Description

Technical Field

[0001] This invention relates to the field of aluminum alloy casting cooling technology, specifically a cooling device for aluminum alloy casting. Background Technology

[0002] Aluminum alloy casting is a process that uses melting and casting methods to inject molten aluminum into a mold cavity to form a shape. Aluminum alloy casting includes two basic methods: die casting and gravity casting. Die casting is further divided into low-pressure die casting and high-pressure die casting; while gravity casting can be divided into sand casting and metal mold or resin mold casting. After casting, aluminum alloys need to be cooled, and there are two cooling methods: water cooling and air cooling.

[0003] However, currently, round aluminum alloy wheels need to be cooled after casting. According to the production process, air cooling is generally used for cooling. When cooling aluminum alloy wheels with air cooling, the wheels are placed directly at the air outlet of the fan using a hanger. The cooling speed is slow and the cooling time is long, which is a waste of time. Moreover, after cooling, the aluminum alloy wheels are usually unloaded manually, which increases the labor intensity of the workers. Summary of the Invention

[0004] To address the problems in the prior art, the present invention provides a cooling device for aluminum alloy casting.

[0005] The technical solution adopted by this invention to solve its technical problem is: a cooling device for aluminum alloy casting, comprising:

[0006] Control panel;

[0007] A lifting mechanism is installed on the operating table. The lifting mechanism includes a sliding shell, a sliding shell fixed to the bottom of the operating table, an outer shell fixed to the bottom of the sliding shell, a crank handle rotatably connected to the outer shell, a worm gear fixedly connected to the crank handle, a worm wheel rotatably connected to the inside of the outer shell and meshing with the worm gear, a toothed plate extending into the interior of the sliding shell slidably connected to the outer shell, the toothed plate meshing with the worm wheel, and an ice storage mechanism slidably connected to the inside of the sliding shell.

[0008] Specifically, the lifting mechanism also includes a top plate, and the top of the toothed plate is fixedly connected to the top of the toothed plate.

[0009] Specifically, an ice storage mechanism for holding ice blocks is slidably connected to the operating table. The ice storage mechanism includes a water receiving tank. The water receiving tank extends into the sliding shell and is slidably connected to the operating table. Multiple support rods are fixed inside the water receiving tank. A material box that abuts against the support rods is placed inside the water receiving tank. The water receiving tank abuts against the top plate.

[0010] Specifically, the ice storage mechanism also includes a water pipe, and the side wall of the water receiving tank is connected to the water pipe.

[0011] Specifically, the lifting mechanism also includes a side groove, the side wall of the sliding shell is provided with a side groove, and the water pipe is slidably connected to the side groove.

[0012] Specifically, the operating table is equipped with an air-cooling mechanism for cooling aluminum alloy workpieces. The air-cooling mechanism includes a slide groove. The operating table has a slide groove, and a slide block is slidably connected to the slide groove. A lead screw that rotates with the operating table is threaded onto the slide block, and a fan is installed on the slide block.

[0013] Specifically, a placement mechanism for placing round aluminum alloy workpieces is rotatably connected to the operating table. The placement mechanism includes a rotating shaft, which is rotatably connected to the opening on the surface of the operating table. An outer frame is rotatably connected to the rotating shaft, and a placement plate is fixedly connected inside the outer frame. A slot is provided on the side wall of the outer frame, and a locking post is slidably connected to the operating table. A spring is clamped between the locking post and the operating table, and the locking post is engaged in the slot.

[0014] Specifically, the surface of the placement plate is provided with holes at equal intervals, and the surface of the placement plate is provided with grooves.

[0015] Specifically, a drive mechanism is installed between the placement mechanism and the operating table; the drive mechanism includes two limiting plates, two limiting plates are fixedly connected to the operating table, a pull frame is slidably connected to the two limiting plates, a roller is rotatably connected to the pull frame, pressure grooves are inclinedly opened on both sides of the outer frame, the roller is rotatably connected to the pressure groove, and a pedal is fixed on the pull frame.

[0016] The beneficial effects of this invention are:

[0017] (1) The cooling device for aluminum alloy casting described in this invention has an air-cooling mechanism on the operating table. After the round aluminum alloy wheel hub workpiece is placed on the placement mechanism, ice blocks can be added to the ice storage mechanism on the lifting mechanism. As the air-cooling mechanism generates wind energy, the cold air on the ice blocks is carried away and blown onto the aluminum alloy wheel hub on the placement mechanism, thereby achieving rapid cooling of the aluminum alloy wheel hub and saving time. That is, after the aluminum alloy wheel hub is placed, ice blocks are added to the inside of the material box. The ice blocks can lower the temperature of the surrounding air. The fan is then started, which blows the cold air toward the wheel hub, improving the cooling efficiency. The screw can be rotated to make the slide block slide on the slide groove. The closer the fan is to the material box, the faster the cold air flows, which can also improve the air-cooling efficiency. As the air flows and the ice blocks absorb heat and melt, the ice water flows from the material box to the inside of the water receiving tank. The switch on the water pipe is then opened to process the ice water and prevent the cold water from flowing to the bottom of the operating table and causing pollution.

