Description

Technical field:

[0001] The utility model relates to the technical field related to golf clubs, and more specifically to an improved golf head. Background technology:

[0002] A golf club consists of three parts: the head, the shaft and the grip. The head is generally made of metal and uses a tungsten alloy weight element.

[0003] The ball head is generally hollow inside, that is, a hollow groove extending forward is formed in the middle of the rear wall of the main body, and the rear cover plate needs to be covered at the rear of the hollow groove. At the same time, a slot extending toward the bottom is formed in the middle of the bottom of the hollow groove, and the rear of the slot extends out of the rear wall of the main body. The bottom rear assembly 10a needs to be inserted into the slot and covered, such as Figure 1 As shown, the three are then integrated by degreasing and sintering, and then the left rear wall surface of the bottom rear component and the left rear wall surface of the main body are processed and engraved. However, due to the irregular shape of the golf head, it can only be clamped and fixed by a special mold or fixture and then painted, and the processing efficiency is low and the effect is poor;

[0004] At the same time, if Figure 1 As shown, if the code is directly formed when the main body and the bottom rear assembly 10a are formed, there will be a part of the code groove between the left rear wall of the bottom rear assembly and the left rear wall of the main body. At this time, in the later sintering process, the code groove will inevitably be affected and secondary processing is also required, and the effect is very poor.

[0005] At the same time, if Figure 2 As shown, the rear wall plate of the bottom rear assembly 10a is just in the slot, and the slot is in the lower part of the empty slot, and the left and right sides of the lower part of the empty slot are formed with downwardly extending end grooves 2a, and the end grooves 2a are below the rear wall plate of the lower part of the main body. This structure makes the main body produce an undercut structure when the mold is manufactured. At this time, a slanted top slider structure must be set for demolding, that is, the mold block and the slanted top slider at the empty slot and the blocking end groove 2a need to be moved out before the main body can be demolded, which greatly increases the difficulty of demolding. Utility model content:

[0006] The purpose of the utility model is to overcome the shortcomings of the prior art and provide an improved golf ball head, which can directly form all the code grooves on the split block when the split block is formed, and the code does not need to be formed on the golf ball body, so that after the sintering is completed, no secondary processing is required, and the processing efficiency is greatly improved. In addition, the bottom of the empty groove of the golf ball body is not covered by the corresponding rear wall plate, so that it is easy to demould, and there is no need to use mold blocks such as inclined top sliders. The structure is simple and the manufacturing is convenient.

[0007] The solution of the utility model to solve the technical problem is:

[0008] An improved golf head comprises a golf head body, wherein a hollow groove extending downward is formed in the middle of the rear wall surface of the golf head body, an inner groove extending forward is formed near the bottom of the rear wall surface of the golf head body, the inner groove is communicated with the hollow groove, an embedding groove extending leftward or rightward is formed at the left and right sides of the rear part of the inner groove, the rear end of the embedding groove extends out of the rear wall surface of the golf head body, the upper part of the embedding groove is communicated with the hollow groove, the bottom of the inner groove extends out of the bottom surface of the golf head body, the bottom surface of the bottom wall plate of the split block is pressed against the front wall surface at the bottom of the inner groove, the bottom surface of the split block and the bottom surface of the golf head body are spliced ​​to form a whole bottom surface, the left and right parts of the rear wall plate of the split block are both formed with extension parts, the extension parts are embedded in the corresponding embedding grooves, the upper part of the extension part and the upper part of the rear wall plate of the split block cover the lower part of the hollow groove;

[0009] The bottom surface of the split block is formed with a first code groove, and the top surface of the extension portion from the left part of the rear wall surface of the rear wall plate of the split block to the left side is formed with a code groove.

[0010] The front wall surface at the bottom of the inner groove is formed with a protrusion extending along the rear part of the front wall surface of the inner groove, and the upper part of the rear wall surface of the protrusion is formed with a plurality of mortises with trapezoidal cross-sections, and the front wall surface of the bottom wall plate of the split block is formed with a plurality of tenons with trapezoidal cross-sections, and the tenons are inserted into corresponding mortises, and the two cooperate with each other, and the rear wall surface of the protrusion is tightly attached to the front wall surface of the bottom wall plate of the split block.

