Abstract

An aluminum rod casting apparatus includes a liquid inlet, a casting part at the outlet end of the liquid inlet, a bottom support mechanism at the lower end of the casting part, and a bottom insertion mechanism at the upper end of the casting part. Multiple aluminum rods are located at the lower end of the bottom insertion mechanism, with the lower ends of the aluminum rods passing through the casting part. The bottom insertion mechanism is used to periodically insert or withdraw the aluminum rods from the casting part. The liquid inlet facilitates the flow of molten aluminum, ensuring that the molten aluminum enters the casting part. By providing multiple small aluminum rods of the same composition, it provides homogeneous nuclei for the aluminum rod during cooling and forming, thus facilitating grain formation.

Description

Technical Field

[0001] This invention relates to the field of aluminum rod casting technology, and more particularly to an aluminum rod casting apparatus. Background Technology

[0002] The rods used for aluminum profile extrusion are obtained through casting. Currently, cast aluminum rods often suffer from insufficient cooling, resulting in coarse grains in the central area. This leads to a significant decrease in the mechanical strength of the aluminum profiles during extrusion. Furthermore, during processing, the molten aluminum is prone to oxidation due to the lack of a protective atmosphere, affecting the quality of the rods. Additionally, slag from the molten aluminum cannot be removed during casting, causing it to enter the rods and form inclusions and other defects, further impacting their quality. Summary of the Invention

[0003] This invention provides an aluminum rod casting apparatus to overcome the shortcomings of the prior art, thereby refining the grains inside the aluminum rod and improving the quality of the cast aluminum rod. At the same time, it can avoid the impact of slag and other materials on the quality of the aluminum rod during casting, and also reduces the formation of oxides, making it highly practical.

[0004] In order to achieve the objectives of this invention, the following technologies are proposed:

[0005] An aluminum rod casting apparatus includes a liquid inlet, a casting part at the outlet end of the liquid inlet, a bottom support mechanism at the lower end of the casting part, and a bottom insertion mechanism at the upper end of the casting part. Multiple aluminum rods are provided at the lower end of the bottom insertion mechanism, with the lower ends of the aluminum rods passing through the casting part. The bottom insertion mechanism is used to periodically insert or withdraw the aluminum rods from the casting part. The liquid inlet facilitates the flow of molten aluminum, ensuring that the aluminum can enter the casting part. During the flow of aluminum, it can also filter slag and other impurities, thus preventing the presence of slag and other impurities from affecting the quality of the aluminum rod. By providing multiple small aluminum rods of the same composition, homogeneous nuclei are provided for the forming of the aluminum rod during cooling and shaping, facilitating grain formation. Furthermore, the molten aluminum rod grains are dispersed in the molten pool, allowing the aluminum to nucleate and grow using these dispersed aluminum grains, thereby forming a fine crystal structure. The periodic movement of the insertion mechanism provides time for the gradual melting of the aluminum rod, thus facilitating the entry of the aluminum rod grains into the molten pool, rather than in a rod-shaped structure or a semi-molten form, thereby improving the quality of the aluminum rod to some extent.

[0006] Furthermore, the liquid inlet component includes an outer block with a flow guide formed on it and a liquid inlet groove formed thereon. The liquid inlet groove is used to receive molten aluminum. The flow guide has a U-shaped flow channel and a filter element. Both the outer block and the flow guide are made of refractory material. The liquid inlet provides a cavity for pouring in molten aluminum, while the U-shaped flow channel guides the molten aluminum into the casting. The use of refractory material improves its service life.

