Technical Field
[0001] The utility model relates to the technical field of golf club head casting molds, in particular to an ultra-thin top cover casting mold for a golf club head. Background Art
[0002] A golf club head casting mold is a key tool for manufacturing golf club heads and is usually made of high-temperature-resistant ceramics. The design of the mold generally includes the outer contour of the golf club head, spherical grooves, and other details to ensure that the finally 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 club head. The quality and precision of the mold directly affect the quality and performance of the final product.
[0003] The casting mold for a golf club head is manufactured by the lost wax casting method, which includes several key steps. First, a mold of the golf club head is made using a plastic material (such as silicone) to replicate the external shape and details of the club head. Then, wax is filled into the mold and allowed to cool and solidify to form a wax pattern. Subsequently, after baking and dewaxing, a cavity is formed for pouring metal. After the metal cools and solidifies, the cast golf club head can be taken out.
[0004] However, the currently used golf club head casting molds are often integrally formed. After casting is completed, the external ceramic shell needs to be broken to remove the club head, which reduces the service life of the mold and increases the production cost. In addition, the currently used casting molds cannot be cooled well, resulting in a long casting time. Therefore, an ultra-thin top cover casting mold for a golf club head is proposed to solve the above problems. Summary of the Utility Model
[0005] To make up for the above deficiencies, the utility model provides an ultra-thin top cover casting mold for a golf club head, aiming to improve the problems that the existing club head casting molds need to break the ceramic shell to remove the mold, have a high production cost, and cannot be quickly cooled, resulting in a long time consumption.

Detailed implementation manner
[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.
[0035] Referring to Figures 1-4 , an embodiment provided by the present invention: a thin-top casting mold for a golf ball head, including a bottom mold 1, a top mold 2 is rotatably connected to the bottom of the bottom mold 1, and one end of the bottom mold 1 and the top mold 2 is connected by a hinge. After connection, the bottom mold 1 and the top mold 2 form a complete mold for casting the golf ball head. A rod handle 5 is fixedly connected to the top of the top mold 2. After partial casting of the rod handle 5, the connecting part between the golf club and the ball head can be formed. A pouring gate 4 is opened in the middle of the bottom mold 1, and the material for casting is poured from the pouring gate 4. A bracket 9 is fixedly connected to the outside of the top mold 2, and a fixing part 7 is also fixedly connected to the outside of the bottom mold 1. A threaded rod 8 is rotatably connected to the middle of the fixing part 7. A nut 10 is threadedly connected to the outer circumference of the threaded rod 8. The nut 10 is located above the bracket 9. After closing the bottom mold 1 and the top mold 2, the threaded rod 8 is rotated along the fixing part 7 to carry the nut 10 to the upper part of the bracket 9, and then the nut 10 is screwed to make the nut 10 press downward and contact the top of the bracket 9, so as to lock the end of the bottom mold 1 and the top mold 2 away from the hinge, thus completing the connection between the bottom mold 1 and the top mold 2. Process hole 1 13 and process hole 3 15 are opened on the outside of the bottom mold 1, and process hole 2 14 is opened on the outside of the top mold 2. By opening three process holes on the outside of the bottom mold 1 and the top mold 2, it is beneficial for the outer shell and the inner sub-shell to be connected during the shell mold operation of the mold package. There are three support points to ensure that the inner sub-shell does not change during high-temperature roasting of the shell mold, thereby ensuring that the casting wall thickness variation is small and the size is accurate. A positioning part 6 is fixedly connected to the outside of the bottom mold 1. The positioning part 6 can be used for connecting multiple molds for one-time casting, and can also be used to ensure the stability of the mold when placed;
[0036] Referring to Figure 6, a cooling component is provided in the middle of the bottom mold 1. The cooling component is used to quickly cool down the bottom mold 1. The cooling component includes a cavity 19 which is opened on the inner wall of the bottom mold 1. A water injection port 17 and a water outlet 18 are fixedly connected to the outside of the bottom mold 1. Both the water injection port 17 and the water outlet 18 are communicated with the cavity 19. Cooled water is injected from the water injection port 17, and then after flowing through the inside of the cavity 19, it will be discharged from the water outlet 18. In this way, the high temperature generated during the casting of the bottom mold 1 can be adsorbed and discharged, thereby improving the cooling speed of the bottom mold 1 and greatly improving the mold casting efficiency.
