layer that coats the product cavity surface 1 of the mother body 4 by suction by reduced pressure in the space 6 or blowing by compressed air. After the sand 7 is filled in the space 6, a hardening gas is caused to flow through the gas-curable molding sand 7 to harden the gas-curable molding sand 7, and then, as shown in FIG. With the post-cured molding sand 7 adhered to the base 4, the two bases 4 are separated from the product model 5 and separated from each other. Thereby, a desired mold 8 can be obtained. The same applies to not only gas-curable molding sand but also self-hardening molding sand and shell sand.
[0013]
Next, a procedure for casting a casting using the mold 8 will be described. As shown in FIG. 3A, a product cavity is formed by combining two molds 8 composed of a base body 4 and molding sand 7. After defining 9, molten iron 10 (hereinafter, referred to as molten iron 10) is injected into ladle 11 into product cavity 9, and is sucked or blown with compressed air into hollow chamber 2 to melt the molten iron 10. The cooling of the iron 10 is controlled, and subsequently, as shown in FIG. 3B, after the molten iron 9 has solidified, the two dies 8.8 can be opened and a predetermined product 12 can be taken out. In addition, as for the casting which requires a core as an example, the core may be inserted between the molds 8, 8 and poured.
[0014]
