Description

Technical Field

[0001] The invention relates to the technical field of manufacturing eccentric circular arc carbon blocks, and in particular to a molding device used for manufacturing eccentric circular arc carbon blocks. Background Art

[0002] With the development of society, aluminum occupies a pivotal position in modern industry and daily life. Aluminum has many excellent properties such as light weight, high strength, corrosion resistance, good electrical conductivity and thermal conductivity, and aluminum electrolysis is the core process of industrial production of aluminum. It is based on the principle of electrolysis, using alumina as raw material. In a molten state, aluminum ions are reduced to metal aluminum by strong direct current at the cathode to obtain electrons, thereby realizing large-scale production of aluminum. In the process of aluminum electrolysis, anode carbon blocks play an indispensable and key role. As the anode of the electrolytic cell, the anode carbon block not only conducts current to enable the electrolytic reaction to continue, but also participates in chemical reactions and is gradually consumed under high temperature and strong current environments. High-quality anode carbon blocks can ensure the stable operation of the electrolytic cell, reduce the occurrence of anode effect, and reduce energy consumption and production costs. It is of great significance to the efficient and sustainable development of the aluminum industry.

[0003] As a special structure of anode carbon blocks, eccentric arc carbon blocks play a unique role in specific aluminum electrolytic cell designs. The shape of the eccentric arc can optimize the current distribution and the flow characteristics of the electrolyte, which helps to improve the service life of the electrolytic cell and the stability of aluminum production. However, when casting eccentric arc carbon blocks, the demolding process is relatively slow. This is mainly due to its special eccentric arc shape and shrinkage boss structure, which easily generates a large friction force with the inner wall of the mold during demolding. When trying to remove the carbon block from the mold, these forces will hinder the smooth movement of the carbon block, and it is necessary to overcome a large resistance to make the carbon block out of the mold. Moreover, due to its irregular shape, it is difficult to ensure uniform force on all parts during the demolding process, and it is easy to get stuck, which further slows down the demolding speed. This is not conducive to large-scale and efficient industrial production. Summary of the invention

[0025] Reference Figure 1-7The present invention provides a molding device for manufacturing eccentric arc carbon blocks: comprising a bottom plate 1, a first support rod 101 is fixed on the top of the bottom plate 1, the number of the first support rods 101 is multiple, an upper mold 2 is fixedly connected to the top of the multiple first support rods 101, a lifting plate 3 is movably installed between the bottom plate 1 and the upper mold 2, a lower mold 4 is movably installed between the upper mold 2 and the lifting plate 3, a feeding assembly 5 is fixedly installed on the top of the upper mold 2, a first lifting mechanism 6 is installed between the bottom plate 1 and the lifting plate 3, a second lifting mechanism 7 is installed between the lifting plate 3 and the lower mold 4, an eccentric arc carbon block body 8 is placed between the upper mold 2 and the lifting plate 3, a support column 301 is fixedly connected to the top of the lifting plate 3, and the support column There are multiple numbers of 301, and the tops of multiple support columns 301 are fixedly connected with support frames 302, and the support frames 302 are located at the bottom of the mold groove inside the upper mold 2; the first lifting mechanism 6 includes a first screw rod 601, a first slide rod 602, a first ear plate 603, a second ear plate 604 and a connecting rod 605, the first screw rod 601 is movably installed on the top of the base plate 1, the first slide rod 602 is fixedly installed on the top of the base plate 1 and is located on one side of the first screw rod 601, four first ear plates 603 are movably installed on the first screw rod 601 and the first slide rod 602, four second ear plates 604 are fixedly connected to the bottom of the lifting plate 3, and the connecting rod 605 is movably installed between the first ear plate 603 and the second ear plate 604.

[0026] When in use, first, the lower mold 4 and the upper mold 2 are tightly fitted together, and the raw material is injected into the mold groove between the lower mold 4 and the upper mold 2 through the feeding assembly 5 for casting. When the casting is completed and the mold needs to be demolded, the first drive motor 606 is started, and the first drive motor 606 drives the first screw rod 601 to rotate. The first screw rod 601 and the first slide rod 602 are parallel to each other and the first slide rod 602 plays a guiding role. When the first screw rod 601 rotates, the first ear plate 603 produces axial movement on the first screw rod 601 due to the action of the thread, and slides smoothly along the first slide rod 602. The second ear plate 604 is fixed to the bottom of the lifting plate 3, thereby converting the rotational motion of the first screw rod 601 into a linear lifting motion of the lifting plate 3, driving the lifting plate 3 and the lower mold 4 to descend together, so that the eccentric arc carbon block body 8 is separated from the upper mold 2, completing the first-level demolding operation, and then the second lifting mechanism 7 and the support frame 302 cooperate to realize the second-level demolding operation.

[0027] The eccentric arc carbon block body 8 is composed of a carbon block body 801 and a shrinkage boss 802 . The shrinkage boss 802 is located at the top of the shrinkage boss 802 . The carbon block body 801 is cast by the lower mold 4 , and the shrinkage boss 802 is cast by the upper mold 2 .

[0028] During the casting process, the raw materials enter the cavity of the upper mold 2 and the lower mold 4 respectively through the feed assembly 5. The shape of the cavity of the lower mold 4 matches the shape of the carbon block 801 and is used to form the carbon block 801; the cavity of the upper mold 2 is used to form the shrinkage boss 802. Through the closing of the upper and lower molds and the filling and solidification of the raw materials, an eccentric arc carbon block body with a specific shape is finally formed.

[0029] A first driving motor 606 is fixedly mounted on the top of the bottom plate 1 , and one end of the first screw rod 601 is fixedly mounted on the output end of the first driving motor 606 .

