Description

Technical Field

[0001] The invention relates to the technical field of casting pouring, and in particular to a casting device and a process thereof for improving the eccentricity of a ceramic core in casting pouring. Background Art

[0002] Investment casting is mainly used in the production of steam turbines, gas turbines and complex instrument components due to its advantages of high dimensional accuracy, no parting surface, and a wide range of applicable alloys. These complex castings, especially multi-blade castings with ceramic cores, are mainly fixed by connecting the core heads on both sides to the mold shell. The connection is often completely fixed on one side, and there is a gap on the other side to reduce the risk of core breakage. However, when the riser is facing the ceramic core (such as Fig.14 As shown in the figure), during the pouring process, the metal liquid flows at a high speed and the impact pressure increases. At this time, the ceramic core cannot withstand the pressure, resulting in a core eccentricity problem. Therefore, the present invention proposes a pouring device and a process for improving the core eccentricity of the casting ceramic core to solve the above problem. Summary of the invention

DETAILED DESCRIPTION

[0017] The preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention can be implemented in various forms, so the present invention is not limited to the embodiments described below. In addition, in order to more clearly describe the present invention, components that are not connected with the invention will be omitted from the drawings. The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows: Example

[0018] Please refer to Figure 1-Figure 5 As shown, this embodiment introduces a specific structure of a pouring device for improving the eccentricity of a casting ceramic core, comprising a casting ceramic mold shell 1 and a bracket 4, a necking opening 2 is arranged in the middle of the casting ceramic mold shell 1, a ceramic plug 3 is arranged inside the casting ceramic mold shell 1, and a conveying component 5, a discharge component 6, and a heat preservation component 7 are arranged on the upper side of the bracket 4; Specifically, before pouring molten metal into the interior of the casting ceramic mold shell 1, the pipeline path on the lower side of the necking port 2 is blocked by the ceramic plug 3, and then the flow path of the molten metal inside is changed by the ceramic plug 3, and the conveying component 5 is used to drive the movement of the casting ceramic mold shell 1, and the discharge component 6 is used to automatically put the ceramic plug 3 into the interior of the casting ceramic mold shell 1. After pouring molten metal into the interior, the huge temperature difference between the inside and the outside of the molten metal when cooling may cause the casting ceramic mold shell 1 to break. Therefore, before pouring molten metal, the casting ceramic mold shell 1 needs to be wrapped with insulation material, and the insulation component 7 is used for the automatic wrapping of insulation material; The conveying assembly 5 includes two rotating shafts 501, which are rotatably connected to the left and right sides of the bracket 4 respectively, and the rear ends of the two rotating shafts 501 are fixedly connected with gears 502, a chain 503 is sleeved between the two gears 502, and a plurality of racks 504 are fixedly connected to the chain 503, a gear 2 505 is fixedly connected to the middle part of the left rotating shaft 501, a two-way threaded shaft 506 is rotatably connected to the left side of the bracket 4, a gear 3 507 is fixedly connected to the front end of the two-way threaded shaft 506, a chain 2 508 is arranged between the front and rear sides of the gear 2 505 and the gear 3 507, and a plurality of driving rods 509 are fixedly connected between the two chains 2 508, a motor 1 510 is fixedly connected to the front end of the bracket 4, a rotating shaft 2 511 is fixedly connected to the output end of the motor 1 510, and two gears 4 512 are fixedly connected to the middle part of the rotating shaft 2 511, and the two gears 4 512 are respectively meshed with the two chains 2 508; The motor drives the rotating shaft 2 511 to rotate and then drives the two gears 4 512 to rotate. The two gears 4 512 are respectively meshed with the two chains 2 508, and then drive the two chains 2 508 to rotate. When the two chains 2 508 rotate, they will drive the driving rod 509 to rotate. Since the driving rod 509 is only