In the configuration shown, in the direction of the interval width "GW" (that is, a direction extending in a direction between the first surface 78 and the outer surface of the golf club head body 14 and perpendicular to the interval depth direction) The width of the interval 86 is also between 0.01 inches and 1 inch, but other values and ranges are also possible. For example, in some constructions, the width of the gap 86 is between 0.01 inches and 1.5 inches. In some constructions, the width of the interval 86 can be 0.01, 0.05, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0, 1.1, 1.2, 1.3, 1.4, and 1.5 inches.

Referring to FIG. 6, the space 86 is filled with a filling material 90. In the illustrated construction, the filler material 90 may be an elastic material such as a cladding, resin, rubber, silicone, or other elastic material (s), although other constructions may contain different materials.

FIG. 7 illustrates an embedded casting processing program 94 for constructing the golf club head 10 and for coupling the HDMP 66 to the golf club head body 14, as shown in FIGS. 1-6.

Referring now to FIG. 7, the embedded casting program 94 includes a first step 98, which constitutes the HDMP 66. The HDMP 66 is made by, for example, machining, casting, metal injection molding, direct laser sintering, powder metal forming procedures, or other suitable processing methods known to those skilled in the art.

Referring also to FIG. 8, when the HDMP 66 is first constructed, the HDMP 66 initially contains at least one protrusion 102. In the construction shown, the HDMP 66 contains two projections 102 in the form of posts. The two protrusions 102 extend from the first surface 78 of the HDMP 66 base portion 70 (ie, as vertically) and are integrated to form a part of the HDMP 66 (ie (Such as a monolithic extension). The protrusions 102 define axes 106, 108 that are displaced from each other. In the described construction, the two axes 106, 108 are parallel to each other, but in some constructions the two axes 106, 108 are inclined relative to each other or intersect with each other. Each of the protrusions 102 extends away from the first surface 78 along its individual axis 106, 108. In the construction, each of the protrusions 102 extends 0.2 to 10 inches from its first surface 78 along its individual axis 106, 108, but other constructions may include different values and ranges. In some constructions, each of the protrusions 102 extends between 0.2 and 1 inch away from the first surface 78. In some constructions, each of the protrusions 102 extends between 0.2 and 5 inches away from the first surface 78. In some constructions, one of the protrusions 102 extends longer than the other protrusion 102 away from the first surface 78. In some constructions, the HDMP 66 contains only a single protrusion 102 that extends a longer distance (eg, between 5 and 10 inches). In some constructions, the HDMP 66 contains a plurality of protrusions 102 each extending a short distance (eg, between 0.2 and 5 inches).

Each of the protrusions 102 also has a cross-sectional area. In the construction, each of the protrusions 102 has a circular cross-sectional section, which defines a cross-sectional area of 0.005 square inches to 0.010 square inches, but other constructions may contain different values and ranges. In some constructions, each of the protrusions 102 has a cross-sectional area of 0.005 square inches to 0.015 square inches. In some constructions, each of the protrusions 102 has a cross-sectional area of about 0.005 square inches. In some constructions, the cross-sectional area of the protrusions 102 may include 1% to 40% of the first surface 78. In some constructions, the cross-sectional areas of the protrusions 102 may include 1%, 5%, 10%, 15%, 20%, 25%, 30%, 35%, and 40% of the first surface 78. In some constructions, the cross-sectional area approaches or equals the area of the first surface 78. In some constructions, one of the protrusions 102 has a larger cross-sectional area than the other protrusion 102. Other constructions may contain various other numbers of protrusions 102, including a single protrusion Out 102, three out 102 and so on. Other protrusions may also contain various other shapes, sizes, and cross-sectional areas that are different from those described above. For example, in some constructions, the HDMP 66 may contain only a single protrusion 102, but this one has a large cross-sectional area. In some constructions, one of the protrusions 102 has a first cross-sectional area, and the other protrusion 102 has a second, different cross-sectional area.

In some constructions, after forming the HDMP 66, a coating may be applied to the HDMP 66, which may protect the HDMP 66 during subsequent steps of the embedded casting program 94. In many constructions, the coating can preserve the structural integrity of the HDMP 66 by preventing oxidation during subsequent casting processes, as described in further detail below. The coating may be made of any material sufficient to withstand high temperatures, ie as previously discussed. For example, the coating may be made of ceramic, metal, alloy ceramic, silicone, silicon salt, or any other material or combination of materials that can withstand high temperatures. Exemplary alloy ceramic coatings may include, but are not limited to, tungsten carbide-cobalt, chromium carbide-nickel chromium, oxide ceramics, such as chromium oxide and aluminum oxide, molybdenum, iron, and nickel. Exemplary metal coatings may include, but are not limited to, tungsten carbide powder, nitride powder, zirconia, diamond powder, cerium oxide, and alumina. Further, the coating can be applied using any procedure, such as, for example, chemical vapor deposition, thermal spraying, or painting. In some constructions, the thickness of the coating can range from 25 micro-inches to 400 micro-inches. In some constructions, a second coating can be applied on the first coating, and the thickness of the second coating can range from 5 microinches to 60 microinches.

Referring to Figures 7, 9 and 10, the embedded casting program 94 further includes a second step 110, that is, placing the HDMP 66 in a sealing wax injection mold, and a third step 114, that is, sealing wax 118 (such as a coating sealing wax) ) Is injected into the sealing wax injection mold, thereby partially embedding the HDMP 66 into a wax shell or sheath.

