（ダイカスト）等が知られている。As a casting method, there is gravity casting, in which molten metal (molten metal) is poured into a mold and cast using gravity, and molten metal t%
Pressure casting (die casting), in which a material is press-fitted into a mold at a pressure higher than atmospheric pressure, is known.
これらの鋳造方法は、鋳物の形状や大きさ、それに外観

種々の利点があるが、重力鋳造では一般にブローボール
、ひけ１ｖ等の欠陥を防ぐために大量の押湯が必要で、
したがって利料の歩留りが悪く、鋳型もある程度大きく
なってしまり。These casting methods are selected depending on the shape and size of the casting, appearance, precision, mass production, etc., and each has various advantages, but gravity casting generally prevents defects such as blow balls and sink marks. A large amount of boiling water is required to
Therefore, the yield of interest is poor and the mold becomes large to some extent.

しいので注湯後の攪拌を必要とし、工数がかかると共に
、その攪拌の程度によって欠陥が生じかねない。In addition, in the pressure aQ structure, it is difficult to remove the flux.
Therefore, it is necessary to stir the metal after pouring, which takes a lot of man-hours and may cause defects depending on the degree of stirring.

まで削り落としている。For example, when welding 111i1 alloy 2 on the surface of a disk-shaped @IAI as shown in Fig. 1, a large mold 3 as shown in Fig. 2 is used in gravity casting. Fix the preparation 1 in the container and pour in the molten copper alloy. After solidification, the excess copper alloy 2 is shaved off to a predetermined size.
銅合金２の仕上り厚さが薄いにもかかわらず。Despite the thin finished thickness of Copper Alloy 2.
これによる歩留りは極めて悪く、せいぜい５％（ｉ′Ｉ

その攪拌状態によっては欠陥が生じて、特に異種金属間
の溶着力（結合力）乙・ご不安を残１−でいた。On the other hand, in pressure casting, as shown in Fig. 3, the mold 4 is small and the molten metal is pressed by the plunger 5, so less molten metal is required, but as mentioned above, the stirring time is long and slow. Defects may occur depending on the condition, and the welding strength (bonding strength) between dissimilar metals is particularly worrying.
本発明は、このような点に着目し７てなされたもので、

発生を防止することを目的とする。The present invention has been made by paying attention to these points.
The purpose is to uniformly stir the molten metal by applying vibration after pressure casting, to reduce the number of man-hours, and to prevent the occurrence of each i defect.

゛ラン・ジャである。Hereinafter, the present invention will be explained based on the drawings. Fig. 4 shows the principle of the present invention, and 6 is a metal mold (mold);
7 This is a flange that presses the molten metal poured into the mold 6 of the cigarette.
このプランジャ７は、油圧等により駆動され、上方から
金型６内に進入して溶湯に所定以上（例えば７ｋｙ／ｃ
ｎＩ以上）の圧力を加える。This plunger 7 is driven by hydraulic pressure or the like, and enters into the mold 6 from above and presses the molten metal over a predetermined amount (for example, 7ky/c).
Apply a pressure of nI or more.

A predetermined vibration is applied, for example, in the direction of the arrow by a motor or the like. The strength, frequency, etc. of this excitation force are selected depending on the shape and size of the mold 6 and the amount of molten metal. .

なからその中に溶湯（銅合金）を注き゛込む。- Then, as an example of the construction of a furnace by this method, as shown in the above-mentioned No. 1 M, when the surface of the steel material 1 is fully welded, the K (g) alloy 2 is completely welded. Push it into the mold 6, install it (preheat it in a furnace, etc. (e.g. E) 00 to 850"C) 7. After this preheating, place the mold 6 on a shaking table 8+), and Add the shake i1+ of il,
Therefore, molten metal (copper alloy) is poured into it.

ャ７をはずし、金型Ｇから製品を取出すのである。When the molten metal begins to have the same size due to natural cooling and enters the solid-liquid coexistence region, the silane 7 is fully lowered to apply pressure above a predetermined level to the molten metal. Thereafter, when the product is completely solidified, the plunger 7 is removed and the product is removed from the mold G.

As shown in Table 1 and Table 2, when compared with those produced by the three manufacturing methods, the tl and porosity of the present invention are high and sufficiently superior. The shear strength was measured using a testing machine as shown in Fig. 5, with the steel material 1 fully fixed to the jig 9, and a lateral load applied to the welded part 10 with the piston 11, and the fracture strength was measured. .
