Description

Technical Field

[0001] This invention relates to the field of aluminum rod casting equipment, and more particularly to a casting apparatus and casting process for recycled aluminum. Background Technology

[0002] Aluminum is a silvery-white, lightweight metal with ductility. It is commonly produced in rod, sheet, foil, powder, strip, and wire forms. In humid air, it forms an oxide film that prevents corrosion. Recycled aluminum is an aluminum alloy or metal obtained by remelting and refining scrap aluminum, aluminum alloys, or aluminum-containing waste. It is an important source of metallic aluminum. Casting is a common method of aluminum forming, where molten aluminum is poured into a mold and cooled to form the desired shape. However, due to practical needs, single-specification aluminum rods require a cutting process, and different molds are needed to produce rods of different specifications, making the operation inconvenient. Furthermore, to prevent splashing during casting, the molten aluminum is usually slowly introduced into the mold. During this process, some of the molten aluminum may solidify first, leading to delamination and cracking of the formed aluminum rod. Therefore, we propose a casting device and process for recycled aluminum to solve the aforementioned problems. Summary of the Invention

[0005] Preferably, a support frame is fixedly connected to the upper outer periphery of the fixed cylinder, and a guide cylinder is fixedly connected to the top of the support frame. The bottom of the guide cylinder is directly opposite the inner center of the receiving plate. A receiving plate is installed on the inner top of the fixed cylinder. The receiving plate has evenly distributed upper through holes on the outer side of the middle part. A limiting port is opened at the bottom of the receiving plate. A rotating plate is rotatably connected inside the limiting port. The rotating plate has evenly distributed casting holes and lower through holes on the outer side of the middle part.

[0006] Preferably, the inner upper and lower parts of the rotating frame are provided with toothed grooves, and a connecting gear is meshed with one side of each toothed groove. The side of each connecting gear away from toothed grooves is meshed with toothed grooves, and toothed grooves are provided on the upper and lower parts of the outer periphery of the mold cylinder.

[0007] Preferably, each of the mold cylinders has a sliding core slidably connected to its inner side, a threaded rod fixedly connected to the bottom of the sliding core, a threaded sleeve threadedly connected to the lower outer periphery of the threaded rod, the threaded sleeve being rotatably connected to one end of the bracket, the brackets being installed on the lower inner side of the fixed cylinder, and a driven gear fixedly connected to the middle outer periphery of each threaded sleeve.

[0008] Preferably, each of the fixed disks has a fixed ring fixedly connected to its opposite end, and each fixed ring has a fixed rod fixedly connected to its opposite end, which is away from the fixed disk. Each fixed rod has a connecting gear rotatably connected to its opposite end, which is away from the fixed ring. The connecting gears are all located between the rotating frame and the mold cylinder.

[0009] Preferably, each threaded rod has a counterweight fixedly connected to its bottom end, the bottom end of each threaded rod penetrates the base plate, each threaded rod is slidably connected to another threaded rod, the base plate is installed on the lower side of the fixed frame, and the counterweights are all located at the bottom of the base plate.

[0010] Preferably, the lower through holes and the casting holes are alternately distributed, the lower through holes and the upper through holes have the same diameter, the bottom of the rotating plate is fixedly connected to the top of the drive end of the geared motor, and the geared motor is mounted on the top of the upper fixed plate.

[0011] Preferably, the mold cylinders are all located inside the rotating frame, and the upper and lower parts of the outer periphery of the mold cylinders are rotatably connected to the outer side of the middle part of the fixed plate. The fixed plate is installed in the upper and lower parts of the fixed cylinder.

[0012] Preferably, the driven gears are all meshed on the outer periphery of the gear disk, the gear disk is fixedly connected to the bottom drive end of the servo motor, and the servo motor is mounted on the bottom end of the lower fixed disk.

[0013] Preferably, a casting process for recycled aluminum includes the following casting steps:

[0014] S1. The molten aluminum liquid is introduced into the receiving plate through the guide tube. The aluminum liquid is further introduced into the casting cylinder through the upper through hole at the bottom of the receiving plate and the casting hole on the rotating plate. During this process, the servo motor drives the gear plate to rotate, which in turn drives the driven gears on the outer periphery to rotate. The driven gears drive the threaded sleeve to rotate synchronously. During this process, under the action of inertia, when the threaded sleeve rotates, it will use friction to drive the threaded rod to rotate synchronously. At the same time, the counterweight block makes the rotation speed between the threaded sleeve and the threaded rod different, so that the threaded rod drives the top sliding core to rise and fall inside the casting cylinder while rotating. By controlling the degree of rising and falling of the sliding core, the length of the aluminum rod is adjusted.

