Description

Technical Field

[0001] The invention relates to the field of aluminum rod casting equipment, and in particular to a casting device and a casting process for recycled aluminum. Background Art

[0002] Aluminum is a silvery-white light metal with ductility. The products are often made into rods, sheets, foils, powders, strips and wires. It can form an oxide film to prevent metal corrosion in humid air. Recycled aluminum is an aluminum alloy or aluminum metal obtained by remelting and refining scrap aluminum and scrap aluminum alloy materials or aluminum-containing waste. It is an important source of metallic aluminum. Casting is one of the common ways to form aluminum. It is formed by pouring high-temperature molten aluminum into a casting mold and cooling it. However, due to practical needs, a single-specification aluminum rod needs to be cut when used. Different molds are required when making aluminum rods of different specifications, which is inconvenient to operate. At the same time, in order to prevent aluminum liquid from splashing during the casting process, the aluminum liquid is usually slowly introduced into the mold. The aluminum liquid may partially solidify first during this process, resulting in delamination and cracking of the formed aluminum rod. Therefore, we propose a casting device and casting process for recycled aluminum to solve the above-mentioned problems. Summary of the invention

[0006] Preferably, the upper and lower parts of the inner side of the rotating frame are both provided with tooth groove 1, one side of the tooth groove 1 is meshed with a connecting gear, the side of the connecting gear away from tooth groove 1 is meshed with tooth groove 2, and the tooth groove 2 is provided at the upper and lower parts of the outer circumference of the mold cylinder.

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

[0008] Preferably, the ends of the fixed disks away from each other are fixedly connected to fixed rings, the ends of the fixed rings away from the fixed disks are fixedly connected to evenly distributed fixed rods, the outer peripheries of the ends of the fixed rods away from the fixed rings are rotatably connected to connecting gears, and the connecting gears are arranged between the rotating frame and the mold cylinder.

[0009] Preferably, the bottom ends of the threaded rods are fixedly connected to counterweights, the bottom ends of the threaded rods pass through the bottom plate, the threaded rods are slidably connected to the threaded rods, the bottom plate is installed on the lower inner side of the fixed frame, and the counterweights are arranged at the lower part of the bottom plate.

[0010] Preferably, the lower through holes and the casting holes are alternately distributed, the diameters of the lower through holes and the upper through holes are the same, the bottom of the rotating plate is fixedly connected to the top of the reduction motor driving end, and the reduction motor is installed on the top of the upper fixed plate.

[0011] Preferably, the mold cylinder is arranged on the inner side of the rotating frame, the upper and lower parts of the outer circumference of the mold cylinder are rotatably connected to the outer side of the middle part of the fixed plate, and the fixed plate is installed in the upper and lower parts of the fixed cylinder.

[0012] Preferably, the driven gears are meshedly connected to the outer periphery of the toothed disc, the toothed disc is fixedly connected to the bottom driving end of the servo motor, and the servo motor is installed at the bottom end of the lower fixed disc.

[0013] Preferably, a casting process of recycled aluminum comprises the following casting steps: S1. The molten aluminum liquid is introduced into the receiving plate through the guide tube, and the aluminum liquid is further introduced into the mold tube through the upper through hole at the bottom of the receiving plate and the casting hole on the rotating plate. In this process, the toothed disc is driven to rotate by the servo motor, and the driven gears meshing on the outer periphery are driven to rotate, and the threaded sleeve is driven to rotate synchronously by the driven gear. In this process, when the threaded sleeve rotates under the action of inertia, the friction force is used to drive the threaded rod to rotate synchronously. At the same time, the counterweight effect of 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 mold tube while rotating, and the length of the aluminum rod is adjusted by controlling the lifting degree of the sliding core; S2. In the process of making aluminum rods, when the sliding core moves downward from the top, a low-pressure area will be formed in the upper part of the mold barrel, and the aluminum liquid will be quickly drawn from the receiving plate into the mold barrel through the upper through hole and the casting hole. At the same time, after the aluminum liquid solidifies, the transmission gear on one side is driven to rotate by the stepper motor, and the other transmission gears are driven to rotate by the meshing gear ring on the outside, and the meshing rotating racks on the inside are driven to rotate by the transmission gear. When the rotating rack rotates, the inner mold barrel is heated by the electromagnets installed on the rotating rack to realize preheating of the mold barrel; S3. During the rotation of the rotating frame, the connecting gear is driven to rotate, and the connecting gear uses the meshing tooth grooves to drive the mold barrel to rotate. The rotation of the mold barrel allows the aluminum liquid to enter the mold barrel and directly spread inside the mold barrel, so that the aluminum liquid directly fills the internal space of the mold barrel; S4. After the aluminum rod is cooled, people start the reduction motor, which drives the rotating plate to deflect so that the lower through hole and the upper through hole on the rotating plate are aligned. Then, the servo motor is started to rotate in the opposite direction, driving the threaded rod and the sliding core to rise. The solidified aluminum rod is pushed upward by the sliding core, and the aluminum rod is discharged through the lower through hole and the upper through hole, realizing automatic demoulding and automatic discharging.

