Description

Technical Field

[0001] This invention relates to the field of centrifugal casting machine technology, specifically to a tiltable vertical and horizontal multifunctional centrifugal casting machine. Background Technology

[0002] Centrifugal casting machines are specialized machines that precisely pour molten metal into a rotating mold, using powerful centrifugal force to fully fill and solidify the molten metal, ultimately creating high-quality castings. Based on the different rotating shafts of the mold, they are mainly divided into three categories: horizontal, vertical, and inclined. Among these models, horizontal centrifugal casting machines are the most widely used.

[0003] For example, patent CN109590443B discloses a horizontal centrifugal casting machine, including a base and a feeding trough set on the base; it also includes a horizontally arranged mold cylinder, support rollers, a grinding unit, a motor, and a controller; the controller is used to control the operation of the centrifugal casting machine; the mold cylinder is supported by two pairs of support rollers arranged in pairs and rotated by the support rollers; the output shaft of the motor is connected to the support rollers, and the motor is used to drive the support rollers to rotate; the grinding unit is set on the mold cylinder, and the grinding unit is used to grind and polish the tubular casting formed inside the mold cylinder; through the cooperation between the grinding disc, cylinder 1, cylinder 2, and an annular water tank, the grinding disc is able to grind the inner wall of the tubular casting back and forth, improving the flatness of the inner wall of the tubular casting, reducing the time required for the grinding process, improving production efficiency, and at the same time reducing the stress of the tubular casting itself and increasing the strength of the tubular casting.

[0004] The horizontal centrifugal casting machine in the aforementioned patent still has certain shortcomings:

[0005] Currently, centrifugal casting manufacturers, in order to reduce costs, generally adopt a strategy of installing only one type of centrifugal casting machine: horizontal or vertical. However, both types of casting machines have limitations, only capable of producing specific types of products, and cannot be flexibly converted to adapt to diverse production needs. If a manufacturer needs to produce different types of centrifugal castings, and the installed casting machine is incompatible, it must purchase the corresponding equipment. This singular equipment configuration not only increases the manufacturer's operational burden but also greatly limits the flexibility of its production capacity, making it difficult for manufacturers to meet the increasingly diverse product demands of the market, thus restricting their market competitiveness to some extent. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a tiltable multi-functional centrifugal casting machine that can be switched between horizontal and vertical modes, enabling multiple uses in one machine and reducing investment costs.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a tiltable vertical / horizontal multi-functional centrifugal casting machine, comprising a centrifugal casting machine body, a flange fixedly connected to the end of the centrifugal casting machine body, a mold fixedly connected to the flange, a base provided at the bottom of the centrifugal casting machine body, a set of symmetrically arranged support frames fixedly connected to the top of the base, the centrifugal casting machine body being rotatably connected to the upper end of the support frames, a mounting plate fixedly connected to one side of one support frame, a motor fixedly connected to one side of the mounting plate, the output end of the motor being fixedly connected to the side wall of the centrifugal casting machine body, an auxiliary positioning component rotatably connected to one side of the flange, a support component rotatably connected to the upper end of the support frame, a feeding component slidably connected to the end of the support component away from the support frame, and a limit component connected to one side of the support frame.

[0008] Furthermore, the auxiliary positioning component includes a support cylinder and a support block. The outer wall of the flange is provided with an annular groove, and the support block is slidably connected inside the annular groove. A set of symmetrically arranged hinge blocks are fixedly connected to one end of the base near the mold. A support cylinder is provided between the hinge blocks and rotatably connected to them. The output end of the support cylinder is hinged to the support block.

[0009] Furthermore, the support assembly includes a rotating ring, a fixed block, an insert block, a fixing bolt, and a support plate. The top of the support frame has a rotating groove, and the rotating ring is rotatably connected inside the rotating groove. The fixed block is fixedly connected to the side of the rotating ring near the mold. The fixed block has a slot at the end away from the rotating ring, and the insert block is slidably connected inside the slot. The support plate is fixedly connected to the end of the insert block away from the fixed block. The fixing bolt is slidably connected to the middle position of the insert block, and the fixing bolt is threadedly connected to the fixed block.

