Through the positioning hole 22, the positioning portion 32, and the positioning pin tip 33, the stable setting of the sand core 20 is located in the cavity 31 of the mold 30. μ, please refer to Figs. 3 to 5, 7 and 8, the second step of the golf club head and the manufacturing method of the present invention is to inject mash into the mold 30 to make a soil mold! 0 ', and the The wax mold 10 'partially covers the sand core 20. After the sand core 20 is positioned in the mold cavity 31, the present invention injects ^ liquid into the mold cavity 31 through the pouring port [not shown] of the mold 30. After the wax liquid is cured and formed, a butterfly mold 10 ′ can be formed. The shape of the wax mold 10 is the same as that of the head body. It also includes a ball striking surface 11, a weight 12, and a Collar 13, and a long notch 14 ,. Next, the wax mold 10 is demolded, and the positioning pin 33 of the mold 30 is taken out, so that the sand core 20 is released from the mold 30 at the same time. At this time, the sand core 20 is temporarily partially covered with the wax mold 10, and is correspondingly located on the long slot 14 ′. Referring to Figures 3 to 5, 8 and 9, the third step of the golf club head and bean manufacturing method of the present invention is a sand shell mold 40 made of wax mold 10 and sand core 20 soaking. When the wax mold 10 is made, and the sand core is partially coated 20, the present invention immerses the integrated wax mold 10 and the sand core 20 into a gypsum liquid or other viscous molding materials at the same time, so that the gypsum is stained. It is adhered to the wax mold 丨 0 and the outer side of the sand core 20, thereby forming a sand setting branch 40. Next, the sand shell mold 40 is subjected to an over-drying or drying process to completely solidify the sand shell mold 40. Referring to Figures 3 to 5, 9 and 10, the fourth step of the golf club head and its manufacturing method of the present invention is to remove the wax mold 10 in the sand shell mold 40 by heating. After the molding 40 is cured and formed, the present invention then heats the sand shell mold 40 to dissolve the pull-in wax branch 10 into a wax liquid, and flows out from the pouring f of the sand shell mold 40.] .

At this time, the sand core 20 is still bonded to the sand shell mold 40 by the top ear 21 and the positioning hole 22, so that the sand core 20 can be stably suspended and positioned in the mold cavity 41. Referring to FIGS. 3 to 5 and 10, the fifth step of the golf club head and the manufacturing method of the present invention is to inject the molten metal into the sand shell mold 40. The invention selects and uses an appropriate metal or alloy material according to product requirements. Next, the metal or alloy is completely melted and liquefied by heating, and injected into the sand shell mold 40. After the metal or alloy is cooled and solidified, the head body 10 can be obtained by the present invention. Please refer to Figures 3 to 5 and Figures 11 and 12.

The root, " 卩 1 〇3 forms a shallow groove 15 within the peripheral edge [wax mold 10, corresponding to the formation of shallow groove 15] 4 The shallow groove 15 is preferably connected to the long slot 14, the shallow groove 1 5 And the long slot 14 are arranged on the periphery of the back surface of the striking surface n in common, and at the same time, the wearing surface size of the connecting position between the striking surface 11 and the head body 10 is reduced.
發明可進一步提升該擊球面11之彈性變形能力及其遠距離 擊球能力。 雖然本發明已以較佳實施例揭示，然其並非用以限定本 發明丄任何熟習此技藝者，在不脫離本發明之精神和範圍 内，s可作各種更動與修改，因此本發明之保護範冬 後附之申請專利範圍所界定者為準。 曰The invention can further improve the elastic deformation ability of the hitting surface 11 and its long-distance hitting ability. Although the present invention has been disclosed in a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection of the present invention Fan Dong's attached patent application scope shall prevail. Say