For example, and referring to FIG. 9, in the construction, the tool 120 is associated with the HDMP 66 placed next to each other. The tool 120 includes a flat plate 125 having at least one hole 103 configured to receive the protrusion 102 of the HDMP 66 and a lip configured to receive at least a portion of the base portion 70 of the HDMP 66 Or steps or protrusions or edges 121 (Figure 9 is a schematic representation of the HDMP 66 and the tool 120, although only a single protrusion 102 and hole 103 are shown at the same time, as described above, the HDMP 66 may have two or More protrusions 102, and the tool 120 may have two or more holes 103). The lip 121 includes a lip height “LH” extending from the flat plate 125 toward the HDMP 66 and corresponding to the interval depth “GD”. In the configuration, the height of the lip 121 is between 0.01 inches and 1 inch, but other values and ranges are also possible. For example, in some constructions, the height of the lip 121 may be between 0.01 and 1.5 inches. In some constructions, the height of the lip 121 may be 0.01, 0.05, 0.1, 0.15, 0.2, 0.25, 0.3, 0.35, 0.4, 0.45, 0.5, 0.55, 0.6, 0.65, 0.7, 0.75, 0.8, 0.85, 0.9 , 0.95, 1.0, 1.05, 1.1, 1.15, 1.2, 1.25, 1.3, 1.35, 1.4, 1.45 or 1.5 inches. Further, the lip 121 includes a lip width “LW” extending in a direction parallel to the flat plate 125 and perpendicular to the lip height direction. The lip width "LW" corresponds to the interval width "GW". In the configuration, the width “LW” of the lip 121 is between 0.01 inch and 1 inch, but other values and ranges are also possible. For example, in some constructions, the width of the lip 121 may be between 0.01 and 1.5 inches. In some constructions, the width of the lip 121 may be 0.01, 0.05, 0.1, 0.15, 0.2, 0.25, 0.3, 0.35, 0.4, 0.45, 0.5, 0.55, 0.6, 0.65, 0.7, 0.75, 0.8, 0.85, 0.9 , 0.95, 1.0, 1.05, 1.1, 1.15, 1.2, 1.25, 1.3, 1.35, 1.4, 1.45 or 1.5 inches. Further, in the construction, the lip 121 has a rectangular cross section. In other constructions, the lip 121 may take any cross-sectional shape. For example, the lip 121 may be triangular, cylindrical, pyramidal, spherical, cubic, or any suitable cross-sectional shape.

When the sealing wax 118 is injected into the tool 120, the sealing wax 118 surrounds at least a part of the HDMP 66 to form a wax shell and a sheath, as shown in FIG. 10. This procedure can at least partially embed the HDMP 66 into the sealing wax 118 in a precise and repeatable manner. That is, as shown in FIG. 10, the sealing wax 118 is at least partially embedded in the flange 74, the top side part 67 of the HDMP 66, but a part of the base part 70 received by the lip 121, and two convex parts The output 102 is left exposed or set (projected) outside the sealing wax 118. In some constructions, only a portion of the base portion 70 is exposed outside the sealing wax 118. In other constructions, the entire base portion 70 may be exposed outside the sealing wax. In other constructions, the entire base portion 70 may be exposed outside the sealing wax. In other constructions, the entire base portion 70 and a portion of the top side portion may be exposed outside the sealing wax 118.

7 and 10, the embedded casting processing program 94 further includes a fourth step 122, that is, adding a wax sealing element to the wax sealing equipment, and a fifth step 126, coating the wax sealing equipment with a ceramic material. That is, as shown in FIG. 10, for example, the sealing wax 118 forms at least one wax element for the sealing wax component of the golf club head 10. In some constructions, the sealing wax assembly has a main sealing wax body. Each wax sealing element is an integral sealing wax component attached to the main sealing wax body for constituting the golf club head body 14. In some constructions, a cone or cup (not shown) can be attached to the wax seal assembly on the top side of the wax seal assembly. This cone contains an opening through which molten material can be poured during later steps.

During the fifth step 126, the sealing wax component can be immersed in a liquid ceramic slurry, thereby forming a ceramic shell 130 on the sealing wax component (FIG. 10). The cone part of the wax seal assembly is left open on the top side. The wax sealing assembly is provided with a plurality of ceramic coatings to form the ceramic shell 130, because the plurality of ceramic coatings can reach a desired strength and is sufficient to pour the molten material into The molten material is held in a later step in the ceramic case 130. Each coating is allowed to dry before the next coating is applied. That is, as shown in FIG. 10, during this step, the HDMP 66 is at least partially embedded in the combination of the sealing wax 118 and the ceramic shell 130. The two protrusions 102 can be fitted in the ceramic shell 130, but the protrusions 102 do not penetrate the ceramic shell 130. In addition, as shown in FIG. 10, the space 86 generated by the lip 121 and accommodating the base portion 70 can be completely filled by the ceramic case 130.

Referring to FIG. 7, the embedded casting program 94 further includes a sixth step 134, that is, melting and removing the sealing wax 118. In the construction, after the ceramic shell 130 is dried, the sealing wax component 118 may be melted by turning the sealing wax component and heating the sealing wax component. During the sixth step 134 and as further described in the present disclosure, the HDMP 66 is rigidly held in place within the ceramic case 130 via the space 86 and / or the protrusions 102 and is thus relative to the ceramic case 130 Does not translate or rotate.

Continuing to refer to FIG. 7, the embedded casting program 94 further includes a seventh step 138, that is, pre-heating the ceramic shell 130, and an eighth step 142, that is, pouring molten material (i.e., metal) into the ceramic shell 130 (like Through the opening in the cone). The molten material will constitute at least a portion of the golf club head body 14. This selected preheating temperature is based on, for example, the material used for the golf club head body 14. During the eighth step 142, the molten material is at least partially embedded in the HDMP 66, and when the molten material is cooled and solidified, the HDMP 66 becomes the final cast of the golf club head body 14 The whole part.

In some constructions, the molten material is a stainless steel alloy, aluminum alloy, titanium alloy, or other low density, high strength metal, but other constructions may include different materials. In some constructions, the molten material is polymer plastic, thermoplastic, thermoset plastic, or other similar materials. Similar materials may be pre-melted and poured into the ceramic shell 130. In some constructions, the molten material is a steel material (i.e., 17-4 PH stainless steel, Nitronic 50 stainless steel, martensitic steel, or other types of stainless steel), titanium-based materials such as Ti-9S and Ti-6-4 Materials, aluminum-based materials (such as high-strength aluminum alloys or composite aluminum alloys plated with high-strength alloys), or any combination of these. The HDMP 66 may have a higher melting point than the molten material, so that the HDMP 66 does not melt or deform when it comes into contact with the molten material constituting the golf club head body 14.

