Description

Technical Field

[0001] This utility model belongs to the technical field of molds for oxygen-free copper rods, and in particular relates to a graphite mold for the production of oxygen-free copper rods. Background Technology

[0002] Oxygen-free copper rods are a type of high-purity copper material widely used in the electronics, electrical, and communications fields. During the upward forming process, the copper rod initially exists in a liquid state, which is then condensed into a solid state via a condenser in a crystallizer. This liquid-to-solid transition occurs within a graphite mold. After solidification, the copper rod is cooled by a core rod before being produced. However, the cooling system design of traditional graphite molds in existing technologies is flawed, leading to uneven cooling of the molten copper. This affects the internal structure and surface quality of the copper rod, and the molten copper tends to adhere to the inner wall of the mold during cooling, resulting in a rough surface and even defects. Utility Model Content

[0003] Based on the above background, the purpose of this utility model is to provide a graphite mold for the production of oxygen-free copper rods.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A graphite mold for producing oxygen-free copper rods includes a base and a mold body; a condenser tube is fixedly mounted on the base, and the mold body is rotatably disposed inside the condenser tube and coaxially arranged with the condenser tube.

[0006] It also includes a liquid storage tank, one end of which is cylindrical and the other end is funnel-shaped. One end of the mold body is rotatably located inside the liquid storage tank and is situated at the funnel-shaped end of the liquid storage tank.

[0007] The liquid storage tank is equipped with an injection pipe, which is located on the side of one cylindrical end of the liquid storage tank.

[0008] The base is equipped with a condensation box and a recovery box. The condensation box is connected to the condensation pipe through a liquid inlet pipe, and the recovery box is connected to the condensation pipe through a liquid outlet pipe.

[0009] The liquid inlet pipe is located at the end of the condenser pipe away from the liquid storage tank, and the liquid outlet pipe is located at the end of the condenser pipe close to the liquid storage tank.

[0010] Through the above technical solution, molten copper is injected into the storage tank through the injection pipe, and then flows into the mold body from the funnel-shaped end of the storage tank. The condensate in the condensation tank enters the condenser tube through the inlet pipe to cool the molten copper inside the mold body. The inlet pipe is located at the end of the condenser tube furthest from the storage tank, ensuring that the condensate flows gradually from the far end to the near end, thereby achieving gradual cooling and condensation of the molten copper and improving the condensation effect. Furthermore, during the rotation of the mold body, the relative movement between the molten copper and the inner wall of the mold reduces the adhesion between the molten copper and the mold, further improving the surface quality and internal uniformity of the final copper rod.

[0011] Furthermore, the base is symmetrically provided with brackets, the top of which is arc-shaped, and the condenser tube is fixedly mounted on the brackets, which better supports the condenser tube.

[0012] Furthermore, a circulation pipe is provided between the condensation tank and the recovery tank, which can cool down the condensate in the recovery tank and then transport it back to the condensation tank.

[0013] Furthermore, a mounting block is fixedly provided on the base, and a drive gear is rotatably mounted on each of the two mounting blocks. A rotating shaft connects the two drive gears.

[0014] Driven gears are provided on the outer sides of both ends of the mold body, and the driven gears are meshed with the corresponding driving gears;

[0015] One of the mounting blocks is equipped with a motor, which is connected to a corresponding drive gear.

[0016] Through the above technical solution, the motor drives the driving gear to rotate, and the driven gear meshing with the driving gear rotates, thereby driving the mold body to rotate. Furthermore, driven gears are set at both ends of the mold body to improve the stability of the mold body rotation.

[0017] Furthermore, an annular groove is provided on the inner wall of the liquid storage tank, and a rotating ring is provided on the side of the mold body. The rotating ring is rotatably disposed in the annular groove, and the outer side of the mold body abuts against the inner wall of the liquid storage tank.

[0018] The above technical solutions can improve the stability of the mold body rotation and the sealing of one end of the mold body rotating in the liquid storage tank.

[0019] Furthermore, the inner wall of the condenser tube is provided with a threaded pipe, and the two ends of the threaded pipe are respectively connected to the inlet pipe and the outlet pipe.

[0020] The above technical solution better ensures the condensation effect of the copper liquid inside the mold body.

[0021] Furthermore, there are two threaded pipes, the thread directions of the two threaded pipes are opposite, and the two threaded pipes are not connected in the middle;

[0022] The two ends of the two threaded pipes are connected to the inlet pipe and the outlet pipe respectively via tee pipes.

[0023] The above technical solution, which involves setting up two threaded pipes, can improve the uniformity of condensation.

[0024] This utility model has the following beneficial effects:

[0025] Molten copper is injected into the storage tank through the injection pipe, and then flows into the mold body from the funnel-shaped end of the storage tank. Condensate in the condensation tank enters the condenser tube through the inlet pipe, cooling the molten copper inside the mold body. The inlet pipe is located at the end of the condenser tube furthest from the storage tank, ensuring that the condensate flows gradually from the far end to the near end, thus achieving gradual cooling and condensation of the molten copper and improving the condensation effect. Furthermore, during the rotation of the mold body, the relative movement between the molten copper and the inner wall of the mold reduces adhesion between the molten copper and the mold, further improving the surface quality and internal uniformity of the final copper rod.

