Embodiment

[0032] Example: see Figure 1 ~ Figure 4 , an improved manufacturing method for an integrated golf club head provided in this embodiment, comprising the following steps:

[0033] (1) Prefabricate an inner sleeve 3 with the same shape as the inner cavity of the golf club head 1 and a size approximately equal to the inner cavity of the golf club head by using a metal material with a higher melting point; and the inner sleeve 3 is provided with an opening ;

[0034] (2) Prepare the granular inner sleeve filler 4, put it into the inner cavity 6 of the inner sleeve 3 through the opening, and make it full and fill the inner sleeve cavity 6 to form a solid ;

[0035] (3) Prefabricate a club head die-casting mold 11;

[0036] (4) The inner sleeve 3 is physically fixed in the die-casting mold 11;

[0037] (5) Pouring metal liquid with a melting point not higher than the melting point of the metal material of the inner sleeve 3 into the mold 11 for die-casting; There is a cavity 14...

Abstract

The invention discloses a manufacturing method for improving an integral golf club head, which includes the following steps: (1) precasting an internal sleeve, the outer contour of which is the same with the shape of an inner cavity of the golf club head, and at least one opening is arranged in the internal sleeve; (2) preparing granular filling materials for the internal sleeve and placing the filling materials into the inner cavity of the internal sleeve through the opening; (3) precasting a die-casting die of the club head; (4) fixing the entity of the internal sleeve in the die-casting die; (5) casting metal liquid, the casting melting point of which is not higher than the melting point of the metal material of the internal sleeve, into the die, and the die is cast and formed; (6) preparing a club head embryo which consists of a shell layer, an internal sleeve layer and filling materials after die de-molding; (7) drilling a bore hole which permeates the shell layer and the internal sleeve layer on the embryo club head; and (8) manufacturing the golf club head by arranging the opening of the bore hole downward to cause the filling materials to flow out automatically from the bore hole. The method also discloses a product made by adopting the method.

Description

technical field [0001] The invention relates to a club head manufacturing technology, in particular to an improved manufacturing method and product of an integrated golf club head with simple manufacturing process, high production efficiency and stable quality. Background technique [0002] In the prior art, the golf club head mostly adopts a split-type manufacturing process, that is, the hitting surface, the club head sole, the club head side, the ball cap and the club head tube are manufactured separately, and then welded to each other to form. The main disadvantage of this technology is that there are many manufacturing processes and high cost. The surface treatment and baking of the finished golf club head require additional processes such as seam repair and soil repair, and weld seams are prone to appear during use. Cracking phenomenon, resulting in damage to the club head and generally shorter lifespan. In order to improve the above-mentioned shortcomings of the prior...