That is, as mentioned above, using the two protrusions 102 with the axes 106, 108 displaced relative to each other can prevent or block the HDMP 66 from being translated or rotated (ie, such as twisted) relative to the ceramic shell 130 during the process 94. In particular, the density of the molten material and the kinetic energy conferred by gravity and / or centrifugal motion tend to produce a force on the HDMP 66 during the eighth step 142. The protrusions 102 can advantageously resist this force and hold the HDMP66 in place, so that the HDMP 66 can be accurately positioned, while the center of gravity or CG 52 obtained is not adversely affected. In the same or other constructions, the interval 86 may inhibit or prevent the HDMP 66 from translating along or in the x or y axis direction. In addition, the interval 86 may inhibit or prevent the HDMP 66 from rotating about the z-axis. The interval 86 may replace the two protrusions 102 or be added in addition to the protrusions 102.

Continuing to refer to FIG. 7, the embedded casting program 94 further includes a ninth step 146, that is, removing the ceramic shell 130. The ceramic shell 130 can be removed, for example, by physically breaking the ceramic shell 130 after the molten metal has cooled, causing the ceramic shell 130 to break and fall from the cooling metal and leave the HDMP 66. In some constructions, the ceramic shell 130 may be removed by mechanical means such as vibration, impact, sand bombardment, or fine tooling.

Continuing to refer to FIG. 7, the embedded casting program 94 further includes a tenth step 150, that is, separating the cast components from the larger components of the cast components. For example, can be plural Casting components, such as the aforementioned one or more golf club head bodies 14 and HDMP 66, to form the golf club head 10, a series of golf club heads 10, and / or one or more golf club heads overall. Once all of these cast parts have been produced, they can be separated for further processing as described above. In the eleventh step 154, all cuts and pouring holes of each cast part are removed.

FIG. 11 illustrates one of the golf club head body 14 and the HDMP 66 after the tenth step 150. After the ceramic shell 130 is removed, the first surface 78 and the two protrusions 102 are exposed along the outside of the golf club head 10 and the golf club head body 14. The HDMP 66 is rigidly held and positioned and cast into the golf club head body 14, and the space 86 is formed between the HDMP 66 and the golf club head body 14.

Referring to FIGS. 7 and 11, the embedded casting program 94 further includes a twelfth step 158, that is, removing the two protrusions 102. The two protrusions 102 may be removed, for example, by grinding away the protrusions 102 toward the first surface 78 and then polishing the first surface 78 until the first surface 78 is smooth. Other constructions include removing the protrusions 102 in different ways, including laser removal, machining, and electrical discharge machining (EDM). The presence of the interval 86 facilitates the removal of the protrusions 102 without having to worry about the separation treatment of the golf club head body 14.

Referring to FIG. 7, the embedded casting program 94 further includes a thirteenth and final step 162, that is, the completion of the cast components or parts. For example, referring to FIG. 6, once the protrusions 102 are removed, the space 86 is filled to fill the material 90 (ie, such as paint, resin, rubber, silicone, or other elastic materials).

Without the gap 86 and / or without the filler material 90, the HDMP 66 and the height The golf club head body 14 may touch another person along the outside of the golf club head body 14, that is, along the exposed surface that can be seen by the user. Contact at the joint between the golf club head body 14 and the HDMP 66 may cause materials (ie, metals) located within this range to decolorize in an undesired manner. For example, the joint of the HDMP 66 and the golf club head body 14 along the exterior of the golf club head body 14 is generally hotter than the rest of the golf club head body 14 for at least a period of time It will be so. This temperature difference may cause a visually undesirable appearance at the joint due to oxidation between the HDMP 66 and the material of the golf club head body 14. The interval 86 is generated, and the filling material 90 is used, thereby providing a way to separate the first surface 78 of the HDMP 66 from the golf club head body 14 within this range, while along the completed golf ball. The outer surface of the club head 10 blocks and / or hides any decolorization. In addition, the interval 86 may inhibit or prevent the HDMP 66 from being translated along or in the x or y axis relative to the ceramic shell 130 during the casting process 94. Also, the interval 86 may inhibit or prevent the HDMP 66 from rotating along the z-axis relative to the ceramic shell 130 during the casting process 94.

The aforementioned embedded casting procedure 94 may advantageously locate the center of gravity or CG 52 of the golf club head 10. For example, the HDMP 66 has a higher density than the molten material constituting the golf club head body 14. Therefore, when the HDMP 66 is cast into the golf club head body 14, the HDMP 66 will cause the center of gravity or the CG 52 to move to a desired position (such as a lower, rearward position, that is, As shown in Figure 3). In some constructions, the HDMP 66 is sufficiently heavy to occupy a total mass between 1/7 and 1/9 of the golf club head 10 after casting and positioning, but in other constructions may include different values and ranges.

The aforementioned embedded casting program 94 can also advantageously maximize the HDMP 66 Lower, backwards. For example, the embedded casting program 94 can move the center of gravity or CG 52 farther down and backward than the HDMP setting method currently used. In addition, the embedded casting program 94 can minimize the support structure near the HDMP 66. This allows the unused weight in this support structure to be redistributed to other locations. The embedded casting program 94 can also eliminate welding, brazing, swaging, adhesive coating, drilling and drilling, and other time- and labor-intensive operations. The embedded casting program 94 also provides a higher degree of design freedom for the HDMP 66 setting than other methods used to join the HDMP to the club head body and often face many limitations in setting processing.

That is, as mentioned above, the HDMP itself may have various shapes and sizes, and may have various numbers, sizes, and shapes of protrusions. For example, FIGS. 12 and 13 illustrate a club head 210 and HDMP 266 according to another configuration. The HDMP 266 is made of tungsten, tantalum, hafnium, osmium, iridium or platinum, but other constructions may contain different materials. The HDMP 266 includes a first flange 270 and a second flange 274. The first and second flanges 270, 274 define a groove 278 that extends around at least a portion of the periphery of the HDMP 266. That is, as shown in FIG. 12, once the HDMP 266 has been cast using the embedded casting program 94, a part of a club head body 214 on the club head 210 extends into the groove 278. Utilizing the groove 278 can provide additional support and further assist in securing the HDMP 266 to the golf club head body 214. That is, as shown in FIG. 13, a space 286 is also provided for inserting a filling material, that is, similar to the space 86 described above, so the decolorization is prohibited or prevented. Further, similar to the interval 88, the interval 286 may inhibit or prevent the HDMP 266 from being translated along or in the x or y axis relative to the ceramic shell 130 during the casting process 94. At the same time, the interval 286 can inhibit or prevent the HDMP 266 from rotating about the z-axis relative to the ceramic shell 130 during the casting process 94.