[0040] like Figure 1-4As shown, a graphite mold for producing oxygen-free copper rods includes a base 1 and a mold body 2. A condenser tube 3 is fixedly mounted on the base 1. A support 11 is symmetrically mounted on the base 1, with an arc-shaped top. The condenser tube 3 is fixedly mounted on the support 11, and the arc shape of the support 11 fits against the side of the condenser tube 3 for better support. The mold body 2 is rotatably disposed inside the condenser tube 3 and coaxially arranged with it. The mold body 2 also includes a liquid storage tank 4, one end of which is cylindrical and the other end is funnel-shaped. One end of the mold body 2 is rotatably disposed inside the liquid storage tank 4, located at the funnel-shaped end of the liquid storage tank 4. An injection pipe 4 is provided on the liquid storage tank 4. 1. The injection pipe 41 is located on the side of one cylindrical end of the storage tank 4. The other end of the injection pipe 41 is connected to the copper smelting equipment to transport the copper molten metal into the mold body 2. The base 1 is equipped with a condensation tank 5 and a recovery tank 6. The condensation tank 5 is connected to the condensation pipe 3 through the inlet pipe 31, and the recovery tank 6 is connected to the condensation pipe 3 through the outlet pipe 32. The inlet pipe 31 is located at the end of the condensation pipe 3 away from the storage tank 4, and the outlet pipe 32 is located at the end of the condensation pipe 3 close to the storage tank 4. A circulation pipe 51 is provided between the condensation tank 5 and the recovery tank 6, which can cool the condensate in the recovery tank 6 and return it to the condensation tank 5 to improve the utilization rate of the condensate.

[0041] During use, molten copper is injected into the storage tank 4 through the injection pipe 41, and then flows into the mold body 2 from the funnel-shaped end of the storage tank 4. The condensed liquid in the condensation tank 5 enters the condenser pipe 3 through the inlet pipe 31 to cool the molten copper in the mold body 2. During the cooling process, the mold body 2 is driven to rotate relative to the condenser pipe 3. The relative movement between the molten copper and the inner wall of the mold reduces the adhesion between the molten copper and the mold, further improving the surface quality and internal uniformity of the final copper rod.

[0042] A mounting block 12 is fixedly mounted on the base 1. Two mounting blocks 12 are rotatably mounted with drive gears 13. A rotating shaft 15 connects the two drive gears 13. Driven gears 14 are provided on the outer sides of both ends of the mold body 2. The driven gears 14 mesh with the corresponding drive gears 13. A motor 16 is mounted on one of the mounting blocks 12. The motor 16 is connected to the corresponding drive gear 13. An annular groove 42 is opened on the inner wall of the liquid storage tank 4. A rotating ring 21 is provided on the side of the mold body 2. The rotating ring 21 is rotatably mounted in the annular groove 42. The outer side of the mold body 2 abuts against the inner wall of the liquid storage tank 4. The motor 16 drives the drive gear 13 connected to it to rotate. The rotating shaft 15 drives the other drive gear 13 to rotate. The driven gear 14 meshing with the drive gear 13 rotates, thereby driving the mold body 2 to rotate. Driven gears 14 are provided at both ends of the mold body 2 to improve the stability of the rotation of the mold body 2.

[0043] The inner wall of the condenser tube 3 is provided with a threaded pipe 33. The two ends of the threaded pipe 33 are connected to the liquid inlet pipe 31 and the liquid outlet pipe 32 respectively. There are two threaded pipes 33, and the threads of the two threaded pipes 33 are opposite in direction and are not connected in the middle. The two ends of the two threaded pipes 33 are connected to the liquid inlet pipe 31 and the liquid outlet pipe 32 respectively through a T-junction. The setting of the two non-interfering threaded pipes 33 can ensure that when the condensate flows from the far end of the mold body 2 to the near end of the liquid storage tank 4, the condensate will not overlap, thus ensuring the condensation effect.

[0044] The working principle of this utility model is as follows: molten copper is injected into the storage tank 4 through the injection pipe 41, and then flows into the mold body 2 from the funnel-shaped end of the storage tank 4. At the same time, the condensed liquid in the condensation tank 5 enters the two threaded pipes 33 of the condenser pipe 3 through the inlet pipe 31 to cool the molten copper in the mold body 2. The motor 16 drives the connected drive gear 13 to rotate, and drives another drive gear 13 to rotate through the rotating shaft 15. The driven gear 14 meshing with the drive gear 13 rotates, thereby driving the mold body 2 to rotate. The relative movement between the molten copper and the inner wall of the mold reduces the adhesion between the molten copper and the mold, further improving the surface quality and internal uniformity of the final copper rod.

[0045] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
