Description
- 1. Field of the Invention
- The present invention generally relates to a method for manufacturing a cup-shaped striking faceplate of a wood golf club head and, more particularly, to a method for manufacturing a cup-shaped striking faceplate of a wood golf club head made of carbon fiber.
- 2. Description of the Related Art
- In the art field of golf, for a better control of the golf ball trajectory and landing spot, a counter weight is generally disposed in a golf club head in accordance with the user's preference to lower the gravity center of the golf club, thus enlarging the sweet spot of the golf club head. Consequently, even if the hitting spot of the golf ball is apart from the center of the sweet spot, as long as the hitting spot is within the sweet spot, the trajectory of the ball may not significantly vary and the golf ball may land within the target area.
- However, the counter weight disposed in the golf club head results in total weight increasing of the golf club, and therefore places a further burden to the users. For that reason, the outer casing of the wood golf club head is generally made of light materials, such as carbon fiber, to reduce total weight of the golf club. Nevertheless, the use of carbon fiber may easily reduce the strength of the cup-shaped striking faceplate due to uneven pressure in the formation processes of the faceplate.
- To overcome the defect, a conventional method for manufacturing a cup-shaped striking faceplate of a wood golf club head is disclosed, and the cup-shaped striking faceplate produced according to this conventional method is shown in
FIG. 1 . The conventional method for manufacturing the cup-shaped striking faceplate includes preparing acarbon fiber material 91, amold 92 including afirst mold 921 and asecond mold 922 jointly forming a mold cavity “C”, asilicone compressing member 93 conforming to the shape of the mold cavity “C”; disposing thecarbon fiber material 91 in the mold cavity “C”, then disposing thesilicone compressing member 93 close to the cavity mold “C”; and applying an external force to thecarbon fiber material 91 by thermal expansion of thesilicone compressing member 93. Thecarbon fiber material 91 is therefore compressed and cured under heat to form a desired shape, thus obtaining the cup-shaped striking faceplate. The cup-shaped striking faceplate may be used to produce a wood golf club head. - However, in the conventional method for manufacturing a cup-shaped striking faceplate of a wood golf club head, the
silicone compressing member 93 may continuously expand when heated by themold 92. Then, thesilicone compressing member 93 cools down and shrinks. Thecompressing member 93 may consequently deteriorate when undergoing several times of temperature changes and should be replaced, which adversely increases the production cost of the cup-shaped striking faceplate. Such a method for manufacturing a cup-shaped striking faceplate of a wood golf club may be seen in Taiwan patent No. 1260237. - It is therefore the objective of this invention to provide a method for manufacturing a cup-shaped striking faceplate of a wood golf club for producing a light cup-shaped striking faceplate with high strength.
- Another objective of this invention is to provide a method for manufacturing a cup-shaped striking faceplate of a wood golf club without using a large-sized silicone compressing member required in a conventional method. Thus, the production cost resulting from frequent replacements of the silicone compressing member as required in the conventional manufacturing method is reduced.
- The present invention fulfills the above objectives by providing, in a first aspect, a method for manufacturing a cup-shaped striking faceplate of a wood golf club head including preparing a heat-compressing mold having a mold cavity, preparing a base plate having a first surface and a second surface opposite to the first surface, preparing a thermally expanding sheet, placing the base plate in the mold cavity by adhering the first surface of the base plate to an inner surface of the mold cavity, placing the thermally expanding sheet on the second surface of the base plate, and compressing the base plate and the thermally expanding sheet using the heat-compressing mold to form the base plate as the cup-shaped striking faceplate under heat compression. The cup-shaped striking faceplate includes a bottom wall and a lateral wall having a height of 5 to 40 mm.