[0014] Compared with the prior art, the present invention has the following beneficial effects: During the process of casting aluminum rods, the servo motor can drive the gear disc to rotate, and the gear disc can drive the various driven gears meshing on the outer periphery to rotate, and the driven gear can drive the threaded sleeve to rotate synchronously. In this process, under the action of inertia, when the threaded sleeve rotates, the friction force will be used to drive the threaded rod to rotate synchronously. At the same time, the counterweight effect of the counterweight block can make the rotation speed of the threaded sleeve and the threaded rod different, so that the threaded rod can drive the top sliding core to rise and fall inside the mold barrel while rotating, so that people can adjust the length of the aluminum rod by controlling the lifting degree of the sliding core, so that people can make aluminum rods of different specifications as needed.

[0015] In the process of making aluminum rods, when the sliding core moves downward from the top, a low-pressure area will be formed in the upper part of the mold barrel, so that the molten aluminum can be quickly drawn from the receiving tray into the mold barrel through the upper through hole and the casting hole, avoiding the simultaneous entry of gas to produce bubbles when the molten aluminum is directly poured in, which affects the quality of the aluminum rod after molding. 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.

[0016] After the aluminum liquid solidifies, the stepper motor can drive the transmission gear on one side to rotate, and the meshing gear ring on the outside can drive the other transmission gears to rotate, and the transmission gear can drive the meshing turntables on the inside to rotate. When the turntable rotates, the electromagnets installed on the turntable can heat the inner mold cylinder, thereby preheating the mold cylinder and avoiding the direct solidification of the aluminum liquid initially contacted by the mold cylinder due to overcooling, which causes the aluminum rod to crack and delaminate, which is beneficial to practical use.

[0017] During the rotation of the turret, the connecting gear will be driven to rotate, and the meshing teeth of the connecting gear can be used to drive the mold barrel to rotate. The rotation of the mold barrel can make the aluminum liquid directly spread inside the mold barrel while entering the mold barrel, so that the aluminum liquid can directly fill the internal space of the mold barrel to avoid the existence of unfilled gaps. At the same time, the opposite rotation of the mold barrel and the turret can directly accelerate the heating rate of the electromagnet to the mold barrel, which is beneficial to the casting process of the aluminum rod.

[0018] After the aluminum rod is cooled, people can start the reduction motor, which can drive the turn plate to deflect so that the lower through hole on the turn plate can be aligned with the upper through hole. Then start the servo motor to rotate in the opposite direction, which can drive the threaded rod and the sliding core to rise. The solidified aluminum rod can be pushed upward through the sliding core, and the aluminum rod will be discharged through the lower through hole and the upper through hole to achieve automatic demoulding and automatic discharging, which is beneficial to the production of aluminum rods. At the same time, when the sliding core rotates, the aluminum rod and the sliding core can be quickly demoulded without sticking, making it more convenient to take out the aluminum rod.

In this process, the servo motor 126 can drive the toothed disc 110 to rotate, and the toothed disc 110 can drive the various driven gears 131 meshing on the outer periphery to rotate, and the driven gears 131 can The threaded sleeve 132 is driven to rotate synchronously. During this process, under the action of inertia, when the threaded sleeve 132 rotates, the friction force is used to drive the threaded rod 109 to rotate synchronously. At the same time, the counterweight effect of the counterweight block 108 can make the rotation speeds of 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 tube 129 while rotating, so that people can adjust the length of the manufactured aluminum rod by controlling the lifting degree of the sliding core 127, so that people can make aluminum rods of different specifications as needed.

