Golf club head, weight-balancing block of golf club head and preparation method of weight-balancing block

Abstract

The invention provides a golf club head. The golf club head comprises a club head and a weight-balancing block, wherein the club head is provided with a bonding part; the weight-balancing block is detachably contained in the bonding part and comprises an elastic part and a colored layer; the colored layer is bonded on the surface of the elastic part; and the elastic part is formed by a polymer material and metal powder. Therefore, the weight-balancing block can not only improve the hitting efficiency by adopting the elastic part to achieve better shock absorption and weight balance functions but also utilize the colored layer to improve the weight-balancing identifiability and appearance variability of the golf club head.

Description

technical field [0001] The present invention relates to a golf club head with a counterweight, in particular to a golf club head combined with a counterweight with recognizable appearance and functions of counterweight and shock damping. Background technique [0002] Please refer to figure 1 As shown, as Japanese patent No. 4400196 discloses a golf iron club head 9, a concave portion 92 is provided behind the striking surface 91 of the golf iron club head 9, and a fiber-reinforced synthetic resin body 93 is filled in the concave portion 92. Several rib grooves are provided between the surface 91 and the fiber-reinforced synthetic resin body 93, and the several rib grooves are used for adding a resin layer 94 of high specific gravity metal powder, and the resin layer 94 can be selected as a thermoplastic elastomer. In this way, the shock absorbing properties of the resin layer 94 can be used to improve the shock generated by the golf iron head 9 , and the high specific gravi...

Problems solved by technology

However, in the process of mixing and dyeing, it is easy to affect the mixing uniformity of metal powder and polymer materials in the weight block due to the addition of dyes, so that the specific gravity distribution of the adjustment element 82 is uneven, resulting in the adjustment element The damping effect of 82 is unstable, and even affects the stability of the counterweight of the adjustment element 82, so that the quality of the adjustment element 82 is not good enough to provide an accurate counterweight effect of the golf club head 8; moreover, it is more likely because The process of adding dye to the adjustment element 82 changes the original setting specific gravity of the adjustment element 82, and even reduces the mechanical properties such as elasticity and strength of the adjustment element 82, so that the operator must spend extra process and time to adjust the adjustment element 82 again. Adjust the ratio between the components of the component 82

In this way, not only can the adjusting element 82 not have better counterweight and damping functions, but even because the overall quality of the adjusting element 82 is not good, it is impossible to effectively use the adjusting element 82 to control the overall center of gravity of the golf club head 8. It is more likely to increase the time required due to the cumbersome manufacturing process of the adjustment element 82