- In a second aspect, the present invention provides a method for manufacturing a cup-shaped striking faceplate of a wood golf club head including preparing a heat-compressing mold having a mold cavity, preparing a base plate having a first surface and a second surface opposite to the first surface, preparing a thermally expanding sheet, placing the thermally expanding sheet on the second surface of the base plate; placing the combined base plate and thermally expanding sheet in the mold cavity by adhering the first surface of the base plate to an inner surface of the mold cavity, and compressing the base plate and the thermally expanding sheet using the heat-compressing mold to form the base plate as the cup-shaped striking faceplate under heat compression. The cup-shaped striking faceplate comprises a bottom wall and a lateral wall having a height of 5 to 40 mm.
- In a preferred form shown, a declined angle between the largest and smallest outer diameters of the lateral wall is equal to or smaller than 15°.
- In the preferred form shown, the thermally expanding sheet has a thickness of 0.5 to 5 mm.
- In the preferred form shown, the thermally expanding sheet has a Shore hardness value of 40 to 100.
- In the preferred form shown, the size of the thermally expanding sheet is equal to or smaller than the size of the base plate.
- In the preferred form shown, the base plate is a carbon fiber material.
- In the preferred form shown, the base plate includes a carbon fiber material and a metal sheet. The metal sheet of the base plate is adhered to the mold cavity.
- In the preferred form shown, the metal sheet is made of “6-4” type of titanium alloy.
- With accordance to the method for manufacturing the cup-shaped striking faceplate of the wood golf club head in the present invention, the base plate receives an external force evenly applied by the heat-compressing mold through the thermally expanding sheet placed on the second surface of the base plate. Thus, distribution of the fiber and resin of the base plate containing carbon fiber material is improved, and the strength of such a light cup-shaped faceplate is enhanced consequently.
- Moreover, the method for manufacturing a cup-shaped striking faceplate of a wood golf club head according to the present invention replaces a conventional large-sized silicone compressing member with the thermally expanding sheet placed on the second surface of the base plate. Thus the production cost resulting from frequent replacements of the large-size silicone compressing member as required in the conventional manufacturing method is reduced.

- With references to
FIGS. 2 and 3 , a method for manufacturing a cup-shaped striking faceplate of a wood golf club head according to the present invention includes placing abase plate 1 in a mold cavity “C” of a heat-compressing mold “M”, placing a thermally expandingsheet 2 on thebase plate 1, and heating the thermally expandingsheet 2. The thermally expandingsheet 2 may expand under heat. Thus, the thermally expandingsheet 2 and the heat-compressing mold “M” may jointly compress thebase plate 1 to form a cup-shapedstriking faceplate 3 under heat compression. - Specifically, the
base plate 1 includes a first surface 1 a and asecond surface 1 b opposite to the first surface 1 a. Thebase plate 1 may be a carbon fiber material or may include ametal sheet 11 and acarbon fiber material 12. In such a case, the first surface 1 a is located on themetal sheet 11, and thesecond surface 1 b is located on thecarbon fiber 12. Preferably, the metal sheet is a “6-4” type of titanium alloy as shown inFIG. 5 . When thebase plate 1 containing carbon fiber material is used to produce a cup-shapedstriking faceplate 3, the weight of saidfaceplate 3 can be reduced. - The heat-compressing mold “M” includes a first mold “M1” and a second mold “M2”. The mold cavity “C” is located in the second mold “M2”.