[0030] The first drive motor 606 serves as the power source of the first lifting mechanism 6, converts electrical energy into mechanical energy, outputs torque to drive the first screw 601 to rotate, provides power for the lifting and lowering movement of the lifting plate 3 and the lower mold 4, controls their lifting speed and displacement, realizes precise demolding operation, and ensures the stability and reliability of the demolding process.

[0031] The second lifting mechanism 7 includes a third ear plate 701, a second screw rod 702, a belt groove 704 and a driving belt 705. The third ear plate 701 has four fixed connections in sequence to both sides of the outer wall of the lower mold 4 and both sides of the outer wall of the lifting plate 3. The second screw rod 702 has two threads installed inside the two third ear plates 701 on the same side. The belt groove 704 is opened on the bottom outer wall of the second screw rod 702, and the driving belt 705 is fixedly installed between the two belt grooves 704.

[0032] After the first-level demoulding is completed, the third drive motor 703 is started, and the third drive motor 703 drives the second screw rod 702 on one side to rotate. Since the two second screw rods 702 are connected by the belt groove 704 and the driving belt 705, when the second screw rod 702 on one side rotates, with the help of belt transmission, the second screw rod 702 on the other side rotates synchronously, and the threaded cooperation between the second screw rod 702 and the third ear plate 701 causes the third ear plate 701 to produce axial movement on the second screw rod 702, and the third ear plates 701 on both sides of the lower mold 4 move in opposite directions, thereby causing the lower mold 4 to move downward relative to the lifting plate 3. Since the lifting plate 3 is fixedly connected to the support column 301 and the support frame 302, the eccentric arc carbon block body 8 is supported by the support frame 302, thereby realizing the second-level demoulding, and the eccentric arc carbon block body 8 is separated from the lower mold 4.

[0033] A protective cover 706 is fixedly connected to the bottom of the lifting plate 3 , a third drive motor 703 is fixedly installed inside the protective cover 706 , and a bottom end of the second screw rod 702 on one side is fixedly installed at the output end of the third drive motor 703 .

[0034] The protective cover 706 serves to protect the third drive motor 703, preventing dust, impurities, etc. during the casting process from entering the inside of the motor and affecting the normal operation and service life of the motor; the third drive motor 703 serves as the power source of the second lifting mechanism 7, driving the second screw rod 702 to rotate, realizing the precise movement of the lower mold 4 and ensuring the smooth progress of the secondary demolding process.

[0035] The top of the bottom plate 1 is fixedly connected with a second slide bar 607 . There are four second slide bars 607 distributed in a rectangular shape. The second slide bars 607 movably penetrate the lifting plate 3 and the lower mold 4 .

[0036] The second slide bar 607 provides additional guidance and support for the lifting and lowering movement of the lifting plate 3 and the lower mold 4, so that the lifting plate 3 and the lower mold 4 can move more smoothly and accurately under the drive of the first lifting mechanism 6 and the second lifting mechanism 7, reducing shaking and deviation during movement, improving the accuracy and reliability of demolding operations, and preventing damage to the eccentric arc carbon block body 8 due to unstable mold movement.

[0037] The feeding assembly 5 includes a feeding funnel 501, a second support rod 502, a first discharge pipe 503, a second discharge pipe 504 and a feeding channel 505. The feeding funnel 501 is fixedly connected to the top of the upper mold 2. The second support rod 502 has two fixed connections between the upper mold 2 and the feeding funnel 501. The first discharge pipe 503 is fixedly connected to the bottom of the feeding funnel 501. The second discharge pipe 504 is fixedly connected to the output end of the first discharge pipe 503. A feeding channel 505 is opened inside the upper mold 2. The feed channel 505 is connected to the mold groove inside the upper mold 2, and the feed channel 505 is connected to the second discharge pipe 504.

[0038] During casting, the raw material is poured from the feed funnel 501, passes through the first discharge pipe 503 and the second discharge pipe 504 into the feed channel 505, and then flows into the mold grooves of the upper mold 2 and the lower mold 4 respectively through the feed channel 505, so as to achieve uniform filling of the raw material, ensure the molding quality of the eccentric arc carbon block body 8, and make the internal structure of the carbon block uniform and the performance stable.

[0039] Working principle: When manufacturing eccentric arc carbon blocks, first fit the lower mold 4 and the upper mold 2 tightly together, then pour the raw materials through the feed funnel 501, and the raw materials enter the mold grooves of the upper mold 2 and the lower mold 4 respectively through the first discharge pipe 503, the second discharge pipe 504 and the feed channel 505, and the eccentric arc carbon block body 8 is formed through the curing molding and other process processes.

[0040] When the casting is completed and needs to be demolded, the first drive motor 606 is started. The first drive motor 606 drives the first screw rod 601 to rotate, and the first ear plate 603 moves on the first screw rod 601 and the first slide rod 602. The lifting plate 3 and the lower mold 4 are driven to descend together through the connecting rod 605, so that the eccentric arc carbon block body 8 is separated from the upper mold 2, completing the first-level demolding.

[0041] Then start the third drive motor 703, which drives the second screw rod 702 on one side to rotate. With the help of the belt groove 704 and the drive belt 705, the second screw rods 702 on both sides rotate synchronously, the third ear plate 701 moves, and the lower mold 4 moves downward. Since the lifting plate 3 is fixedly connected to the support column 301 and the support frame 302, the eccentric arc carbon block body 8 is supported by the support frame 302, realizing secondary demolding, so that the eccentric arc carbon block body 8 is separated from the lower mold 4.
