- An object of the present invention is to provide a method of manufacturing a golf club head in which the pressure applied during molding is equalized and the joined state of the composite material is improved.
- the golf club head manufacturing method of the present invention for solving the above-mentioned object also has an uncured fiber-reinforced grease so as to cover the opening with respect to the metal outer shell member having the opening.
- a cover material is applied to form a head intermediate, and the first mold that contacts the outer surface of the head intermediate including the cover material and the outer surface of the head intermediate opposite to the cover material are applied.
- the head intermediate body is sandwiched between the second mold and the second mold, and the head intermediate body is heated while applying an internal pressure to the head intermediate body via a bladder and a press pressure between the first mold and the second mold.
- the opening is covered with respect to a metal outer shell member having an opening in the crown and a flange around the opening.
- a cover material made of uncured fiber reinforced resin is applied to form a head intermediate, and the first mold that contacts the outer surface of the crown of the head intermediate and the sole of the head intermediate
- the head intermediate body is sandwiched between a second mold that is in contact with the outer surface of the head, an internal pressure is applied to the head intermediate body via a bladder, and a press pressure is applied between the first mold and the second mold.
- a step of curing the cover material by heating while applying, An elastic body is arranged in a contact portion with the outer shell member of the second mold.
- the outer shell of the second molding die is used. Since the elastic body is arranged at the contact portion with the member, even if the metal outer shell member is different from the design dimension, the elastic body of the second mold is deformed according to the shape of the outer shell member, Equalizes the pressure applied to the head intermediate during molding. Therefore, the metal outer shell member and the fiber reinforced resin cover material are bonded under equalized pressure, so that the bonding state of the composite material can be improved.
- FIG. 1 is a cross-sectional view showing a golf club head molding apparatus according to an embodiment of the present invention.
- FIG. 2 is a plan view showing an example of a metal outer shell member used in the present invention.
- FIG. 3 is a cross-sectional view showing a conventional golf club head forming apparatus.
- FIG. 1 shows a golf club head molding apparatus that is also an embodiment of the present invention
- FIG. 2 shows an example of a metal outer shell member used in the present invention
- the molding apparatus of the present embodiment includes a lower mold 1 (first molding mold) and an upper mold 2 (second molding mold) that form a cavity that matches the shape of the head product.
- Lower mold 1 corresponds to the crown part
- upper mold 2 corresponds to the sole part.
- An elastic body 3 is disposed at a contact portion of the upper mold 2 with the golf club head.
- the pressure supply 4 is connected to a bladder 5 inserted in the golf club head.
- a metal outer shell member 11 having an opening 11a is prepared.
- the outer shell member 11 is formed in accordance with the shape of the face portion F, crown portion C, sole portion S, and hosel portion H of the golf club head to be obtained.
- a flange l ib is provided around the opening 11a.
- the golf club head can be more effectively lowered in the center of gravity. Further, by providing the flange l ib around the opening 11a, it is possible to secure a sufficient contact area of a cover material described later and increase its adhesive strength.
- the cover member 12 made of uncured fiber-reinforced resin is applied to the outer shell member 11 so as to cover the opening 11a to form the head intermediate body 13 (FIG. 1). reference).
- the bladder 5 is inserted into the head intermediate body 13 prior to the cover material 12 being attached.
- the outer shell member 11 is provided with a hole 11c for pulling out the connecting portion of the bladder 5.
- the outer surface of the crown portion C of the head intermediate body 13 is brought into contact with the lower mold 1, and the outer surface of the sole portion S of the head intermediate body 13 is brought into contact with the upper mold 2.
- the cover material 12 is cured by heating by a heating means (not shown).
- a golf club head having a hollow structure made of a composite material can be obtained.
- the elastic body 3 is disposed at the contact portion of the upper mold 2 with the outer shell member 11, so that a metal outer formed by forging or the like is used. Even when the shell member 11 has a different design dimension, the elastic body 3 disposed in the upper mold 2 is deformed according to the shape of the outer shell member 11 and is applied to the head intermediate body 13 during molding. Equalize the pressure. Therefore, the outer shell member 11 made of metal and the cover material 12 made of fiber reinforced resin are joined under equal pressure, so that the joining state of the composite material can be improved. it can.
- the internal pressure is gradually increased while maintaining the state in which the press pressure is always higher than the internal pressure as a method of applying the internal pressure and the press pressure. It is preferable. By gradually increasing the internal pressure, the resin flow becomes better, and the bonding state of the composite material can be further improved.
- the elastic body As a constituent material of the elastic body, it is preferable to use silicone rubber or heat-resistant hard rubber.
- the elastic body may be a solid body or a bladder that can be filled with gas.
- titanium alloy, aluminum alloy, stainless steel, or the like can be used as a constituent material of the outer shell member.
- the cover material is composed of a fiber reinforced fiber using a thermosetting resin such as epoxy resin as a matrix and carbon fiber as a reinforcing fiber. It is preferable to use fat.
- the present invention is suitable for manufacturing a wood type golf club head having a large head volume, but can be applied to both a wood type and an iron type as long as it is molded by an internal pressure molding method. It is. Further, in the above embodiment, the force of disposing the fiber reinforced resin cover material at one location of the golf club head In the present invention, it is also possible to arrange the cover material at 2 locations or more.
