Description

Technical Field

[0001] The invention relates to the technical field of metal casting, and in particular to a casting device and a casting method for a GIS conductor. Background Art

[0002] GIS conductor is an electrical device used in high-voltage transmission lines. It has excellent insulation properties and can withstand high voltage and current. There are several main casting methods for GIS conductors, including remelting regeneration, continuous casting, centrifugal casting and arc casting. Among them, the centrifugal casting method uses the centrifugal force generated by rotation to fill the mold with molten metal materials under the action of centrifugal force, and complete solidification and cooling in the mold. This method can produce high-quality castings, but the production cost is relatively high.

[0003] A casting mold is disclosed in the patent with the announcement number CN117960997A. A pouring port is set on one side of the top of the upper mold. When pouring, the worker manually clamps the pouring bucket containing molten metal and pours it towards the pouring port to realize the pouring of the molten metal.

[0004] However, the prior art still has the following defects:

[0005] In the traditional metal casting process, molten metal is usually poured into a casting machine for casting. In this process, it is often necessary to manually clamp a pouring bucket filled with high-temperature molten metal with a clamp and then pour it into the casting equipment.

[0006] When pouring high-temperature molten metal, workers need to manually hold the pouring bucket with clamps and pour it. During the pouring process, the high-temperature molten metal is very hot, which can easily cause safety accidents such as scalding. The long-term lifting operation may cause workers to come into contact with the hot molten metal when they are not paying attention, increasing the risk of scalding and low safety. In addition, the labor intensity is high, and workers need to remain highly vigilant for a long time, constantly lifting and pouring. Because the pouring bucket is heavy, in the long run, it may cause workers to be physically exhausted and even cause health problems;

[0007] Moreover, when pouring, the pouring bucket is clamped by workers manually pressing, which may cause the pouring bucket to fall off due to insufficient clamping force, and the high-temperature molten metal will spill, causing burns. Also, when pouring, the workers have to align the pouring port by themselves, and the pouring position is not fixed, alignment is difficult, and the pouring efficiency is relatively low. Therefore, it is necessary to develop a new type of casting equipment to solve the above problems. Summary of the invention

[0008] In view of the problems of the prior art in pouring molten metal, such as low safety, difficult alignment and low pouring efficiency, a casting device and a casting method for a GIS conductor are proposed.

[0009] The purpose is to place a pouring bucket filled with high-temperature molten metal directly on a pouring component to achieve automatic turning over and pouring of the pouring bucket, thereby improving the safety and efficiency of pouring.

[0010] The technical solution of the present invention is a casting device for GIS conductors, comprising a mounting frame and a casting motor arranged at the bottom of the mounting frame, a protective cover arranged at the top of the mounting frame, an upper mold arranged at the middle of the mounting frame, a lower mold arranged at the bottom of the upper mold, an injection port arranged at the top of the upper mold, a rotating rod arranged at the bottom of the lower mold, a baffle arranged at one side of the top of the protective cover, and a rotating disk arranged at the bottom of the rotating rod, wherein the rotating disk and the casting motor are driven by a belt, and also includes a liquid pouring component;

[0011] The liquid pouring component includes a driving assembly arranged at the bottom of the baffle, a transmission assembly arranged at one side of the driving assembly, and a placement assembly arranged at one side of the driving assembly;

[0012] The driving assembly includes a driving motor arranged on one side of the top of the baffle, a driving tooth arranged on one end of the output shaft of the driving motor, a transmission tooth arranged on one side of the driving tooth, a ball screw arranged in the middle of the transmission tooth, and a support frame arranged on the top of the baffle, and the two ends of the ball screw are respectively rotatably connected to the middle of the support frame and the baffle;

[0013] The pouring component is used to pour molten metal during casting, and the driving component drives the placement component to rotate through the transmission component, so that the molten metal in the placement component is poured from the injection port into the upper mold and the lower mold for casting.

