[0041] Step 2: Pour molten aluminum metal into the mold for shaping: the mold closing cylinder 34 pushes the lower mold 35 upward so that the lower mold 35 and the upper mold 33 are fitted together. At this time, the metering valve is opened to allow a certain amount of molten metal to enter the cavity formed by the lower mold 35 and the upper mold 33 along the guide pipe 32 and the guide groove 331 to form an aluminum profile embryo.

[0042] Step three, discharge the bubbles in the molten metal: utilize the attraction between the first magnetic plate 43 and the second magnetic plate 431 to reduce the air pressure in the hot melt tank 2 so that the bubbles in the molten metal in the hot melt tank 2 can be quickly discharged upwards, and at the same time, a vibration effect is generated in the upper mold 33, so that the bubbles in the molten metal entering the casting cavity are quickly discharged upwards after being vibrated, which effectively improves the manufacturing quality of the aluminum profile metal.

[0043] Step 4: Cooling the molten aluminum metal in the mold: In the early stage of casting, the cooling is carried out through the cavity of the cooling groove 51, and after the aluminum profile casting is initially formed, the conduction cooling of the coolant is realized, so as to avoid the situation where cracks appear in the casting due to excessive cooling, achieve a gradual cooling effect, and effectively improve the cooling efficiency while ensuring the molding quality of the casting.

[0046] Through the arrangement of the above structure, the recycled aluminum metal is cut to a suitable size and cleaned, and then put into the hot melt tank 2 from the feed pipe 21, and then the closing cylinder 72 pushes the closing plate 71 downward to seal the closing groove 7 and achieve the sealing of the hot melt tank 2. At this time, the aluminum metal in the hot melt tank 2 is hot-melted through the heating chamber 25, and the driving motor 24 is turned on at the same time, so that it cooperates with the pulley group 231 to drive the driving rollers 23 on both sides to rotate, and uses the friction effect to drive the hot melt tank 2 to rotate, so that the aluminum metal inside the hot melt tank 2 rolls, and then is evenly contacted with the heat transferred to the hot melt tank 2, effectively improving the hot melting effect.

[0047] Reference Figure 1 , Figure 2 and Figure 4The casting assembly includes a blanking ring 3, which is rotatably connected to the middle outer wall of the hot melt tank 2, and the rotating shafts of the two sets of driving rollers 23 pass through the side walls of the blanking ring 3 and are rotatably connected thereto. The outer wall of the hot melt tank 2 located in the blanking ring 3 is provided with drip holes 31 at equal intervals. A guide pipe 32 is fixedly connected to the bottom end of the blanking ring 3, and an upper mold 33 is fixedly connected to the bottom end of the guide pipe 32. A guide groove 331 is provided in the upper mold 33, and the guide groove 331 is communicated with the inner cavity of the guide pipe 32, and a quantitative valve is arranged in the guide pipe 32. The quantitative valve belongs to the existing mature technology, and the specific principle is not repeated here. A clamping cylinder 34 is fixedly connected to the equipment frame 1, and a lower mold 35 is fixedly connected to the top of the clamping cylinder 34. A guide rod 36 is fixedly connected to the equipment frame 1, and the top end of the guide rod 36 is fixedly connected to the bottom of the upper mold 33, and the lower mold 35 is slidably sleeved on the guide rod 36.

[0048] Through the arrangement of the above structure, the molten metal liquid will enter the blanking ring 3 along the dripping hole 31. At this time, the mold closing cylinder 34 pushes the lower mold 35 upward, so that the lower mold 35 and the upper mold 33 are fitted together. At this time, the metering valve is opened to allow a certain amount of metal liquid to enter the cavity formed by the lower mold 35 and the upper mold 33 along the guide pipe 32 and the guide groove 331 to form an aluminum profile embryo, thereby completing the remanufacturing of recycled aluminum metal materials and improving energy saving effects.

[0049] Reference Figure 1 , Figure 2 and Figure 4 The bubble discharge mechanism includes an oscillation groove 4, which is provided in the upper mold 33, and two groups of oscillation grooves 4 are symmetrically arranged along the center of the upper mold 33. An impact rod 41 is slidably connected in the oscillation groove 4, and a first spring 42 is fixedly connected between the outer wall of the impact rod 41 and the oscillation groove 4.

Second magnetic plates 431 are arranged at equal intervals on the outer wall of the hot melt tank 2, and the second magnetic plates 431 and the first magnetic plates 43 are magnetically attracted to each other; a first air groove 411 is provided inside the impact rod 41, and the input end of the first air groove 411 is connected to the bottom of the inner cavity of the oscillation groove 4. The side wall of the first air groove 411 is fixed and connected to an exhaust pipe 412. The other end of the exhaust pipe 412 is connected to the top of the inner cavity of the hot melt tank 2, and a one-way valve is arranged in the exhaust pipe 412. The first air grooves 411 of the impact rods 41 on both sides are connected through the first U-shaped tube 413.

[0050] It should be noted that the one-way valve in the exhaust pipe 412 can only allow the gas in the hot melt tank 2 to enter the oscillation tank 4 along the exhaust pipe 412 .