[0010] Furthermore, the feeding assembly includes a guide pipe, a slider, and a guide rail. The guide pipe is located at the middle position of the end of the mold away from the main body of the centrifugal casting machine. The guide rail is fixedly connected to the end of the support plate away from the fixed block. A slider is slidably connected to the guide rail, and one side of the slider is fixedly connected to the guide pipe.

[0011] Furthermore, a set of symmetrically arranged positioning blocks are fixedly connected to one end of the guide tube away from the mold, and a guide hopper is provided between the two positioning blocks. A connecting rod is rotatably connected to the middle position of the positioning blocks, and the end of the connecting rod near the positioning block is fixedly connected to the guide hopper.

[0012] Furthermore, a sliding frame is rotatably connected to the end of the connecting rod away from the positioning block. An adjusting gear is fixedly connected to the connecting rod inside the sliding frame. A toothed block is fixedly connected to the bottom of the guide rail located at the upper end of the support plate. The toothed block meshes with the adjusting gear.

[0013] Furthermore, the limiting assembly includes a positioning rod, a reset elastic element, a traction rope, a take-up roller, a transmission gear, and a drive gear. The lower end of the support plate has a slot, through which the traction rope passes. One end of the traction rope is fixedly connected to the slider, and the other end is fixedly connected to the take-up roller. A transmission gear is fixedly connected to the side of the take-up roller near the support frame. The take-up roller and the transmission gear are rotatably connected to the support frame. Drive gears are fixedly connected to both sides of the centrifugal casting machine body, and the drive gear meshes with the transmission gear. A positioning rod that is slidably connected to the support plate is fixedly connected to the side of the slider near the fixed block. A reset elastic element is sleeved on the outside of the positioning rod. One end of the reset elastic element is fixedly connected to the slider, and the other end is fixedly connected to the support plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. When it is necessary to switch the main body of this tiltable vertical and horizontal multi-functional centrifugal casting machine from horizontal to vertical for operation, it is only necessary to start the motor, which will drive the main body of the centrifugal casting machine to rotate to a vertical position, and then use the auxiliary positioning components for auxiliary fixation.

[0016] 2. In this type of tiltable vertical and horizontal multi-functional centrifugal casting machine, during the rotation process of the centrifugal casting machine body changing from horizontal to vertical, the limiting component will pull and drag the feeding component, so that the end of the feeding component can penetrate into the mold, thereby facilitating the feeding of materials when the centrifugal casting machine body is in a vertical state.

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] Please see Figures 1 to 11 A tiltable vertical / horizontal multi-functional centrifugal casting machine includes a centrifugal casting machine body 1. A flange 8 is fixedly connected to the end of the centrifugal casting machine body 1, and a mold 10 is fixedly connected to the flange 8. A base 2 is provided at the bottom of the centrifugal casting machine body 1, and a set of symmetrically arranged support frames 3 are fixedly connected to the top of the base 2. The centrifugal casting machine body 1 is rotatably connected to the upper end of the support frames 3. A mounting plate 34 is fixedly connected to one side of one of the support frames 3, and a motor 33 is fixedly connected to one side of the mounting plate 34. The output end of the motor 33 is fixedly connected to the side wall of the centrifugal casting machine body 1. An auxiliary positioning component is rotatably connected to one side of the flange 8. A support component is rotatably connected to the upper end of the support frame 3. A feeding component is slidably connected to the end of the support component away from the support frame 3. A limit component is connected to one side of the support frame 3.

[0031] The tiltable vertical-horizontal multi-functional centrifugal casting machine of this invention allows for easy switching between horizontal and vertical operation of the main body 1. Simply start the motor 33, which rotates the main body 1 to a vertical position (90°). During this adjustment, an auxiliary positioning component provides additional support. After adjustment, the auxiliary positioning component also secures the flange 8 to prevent shaking of the main body 1. Conversely, when switching back to horizontal operation, simply start the motor 33 and rotate it 90° in the opposite direction. This structure allows the main body 1 to switch freely between horizontal and vertical centrifugal casting, achieving multi-purpose functionality, reducing the number of centrifugal casting machines required, thus reducing the floor space and investment costs. Furthermore, the structure of the main body 1 in this invention is similar to that of a horizontal centrifugal casting machine disclosed in patent CN109590443B, and therefore will not be elaborated upon here.

