Description

1301770 IX. Description of the Invention: [Technical Field] The present invention relates to a golf glass/dry, and in particular to a weight structure of a golf club head and a method of manufacturing the same. [Prior Art] The design of the golf club head is lightweight, in order to increase the golf club head before the swinger, and the hitting panel containing the metal material, and the fiber composite ^ ^ , the ten piece ® The layered shell is set on the side of the spheroidal panel, because the density of the fiber ray Me e x 4 complex σ material is much lower than that of the metal 疋 疋 边 边 边 边 边 边 边 边 边 e e e e e e In addition, in order to avoid the ball's center of gravity, the center of gravity is biased toward the batting panel, so that it is difficult to control the force of hitting the ball/the angle of the hitting surface, and the smashing of the ball (4) North (four)...—H again The moon and the bottom of the body are correspondingly provided with a matching device, so that the center of gravity of the club head is offset to the back and bottom of the casing. Conventionally, the method of placing the weighting device on the body of the fiber composite material can be roughly divided into two types, one of which is based on the number of the shell materials which are laminated from the number of fiber composite material sheets. Disposing the hole 'and placing the weight device in the corresponding matching hole', and placing the housing in the man-hot forming mold, and inserting the gas into the thermoforming mold to expand and inflate The shell pre-material is extruded under the tension of the air bag, and the right eight-day b is attached to the inner wall of the thermoforming mold, and the shell is pre-formed in the thermoforming mold. ^ #,么,甲,,二二 After heating and curing, the weight device can be fixed in the housing arrangement hole formed by curing the fiber material. Another method is shown in U.S. Patent No. 6,248,025, which incorporates a weighting device in a housing preform 41301770 which is stacked from a plurality of fiber composite sheets, and then the housing is folded.曰 一 一 一 、 、 , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , After the curing: After curing, the casing with the weight device is formed. #t :二ί: The same problem exists in both methods'- is that its weight ί cannot be adjusted according to the individual habits of the swinger, and its weight device cannot be accurately positioned when the shell is prefabricated. When the hot-carrying grip is used to perform the curing process from the forming crucible, and it is squeezed by the tension of the inflated air bag, it has the ability to push the field. ^ /, the force of pushing the air bag is different. The tortuous angle of the inner wall of the thermoforming mold produces a monthly shirt sound, which causes a displacement deviation when attached to the inner wall of the thermoforming mold, so that the left balance weight device cannot be accurately positioned, and the center of gravity of the club head cannot be positioned at the sub-portion. g Dong Ri in the expected position, affecting the performance of the swinger 0 [Invention] The main purpose of this configuration is to provide a new golf club head with its counterweight according to the swinger The habits of the different proportions: Adjust the weight and center of gravity of the club head that is most suitable for the swing. . In order to achieve the foregoing object, the present invention has a ball striking head structure comprising a ball striking panel and a casing set on the back side of the smashing ball panel, the main body of the casing Formed by a fiber laminate material or a fiber kneading material, the bottom surface of the bean top cover plate is formed on the skirt portion phase & 'on the shell portion' or the bottom plate; - the weight positioning portion 'the bottom of the weight positioning portion Fixing #positioning base, the fixed 1301770 • is provided with a positioning portion on the base, and a weight device is detachably disposed on the ^ weight positioning portion, and is coordinated with the positioning portion of the positioning base; The weight devices are not concealed in the casing, and are not fixed in the casing, and are detachably disposed on the weight positioning portion and positioned by the positioning portion of the positioning base, so the swinger can According to its own choice, it is most suitable for its own weight device to adjust the weight and center of gravity of the club head. Another main object of the present invention is to provide a new golf club head manufacturing method that overcomes the above-mentioned golf club head. Loss of positioning of the heavy device' leads to the center of gravity of the club head The problem is that the method is set at a predetermined position. In order to achieve the foregoing object, the present invention firstly positions the positioning base on a base positioning portion of an inner wall of a thermoforming mold, the shape of the base positioning portion corresponding to the weight of the body. The positioning portion further covers the fiber composite material prepared in advance on the inner wall of the thermoforming mold to form a shell pre-material, and then the air bag is placed in a heat forming mold to be inflated, and the shell is fully pre-formed with the tension. Attached to the inner wall of the thermoformed crucible, the shell is preheated in a thermoforming mold to solidify and form a shell. Although the shell is pre-formed in the thermoforming mold and is also squeezed by the expanded air bag, The positioning base is positioned on the base positioning portion of the inner wall of the thermoforming mold, so that the displacement of the air bag is not affected by the pushing of the air bag, so that the weight device can be accurately positioned with the positioning portion of the positioning base, and The casing of the invention can be bonded to the ball striking panel in a bonding manner, or can be placed in the thermoforming mold together with the ball striking panel, and combined with the batting panel while being solidified. 1301770 ° month with reference to the "" - ^ map $ Chu -闰..., for this A preferred embodiment of the golf club head structure comprises: a dry hitting panel (1 〇), which may be 44·4 疋 属 属 属 亦可 亦可 亦可 、 、 a corner 隅 or may be provided with a club body for the club; ... for the Erf a shell (20), set in the ball striking face = body (2 〇) mainly by the fiber laminate Or fiber kneading::, 乍成!