[0014] By adopting the above technical scheme, the automatic pouring of molten metal during centrifugal casting is realized by the provided pouring component. The molten metal flows into the space between the upper mold and the lower mold through the injection port. Driven by the casting motor, the belt drives the rotating disk to rotate, the rotating disk drives the rotating rod to rotate, and the rotating rod drives the upper mold and the lower mold to rotate, so that the molten metal injected into the upper mold and the lower mold fills the internal mold groove under the action of the rotating centrifugal force, and the casting is completed. When the pouring component is working, the driving component drives the transmission component to rotate through the driving component, thereby driving the placement component to rotate, and the pouring of the molten metal during casting is completed. When the driving component is working, the output shaft of the driving motor drives the driving teeth to rotate, the driving teeth drive the transmission teeth to rotate, and the transmission teeth drive the ball screw to rotate. The rotation of the ball screw causes the transmission component to move on the ball screw, and the ball screw is limited at the top of the support frame.

[0015] Furthermore, the transmission assembly includes a ball block arranged on the ball screw, and a transmission rod arranged at the bottom of one side of the ball block, and one end of the transmission rod is rotatably connected to one side of the bottom of the placement assembly.

[0016] By adopting the above technical solution, when the ball screw rotates, the ball block moves on the ball screw, and when the ball block moves to the top of the ball screw, it will automatically move downward. The transmission rod is hinged to the bottom of the ball block, so that when the ball block moves upward, the transmission rod pulls the bottom of the placement assembly to rotate the placement assembly, thereby completing the automatic dumping of the molten metal. The height of the ball screw is higher than the top of the placement assembly. When the ball block moves to the top of the ball screw, the transmission rod pulls the placement bucket in the placement assembly to rotate at an angle greater than 90 degrees, so that the molten metal in the placement bucket can flow out completely.

[0017] Furthermore, the placement assembly includes a placement bucket arranged on one side of the transmission rod, a placement plate symmetrically arranged on the top of the baffle, a fixed rod arranged on one side of the top of the placement plate, a rotating plate arranged on one side of the fixed rod, and the rotating plate is rotatably connected to the placement bucket, a pouring bucket arranged in the placement bucket, and a clamping ring arranged on the top of the pouring bucket.

[0018] With the above technical solution, the placement bucket is used to place the pouring bucket containing molten metal. Before casting, the clamping ring is clamped with a clip to lift the pouring bucket containing high-temperature molten metal and vertically place it into the placement bucket. The placement bucket is then rotated in the vertical direction through the driving assembly and the transmission assembly to pour the molten metal from the injection port, thereby improving production efficiency. By automatically pouring the molten metal, the time and cost of manual operation can be greatly reduced. Traditional manual pouring requires a lot of manpower and time, while automated pouring can quickly and accurately pour the molten metal into the desired position, thereby improving the efficiency of the entire production process. Product quality is guaranteed, ensuring that the molten metal is accurately poured into the desired position, and avoiding product quality problems caused by human factors.

[0019] Furthermore, support components are symmetrically arranged on both sides of the bottom of the placement bucket, and the support components include a support component arranged at the bottom of the placement bucket, and an extrusion and contraction component arranged at the top of the support component;

[0020] The support assembly includes a support block arranged on one side of the bottom of the barrel, a support member arranged inside the support block, a support column arranged on one side of the support member, an ejection slope opened on one side of the support column, and a support hole opened in the middle of the support column, and a first extrusion slope opened on one side of the support hole, and the top of the first extrusion slope abuts against the extrusion contraction assembly.

[0021] With the above technical solution, the support assembly is used to support the bottom of the pouring bucket when placing the pouring bucket filled with high-temperature molten metal, so as to prevent the pouring bucket from suddenly falling into the placing bucket when placed, causing the high-temperature molten metal in the pouring bucket to splash out and scald the staff, thereby improving the safety when pouring the liquid. In the initial state, one end of the support column is in an extended state, used to abut the bottom of the pouring bucket, and the support hole is used to shrink the support column backward when squeezed by the squeezing and shrinking assembly, so that the pouring bucket can fall down a distance. When the first squeezing slope is squeezed, the effect of the support column moving backward is completed. The ejection slope is used to squeeze the bottom of the pouring bucket when the support is reset, so that the pouring bucket slides along the ejection slope, so that the pouring bucket can be raised, which is convenient for the pouring bucket to be taken out after being clamped.

