[0027] Embodiment:

[0028] Please refer to Figure 1-2 , a circular copper rod graphite mold, including a lower die 1 and an upper die 2. Both ends of the lower die 1 and the upper die 2 close to each other are provided with mold cavities 3, and a pair of mold cavities 3 are matched. One end of the lower die 1 is installed with an electric push rod 4, and an adjusting block 5 matching it is arranged in the inner cavity of the lower die 1. The output end of the electric push rod 4 extends into the inner cavity of the mold cavity 3 and is fixedly connected with the adjusting block 5. An injection hole 10 is opened at the top of the upper die 2 on the side far from the electric push rod 4, and the injection hole 10 is communicated with the mold cavity 3.

[0029] When making circular copper rods, a cylindrical cavity matching the copper rod will also be correspondingly formed in the graphite mold. When making a large number of copper rods, there are usually different requirements for the length of the copper rods. When making copper rods of different lengths, molds with different cavity sizes need to be replaced, which reduces production efficiency and increases manufacturing costs at the same time.

[0030] In this solution, the lower mold 1 and the upper mold 2 are both made of graphite material. Among them, the upper mold 2 is connected to the hydraulic device. The user controls the lifting of the upper mold 2 through the hydraulic device to combine the upper mold 2 with the lower mold 1. The cavities 3 in the lower mold 1 and the upper mold 2 will be combined into a cylindrical cavity. Then, the user can inject the liquid melt for making the copper rod into the cavity 3 through the injection hole 10. The melt cools and solidifies in the cavity 3 to form the finished copper rod. The user can push the adjusting block 5 to move in the cavity 3 by controlling the electric push rod 4. The adjusting block 5 matches the inner cavity of the cavity 3, and the outer end of the adjusting block 5 is closely attached to the inner wall of the cavity 3. By adjusting the position of the adjusting block 5 in the cavity 3, the size of the space in the cavity 3 can be changed. The melt injected into the cavity 3 through the injection hole 10 cannot flow to the other side of the adjusting block 5 after contacting the adjusting block 5. With such a setting, the length of the finished copper rod can be changed, and the purpose of making copper rods of different lengths with a set of molds can be achieved.

[0031] Please refer to Figure 1 and 4 As shown in, a cooling box 6 is provided on one side of the lower mold 1. A liquid inlet pipe is installed at one end of the cooling box 6. The liquid inlet pipe penetrates the side wall of the lower mold 1 and is communicated with the cavity 3. A plurality of heat conducting rods 9 are inlaid and installed on the adjusting block 5. The heat conducting rods 9 and the end of the adjusting block 5 away from the electric push rod 4 are in the same plane.

[0032] There may still be heat inside the copper rod after melting and casting. Therefore, cooling is required to ensure that the copper rod is completely solidified and maintains its shape. In the existing solutions, the copper rod is mostly taken out of the mold and then cooled. In this solution, the cooling box 6 is filled with coolant and a water pump is installed. The coolant can be injected into the interior of the cavity 3 through the liquid inlet pipe by the water pump, so that the coolant fills the inner cavity of the cavity 3 on one side of the adjusting block 5. A plurality of heat conducting rods 9 are all in full contact with the coolant. The material of the heat conducting rods 9 can be set as copper, which has excellent heat conducting performance. The other end of the heat conducting rods 9 is in contact with the finished copper rod in the cavity 3, and the heat of the copper rod can be conducted into the coolant, so that the coolant can quickly absorb the heat of the copper rod and cool the copper rod. By directly injecting the coolant into the cavity 3 for cooling the copper rod, the cooling speed of the copper rod can be effectively increased, and the shape and size of the copper rod can be better maintained, avoiding production defects caused by deformation.

[0033] Please refer to Figure 2 and4 , one end of the upper mold 2 is fixedly connected with a drain pipe 7. The drain pipe 7 penetrates through the side wall of the upper mold 2 and is communicated with the mold cavity 3. Cooling channels 8 are opened at both ends of the lower mold 1 and the upper mold 2 close to each other. A pair of cooling channels 8 are matched with each other. The cooling channels 8 are arranged around the mold cavity 3. A pair of cooling channels 8 are respectively communicated with a pair of mold cavities 3.

[0034] The coolant injected into the mold cavity 3 can enter the cooling channel 8, so that the coolant can flow around the copper rod, which can more effectively absorb the heat dissipated by the copper rod in all directions. At the same time, it can also play the role of cooling the lower mold 1 and the upper mold 2. Cooling the mold in time during the process of making the copper rod can reduce the thermal stress inside the mold, which helps to reduce the deformation and cracks of the mold. The drain pipe 7 is installed on the upper mold 2, which can ensure that when the coolant fills the inner cavities of the mold cavity 3 and the cooling channel 8, it is then discharged through the drain pipe 7, so as to keep the coolant flowing and improve the cooling speed.

[0035] Working principle:

[0036] During use, the user controls the lifting of the upper mold 2 through a hydraulic device to merge the upper mold 2 with the lower mold 1. The mold cavities 3 in the lower mold 1 and the upper mold 2 will merge into a cylindrical mold cavity. Then, the user injects the liquid melt for making the copper rod into the mold cavity 3 through the injection hole 10. The melt cools and solidifies in the mold cavity 3 to form the finished copper rod. The user can push the adjusting block 5 to move in the mold cavity 3 by controlling the electric push rod 4. By adjusting the position of the adjusting block 5 in the mold cavity 3, the size of the space in the mold cavity 3 can be changed. The melt injected into the mold cavity 3 through the injection hole 10 cannot flow to the other side of the adjusting block 5 after contacting the adjusting block 5. With such a setting, the length of the finished copper rod can be changed, and the purpose of making copper rods of different lengths with a set of molds can be achieved. After the copper rod is formed, the user starts the water pump in the cooling box 6, and injects the coolant in the cooling box 6 into the inside of the mold cavity 3 through the liquid inlet pipe by the water pump, so that the coolant fills the inner cavity of the mold cavity 3 on one side of the adjusting block 5. A plurality of heat conducting rods 9 are all in full contact with the coolant, and the other end of the heat conducting rod 9 is in contact with the finished copper rod in the mold cavity 3. The heat conducting rod 9 conducts the heat of the copper rod to the coolant, so that the coolant can quickly absorb the heat of the copper rod to cool the copper rod. At the same time, the coolant injected into the mold cavity 3 can enter the cooling channel 8, so that the coolant can flow around the copper rod, which can more effectively absorb the heat dissipated by the copper rod in all directions. At the same time, it can also play the role of cooling the lower mold 1 and the upper mold 2. When the coolant fills the inner cavities of the mold cavity 3 and the cooling channel 8, it is then discharged through the drain pipe 7 to keep the coolant flowing for use.

[0037] The above are only the preferred specific embodiments of the present utility model; however, the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