[0007] Furthermore, the filter element includes a U-shaped filter plate passing through a U-shaped guide channel. The U-shaped filter plate has multiple perforations and is made of refractory material. An upper plate is located at the top of the U-shaped filter plate, above the guide element. Side plates extend downwards from both ends of the upper plate, located outside the guide element. An L-shaped element is located at the bottom of the side plates, with a lower extension rod at the bottom. A sleeve is fitted onto the lower end of the lower extension rod, which is mounted on the side wall of the guide element. A spring is fitted onto the upper end of the lower extension rod, located above the sleeve. A boss is mounted on the outer end of the sleeve, and a rotating plate is rotatably mounted on the outer end of the boss. An L-shaped fastener is located at the top of the rotating plate, with its vertical section engaged with the L-shaped element. The U-shaped filter plate filters the molten aluminum and blocks slag in the molten aluminum at the front end of the U-shaped guide channel, preventing slag from entering the casting and affecting the quality of the aluminum rod. The rotating L-shaped fastener acts on the L-shaped part, thus cooperating with the spring to fix the U-shaped filter plate. In this way, after casting is completed, the U-shaped filter plate can be pulled out to clear the holes on it.

[0008] Furthermore, the casting includes a casting block with a circular groove at its upper end and a U-shaped feed inlet on one side. A U-shaped guide channel connects to the U-shaped feed inlet. An upper extension column is located at the bottom of the circular groove, with multiple insertion holes on the column. An aluminum rod passes through these insertion holes. A forming circular groove is located at the lower end of the casting block, with multiple liquid inlet holes at its bottom. The lower ends of these liquid inlet holes connect to the forming circular groove, and a forming component is located at the lower end of the circular groove. The insertion holes facilitate the vertical movement of the aluminum rod. The liquid inlet holes allow molten aluminum to enter the lower end, thus forming the aluminum rod. Simultaneously, inserting the aluminum rod into the middle of the molten pool facilitates melting at the lower end of the rod, resulting in finer grains in the middle of the cast aluminum rod, thereby strengthening the rod through grain refinement.

[0009] A water inlet annular groove is formed on the upper outer periphery of the formed part. An annular plate is fitted over the water inlet annular groove, and a cooling water connecting pipe is connected to the annular plate. A first circular hole is formed on the formed part, and a second circular hole is formed at the lower end of the first circular hole. A conical hole is formed at the lower end of the second circular hole. A second conical hole is formed between the first and second circular holes, with the upper end of the conical hole being the smaller end. Multiple first liquid inlet holes are connected to the water inlet annular groove, with the inner end of each first liquid inlet hole located at the first circular hole. Multiple second liquid inlet holes are also connected to the water inlet annular groove, with the inner end of each second liquid inlet hole located on the second conical hole. The two first liquid inlet holes and the two second liquid inlet holes allow for rapid cooling of the aluminum rod, while the conical hole facilitates the outflow of cooling water, thus preventing the formation of holes inside the aluminum rod due to the presence of cooling water.

[0010] Furthermore, the cross-section of the water inlet annular groove is an isosceles trapezoid, with the width of the inner end being greater than the width of the outer end. This structural design ensures the pressure when cooling water is introduced, allowing cooling water to be sprayed out through both the first and second inlet holes, thus facilitating the cooling operation of the aluminum rod.

[0011] Furthermore, a slot is provided at the upper end of the forming groove, and a nitrogen inlet box passes through the slot. A central hole, the same size as the forming groove, is provided on the inner end of the nitrogen inlet box, and multiple air inlets are provided on the wall of the central hole. An air inlet pipe is connected to the nitrogen inlet box. This surrounding nitrogen inlet ensures that the upper end of the aluminum rod is enveloped in nitrogen, thus preventing oxidation of the molten aluminum. Simultaneously, the nitrogen inlet also carries away some heat, allowing the aluminum rod to cool rapidly.

[0012] Furthermore, the bottom support mechanism includes a pair of guide vertical rods, each with an mounting end plate at its upper and lower ends. The mounting end plates are installed on the wall of the casting shaft. U-shaped components are fitted onto the guide vertical rods, with sliders on the inner ends of the U-shaped components. The sliders are in close contact with the guide vertical rods. The inner ends of the U-shaped components are mounted on a movable plate, which is equipped with a mounting plate and a bottom support cover. A movable seat is mounted on the other end of the movable plate. A vertical plate is also installed on the casting shaft, with movable end seats mounted at both ends. A movable motor is mounted on the upper movable end seat, and the output shaft of the movable motor is connected to a movable lead screw, which is mounted on the movable seat. The bottom support cover, which allows for speed control, facilitates the control of the aluminum rod casting speed and the casting quality.