[0032] As a preferred technical solution of the present invention, the auxiliary positioning component includes a support cylinder 6 and a support block 7. An annular groove 9 is provided on the outer wall of the flange 8. The support block 7 is slidably connected inside the annular groove 9. A set of symmetrically arranged hinge blocks 5 are fixedly connected to one end of the top of the base 2 near the mold 10. A support cylinder 6 is provided between the hinge blocks 5 and rotatably connected to them. The output end of the support cylinder 6 is hinged to the support block 7.

[0033] Specifically, during the rotation of motor 33, support cylinder 6 moves synchronously, providing support for the centrifugal casting machine body 1 and preventing excessive force on the motor bearings of motor 33, which could damage the motor. Simultaneously, after the centrifugal casting machine body 1 completes its state switching, support cylinder 6 also provides support and positioning, making the centrifugal casting machine body 1 more stable and less prone to shaking, thus preventing vibrations from damaging the equipment during operation. Furthermore, support cylinder 6 is supplied with air from an external air source (such as an air pump). In this invention, both motor 33 and support cylinder 6 are controlled by an external control system (such as a control cabinet or control panel). Since these are existing products or technologies, they will not be elaborated upon further here.

[0034] As a preferred embodiment of the present invention, the support assembly includes a rotating ring 13, a fixing block 14, an insert block 16, a fixing bolt 17, and a support plate 18. The top of the support frame 3 is provided with a rotating groove 4, and the rotating ring 13 is rotatably connected inside the rotating groove 4. The fixing block 14 is fixedly connected to the side of the rotating ring 13 near the mold 10. The end of the fixing block 14 away from the rotating ring 13 is provided with a slot 15. The insert block 16 is slidably connected inside the slot 15. The end of the insert block 16 away from the fixing block 14 is fixedly connected to the support plate 18. The fixing bolt 17 is slidably connected to the middle position of the insert block 16. The fixing bolt 17 is threadedly connected to the fixing block 14.

[0035] As a preferred technical solution of the present invention, the feeding assembly includes a guide pipe 11, a slider 21 and a guide rail 19. The guide pipe 11 is provided at the middle position of the end of the mold 10 away from the centrifugal casting machine body 1. The guide rail 19 is fixedly connected to the end of the support plate 18 away from the fixed block 14. The slider 21 is slidably connected on the guide rail 19. One side of the slider 21 is fixedly connected to the guide pipe 11.

[0036] Specifically, after the mold 10 is installed on the flange 8, a support component of appropriate size can be selected according to the size of the mold 10. Then, the insert block 16 at the end of the support plate 18 is inserted into the slot 15 and fixed with the fixing bolt 17. Then, the slider 21 is pushed to adjust the position of the end of the guide pipe 11 inside the mold 10. (If the centrifugal casting machine body 1 is in a horizontal state, the end of the guide pipe 11 only needs to be inside the mold 10. However, if the centrifugal casting machine body 1 is in a vertical state, the end of the guide pipe 11 needs to be close to the bottom of the mold 10 to prevent material splashing.)

[0037] As a preferred technical solution of the present invention, a set of symmetrically arranged positioning blocks 32 are fixedly connected to one end of the guide tube 11 away from the mold 10, and a guide hopper 12 is provided between the two positioning blocks 32. A connecting rod 31 is rotatably connected to the middle position of the positioning blocks 32, and one end of the connecting rod 31 near the positioning block 32 is fixedly connected to the guide hopper 12.

[0038] As a preferred technical solution of the present invention, the end of the connecting rod 31 away from the positioning block 32 is rotatably connected to the sliding frame 24. The sliding frame 24 is provided with an adjusting gear 25 fixedly connected to the connecting rod 31. The bottom of the guide rail 19 located at the upper end of the support plate 18 is fixedly connected to the tooth block 20, which meshes with the adjusting gear 25.