[0015] S2. During the aluminum rod manufacturing process, when the sliding core moves downward from the top, a low-pressure area is formed in the upper part of the mold cylinder. The molten aluminum is quickly drawn from the receiving plate into the mold cylinder through the upper through hole and the casting hole. At the same time, after the molten aluminum solidifies, the stepper motor drives the connected transmission gear to rotate. The outer meshing gear ring drives the other transmission gears to rotate. The transmission gears drive the inner meshing rotating frames to rotate. When the rotating frames rotate, the electromagnets installed on the rotating frames heat the inner mold cylinder, thus preheating the mold cylinder.

[0016] S3. During the rotation of the rotating frame, the connecting gear will be driven to rotate. The connecting gear will drive the mold cylinder to rotate through the meshing tooth grooves. The rotation of the mold cylinder will cause the aluminum liquid to be directly distributed inside the mold cylinder as it enters the mold cylinder, so that the aluminum liquid directly fills the internal space of the mold cylinder.

[0017] S4. After the aluminum rod has cooled, the geared motor is started, which drives the rotating plate to deflect so that the lower through hole on the rotating plate is aligned with the upper through hole. Then, the servo motor is started to rotate in the opposite direction, which drives the threaded rod and the sliding core to rise. The sliding core pushes the solidified aluminum rod upward, and the aluminum rod will be discharged through the lower through hole and the upper through hole, realizing automatic demolding and automatic material discharge.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. During the casting of aluminum bars, a servo motor drives a geared disc to rotate, which in turn drives various driven gears on the outer periphery to rotate. These driven gears then drive the threaded sleeve to rotate synchronously. During this process, due to inertia, the rotation of the threaded sleeve utilizes friction to drive the threaded rod to rotate synchronously. Simultaneously, the counterweight creates a difference in rotation speed between the threaded sleeve and the threaded rod, allowing the threaded rod to move the top sliding core up and down inside the mold cylinder while rotating. This allows the length of the aluminum bars to be adjusted by controlling the degree of lifting and lowering of the sliding core, facilitating the production of aluminum bars of different specifications as needed.

[0020] 2. During the aluminum rod manufacturing process, when the sliding core moves downward from the top, a low-pressure area is formed in the upper part of the mold cylinder. This allows the molten aluminum to be quickly drawn from the receiving plate into the mold cylinder through the upper through hole and the casting hole. This avoids the situation where gas enters simultaneously and generates bubbles when the molten aluminum is poured in directly, which would affect the quality of the formed aluminum rod. At the same time, direct extraction can effectively increase the entry speed of the molten aluminum and reduce the possibility of accidental solidification of the molten aluminum during the process, which is beneficial to practical use.

[0021] 3. After the molten aluminum solidifies, the stepper motor drives the connected transmission gears to rotate. The outer meshing gear ring drives the other transmission gears to rotate, which in turn drives the inner meshing rotating frames to rotate. When the rotating frames rotate, the electromagnets installed on the frames heat the inner casting cylinder, thus preheating the casting cylinder. This prevents the casting cylinder from becoming too cold, which could cause the molten aluminum to solidify directly upon initial contact, leading to cracking and delamination of the aluminum rod. This is beneficial for practical use.

[0022] 4. During the rotation of the rotating frame, the connecting gear will be driven to rotate. The connecting gear can drive the mold cylinder to rotate through the meshing tooth grooves. The rotation of the mold cylinder allows the molten aluminum to be directly distributed inside the mold cylinder as it enters, so that the molten aluminum can directly fill the internal space of the mold cylinder and avoid the existence of gaps that are not filled. At the same time, the opposite rotation of the mold cylinder and the rotating frame can directly accelerate the heating rate of the mold cylinder by the electromagnet, which is beneficial to the aluminum rod casting process.