14 and 15 illustrate an HDMP 366 constructed according to yet another. The HDMP 366 is made of tungsten, tantalum, hafnium, osmium, iridium or platinum, but other constructions may contain different materials. The HDMP 366 contains protrusions 370 that extend from the surface 374 (ie, as vertically). The protrusion 370 is a non-cylindrical protrusion, and has a substantially triangular cross section, but other structures may include different cross sections, including a square, a hexagon, and the like. The protrusion 370 includes a first end 378 located at the surface 374, opposite to the first end 378 and away from the second end 382 of the surface 374, and disposed along one side of the protrusion 370 and A notch 386 is located between the first and second ends 378, 382. The notch 386 defines all the extents on the protrusion 370. In some constructions, the notch 386 is a semi-circular or other shaped element cut from the protrusion 370. Referring to FIG. 14, the notch 386 has a notch length “NL” measured in a direction “Z” as defined by the protrusion 370. The notch length "NL" is at least 0.005 inches, but other configurations may include different values and ranges. For example, in some constructions, the notch length "NL" is at least 0.0075 inches. In some constructions, the notch length "NL" is at least 0.010 inches. In some constructions, the notch width "NW" measured by the notch along a direction perpendicular to the notch length "NL" is at least 0.005 inches, although other values and ranges are also possible. For example, in some constructions, the notch width "NW" is at least 0.0075 inches. In some constructions, the notch width "NW" is at least 0.010 inches.

The function of the single protrusion 370 is similar to the combination of the two protrusions 102 described above. For example, during the embedded casting process 94, the protrusion 370 is at least partially embedded in the ceramic shell 130. Due to the non-cylindrical shape of the protrusion 370, compared to a single cylindrical protrusion, the protrusion 370 is less likely to slide out of the ceramic shell 130 or translate or rotate relative to the ceramic shell 130 (i.e. Twist). In addition, the notch 386 is provided for further grasping the ceramic On the case 130, the protrusion 370 is thus prohibited or prevented from being translated or rotated (ie, twisted) relative to the ceramic case 130 (like moving from the direction "Z" shown in FIG. 14). The notch 386 can be separated from the sealing wax 118 during the embedded casting process 94 (such as being provided from the outer surface of the sealing wax 118), and can receive the ceramic material constituting the ceramic shell 130. In some constructions, the non-cylindrical protrusion 370 is provided with more than one notch 386. In some constructions, the non-cylindrical protrusion 370 does not contain a notch 386. In some constructions, the notch 386 is positioned along the protrusion 370 at a different position from that shown in the figure (ie, as at the second end 382). In the same or other constructions, an interval similar to the interval 86 can be used to inhibit or prevent the HDMP 366 from translating along or in the x or y axis direction. In addition, this interval can inhibit or prevent the HDMP 366 from rotating around the z-axis. The interval may replace the protrusion 370 and / or the notch 386, or be added in addition to the protrusion 370 and / or the notch 386.

FIG. 16 illustrates HDMP 466 constructed according to yet another construction and cast into material 468 (eg, 17-4 stainless steel). The HDMP 466 is made of tungsten, tantalum, hafnium, osmium, iridium, or platinum, but other constructions may contain different materials. The HDMP 466 contains a cylindrical protrusion 470, which extends from the surface 474 (ie, vertically) of the base portion 476 (shown schematically in FIG. 16), and in some constructions the HDMP 466 also contains, for example, a flange 74 similar to the aforementioned Of the flange). The protrusion 470 includes a first end 478 located at the surface 474 and a second end 482 opposite to the first end 478 and remote from the surface 474. The cylindrical projection 470 also contains a notch 486. The notch 486 is provided along the side of the protrusion 470 at the second end 482. The notch 486 defines a range of cuts on the protrusion 470. Similar to the notch 386, the notch 486 is available to be gripped on the ceramic shell 130 during the embedded casting process 94, and the HDMP 466 is prohibited or prevented from translation or rotation relative to the ceramic shell 130 (i.e. (Such as twisting). In the same or other constructions, An interval similar to the interval 86 to inhibit or prevent the HDMP 466 from translating along or in the x or y axis direction. In addition, the interval can inhibit or prevent the HDMP 466 from rotating around the z-axis. The interval may replace the protrusion 470 and / or the notch 486, or be added in addition to the protrusion 470 and / or the notch 486. In some constructions, the protrusion 470 contains more than one notch 486. In some constructions, more than one protrusion 470 is provided, at least one of which contains a notch 486. The notch 486 defines a range of cuts on the protrusion 470. In some constructions, the notch 486 cuts a semi-circular or other shaped element from the second end 482 of the protrusion 474. The notch has a notch length "NL1" measured in a direction "Z1" defined by the protrusion 470. The notch length "NL1" is 0.005 inches, but other constructions may contain different values and ranges. For example, in some constructions, the notch length "NL1" is at least 0.0075 inches. In some constructions, the notch length "NL1" is at least 0.010 inches. In some constructions, the notch width "NW1" measured at a direction perpendicular to the notch length "NL1" is at least 0.005 inches, although other values and ranges are also possible. For example, in some constructions, the notch width "NW1" is at least 0.0075 inches. In some constructions, the notch width "NW1" is at least 0.010 inches.

17 and 18 illustrate a HDMP 566 constructed according to yet another. The HDMP 566 is made of tungsten, tantalum, hafnium, osmium, iridium, or platinum, although other constructions may contain different materials. Similar to HDMP 66, the HDMP 566 contains a base portion 570, a flange 574, a first surface 578 on the base portion 570, and an opposite, second surface 582 on the flange 574. The HDMP 566 also contains protrusions 586, which extend from the first surface 578 (ie, as vertically). The protrusion 586 is a long stick. That is, as shown in FIG. 18, during the embedded casting process 94, the protrusion 586 is embedded in the ceramic shell 130. Since the protrusion 586 is a long rod, the HDMP 566 is prohibited or prevented from being translated or rotated (ie, such as twisted) relative to the ceramic shell 130. in In some constructions, the HDMP 566 contains more than one protrusion 586. In some constructions, the protrusion 586 contains one or more notches (such as notch 386 or notch 486). In the same or other constructions, an interval similar to the interval 86 can be used to inhibit or prevent the HDMP 566 from translating along or in the x or y axis direction. In addition, this interval can inhibit or prevent the HDMP 566 from rotating around the z-axis. The interval may replace the protrusion 586 or be increased in addition to the protrusion 586.