[0022] Furthermore, the extrusion and contraction assembly includes an extrusion long rod arranged on one side of the placement barrel, an extrusion long block arranged on one side of the top of the extrusion long rod, an extrusion and contraction groove opened on one side of the bottom of the rotating plate, and a first retaining surface opened on the rotating plate and located on one side of the extrusion and contraction groove, and the top of the extrusion long block abuts against the extrusion and contraction groove, and the bottom of the extrusion long rod abuts against one side of the first extrusion inclined surface.

[0023] By adopting the above technical scheme, in the initial state, the top of the extruded long block abuts against the bottom of the extrusion contraction groove, and at this time, the bottom of the extruded long rod abuts against the top of the first extrusion inclined surface. When the pouring bucket is driven to rotate, the rotating plate and the pouring bucket located in the pouring bucket rotate relatively. At this time, the extruded long block slides along one side of the extrusion contraction groove, so that the extruded long block is squeezed, thereby driving the extruded long rod to squeeze the first extrusion inclined surface, so that the support column shrinks. When the extruded long block rotates to the first retaining surface, the bottom of the extruded long rod is squeezed to the bottom of the first extrusion inclined surface, so that the support column is completely retracted into the placement bucket. At this time, the pouring bucket automatically falls under the action of its own weight, and after the pouring bucket falls, the edge position of its bottom is still on the ejection inclined surface, that is, it abuts against the bottom of the ejection inclined surface, so that when the support column is reset, the bottom edge of the pouring bucket can be ejected along the ejection inclined surface, so that the pouring bucket rises, and the clamping ring part is exposed, which is convenient for clamping when taking out.

[0024] Furthermore, clamping parts are symmetrically arranged on both sides of the top of the placing bucket, and the clamping parts include a clamping assembly arranged on one side of the top of the placing bucket, and an extrusion extension assembly arranged at the bottom of the clamping assembly;

[0025] The clamping assembly includes a clamping block arranged on one side of the top of the placement barrel, a clamping piece arranged inside the clamping block, a clamping column arranged on one side of the clamping piece, a clamping hole opened in the middle of the clamping column, a second extrusion inclined surface opened on one side of the clamping hole, a clamping groove opened on one side of the clamping column, and a lower sliding groove opened on the top of the placement barrel, and the lower sliding groove is slidably connected to the clamping ring, and the bottom of the second extrusion inclined surface abuts against the extrusion extension assembly.

[0026] The above technical solution is adopted, and the pouring bucket is clamped by setting a clamping assembly when pouring the molten metal, so as to avoid the pouring bucket from sliding after the bucket is turned over more than 90 degrees, thereby improving the stability and safety during pouring. When the clamping assembly is working, the clamping column is initially in a contracted state. When the first extrusion slope in the clamping column is squeezed, the clamping column slowly extends to clamp the top of the clamping ring on the top of the pouring bucket after it falls. The clamping groove is used to clamp the top of the clamping ring. When the pouring bucket is no longer supported by the support assembly, the pouring bucket falls along the drop groove, and the bottom of the clamping ring abuts against the bottom of the drop groove, so that the clamping groove and the bottom of the drop groove cooperate to clamp the pouring bucket in a limited position. It improves production efficiency, can quickly clamp and stabilize the pouring bucket, and make the pouring process more stable and efficient, thereby reducing the pouring time and improving production efficiency. The risk of the pouring bucket slipping or tilting during manual clamping and pouring, which would cause leakage of high-temperature molten metal, is avoided, thereby improving the safety of pouring.

[0027] Furthermore, the extrusion extension component includes an extrusion short rod arranged on the top of the rotating plate, an extrusion short block arranged on one side of the bottom of the extrusion short rod, an extrusion extension groove opened on the other side of the rotating plate, an abutment surface opened on one side of the extrusion extension groove, a rotating surface arranged on one side of the abutment surface, and a second retaining surface arranged on the rotating plate and located on one side of the extrusion extension groove, one side of the extrusion short block abuts against the abutment surface, and the top of the extrusion short rod abuts against one side of the second extrusion inclined surface.

