[0029] The number of the lower casting mold fixing groove 38 and the lower casting mold 7 are both 2, and the number of the heat-conducting plate fixing groove 39, the heat-conducting plate 3 and the fan 6 are all 4.

[0030] The number of the heat dissipation plate fixing groove 35, the upper casting mold fixing groove 36, the heat dissipation plate 14 and the upper casting mold 13 are all two, and the heat dissipation plate 14 is a bottomless structure fixed on the corresponding upper casting mold 13.

[0031] The casting liquid inlet device consists of two sets with the same structure, including a first casting liquid tank 21 and a second casting liquid tank 29 fixed on the casting main body box 2. The bottom of the first casting liquid tank 21 is provided with a first liquid guide plate 20. A first casting hose 22 is fixed at the first liquid outlet at the bottom of the first casting liquid tank 21. The other end of the first casting hose 22 extends through the casting pipe through hole 40 to the inside of the upper casting mold 13. The bottom of the second casting liquid tank 29 is provided with a second liquid guide plate 30. A second casting hose 28 is fixed at the second liquid outlet at the bottom of the second casting liquid tank 29. The other end of the second casting hose 28 extends through another casting pipe through hole 40 to the inside of another upper casting mold 13.

[0032] The cooling water circulation device includes an inlet water pipe 17 and an outlet water pipe 16 extending into the heat dissipation plate 14. The inlet water pipe 17 passes through a water pipe perforation 41 and connects to an inlet water connection pipe 18.

[0034] The bottom end of the lower mold base 10 is fixed with a universal wheel support rod 9, and the universal wheel support rod 9 is connected to the universal wheel 8.

[0035] When using the casting device for manufacturing aluminum cylinders for motorcycle shock absorbers, the hydraulic cylinder 31 is first activated. The hydraulic cylinder 31 drives the fixed block 15 to move downward, causing the upper mold seat 12 to move downward. During the downward movement of the upper mold seat 12, the limiting plate 11 will insert into the limiting slot 37. When the upper mold seat 12 and the lower mold seat 10 are completely in contact, the upper casting mold 13 and the lower casting mold 7 will also be completely in contact. Then, the same amount of molten aluminum is poured into the first casting liquid tank 21 and the second casting liquid tank 29. The molten aluminum in the first casting liquid tank 21 can flow from the first casting hose 22 into the upper casting mold 13 and the lower casting mold 7 connected thereto. The molten aluminum in the second casting liquid tank 29 can flow from the second casting hose 28 into the upper casting mold 13 and the lower casting mold 7 connected thereto, thus realizing the simultaneous casting of two aluminum cylinders.

[0036] When the aluminum cylinder needs to be cooled after casting, the water pump 24 is started. The water pump 24 causes the cooling water in the cooling water tank 26 to flow out from the outlet pipe 25, and then flow into the two heat dissipation plates 14 through the inlet expansion pipe 19, the inlet connecting pipe 18, and the inlet water pipe 17 in sequence, cooling the two upper casting molds 13. The cooling water that has absorbed heat will flow back into the cooling water tank 26 through the outlet water pipe 16, the return water connecting pipe 33, the return water expansion pipe 32, and the return water pipe 27 in sequence for cooling and temperature reduction, realizing the recycling of cooling water and saving water resources.

[0037] After starting the water pump 24, start the fan 6. The fan 6 can blow air onto the heat conduction plate 3, which can accelerate the heat conduction speed of the heat conduction plate 3, which is conducive to accelerating the heat conduction of the heat conduction plate 3 to the lower casting mold 7, and accelerating the heat dissipation of the lower casting mold 7.

[0038] After the cast aluminum cylinder cools down, start the hydraulic cylinder 31. The hydraulic cylinder 31 drives the upper mold seat 12 to move upward, so that the upper mold seat 12 and the upper casting mold 13 are raised. Then, take out one aluminum cylinder first, and then start the motor 4. The motor 4 drives the rotating shaft 5 to rotate so that the lower mold seat 10 can rotate 180°. Then the second aluminum cylinder can be taken out.

[0039] In this utility model, a lower mold base 10 and an upper mold base 12 are provided. Two lower casting molds 7 of the same size are provided in the lower mold base 10, and two upper casting molds 13 of the same size are provided in the upper mold base 12. The two upper casting molds 13 are respectively connected to separate casting liquid inlet devices, which can cast two aluminum cylinders at the same time, thereby improving the production efficiency of aluminum cylinders.

[0040] In this invention, a heat dissipation plate 14 is fixed on the upper casting mold 13, and the heat dissipation plate 14 is connected to a cooling water circulation device, which can provide water cooling for the upper casting mold 13; a heat conduction plate 3 is attached to the lower casting mold 7, which can conduct the heat on the lower casting mold 7 to the outside, and a fan 6 is provided below the heat conduction plate 3, which can blow air onto the heat conduction plate 3, which can accelerate the air flow at the heat conduction plate 3 and accelerate the heat dissipation of the heat conduction plate 3; by using water cooling and air cooling, the cooling time of the aluminum cylinder is increased, which further improves the production efficiency of the enterprise.

[0041] In this utility model, a motor 4 and a rotating shaft 5 are provided, which can drive the lower mold base 10 to rotate 180°, which facilitates the unloading of the two aluminum cylinders after casting and cooling. The fixed 180° rotation angle enables the lower casting mold 7 and the upper casting mold 13 to be quickly recast, which is beneficial to the stability of production efficiency.

[0042] In this utility model, a limiting insert plate 11 is provided in the middle of the lower mold base 10, and a limiting slot 37 is provided in the middle of the upper mold base 12. During the mold closing process of the lower mold base 10 and the upper mold base 12, the limiting insert plate 11 can be inserted into the limiting slot 37, which helps to ensure the accuracy of the mold closing position of the lower mold base 10 and the upper mold base 12.

[0043] In this invention, a first liquid guide plate 20 is provided in the first casting liquid tank 21, and a second liquid guide plate 30 is provided in the second casting liquid tank 29, which facilitates the complete outflow of aluminum liquid in the first casting liquid tank 21 and the second casting liquid tank 29.