[0026] Among them, a casting process of recycled aluminum includes the following casting steps: S1. The molten aluminum liquid is introduced into the receiving plate 102 through the guide tube 104, and the aluminum liquid is further introduced into the mold tube 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. In this process, the toothed disc 110 is driven to rotate by the servo motor 126, and the peripheral meshing driven gears 131 are driven to rotate by the toothed disc 110, and the threaded sleeve 132 is driven to rotate synchronously by the driven gear 131. In this process, under the action of inertia, when the threaded sleeve 132 rotates, the friction force is used to drive the threaded rod 109 to rotate synchronously. At the same time, the counterweight effect of the counterweight block 108 makes the rotation speeds of the threaded sleeve 132 and the threaded rod 109 different, so that the threaded rod 109 drives the top sliding core 127 to rise and fall in the mold tube 129 while rotating, and the length of the aluminum rod is adjusted by controlling the lifting degree of the sliding core 127; S2. In the process of making aluminum rods, when the sliding core 127 moves downward from the top, a low-pressure area is formed in the upper part of the mold barrel 129, and the aluminum liquid is quickly drawn from the receiving plate 102 into the mold barrel 129 through the upper through hole 103 and the casting hole 118. At the same time, after the aluminum liquid solidifies, the transmission gear 123 on one side is driven to rotate by the stepper motor, and the other transmission gears 123 are driven to rotate by the outer meshing gear ring 113, and the inner meshing rotating racks 128 are driven to rotate by the transmission gear 123. When the rotating rack 128 rotates, the inner mold barrel 129 is heated by the electromagnets 122 installed on the rotating rack 128, so as to preheat the mold barrel 129. S3. During the rotation of the rotating frame 128, the connecting gear 116 is driven to rotate, and the connecting gear 116 uses the meshing tooth groove 130 to drive the mold barrel 129 to rotate. The rotation of the mold barrel 129 allows the aluminum liquid to enter the mold barrel 129 and directly spread inside the mold barrel 129, so that the aluminum liquid directly fills the internal space of the mold barrel 129; S4. After the aluminum rod is cooled, the reduction motor 120 is started, and the rotating plate 133 is driven to deflect by the reduction motor 120, 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, driving the threaded rod 109 and the sliding core 127 to rise, and the solidified aluminum rod is pushed upward by the sliding core 127, and the aluminum rod is discharged through the lower through hole 115 and the upper through hole 103, realizing automatic demoulding and automatic discharging.

[0027] Working principle: In actual use, people can guide the molten aluminum liquid into the receiving plate 102 through the guide tube 104, and can further guide the aluminum liquid into the mold tube 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 that, when the aluminum liquid cools and solidifies, it will form the required standard aluminum rod. In this process, the servo motor 126 can drive the toothed disc 110 to rotate, and the toothed disc 110 can drive the various driven gears 131 meshing on the outer periphery to rotate, and the driven gear 131 can drive the threaded sleeve 132 to rotate synchronously. In 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, and at the same time, the counterweight block The counterweight effect of 108 can make the rotation speeds of 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 barrel 129 while rotating, so that people can adjust the length of the aluminum rod by controlling the degree of rise and fall of the sliding core 127, which is convenient for people to make aluminum rods of different specifications as needed. At the same time, in the process of making aluminum rods, when the sliding core 127 moves from the top to the bottom, a low-pressure area will be formed in the upper part of the mold barrel 129, so that the aluminum liquid can be quickly drawn from the receiving tray 102 into the mold barrel 129 through the upper through hole 103 and the casting hole 118, avoiding the situation where gas enters synchronously to produce bubbles when the aluminum liquid is directly poured, which affects the quality of the aluminum rod after molding. At the same time, direct extraction can effectively increase the speed at which the aluminum liquid enters, reducing the possibility of accidental solidification of the aluminum liquid during the process, which is beneficial to practical use. At the same time, after the aluminum liquid solidifies, the stepper motor can drive the transmission gear 123 on one side to rotate, and the gear ring 113 meshing on the outside can drive the other transmission gears 123 to rotate, and the transmission gear 123 can drive the various rotating racks 128 meshing on the inside to rotate. When the rotating rack 128 rotates, the various electromagnets 122 installed on the rotating rack 128 can heat the inner mold barrel 129, thereby preheating the mold barrel 129 and avoiding overcooling of the mold barrel 129, which causes the aluminum liquid that is initially in contact to directly solidify, resulting in cracking and stratification of the aluminum rod, which is beneficial to practical use. During use, during the rotation of the rotating frame 128, the connecting gear 116 is driven to rotate, and the meshing tooth groove 130 can be used to drive the mold barrel 129 to rotate. The rotation of the mold barrel 129 can make the aluminum liquid directly spread inside the mold barrel 129 while entering the mold barrel 129, so that the aluminum liquid can directly fill the internal space of the mold barrel 129 to avoid the existence of unfilled gaps. At the same time, the opposite rotation of the mold barrel 129 and the rotating frame 128 can directly accelerate the heating rate of the electromagnet 122 to the mold barrel 129, which is beneficial to practical use. After the cooling of the aluminum rod is completed, people can start the reduction motor 120, and the reduction motor 120 can drive the rotating plate 133 to deflect.The lower through hole 115 on the rotating plate 133 can be aligned with the upper through hole 103, and then the servo motor 126 is started to rotate in the opposite direction, which can drive the threaded rod 109 and the sliding core 127 to rise. The solidified aluminum rod can be pushed upward through 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 demoulding and automatic discharging, which is beneficial to the production of aluminum rods. At the same time, when the sliding core 127 rotates, the aluminum rod and the sliding core 127 can be quickly demoulded without adhesion, making it more convenient to take out the aluminum rod.
