TWI284550B - Shell body of magnesium alloy die-casting golf club head - Google Patents

Abstract

Provided is a shell body of magnesium alloy die-casting golf club head. The golf club head has a top surface, a ball-hitting surface, a bottom surface, a toe part, a heal part, and a neck part. The internal part of the golf club is hollow. A division line is set from the highest point of the top surface of the club head, along the external protruding end of the toe part, and passing through the bottom part and the external protruding end of the heel part. The club head is therefore divided into a ball-hitting component and a shell body, so that the division surface of the shell body exhibit the largest opening. The shell body is the unity formed by die casting of magnesium alloy.

Description

1284550 IX. Description of the Invention: [Technical Field of the Invention] The present invention relates to a golf club, and refers to a casing of a magnesium alloy die-cast golf club head. 5 [Prior Art] As disclosed in US 5,494,281, the production of golf club head shells made of magnesium alloys and the manufacture of striking panel sheets made of titanium alloy or alloy or ceramic materials has a light weight. The advantages of cheapness and unit price (compared to the titanium alloy of light metal) can be rapidly produced in a 10 way by dieeasting in production. The disadvantage is that · due to the production of pressure scale, for the reason of demoulding, The shell (90) will form a thicker area at the top (91), the toe (92), the bottom K93) and the heel (94) (as shown in the first person, the nine figure). This structure is not conducive to the design of the oversized club head. ι, as disclosed in Taiwan Patent Publication No. 590028, reveals that the hollow head is divided into 15 parts - the front side shell part and the back side shell part, and the rear side shell part can be stainless steel, Shao or town or Made of alloy, but the case did not reveal how the head should be cut, in other words the aforementioned problems have not been solved. SUMMARY OF THE INVENTION - The main object of the present invention is to provide a magnesium alloy die-cast golf club head shell, the shell of which can be molded by magnesium alloy, and there is no structural weight generation, so that the head can be directed Oversized design. * ▲ In order to achieve the above object, a magnesium alloy is provided according to the present invention, which is a housing of a golf head having a top surface, a hitting surface of 12.84550, a bottom surface, and a toe. a heel portion and a neck portion, the interior is hollow, and a dividing line is arranged from a high point of the top surface of the tip of the rod to the concave end of the toe portion and the concave end of the heel portion, and the head is divided into a ball striking member and A housing has a largest opening for the split surface of the housing, and the housing is formed by a town-alloy binding. [Embodiment] An embodiment is described with reference to the following figures: As shown in the first to third figures, the shape of the casing (20) according to the embodiment of the present invention is a die casting of a magnesium alloy. Formed with a top portion (21), a toe portion (22), a bottom portion (23), a heel portion (24) and a neck portion (25), the inner hollow having an opening (26) at the periphery of the opening end surface A groove (27) is provided. As shown in the fourth to seventh figures, in order to facilitate the die-casting of the die-casting and to maintain the wall thickness of the casing to be thin without causing a thick thickness, the head 15 (10) is deliberately from the top surface thereof ( 11) The highest point (111) is the dividing line (50), along the outermost convex end (121) of the toe (12) of the club head, passing through the bottom of the club head (13) and the heel of the club head (14). The convex end (141) is wound in a circle so that the split surface of the casing (20) has the largest opening (26), so that even the die of the die-casting mold (not shown, that is, the hollow of the casing (20) Internally) is removed from the housing (20) and allows the housing 2(20) to be kept thick at its top (21), toe (22), bottom (23) and heel (24) positions. With respect to the casing (20) of the present embodiment, it is necessary to additionally manufacture a ball striking face member (30) (indicated by an imaginary line in the drawing) and the casing (20) to form a golf club head (10). . The ball striking face member (30) may be formed by casting or forging, such as titanium alloy, stainless steel l28455〇 steel, or aging steel, and then joined to the casing (20). The housing (20) of the embodiment is provided with a groove (27), and the ball striking member (3) is oppositely provided with a tenon (31) which can be engaged with the groove (27), and then an adhesive is used, for example. % oxygen resin or the like is joined. 5 Since the shell wall is thin and not heavy, it is allowed to enlarge the head as a whole, and a weight (4〇) can be arranged at the bottom of the casing (23) near the rear end, as shown in the fifth and seventh figures. In order to make the club head focus on the past and the future. • It should be specially stated that since the bottom of the club head (13) is usually flat, the position of the dividing line can have a large elastic change without affecting the de-10 mode. In this embodiment, the position of the dividing line at the bottom is Try to move in the direction of the ball striking face, so that the bottom can be allowed to change the shape and set the trademark, model and so on. In the fifth figure, the top (21) of the casing must have a large thickness of meat in order to provide the groove (9), which is an implementation choice. Some club heads have a slightly flat top surface. Therefore, there is no highest point, but the position of the dividing line can be selected from η, that is, any = or • passing through the highest plane area will affect the demoulding and not Will form a heavy weight. "P: In addition, the neck of the club head is formed integrally with the housing, and a neck tube is inserted into the housing. ', 1 another