[0013] Furthermore, the lower insertion mechanism includes an upper plate mounted on the upper end of the frame, with multiple connecting guide rods extending downwards from the upper plate. The lower ends of the connecting guide rods are located on a lower plate, which is mounted on the lower end of the frame. A frame is mounted on the upper end of the upper plate, with guide rails mounted on both sides inside the frame. A movable frame is movably mounted on the guide rails, and multiple movable rods are located at the lower end of the movable frame. The movable rods pass through the upper plate, and movable bars are mounted on the inner side of the vertical section of the movable frame. The movable bars have multiple V-grooves. A drive seat is mounted on the upper plate, and a drive motor is mounted on the drive seat. A rotating disk is connected to the output shaft of the drive motor. The movable plate is equipped with multiple actuating levers. These levers act on the V-shaped groove to move the movable frame up and down. An upper movable plate is located at the lower end of each lever, and a pair of connecting rods are mounted on the upper movable plate. A lower movable plate is fitted onto each connecting rod, and a stop plate is located at the lower end of each connecting rod. A first spring is fitted onto the lower end of each connecting rod, positioned above the stop plate and below the lower movable plate. Multiple second springs are located between the upper and lower movable plates, and these second springs are fitted onto connecting guide rods. A connecting moving rod is located on the lower movable plate and passes through it. The actuating levers acting on the V-shaped groove cause the movable frame to reciprocate within the frame. As the movable frame moves, the aluminum rod reciprocates up and down, thereby refining the grains in the center of the aluminum rod. The placement of the first and second springs improves the smoothness of the shaking process and enhances the shaking capability of the aluminum rod, thereby facilitating the shaking of molten aluminum off the aluminum rod and providing sufficient nucleation sites for the casting of the aluminum rod.

[0014] Furthermore, a mounting bracket is installed at the lower end of the connecting rod, an upper end seat is mounted on the mounting bracket, an adjusting motor is mounted on the upper end seat, multiple middle support rods are provided at the lower end of the upper end seat, and a lower end seat is provided at the lower end of the middle support rods. The output shaft of the adjusting motor is connected to an adjusting screw, an adjusting seat is provided on the adjusting screw, multiple pairs of adjusting push rods are provided on the adjusting seat, and an adjusting disc is provided at the lower end of the adjusting push rod. By setting the adjusting screw, when the aluminum rod participates in the forming, the extension length of the aluminum rod can be controlled according to the melting speed of the aluminum rod, thereby ensuring that the extension length of the aluminum rod remains constant.

[0015] Furthermore, the adjusting disc is equipped with a central guide rod, the outer circumference of which has multiple guide grooves. A lower disc is located at the lower end of the central guide rod, and a placement groove is formed at the lower end of the lower disc. An embedded disc is placed in the placement groove, and the lower end of the embedded disc has a lower extending frustum with multiple screw holes. The upper end of the aluminum rod is screwed into these screw holes. Multiple rotating rods are rotatably mounted on the lower disc, and spiral grooves are formed on the outer wall of each rotating rod. Multiple pins are located on the circumference of the lower disc, and these pins pass through the spiral grooves. A limiting device is located at the lower end of each rotating rod. The limiting end plate has its inner end acting on the lower end of the embedded disk to limit its movement. The upper end of the rotating rod has a rotating pin, on which a movable disk is fitted. The movable disk is fitted onto the central guide rod. The outer circumference of the adjusting disk has a first protrusion, on which a connecting screw is rotatably mounted. A second protrusion is screwed onto the connecting screw, which is located on the movable disk. The lower end of the connecting screw has a third protrusion rotatably mounted on the outer circumference of the lower disk. The lower end of the connecting screw has a rotating cap. The aluminum rod is fixed by screws for easy fixation. Fixing the aluminum rod to the detachable embedded disk facilitates pre-processing by the operator. The rotatable limiting end plate, when pulled upwards, acts on the embedded disk, thus fixing the aluminum rod. The central guide rod guides the movement of the movable disk.

