DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0023] Embodiment 1 like Figure 1-8 As shown, a continuous casting device for producing aluminum ingots described in an embodiment of the present invention includes a body 1, a shaping component 3 and a furnace 2 for heating aluminum products into aluminum liquid, wherein the furnace 2 is fixedly mounted on the body 1, and the shaping component 3 is used to inject the aluminum liquid into aluminum ingots, and the shaping component 3 includes: a No. 1 rod 31 rotatably mounted on the body 1, and a plurality of mounting seats 32 are rotatably mounted on the No. 1 rod 31; a mold 33 detachably mounted on the mounting seat 32; two insertion rods 34 slidably mounted on the mold 33, and a cover plate 35 is mounted on the insertion rod 34, and a plurality of air holes 36 are opened on the cover plate 35; a circular ring 37 mounted on the cover plate 35, and a plurality of No. 1 air inlets 38 are opened on the circular ring 37, and the total flow area of ​​the air holes 36 is greater than the total flow area of ​​the No. 1 air inlets 38.

[0024] Specifically, the existing device uses the impact method to vibrate the liquid aluminum in the mold 33, thereby expelling the air in the liquid aluminum. However, the liquid vibrates during the process of cooling and solidifying into an aluminum ingot, which affects the stability and structural integrity of the aluminum ingot. The position of the mold 33 below the melting furnace 2 is taken as the working position; Before working, the cover plate 35 is connected to the vacuum pump. During working, the aluminum product is added into the melting furnace 2 and heated until the aluminum product is melted into liquid aluminum. The melting furnace 2 is controlled to pour the liquid aluminum into the mold 33 on the working station. After the pouring is completed, the No. 1 rod 31 is controlled to rotate clockwise. The rotation of the No. 1 rod 31 drives the mounting seat 32 and the mold 33 to rotate clockwise, so that the next mold 33 and the mounting seat 32 that are not filled with liquid aluminum are transferred to the working station, and the mold 33 filled with liquid aluminum leaves the working station. During the process of the mold 33 leaving the working station, the vacuum pump is controlled to start The cover plate 35 is moved so that the air under the cover plate 35 is sucked away from the air vents 36. At the same time, the plunger 34 is controlled to move downward. The downward movement of the plunger 34 drives the cover plate 35 and the ring 37 to move downward synchronously until the lower surface of the ring 37 is flush with the upper surface of the mold 33. At this time, the outside air enters the interior of the mold 33 from the No. 1 air inlet 38 and is discharged from the air vents 36, so that the air flow rate above the liquid aluminum in the mold 33 is accelerated, so as to facilitate the rapid cooling of the liquid aluminum. At the same time, since the total flow area of ​​the No. 1 air inlet 38 is smaller than the total flow area of ​​all the air vents 36, the air above the liquid aluminum in the mold 33 is increased. The amount of air entering the mold 33 from the first air inlet 38 is small, while the amount of air discharged from the mold 33 from the air vent 36 is large. Therefore, the interior of the mold 33 is maintained at a constant low pressure state, so that the air in the liquid aluminum can be discharged. After the liquid aluminum cools and solidifies to form an aluminum ingot, the plunger 34 can be controlled to move upward, so that the cover plate 35 and the ring 37 move upward synchronously, and then the mounting seat 32 is controlled to rotate, so that the mold 33 tilts downward, and the aluminum ingot falls off from the inside of the mold 33 under the action of its own gravity, thus realizing the casting of the aluminum ingot. During the process, the No. 1 round rod rotates, so that the mold 33 moves to the working station again, and this cycle is carried out to realize the continuous casting process of the aluminum ingot; by setting the mold 33 component, the flow of air above the liquid aluminum can be accelerated, the liquid aluminum can be quickly cooled, and the work efficiency is improved. The total flow area of ​​the air vents 36 is controlled to be greater than the total flow area of ​​the No. 1 air inlet 38, so that the interior of the mold 33 is maintained at a constant low-pressure state, and the air inside the liquid aluminum can be discharged. Compared with the vibration form, this method has less effect on the stability and structural integrity of the aluminum ingot.

[0025] like Figure 1 , 4As shown in Figure 5, the shaping component 3 also includes: a No. 1 cavity 39 opened on the mold 33, the insertion rod 34 adopts a hollow mode, and the No. 1 cavity 39 is connected with the cover plate 35 through the insertion rod 34; an air outlet 310 opened on the mold 33; and a number of No. 2 air inlets 311 opened on the surface of the mold 33, and the outside air enters the No. 1 cavity 39 from the No. 2 air inlets 311 and is discharged from the air outlet 310.