[0051] By setting the above structure, the impact rod 41 is lifted upward by utilizing the attraction between the first magnetic plate 43 and the second magnetic plate 431, so that the first spring 42 is in a stretched state. When the impact rod 41 is pulled upward, a suction effect will be generated at the bottom of the oscillation groove 4, thereby opening the one-way valve in the exhaust pipe 412, so that the gas in the inner cavity of the hot melt tank 2 is sucked into the oscillation groove 4, so that during the continuous rotation of the hot melt tank 2, the gas pressure in the hot melt tank 2 will be reduced, so that the bubbles in the molten metal in the hot melt tank 2 are quickly discharged upward, effectively improving the casting quality of the molten metal; when the first magnetic plate 43 and the second magnetic plate 431 are separated from the repulsive area, under the rebound action of the first spring 42, the impact rod 41 will be quickly reset, thereby impacting the bottom of the oscillation groove 4, so that the upper mold 33 is vibrated as a whole, and acts on the molten metal in the casting cavity, further vibrating and discharging the bubbles in the molten metal, effectively reducing the possibility of bubble defects in the aluminum profile casting, and improving the casting quality of the aluminum profile.

[0052] Reference Figure 2 , Figure 3 , Figure 8 and Fig. 9 The cooling mechanism includes a cooling box 5, which is fixed at the bottom of the lower mold 35, and two groups of cooling boxes 5 are symmetrically arranged along the center of the lower mold 35.

A one-way valve is provided; a pressure relief pipe 54 is slidably connected in the cooling box 5, the top end of the pressure relief pipe 54 extends through to the top of the lower mold 35, the bottom end of the pressure relief pipe 54 extends through to the bottom of the cooling box 5, and a second spring 541 is fixedly connected between the bottom end of the pressure relief pipe 54 and the bottom of the cooling box 5, a pressure relief groove 542 is provided at the bottom end of the pressure relief pipe 54, the input end of the pressure relief pipe 54 is connected to the inner cavity of the cooling box 5, and the height of the pressure relief pipe 54 extending from the top of the lower mold 35 is greater than the distance from the input end of the pressure relief groove 542 to the bottom of the inner cavity of the cooling box 5.

[0053] It should be noted that the one-way valve in the gas charging pipe 53 can only allow the gas in the oscillation tank 4 to enter the cooling box 5 along the gas charging pipe 53 .

[0054] Through the arrangement of the above structure, after the upper mold 33 and the lower mold 35 are fitted together, the upper mold 33 will push the pressure relief pipe 54 to move downward, so that the input end of the pressure relief groove 542 moves out of the cooling box 5, completing the exhaust blocking. When the impact rod 41 moves down and resets, the gas sucked into the oscillation groove 4 will be squeezed, thereby opening the one-way valve in the inflation pipe 53, allowing the gas to enter the cooling box 5 along the inflation pipe 53. At this time, the cooling box 5 is in a sealed state. After repeated reciprocating inflation, the air pressure in the cavity of the cooling box 5 will increase, thereby pushing the piston plate 52 to move upward, thereby squeezing the coolant in the cooling box 5 into the cooling groove 51, thereby conducting cooling through the cooling groove 51 cavity in the early stage of casting, and after the aluminum profile casting is initially formed, conducting cooling of the coolant is realized, thereby avoiding the situation where cracks appear in the casting due to excessive cooling, achieving a gradual cooling effect, and effectively improving the cooling efficiency while ensuring the molding quality of the casting.

[0055] Reference Figure 2 , Figure 6-Figure 8 , wherein a pneumatic box 6 is fixedly connected to the upper part of the side wall of the equipment frame 1, a driven shaft 61 is rotatably connected in the cavity of the positioning shaft 22, one end of the driven shaft 61 extends through the pneumatic box 6 and is fixedly connected to a pneumatic impeller 611, and an exhaust hole 612 is opened on the top of the pneumatic box 6, mounting balls 62 are fixed at equal intervals on the positioning shaft 22, the driven shaft 61 passes through the center of the mounting balls 62, and a stirring paddle 621 is rotatably connected to the bottom of the mounting balls 62, and the top of the rotating shaft of the stirring paddle 621 is connected to the driven shaft 611.

[0056] By setting the above structure, after the casting is completed, the mold closing cylinder 34 drives the lower mold 35 to move downward. At this time, the upper mold 33 will release the squeezing effect on the pressure relief pipe 54. Under the rebound effect of the second spring 541, the pressure relief pipe 54 will move up and reset, so that the input end of the pressure relief groove 542 enters the cooling box 5. At this time, the high-pressure gas in the cooling box 5 will enter the exhaust box 63 along the pressure relief groove 542, and cooperate with the gravity of the coolant to move the piston plate 52 downward and reset, thereby ensuring the cooling effect during the next casting; and the high-pressure gas entering the exhaust box 63 will be transported to the pneumatic box 6 along the exhaust pipe 632, thereby driving the pneumatic impeller 611 to rotate, and then driving the driven shaft 61 to rotate. At this time, in conjunction with the transmission relationship of the bevel gear set 622, the stirring paddle 621 will rotate, thereby improving the mixing effect of the molten metal in the hot melt tank 2, and further accelerating the discharge of bubbles inside it, effectively ensuring the casting quality of the aluminum profile.

