Description

Technical Field

[0001] The invention relates to the technical field of metal casting, and more particularly to aluminum shell casting equipment for a chemical centrifugal pump. Background Art

[0002] During the production of chemical centrifugal pumps, an aluminum shell is required as the outer shell of the chemical centrifugal pump for installation. During the production of the aluminum shell, casting equipment is required to achieve mass production. During the production process of the casting equipment, molten aluminum is poured into the mold, and then cooled and solidified to obtain the aluminum shell.

[0003] After the molten aluminum liquid has cooled and solidified, the mold needs to be separated to remove the aluminum shell formed inside the mold. Since the solidified aluminum shell is in close contact with the surface of the mold cavity, a negative pressure will be formed between the two during the mold separation process, causing the aluminum shell and the mold to be adsorbed. When external force is applied to separate the mold, the aluminum shell will be subjected to the tensile force generated by the separation. This tensile force can easily cause the aluminum shell to deform, thereby adversely affecting the casting production quality of the aluminum shell. Summary of the Invention

[0004] In view of the problems existing in the prior art, the purpose of the present invention is to provide a chemical centrifugal pump aluminum shell casting device to solve the problem that when the mold is separated, the aluminum shell will be subjected to the tensile force generated by the separation effect, which can easily cause the aluminum shell to deform.

[0005] To solve the above problems, the present invention adopts the following technical solutions.

[0010] Furthermore, a tension spring is fixedly connected to the right end of the cleaning splicing plate, and the right end of the tension spring is fixedly connected to the inside of the inner mold.

[0011] Furthermore, the engaging block is a hexagonal prism structure, six guide pieces are fixedly connected to the upper surface of the rotating block, and a cover plate is fixedly connected to the output shaft of the motor.

[0012] Furthermore, the rear surface of the slider is rotatably connected to a rotating shaft, the surface of the rotating shaft is fixedly connected to a rocker, the surface of the rotating shaft is fixedly connected to a hook rod, and the upper end of the pillar is fixedly connected to a fixed rod.

[0013] Furthermore, a rotating rod is rotatably connected to the surface of the pillar, and a rotating hook is fixedly connected to the surface of the rotating rod.

[0014] Furthermore, the arc surface of the rotating rod is fixedly connected with an elastic sheet, the surface of the pillar is fixedly connected with a limiting column, the elastic sheet is inserted into the interior of the limiting column, and the top end of the rotating hook sheet is fixedly connected with a guide sheet.

[0018] (3) This solution uses a spring to push the cutting piece out of the cleaning splicing plate and at the same time makes the cutting piece stick to the inner wall of the movable mold, which can drive the cutting piece to slide on the inner wall of the movable mold, making up for the defect that the arc surface angle of the cleaning splicing plate is different from the angle of the inner arc surface of the movable mold and cannot be completely fitted, resulting in the smaller and thinner aluminum chips cannot be cleaned due to impact, and further cleans the aluminum slag on the inner arc surface of the movable mold, reducing the intensity of subsequent cleaning operations.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figures 1-4 A chemical centrifugal pump aluminum shell casting device includes an equipment base 1, a fixed mold 2 is fixedly connected to the surface of the equipment base 1, a hydraulic rod 401 is fixedly connected to the surface of the equipment base 1, and the hydraulic rod 401 can be used as a power source for separating the movable mold 3, a movable mold 3 is provided on the surface of the equipment base 1, and an inner mold 409 is rotatably connected to the interior of the fixed mold 2, and a mold separation mechanism is provided inside the movable mold 3, and the mold separation mechanism includes multiple groups of push-pull rods 402 inserted into the movable mold 3, and one end of the multiple groups of push-pull rods 402 located inside the movable mold 3 is fixedly connected to a stripping splicing plate 403. The segmented stripping method achieved by stripping the splicing plate 403 can reduce the probability of deformation of the aluminum shell. The power output end of the hydraulic rod 401 is fixedly connected to a connecting frame 404, and the connecting frame 404 is fixedly connected to multiple groups of the push-pull rods 402. The stripping splicing plate 403 is arc-shaped and has the same curvature as the inner wall of the movable mold 3. The top of the fixed mold 2 is fixedly connected to a pouring bucket 510, and the upper and lower ends of the side of the fixed mold 2 are fixedly connected to connecting columns 406. A connecting groove 408 is provided on the surface of the connecting column 406. When the pulling column 407 moves to the end of the connecting groove 408, the movable mold 3 can be pulled apart from the fixed mold 2. A pulling column 407 is inserted into the inside of the connecting groove 408. A stretching frame 405 is fixedly connected between the two pulling columns 407. The middle part of the stretching frame 405 is fixedly connected to the power output end of the hydraulic rod 401.