[0026] Specifically, before work, the air outlet 310 of the mold 33 is connected to the vacuum pump. After the liquid aluminum is poured into the mold 33, the vacuum pump is controlled to evacuate air so that part of the air outside the mold 33 enters the cavity through the No. 2 air inlet 311 and is discharged from the air outlet 310, and part of the air enters the interior of the mold 33 from the No. 1 air inlet 38, enters the cavity from the vent, and is then discharged from the air outlet 310; by setting the No. 2 air inlet 311, the air around the liquid aluminum can flow quickly, further accelerating the solidification process of the liquid aluminum.

[0027] like Figure 1 , 4 As shown in FIG. 5 , the shaping component 3 also includes: a groove 312 opened on the mold 33, the size of the groove 312 is consistent with the ring 37; a baffle 313 slidably installed inside the mold 33, the baffle 313 is used to block external air from entering the No. 1 cavity 39 from the No. 2 air inlet 311.

[0028] Specifically, after the liquid aluminum solidifies into an aluminum ingot, the control rod 34 is continued to move downward, and the downward movement of the rod 34 drives the cover plate 35 and the ring 37 to move downward synchronously until the ring 37 is completely inserted into the groove 312. At the same time, the baffle 313 is controlled to move downward, so that the No. 2 air inlet 311 is blocked by the baffle 313. At this time, only the interior of the mold 33 is connected to the vacuum pump through the vent hole. Therefore, the pressure in the mold 33 gradually decreases, which can give the aluminum ingot an upward pulling force, which helps the subsequent aluminum ingot to fall off from the mold 33 smoothly by gravity, thereby improving the problem of adhesion between the aluminum ingot and the mold 33.

[0029] like Figure 1 , 4As shown in FIG. 5 , the shaping component 3 also includes: a No. 1 telescopic rod 314 fixedly mounted on the cover plate 35; a No. 1 pressure sensor 315 fixedly mounted on the mounting seat 32, the No. 1 pressure sensor 315 being used to detect the volume of the liquid poured into the mold 33, and transmit the data to the controller, and the controller controls the length of the No. 1 telescopic rod 314 extending into the mold 33; a No. 2 pressure sensor 316 fixedly mounted on the movable end of the No. 1 telescopic rod 314, the No. 2 pressure sensor 316 being used to detect whether the solidified aluminum ingot moves upward.

[0030] Specifically, while controlling the baffle 313 to block the No. 2 air inlet 311, controlling the No. 1 telescopic rod 314 to extend downward, the downward extension of the No. 1 telescopic rod 314 drives the No. 2 pressure sensor 316 to move downward synchronously until the No. 2 pressure sensor 316 is located slightly above the aluminum ingot. After the pressure in the mold 33 drops, if the aluminum ingot moves upward, the No. 2 pressure sensor 316 can be triggered, otherwise the No. 2 pressure sensor 316 has no data feedback; the movement of the aluminum ingot is detected by the No. 2 pressure sensor 316 to determine whether additional assistance is needed in the process of the aluminum ingot falling off the mold 33.

[0031] like Figure 2 , 6 , 7, and 8, an inclined plate 4 is fixedly installed on the machine body 1, and the solidified aluminum ingot falls off from the mold 33 and falls on the inclined plate 4. A pump body 5 is fixedly installed on the No. 1 rod 31, and the No. 1 rod 31 adopts a hollow structure. The pump body 5 is connected with the interior of the No. 1 rod 31. A disc 6 is fixedly installed on the machine body 1, and a notch is set at the inclined plate 4 to facilitate the rotation of the mounting seat 32. A No. 1 annular block 7 and a No. 2 annular block 8 are fixedly installed on the upper surface of the disc 6. The No. 1 annular block 7 and the upper surface of the mounting seat 32 are connected. The mounting seat 32 is rotatably connected to the No. 1 rod 31 through the rotating rod 9. The two ends of the rotating rod 9 are respectively fitted with the No. 1 annular block 7 and the No. 2 annular block 8. The rotating rod 9 divides the space between the No. 2 annular block 8 and the No. 1 annular block 7 into a plurality of closed No. 2 cavities 10. The No. 2 annular block 8 is provided with a plurality of No. 3 air inlets 11. The mounting seat 32 is provided with a No. 4 air inlet 12. The No. 3 air inlet 11 is connected to the No. 2 cavity 10 and the No. 4 air inlet 12.