[0028] The above technical solution is adopted, and the clamping assembly is used to clamp the pouring bucket through the extrusion extension assembly. When the rotating plate just starts to rotate, the extrusion contraction groove squeezes the extrusion long rod so that the support column can shrink first, and the extrusion short block rotates a distance on the rotating surface first, that is, the clamping block does not extend to clamp the clamping ring first. When the support column is fully contracted and the pouring bucket falls, the extrusion short block rotates to one side of the extrusion extension groove and pushes the extrusion short rod to squeeze the second extrusion inclined surface, so that the clamping column extends to clamp the pouring bucket. That is, when the rotating plate rotates, the extrusion long block is squeezed before the extrusion short block, so as to achieve clamping after the pouring bucket falls, and this process is realized synchronously during the rotation of the rotating pouring bucket, which not only realizes the automatic dumping of the molten metal, but also improves the safety during the dumping process; the setting of the abutment surface is used to make the extrusion short block abut against the abutment surface when the placement bucket is reset, so as to maintain the vertical state and avoid the shaking of the pouring bucket after reset.

[0029] Another aspect of the present application provides a casting method for GIS conductors, the purpose of which is to achieve rapid pouring during casting without manual pouring, thereby improving pouring and casting efficiency while improving safety.

[0030] The technical solution of the present invention is: before casting, the molten metal liquid is clamped by a clamping pliers with a clamping ring and then placed in a placement bucket, and the bottom of the placement bucket abuts against the support column;

[0031] The driving motor is started, and the driving motor drives the driving gear and the transmission gear to rotate, so that the ball screw rotates and drives the ball block to move upward, and the ball block moves on the ball screw and pulls the bottom of the placement barrel through the transmission rod, so that the placement barrel rotates;

[0032] During the rotation of the placement barrel, the rotating plate and the placement barrel rotate relative to each other, firstly causing the supporting component to retract into the placement barrel, and the pouring barrel falls a certain distance under the action of its own weight, so that the clamping ring abuts against the bottom of the sliding chute;

[0033] Subsequently, during the relative rotation of the rotating plate and the placing barrel, the clamping component extends to abut and clamp the top of the clamping ring, and during the rotation of the placing barrel to pour the molten metal, the placing barrel is clamped and poured;

[0034] The casting motor is started, so that the rotating rod belt drives the rotating disk to rotate, and the rotating disk drives the rotating rod to rotate, and the metal liquid poured into the upper mold and the lower mold is centrifugally cast.

[0035] Furthermore, the placement barrel rotates around the rotating rod under the cooperation of the ball screw and the transmission assembly, and the rotation angle of the placement barrel is an obtuse angle. After the ball block reaches the top, under the cooperation of the ball block and the ball screw, the ball block automatically reciprocates and moves downward after reaching the top of the ball screw, so that the placement barrel is reset. When it rotates to the initial position of the placement barrel, the ejection slope on the support column squeezes the bottom of the placement barrel, so that the placement barrel automatically pops out, which is convenient for taking out the placement barrel.

[0036] Compared with the prior art, the present invention has the following beneficial effects:

[0037] 1. The drive assembly and transmission assembly are used to rotate the placement barrel in the vertical direction, and the molten metal is poured from the injection port, which improves production efficiency. The automated pouring of molten metal can greatly reduce the time and cost of manual operation. Traditional manual pouring requires a lot of manpower and time, while automated pouring can quickly and accurately pour the molten metal into the desired position, thereby improving the efficiency of the entire production process. Product quality is guaranteed, ensuring that the molten metal is accurately poured into the desired position, and avoiding product quality problems caused by human factors.

[0038] 2. The support assembly is used to support the bottom of the pouring bucket when placing the pouring bucket filled with high-temperature molten metal, so as to prevent the pouring bucket from suddenly falling into the placement bucket when being placed, causing the high-temperature molten metal in the pouring bucket to splash out and scald the staff, thereby improving the safety when pouring the liquid.