[0016] The advantages of the above technical solution are:

[0017] Compared with existing technologies, this invention facilitates the casting of aluminum rods by providing aluminum rods of the same composition. Furthermore, the melting of aluminum on the rod creates dispersed, homogeneous nucleation particles, thus refining the grain size within the aluminum rod. During casting, the molten pool is protected with nitrogen gas to prevent oxide formation. Secondly, it enables rapid cooling during aluminum rod forming, further refining the grain size within the aluminum rod. Attached Figure Description

[0031] like Figures 1-12 As shown, an aluminum rod casting device includes a liquid inlet 1, a casting part 2 is provided on the discharge end of the liquid inlet 1, a bottom support mechanism 3 is provided at the lower end of the casting part 2, a bottom insertion mechanism 4 is provided at the upper end of the casting part 2, and multiple aluminum rods 443 are provided at the lower end of the bottom insertion mechanism 4. The lower ends of the aluminum rods 443 pass through the casting part 2. The bottom insertion mechanism 4 is used to drive the aluminum rods 443 to periodically insert or withdraw from the casting part 2.

[0032] In this embodiment, during operation, the operator first processes the aluminum rod 443. During processing, the aluminum rod 443 needs to be repeatedly stretched. Through repeated stretching, when the aluminum rod participates in casting, the stress generated by the stretching is continuously released during the melting process, causing the aluminum rod to vibrate slightly. This increases the probability of aluminum nucleation and refines the grains of the aluminum rod. Simultaneously, when the aluminum rod 443 is inserted into the molten aluminum pool, it facilitates rapid heat transfer, allowing the molten pool to cool quickly and further refining the internal grains of the aluminum rod. During casting, the aluminum rod 443 reciprocates under the drive of the lower insertion mechanism 4, allowing it to penetrate into the crystallization zone of the molten pool for melting. The molten grains then provide multiple nucleation points for the aluminum rod grains, further refining the internal grains of the formed aluminum rod.

[0033] In this embodiment, the aluminum rod 443 is first fixed on the lower insertion mechanism 4. Then, the molten aluminum is introduced into the casting 2 through the liquid inlet 1 and cast in the casting 2. The bottom support mechanism 3 supports the aluminum rod, thereby controlling the casting speed of the aluminum rod. During the casting process, the aluminum rod 443 moves up and down through the lower insertion mechanism 4.

[0034] The liquid inlet component 1 includes an outer block 100, on which a flow guide 102 is formed. An inlet groove 101 is formed on the outer block 100 to receive molten aluminum.

The filter element includes a U-shaped filter plate 104 passing through the U-shaped flow guide groove 103. The U-shaped filter plate 104 has multiple holes and is made of refractory material. An upper plate 105 is provided at the upper end of the U-shaped filter plate 104, located above the flow guide 102.

A lower extension rod 108 is provided, and a sleeve 109 is fitted at the lower end of the lower extension rod 108. The sleeve 109 is installed on the side wall of the guide member 102. A spring 110 is fitted at the upper end of the lower extension rod 108. The spring 110 is located at the upper end of the sleeve 109. A boss 111 is installed at the outer end of the sleeve 109. A rotating plate 112 is rotatably provided at the outer end of the boss 111. An L-shaped fastener 113 is provided at the upper end of the rotating plate 112. The vertical section of the L-shaped fastener 113 is engaged with the L-shaped member 107.

