DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-3 A fairing runner mold comprises a body 1, a lower mold 2 is fixedly installed on the top surface of the body 1, an upper mold 3 is slidably installed in the body 1, the body 1 is connected to the upper mold 3 through a driving mechanism, the driving mechanism comprises a plurality of slide columns 4 symmetrically installed on the bottom surface of the body 1, and each slide column 4 is slidably connected to the upper mold 3, two threaded rods 5 are symmetrically rotated and connected to the top surface of the body 1, and each threaded rod 5 is threadedly connected to the upper mold 3, a plurality of threaded sleeves 7 are symmetrically installed on the outer side of the upper mold 3, and each threaded sleeve 7 is threadedly connected to the threaded rod 5 corresponding to the position, a plurality of slide seats 6 are symmetrically installed on the outer side of the upper mold 3, and each slide seat 6 is slidably connected to the slide column 4 corresponding to the position, the two threaded rods 5 are connected by a synchronization mechanism, and then the upper mold 3 can slide up and down by synchronously rotating the two threaded rods 5 in different directions, and the two threaded rods 5 and the slide column 4 can ensure that the upper mold 3 is stable during the sliding process to prevent it from tilting;

[0022] The synchronization mechanism includes two synchronization wheels 13, and the two synchronization wheels 13 are respectively installed at the top of the threaded rod 5 at corresponding positions. The two synchronization wheels 13 are jointly sleeved with a synchronization belt 14, so that the two threaded rods 5 rotate synchronously;

[0023] A fixing seat 16 is fixedly installed on the top of the machine body 1, and a motor 15 is fixedly installed on the top surface of the fixing seat 16. The output shaft of the motor 15 passes through the fixing seat 16 and is connected to one of the threaded rods 5. By starting the motor 15, one of the threaded rods 5 is driven to rotate, thereby driving the upper mold 3 to slide.

[0024] A liquid storage tank 19 is fixedly installed on the top surface of the machine body 1, and a liquid inlet pipe is connected to the liquid storage tank 19. A plurality of heating elements 17 are symmetrically installed on the inner wall of the liquid storage tank 19, so as to maintain a constant temperature of the metal liquid inside the liquid storage tank 19. The liquid storage tank 19 is respectively connected with a second connecting pipe and an exhaust pipe 20, and the second connecting pipe is connected with the inside of the upper mold 3 through a diverter seat 8. A plurality of branch runners 18 are symmetrically opened in the upper mold 3, and each branch runner 18 is connected with the diverter seat 8, so that the metal liquid flows into the inside of multiple mold cavities through the plurality of branch runners 18 at the same time, thereby making the casting speed faster;

[0025] The outside of the lower mold 2 is connected to a water pump 11 through a first connecting pipe 10, and the water pump 11 is connected to a liquid storage tank 19 through a reflux pipe 12. Check valves 9 are installed on the second connecting pipe and the first connecting pipe 10. The metal liquid inside the liquid storage tank 19 enters the cavity formed by the upper mold 3 and the lower mold 2 through the second connecting pipe, thereby squeezing out the air inside. The air enters the liquid storage tank 19 through the first connecting pipe 10 and the water pump 11, and then enters the mold cavity, forming a closure between the liquid storage tank 19. The liquid storage tank 19 is connected to an exhaust pipe 20, and then the gas floats up and passes through the liquid storage tank 19, so that only metal liquid exists in the cavity, thereby achieving the effect of exhausting the gas, avoiding bubbles in the generated fairing and affecting the performance of the fairing.

[0026] When the utility model is used, the motor 15 is started to drive the two threaded rods 5 to rotate synchronously, and then the upper mold 3 is driven to move downward, so that the upper mold 3 and the lower mold 2 are closely fitted to form a seal, and then the water pump 11 can be started to extract the gas in the mold cavity through the first connecting pipe 10, and the air is discharged to the liquid storage tank 19 through the return pipe 12, and then the gas is discharged to the external device through the liquid storage tank 19;

[0027] At the same time, when the air inside the mold cavity is exhausted, the metal liquid slowly circulates back and forth between the mold cavity and the return pipe 12. It is worth noting that the return pipe 12 is connected to the interior of the upper mold 3 through the check valve 9 and the diverter seat 8, and there are multiple branch runners 18 symmetrically in the upper mold 3, and then the mold cavity is filled through multiple liquid storage tanks 19 until the metal liquid fills the entire mold cavity, so that the casting is more uniform, and then the first connecting pipe 10 and the second connecting pipe are closed successively through the check valve 9 on the first connecting pipe 10 and the second connecting pipe. After the metal liquid in the mold cavity cools down, the motor 15 can be started again to separate the upper mold 3 and the lower mold 2, and then the fairing can be removed.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