[0023] By adopting the above technical solution, when casting the aluminum shell, the molten aluminum is poured into the casting bucket 510, and the aluminum liquid can flow into the gap between the movable mold 3 and the inner mold 409. After the aluminum liquid cools and solidifies, the hydraulic rod 401 can be used to pull the connecting frame 404 to move to the left. In the process of the connecting frame 404 moving to the left, the stripping splicing plate 403 will also be synchronously driven to move to the left, so that multiple stripping splicing plates 403 are separated from the surface of the aluminum shell. When the movable mold 3 contacts the aluminum shell, it can play the purpose of locally supporting the aluminum shell, thereby reducing the probability of deformation of the aluminum shell. As the hydraulic rod 401 continues to pull the connecting frame 404 to the left, it will also synchronously drive the stretching frame 405 and the pulling column 407 to move to the left, until the pulling column 407 moves to the end of the connecting groove 408. The pulling force acts on the connecting column 406, which can pull the movable mold 3 to the left, thereby realizing the separation of the movable mold 3 and the fixed mold 2, and then the aluminum shell is taken out to complete the casting of the aluminum shell.

[0024] like Figure 2 、 Figure 5-Figure 12 As shown, the aluminum slag processing mechanism is arranged inside the inner mold 409, and the aluminum slag processing mechanism includes a cleaning splicing plate 507 that is slidably connected to the inner mold 409. The aluminum slag on the inner arc surface of the movable mold 3 can be cleaned by cleaning the splicing plate 507. The right end of the cleaning splicing plate 507 is fixedly connected to the extrusion plate 506. A push rod 505 is inserted into the interior of the inner mold 409. The push rod 505 can be used to transmit power while allowing the cleaning splicing plate 507 to be removed from the inner mold 409. Extrusion, the top of the push rod 505 is fixedly connected to the rotating block 504, the rear surface of the equipment base 1 is fixedly connected to the pillar 501, the internal sliding connection of the pillar 501 is connected to the slider 512, the front surface of the slider 512 is fixedly connected to the motor 502, the output shaft of the motor 502 is fixedly connected to the matching block 511, the upper surface of the rotating block 504 is provided with a groove adapted to the matching block 511, and the matching block 511 is inserted into the groove on the surface of the rotating block 504 to realize the transmission of power from the motor 502.

[0025] Among them, the right end of the cleaning splicing plate 507 is fixedly connected with a tension spring 525, and the right end of the tension spring 525 is fixedly connected to the inside of the inner mold 409. After the pressure on the push rod 505 is released, the tension spring 525 can pull the cleaning splicing plate 507 back into the inner mold 409. The fitting block 511 is a hexagonal prism structure, and the upper surface of the rotating block 504 is fixedly connected with six guide pieces 503. The fitting block 511 can be aligned with the groove through the guidance of the guide piece 503, so that the fitting block 511 can accurately enter the groove. The output shaft of the motor 502 is fixedly connected to a cover plate 509, which can reduce the probability of aluminum liquid dripping into the groove during the pouring process. The rear surface of the slider 512 is rotatably connected to a rotating shaft 514, and the surface of the rotating shaft 514 is fixedly connected to a rocker 513, and the surface of the rotating shaft 514 is fixedly connected to a hook rod 515. The upper end of the pillar 501 is fixedly connected to a fixed rod 516. By hooking the hook rod 515 on the fixed rod 516, the motor 502 can be kept away from the mold for subsequent pouring operations.