FIG. 19 illustrates a HDMP 666 according to yet another construction. The HDMP 666 contains at least one extended penetration 670. In the construction, the HDMP 666 contains two perforations 670, but other constructions may contain different numbers and arrangements of perforations 670. For example, in some constructions, the HDMP 666 contains a single perforation 670. In some constructions, the HDMP 666 contains more than two perforations 670. In the construction, the perforations 670 are cylindrical and have a fixed diameter. In some constructions, the perforations 670 may have a varying diameter. The perforations 670 are exposed to the flow of molten material (ie, such as metal) during the embedded casting process 94. Thus, the perforations 670 can provide openings through which the molten material (ie, metal) can flow in during the embedded casting process 94. When the molten material is cooled and solidified, the HDMP 666 is supported and held by the solidified material in the perforations 670.

20 and 21 illustrate an HDMP 766 constructed according to yet another alternative. The HDMP 766 contains at least one external surface 770 and at least one depression 774 (ie, such as a blind hole) provided on the at least one external surface 770. In the construction, the HDMP 766 contains twenty-one depressions 774 disposed on five different external surfaces 770, but other constructions may contain different numbers and arrangements of depressions 774. For example, in some constructions the HDMP 766 contains more than one depression 774 disposed only on a single external surface 770. In some constructions, the HDMP 766 contains a single depression 774 on a plurality of different external surfaces 770. In the construction, the depressions 774 are Cylindrical and has a fixed diameter. In some constructions, the depressions 774 may have a varying diameter. In some constructions, the depressions 774 are bowl-shaped, pyramidal, or other shapes to provide a recessed area or range discontinuous from the surface 770. The depressions 774 are exposed to the flow of molten material (ie, such as metal) during the embedded casting process 94. As such, the depressions 774 can provide openings through which the molten material can flow during the embedded casting process 94. When the molten material is cooled and solidified, the HDMP 766 is supported and held by the solidified material in the depressions 774.

In some constructions, the HDMP contains both at least one perforation 670 and at least one depression 774. In some constructions, the HDMP includes at least one protrusion (ie, protrusion 102, 370, 470, or 580 as described above), and at least one perforation 670 and / or at least one depression 774. In some constructions, HDMP has a surface so formed. In some constructions, HDMP has a surface that is processed to a desired roughness. In some constructions, the HDMP has a coating that is applied to enhance the adhesion of the sealing wax 118 and / or the ceramic shell 130 during the aforementioned embedded casting process 94. In some constructions, the HDMP contains at least two different protrusions (ie, protrusion 102 and protrusion 370). In some constructions, the golf club head contains more than one HDMP that is positioned using the aforementioned embedded casting program 94.

FIG. 22 illustrates another embedded casting process 1094 for constructing the golf club head 10 and for coupling the HDMP 866 to the golf club head body 14 shown in FIGS. 1-6. The embedded casting program 1094 illustrated in FIG. 22 is similar in many respects to the embedded casting program 94 described in FIG. 7 except that the embedded casting program 1094 shown in FIG. 22 lacks the inclusion of removing the HDMP projections from the part. Out of steps. The embedded casting program 1094 includes a first step 1098, which constitutes the HDMP 866. The HDMP 866 is produced by, for example, machining, It is made by casting, metal injection molding, direct laser sintering, powder metal forming procedures, or other appropriate processing methods known to those skilled in the art.

Referring to FIG. 23, the HDMP 866 is similar to the HDMP 66, except that the HDMP 866 lacks any protrusions extending from the first surface 878 of the HDMP 866 base portion 870, which is different from the protrusions of the first surface 78 of the HDMP 66 102. However, the HDMP 866 does contain a single projection 802 extending from the second surface 882 of the HDMP 866, as shown in FIG. The protrusion 802 may extend from the second surface 882 of the HDMP 866 (ie, as vertically), and may be integrally formed as a part of the HDMP 866. In the construction, the protrusion 802 extends between 0.2 and 10 inches from the second surface 882, but other constructions may include different values and ranges. In some constructions, the protrusion 802 extends from the second surface 882 between 0.2 and 1 inch. In some constructions, the protrusion 802 extends from the second surface 882 between 0.2 and 5 inches. In some constructions, the HDMP 866 may not include any protrusions 802. In some constructions, the HDMP 866 may contain a plurality of protrusions 802.

The protrusion 802 also has a cross-sectional area. In the construction, the protrusion 802 has a circular cross section, which defines a cross-sectional area of 0.005 square inches to 0.010 square inches, but other constructions may contain different values and ranges. In some constructions, the protrusion 802 has a cross-sectional area of 0.005 square inches to 0.015 square inches. In some constructions, the protrusion 802 has a cross-sectional area of about 0.005 square inches. In some constructions, the cross-sectional area approaches or equals the area of the first surface 878. In addition, other constructions may include protrusions 802 with different cross sections, including triangles, squares, hexagons, and so on.

In some constructions, after forming the HDMP 866, a coating may be applied to the HDMP 866, which may protect the HDMP 866 during subsequent steps of the embedded casting process 1094 HDMP 866. In many constructions, the coating can preserve the structural integrity of the HDMP 866 by preventing oxidation during subsequent casting processes, as described in further detail below. The coating may be made of any material sufficient to withstand high temperatures, ie as previously discussed. For example, the coating may be made of ceramic, metal, alloy ceramic, silicone, silicon salt, or any other material or combination of materials that can withstand high temperatures. Exemplary alloy ceramic coatings may include, but are not limited to, tungsten carbide-cobalt, chromium carbide-nickel chromium, oxide ceramics, such as chromium oxide and aluminum oxide, molybdenum, iron, and nickel. Exemplary metal coatings may include, but are not limited to, tungsten carbide powder, nitride powder, zirconia, diamond powder, cerium oxide, and alumina. Further, the coating can be applied using any procedure, such as, for example, chemical vapor deposition, thermal spraying, or painting. In some constructions, the thickness of the coating can range from 25 micro-inches to 400 micro-inches. In some constructions, a second coating can be applied on the first coating, and the thickness of the second coating can range from 5 microinches to 60 microinches.

