During the die casting process, it is necessary to continuously expel the air from the mold and prevent the molten aluminum from overflowing. Therefore, a special exhaust device is required to work with the aluminum casting mold.

[0003] However, the exhaust system currently used in conjunction with aluminum casting mold production still has some defects in use. It cannot automatically switch on and off during use, which makes it easy for dust to enter and affect the subsequent exhaust effect.

[0004] A novel venting system for aluminum casting molds is proposed to address the aforementioned problems. Utility Model Content

[0005] The purpose of this invention is to provide an exhaust system for aluminum casting molds to solve the problem of the inability to automatically switch on and off as mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an exhaust system for an aluminum casting mold, comprising an air guide tank, a support leg fixedly connected to the bottom end of the air guide tank, an air inlet fixedly connected to the top left side of the air guide tank, an air outlet fixedly connected to the right side of the air guide tank, and a reset structure for an automatic shut-off device provided inside the air guide tank.

[0007] The reset structure includes a movable plug, which is movably connected inside the air guide can. A positioning ring is fixedly connected to the top of the air guide can. A movable groove is movably connected to the bottom of the movable plug. A limiting post is movably connected inside the movable groove. A spring is fixedly connected to the bottom of the movable plug. A connecting plate is fixedly connected to the bottom of the limiting post.

[0008] As a further technical solution of this utility model, the movable plug is movably connected to the positioning ring, and the spring is fixedly connected to the connecting disc.

[0009] As a further technical solution of this utility model, the center line of the movable groove and the center line of the movable plug are on the same vertical plane, and the center line of the limiting post and the center line of the connecting plate are on the same vertical plane.

[0010] As a further technical solution of this utility model, a hexagonal groove is provided at the bottom of the air guide tank, a threaded rod is fixedly connected to the bottom of the connecting plate, a fixing collar is fixedly connected to the bottom of the air guide tank, an adjusting nut is movably connected to the bottom of the air guide tank, and a positioning plate is fixedly connected to the top of the adjusting nut.

[0011] As a further technical solution of this utility model, the positioning plate is movably connected to the fixing collar, and the threaded rod passes through the bottom end of the air guide tank and extends into the interior of the adjusting nut for threaded connection.

[0012] As a further technical solution of this utility model, the hexagonal groove is movably connected to the connecting plate, and the center line of the threaded rod and the center line of the connecting plate are on the same vertical plane.

[0013] As a further technical solution of this utility model, a connecting pipe is fixedly connected to the left side of the air inlet, a corrugated hose is fixedly connected to the bottom end of the connecting pipe, a connecting plate is fixedly connected to the bottom end of the corrugated hose, a threaded sleeve is fixedly connected to the right side inside the connecting plate, a fixing frame is fixedly connected to the bottom left side of the air guide tank, a threaded shaft is movably connected inside the fixing frame, a knob is fixedly connected to the bottom end of the fixing frame through the threaded shaft, and a connecting nozzle is fixedly connected to the left side of the bottom of the connecting plate.

[0014] As a further technical solution of this utility model, the connecting nozzle penetrates the connecting plate and is connected to the interior of the corrugated hose, and the threaded shaft is threadedly connected to the threaded sleeve.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the exhaust system of the aluminum casting mold not only realizes automatic opening and closing and the ability to adjust the exhaust pressure, but also realizes rapid connection with the aluminum casting mold;

[0016] (1) By setting a movable plug, positioning ring, movable groove, connecting plate, spring and limiting post, when the device is connected to the exhaust channel of the aluminum casting mold, the air in the mold is introduced into the top of the air guide tank through the air inlet. When the air pressure at the top of the air guide tank reaches a certain value, it will push the movable plug down. After the movable plug falls down, the air outlet is connected to the inside of the air guide tank, so that the air is discharged from the air outlet. When the air pressure drops, the spring quickly pushes the movable plug back to make it fit against the bottom of the positioning ring to prevent the aluminum liquid from overflowing and automatically close the device, thus realizing the automatic closing of the device.

[0017] (2) By setting an adjusting nut, a positioning plate, a fixing collar, a threaded rod, a connecting plate, a spring, a limiting post and a hexagonal groove, the adjusting nut can be rotated before exhaust to drive the threaded rod to rise. When the threaded rod rises, it pushes the connecting plate to rise. The connecting plate squeezes the spring to tighten it, thereby increasing the air pressure required to push the movable plug. The limiting post at the top of the connecting plate can support the spring and prevent it from bending and affecting the support force on the movable plug. The positioning plate outside the adjusting nut fits inside the fixing collar to maintain the height of the connecting plate, thus realizing the ability to adjust the air pressure required for exhaust.

[0018] (3) By setting an air inlet, connecting pipe, corrugated hose, connecting plate, connecting nozzle, fixing frame, knob, threaded sleeve and threaded shaft, before venting, the device is placed near the venting channel of the aluminum casting mold. Rotating the knob drives the threaded shaft to rotate. The threaded shaft drives the connecting plate to descend through the threaded sleeve. The connecting plate drives the connecting nozzle to descend so that it is inserted into the venting channel of the aluminum casting mold. Then the threaded shaft can be positioned by the connecting plate to keep it connected to the inside of the mold so as to facilitate venting. This realizes that it can quickly connect with the aluminum casting mold for venting. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example: Please refer to Figure 1-4 An exhaust system for an aluminum casting mold includes an air guide tank 1, a support leg 13 fixedly connected to the bottom end of the air guide tank 1, an air inlet 6 fixedly connected to the top left side of the air guide tank 1, an air outlet 3 fixedly connected to the right side of the air guide tank 1, and a reset structure for an automatic shut-off device is provided inside the air guide tank 1.