[0039] 3. Through the cooperation of the clamping groove and the bottom of the drop groove, the pouring bucket is clamped in a limited position, which can improve production efficiency, quickly clamp and stabilize the pouring bucket, make the pouring process more stable and efficient, thereby reducing the pouring time and improving production efficiency. It also avoids the risk of the pouring bucket slipping or tilting during manual clamping and pouring, causing high-temperature molten metal to leak, and improves the safety of pouring.

DETAILED DESCRIPTION

[0053] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0054] Example 1, reference Figure 1-Figure 4, which is the first embodiment of the present invention, provides a casting device for GIS conductors, including a mounting frame and a casting motor 1 mounted at the bottom of the mounting frame, a protective cover 16 mounted at the top of the mounting frame, an upper mold 11 mounted in the middle of the mounting frame, a lower mold 12 mounted at the bottom of the upper mold 11, an injection port 13 mounted at the top of the upper mold 11, a rotating rod 14 mounted at the bottom of the lower mold 12, a baffle 17 mounted on one side of the top of the protective cover 16, and a rotating disk 15 mounted at the bottom of the rotating rod 14, and the rotating disk 15 and the casting motor 1 are driven by a belt, and also include a pouring component; the pouring component includes a driving component 2 mounted at the bottom of the baffle 17, and a transmission component mounted on one side of the driving component 2. , and a placement component 4 installed on one side of the driving component 2; the driving component 2 includes a driving motor 21 installed on one side of the top of the baffle 17, a driving tooth 22 fixedly connected to one end of the output shaft of the driving motor 21, a transmission tooth 23 meshingly connected to one side of the driving tooth 22, a ball screw 24 fixedly connected to the middle of the transmission tooth 23, and a support frame fixedly connected to the top of the baffle 17, and the two ends of the ball screw 24 are rotatably connected to the middle of the support frame and the baffle 17 respectively; the pouring component is used to pour the molten metal during casting, and the driving component 2 drives the placement component 4 to rotate through the transmission component, so that the molten metal in the placement component 4 is poured from the injection port 13 into the upper mold 11 and the lower mold 12 for casting.

[0055] Specifically, the automatic pouring of the molten metal during centrifugal casting is realized by the provided pouring component, and the molten metal flows into the space between the upper mold 11 and the lower mold 12 through the injection port 13. Driven by the casting motor 1, the belt drives the rotating disk 15 to rotate, the rotating disk 15 drives the rotating rod 14 to rotate, and the rotating rod 14 drives the upper mold 11 and the lower mold 12 to rotate, so that the molten metal injected into the upper mold 11 and the lower mold 12 fills the internal mold groove under the action of the rotating centrifugal force, and the casting is completed. When the pouring component is working, the driving component 2 drives the transmission component to rotate the placement component 4 through the driving component 2, and the pouring of the molten metal during casting is completed. When the driving component 2 is working, the output shaft of the driving motor 21 drives the driving gear 22 to rotate, the driving gear 22 drives the transmission gear 23 to rotate, and the transmission gear 23 drives the ball screw 24 to rotate, and the ball screw 24 rotates so that the transmission component moves on the ball screw 24, and the ball screw 24 is limited at the top of the support frame.

[0056] Reference Figure 1-Figure 5 The transmission assembly includes a ball block 3 slidably connected to the ball screw 24, and a transmission rod 31 rotatably connected to the bottom of one side of the ball block 3, and one end of the transmission rod 31 is rotatably connected to one side of the bottom of the placement assembly 4.

[0057] Specifically, when the ball screw 24 rotates, the ball block 3 moves on the ball screw 24, and when the ball block 3 moves to the top of the ball screw 24, it will automatically move downward, and the transmission rod 31 is hinged to the bottom of the ball block 3, so that when the ball block 3 moves upward, the transmission rod 31 pulls the bottom of the placement component 4 to make the placement component 4 rotate, thereby completing the automatic dumping of the molten metal, and the height of the ball screw 24 is higher than the top of the placement component 4. When the ball block 3 moves to the top of the ball screw 24, the transmission rod 31 pulls the placement barrel 41 in the placement component 4 to rotate by an angle greater than 90 degrees, so that the molten metal in the placement barrel 41 can all flow out.