[0018] (2) The cooling device for aluminum alloy casting described in this invention has a lifting mechanism on the operating table, and the lifting mechanism is slidably connected to the ice storage mechanism. When air cooling the aluminum alloy hub, the lifting mechanism can be rotated to allow cold air to blow over the aluminum alloy hub layer by layer, achieving uniform heat dissipation and facilitating the casting of the aluminum alloy hub. That is, when cooling the aluminum alloy hub with ice blocks inside the material box, the highest point of the material box can be aligned with the highest point of the hub first. Then, the crank can be turned at regular intervals to drive the worm gear to rotate. As the worm gear rotates, it drives the worm wheel to rotate. Since the worm wheel meshes with the toothed plate, as the worm wheel rotates, the toothed plate can gradually slide down, further driving the top plate to slide down, thereby lowering the water tank and finally cooling the aluminum alloy hub layer by layer. Turning the crank in the opposite direction raises the material box, which can also cool the aluminum alloy hub layer by layer.

[0019] (3) The cooling device for aluminum alloy casting described in this invention has a driving mechanism on the placement mechanism. After the aluminum alloy wheel hub is cooled, the locking pin is pulled and the driving mechanism is pressed to tilt the placement plate, so that the aluminum alloy wheel hub rolls out. A conveying device is set at the bottom of the placement plate to realize the rapid unloading of the aluminum alloy wheel hub and reduce the labor intensity of the workers; that is, after the aluminum alloy wheel hub is cast, it is placed on the placement plate by a lifting device. The placement plate has a groove to facilitate the placement of the wheel hub. At this time, the locking pin and the groove are in a position In the engaged state, the aluminum alloy wheel hub will not roll. After the aluminum alloy wheel hub has cooled down, pull the locking pin away from the operating table. The spring will contract, further separating the locking pin from the locking slot. At the same time, stepping on the pedal will cause the pull frame to slide down the limit plate. Furthermore, due to the inclined pressure groove on the side wall of the outer frame, the roller will roll inside the pressure groove when the pull frame slides down, thereby enabling the placement plate to rotate around the pivot point. This achieves rapid unloading and saves effort. By installing a conveyor at the bottom of the placement plate, the cooled aluminum alloy wheel hub can be transferred. Attached Figure Description

[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0031] like Figures 1-8 As shown, the cooling device for aluminum alloy casting of the present invention includes an operating table 1, an air-cooling mechanism 2 for cooling aluminum alloy workpieces is installed on the operating table 1, a lifting mechanism 4 is installed on the operating table 1, an ice storage mechanism 3 for holding ice blocks is slidably connected to the operating table 1, the ice storage mechanism 3 is slidably connected to the inside of the lifting mechanism 4, a placement mechanism 5 for placing round aluminum alloy workpieces is rotatably connected to the operating table 1, and a driving mechanism 6 is installed between the placement mechanism 5 and the operating table 1.

[0032] The lifting mechanism 4 includes a sliding shell 403, which is fixed to the bottom of the operating table 1. A housing 401 is fixed to the bottom of the sliding shell 403. A crank handle 402 is rotatably connected to the housing 401, and a worm gear 407 is fixedly connected to the crank handle 402. A worm wheel 408, meshing with the worm gear 407, is rotatably connected inside the housing 401. A toothed plate 405 extending into the sliding shell 403 is slidably connected to the housing 401, meshing with the worm wheel 408. The ice storage mechanism 3 is slidably connected inside the sliding shell 403. The lifting mechanism 4 also includes a top plate 406, which is fixedly connected to the top of the toothed plate 405. The ice blocks inside the material bin 301 act as a guide for the aluminum alloy wheel. When cooling the hub, the highest point of the material box 301 can be aligned with the highest point of the hub. Then, the crank handle 402 can be rotated periodically, causing the worm gear 407 to rotate. As the worm gear 407 rotates, the worm wheel 408 rotates. Since the worm wheel 408 meshes with the toothed plate 405, the toothed plate 405 gradually slides down, further causing the top plate 406 to slide down, thus lowering the water tank 302. This achieves layer-by-layer cooling of the aluminum alloy hub. Reversing the crank handle 402 raises the material box 301, allowing for layer-by-layer cooling of the aluminum alloy hub as well.

[0033] The ice storage mechanism 3 includes a water tank 302. The water tank 302, extending into the sliding shell 403, is slidably connected to the operating table 1. Multiple support rods 304 are fixed inside the water tank 302. A material box 301, which abuts against the support rods 304, is placed inside the water tank 302. The water tank 302 abuts against the top plate 406. The ice storage mechanism 3 also includes a water pipe 303, which is connected to the side wall of the water tank 302. The lifting mechanism 4 also includes a side groove 404, which is formed on the side wall of the sliding shell 403. The water pipe 303 is slidably connected to the side groove 404. The air-cooling mechanism 2 includes a slide groove 201, which is formed on the operating table 1. A slide seat 204 is slidably connected to the slide groove 201, and a threaded connection is made to the operating table 1. A lead screw 203 rotates between the slide block 204 and a fan 202 is installed on the slide block 204. After the aluminum alloy wheel hub is placed, ice is added to the inside of the material box 301. The ice can lower the temperature of the surrounding air. The fan 202 is then turned on, which blows cold air towards the wheel hub, improving the cooling efficiency. The lead screw 203 can be rotated to make the slide block 204 slide on the slide groove 201. The closer the fan 202 is to the material box 301, the faster the cold air flows, which can also improve the air cooling efficiency. As the air flows and the ice melts due to heat absorption, the ice water flows from the material box 301 to the inside of the water receiving tank 302. The switch on the water pipe 303 is then turned on to process the ice water and prevent cold water from flowing to the bottom of the operating table 1 and causing pollution.

