Description

Golf club head

The present invention relates to a golf equipment, in particular to a golf club head.

Referring to Figure 1, the traditional golf club head 1 often uses metal as the main material, but metal has the disadvantage of high density and heavier weight. Therefore, composite materials with high strength but low density are gradually being used to replace metal. To improve functionality, for example, the top cover 11 of the golf club head 1 made of carbon fiber board is now a common mainstream design. However, the appearance of the carbon fiber board is limited, so parts such as the bottom of the ball head still need to be made of metal. , But there are also restrictions on metal molding. For example, the limitation of casting wax shrinkage or casting shrinkage will cause the finished product to differ from the design drawing. In addition, when you need to add weights and other accessories 12, you need to glue or lock The way of combining the metal parts 13 makes the arrangement of the fittings 12 still limited by the metal parts 13. The above-mentioned situations will lead to the problem of a higher amount of the metal parts 13 and a higher cost.

Therefore, the object of the present invention is to provide a golf club head that can reduce the amount of metal parts and increase the application flexibility.

Thus, the golf club head of the present invention includes a metal piece, a composite body connected to the metal piece and cooperated with the metal piece to define at least one opening, at least one accessory fixed by the composite body in a shot-packing manner, and At least one top cover made of carbon fiber board and closing the at least one opening. The composite body is made by wrapping at least one carbon fiber board in a plastic through-shooting method.

The effect of the present invention is that the at least one carbon fiber board and the at least one accessory are integrally formed through a shot-packing method, the at least one carbon fiber board can provide a high-strength structure, and the plastic has good fluidity, and the shape limit that can be formed is lower than that of metal , There is no limitation of casting wax shrinkage and casting shrinkage. The finished product has a high degree of agreement with the design drawings. Therefore, the composite body can extend the at least one carbon fiber board to the bottom of the entire ball head (if necessary, use multiple carbon fiber boards to increase Area) to greatly reduce the amount of metal and increase design flexibility.
