Model of a golf club head for molding

Abstract

A model of a golf club head for casting includes a body with an ankle. 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. Whereby, the casting pipe is integrally formed with the body, so a cost involved in making an investment mold is low. Because the quality of the connection between the casting pipes and the casting gate is reliable, the production yield of the golf club head is high. Furthermore, the overall size of the model of the golf club head is small, such that a quantity of a mold tree is larger than that of the convention mold tree. Therefore, the capacity of each of mold tree is high.

1 . A model of a golf club head for casting comprising: 
 a body ( 20 ) with an ankle ( 21 );    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 ).    
   
   
       2 . The 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 ).  
   
   
       3 . The 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 ).