[0035] When injecting molten aluminum, the molten aluminum is poured into the inlet tank 101. Then, the molten aluminum enters the casting 2 through the U-shaped guide channel 103. When the molten aluminum flows, the U-shaped filter plate 104 filters the slag inside to prevent the slag from entering the aluminum rod and thus forming inclusions and other defects in the aluminum rod.

[0036] When cleaning the U-shaped filter plate 104, first press down on the U-shaped filter plate 104 and then rotate the L-shaped fastener 113 outward. Then, the operator pulls out the U-shaped filter plate 104 and clears the holes.

[0037] The casting 2 includes a casting block 215. A circular groove 202 is provided at the upper end of the casting block 215. A U-shaped feed inlet 200 is provided on one side of the casting block 215. A U-shaped guide channel 103 is connected to the U-shaped feed inlet 200. An upper extension column 203 is provided at the bottom of the circular groove 202. Multiple insertion holes 205 are provided on the upper extension column 203. An aluminum rod 443 passes through the insertion holes 205. A forming circular groove 216 is provided at the lower end of the casting block 215. Multiple liquid inlet holes 204 are provided at the bottom of the circular groove 202. The lower end of the liquid inlet holes 204 is connected to the forming circular groove 216. A forming part 207 is provided at the lower end of the circular groove 202. A water inlet annular groove 208 is provided on the outer periphery of the upper end of the molded part 207. An annular plate 209 is provided on the outer sleeve of the water inlet annular groove 208. A cooling water connecting pipe is connected to the annular plate 209.

The upper end of the conical hole 214 is the smaller end. The upper end of the second conical hole is the smaller end. A plurality of first liquid inlet holes 211 are connected to the water inlet annular groove 208. The inner end of the first liquid inlet hole 211 is located at the first circular hole 210. A plurality of second liquid inlet holes 212 are also connected to the water inlet annular groove 208. The inner end of the second liquid inlet hole 212 is located on the second conical hole. The cross-section of the water inlet annular groove 208 is an isosceles trapezoid, with the width of the inner end being greater than the width of the outer end. A slot is provided at the upper end of the formed circular groove 216, through which a nitrogen inlet box 206 passes. A central hole, the same size as the formed circular groove 216, is provided at the inner end of the nitrogen inlet box 206. Multiple air inlet holes are provided on the wall of the central hole, and an air inlet pipe is connected to the nitrogen inlet box 206.

[0038] During casting, molten aluminum enters the circular groove 202 through the U-shaped feed port 200. Subsequently, the molten aluminum flows into the forming circular groove 216 through the liquid inlet 204. Before the molten aluminum flows downward, nitrogen is introduced into the nitrogen inlet box 206. The nitrogen enters the forming circular groove 216, thereby filling the upper part of the forming circular groove 216. The nitrogen can expel air, thereby preventing the molten aluminum from oxidizing and ensuring the quality of the aluminum rod after casting. The molten aluminum is rapidly cooled by the cooling liquid discharged from the first liquid inlet 211 and the second liquid inlet 212. The cooling water flows downward through the gap between the conical hole 214 and the aluminum rod.

[0039] The bottom support mechanism 3 includes a pair of guide vertical rods 300. The upper and lower ends of the guide vertical rods 300 are respectively provided with mounting end plates 301. The mounting end plates 301 are installed on the wall of the casting shaft. U-shaped parts 302 are respectively sleeved on the guide vertical rods 300.

The movable lead screw 309 is provided on the movable seat 310.

[0040] During casting, the bottom cover 305 is located at the lower end of the forming groove 216. When the lower end of the cast aluminum rod is placed on the bottom cover 305, the moving motor 308 is started. Driven by the moving motor 308, the moving screw 309 rotates. When the moving screw 309 rotates, it will drive the moving seat 310 to move. The movement of the moving seat 310 will drive the aluminum rod to move downward until the aluminum rod is formed.

[0041] The lower insertion mechanism 4 includes an upper plate 400 mounted on the upper end of the frame.

