上述した金型１の製造方法を、第２図を参照して説明す
る。なお、この図は、上記第１図の金型１の製造方法の
例を示している。A method of manufacturing the mold 1 described above will be explained with reference to FIG. 2. Note that this figure shows an example of a method for manufacturing the mold 1 shown in FIG. 1 above.
この金型１は、基台１０．枠体１１及び蓋体１２からな

１ｂに接続された湯溜り１４とを用いて行なわれる。This mold 1 has a base 10. A mold (mold) 13 consisting of a frame 11 and a lid 12, and a frame 1 with an open sprue 11a.
This is carried out using a hot water reservoir 14 connected to 1b.
先ず、金型本体２を第１図に示す上下位置が反対となる
ように、すなわち、つば部２ａが下側となるように基台
１０に載置する。First, the mold body 2 is placed on the base 10 so that the vertical position shown in FIG. 1 is reversed, that is, with the collar portion 2a facing downward.
次いで、冷却用パイプである銅パイプ５を金型本体２の
外周に巻回する。なお、冷却用パイプ５を予め巻回した
金型本体２を基台１０に載置するようにしてもよい、銅
パイプは、折り曲げ容易性と熱伝導性において優れてい
るので、冷却用パイプとして好ましい。Next, a copper pipe 5 serving as a cooling pipe is wound around the outer periphery of the mold body 2. Note that the mold body 2 with the cooling pipe 5 wound in advance may be placed on the base 10. Copper pipes are excellent in ease of bending and thermal conductivity, so copper pipes may be used as cooling pipes. preferable.
その後、金型本体２の外径よりも所定寸法大きな内径を
有し、かつ金型本体２の高さとほぼ等しい深さを有する
枠体１１を金型本体２にかぶせて基台１０に載置し、さ

２間を固定する。このようにして、基体１０の上面、枠
体１１の内周壁面、蓋体１２の下面及び金型本体２の外
周壁面とによりキャビティ１５が形成される。Thereafter, a frame 11 having an inner diameter a predetermined dimension larger than the outer diameter of the mold body 2 and a depth approximately equal to the height of the mold body 2 is placed over the mold body 2 and placed on the base 10. Then, the lid body 12 is placed on the frame body 11, and the base body 10 and the lid body 1 are
Fix the gap between the two. In this way, the cavity 15 is formed by the upper surface of the base 10, the inner peripheral wall surface of the frame 11, the lower surface of the lid 12, and the outer peripheral wall surface of the mold body 2.
そして、湯溜り１４にキャビティ１５の容量とほぼ等し

形成されたら、基台１０．枠体１１及び蓋体１２とを分
離して金型１が得られる。Then, a molten metal a of A1 alloy approximately equal to the capacity of the cavity 15 is poured into the molten metal sump 14, and the rotating shaft 16 provided on the frame 11 is rotated in the direction of the arrow to pour it all at once into the cavity 15 from the sprue 11a, i.e. , cast by tilt casting method. Thereafter, when the molten metal is cooled and solidified to form the cooling body 4, the base 10. The mold 1 is obtained by separating the frame 11 and the lid 12.
Ａ１合金が固結すると、金型本体２の上下端に設けられ
たつば部２ａ、２ｂにより冷却体は金型本体２から外れ

一体的に構成される。なお、つば部２ａ、２ｂを省略し
、金型本体２の外周壁面に凹凸を設けてもよい。When the A1 alloy solidifies, the cooling body 2 does not come off from the mold body 2 due to the flanges 2a and 2b provided at the upper and lower ends of the mold body 2, so that the mold body 1 and the cooling body 4 are integrated. It is composed of Note that the flange portions 2a and 2b may be omitted, and the outer peripheral wall surface of the mold body 2 may be provided with irregularities.
また、冷却用パイプ５は銅製であるため、Ａ１より融点
が高くＡ１合金の鋳込によって溶解するおそれはないと
ともに、可傾ｉ遣方法によりＡ１合金が鋳込まれるため
、冷却用パイプ５の溶融は効果的に防止される。なお、
銅パイプの代りにＡＩパイプであってもよい。Furthermore, since the cooling pipe 5 is made of copper, its melting point is higher than that of A1, so there is no risk of melting when A1 alloy is cast. is effectively prevented. In addition,
An AI pipe may be used instead of a copper pipe.
この場合であっても、可傾鋳造方法であるとＡ１パイプ
が溶解する前にＡ１合金の溶湯が固結するので、冷却水
の通路は確保される。Even in this case, if the tilt casting method is used, the molten metal of the A1 alloy solidifies before the A1 pipe melts, so that the cooling water passage is secured.
Ａ１合金の鋳込時には、Ａ１合金の溶湯が冷却用パイプ
５の両端から侵入しないようにＡ１合金より融点の高い
材質の部材で密閉される。勿論、この両端５ａ、５ｂを
枠体１１の外側まで伸ばしておくようにしてもよい。When A1 alloy is cast, the cooling pipe 5 is sealed with a member made of a material having a higher melting point than the A1 alloy so that the molten metal does not enter from both ends of the cooling pipe 5. Of course, both ends 5a and 5b may be extended to the outside of the frame 11.
以上のように、本発明に係る金型１は、基台１０．枠体

冷却パイプ５を溶融させることがない。As described above, the mold 1 according to the present invention includes the base 10. The frame body 11 and the lid body 12 constitute a mold, the mold body 2 around which the cooling pipe 5 is wound is used as a core, and the mold can be easily manufactured by casting molten metal of A1 alloy into the core. At the same time, since this casting is performed using the tilt casting method,
The cooling pipe 5 will not be melted.