Referring to FIGS. 22, 24 and 25, the embedded casting program 1094 further includes a second step 1110, that is, placing the HDMP 866 in a sealing wax injection mold, and a third step 1114, that is, sealing wax 818 (such as a coating sealing wax) ) Is injected into the sealing wax injection mold, so that the HDMP 866 is partially embedded in a wax shell or sheath. The sealing wax injection mold can create a gap 886 between the outer surface of the base portion 870 and the sealing wax 818. The outer surface of the base portion 870 is part of the HDMP 866, and this will be exposed to the outside of the golf club head 10 after the embedded casting process 1094 is completed. In many constructions, the space 886 may extend completely around the base portion 870. In some constructions, the space 886 may extend partially around the base portion 870. In other constructions, the interval 886 may contain one or more portions extending at least partially around the base portion 870, thus generating a plurality of interval segments. For example, referring to FIG. 30, the interval may contain a single first interval portion 87 which is about the base portion 70 approximately Extend in half. For a further example, referring to FIG. 31, the interval 86 may include a first interval portion 87 disposed at a corner 71 of the base portion 70, and a second interval portion 88 disposed at a second corner 72 of the base portion 70. A third spaced portion 89 at the third corner 73 of the base portion 70 and a fourth spaced portion 91 provided at the fourth corner 75 of the base portion 70. For a further example, referring to FIG. 32, the interval 86 may include a first interval portion 87 disposed at a left side 92 of the base portion 70, and a second interval portion 88 disposed at a right side 93 of the base portion 70. For a further example, referring to FIG. 32, the interval 86 may include a first interval portion 87 disposed at the front side 95 of the base portion 70 and a second interval portion 88 disposed at the rear side 96 of the base portion 70. In other examples, the interval 86 may contain any combination of the aforementioned interval segments and locations.

For example, and referring to FIG. 24, in the construction, the tool 820 is disposed adjacent to the HDMP 866. The tool 820 contains a first plate 825 and a second plate 826. The first plate 825 includes a lip 821 which is configured to receive at least a portion of a base portion 870 of the HDMP 866. In many configurations, the lip 821 receives the entire base portion 870. In some constructions, the lip 821 can receive a portion of the base portion 870. In other constructions, the lip 821 can receive the entire base portion 870 and a portion of the top portion 867. The second plate 826 contains at least one hole 803, which is configured to receive the protrusion 802 of the HDMP 866 (FIG. 24 is a schematic representation of the HDMP 866 and the tool 820, and only shows a single protrusion 802 And the holes 803; however, as previously mentioned, the HDMP 866 may have two or more protrusions 802 and the tool 820 may have two or more holes 803). In many constructions, the lip 821 may extend completely around the periphery of the HDMP 866. In some constructions, the lip 821 may extend partially around the periphery of the HDMP 866. In other constructions, the lip 821 may contain There are one or more parts extending at least partially around the perimeter of the HDMP 866. The lip 821 includes a lip height "LH" extending from the flat plate 825 toward the HDMP 866. In the configuration, the lip height "LH" is between 0.01 inch and 1 inch, although other values and ranges are also possible. For example, in some constructions, the height of the lip 821 is between 0.01 and 1.5 inches. In some constructions, the height of the lip 821 may be 0.01, 0.05, 0.1, 0.15, 0.2, 0.25, 0.3, 0.35, 0.4, 0.45, 0.5, 0.55, 0.6, 0.65, 0.7, 0.75, 0.8, 0.85, 0.9 , 0.95, 1.0, 1.05, 1.1, 1.15, 1.2, 1.25, 1.3, 1.35, 1.4, 1.45 and 1.5 inches. Further, the lip 821 includes a lip width “LW” extending in a direction parallel to the flat plate 825 and perpendicular to the height direction of the lip. In the specific embodiment, the lip width "LW" is between 0.01 inch and 1 inch, but other values and ranges are also possible. For example, in some constructions, the width of the lip 821 is between 0.01 and 1.5 inches. In some constructions, the width of the lip 821 may be 0.01, 0.05, 0.1, 0.15, 0.2, 0.25, 0.3, 0.35, 0.4, 0.45, 0.5, 0.55, 0.6, 0.65, 0.7, 0.75, 0.8, 0.85, 0.9 , 0.95, 1.0, 1.05, 1.1, 1.15, 1.2, 1.25, 1.3, 1.35, 1.4, 1.45 and 1.5 inches. Further, in the construction, the lip 821 has a rectangular cross section. In other constructions, the lip 821 may take other cross-sectional shapes. For example, the lip 821 may be triangular, cylindrical, pyramidal, spherical, cubic, or any suitable cross-sectional shape.

When the sealing wax 818 is injected into the tool 820, the sealing wax 818 surrounds at least a part of the HDMP 866 to form a wax shell and a sheath, as shown in FIG. This procedure allows the HDMP 866 to be embedded at least partially within the sealing wax 818 in a precise and repeatable manner. That is, as shown in FIG. 25, the sealing wax 818 is at least partially embedded in the flange 874 and the top side part 867, but the base part 870 and the protrusion 802 are left as exposed or set in (projected Out) The sealing wax 818 is external. In some constructions, only a portion of the base portion 870 may be exposed outside the sealing wax 818. In other constructions, the entire base portion 870 and a portion of the top side portion 867 may be exposed outside the sealing wax 118.

22 and 25, the embedded casting program 1094 further includes a fourth step 1122, that is, adding a wax sealing element to the wax sealing equipment, and a fifth step 1126, that is, coating the wax sealing equipment with ceramic material. That is, as shown in FIG. 25, for example, the sealing wax 818 forms at least one wax element for the sealing wax component of the golf club head 10. In some constructions, the sealing wax assembly has a main sealing wax body. Each wax sealing element is an integral sealing wax component attached to the main sealing wax body for constituting the golf club head body 14. In some constructions, a cone or cup (not shown) can be attached to the wax seal assembly on the top side of the wax seal assembly. This cone contains an opening through which molten material can be poured during later steps.