[0034] Specifically, the placement mechanism 5 includes a rotating shaft 503, which is rotatably connected to the opening on the surface of the operating table 1. An outer frame 501 is rotatably connected to the rotating shaft 503, and a placement plate 502 is fixedly connected inside the outer frame 501. A slot 504 is provided on the side wall of the outer frame 501, and a locking post 505 is slidably connected to the operating table 1. A holding spring 506 is clamped between the locking post 505 and the operating table 1. The locking post 505 engages with the slot 504. The placement plate 5... The surface of the 02 plate has holes at equal intervals, and the surface of the placement plate 502 has grooves. The driving mechanism 6 includes two limiting plates 601. The two limiting plates 601 are fixedly connected to the operating table 1. A pull frame 602 is slidably connected to the two limiting plates 601. A roller 605 is rotatably connected to the pull frame 602. Pressure grooves 604 are obliquely opened on both sides of the outer frame 501. The roller 605 is rotatably connected to the pressure grooves 604. A pedal 603 is fixed to the pull frame 602. After casting, the aluminum alloy wheel hub is placed onto the placement plate 502 using a lifting device. The placement plate 502 has grooves to facilitate the placement of the wheel hub. At this time, the locking post 505 and the locking groove 504 are engaged, and the aluminum alloy wheel hub will not roll. After the aluminum alloy wheel hub has cooled down, the locking post 505 is pulled away from the operating table 1, and the spring 506 contracts. Further, the locking post 505 separates from the locking groove 504. At the same time, the pedal 603 is stepped on, which makes the pull frame 602 slide up and down the limiting plate 601. Furthermore, since the outer frame 501 has an inclined pressure groove 604 on its side wall, the roller 605 rolls inside the pressure groove 604 when the pull frame 602 slides down. This allows the placement plate 502 to rotate around the pivot 503, thus achieving rapid unloading and saving effort. A conveying device can be installed at the bottom of the placement plate 502 to transfer the cooled aluminum alloy wheel hub.

[0035] In use, the present invention firstly involves placing the aluminum alloy wheel hub onto the placement plate 502 after casting using a lifting device. The placement plate 502 has grooves to facilitate the placement of the wheel hub. At this time, the locking post 505 and the locking groove 504 are engaged, and the aluminum alloy wheel hub will not roll. After the aluminum alloy wheel hub has cooled down, the locking post 505 is pulled away from the operating table 1, and the spring 506 retracts, further separating the locking post 505 from the locking groove 504. At the same time, the pedal 603 is stepped on, which enables the pull frame 602 to slide down the limiting plate 601. Furthermore, since the outer frame 501 has an inclined pressure groove 604 on its side wall, the roller 605 rolls inside the pressure groove 604 when the pull frame 602 slides down, thereby enabling the placement plate 502 to rotate around the pivot 503 as the fulcrum, thus achieving rapid unloading and saving effort. A conveying device can be installed at the bottom of the placement plate 502 to transfer the cooled aluminum alloy wheel hub.

[0036] Then, after placing the aluminum alloy wheel hub, ice is added to the inside of the material box 301. The ice can lower the temperature of the surrounding air. The fan 202 is then turned on, which blows cold air towards the wheel hub, improving the cooling efficiency. The screw 203 can be rotated to make the slide 204 slide on the slide groove 201. The closer the fan 202 is to the material box 301, the faster the cold air flows, which can also improve the air cooling efficiency. As the air flows and the ice melts due to heat absorption, the ice water flows from the material box 301 to the inside of the water receiving tank 302. The switch on the water pipe 303 is then turned on to process the ice water and prevent cold water from flowing to the bottom of the operating table 1 and causing pollution.

[0037] Finally, when cooling the aluminum alloy wheel hub with the ice blocks inside the material box 301, the highest point of the material box 301 can be aligned with the highest point of the wheel hub. Then, the crank handle 402 can be turned periodically, which drives the worm gear 407 to rotate. As the worm gear 407 rotates, it drives the worm wheel 408 to rotate. Since the worm wheel 408 meshes with the toothed plate 405, as the worm wheel 408 rotates, the toothed plate 405 can gradually slide down, which in turn drives the top plate 406 to slide down, thereby lowering the water tank 302. This achieves the cooling of the aluminum alloy wheel hub layer by layer. Turning the crank handle 402 in the opposite direction raises the material box 301, which can also cool the aluminum alloy wheel hub layer by layer.