[0023] 5. After the aluminum rod has cooled, the geared motor can be started, which drives the rotating plate to deflect so that the lower through hole on the rotating plate aligns with the upper through hole. Then, the servo motor is started to rotate in the opposite direction, which drives the threaded rod and the sliding core to rise. The sliding core pushes the solidified aluminum rod upward, and the aluminum rod will be discharged through the lower and upper through holes, realizing automatic demolding and automatic material discharge, which is beneficial to the aluminum rod production. At the same time, when the sliding core rotates, the aluminum rod and the sliding core can be demolded quickly without sticking, making it more convenient to remove the aluminum rod.

[0033] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0034] like Figures 1-8 The apparatus shown is a casting device for recycled aluminum, including an aluminum rod casting cylinder 1. The aluminum rod casting cylinder 1 includes a fixed cylinder 101, with an inner liner 112 installed in the center of the fixed cylinder 101. A rotating frame 128 is evenly distributed inside the inner liner 112. The upper and lower parts of the outer periphery of the rotating frame 128 are rotatably connected to the inner side of a fixed disk 119. The fixed disk 119 is fixedly connected to the upper and lower parts of the inner liner 112. Electromagnets 122 are evenly distributed on the center of the outer periphery of the rotating frame 128. A toothed groove 121 is formed on the upper and lower parts of the outer periphery of the rotating frame 128. A transmission gear 123 is meshed on one side of each toothed groove 121. The transmission gears 123 are installed on the upper and lower parts of the outer periphery of the inner liner 112. All 3 are rotatably connected to the inner liner 112. A stepper motor is connected to a lower transmission gear 123. The stepper motor is installed on the lower part of the outer periphery of the inner liner 112. The side of the transmission gear 123 away from the tooth groove 121 is meshed with the inner side of the tooth ring 113. The tooth ring 113 is rotatably connected to the upper and lower sides of the middle part of the fixed cylinder 101. A fixed ring 124 is fixedly connected to the end of the fixed disk 119 away from the fixed disk 119. A uniformly distributed fixed rod 125 is fixedly connected to the end of the fixed ring 124 away from the fixed disk 119. A connecting gear 116 is rotatably connected to the outer periphery of the end of the fixed rod 125 away from the fixed ring 124. The connecting gear 116 is set between the rotating frame 128 and the casting cylinder 129.

[0035] Furthermore, in specific implementation, during the aluminum rod manufacturing process, when the sliding core 127 moves downwards from the top, a low-pressure area is formed in the upper part of the mold cylinder 129. This allows the molten aluminum to be quickly drawn from the receiving plate 102 into the mold cylinder 129 through the upper through hole 103 and the casting hole 118, avoiding the situation where gas enters simultaneously and generates bubbles when the molten aluminum is poured in directly, which would affect the quality of the formed aluminum rod. At the same time, direct extraction can effectively increase the entry speed of the molten aluminum, reducing the possibility of accidental solidification of the molten aluminum during the process, which is beneficial for practical use. Meanwhile, during the rotation of the rotating frame 128... During operation, the connecting gear 116 will rotate. The connecting gear 116 can drive the mold cylinder 129 to rotate through the meshing tooth groove 130. The rotation of the mold cylinder 129 allows the molten aluminum to be directly distributed inside the mold cylinder 129 as it enters, so that the molten aluminum can directly fill the internal space of the mold cylinder 129 and avoid any gaps. At the same time, the opposite rotation of the mold cylinder 129 and the rotating frame 128 can directly accelerate the heating rate of the mold cylinder 129 by the electromagnet 122, which is beneficial to practical use.

[0036] A support frame 105 is fixedly connected to the upper outer periphery of the fixed cylinder 101. A guide cylinder 104 is fixedly connected to the top of the support frame 105. The guide cylinder 104 is positioned between two upper through holes 103, with its bottom facing the inner center of the receiving plate 102. The receiving plate 102 is installed on the inner top of the fixed cylinder 101. The receiving plate 102 has evenly distributed upper through holes 103 on its outer center. A limit port 117 is opened at the bottom of the receiving plate 102. A rotating plate 133 is rotatably connected inside the limit port 117. The rotating plate 133 has evenly distributed casting holes 118 and lower through holes 115 on its outer center. The lower through holes 115 and casting holes 118 are alternately distributed. The diameters of the lower through holes 115 and upper through holes 103 are the same. The bottom of the rotating plate 133 is fixedly connected to the top of the drive end of the reduction motor 120. The reduction motor 120 is mounted on the top of the upper fixed plate 111.