During the fifth step 1126, the sealing wax component can be immersed in a liquid ceramic slurry, thereby forming a ceramic shell 830 on the sealing wax component (FIG. 25). The wax sealing assembly is provided with a plurality of ceramic coatings to constitute the ceramic shell 830, because the plurality of ceramic coatings can reach a desired strength enough to be held in a later step of pouring molten material into the ceramic shell 830. Molten material. Each coating is dried before the next coating is applied. That is, as shown in FIG. 25, during this step, the HDMP 866 is at least partially embedded in the combination of the sealing wax 818 and the ceramic case 830, and the protrusion 802 is set in the ceramic case 830. However, the protrusion 802 does not penetrate the ceramic shell 830 and the space 886, and the space is generated by the lip 821, and contains a part of the base part 870 and is formed of the ceramic material of the ceramic shell 830 Occupied.

Referring to FIG. 22 again, the embedded casting program 1094 further includes a sixth step 1134, that is, melting and removing the sealing wax 818. In the construction, the ceramic shell 830 is dried Thereafter, the sealing wax component 818 can be melted by turning the sealing wax component and heating the sealing wax component. During the sixth step 834, and as further detailed later, the HDMP 866 is rigidly held in the ceramic case 830 by the protrusion 802 and the ceramic filling interval 886; the protrusion 802 can prevent relative The ceramic case 830 is translated along or in the z-axis direction, and the interval 886 prevents translation relative to the ceramic case 830 in or in the x or y axis direction and prevents rotation about the z axis. A hollow area is formed between the ceramic case 830 and the HDMP 866. Continuing to refer to FIG. 22, the embedded casting program 1094 further includes a seventh step 1138, that is, heating the ceramic shell 830 in advance, and an eighth step 1142, that is, pouring molten material (ie, metal) into the ceramic shell 830 (like Via the opening in the aforementioned pyramid). The molten material will constitute at least a portion of the golf club head body 14. This selected preheating temperature is based on, for example, the material used for the golf club head body 14. During the eighth step 1142, the molten material will be at least partially embedded in the HDMP 866, and when the molten material is cooled and solidified, the HDMP 866 will become the final casting of the golf club head body 14 The whole part.

In some constructions, the molten material is a stainless steel alloy, aluminum alloy, titanium alloy, or other low density, high strength metal, but other constructions may include different materials. In some constructions, the molten material is a polymer plastic, a thermoplastic plastic, a thermosetting plastic, or other similar materials that can be hot melted and poured into the ceramic shell 830. In some constructions, the molten material is a steel material (i.e., 17-4 PH stainless steel, Nitronic 50 stainless steel, martensitic steel, or other types of stainless steel), titanium-based materials such as Ti-9S and Ti-6-4 Materials, aluminum-based materials (such as high-strength aluminum alloys or composite aluminum alloys plated with high-strength alloys), or any combination of these. The HDMP 866 may have a higher melting point than the molten material, so that the HDMP 866 does not melt or deform when it comes into contact with the molten material constituting the golf club head body 14.

That is, as mentioned above, using the protrusion 802 and the interval 886 can inhibit or prevent the HDMP 866 from being translated or rotated with respect to the ceramic shell 830 during the embedded casting process 1094. In particular, the density of the molten material and the kinetic energy conferred by gravity and / or centrifugal motion tend to produce a force on the HDMP 866 during the eighth step 1142. The protrusion 802 and the interval 886 can advantageously resist this force and hold the HDMP 866 in place, so that the HDMP 866 can be accurately positioned, and at the same time, the obtained center of gravity or CG 52 is not adversely affected.

Continuing to refer to FIG. 22, the embedded casting program 1094 further includes a ninth step 1146, that is, removing the ceramic shell 830. The ceramic shell 830 may be removed, for example, by physically breaking the ceramic shell 830 after the molten metal has cooled, causing the ceramic shell 830 to break and fall from the cooling metal and leave the HDMP 866. In some constructions, the ceramic shell 830 may be removed by mechanical means such as vibration, impact, sand bombardment, or fine tooling.

Continuing to refer to FIG. 22, the embedded casting program 1094 further includes a tenth step 1150, that is, separating the cast parts from the larger components of the cast parts. For example, the golf club head 10, a series of golf club heads 10, and / or one or more may be formed from a plurality of cast parts, such as the aforementioned one or more golf club head bodies 14 and HDMP 866. Multiple golf club heads overall. Once all of these cast parts have been produced, they can be separated for further processing as described above. In the eleventh step 1154, all cuts and pouring holes of each cast part are removed.

FIG. 26 illustrates one of the golf club head body 14 and the HDMP 866 after the tenth step 1150. After the ceramic shell 830 is removed, the first surface 878 and the space 886 are exposed along the outside of the golf club head 10 and the golf club head body 14. The HDMP 866 is rigidly held and positioned and cast into the golf club head body 14, The interval 886 is formed between the HDMP 866 and the golf club head body 14.

Referring to FIG. 22, the embedded casting program 1094 further includes a twelfth and final step 1162, that is, the completion of the cast components or parts. For example, and referring to FIG. 6, the space 886 is filled with a filling material 90 (ie, such as paint, resin, rubber, silicone, or other elastic material). In many constructions, the twelfth step of the embedded casting program 94 shown in FIG. 7 is not required, which includes removing the protrusion 102 from the first surface 78 of the HDMP 66, because the embedded casting program The HDMP 866 protrusion 802 used in 1094 is provided inside the club head 14.

