Description of the Related Art Conventionally, it has been desired to lower the center of gravity of a club head of a golf club from the viewpoint of extending flight distance and stabilizing directionality. For example, in club heads made of metal such as iron and metal wood, there are methods such as devising the cross-sectional shape to lower the center of gravity, and attaching a material with a higher specific gravity than the material of the main body to a lower position of the main body. It is considered. FIG. 17 shows a conventional club head for a golf club, which is made of a composite material that lowers the center of gravity of the club head by using a main body and a material having a higher specific gravity. The club head of a golf club made of a composite material is composed of two types of members: a head body 40 having a recess 42 formed on the bottom surface and a member 44 having a higher specific gravity than the head body 40. The head body 40 is manufactured by forging or the Lost wax wax casting method.
If a member 44 having a larger specific gravity than the head body 40 is fitted and fixed in the recess 42 on the bottom surface of the head body 40, the center of gravity of the club head can be made lower than that of one made of one material.

In a club head made of a composite material in which a weight 44 having a larger specific gravity is fixed in the recess 42 on the bottom surface of 0, the weight of the weight 44 must be changed when changing the center of gravity. When it is desired to keep the total weight of the club head constant, the weight of the head body 40 changes as the weight 44 changes, and as a result, the shape of the head body 40 must be changed.

With the upper mold and the lower mold that form a space for casting the head main body, the core is sandwiched and the weight is located in the space, and liquefied wax is injected into the space to form a space. After covering the weight and cooling and solidifying the wax, the mold is removed, the wax and the core protruding to the outside of the wax are covered with molding sand, and then the wax is liquefied from the inside of the molding sand. The material of the head body was liquefied and flowed into the molding sand to form a solidified head body with the weight positioned inside, and then the molding sand was removed and solidified. From the head body Core was removed, it is obtained by a hole to remove the core so as to fill in the filling member.

2 can be cast, and it is possible to eliminate the conventionally required fitting portion between the head body and the weight. Therefore,
The dimensional accuracy of the fitting portion required for the club head of the conventional golf club made of the composite material is not required. Further, since the polishing process is performed only on the cut portion of the support arm 14, the polishing portion can be reduced as compared with the conventional one. In the club head of the conventional golf club made of a composite material, when changing the position of the center of gravity, the weight of the head main body had to be increased or decreased, and the shape of the head main body had to be changed. In the club head of a golf club, since the weight of the entire club head does not change even if the position of the center of gravity is changed, it is not necessary to change the shape of the head body.

After that, a filling member 34 preferably made of the same material as that of the head main body 16 is put into the carved hole of the core 32 to fill the hole, and the filling member 34 is fixed to the head main body 16 with an adhesive or the like. The method of filling the hole formed by carving out the core 32 is not limited to this.

になる。When a club head for a golf club is manufactured by the above method, the weight 3 is placed inside the head body 16.
Since 0 is cast, the dimensional accuracy for fitting the head body and the weight, which has been required in the past, becomes unnecessary. Further, since the polishing process only needs to be performed on the hole portion where the core 32 is cut out, the number of polishing points can be reduced as compared with the conventional one. Furthermore, the position of the center of gravity can be changed without changing the shape of the head body.

のクラブヘッドでは、重心の位置を変えてもクラブヘッ
ド全体の重量が変化しないので、ヘッド本体の形状を変
えること無く重心の位置を変えることが可能になる。As described above, according to the method of manufacturing the club head of the golf club made of the composite material according to the present invention, when the head body is cast by the lost wax casting method, the weight is placed inside the head body. It was designed to be housed. This eliminates the conventional fitting portion between the head body and the weight, which eliminates the need for dimensional accuracy in the conventional fitting portion and reduces the manufacturing cost. Further, since the polishing process only needs to be performed at the position of the support arm for supporting the weight in the internal space of the mold, the number of polishing points can be reduced as compared with the conventional one. Further, in the club head of the golf club according to the present invention, even if the position of the center of gravity is changed, the weight of the entire club head does not change, so that the position of the center of gravity can be changed without changing the shape of the head body.

A head body, which has a larger specific gravity and a higher melting point than that of the head body, and in which a weight and a supporting arm are integrally formed, is provided to form a space for casting the head body. The supporting arm is sandwiched between a mold and a lower mold, and the weight is positioned in the space, and liquefied wax is injected into the space to cover the weight with wax, and the wax is cooled to be solid. After that, the mold is removed, the wax and the supporting arm protruding to the outside of the wax are covered with casting sand, and then the wax is liquefied and removed from the inside of the casting sand, and the head body is placed inside the casting sand. The material is liquefied and flows in to form a solidified head body with the weight positioned inside, then removes the foundry sand and cuts the supporting arm protruding outside the solidified head body.