[0037] Furthermore, in specific implementation, after the aluminum rod has cooled, the geared motor 120 can be started, which drives the rotating plate 133 to deflect, so that the lower through hole 115 on the rotating plate 133 can be aligned with the upper through hole 103. Then, the servo motor 126 is started to rotate in the opposite direction, which drives the threaded rod 109 and the sliding core 127 to rise. The sliding core 127 can push the solidified aluminum rod upward, and the aluminum rod will be discharged through the lower through hole 115 and the upper through hole 103, realizing automatic demolding and automatic material discharge, which is beneficial to the aluminum rod production work. At the same time, when the sliding core 127 rotates, the aluminum rod and the sliding core 127 can be demolded quickly without sticking, making it more convenient to remove the aluminum rod.

[0038] The inner side of the rotating frame 128 is provided with toothed groove 121 on both the upper and lower parts. A connecting gear 116 is meshed with one side of the toothed groove 121. A toothed groove 130 is meshed with the side of the connecting gear 116 away from the toothed groove 121. The toothed groove 130 is provided on the upper and lower parts of the outer periphery of the mold cylinder 129. The mold cylinder 129 is provided on the inner side of the rotating frame 128. The upper and lower parts of the outer periphery of the mold cylinder 129 are rotatably connected to the outer side of the middle part of the fixed plate 111. The fixed plate 111 is installed in the upper and lower parts of the fixed cylinder 101.

[0039] Furthermore, in specific implementation, after the aluminum liquid solidifies, the stepper motor can drive the connected transmission gear 123 to rotate. The outer meshing gear ring 113 can drive the other transmission gears 123 to rotate. The transmission gears 123 can drive the inner meshing rotating frames 128 to rotate. When the rotating frames 128 rotate, the electromagnets 122 installed on the rotating frames 128 can heat the inner casting cylinder 129, thereby preheating the casting cylinder 129. This prevents the casting cylinder 129 from being too cold, which would cause the aluminum liquid in initial contact to solidify directly, resulting in cracking and delamination of the aluminum rod, which is beneficial for practical use.

[0040] Among them, the inner side of the mold cylinder 129 is slidably connected to the sliding core 127, the bottom of the sliding core 127 is fixedly connected to the threaded rod 109, the lower part of the outer periphery of the threaded rod 109 is threadedly connected to the threaded sleeve 132, the threaded sleeve 132 is rotatably connected to one end of the bracket 114, the bracket 114 is installed in the lower part of the inner side of the fixed cylinder 101, the middle part of the outer periphery of the threaded sleeve 132 is fixedly connected to the driven gear 131, the driven gear 131 is meshed with the outer periphery of the gear disk 110, the gear disk 110 is fixedly connected to the bottom drive end of the servo motor 126, the servo motor 126 is installed at the bottom end of the lower fixed disk 119, the bottom end of the threaded rod 109 is fixedly connected to the counterweight 108, the bottom end of the threaded rod 109 passes through the base plate 106, the threaded rod 109 is slidably connected to the threaded rod 109, the base plate 106 is installed in the lower side of the fixed frame 107, and the counterweight 108 is set in the lower part of the base plate 106;

[0041] Furthermore, in practical implementation, the molten aluminum can be guided into the receiving plate 102 through the guide tube 104. The molten aluminum can then be further guided into the casting cylinder 129 through the upper through hole 103 at the bottom of the receiving plate 102 and the casting hole 118 on the rotating plate 133. After the molten aluminum cools and solidifies, it will form the required standard aluminum rod. During this process, the servo motor 126 can drive the gear disk 110 to rotate, which in turn drives the various driven gears 131 meshing on the outer periphery to rotate. The threaded sleeve 132 rotates synchronously. During this process, under the action of inertia, when the threaded sleeve 132 rotates, it will use friction to drive the threaded rod 109 to rotate synchronously. At the same time, the counterweight block 108 can make the rotation speed between the threaded sleeve 132 and the threaded rod 109 different, so that the threaded rod 109 can drive the top sliding core 127 to rise and fall inside the mold cylinder 129 while rotating. This allows people to adjust the length of the aluminum rod by controlling the degree of rise and fall of the sliding core 127, making it convenient to make aluminum rods of different specifications as needed.