[0057] Reference Figure 1-Figure 9 In the present invention, when in use, the recycled aluminum metal is cut to a suitable size and cleaned before being put into the hot melt tank 2 from the feed pipe 21, and then the closing cylinder 72 pushes the closing plate 71 downward to seal the closing groove 7 and achieve the sealing of the hot melt tank 2. At this time, the aluminum metal in the hot melt tank 2 is hot-melted by the heating bin 25, and the driving motor 24 is turned on at the same time, so that it cooperates with the pulley group 231 to drive the driving rollers 23 on both sides to rotate, and the friction effect is used to drive the hot melt tank 2 to rotate, so that the aluminum metal inside the hot melt tank 2 rolls, and then is evenly contacted with the heat transferred to the hot melt tank 2, effectively improving the hot melting effect. The molten metal liquid will flow into the blanking ring 3 along the dripping hole 31. At this time, the clamping cylinder 34 pushes the lower mold 35 upward, so that the lower mold 35 and the upper mold 33 are fitted together. At this time, the metering valve is opened to allow a certain amount of metal liquid to flow into the cavity formed by the lower mold 35 and the upper mold 33 along the guide pipe 32 and the guide groove 331 to form an aluminum profile embryo.

[0058] When the hot melt tank 2 rotates, the attraction between the first magnetic plate 43 and the second magnetic plate 431 will cause the impact rod 41 to be lifted upward, so that the first spring 42 is in a stretched state, and when the impact rod 41 is pulled upward, a suction effect will be generated at the bottom of the oscillation groove 4, thereby opening the one-way valve in the exhaust pipe 412, so that the gas in the inner cavity of the hot melt tank 2 is sucked into the oscillation groove 4, so that during the continuous rotation of the hot melt tank 2, the gas pressure in the hot melt tank 2 will be reduced, so that the bubbles in the molten metal in the hot melt tank 2 are quickly discharged upward, effectively improving the casting quality of the molten metal; when the first magnetic plate 43 and the second magnetic plate 431 are separated from the repulsive area, under the rebound action of the first spring 42, the impact rod 41 will be quickly reset, thereby hitting the bottom of the oscillation groove 4, so that the upper mold 33 is vibrated as a whole, and acts on the molten metal in the casting cavity, further vibrating and discharging the bubbles in the molten metal, effectively reducing the possibility of bubble defects in the aluminum profile casting, and improving the casting quality of the aluminum profile. After the upper mold 33 and the lower mold 35 are fitted together, the upper mold 33 will push the pressure relief pipe 54 to move downward, so that the input end of the pressure relief groove 542 moves out of the cooling box 5, completing the exhaust sealing. When the impact rod 41 moves down and resets, the gas sucked into the oscillation groove 4 will be squeezed, thereby opening the one-way valve in the inflation pipe 53, allowing the gas to enter the cooling box 5 along the inflation pipe 53. At this time, the cooling box 5 is in a sealed state. After repeated reciprocating inflation, the air pressure in the cavity of the cooling box 5 will increase, thereby pushing the piston plate 52 to move upward, thereby squeezing the coolant in the cooling box 5 into the cooling groove 51, so that in the early stage of casting, the cooling is conducted through the cavity of the cooling groove 51. After the aluminum profile casting is initially formed, the conduction cooling of the coolant is realized, so as to avoid the situation where cracks appear in the casting due to excessive cooling, achieve a gradual cooling effect, and effectively improve the cooling efficiency while ensuring the molding quality of the casting.

[0059] After the casting is completed, the mold closing cylinder 34 drives the lower mold 35 to move downward. At this time, the upper mold 33 will release the squeezing effect on the pressure relief pipe 54. Under the rebound effect of the second spring 541, the pressure relief pipe 54 will move up and reset, so that the input end of the pressure relief groove 542 enters the cooling box 5. At this time, the high-pressure gas in the cooling box 5 will enter the exhaust box 63 along the pressure relief groove 542, and cooperate with the gravity of the coolant to move the piston plate 52 downward and reset, thereby ensuring the cooling effect during the next casting; and the high-pressure gas entering the exhaust box 63 will be transported along the exhaust pipe 632 To the pneumatic box 6, thereby driving the pneumatic impeller 611 to rotate, and then driving the driven shaft 61 to rotate. At this time, in conjunction with the transmission relationship of the bevel gear set 622, the stirring paddle 621 will rotate, thereby improving the mixing effect of the molten metal in the hot melt tank 2, and further accelerating the discharge of bubbles inside it, effectively ensuring the casting quality of the aluminum profile, and finally driving the low-temperature gas after the pneumatic impeller 611 rotates will be discharged along the exhaust hole 612, completing the air pressure regulation in the pneumatic box 6, ensuring that the pneumatic impeller 611 can continue to rotate, and improving the stirring effect.
