Description

Technical Field

[0001] The utility model relates to the technical field of golf head casting molds, in particular to a special-shaped golf head casting shell mold. Background Art

[0002] Golf head casting molds are key tools used to manufacture golf heads and are usually made of high-temperature resistant ceramics. The design of the mold usually includes the shape contours of the golf head, spherical grooves and other details to ensure that the final cast product meets the standards specified for golf balls. During the manufacturing process, the mold is filled with molten metal material, which is then cooled and solidified to form a complete golf head. The quality and precision of the mold directly affects the quality and performance of the final product.

[0003] Golf heads currently in use are usually manufactured using the lost wax method, where a mold of the golf head is first made using a plastic material (such as silicone) to replicate the external shape and details of the head. The mold is then filled with wax and allowed to cool and solidify to form a wax mold, which is then baked and treated with lost wax to form a cavity for pouring metal. After the metal cools and solidifies, the cast golf head can be taken out.

[0004] Most of the molds currently used for making golf heads are integrally formed. This shape and style of the mold can ensure the surface integrity of the golf head when making the golf head, but it is more complicated to demold. If the mold is made of ceramic, the ceramic mold will be damaged during demolding, thereby increasing the manufacturing cost of the golf head and being very inconvenient to use.

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Reference Figure 1-Figure 2The utility model provides an embodiment: a special-shaped ball head casting shell mold, including a base 1, both sides of the top of the base 1 are rotatably connected to a shell 2, the two shells 2 can be spliced ​​together to form a complete shell mold, and the material is cast between the two shells 2 and solidified, so that the casting operation of the golf head can be completed. A slide groove 4 is opened in the middle of the base 1, and a moving block 3 is slidably connected inside the slide groove 4. A connecting piece 6 is fixedly connected to the outside of the moving block 3. The other end of the connecting piece 6 is rotatably connected to a connecting rod 5. The other end of the connecting rod 5 is rotatably connected to the outside of the shell 2 through the connecting piece 6. The connecting rod 5 is acted on by the up and down movement of the moving block 3, and then after cooperating with the connecting piece 6, the two shells 2 can be unfolded and merged, so as to facilitate demoulding and casting operations. A threaded rod 7 is rotatably connected to the middle of the base 1, and the moving block 3 is threadedly connected to the outer periphery of the threaded rod 7. The moving block 3 can be driven to move up and down by rotating the threaded rod 7. A knob 8 is fixedly connected to the bottom of the threaded rod 7, and the knob 8 is used to rotate the threaded rod 7 with less effort;

[0034] Reference Figure 1-Figure 3 , an ejection assembly is installed on the top of the threaded rod 7, which is used to eject the ball head located inside the shell 2. The ejection assembly includes a threaded sleeve 16, which is threadedly connected to the top of the threaded rod 7. A top plate 17 is fixedly connected to the top of the threaded sleeve 16. When the threaded rod 7 rotates to transport the moving block 3 upward, the threaded sleeve 16 is driven to move upward, thereby driving the top plate 17 to move upward to eject the ball head located between the two shells 2, so as to further facilitate demolding. The top plate 17 is slidably connected to the bottom of the shell 2. A placement groove 18 is provided at the bottom of the shell 2. The top plate 17 is placed inside the placement groove 18. The position of the top plate 17 can be limited by the placement groove 18, so that when the top plate 17 is placed inside the placement groove 18, the integrity of the shell 2 can be guaranteed. At the same time, the placement groove 18 can also prevent the top plate 17 from shaking during movement;

[0035] Reference Figure 2-Figure 4The top of the shell 2 is fixedly connected with a rim 9, and a plurality of notches 10 are provided in the middle of the rim 9. The notches 10 and the rim 9 can reduce the overflow of materials during the casting process. The inner wall of the shell 2 is provided with a cavity 13, and the middle of the shell 2 is provided with a water inlet 11, and the water inlet 11 is connected with the cavity 13. After the casting is completed, the shell mold is placed in cold water, and the cold water will enter the cavity 13 from the water inlet 11 to carry the heat of the shell 2, thereby improving the cooling efficiency. The inner side of the shell 2 is fixedly connected with a heat insulation layer 12, and the heat is isolated by the heat insulation layer 12. Firstly, it can reduce the loss of heat during the casting process, and secondly, it can avoid burns when taking it. A heat-conducting layer 14 is provided on the inner side of the heat-insulating layer 12, and the cavity 13 is located between the heat-insulating layer 12 and the heat-conducting layer 14; the inner wall of the heat-conducting layer 14 is also fixedly connected to the inner cavity wall 15, and the ball head is in contact with the inner surface of the inner cavity wall 15. The heat during the casting process can be conducted to the inside of the cavity 13 through the heat-conducting layer 14 and the inner cavity wall 15, and the heat conduction speed can be increased when cold water cooling is performed.

[0036] Working principle: When in use, first splice the two shells 2, and then cast from the opening on the upper part of the shell 2. After casting, place the shell mold in cold water for cooling. At this time, cold water will enter the cavity 13 from the water inlet 11 to conduct heat, thereby improving cooling efficiency.

[0037] After cooling is completed, the shell mold is taken out, and then the threaded rod 7 is rotated by turning the knob 8. At this time, the moving block 3 will move upward along the slide groove 4 to push the connecting rod 5, so that the two shells 2 are unfolded along the top of the base 1. At the same time, the threaded sleeve 16 moves upward synchronously to push the top plate 17 out of the middle of the placement groove 18, so that the cast ball head can be ejected more conveniently.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
