DETAILED DESCRIPTION OF THE EMBODIMENTS

[0055] The technical solution of an amorphous alloy golf club head according to the present invention will be further described below in detail with reference to the accompanying drawings and specific embodiments.

[0056] As shown in FIGS. 1 and 2, the present invention provides an amorphous alloy golf club head integrally casted from an amorphous metal material, comprising:

[0057] a neck configured for combination with a club;

[0058] a hitting panel connected to the bottom of the neck;

[0059] a peripheral wall located on a rear surface of the hitting panel, the peripheral wall forming a rear concave cavity with the hitting panel, wherein

[0060] the peripheral wall comprises a thin-walled portion surrounding an upper edge and a side edge of the rear surface of the hitting panel, and a thick-walled portion surrounding the bottom of the rear surface of the hitting panel;

[0061] a cushion block embedded in the thick-walled portion to reduce the casting thickness of the thick-walled portion, and provided with a plurality of pillars thereon, wherein

[0062] one end of each pillar is fixedly connected to the cushion block body, and the other end of the pillar has an exposed surface or exposed section not covered by the peripheral wall; and

[0063] an adjusting member matingly connected to the pillar and configured to adjust the tightness between the embedded cushion block and the peripheral wall.

[0064] In order to reduce the casting thickness of the thick-walled portion and reduce the risk of crystallization in preparation of the large-size amorphous alloy golf club heads due to the slower cooling rate, the present invention embeds the cushion block with pillars in the cavity.

[0065] As a preferred embodiment of the technical solution of the present invention, the wall thickness of the thick-walled portion is 10 mm to 30 mm.

[0066] As a preferred embodiment of the technical solution of the present invention, the hitting panel is an equal-thickness panel having a thickness of 1.5 mm to 5 mm.

[0067] As a preferred embodiment of the technical solution of the present invention, the wall thickness of the thin-walled portion is 1.5 mm to 6 mm.

Embodiment 1

[0068] As shown in FIG. 4, the present invention provides an amorphous alloy golf club head integrally casted from an amorphous metal material, comprising:

[0069] a neck configured for combination with a club;

[0070] a hitting panel connected to the bottom of the neck;

[0071] a peripheral wall located on a rear surface of the hitting panel, the peripheral wall forming a rear concave cavity with the hitting panel, wherein

[0072] the peripheral wall comprises a thin-walled portion surrounding an upper edge and a side edge of the rear surface of the hitting panel, and a thick-walled portion surrounding the bottom of the rear surface of the hitting panel; and

[0073] a cushion block embedded in the thick-walled portion to reduce the casting thickness of the thick-walled portion, and provided with three pillars thereon, wherein

[0074] one end of each pillar is fixedly connected to the cushion block body, and the other end of the pillar has an exposed surface not covered by the peripheral wall. The pillar is disposed inside the thick-walled portion and has an exposed surface. The pillar has an internal thread. The adjusting member is a bolt. The bolt is matingly connected to the internal thread on the pillar by means of the exposed surface. Providing a bolt on the pillar subjected to internal thread treatment can also adjust the tightness of the embedded cushion block and the outer amorphous alloy.

Embodiment 2

[0075] As shown in FIG. 3, the present invention provides an amorphous alloy golf club head integrally casted from an amorphous metal material, comprising:

[0076] a neck configured for combination with a club;

[0077] a hitting panel connected to the bottom of the neck;

[0078] a peripheral wall located on a rear surface of the hitting panel, the peripheral wall forming a rear concave cavity with the hitting panel, wherein

[0079] the peripheral wall comprises a thin-walled portion surrounding an upper edge and a side edge of the rear surface of the hitting panel, and a thick-walled portion surrounding the bottom of the rear surface of the hitting panel; and

[0082] Further, the counterweight of the amorphous alloy golf club head of the present invention can be realized by changing the bolt or nut connected to the pillar, or by embedding cushion blocks with different types of materials. Cushion blocks of different weights can be obtained by selecting and replacing the cushion blocks of different materials, so that the counterweight can be performed according to the counterweight requirements. The cushion block can be made of a metal material such as an aluminum alloy, a titanium alloy, a stainless steel, and a copper alloy.

[0083] The die-casting mold of the amorphous alloy golf club head according to the present invention is composed of a moving mold plate, a moving mold core, a fixed mold core, and a fixed mold plate. The moving mold core and the fixed mold core form a cavity when mold closing is performed on the moving mold plate and the fixed mold plate.

[0084] The metal block is embedded in the mold core by means of the pillar to ensure that the embedded metal block can be accurately positioned when mold closing is performed.

[0085] A sprue bushing and a sprue spreader are disposed on the fixed mold plate, and are connected to a die-casting machine and the cavity, respectively.

[0086] The alloy melt obtained through induction melting enters the sprue bushing under pressure, and enters the cavity through the action of the sprue spreader to obtain the club head product.

[0087] Finally, it should be noted that the embodiments above are only intended to illustrate the technical solution of the present invention, and are not limiting. Although the present invention is described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications to specific embodiments of the present invention or equivalent replacement of some technical features can still be made, and these modifications should be covered by the scope of the technical solution claimed by the present invention, without departing from the spirit of the technical solution of the present invention.