[0026] The reset structure includes a movable plug 2, which is movably connected inside the air tank 1. A positioning ring 4 is fixedly connected to the top of the air tank 1. A movable groove 5 is movably connected to the bottom of the movable plug 2. A limit post 20 is movably connected inside the movable groove 5. A spring 19 is fixedly connected to the bottom of the movable plug 2. A connecting plate 18 is fixedly connected to the bottom of the limit post 20.

[0027] The movable plug 2 is movably connected to the positioning ring 4, and the spring 19 is fixedly connected to the connecting plate 18;

[0028] The centerline of the movable groove 5 and the centerline of the movable plug 2 are on the same vertical plane, and the centerline of the limiting post 20 and the centerline of the connecting plate 18 are on the same vertical plane.

[0029] Specifically, such as Figure 1 and Figure 3 As shown, when the device is connected to the exhaust channel of the aluminum casting mold, the air inside the mold is introduced into the top of the air guide tank 1 through the air inlet 6. When the air pressure at the top of the air guide tank 1 reaches a certain value, it will push the movable plug 2 down. After the movable plug 2 falls, the air outlet 3 is connected to the inside of the air guide tank 1, thereby venting the air out from the air outlet 3. When the air pressure decreases, the spring 19 quickly pushes the movable plug 2 back to fit against the bottom of the positioning ring 4 to prevent the aluminum liquid from overflowing and automatically shut down the device, thus realizing the automatic shutdown of the device.

[0030] The bottom of the air tank 1 is provided with a hexagonal groove 21. The bottom of the connecting plate 18 is fixedly connected with a threaded rod 17. The bottom of the air tank 1 is fixedly connected with a fixing collar 16. The bottom of the air tank 1 is movably connected with an adjusting nut 14. The top of the adjusting nut 14 is fixedly connected with a positioning plate 15.

[0031] The positioning plate 15 is movably connected to the fixing collar 16, and the threaded rod 17 passes through the bottom end of the air guide tank 1 and extends into the interior of the adjusting nut 14 and is threadedly connected to it.

[0032] The hexagonal groove 21 is movably connected to the connecting plate 18, and the center line of the threaded rod 17 and the center line of the connecting plate 18 are on the same vertical plane;

[0033] Specifically, such as Figure 1 and Figure 3 As shown, before exhaust, the adjusting nut 14 can be rotated to raise the threaded rod 17. As the threaded rod 17 rises, it pushes the connecting plate 18 upward. The connecting plate 18 compresses the spring 19 to tighten it, thereby increasing the air pressure required to push the movable plug 2. The limiting post 20 at the top of the connecting plate 18 can support the spring 19 to prevent it from bending and affecting the supporting force on the movable plug 2. The positioning plate 15 outside the adjusting nut 14 fits inside the fixing collar 16 to maintain the height of the connecting plate 18, thus realizing the ability to adjust the air pressure required for exhaust.

[0034] A connecting pipe 7 is fixedly connected to the left side of the air inlet 6. A corrugated hose 8 is fixedly connected to the bottom end of the connecting pipe 7. A connecting plate 9 is fixedly connected to the bottom end of the corrugated hose 8. A threaded sleeve 22 is fixedly connected to the right side inside the connecting plate 9. A fixed frame 11 is fixedly connected to the bottom left side of the air guide tank 1. A threaded shaft 23 is movably connected inside the fixed frame 11. A knob 12 is fixedly connected to the bottom end of the fixed frame 11 through the threaded shaft 23. A connecting nozzle 10 is fixedly connected to the left side of the bottom of the connecting plate 9.

[0035] The connecting nozzle 10 passes through the connecting plate 9 and is connected to the interior of the corrugated hose 8; the threaded shaft 23 is threadedly connected to the threaded sleeve 22.

[0036] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, before venting, the device is placed near the venting channel of the aluminum casting mold. Rotating the knob 12 drives the threaded shaft 23 to rotate. The threaded shaft 23 drives the connecting plate 9 to descend through the threaded sleeve 22. The connecting plate 9 drives the connecting nozzle 10 to descend and insert it into the venting channel of the aluminum casting mold. Then, the threaded shaft 23 can be positioned by the connecting plate 9 to keep it in communication with the inside of the mold, so as to facilitate venting. This allows for quick communication with the aluminum casting mold for venting.

[0037] Working Principle: In use, this device is placed near the venting channel of the aluminum casting mold. Rotating knob 12 rotates the threaded shaft 23, which, through the threaded sleeve 22, lowers the connecting plate 9. The connecting plate 9 then lowers the connecting nozzle 10, inserting it into the venting channel of the aluminum casting mold. The threaded shaft 23 can then be positioned by the connecting plate 9 to maintain communication with the mold interior, facilitating venting. Before venting, rotating the adjusting nut 14 raises the threaded rod 17. Simultaneously, the rising threaded rod 17 pushes the connecting plate 18 upwards, compressing the spring 19 and tightening it. This increases the air pressure required to push the movable plug 2. Furthermore, the connecting plate 18... The top limiting post 20 can support the spring 19 to prevent it from bending and affecting the supporting force on the movable plug 2. The positioning plate 15 outside the adjusting nut 14 fits inside the fixing collar 16 to maintain the height of the connecting plate 18. When the device is connected to the exhaust channel of the aluminum casting mold, the air in the mold is introduced into the top of the air guide tank 1 through the air inlet 6. When the air pressure at the top of the air guide tank 1 reaches a certain value, it will push the movable plug 2 down. After the movable plug 2 falls, the air outlet 3 connects with the inside of the air guide tank 1, thereby venting the air from the air outlet 3. When the air pressure decreases, the spring 19 quickly pushes the movable plug 2 back to fit against the bottom of the positioning ring 4 to prevent the aluminum liquid from overflowing and automatically shut down the device.
