Definitions

  • the present invention relates to a golf club head, and more particularly to a model of a golf club head for molding.
  • an upper plate of the golf club head may be made as thin as possible.
  • the minimum thickness of the upper plate by molding is about 0.9 mm.
  • a further thin upper plate is assembled on a body of the golf club head by laser welding or explosive welding.
  • the upper plate is eroded by strong acid to become thinner.
  • costs involved in laser welding or explosive welding are high, and using strong acid will cause pollution.
  • all three methods require skilled personnel that are exposed to hazardous work practices.
  • a rough blank of the golf club head ( 60 ) has an upper plate ( 61 ) and an ankle ( 64 ) formed at an end of the upper plate ( 61 ).
  • the upper plate ( 61 ) has multiple process areas ( 62 ) and multiple ribs ( 63 ) to divide the process areas ( 62 ).
  • a major casting gate ( 70 ) is formed beside the ankle ( 62 ).
  • Three casting pipes ( 71 , 72 , 73 ) extend from the major casting gate ( 70 ), and respectively are connected to three secondary casting gates ( 74 , 75 , 76 ) formed on the upper plate ( 61 ).
  • the ribs ( 63 ) are ground to make a thin upper plate ( 62 ).
  • the major casting gate ( 70 ), casting pipes ( 71 , 72 , 73 ), and secondary casting gates ( 74 , 75 , 76 ) are block, strips and slices separately molded in respective molding dies.
  • investment molds of the casting pipes ( 71 A, 72 A, 73 A) must be made and manually connected to investment molds of the secondary casting gates ( 74 A, 75 A, 76 A). Because the quality of the connection between these investment molds is unreliable, the production yield of the golf club head is low.
  • contraction cavities may be formed in a wall under intersections of the ribs ( 63 ), so the strength of the upper plate ( 61 ) is low and the head will generate a sour-sound in striking of a golf ball.
  • the quantity of the ribs ( 63 ) is large and a grinding time is long.
  • multiple molds are connected together to form a molding tree for molding.
  • the investment molds of the casting pipes ( 71 A, 72 A, 73 A) occupy a large space such that a quantity of mold dies in one mold tree is limited, so the capacity of each of mold tree is limited.
  • the invention provides a model of a golf club head for molding to mitigate or obviate the aforementioned problems.
  • the main objective of the present invention is to provide a model of a golf club head which can be formed with a thin upper plate and is easy to be molded.
  • FIG. 1 is a perspective view of a first embodiment of a model of a golf club head for molding in accordance with the present invention
  • FIG. 2 is a top view of FIG. 1 ;
  • FIG. 3 is a bottom view of FIG. 1 ;
  • FIG. 4 is a cross sectional view of FIG. 1 ;
  • FIG. 5 is an enlarged partially cross sectional view of the first embodiment
  • FIG. 6 is a perspective view of a second embodiment of the present invention.
  • FIG. 7 is a perspective view of a third embodiment of the present invention.
  • FIG. 8 is a perspective view of a fourth embodiment of the present invention.
  • FIG. 9 is a perspective view of a fifth embodiment of the present invention.
  • FIG. 10 is a perspective view of a conventional golf club head
  • FIG. 11 is a bottom view of the conventional golf club head.
  • FIG. 12 is an exploded perspective view of an investment mold of the conventional golf club head.
  • a model of a golf club head for molding in accordance with the present invention has a body ( 20 ).
  • the body ( 20 ) has an upper plate ( 22 ) with a small thickness.
  • An ankle ( 21 ) is formed at an end of the upper plate ( 22 ).
  • a casting gate ( 10 ), which is a block formed during molding, is formed beside the ankle ( 21 ).
  • the upper plate ( 22 ) has at least one (three to form as a Y-shape in this embodiment) rib ( 24 ) defined on the upper plate ( 22 ) to reinforce a strength of an investment mold in conformity with this model.
  • the investment mold is fully supported by the rib ( 24 ) and is prevented from being deformed during dipping.
  • each of the ribs ( 24 ) has two protrusions ( 26 ) respectively formed at two sides thereof.
  • Two first datum planes ( 25 ) are respectively formed between the rib ( 24 ) and the two protrusions ( 26 ), and two second datum planes ( 27 ) are formed outside the two protrusions ( 26 ).
  • the ducts ( 31 ) are located beneath a split line of the body ( 20 ).
  • a cold liquid accumulation area ( 32 ) is formed at a distal end of the casting pipe ( 30 ).
  • the ribs ( 24 ) are respectively connected to the ducts ( 31 ).
  • the investment mold is manufactured according to the model of the golf club head. Multiple mold dies are connected together to construct a mold tree.
  • molten alloy is poured from an investment mold of the casting gate and quickly flows through investment molds of the casting pipe, ducts and ribs to form the body ( 20 ). Cooling alloy accumulates in the cold liquid accumulation area ( 32 ) to prevent the casting gate ( 10 ) being blocked.
  • the casting gate ( 10 ) and ducts ( 31 ) are cut off from the body ( 20 ). Then, the rib ( 24 ) is first ground by coarse rubbers to match a height of the protrusions ( 26 ). Afterwards, the remaindering ribs ( 24 ) and the protrusions ( 26 ) are all ground together by fine rubbers according to the first and second datum planes ( 25 , 27 ) to finish a glazed surface. Using the protrusions ( 26 ) and two-step grinding can prevent the body ( 20 ) from being ground excessively and so waste products are prevented.
  • the body ( 20 a ) has two arcuate ribs ( 24 a ) symmetric to each other.
  • the body ( 20 b ) has only one rib ( 24 b ) extending through the upper plate ( 22 b ).
  • the body ( 20 c ) has two ribs ( 24 c ) intersecting each other.
  • the body ( 20 d ) has three parallel ribs ( 24 d ).
  • the duration of molten alloy injection to form the upper plate is short because the ribs ( 24 ) enable acceleration of the flow velocity of the molten alloy.
  • the density of the upper plate ( 22 ) is increased to reinforce its strength and improve its strike sound.
  • the overall size of the model of the golf club head is small, whereby a mold tree can include more investment molds. Therefore, the capacity of each of mold tree is high.