partially provided between the two chains 2 508, the driving rod 509 drives the gear 3 507 and the toothed claws on the gear 2 505, and then drives the gear 3 507 and the gear 2 505 to rotate. The length of multiple driving rods 509 on the chain 2 508 can just drive the gear 2 505 to rotate one circle, and drive the gear 3 507 to rotate two circles at the same time. Note that the driving rod 509 drives the gear 3 507 and the gear 2 505 to move in a regular manner. The law is that first, the gear 2 505 is driven to rotate one circle, and then the gear 3 507 is driven to rotate one circle. After the gear 3 507 rotates one circle, there is a period of time in the middle when the motor 1 510 is in an off state. When the motor 1 510 is started again, it continues to drive the gear 3 507 to rotate one circle, and the process is repeated in sequence. The gear 2 505 rotates one circle, and the left gear 1 502 can be driven to rotate one circle through the rotating shaft 1 501. The gear 1 502 rotates one circle to drive the chain 1 503 to move and the rack 504 to move at the same time. The gear 1 502 rotates one circle just to move the distance from the rear rack 504 to the position of the front rack 504. By placing the casting ceramic mold shell 1 in the middle of the rack 504, the casting ceramic mold shell 1 can be driven to move. Please refer to Figure 1 , Figure 6-Figure 11As shown, the discharge assembly 6 includes a material bin 1 601, which is fixedly connected to the right side of the bracket 4, an equipment compartment 1 602 is arranged inside the material bin 1 601, a motor 2 603 is fixedly connected inside the equipment compartment 1 602, a rotating shaft 3 604 is rotatably connected inside the equipment compartment 1 602, a pulley group 1 605 is arranged between the rotating shaft 3 604 and the output end of the motor 2 603, a bevel gear a 606 is fixedly connected to the middle of the rotating shaft 3 604, and a rotating shaft 4 is rotatably connected to the middle of the equipment compartment 1 602 607, the front end of the rotating shaft 4 607 is rotatably connected with a bevel gear b608, the bevel gear b608 is meshed with the bevel gear a606, the rear end of the bevel gear a606 is fixedly connected with a cam 609, a moving plate 1 610 is arranged inside the material bin 1 601, the rear side of the moving plate 1 610 is fixedly connected with a moving plate 2 611, the interior of the material bin 1 601 is fixedly connected with a fixed plate 612, the interior of the material bin 1 601 is rotatably connected with two screw conveying rollers 613, the right ends of the two screw conveying rollers 613 are rotatably connected There is a gear five 614, and the two gear fives 614 are meshed with each other. A pulley group two 615 is arranged between the left end of the front threaded conveying roller 613 and the left end of the rotating shaft three 604. The interior of the material bin one 601 is rotatably connected to two rotating rollers 616, and a conveyor belt 618 is sleeved between the two rotating rollers 616. A pulley group three 617 is arranged between the left end of the upper rotating roller 616 and the left end of the rotating shaft three 604. A feeding trough 619 is arranged inside the material bin one 601, and a partition plate is fixedly connected inside the material bin one 601. 620, a material delivery pipe 1 621 is fixedly connected to the upper left end of the material bin 1 601, and a fixed plate 622 is fixedly connected to the end of the material delivery pipe 1 621 away from the material bin 1 601, and a material slot 1 623 and a material slot 2 624 are provided inside the fixed plate 622, and a rotating plate 625 is rotatably connected inside the fixed plate 622, and a material slot 3 626 is provided inside the rotating plate 625, and a torsion spring 627 is fixedly connected between the rotating plate 625 and the material slot 3 626, and a limiting block 628 is fixedly connected to the right side of the rotating plate 625; The feed trough 619 is designed in a "U" shape inside the material bin 1 601. The two threaded conveying rollers 613 are both arranged on the front side of the top end of the fixed plate 612. The movable plate 1 610 and the movable plate 2 611 are respectively slidably connected to the front and rear sides of the fixed plate 612. The material separator 620 is arranged on the rear side of the top end of the movable plate 2 611. The two rotating rollers 616 are longitudinally arranged on the lower side of the rear end of the material separator 620. The feed