[0037] Refer to Figure 2 , Figure 4 and Figure 5 , a side cover 3 is rotatably connected to the outside of the top mold 2. The size of the side cover 3 is adapted to the opening size of the casting port 4. The casting port 4 can be blocked by the side cover 3 to ensure the integrity of the bottom mold 1 and the top mold 2. Reinforcing hoops 16 are fixedly connected to the outer surfaces of the bottom mold 1 and the top mold 2 to enhance the strength of the edges of the bottom mold 1 and the top mold 2 through the reinforcing hoops 16. A dial 11 is fixedly connected to the top of the threaded rod 8. After adding the dial 11, it is more convenient to turn the threaded rod 8. A guiding groove 12 is opened at the top of the holder 9. The outer edge of the guiding groove 12 is inclined. After adding the guiding groove 12, the position of the nut 10 can be restricted during locking, and at the same time, when demolding is required, it is convenient for the nut 10 to disengage from the holder 9. A reinforcing mesh 20 is fixedly connected to the middle of the inner wall of the top mold 2. The middle thickness of the top mold 2 is 0.45 mm. The structural strength of the top mold 2 is enhanced through the reinforcing mesh 20, so that the central thickness of the top mold 2 can be reduced to 0.45 mm. A sealing ring 21 is fixedly connected to the bottom edge of the top mold 2. The sealing ring 21 is in contact with the bottom mold 1 to increase the sealing performance between the bottom mold 1 and the top mold 2 through the sealing ring 21.
[0038] Working principle: The top mold 2 is clamped with the bottom mold 1 along the rotating shaft. Then the threaded rod 8 is rotated to the middle of the holder 9, and then the nut 10 is rotated on the upper part of the holder 9 so that the nut 10 rotates on the top of the threaded rod 8 and approaches the holder 9 to complete the clamping of the bottom mold 1 and the top mold 2. Then the side cover 3 is opened to expose the casting port 4. Wax is cast into the chamber formed by the bottom mold 1 and the top mold 2 through the casting port 4, and then a golf ball head is cast by the lost wax method. After the metal casting is completed, cooled water can be injected from the water injection port 17, and then the cooled water will enter the inside of the cavity 19 and then be discharged from the water outlet 18. In this way, the internal temperature of the bottom mold 1 can be taken out, thereby improving the cooling efficiency of the mold and greatly reducing the casting time.
[0039] Secondly, after the cooling is completed, just bend the paddle 11 outward, which can drive the threaded rod 8 and the nut 10 to slide along the surface of the guiding groove 12. At this time, the threaded rod 8 will disengage from the middle of the clamping frame 9, and the separation of the bottom mold 1 and the top mold 2 can be completed. In this way, it is convenient to take out the ball heads cast inside the bottom mold 1 and the top mold 2. The operation is simple, the demoulding is very convenient, and the problems of resource waste and cost increase caused by breaking the ceramic mold are reduced.
[0040] The usage method of this casting mold is as follows:
[0041] S1. Add three process holes at the toe and trailing edge of the wax part, which is beneficial for the outer shell and the inner sub-shell in the cavity to be connected during the shell mold operation of wrapping the mold. There are three support points to ensure that the inner cavity does not mutate under high-temperature roasting of the shell mold, so as to ensure that the casting wall thickness variation is small and the size is accurate;
[0042] S2. Then, the wax injection operation conditions: the wax tank is 78 degrees, the injection port is 56 degrees, the pressure is 50KG / CM3, and the wax injection time is 12 seconds; ensure the formation of the wax embryo;
[0043] S3. Then set the shell mold wrapping operation to six and a half layers (two zircon + 35S sand + 35S sand + 22S sand + 22S sand + sealant). Each layer of the shell mold is dried for 12H to ensure the strength of the shell mold;
[0044] S4. Before casting, the shell mold is preheated and sintered for 15 to 20 minutes (the furnace temperature reaches 900 degrees to 1000 degrees); after the shell mold is preheated and cooled, it is put into the furnace for roasting for more than 60 minutes to ensure that the shell mold is thoroughly roasted. The set value of the sintering temperature of the shell mold is 1360 degrees, and the melting temperature of the molten steel reaches 1720 degrees; during casting, a special person controls to close the furnace door in time every time a string is taken out of the furnace to ensure the stability of the shell mold temperature; when taking out of the furnace, the fork furnace and the furnace operator cooperate to complete the casting within 2 minutes and 30 seconds.
[0045] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
