を意味し、実質的に一個ずつの成形品と同じであった。"Prior Art" Conventionally, in molding methods using metal molds such as forging and casting, molded products have been formed one by one and processed one by one. Also, what is usually called two-cavity molding means that the same molded product as an individual molded product is simply molded into two pieces, and is substantially the same as a single-cavity molded product.

。For example, one conventional example of a cap for a safety valve of an LP gas container valve is as shown in Figures 21 to 23,
This will be explained. A hole 1 is formed in the main body with a predetermined finishing allowance provided for the cap 101a] 01 in consideration of the finishing allowance.

It was a brass forging molded product with 4. And the main body 10
] is held in a non-rotating chuck, and the hole 102 is cut by rotating the cutting tool.
was finished by cutting as shown in Figure 23. Also, in order to shorten the molding cycle time, two-cavity molding of products of the same shape was performed. In order to shorten the cutting cycle time, an indexing device was used to perform simultaneous multi-step cutting. In addition, for caps such as flare nuts for refrigerators, small caps were machined from rod material, while larger caps were forged from brass or other materials.

「発明が解決しようとする問題点」
ところでこの様な従来の金型によるキャップ類の成形方
法は次の欠点を持っていた。"Problems to be Solved by the Invention" However, the conventional method of molding caps using a mold has the following drawbacks.
鍛造、鋳造等による成形品は多数個取りが行なわれるこ

留りが悪くなり、必ずしも安価な成形品が供給出来ると
は限らなかった。もちろん、材料の流動がスムーズでな
く、充填不足による欠肉等でクラックが発生しやすく、
重大欠陥である漏れにつながることが多かった。Molded products made by forging, casting, etc. are often made into multiple pieces, but this is just two or three pieces of the same molded item laid out in parallel. A portion of the overflow is increased, which actually worsens the yield, and it is not always possible to supply inexpensive molded products. Of course, the flow of the material is not smooth, and cracks are likely to occur due to lack of material due to insufficient filling.
This often led to leaks, which is a serious defect.
又、成形金型にも無理がかかり金型寿命は大幅に短かく
なってしまっていた。Moreover, the molding die was also strained, and the life of the die was significantly shortened.
この発明は上記事情にかんがみて創案されたもので、背

In addition, molding methods using molds such as aluminum die casting, powder metallurgy molding, lost wax molding, etc. can also be performed by a two-cavity molding method in which back-to-back connections are made. Then, the caps, which are simultaneously machined from both end faces and cut into the back-facing connecting part, are separated into two by finish processing, and are used as spring holders, caps for safety valves, etc., mainly in valves. It functions as a flare nut for fastening connections, as a base to prevent leaks, as a retainer, and as a guide shade.

The figure shows the machined state. In this embodiment, a rod-shaped main body 1 in which two caps 1a, which are union nuts, are connected facing each other on the back is provided with a shallow hole 2.2 with a small diameter corresponding to the finishing component at both ends, and a hole 2.2 with a shallow diameter corresponding to the finishing component is provided at both ends of the rod-shaped body 1, in which two caps 1a, which are union nuts, are connected oppositely to each other. The cutting allowance for cutting is 3. Note that the cap 1a is usually formed by brass forging. After cutting, the valve 5, which is a fan coil valve, is screwed to the valve 5, which is a fan coil valve, with a gas get and a cap 1b, which is a union nipple, interposed therebetween for leak-proof fastening. In addition, from the viewpoint of material yield, the larger the size, the greater the cost advantage. 9 Figures 13 to 15 show a union nipple for a fan coil valve, which is yet another embodiment of the present invention, and Figure 12 shows the same actual performance. In this example, Fig. 13 shows a left side view, Fig. 14 shows a front sectional view, and Fig. 15 shows a cut surface. The two caps 1b, which are union nipples, are connected with holes 2 at both ends of the rod-shaped main body 1, which is connected to the back facing each other.
2 is provided, and the opposing connecting portion in the center is used as the cutting allowance 3 for cutting. Incidentally, on the inner side wall of the hole 2.2, molded concavo-convex portions 4.4, each of which is a protrusion, are provided for tool hooks in the opposing axial direction. Note that the cap 1b is usually formed by brass forging. After cutting, the valve 5, which is a fan coil valve, is pressed and held with a cap 1a, which is a union nut, with a gasket interposed therebetween for connection to a pipe. In this embodiment, the cap 1a is replaced with the union nut cap 1a in FIG.

Furthermore, in this molding method, the same molded products may not be connected back to face each other, but separate molded products of different shapes may be connected to each other in back to face opposition. Furthermore, it is also possible to grab a large number of objects connected with their backs facing each other. The present invention also applies to forging methods such as hot forging, warm forging, and cold forging, shell mold casting, 1-type force casting, die casting, lost wax casting, and other mold forming methods such as powder metallurgy. The following molding methods can be applied.

．． Hole 2.2 can be formed by machining holes 2.2 at the same time, and in the final process, finishing the back surface of the caps la and cutting off with cutting allowance 3. Alternatively, the main body 1 can be chucked non-rotatingly and the tool can be rotated to cut the hole 2.2. It is also possible to use a processing method in which the main body 1 is rotated in the final step to finish the back surface of the caps la and cut off the cutting allowance 3. In addition, when cutting the back facing connecting part of a molded product, if it has a through hole, an internal burr will occur in the through hole, so in the previous process, the annular groove is cut by recessing with a cutting tool from the hole 2 side. What is necessary is to provide it so that it can be chamfered after cutting.

With the back-to-back connection method, the product becomes a rod-shaped molded product, and the material flows straight and smoothly, without complicated flows, so there is no underfilling or entrainment, and it is highly strong and resistant to cracks and leaks. Becomes the property of or,
The molding die does not need to have a back surface of the cap, and is simple in shape, inexpensive, and has a long mold life. Furthermore, in forging, there is less overflow of material from the dividing surface of the mold, and the material yield is greatly improved.
さらに、鋳造に於いては、二個のキャップにつき一箇所

幅な加工能率アップとなる。Furthermore, in casting, only one sprue is required for each two caps, which greatly improves the material yield, similar to forging. Furthermore, during machining, this molded product is easy to chuck, and even when chucked by a robot, it can be chucked twice as much in the same cycle as before, greatly increasing machining efficiency.
