Problems solved by technology
[0005] As far as the above-mentioned existing ball head is concerned, its empty bridge auxiliary runners 71, 72, 73 are as follows: Figure 12 The auxiliary gates 74, 75, and 76 of the wax mold of the ball head must be hot-melted and connected to the auxiliary gates 74, 75, and 76 of the ball head wax mold in a manual way. After the connection, the structural quality of each ball head connection cannot be unified and standardized, resulting in good products of casting molding. After casting, the interlaced wall thickness of the thin upper cover 61 factor bar convex part 63 will cause a large internal shrinkage cavity, which will affect the wall thickness strength of the golf head and the sound produced when hitting the ball. , while the empty bridge auxiliary runners 71, 72, 73 of the ball head and the several convex parts 63 of the thin upper cover 61 will lengthen the grinding time due to the large grinding area. In addition, when the wax mold of the ball head is assembled During the program, the space occupied by the empty bridge auxiliary sprues 71, 72, 73 of the wax mold increases, which affects the number of ball heads in each tree group, so the number of ball heads in the capacity group tree for each casting is jointly affected. limit, it is necessary to improve

Embodiment Construction
[0043] The present invention is a kind of golf head device that can reduce the thickness of the head cover, such as figure 1 Figure 4 Shown in, the following will further illustrate the preferred embodiment with the accompanying drawings.
[0044] Such as Figure 1-Figure 4 As shown, there is a main sprue 10, and the main sprue 10 is arranged on the lower end of the neck 21 provided on the golf head 20; the main innovative features of the present invention are:
[0045] For the thin loam cake 22 with larger area, at least one (can be three) loam cake auxiliary flow channels 24 such as ( Figure 5 shown in ), its main function can produce the strength of the auxiliary wax pattern, fully support the overall structure of the wax pattern after molding, in addition to fully preventing the deformation of the wax pattern when it is soaked in slurry, adjacent to the two sides of the auxiliary flow channel 24 of the upper cover Formed respectively with polishing datum planes 25,27...

An apparatus for manufacturing a golf club head with thickness-decreased top cover has more than one auxiliary flowing channel for top cover, and an external annual flowing channel with several pouring gates for shortening the casting time. The finished golf club head features its improved density, strength and hit sound.
Description
technical field [0001] The present invention relates to a device for manufacturing a golf head with a reduced thickness of the cap, mainly to manufacture a golf head with a thin cap. Background technique [0002] Golf has been a popular leisure sport at present, and along with the popularization of golf, golf utensils are also gradually paid attention to. Among the golf equipment, the most important thing is to push the club. The quality of the club will affect the stability of the ball when hitting the ball and the flight condition of the ball after hitting the ball. Among the clubs, the most important thing related to the result of the ball is the First push the ball head. [0003] The traditional one-piece golf head, whether it is made of stainless steel metal or titanium alloy metal that most golfers like, so far, all major manufacturers are working hard to develop how to improve the center of gravity of the golf head and expand the hitting range. For the required effe...