[0058] Reference Figure 1-Figure 6 The placement component 4 includes a placement barrel 41 rotatably connected to one side of the transmission rod 31, a placement plate symmetrically fixedly connected to the top of the baffle 17, a fixed rod 42 fixedly connected to one side of the top of the placement plate, a rotating plate 43 fixedly connected to one side of the fixed rod 42, and the rotating plate 43 is rotatably connected to the placement barrel 41, a pouring barrel 44 installed in the placement barrel 41, and a clamping ring 45 fixedly connected to the top of the pouring barrel 44.

[0059] Specifically, the placement bucket 41 is used to place the pouring bucket 44 filled with molten metal. Before casting, the clamping ring 45 is clamped with a clip, the pouring bucket 44 filled with high-temperature molten metal is lifted, and then placed vertically into the placement bucket 41. The placement bucket 41 is then rotated in the vertical direction through the driving component 2 and the transmission component to pour the molten metal from the injection port 13, thereby improving production efficiency. By automatically pouring the molten metal, the time and cost of manual operation can be greatly reduced. Traditional manual pouring requires a lot of manpower and time, while automated pouring can quickly and accurately pour the molten metal into the desired position, thereby improving the efficiency of the entire production process. The product quality is guaranteed, ensuring that the molten metal is accurately poured into the desired position, and avoiding product quality problems caused by human factors.

[0060] Example 2, reference Figure 1-Figure 8 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: support components are symmetrically installed on both sides of the bottom of the placement barrel 41, and the support components include a support assembly 5 installed at the bottom of the placement barrel 41, and an extrusion and contraction assembly 6 installed on the top of the support assembly 5; the support assembly 5 includes a support block 51 fixedly connected to one side of the bottom of the placement barrel 41, a support member 52 fixedly connected to the inside of the support block 51, a support column 53 fixedly connected to one side of the support member 52, an ejection slope 54 opened on one side of the support column 53, a support hole 55 opened in the middle of the support column 53, and a first extrusion slope 56 opened on one side of the support hole 55, and the top of the first extrusion slope 56 abuts against the extrusion and contraction assembly 6.

[0061] Specifically, the support assembly 5 is used to support the bottom of the pouring bucket 44 when placing the pouring bucket 44 filled with high-temperature molten metal, so as to prevent the pouring bucket 44 from suddenly falling into the placement bucket 41 when placed, so that the high-temperature molten metal in the pouring bucket 44 splashes out and scalds the staff, thereby improving the safety of pouring. In the initial state, one end of the support column 53 is in an extended state, which is used to abut the bottom of the pouring bucket 44. The support hole 55 is used to shrink the support column 53 backward when squeezed by the squeezing and shrinking assembly 6, so that the pouring bucket 44 can fall down a distance. When the first squeezing slope 56 is squeezed, the effect of the support column 53 moving backward is completed. The ejection slope 54 is used to squeeze the bottom of the pouring bucket 44 when the support member 52 is reset, so that the pouring bucket 44 slides along the ejection slope 54, so that the pouring bucket 44 can be lifted, which is convenient for the pouring bucket 44 to be taken out after being clamped.

[0062] Reference Figure 1-Figure 9 The extrusion and contraction assembly 6 includes an extrusion long rod 61 slidably connected to one side of the placement barrel 41, an extrusion long block 62 fixedly connected to one side of the top of the extrusion long rod 61, and an extrusion and contraction groove 63 opened on one side of the bottom of the rotating plate 43, and a first retaining surface 64 opened on the rotating plate 43 and located on one side of the extrusion and contraction groove 63, and the top of the extrusion long block 62 abuts against the extrusion and contraction groove 63, and the bottom of the extrusion long rod 61 abuts against one side of the first extrusion inclined surface 56.