[0026] The surface of the pillar 501 is rotatably connected to a rotating rod 518, and the surface of the rotating rod 518 is fixedly connected to a rotating hook piece 517. The rotating hook piece 517 can hook the rotating shaft 514 to prevent the motor 502 from jumping when rotating and causing the engaging block 511 to disengage from the groove. The arc surface of the rotating rod 518 is fixedly connected to an elastic piece 520, and the surface of the pillar 501 is fixedly connected to a limiting column 519. The elastic piece 520 is inserted into the interior of the limiting column 519, and the elastic piece 520 can drive the two rotating hook pieces 517 to merge, so as to hook the rotating shaft 514. The top of the movable hook piece 517 is fixedly connected to a guide piece 521, and the top of the cleaning splicing plate 507 is internally slidably connected to a moving block 522, and the internal rotation of the moving block 522 is connected to a long shaft 523, and the surface of the long shaft 523 is fixedly connected to a cutting piece 508, which can clean smaller and thinner aluminum chips. The surface of the long shaft 523 is fixedly connected to a plurality of springs 524, and the plurality of springs 524 are all fixedly connected to the cleaning splicing plate 507. The spring 524 can push the cutting piece 508 out of the cleaning splicing plate 507 while making the cutting piece 508 stick to the inner wall of the movable mold 3.

[0027] By adopting the above technical solution, after the casting of the aluminum shell is completed and the aluminum shell is removed, the rocker 513 is lifted and rotated to separate the hook rod 515 from the surface of the fixed rod 516. At this time, the motor 502 can move downward until the fitting block 511 is inserted into the groove on the surface of the rotating block 504. Then, the fitting block 511 is driven to rotate by the motor 502 while the rotating block 504 is rotated, which can drive the inner mold 409 to rotate. In the process of the motor 502 inserting into the rotating block 504, the weight of the motor 502 can make the push rod 505 move downward, and the inner mold 409 can be rotated. The lower end of the push rod 505 squeezes the inclined surface of the extrusion plate 506, so that the cleaning splicing plate 507 can be extended from the inner mold 409 and attached to the inner wall of the movable mold 3. At this time, the tension spring 525 is in a stretched state. In this way, when the motor 502 drives the inner mold 409 to rotate, the cleaning splicing plate 507 can also be synchronously driven to slide on the inner wall of the movable mold 3. The cleaning splicing plate 507 can be used to collide with the residual aluminum slag, thereby cleaning the aluminum slag on the internal arc surface of the movable mold 3 and reducing the intensity of subsequent cleaning operations.

[0028] Since the spring 524 is in a compressed state, when the cleaning splicing plate 507 extends from the inside of the inner mold 409, the inclined spring 524 can push the long axis 523 to rotate while moving the movable block 522 to the left, which can drive the cutting piece 508 to extend from the cleaning splicing plate 507 while making the cutting piece 508 stick to the inner wall of the movable mold 3, and can drive the cutting piece 508 to slide on the inner wall of the movable mold 3, thereby compensating for the defect that the arc surface angle of the cleaning splicing plate 507 is different from the angle of the inner arc surface of the movable mold 3 and cannot be completely fitted, resulting in the smaller and thinner aluminum chips cannot be cleaned due to impact.

[0029] As the motor 502 moves downward, the rotating shaft 514 will also move downward synchronously until the rotating shaft 514 squeezes the two guide plates 521 apart. At this time, the elastic plate 520 bends. After the fitting block 511 enters the groove, the elastic plate 520 straightens again and drives the two rotating hook plates 517 to merge, which can hook the rotating shaft 514 to prevent the motor 502 from jumping when rotating and causing the fitting block 511 to escape from the groove; after completing the cleaning operation, the two rotating hook plates 517 are pried apart, and then the rocker 513 is lifted to move the motor 502 to the end of the pillar 501, and then the rotating shaft 514 is rotated and the rocker 513 is released, and the hook rod 515 is hooked on the fixed rod 516, so that the motor 502 can be moved away from the mold for subsequent pouring operations.

[0030] Usage: First, pour molten aluminum into the pouring hopper 510. The aluminum will flow into the gap between the movable mold 3 and the inner mold 409. Wait for the aluminum to cool and solidify. Next, the hydraulic rod 401 is used to pull the peeling splicing plate 403 to move leftward, so that the plurality of peeling splicing plates 403 are separated from the surface of the aluminum shell; Then, the hydraulic rod 401 continues to pull the connecting frame 404 to move leftward, and can pull the movable mold 3 to move leftward, thereby realizing the separation of the movable mold 3 and the fixed mold 2, and completing the casting of the aluminum shell; Then, the rocker 513 is lifted and rotated, the motor 502 can move downward, and the engaging block 511 is inserted into the groove on the surface of the rotating block 504; Finally, the motor 502 drives the cleaning splicing plate 507 and the cutting blade 508 to slide on the inner wall of the movable mold 3, so as to clean the aluminum slag on the inner arc surface of the movable mold 3.

[0031] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
