により一体構造での製作が困難である。[Prior Art] In recent years, Ti alloys have been widely used as golf head materials, but it is difficult to manufacture Ti alloy golf heads with an integral structure for the following reasons.
■ 薄肉部、特にソール部に湯が回り難い。■ It is difficult for hot water to flow to thin parts, especially the sole part.
■ ワックスパターン製作時の中子の固定が困難である
。■ It is difficult to fix the core when making wax patterns.
■ 中子の型バラン（砂抜き）が困難である。■ It is difficult to balance the core (remove sand).

高精度に製品品質を維持することが困難となる。特に、
ゴルフヘッドに要求される微妙なバランスが損なわれ、
要求品質を満足し得ない製品となるおそれもある。In addition, in the case of a head with a welded structure, since the sole part 11 is welded, differences in weld penetration in the sole part 11 cause variations in weight, balance, etc. for each product, and product quality can be maintained with high precision throughout all products. It becomes difficult to maintain. especially,
The delicate balance required of a golf head is impaired,
There is also a risk that the product will not meet the required quality.

ことを特徴とする。[Means for Solving the Problems] A method for manufacturing an integrated Ti alloy golf head of the present invention includes:
A method for integrally casting a Ti alloy hollow golf head using a mold manufactured by a lost wax method in which a wax pattern is created by injecting wax into a mold in which a core is placed, the core comprising: A core is made of a calcia material and has a protrusion for fixing the core formed in a portion corresponding to the balance adjustment screw hole on the sole surface of the golf head, and the protrusion for fixing the core is fitted into the mold. A golf head is obtained by forming possible recesses, manufacturing a mold by a lost wax method using this core and mold, casting using this mold, and then hydrating and removing the core. It is characterized by

。Furthermore, since it is an integrated type, sole welding and the like are not required, and there is no risk of problems such as variations in product quality, deterioration of accuracy, and imbalance due to welding. Moreover, in the method of the present invention, since the core material is a calcia material,
The molding of the core can be easily carried out by contacting the obtained casting with water or steam, utilizing the hydration reaction of Ca O+H20-+ Ca (OH) +1. Moreover, since the core is stably fixed by fitting the core fixing protrusion with the recess of the mold, the core does not wobble during wax injection. For this reason, the hot water circulation is also improved.
