Model of a golf club head for molding

Abstract

A model of a golf club head for casting includes a body having an upper plate with a small thickness. An ankle is formed at an end of the upper plate and at least one rib formed on the upper plate. A casting gate is formed beside the ankle. A casting pipe extends from the casting gate and around the body. Multiple ducts are connected between the casting pipe and the body. The at least one rib is connected to the ducts. Whereby, a duration of molten alloy to form the upper plate is short because the flow velocity of the alloy is quick. At the same time, the density of the upper plate is increased to reinforce its strength and improve its strike sound. Moreover, the overall size of the golf club head is small, such that a mold tree can include more investment molds to increase its capacity.

1 . A model of a golf club head for casting comprising: 
 a body ( 20 ) having an upper plate ( 22 ) with a small thickness, an ankle ( 21 ) formed at an end of the upper plate ( 22 ), and at least one rib ( 24 ) formed on the upper plate ( 22 );    a casting gate ( 10 ) formed beside the ankle ( 21 );    a casting pipe ( 30 ) extending from the casting gate ( 10 ) and around the body ( 20 ); and    multiple ducts ( 31 ) connected between the casting pipe ( 30 ) and the body ( 20 ), and the at least one rib ( 24 ) connected to the ducts ( 31 ).    
   
   
       2 . A model of a golf club head for casting as claimed in  claim 1 , wherein the rib ( 24 ) has two protrusions ( 26 ) respectively formed at two sides of the rib ( 24 ), two first datum surfaces ( 25 ) lower than the protrusions ( 26 ) are formed between the rib ( 24 ) and the protrusions ( 26 ), two second datum surfaces ( 27 ) lower than the protrusions ( 26 ) are formed outside the protrusions ( 26 ).  
   
   
       3 . A model of a golf club head for casting as claimed in  claim 1 , wherein the ducts ( 31 ) are located beneath a split line of the body ( 20 ).  
   
   
       4 . A model of a golf club head for casting as claimed in  claim 1 , wherein the casting pipe ( 30 ) has a cold liquid accumulation area ( 32 ) formed at a distal end of the casting pipe ( 30 ).  
   
   
       5 . A model of a golf club head for casting as claimed in  claim 1 , wherein the body ( 20 ) has three ribs ( 24 ) that together form a single Y shape.  
   
   
       6 . A model of a golf club head for casting as claimed in  claim 1 , wherein the body ( 20   b ) has only one rib ( 24   b ).  
   
   
       7 . A model of a golf club head for casting as claimed in  claim 1 , wherein the body ( 20   d ) has three parallel ribs ( 24   d ).  
   
   
       8 . A model of a golf club head for casting as claimed in  claim 1 , wherein the body ( 20   a ) has two arcuate ribs ( 24   a ) symmetric to each other.  
   
   
       9 . A model of a golf club head for casting as claimed in  claim 1 , wherein the body ( 20   c ) has two ribs ( 24   c ) intersected to each other.