[0039] As a preferred embodiment of the present invention, the limiting assembly includes a positioning rod 22, a reset elastic element 23, a traction rope 27, a take-up roller 28, a transmission gear 29, and a drive gear 30. The lower end of the support plate 18 is provided with a slot 26, and the traction rope 27 is inserted through the slot 26. One end of the traction rope 27 is fixedly connected to the slider 21, and the other end of the traction rope 27 is fixedly connected to the take-up roller 28. The transmission gear 29 is fixedly connected to the side of the take-up roller 28 near the support frame 3. The take-up roller 28 and the transmission gear 29 are rotatably connected to the support frame 3. The drive gear 30 is fixedly connected to both sides of the centrifugal casting machine body 1. The drive gear 30 meshes with the transmission gear 29. The positioning rod 22, which is slidably connected to the support plate 18, is fixedly connected to the side of the slider 21 near the fixed block 14. The reset elastic element 23 is sleeved on the outside of the positioning rod 22. One end of the reset elastic element 23 is fixedly connected to the slider 21, and the other end of the reset elastic element 23 is fixedly connected to the support plate 18.

[0040] Specifically, when the centrifugal casting machine body 1 is adjusted from horizontal to vertical, the mold 10 pushes the guide pipe 11, which in turn drives the support plate 18 to rotate. As the support plate 18 rotates with the centrifugal casting machine body 1, the drive gear 30, which is fixed to the centrifugal casting machine body 1, drives the transmission gear 29, which meshes with it, to rotate. Since the diameter of the transmission gear 29 is much smaller than the diameter of the drive gear 30, even if the drive gear 30 (rotating clockwise) only rotates 90°, the transmission gear 29 will still rotate multiple times. During the rotation of the transmission gear 29, the take-up roller 28, which is fixed to the transmission gear 29, will also rotate synchronously (at this time, the take-up roller 28 rotates counterclockwise), thereby winding up the traction rope 27. When the traction rope 27 is wound up, it will pull the slider 21 to slide towards the support frame 3, so that the end of the guide pipe 11 that discharges material goes deep into the mold 10.

[0041] Meanwhile, as the guide pipe 11 moves toward the support frame 3, the positioning block 32 fixed to the guide pipe 11 pulls the guide hopper 12 to move toward the support frame 3 together. Both sides of the guide hopper 12 are fixed with connecting rods 31, and the ends of the connecting rods 31 are fixed with adjusting gears 25. Therefore, the adjusting gears 25 will move toward the support frame 3 together with the guide hopper 12. Since the adjusting gears 25 mesh with the toothed block 20, they will also rotate synchronously when they move (the direction of rotation is counterclockwise). In this way, the adjusting gears 25 will rotate with the guide hopper 12, so that the opening of the guide hopper 12 always faces upward, which is convenient for subsequent material feeding.

[0042] Furthermore, when the centrifugal casting machine body 1 switches from a vertical state to a horizontal state, the drive gear 30 will rotate in the opposite direction (i.e., counterclockwise). The transmission gear 29, which meshes with the drive gear 30, will drive the take-up roller 28 to rotate clockwise, thereby releasing the traction rope 27. The slider 21 will lose the restriction of the traction rope 27, and the reset elastic element 23 will push the slider 21 back to its original position. The slider 21 will then take the guide pipe 11 and the guide hopper 12 back to their original positions. During the sliding process of the slider 21, under the downward push of the tooth block 20, the adjusting gear 25 will rotate the guide hopper 12 clockwise, thereby keeping the opening of the guide hopper 12 facing upward, which is convenient for feeding.

[0043] It is worth noting that the centrifugal casting machine body 1 in this invention can also be switched to an inclined state for use. As long as the rotation angle of the motor 33 and the pushing distance of the support cylinder 6 are calculated, the centrifugal casting machine body 1 can be switched from a horizontal (or vertical) state to an inclined state.

[0044] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention.