[0063] Specifically, in the initial state, the top of the extrusion long block 62 abuts against the bottom of the extrusion contraction groove 63, and at this time, the bottom of the extrusion long rod 61 abuts against the top of the first extrusion inclined surface 56. When the pouring bucket 44 is driven to rotate, the rotating plate 43 and the pouring bucket 44 located in the pouring bucket 44 rotate relatively. At this time, the extrusion long block 62 slides along one side of the extrusion contraction groove 63, so that the extrusion long block 62 is squeezed, thereby driving the extrusion long rod 61 to squeeze the first extrusion inclined surface 56, so that the support column 53 shrinks. When the extrusion long block 62 rotates to the first extrusion contraction groove 63, the extrusion long block 62 is squeezed, thereby driving the extrusion long rod 61 to squeeze the first extrusion inclined surface 56, so that the support column 53 shrinks. When the support column 53 is on the first holding surface 64, the bottom of the extrusion rod 61 is squeezed to the bottom of the first extrusion slope 56, so that the support column 53 is completely retracted into the placement bucket 41. At this time, the pouring bucket 44 automatically falls under the action of its own weight, and after the pouring bucket 44 falls, the edge position of its bottom is still on the ejection slope 54, that is, it abuts against the bottom of the ejection slope 54, so that when the support column 53 is reset, the bottom edge of the pouring bucket 44 can be ejected along the ejection slope 54, so that the pouring bucket 44 rises, and the clamping ring 45 is partially exposed, which is convenient for clamping when taking out. The rest of the structure is the same as that of Example 1.

[0064] Example 3, reference Figure 1-Figure 10, which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: clamping components are symmetrically installed on both sides of the top of the placement bucket 41, and the clamping components include a clamping assembly 7 installed on one side of the top of the placement bucket 41, and an extrusion extension assembly 8 installed at the bottom of the clamping assembly 7; the clamping assembly 7 includes a clamping block 71 fixedly connected to one side of the top of the placement bucket 41, a clamping member 72 fixedly connected to the inside of the clamping block 71, a clamping column 73 fixedly connected to one side of the clamping member 72, a clamping hole 74 opened in the middle of the clamping column 73, a second extrusion inclined surface 75 opened on one side of the clamping hole 74, a clamping groove 76 opened on one side of the clamping column 73, and a lower sliding groove 77 opened on the top of the placement bucket 41, and the lower sliding groove 77 is slidably connected to the clamping ring 45, and the bottom of the second extrusion inclined surface 75 abuts against the extrusion extension assembly 8, and the clamping member 72 and the support member 52 can be springs.

[0065] Specifically, by setting the clamping assembly 7 to clamp the pouring bucket 44 when pouring the molten metal, the pouring bucket 44 is prevented from sliding down after the placement bucket 41 is turned over more than 90 degrees, thereby improving the stability and safety during pouring. When the clamping assembly 7 is working, the clamping column 73 is initially in a contracted state. When the first extrusion slope 56 in the clamping column 73 is squeezed, the clamping column 73 slowly extends to clamp the top of the clamping ring 45 on the top of the fallen pouring bucket 44. The clamping groove 76 is used to clamp the top of the clamping ring 45. When the pouring bucket 44 is no longer supported by the support assembly 5, the pouring bucket 44 falls along the drop groove, and the bottom of the clamping ring 45 abuts against the bottom of the drop groove, so that the clamping groove 76 cooperates with the bottom of the drop groove to clamp the pouring bucket 44 in a limited position. Improve production efficiency, can quickly clamp and stabilize the pouring bucket 44, make the pouring process more stable and efficient, thereby reducing the pouring time and improving production efficiency. Avoid the risk of the pouring bucket 44 slipping or tilting during manual clamping and pouring, causing high-temperature molten metal to leak, and improve pouring safety.