[0042] One type of recycled aluminum casting process includes the following casting steps:

[0043] S1. Molten aluminum liquid is introduced into the receiving plate 102 through the guide tube 104. The aluminum liquid is further introduced into the casting mold cylinder 129 through the upper through hole 103 at the bottom of the receiving plate 102 and the casting hole 118 on the rotating plate 133. During this process, the servo motor 126 drives the gear plate 110 to rotate. The gear plate 110 drives the driven gears 131 on the outer periphery to rotate. The driven gears 131 drive the threaded sleeve 132 to rotate synchronously. During this process, under the action of inertia, when the threaded sleeve 132 rotates, it will drive the threaded rod 109 to rotate synchronously using friction. At the same time, the counterweight 108 makes the rotation speed between the threaded sleeve 132 and the threaded rod 109 different. As the threaded rod 109 rotates, it drives the top sliding core 127 to rise and fall inside the casting mold cylinder 129. By controlling the degree of rising and falling of the sliding core 127, the length of the aluminum rod is adjusted.

[0044] S2. During the aluminum rod manufacturing process, when the sliding core 127 moves downward from the top, a low-pressure area is formed in the upper part of the casting cylinder 129. The molten aluminum is quickly drawn from the receiving plate 102 into the casting cylinder 129 through the upper through hole 103 and the casting hole 118. At the same time, after the molten aluminum solidifies, the stepper motor drives the connected transmission gear 123 to rotate. The outer meshing gear ring 113 drives the other transmission gears 123 to rotate. The transmission gears 123 drive the inner meshing rotating frames 128 to rotate. When the rotating frames 128 rotate, the electromagnets 122 installed on the rotating frames 128 heat the inner casting cylinder 129, thereby preheating the casting cylinder 129.

[0045] S3. During the rotation of the rotating frame 128, the connecting gear 116 will be driven to rotate. The connecting gear 116 will drive the mold cylinder 129 to rotate through the meshing tooth groove 130. The rotation of the mold cylinder 129 will cause the aluminum liquid to be directly distributed inside the mold cylinder 129 while entering the mold cylinder 129, so that the aluminum liquid directly fills the internal space of the mold cylinder 129.

[0046] S4. After the aluminum rod has cooled, the geared motor 120 is started, which drives the rotating plate 133 to deflect so that the lower through hole 115 on the rotating plate 133 is aligned with the upper through hole 103. Then, the servo motor 126 is started to rotate in the opposite direction, which drives the threaded rod 109 and the sliding core 127 to rise. The sliding core 127 pushes the solidified aluminum rod upward, and the aluminum rod will be discharged through the lower through hole 115 and the upper through hole 103, realizing automatic demolding and automatic material discharge.

[0047] Working principle:

[0048] In practical use, molten aluminum can be guided into the receiving plate 102 through the guide tube 104. The aluminum can then be further guided into the casting cylinder 129 through the upper through hole 103 at the bottom of the receiving plate 102 and the casting hole 118 on the rotating plate 133. After the aluminum cools and solidifies, it forms the required standard aluminum rod. During this process, the servo motor 126 drives the gear disk 110 to rotate, which in turn drives the various driven gears 131 meshing on the outer periphery to rotate. These driven gears 131 then drive the threaded sleeve 132 to rotate synchronously. During this process, under the influence of inertia, the rotation of the threaded sleeve 132 utilizes friction to drive the threaded rod 109 to rotate synchronously. Simultaneously, the counterweight... The counterweight of 108 allows for a difference in rotational speed between the threaded sleeve 132 and the threaded rod 109. This enables the threaded rod 109 to rotate while simultaneously raising and lowering the top sliding core 127 within the mold cylinder 129. This allows for adjustment of the length of the produced aluminum rod by controlling the degree of raising and lowering of the sliding core 127, facilitating the production of aluminum rods of different specifications. Furthermore, during the aluminum rod production process, as the sliding core 127 moves downwards from the top, a low-pressure area is created in the upper part of the mold cylinder 129. This allows molten aluminum to be quickly drawn from the receiving plate 102 into the mold cylinder 129 through the upper through-hole 103 and the casting hole 118, preventing the simultaneous entry of gas and the generation of air bubbles that could affect the quality of the formed aluminum rod when the molten aluminum is poured in directly. Meanwhile, direct extraction effectively increases the entry speed of molten aluminum, reducing the possibility of accidental solidification during the process, which is beneficial for practical use. After the molten aluminum solidifies, a stepper motor drives the connected transmission gears 123 to rotate. The outer meshing gear ring 113 drives the remaining transmission gears 123 to rotate, which in turn drives the inner meshing rotating frames 128 to rotate. When the rotating frames 128 rotate, the electromagnets 122 mounted on them heat the inner casting cylinder 129, thus preheating it. This prevents the casting cylinder 129 from becoming too cold, which could cause the molten aluminum to solidify directly upon initial contact, leading to cracking and delamination of the aluminum rod. This is beneficial for practical applications. In operation, the rotation of the rotating frame 128 drives the connecting gear 116 to rotate. The connecting gear 116, through its meshing tooth grooves 130, drives the casting cylinder 129 to rotate. This rotation of the casting cylinder 129 allows the molten aluminum to be directly distributed inside as it enters, ensuring complete filling of the internal space and preventing any gaps. Simultaneously, the counter-rotation of the casting cylinder 129 and the rotating frame 128 accelerates the heating rate of the casting cylinder 129 by the electromagnet 122, which is beneficial for practical use. After the aluminum rod has cooled, the reduction motor 120 can be activated, which drives the rotating plate 133 to deflect.This aligns the lower through-hole 115 on the rotating plate 133 with the upper through-hole 103. Then, the servo motor 126 is activated to rotate in the opposite direction, causing the threaded rod 109 and the sliding core 127 to rise. The sliding core 127 pushes the solidified aluminum rod upwards, and the aluminum rod is discharged through the lower through-hole 115 and the upper through-hole 103, achieving automatic demolding and automatic material discharge, which is beneficial for aluminum rod production. Simultaneously, when the sliding core 127 rotates, it allows for rapid demolding of the aluminum rod without sticking, making the removal of the aluminum rod more convenient.

