Golf head device

Abstract

The invention discloses a golf head device, which comprises a golf head blank, an outer circular runner, a plurality of runner assisting sprue gates and a main sprue gate, wherein the golf head blankis provided with a parting line; the outer circular runner is arranged in a mode of extending along the surface of the outer side of the parting line of the golf head blank; the runner assisting spruegates are connected between the outer circular runner and the parting line of the golf head blank; and the main sprue gate is arranged at one end of the outer circular runner, and a spacing is formedbetween the main sprue gate and the golf head blank. The golf head device provided by the invention simultaneously has the advantages of improving the yield of the golf head blank, shortening the cutting time, reducing polishing cost, increasing the gravity center of a golf head and the freedom degree of dimension design and the like.

Description

technical field [0001] The invention relates to a golf head device, in particular to a golf head device with low follow-up processing cost and improved yield of the finished ball head. Background technique [0002] Golf has become one of quite popular leisure sports. Due to the popularity of golf, golf equipment has also received considerable attention. Among the golf equipment, the most important thing is the golf club. The quality of a club will affect the stability of the ball when hitting the ball and the state of the ball flying after hitting the ball. Push the head set on one end of the club. [0003] The traditional hollow golf head, taking No. 1 driver as an example, its material ranges from stainless steel to titanium alloy metal, which is preferred by most golfers. So far, major manufacturers are working hard to develop how to improve it. The quality of the golf head and the increase in production capacity, thereby reducing costs and improving competitiveness; h...

Problems solved by technology

[0007] 1. Since the aforementioned main sprue 70 directly connected with the golf head blank 60 must not only have a certain area to support the tree formation on the tree frame, but also must have a certain thickness to be connected with the outer ring runner 80 as a Only one body can be cast into the golf head blank 60, and the upper cover of the golf head blank 60 is designed to have a thinner thickness near the neck 61. The difference between thermal expansion and contraction between the upper cover 62 near the neck 61 and the main sprue 70 will cause thermal cracks to occur on the upper cover 62 of the golf head blank 60 near the neck 61, resulting in golf head blanks 60% increase in defective rate

[0008] 2. After casting the golf head blank 60, since the main sprue 70 directly connected with the golf head blank 60 has a certain area, it needs to cut a large area and for a long time, except for increasing the cutting gas. In addition to the cost, the large amount of heat generated during cutting will reduce the strength of the golf head blank 60 around the main sprue 70, so the design has to be done by adding the golf head blank 60 around the main sprue 70. The thickness of the golf ball can increase the strength, but it will reduce the design freedom of the center of gravity and size of the golf head and increase the manufacturing cost

[0009] 3. After cutting the main sprue 70, it is necessary to further use an abrasive belt to remove the part of the main sprue 70 remaining on the golf head blank 60 and to polish the golf head blank 60. The lighting time and the required manpower cannot be effectively reduced, thus increasing the cost