pipe 1 621 is connected with the material bin 1 601. The material trough 2 624 is consistent with the output end opening position of the feed pipe 1 621. The position of the material trough 1 623 is offset to the right by about 45 degrees compared with the position of the material trough 2 624. The position of the material trough 3 626 corresponds to the channel position of the feed pipe 1 621. A plurality of ceramic plugs 3 are placed inside the material bin 601, and the interior of the material bin 601 is divided by a partition plate 620. A plurality of ceramic plugs 3 are placed on top of the partition plate 620. The movable plate 1 610 and the movable plate 2 611 are connected and move up and down on the front and back sides of the fixed plate 612. When both move to the lowest side, the top of the motor 1 510 is flush with the top of the fixed plate 612, and the top of the movable plate 2 611 is flush with the front end of the partition plate 620. The partition plate 620 is cut low at the front and high at the back and is fixed obliquely inside the material bin 601. When the movable plate 1 610 and the movable plate 2 611 move to the highest side, the top of the movable plate 1 610 is flush with the tops of the two threaded conveying rollers 613, and the top of the movable plate 2 611 is flush with the tops of the two threaded conveying rollers 613. The end is flush with the top of the fixed plate 612. Since the thickness of the movable plate 1 610 and the movable plate 2 611 is the same as the diameter of the ceramic plug 3, and the ceramic plug 3 is of the same conical design, when the movable plate 1 610 and the movable plate 2 611 drive the ceramic plug 3 to move up, they can only move up and down with one row of ceramic plugs 3 in turn, and the other ceramic plugs 3 fall back to the top of the partition plate 620 under the obstruction of the ceramic plugs 3 at the top of the movable plate 1 610 and the movable plate 2 611. Therefore, the ceramic plug 3 at the top of the partition plate 620 is pushed to the top of the fixed plate 612 by the up and down movement of the movable plate 2 611, and the ceramic plug 3 at the top of the fixed plate 612 is pushed to between the tops of the two threaded conveying rollers 613 when the movable plate 1 610 moves up and down. The motor 2 603 drives the rotating shaft 3 604 to rotate through the pulley group 1 605, and the rotating shaft 3 604 drives the bevel gear a 606 to drive the bevel gear b 608 to rotate, and then drives the rotating shaft 4 607 to rotate, and the rotating shaft 4 607 drives the cam 609 to rotate, and then drives the moving plate 1 610 to move up and down, and at the same time, the rotating shaft 3 604 drives the front side thread conveying roller 613 to rotate through the pulley group 2 615, and the front side thread conveying roller 613 drives the rear side gear 5 614 through the front side gear 5 614, and then the two thread conveying rollers 613 rotate in opposite directions at the same time, and the ceramic plugs 3 at the top ends of the two thread conveying rollers 613 are pushed to the left by the push of the threads, and then the ceramic plugs 3 are conveyed to the inside of the feeding pipe 1 621; The movable plate 1 610 and the movable plate 2 611 will continuously push the ceramic plugs 3 on the top of the partition plate 620 to the top of the two threaded conveying rollers 613. When there are too many ceramic plugs 3 on the top of the two threaded conveying rollers 613, the excess ceramic plugs 3 will fall from the feed trough 619 to the bottom of the material bin 1 601. When the rotating shaft 3 604 rotates, it drives the upper rotating roller 616 to rotate through the pulley group 3 617, and drives the conveyor belt 618 to rotate counterclockwise through the rotating roller 616. When the conveyor belt 618 rotates, the scraper on the outside of it will drive the ceramic plugs 3 on the bottom of the material bin 1 601 to move. The gap between the scraper and the inner wall of the material bin 1 601 is small, and the ceramic plugs 3 cannot fall, so the conveyor belt 618 will bring the ceramic plugs 3 to the top of the partition plate 620. The ceramic plug 3 inside the feeding pipe 1 621 will first fall into the inside of the material slot 3 626, but it cannot continue to fall due to the obstruction of the fixed plate 622. When the rack 504 is moving, one end of the rack 504 will push the rotating plate 625 to rotate, and the material slot 3 626 will bring the ceramic plug 3 inside the material slot 3 626 to the material