Golf club head and method for manufacturing the same

Abstract

A golf club head and a method for manufacturing the same are provided. The golf club head includes a club head body and a striking face unit. The club head body includes a main body and a coupling portion extending from the main body, defining an opening, and having an end that is concaved toward the main body to form an engaging recess. The striking face unit has a connecting portion and covers the opening. The connecting portion is inserted into the engaging recess of the coupling portion and is connected to the club head body. The club head body is made of a first metal material and the connecting portion is made of a second metal material having a melting point higher than that of the first metal material.

What is claimed is: 
     
         1 . A golf club head, comprising:
 a club head body that includes a main body and a coupling portion, said coupling portion extending from said main body, defining an opening and having an end that is concaved toward said main body to form an engaging recess; and   a striking face unit that has a connecting portion and that covers said opening, said connecting portion being inserted into said engaging recess of said coupling portion and connected to said club head body,   wherein said club head body is made of a first metal material and said connecting portion of said striking face unit is made of a second metal material having a melting point higher than that of said first metal material.   
     
     
         2 . The golf club head as claimed in  claim 1 , wherein said connecting portion is formed with a plurality of through holes located within said engaging recess, said club head body further including a plurality of tenons which are disposed in said engaging recess, which respectively extend through and fittingly engage said through holes, and each of which has two ends connected to said coupling portion. 
     
     
         3 . The golf club head as claimed in  claim 2 , wherein said striking face unit includes a frame body that has said connecting portion, and a striking plate that is connected to said frame body and cooperates with said frame body to cover said opening. 
     
     
         4 . The golf club head as claimed in  claim 3 , wherein said frame body further includes a curved portion that is disposed between and interconnects said striking plate and said connecting portion. 
     
     
         5 . The golf club head as claimed in  claim 4 , wherein said curved portion is made of said second metal material. 
     
     
         6 . The golf club head as claimed in  claim 3 , wherein said main body of said club head body further defines a top opening, said golf club head further including a cover that is connected to said main body to cover said top opening. 
     
     
         7 . The golf club head as claimed in  claim 1 , wherein said first and second metal materials are respectively selected from the group consisting of stainless steel, maraging steel, titanium alloy, aluminum alloy and combinations thereof. 
     
     
         8 . The golf club head as claimed in  claim 3 , wherein said club head body is made of a stainless steel material and said frame body of said striking face unit is made of a titanium alloy material. 
     
     
         9 . The golf club head as claimed in  claim 1 , wherein said club head body is a casted club head body formed by a casting process. 
     
     
         10 . A method for manufacturing a golf club head, comprising the steps of:
 providing a frame body having a connecting portion formed with a plurality of through holes;   disposing the frame body into a mold formed with a cavity;   pouring a molten first metal material into the mold so that the molten first metal material fills the cavity and the through holes of the connecting portion; and   solidifying the molten first metal material to form a casted club head body that is connected to the connecting portion of the frame body.   
     
     
         11 . The method for manufacturing the golf club head as claimed in  claim 10 , wherein the frame body is made of a second metal material which has a melting point higher than that of the first metal material. 
     
     
         12 . The method for manufacturing the golf club head as claimed in  claim 10 , further comprising, after solidifying the molten first metal material to form a casted club head body, connecting a striking plate to the frame body to form a striking face unit. 
     
     
         13 . The method for manufacturing the golf club head as claimed in  claim 10 , further comprising connecting a striking plate to the frame body, in the disposing step, the striking plate is disposed into the mold along with the frame body.