[0066] Reference Figure 1-Figure 11 The extrusion extension component 8 includes an extrusion short rod 81 abutting against the top of the rotating plate 43, an extrusion short block 82 fixedly connected to one side of the bottom of the extrusion short rod 81, an extrusion extension groove 83 opened on the other side of the rotating plate 43, an abutment surface 84 opened on one side of the extrusion extension groove 83, a rotating surface 85 opened on one side of the abutment surface 84, and a second retaining surface 86 opened on the rotating plate 43 and located on one side of the extrusion extension groove 83, one side of the extrusion short block 82 abuts against the abutment surface 84, and the top of the extrusion short rod 81 abuts against one side of the second extrusion inclined surface 75.

[0067] Specifically, the clamping assembly 7 is used to clamp the pouring bucket 44 by the extrusion extension assembly 8. When the rotating plate 43 just starts to rotate, the extrusion contraction groove 63 squeezes the extrusion long rod 61 so that the support column 53 can be contracted first, and the extrusion short block 82 rotates on the rotating surface 85 for a distance first, that is, the clamping block 71 does not extend to clamp the clamping ring 45 first. When the support column 53 is completely contracted, the pouring bucket 44 falls, and the extrusion short block 82 rotates to one side of the extrusion extension groove 83, and pushes the extrusion short rod 81 to squeeze the second extrusion inclined surface 75, so that the clamping column 73 extends to clamp the pouring bucket 44. That is, when the rotating plate 43 rotates, the extrusion long block 62 is squeezed before the extrusion short block 82, so that the pouring bucket 44 is clamped after it falls, and this process is synchronously realized during the rotation of the rotating pouring bucket 44, which not only realizes the automatic pouring of the molten metal, but also improves the safety during the pouring process. The abutment surface 84 is provided to ensure that when the placing bucket 41 is reset, the short block 82 is pressed against the abutment surface 84 to limit the position, so as to maintain the vertical state and avoid the shaking of the pouring bucket 44 after reset. The rest of the structure is the same as that of the second embodiment.

[0068] Example 4, reference Figure 1-Figure 11 , which is a fourth embodiment of the present invention, provides a casting method for a GIS conductor, using the above-mentioned casting device for a GIS conductor, comprising the following steps:

[0069] S1 Before casting, the molten metal is clamped by a clamping pliers with a clamping ring 45 and then placed in a placing bucket 41 , and the bottom of the placing bucket 41 abuts against the supporting column 53 .

[0070] S2 starts the driving motor 21, which drives the driving gear 22 and the transmission gear 23 to rotate, so that the ball screw 24 rotates to drive the ball block 3 to move upward, and the ball block 3 moves on the ball screw 24 and pulls the bottom of the placement barrel 41 through the transmission rod 31, so that the placement barrel 41 rotates.

[0071] S3 During the rotation of the placement barrel 41 , the rotating plate 43 and the placement barrel 41 rotate relative to each other, firstly causing the support component to retract into the placement barrel 41 , and the pouring barrel 44 falls a certain distance under the action of its own weight, so that the clamping ring 45 abuts against the bottom of the lower slide groove 77 .

[0072] S4: Subsequently, during the relative rotation of the rotating plate 43 and the placing barrel 41, the clamping member extends to abut against and clamp the top of the clamping ring 45, and during the rotation of the placing barrel 41 to pour the molten metal, the placing barrel 41 is clamped and poured;

[0073] S5: Start the casting motor 1, so that the rotating rod 14 drives the rotating disk 15 to rotate, and the rotating disk 15 drives the rotating rod 14 to rotate, so as to centrifugally cast the molten metal poured into the upper mold 11 and the lower mold 12.

[0074] S6 The placement barrel 41 rotates around the rotating rod 14 under the cooperation of the ball screw 24 and the transmission assembly, and the rotation angle of the placement barrel 41 is an obtuse angle. After the ball block 3 reaches the top, under the cooperation of the ball block 3 and the ball screw 24, the ball block 3 automatically moves back and forth downward after reaching the top of the ball screw 24, so that the placement barrel 41 is reset. When it rotates to the initial position of the placement barrel 41, the ejection slope 54 on the support column 53 squeezes the bottom of the placement barrel 41, so that the placement barrel 41 automatically pops out, which is convenient for taking out the placement barrel 41.

[0075] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
