Method for producing golf club head and golf club head structure

Abstract

The process of producing golf club head includes the following steps: 1. making the lower metal member of integrated driving plane and club bottom; 2. prefabricating one die-casting die for integrated club side and cover; 3. fixing the lower metal member inside the die-casting die; 4. pouring metal liquid for die casting; and 5. de-molding to obtain the golf club head. Thus made golf club head is one hollow structure including one lower metal member and one upper metal member combined through die casting.

Description

technical field [0001] The invention relates to a manufacturing method and structure of a golf club head, in particular to a manufacturing method and structure of a golf club head which is directly die-cast from two metal components with different properties, has a simple structure, and has high ball-hitting elasticity. Background technique [0002] Golf has gradually become a popular sports and leisure activity in the recent society, and due to the popularization of golf, golf equipment has gradually been paid attention to. Among the golf equipment, the most important golf club is the most important one. The quality of a club is related to the stability of the ball when hitting the ball and the flight state of the ball after hitting the ball. The worst result is the club head at the bottom of the club. [0003] The structure of the existing club head includes a hollow club head body and a panel. When manufacturing the club head, the manufacturer mostly uses the precision c...

Problems solved by technology

However, this combination method has gaps due to the combination of the club head panel setting hole and the ball striking panel, and hydrogen welding is generally used for welding; while the required temperature of hydrogen welding is relatively high, but the weld bead is relatively shallow and The heat source is scattered and the strength is weak. Compared with ionized gas PLASMA welding or laser welding, the temperature is lower, the weld bead is deep, the strength is good, and the heat source is concentrated. Compared with the advantages, the effect is not ideal. In addition, hydrogen welding Solder must be injected all the time, which is more likely to cause the solder to flow into the club head, resulting in uneven weight of the club head and displacement of the center of gravity, so that the club head cannot get the proper hitting stability when hitting the ball; however The manufacturing of existing club heads is mostly done by precision casting. During the manufacturing process, some parts will be deformed and cause gaps.

[0004] The novel golf club head that uses at present also has multiple, as the patent information that Chinese patent application number is 200510024133.3, discloses a kind of golf club head that adopts and comprises hitting surface, club head sole, club head side, ball cover and club head. The golf club head with split welded structure of the head tube is mostly made of a single metal such as zinc, aluminum, titanium or stainless steel. The structure is relatively complicated, and the manufacturing and processing costs are high. Its elasticity is often weak, which cannot meet the requirements of making the ball fly farther and land more accurately, and because the club head is welded separately, cracks are prone to occur in various parts, which affects the service life of the club head