[0032] Specifically, the pump body 5 adopts a suction pump. Figure 3 The position of the mold 33 above the middle inclined plate 4 is the disengagement position, and correspondingly, Figure 6In the figure, the upper left part not in contact with the No. 1 ring block 7 is the disengagement position, and the lower left part half in contact with the No. 1 ring block 7 is the working position. The No. 3 air inlet 11 is not provided in the working position, the disengagement position and the position between the No. 2 ring block 8; in the initial state, the mold 33 is at the working position. When working, the pump body 5 is started to generate suction force. After the liquid aluminum is poured into the mold 33, the No. 1 rod 31 rotates counterclockwise (with Figure 6 As an example, the rotation of the No. 1 rod 31 drives the mounting seat 32 and the rotating rod 9 to move synchronously until both rotating rods 9 are in contact with the No. 1 annular block 7. At this time, the No. 2 cavity 10 is formed between the rotating rod 9 and the No. 1 annular block 7 and the No. 2 annular block 8. At the same time, the No. 2 cavity 10 is connected to the No. 1 rod 31 through the No. 3 air inlet 11. Therefore, the pump body 5 can generate suction force on the air around the mold 33 through the No. 2 cavity 10 and the No. 4 air inlet 12, so as to cool down and discharge the liquid aluminum in the mold 33. The action of the air causes the rod 31 to continue to rotate, driving the mounting seat 32 and the mold 33 to move to the disengagement station. The liquid aluminum solidifies into an aluminum ingot, and the rotating rod 9 is not in contact with the No. 1 annular block 7, and there is no No. 3 air inlet 11 on the No. 2 annular block 8. Therefore, the No. 4 air inlet 12 is not connected to the pump body 5. At this time, the rotating rod 9 can be rotated to make the mold 33 tip over, and the aluminum ingot in the mold 33 falls onto the inclined plate 4, thus completing the demoulding action. Only one pump body 5 is needed to control multiple molds 33, which is convenient to use.

[0033] like Figure 5 As shown, the mold 33 assembly also includes a No. 1 spring 317 fixedly installed in the No. 1 cavity 39 , one end of the No. 1 spring 317 is connected to the mold 33 , and the other end of the No. 1 spring 317 is connected to the insertion rod 34 .

[0034] Specifically, by setting the No. 1 spring 317, after the mold 33 leaves the working station, a suction force is generated in the cavity, causing the insertion rod 34 and the cover plate 35 to move downward until the lower surface of the ring 37 on the cover plate 35 is flush with the upper surface of the mold 33. At this time, the No. 1 spring 317 contracts. When the mold 33 is transferred to a station between the separation station and the working station, the cavity is not connected to the pump body 5. At this time, there is no suction force in the cavity, and the insertion rod 34 and the cover plate 35 return to their original positions under the action of the elastic force of the No. 1 spring 317, which is convenient to use.

[0035] like Figure 1 , 4 As shown, it also includes: a second telescopic rod 13 fixedly mounted on the body 1; an inclined panel 14 fixedly mounted on the second telescopic rod 13, the inclined panel 14 is located within the moving range of the cover plate 35, and the inclined panel 14 is used to press the cover plate 35 into the groove 312.

[0036] Specifically, the second telescopic rod 13 adopts a telescopic structure to adapt to the heights of different molds 33. The position of the mold 33 away from the work station and away from the working station is the suction station. During the process of transferring the mold 33 and the cover plate 35 to the suction station, the cover plate 35 contacts the inclined surface of the inclined plate 14, so that the cover plate 35 and the insertion rod 34 gradually move downward. When the mold 33 is in the suction station, the ring 37 on the cover plate 35 is inserted into the groove 312.

[0037] like Figure 7 , 8 As shown, it also includes a No. 3 annular block 15 rotatably mounted on the disc 6, and a No. 5 air inlet 16 is arranged on the No. 3 annular block 15. The No. 5 air inlet 16 is staggered with the No. 3 air inlet 11. The No. 3 annular block 15 rotates so that the gap between one of the No. 5 air inlet 16 and the No. 3 air inlet 11 increases or decreases, and the gaps between the remaining No. 5 air inlet 16 and the No. 3 air inlet 11 change in the opposite direction.

[0038] Specifically, after the No. 1 telescopic rod 314 is extended downward and there is no data feedback from the No. 2 pressure sensor 316, the No. 3 annular block 15 is controlled to rotate. The No. 3 annular block 15 rotates, so that the gap between the No. 5 air inlet 16 and the No. 3 air inlet 11 of the remaining stations is reduced, and the gap between the No. 5 air inlet 16 and the No. 3 air inlet 11 on the detachment station is increased, so that the suction force of the pump body 5 allocated to the mold 33 at the detachment station is increased while the suction force at other positions is reduced under the condition that the suction force remains unchanged, so as to avoid the problem that the mold 33 and the aluminum ingot cannot be demolded.

[0039] like Figure 4 As shown, the plurality of No. 2 air inlets 311 on the surface of the mold 33 are distributed into a plurality of groups, and each group of No. 2 air inlets 311 is distributed obliquely downward along the outer surface of the mold 33 .

[0040] Specifically, by distributing the plurality of second air inlets 311 obliquely, it is convenient for the external cold air to first contact the side walls at various heights of the liquid aluminum after entering the cavity, so as to facilitate the uniform cooling of the liquid aluminum.