- The thermally expanding
sheet 2 includes afirst surface 2 a and asecond surface 2 b opposite to thefirst surface 2 a. The thermally expandingsheet 2 is expandable under heat transferred from the heat-compressing mold “M”. Preferably, the thermally expandingsheet 2 has a thickness of 0.5 to 5 mm, and a Shore hardness value of 40 to 100. In this embodiment, the thermally expandingsheet 2 is a silicone sheet. - The
base plate 1 may be placed in the mold cavity “C” by adhering the first surface 1 a of the base plate to an inner surface of the mold cavity “C”. The thermally expandingsheet 2 is then placed on thesecond surface 1 b of thebase plate 1 by adhering thefirst surface 2 a of the thermally expandingsheet 2 to thesecond surface 1 b of thebase plate 1. In addition, the size of the thermally expandingsheet 2 can be equal to or smaller than the size of thebase plate 1. When the size of the thermally expandingsheet 2 is smaller than the size of thebase plate 1, the expandingsheet 2 is aligned with thebase plate 1 at the center. Namely, the thermally expandingsheet 2 is aligned with the cup-shapedstriking faceplate 3 at the center after thebase plate 1 forms the cup-shapedstriking faceplate 3. - With similar concepts, one having ordinary skill in the art may otherwise adhere the
first surface 2 a of the thermally expandingsheet 2 to thesecond surface 1 b of thebase plate 1, and then mount the combined thermally expandingsheet 2 andbase plate 1 in the mold cavity “C” by adhering the first surface 1 a of thebase plate 1 to the inner surface of the mold cavity “C”. - When the
base plate 1 and the thermally expandingsheet 2 have been arranged, the first mold “M1” and the second mold “M2” may jointly compress thebase plate 1 and the thermally expandingsheet 2. The thermally expandingsheet 2 therefore expands under heat, and consequently applies an external force to thebase plate 1 to form the cup-shapedstriking faceplate 3 under heat compression. The cup-shapedstriking faceplate 1 may be obtained in the mold cavity “C” after the first mold “M1” is removed. - With references to
FIG. 4 , the cup-shapedstriking faceplate 3 produced according to the method for manufacturing the cup-shaped striking faceplate of the wood golf club head in the present invention includes abottom wall 31 and alateral wall 32 having a height of 5 to 40 mm. - With references to
FIG. 5 , in the case of forming a cup-shapedstriking faceplate 3 having a higher lateral wall, the heat-compressing mold “M” may preferably include a first mold “M1”, a second mold “M2” and an intermediate mold “M3”. The mold cavity “C” is formed by the second mold “M2” and the intermediate mold “M3”, as it can be known by one ordinarily skilled in the art. - In this embodiment, one may sequentially mount the
base plate 1 and the thermally expandingsheet 2 in the mold cavity “C” by adhering thefirst surface 1 b of thebase plate 1 to the inner surface of the mold cavity “C” and adhering thefirst surface 2 b of the thermally expandingsheet 2 to thesecond surface 1 b of thebase plate 1. Because of thebase plate 1 includes themetal sheet 11 and thecarbon fiber material 12, therefore the first surface 1 a formed by themetal sheet 11 of thebase plate 1 is adhered to the mold cavity “C”, and thesecond surface 1 b formed by thecarbon fiber material 12 of thebase plate 1 is adhered to the thermally expandingsheet 2. - Next, the first mold “M1”, the second mold “M2” and the intermediate mold “M3” jointly compress the
base plate 1 and the thermally expandingsheet 2. Thus, the thermally expandingsheet 2 expands under heat, such that thebase plate 1 is able to form the cup-shapedstriking faceplate 3 under heat compression as previously described. - With references to
FIG. 6 , the cup-shapedstriking faceplate 3 manufactured according to the above method still includes thebottom wall 31 and thelateral wall 32. Furthermore, a declined angle “θ” between the largest and smallest outer diameters of thestriking faceplate 3 is equal to or smaller than 15°. - Accordingly, the
base plate 1 can be evenly compressed by thermal expansion of the thermally expandingsheet 2, and the thermally expandingsheet 2 and the heat-compressing mold “M” can jointly compress thebase plate 1 to form the cup-shapedstriking faceplate 3. - As a summary of all, with accordance to the method for manufacturing the cup-shaped striking faceplate of the wood golf club head in the present invention, the base plate receives an external force evenly applied by the heat-compressing mold through the thermally expanding sheet placed on the second surface of the base plate. Thus, distribution of the fiber and resin of the base plate containing carbon fiber material is improved, and the strength of such a light cup-shaped faceplate is enhanced consequently.
- Moreover, the method for manufacturing a cup-shaped striking faceplate of a wood golf club head according to the present invention replaces the conventional large-sized silicone compressing member with the thermally expanding sheet placed on the second surface of the base plate. Thus the production cost resulting from frequent replacements of the large-sized silicone compressing member is reduced.