slot 1 623 as the rotating plate 625 rotates. The ceramic plug 3 inside the material slot 3 626 will naturally fall into the inside of the material slot 1 623 and move to the middle of the material slot 3 626 again. The rack 504 will move to the middle of the material slot 3 626. When the rack 504 continues to move forward, the front end of the moving direction of the rack 504 cannot push the rotating disk 625 to rotate due to the limitation of the moving distance. The rotating disk 625 will return to its original position under the rebound force of the torsion spring 627, and the bottom of the rotating disk 625 will move to the middle of the rack 504 to reset. At this time, the material slot 3 626 will overlap with the material slot 2 624 again, so the ceramic plug 3 in the middle of the material slot 3 626 will pass through the material slot 2 624 and slide from the lower side of the material slot 3 626 to the inside of the casting ceramic mold shell 1, and then block the neck opening 2. Please refer to Figure 1 , Figure 12-13 As shown, the insulation component 7 includes two moving blocks 701, and the two moving blocks 701 are both threadedly connected to the outside of the two-way threaded shaft 506. The tops of the two closed cabins 702 are fixedly connected to the closed cabins 702. The left side of the bracket 4 is rotatably connected to the material warehouse 2 703. The interior of the material warehouse 2 703 is respectively provided with an equipment cabin 2 704 and a storage warehouse 706. The interior of the equipment cabin 2 704 is fixedly connected to an air pressure pump 705. The input end of the air pressure pump 705 is connected to the outer side of the material warehouse 2 703. The output end of the air pump 705 is connected to the interior of the storage bin 706. A cover 707 is provided on the top of the storage bin 706. The bottom end of the second material bin 703 is fixedly connected with a second feed pipe 708. The second feed pipe 708 is connected to the interior of the storage bin 706. One end of the second feed pipe 708 away from the second material bin 703 is fixedly connected to two shrink hoses 709. One end of the two shrink hoses 709 away from the second feed pipe 708 is fixedly connected to the top of the two closed cabins 702 respectively. The above-mentioned insulation material is polystyrene foam material, which is a liquid material inside the storage bin 706. When it is transported between the two closed cabins 702, it foams, expands and solidifies, and wraps around the outside of the casting ceramic mold shell 1 to form an insulation layer; When the storage rack 504 drives the casting ceramic mold shell 1 to move between the two closed cabins 702, the bidirectional threaded shaft 506 rotates to drive the two moving blocks 701 to move to the opposite sides of the two at the same time, and then the casting ceramic mold shell 1 is stuck between the two closed cabins 702. When the front moving block 701 moves to the rear side, the front moving block 701 contacts the trigger switch 710. At this time, the motor 1 510 is turned off, and the air pressure pump 705 is started. The air pressure pump 705 transports gas to the inside of the storage bin 706. The air pressure inside the storage bin 706 increases, and the insulation material liquid inside the storage bin 706 passes through the feed pipe 2 708 and then through the shrink hose 709 until it is transported to between the two closed cabins 702. The insulation material liquid between the two closed cabins 702 foams, expands and solidifies, and is wrapped around the outside of the casting ceramic mold shell 1 to form an insulation layer. Note that the air pump 705 automatically shuts down after being started for a certain period of time. During this period of time, the insulation material it delivers just meets the amount required by the insulation layer. After the motor 510 is shut down, it will also automatically start within a period of time. The time from shutting down to starting up just meets the filling and curing of the insulation material. After the motor 510 is restarted, it first drives the two-way threaded shaft 506 to rotate, and then opens the two sealed cabins 702. When the two-way threaded shaft 506 rotates one circle again, the driving rod 509 drives the gear 2 505 and then drives the chain 1 503 to move through the gear 1 502, and drives the casting ceramic mold shell 1 to move through the storage rack 504 to carry out the insulation material wrapping work of the next casting ceramic mold shell 1.