[0041] like Figure 5 As shown, the baffle 313 contains a protrusion, and the insert rod 34 drives the ring 37 to move into the groove 312, and can drive the baffle 313 to move downward synchronously through the protrusion. A No. 2 spring 17 is installed between the baffle 313 and the mold 33.

[0042] Specifically, in the process of the insertion rod 34 driving the ring 37 to move into the groove 312, the insertion rod 34 can push the baffle 313 to move downward synchronously, that is, to block the No. 2 air inlet 311. At this time, the No. 2 spring 17 is compressed. When the mold 33 is transferred between the working station and the disengagement station, the baffle 313 returns to its original position under the action of the elastic force of the No. 2 spring 17, that is, the No. 2 air inlet 311 is opened again, which is convenient to use.

[0043] Working principle: during operation, aluminum products are added into the melting furnace 2 and heated until the aluminum products are melted into liquid aluminum. The melting furnace 2 is controlled to pour the liquid aluminum into the interior of the mold 33 on the working station. After the pouring is completed, the No. 1 rod 31 is controlled to rotate clockwise. The rotation of the No. 1 rod 31 drives the mounting seat 32 and the mold 33 to rotate clockwise, and the mold 33 filled with liquid aluminum leaves the working station until the two rotating rods 9 are in contact with the No. 1 annular block 7. At this time, a No. 2 cavity 10 is formed between the rotating rod 9 and the No. 1 annular block 7 and the No. 2 annular block 8. At the same time, the No. 2 cavity 10 is connected to the No. 1 rod 31 through the No. 3 air inlet 11. Therefore, the pump body 5 can generate suction force on the air in the environment around the mold 33 through the No. 2 cavity 10 and the No. 4 air inlet 12. Suction is generated, so the insert rod 34 and the cover plate 35 move downward until the lower surface of the ring 37 on the cover plate 35 is flush with the upper surface of the mold 33. At this time, the No. 1 spring 317 contracts, and the outside air enters the interior of the mold 33 from the No. 1 air inlet 38 and is discharged from the air vent 36, so that the air flow rate above the liquid aluminum in the mold 33 is accelerated to facilitate the rapid cooling of the liquid aluminum. At the same time, since the area of ​​all the No. 1 air inlets 38 is smaller than the area of ​​all the air vents 36, the pressure inside the mold 33 is smaller than the external atmospheric pressure, so the air in the liquid aluminum can be discharged. During the transfer of the mold 33 and the cover plate 35 to the suction station, the cover plate 35 contacts the inclined surface of the inclined plate 14, so that the cover plate 35 and the insert rod 3 4 gradually moves downward. When the mold 33 is in the suction station, the liquid aluminum solidifies into an aluminum ingot. The ring 37 on the cover plate 35 is inserted into the groove 312. When the insert rod 34 drives the ring 37 to move into the groove 312, the insert rod 34 can push the baffle plate 313 to move downward synchronously, that is, to achieve the action of blocking the No. 2 air inlet 311, and control the No. 1 telescopic rod 314 to extend downward. The No. 1 telescopic rod 314 extends downward to drive the No. 2 pressure sensor 316 to move downward synchronously until the No. 2 pressure sensor 316 is located at a position slightly above the aluminum ingot. After the pressure in the mold 33 drops, if the aluminum ingot moves upward, the No. 2 pressure sensor 316 can be triggered. Otherwise, the No. 2 pressure sensor 316 has no data feedback. If the No. 2 pressure sensor 316 The force sensor 316 has no data feedback, and controls the rotation of the No. 3 annular block 15. The rotation of the No. 3 annular block 15 reduces the gap between the No. 5 air inlet 16 and the No. 3 air inlet 11 of the remaining stations, and increases the gap between the No. 5 air inlet 16 and the No. 3 air inlet 11 on the detachment station, so that the pump body 5 increases the suction force allocated to the mold 33 on the detachment station while the suction force remains unchanged, and the suction force at other positions decreases until the aluminum ingot contacts the No. 2 pressure sensor 316. The No. 1 rod 31 continues to rotate, driving the mounting seat 32 and the mold 33 to transfer to the detachment station. The liquid aluminum solidifies into an aluminum ingot, the rotating rod 9 does not contact the No. 1 annular block 7, and there is no No. 3 air inlet 11 on the No. 2 annular block 8. Therefore, the No. 4 air inlet 12 is not connected to the pump body 5.Then the insert rod 34 and the cover plate 35 return to their original positions under the elastic force of the No. 1 spring 317. At this time, the rotating rod 9 can be rotated to make the mold 33 fall down, and the aluminum ingot in the mold 33 falls onto the inclined plate 4, which means that the casting of the aluminum ingot is completed. The No. 1 round rod rotates to move the mold 33 to the working station again, and this cycle is repeated to realize the continuous casting process of the aluminum ingot.