[0011] The outstanding effects of the utility model are:

[0012] All the code grooves can be directly formed on the split block during molding, and there is no need to form codes on the golf ball body, so that after sintering, no secondary processing is required, and the processing efficiency is greatly improved. In addition, the bottom of the empty groove of the golf ball body is not covered by a corresponding rear wall plate, which makes it easy to demould without using mold blocks such as inclined top sliders. The structure is simple and the manufacturing is convenient. Description of the drawings:

[0020] Figure 8 yes Figure 7 Schematic diagram of the local structure of the angle change Specific implementation method:

[0021] For example, see Figures 3 to 8 As shown, an improved golf head comprises a golf head body 10, wherein a hollow groove extending downward is formed in the middle of the rear wall surface of the golf head body 10, an inner groove 11 extending forward is formed near the bottom of the rear wall surface of the golf head body 10, the inner groove 11 is communicated with the hollow groove, an embedded groove 12 extending leftward or rightward is formed at the left and right sides of the rear part of the inner groove 11, the rear end of the embedded groove 12 extends out of the rear wall surface of the golf head body 10, the upper part of the embedded groove 12 is communicated with the hollow groove, and the bottom of the inner groove 11 extends out of the bottom surface of the golf head body 10;

[0022] The golf head body 10 adopts this structure, so that when it is manufactured through a mold (powder is injected into the mold and then sintered, i.e., metal powder injection molding technology), no undercut structure is generated (the undercut structure is that when demolding, the outlet at the bottom is smaller than the upper size of the product or the outlet at the top is smaller than the size of the product at the bottom, and demolding cannot be achieved), so it does not need to set mold blocks such as a tilted top slider, which facilitates demolding manufacturing.

[0023] Furthermore, the bottom surface of the bottom wall plate of the split block 20 is pressed against the front wall surface at the bottom of the inner groove 11, and the bottom surface of the split block 20 is spliced ​​with the bottom surface of the golf head body 10 to form the entire bottom surface. The left and right parts of the rear wall plate of the split block 20 are both formed with extensions 21, and the extensions 21 are embedded in the corresponding embedding grooves 12, and the upper part of the extension 21 and the upper part of the rear wall plate of the split block 20 cover the lower part of the empty groove;

[0024] The bottom surface of the split block 20 is formed with a first code groove 1 , and the top surface of the extension portion 21 from the left portion of the rear wall surface of the rear wall plate of the split block 20 to the left side is formed with a code groove 2 .

[0025] Due to the extension part 21 of the split block 20, the left part of the rear wall surface to the rear wall surface of the extension part 21 can be directly formed with the code groove 2 during mold manufacturing. At the same time, the first code groove 1 is formed on the bottom surface of the split block 20, and there is no need to form the code groove on the golf head body 10, etc., which makes it easy to manufacture. Moreover, the first code groove 1 and the code groove 2 are not located at the connecting gap between the two, so that after the two are degreased and sintered in the later stage, the first code groove 1 and the code groove 2 will not be affected, so that there is no need for secondary processing in the later stage.

[0026] Furthermore, the front wall surface at the bottom of the inner groove 11 is formed with a protrusion 13 extending along the rear part of the front wall surface of the inner groove 11, and the upper part of the rear wall surface of the protrusion 13 is formed with a plurality of mortises 14 with a trapezoidal cross section, and the front wall surface of the bottom wall plate of the split block 20 is formed with a plurality of tenons 22 with a trapezoidal cross section, and the tenons 22 are inserted into the corresponding mortises 14, and the two cooperate with each other, and the rear wall surface of the protrusion 13 is tightly attached to the front wall surface of the bottom wall plate of the split block 20. The mortise and tenon structure makes the connection between the split block 20 and the golf head body 10 more firmly.

[0027] Furthermore, a slot 111 extending to the left is formed on the left side wall of the inner groove 11 at the left side of the rear wall surface of the protrusion 13, and the rear part of the slot 111 extends out of the rear wall surface of the golf head body 10. An extended mounting portion 24 extending to the left is formed on the left side wall of the bottom wall plate of the split block 20, and the extended mounting portion 24 is inserted into and matched with the slot 111.

[0028] Furthermore, a connecting pipe portion 15 extending upward is formed on the right portion of the top of the golf head body 10 .

[0029] Furthermore, the bottom surface of the end of the extension portion 21 is formed with a clamping portion 211 extending toward the bottom, and the clamping portion 211 is inserted into the downwardly extending lower groove 121 formed on the bottom surface of the end of the embedded groove 12 and cooperates with the lower groove 121.

[0030] The clamping portion 211 makes the split block 20 and the golf head body 10 more firmly joined and has a better effect.

[0031] The above implementation modes are only used to illustrate the present invention, but not to limit the present invention. Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also belong to the scope of the present invention. The scope of patent protection of the present invention should be limited by the claims.
