Coated and sintered structure of different materials and golf club head

The present invention relates to a coated and sintered structure of a different material, and more particularly to a golf club head having a coated and sintered structure of a different material.

Golf has gradually become one of the popular leisure sports. Due to the popularity of golf, golf equipment has gradually gained attention. Among the golf equipment, the most important first golf club, the goodness of a club will affect the stability of the ball and the state of the ball after the ball, and one of the important players in the club is related to the hitting result. The first position of the club head set at one end of the club, and the position of the center of gravity of the club head directly affects the effect of the swinging of the ball. If the position of the center of gravity is high, the swing is less stable when hitting the ball and it is easy to make the ball fly off the fairway; Conversely, if the center of gravity is low, the stability of the swing is better, and the easier it is to control the direction of the ball after the shot.

Announcement No. I260991 "The weight of the golf club head" invention patent case, and the publication of the No. I1234474 "replaceable golf club head weight structure" invention patent case, both cases are at the sole of the club head The counterweight is placed on the side to reduce the center of gravity of the golf club head. However, the above-mentioned weights are combined with the screw seat at the bottom of the club head, that is, the club head and the weight screw of the screw seat are separately manufactured, and then the weight screw is added. When the screw is screwed onto the screw seat, the machining process is cumbersome, which leads to an increase in cost.

Therefore, there is a need to provide a golf club head that solves the aforementioned problems.

One of the novels of the present invention is to reduce the center of gravity of the golf club head by coating the sintered structure of the foreign material.

In order to achieve the above object, the present invention provides a coated and sintered structure of a different material, comprising: a first material, which is a metal powder press molding or a metal powder a second injection material; and a second material comprising a plate portion and a hollow column, the hollow column being integrally formed with the plate portion, the hollow column penetrating the plate portion, the hollow column The height is greater than the height of the plate portion, wherein the first material has a specific gravity greater than the specific gravity of the second material, the first material is located in the hollow column of the second material, and the second material is injection molded by a metal powder. The process is coated to sinter the first material.

The present invention further provides a golf club head comprising: the novel coated sintered structure and a club head body. The plate portion of the second material of the overclad structure includes a first weld face. The club head body includes a second welding surface that is welded to the first welding surface.

Figure 9 is a cross-sectional view showing the combination of the golf club head of the second embodiment of the present invention.

The above and other objects, features, and advantages of the present invention will become more apparent from the accompanying drawings.

Referring to Figures 1 and 2, there is shown a coated sintered structure 100 of a different material of the first embodiment of the present invention. The coated sintered structure 100 of the foreign material can be applied to a golf club head. The coated sintered structure 100 of the foreign material includes a first material 110 and a second material 120. The first material 110 can be a metal powder press molding or a metal powder injection molding material. The second material 120 includes a plate portion 124 and a hollow column 122. The hollow column 122 is integrally formed with the plate portion 124. The hollow column 122 extends through the plate portion 124. The height of the hollow column 122 is greater than the plate. The height of the shape 124. The specific gravity of the first material 110 is greater than the specific gravity of the second material 120. The first material 110 is located in the hollow column 122 of the second material 120, and the second material 120 is coated by a metal powder injection molding process. The first material 110 is sintered.

The metal powder press forming (PM) process is a processing method in which various products are produced by pressing and sintering using metal powder as a raw material. The metal powder press forming (PM) technique consists of three main steps. First, the main constituent material is granulated into a fine particle powder. Then, the powder is filled into a molding die, and a certain pressure is applied to first form a green body having a desired part shape and size. Finally, the green body is sintered at a high temperature to produce a metal part.

Metal Injection Molding (MIM) process uses metal powder and binder to prepare injection molding blanks through mixing, kneading and granulation. It is formed into a wax film through high-precision special mold and then dewaxed. A metal part is manufactured by a process such as sintering.

In this embodiment, referring again to FIG. 2, an A fitting is prepared, which may be a metal powder press molding or a metal powder injection molding first material 110. The first material 110 is not limited to the material of the material. For example, the first material 110 is a tungsten and nickel material, and mainly has a weighting effect, and can produce a low center of gravity club head design. The first material 110 can also be selected from other materials, such as selected from the group consisting of nickel, chromium, manganese, copper, titanium, stainless steel, carbon steel, or combinations of the foregoing. First material 110 The outer shape is not limited to a circular column, and can also be made into a polygonal column or a multi-curved column, so that the accessory has a more aesthetic design.

A B fitting is prepared, which is a second material 120. In detail, the second material 120 is a mixture of metal powder (titanium alloy or stainless steel material), plastic ester and wax, and the metal powder may be selected from other materials, for example, selected from the group consisting of nickel, chromium, manganese, copper, titanium, and stainless steel. Carbon steel or a combination of the above materials, after being mixed, kneaded and granulated, is placed in a molding machine to form a billet. The blank is injected into a pre-designed cavity, formed into a wax film through a high-precision special mold, and then dewaxed to become a green embryo. The second material 120 having a green embryo includes a plate portion 124 and a hollow column 122. The hollow column 122 is integrally formed with the plate portion 124, and the hollow column 122 extends through the plate portion 124.