10. A casting process for recycled aluminum, applied to a casting apparatus for recycled aluminum according to any one of claims 1-9, characterized in that: The following pouring steps are included: S1. The molten aluminum liquid is introduced into the receiving plate (102) through the guide tube (104). The aluminum liquid is further introduced into the casting mold cylinder (129) through the upper through hole (103) at the bottom of the receiving plate (102) and the casting hole (118) on the rotating plate (133). During this process, the gear plate (110) is driven to rotate by the servo motor (126). The gear plate (110) drives the driven gears (131) on the outer periphery to rotate. The driven gears (131) drive the threaded sleeve (132) to rotate. The threaded sleeve (132) rotates synchronously under the action of inertia. When the threaded sleeve (132) rotates, it will use friction to drive the threaded rod (109) to rotate synchronously. At the same time, the counterweight (108) makes the rotation speed between the threaded sleeve (132) and the threaded rod (109) different. This causes the threaded rod (109) to drive the top sliding core (127) to rise and fall inside the mold cylinder (129) while rotating. By controlling the degree of rise and fall of the sliding core (127), the length of the aluminum rod is adjusted. S2. During the aluminum rod manufacturing process, when the sliding core (127) moves downward from the top, a low-pressure area is formed in the upper part of the casting cylinder (129). The aluminum liquid is quickly drawn from the receiving plate (102) into the casting cylinder (129) through the upper through hole (103) and the casting hole (118). At the same time, after the aluminum liquid solidifies, the stepper motor drives the connected transmission gear (123) to rotate. The outer meshing gear ring (113) drives the other transmission gears (123) to rotate. The transmission gears (123) drive the inner meshing rotating frames (128) to rotate. When the rotating frames (128) rotate, the electromagnets (122) installed on the rotating frames (128) heat the inner casting cylinder (129) to achieve preheating of the casting cylinder (129). S3. During the rotation of the rotating frame (128), the connecting gear (116) will be driven to rotate. The connecting gear (116) will drive the mold cylinder (129) to rotate through the meshing tooth groove (130). The rotation of the mold cylinder (129) will cause the aluminum liquid to be directly distributed inside the mold cylinder (129) while entering the mold cylinder (129), so that the aluminum liquid directly fills the internal space of the mold cylinder (129). S4. After the aluminum rod has cooled, the geared motor (120) is started, which drives the rotating plate (133) to deflect so that the lower through hole (115) on the rotating plate (133) is aligned with the upper through hole (103). Then, the servo motor (126) is started to rotate in the opposite direction, which drives the threaded rod (109) and the sliding core (127) to rise. The solidified aluminum rod is pushed upward by the sliding core (127), and the aluminum rod will be discharged through the lower through hole (115) and the upper through hole (103), realizing automatic demolding and automatic material discharge.