Without the interval 886 and / or the filler material 90, the HDMP 866 and the golf club head body 14 may be along the outside of the golf club head body 14, that is, along the exposure visible to the user. Out of the surface and touch the other. Contact at the junction between the golf club head body 14 and the HDMP 866 may cause materials (ie, metals) located within this range to decolorize in an undesired manner. For example, the joints of the HDMP 866 and the golf club head body 14 along the exterior of the golf club head body 14 are generally hotter than the rest of the golf club head body 14 for at least a period of time It will be so. This temperature difference may cause a visually undesirable appearance at the joint due to oxidation between the HDMP 866 and the material of the golf club head body 14. The interval 886 is generated, and the filling material 90 is used, thereby providing a way to separate the first surface 878 of the HDMP 866 from the golf club head body 14 within this range, while along the completed golf ball. The outside of the club head 10 blocks and / or hides any decolorization. In addition, the interval 886 can inhibit the HDMP 866 from translating with respect to the ceramic shell 830 along or in the x or y direction and avoid rotating around the z axis during the casting process 1094.

The embedded casting program 1094 shown in FIG. 22 can be used to construct HDMP 866 club head 10. The aforementioned embedded casting procedure 1094 can advantageously locate the center of gravity or CG52 of the golf club head 10. For example, the HDMP 866 has a higher density than the molten material constituting the golf club head body 14. Therefore, when the HDMP 866 is cast into the golf club head body 14, the HDMP 866 moves the center of gravity or the CG 52 to a desired position (such as a lower, rearward position, that is, As shown in Figure 3). In some constructions, the HDMP 866 is sufficiently heavy to occupy a total mass between 1/7 and 1/9 of the golf club head 10 after casting and positioning, but may include different values and ranges in other constructions.

The aforementioned embedded casting program 1094 can also advantageously maximize the lower, rearward positioning of the HDMP 866. For example, the embedded casting program 1094 can move the center of gravity or CG 52 farther down and backward than the HDMP setting method currently used. In addition, the embedded casting program 1094 can minimize the support structure near the HDMP 866. This allows the unused weight in this support structure to be redistributed to other locations. The embedded casting program 1094 can also eliminate welding, brazing, swaging, adhesive coating, drilling and drilling, and other time-intensive operations. Compared with other methods for joining HDMP to the club head body and usually facing many limitations in the setting process, the embedded casting program 1094 can also provide a higher degree of design freedom for the setting of the HDMP 866.

In addition, the HDMP 866 and the embedded casting program 1094 may be advantageous because they do not need to remove the protrusions from the HDMP 866. This step is not needed because the protrusion 802 extends inwardly relative to the club head 14 to avoid translation along or in the z-axis direction, and the interval 886 prevents along or toward the x or y axis The directional translation also prevents rotation around the z-axis, so that the HDMP 866 can be held in place during the casting process.

Figures 27, 28, and 29 illustrate HDMP 966 according to yet another configuration. The HDMP 966 is made of tungsten, tantalum, hafnium, osmium, iridium, or platinum, although other constructions may contain different materials. The HDMP 966 is similar to the HDMP 66, except that the HDMP 966 lacks any protrusions, as shown in FIG. 27. The club head 10 having the HDMP 966 can be configured using an embedded casting program 1094 shown in FIG. 22.

Referring to FIG. 27, a tool 920 for sealing wax injection according to a third step 1114 includes a first plate 925 and a second plate 926. The tool 920 is similar to the aforementioned tool 820, except that the hole 903 of the second flat plate 926 includes a cylindrical wall portion 927, the wall portion is directed inward from the second flat plate 925 toward the first flat plate 925, or It extends towards the second surface 982 of the HDMP 966. In the specific embodiment, the height (AH) of the cylindrical wall portion 927 (that is, in a direction extending toward the first flat plate 925) is between 0.01 inches and 1.5 inches, but other values and Range is also possible. For example, in some constructions, the height of the hole may be 0.01, 0.05, 0.1, 0.15, 0.2, 0.25, 0.3, 0.35, 0.4, 0.45, 0.5, 0.55, 0.6, 0.65, 0.7, 0.75, 0.8, 0.85, 0.9 , 0.95, 1.0, 1.05, 1.1, 1.15, 1.2, 1.25, 1.3, 1.35, 1.4, 1.45 and 1.5 inches. Further, in the specific embodiment, the hole 903 has a rectangular cross section. In other specific embodiments, the hole 903 may be triangular, pyramidal, spherical, cubic, or any other suitable cross-sectional shape.

When the sealing wax 918 is injected into the tool 920, the sealing wax surrounds at least a part of the HDMP 966, that is, similar to when the sealing wax is injected into the tool 820, except that the tool 920 generates a hole 903. In addition, the hole penetrates the thickness of the sealing wax 918 to the second surface 982 of the top-side part 967 of the HDMP 966. In this way, a part of the second surface 982 can be exposed to the outside for performing the fifth step 1126. A fifth step 1126 includes applying the ceramic shell 930 to the HDMP 966. The hole 903 contains a ceramic material for forming the ceramic shell. And via the sealing wax 918 adjacent to the second surface 982 of the HDMP 966, a ceramic post 904 is generated (FIG. 28). During the sixth step 1134, this involves melting out the sealing wax, and the ceramic pillar 904 adjacent to the second surface 982 is the same as the ceramic shell provided on the first surface 978 of the HDMP 966. 930 local, can prevent the HDMP 966 from moving in the direction of or toward the z axis.

In other embodiments, the tool 920 may generate a plurality of holes. The functions of these holes are similar to holes 903, because each of them contains a ceramic material used to form the ceramic shell and generates a plurality of ceramic posts. For example, in some embodiments, the tool 920 can be configured to generate one, two, three, four, five, or six holes 903 to receive the ceramic material used to form the ceramic shell and generate a plurality of ceramic posts. column. Each ceramic post extends through a sealing wax 918 adjacent to the second surface 982 of the HDMP 966. During the sixth step 1134, this involves melting out the sealing wax, and the ceramic post adjacent to the second surface 982 is the same as the ceramic shell provided on the first surface 978 of the HDMP 966. 930 local, it can prevent the HDMP 966 from moving in the z-axis direction. In other embodiments, the tool 920 can be configured to generate any number of holes similar to the holes 903. In some embodiments, the holes may be separated by a fixed distance. In other embodiments, the holes may be spaced at irregular distances. In some embodiments, each hole may have the same cross-sectional size. In other specific embodiments, each hole may have a different cross-sectional size.

Referring to FIGS. 28 and 29, the HDMP 966 and the club head body 14 collectively form an interval 986 between the base portion 970 and the golf club head body 14 along the outside of the golf club head 10. .