The lower movable plate 444 is provided with a connecting moving rod 417, which passes through the lower movable plate 444. A mounting bracket 418 is installed at the lower end of the connecting rod 417. An upper end seat 419 is installed on the mounting bracket 418. An adjusting motor 422 is installed on the upper end seat 419. Multiple middle support rods 420 are provided at the lower end of the upper end seat 419. A lower end seat 421 is provided at the lower end of the middle support rods 420. An adjusting screw 423 is connected to the output shaft of the adjusting motor 422. An adjusting seat 424 is provided on the adjusting screw 423. Multiple pairs of adjusting push rods 425 are provided on the adjusting seat 424. An adjusting plate 426 is provided at the lower end of the adjusting push rod 425.The adjusting disc 426 is provided with a central guide rod 427. Multiple guide grooves 428 are provided on the outer periphery of the central guide rod 427. A lower disc 429 is provided at the lower end of the central guide rod 427. A placement groove is opened at the lower end of the lower disc 429, in which an embedded disc 441 is placed. A lower extended frustum 442 is provided at the lower end of the embedded disc 441. Multiple screw holes are opened on the lower extended frustum 442. The upper end of an aluminum rod 443 is screwed into the screw holes. Multiple rotating rods 432 are rotatably mounted on the lower disc 429. Spiral grooves 433 are opened on the outer wall of the rotating rods 432. Multiple pins 434 are provided on the periphery of the lower disc 429, and the pins 434 pass through the spiral grooves 433. A limiting end plate 440 is provided at the lower end of the rotating rods 432. The inner end of the limiting end plate 440 acts on the lower end of the embedded disk 441 to limit the embedded disk 441. The upper end of the rotating rod 432 is provided with a rotating pin 431, and a movable disk 430 is sleeved on the rotating pin 431. The movable disk 430 is sleeved on the middle guide rod 427. The outer periphery of the adjusting disk 426 is provided with a first protrusion 438. A connecting screw 437 is rotatably provided on the first protrusion 438. A second protrusion 439 is screwed onto the connecting screw 437. The second protrusion 439 is provided on the movable disk 430.

The lower end of the connecting screw 437 is provided with a rotating cap 436.

[0042] During operation, multiple aluminum rods 443 are first screwed onto the screw holes. Then, the embedded disc 441 is placed in the placement slot. Next, the operator rotates the connecting screw 437 by rotating the cap 436, which causes the movable disc 430 to move upward under the guidance of the middle guide rod 427. Driven by the movable disc 430, the limiting end plate 440 moves upward. When the limiting end plate 440 moves upward, the rotating rod 432 rotates inward under the action of the pin 434, and finally limits the embedded disc 441 through the limiting end plate 440. After completion, the drive motor 406 is started. Driven by the drive motor 406, the rotating disk 407 rotates. The rotation of the rotating disk 407 causes the actuating rod 408 to act on the V-shaped groove 410, thereby causing the movable frame 404 to move up and down within the frame 403. When the movable frame 404 moves, it drives the upper movable disk 412 and the lower movable disk 444 to move up and down reciprocally. When the upper movable disk 412 and the lower movable disk 444 vibrate up and down, the first spring 416 and the second spring 413 can improve the vibration capability of the aluminum rod 443, thereby facilitating the melting of the aluminum rod 443 and allowing the molten aluminum to enter the melting and crystallization zone, thus facilitating the forming of the aluminum rod. Furthermore, after the aluminum rod 443 has been reciprocating for a period of time, the adjusting motor 422 is started, and the adjusting screw 423 is rotated under the drive of the adjusting motor 422. Under the rotation of the adjusting screw 423, the adjusting seat 424 moves downward, and under the drive of the adjusting seat 424, the aluminum rod 443 is always inserted into the melting pool at a certain length.

Obviously, those skilled in the art can make various modifications and variations to the present invention without departing from the spirit and scope of the present invention.
