Description

Technical Field

[0001] This invention relates to the technical field of gear casting, and more particularly to a blank gear casting and forming equipment. Background Technology

[0002] Gears are commonly used mechanical components that can continuously mesh to transmit motion and power. They have the functions of decelerating, increasing torque, and changing the direction of motion. Among them, casting is a common method in gear production. Molten metal is poured into a gear mold, and after cooling and solidification, the desired gear is formed.

[0003] Currently, complex gear casting generally adopts sand casting, in which casting sand is used to form an outer mold, and then molten metal is poured in and cooled to form the shape. However, before casting with casting sand, it is necessary to manually spread the casting sand first, and then squeeze it with the complex gear model to form the gear forming cavity. Since it is difficult to control the uniformity of the sand spreading by hand, the compactness of the casting sand will be affected when it is spread and distributed. Some parts are over-compacted, while the casting sand around some thin-walled or slender parts is not compacted enough, resulting in casting filling defects and dimensional deviations, which reduces the quality and pass rate of complex gears. Summary of the Invention

[0004] In view of the problems existing in the above-mentioned blank gear casting and forming equipment, the present invention is proposed.

[0005] Therefore, the present invention provides a blank gear casting molding equipment, the purpose of which is to solve the problem that manual sand spreading is difficult to control evenly, which affects the compactness of the casting sand and leads to casting filling defects and dimensional deviations.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: including an operating console; The molding unit includes a vibration assembly disposed on the top of the operating table, a fixed assembly rotatably disposed on the top of the vibration assembly, a compression assembly rotatably disposed inside the fixed assembly, and a mold assembly disposed on the top of the operating table, wherein the compression assembly is rotatably connected to both the fixed assembly and the vibration assembly.

[0009] In a preferred embodiment of the blank gear casting and forming equipment of the present invention, silicone plates are provided at both ends of the extrusion plate.

[0010] In a preferred embodiment of the blank gear casting and forming equipment of the present invention, the vibration component includes a fixed plate disposed on the top of the operating table, a protruding block disposed inside the fixed plate, and a lower guide ring disposed on the top of the fixed plate, and the fixed plate is rotatably connected to the motor.

[0011] In a preferred embodiment of the blank gear casting and forming equipment of the present invention, the fixed component includes a buffer member slidably disposed inside the lower guide ring, an upper guide ring slidably disposed at the other end of the buffer member, a forming member disposed at the top of the upper guide ring, and a movable wheel disposed at the bottom of the forming member, wherein the movable wheel is slidably connected to the protrusion block.

[0012] As a preferred embodiment of the blank gear casting and forming equipment of the present invention, the forming part is provided with a bottom plate inside, and the bottom plate is slidably connected to the moving rod and rotatably connected to the first rotary guide and the second rotary guide.

[0013] As a preferred embodiment of the blank gear casting and forming equipment of the present invention, the mold assembly includes an L-shaped support member disposed on the top of the operating table, a fixing member disposed on the other end of the L-shaped support member, a hydraulic rod disposed on the top of the fixing member, and a connecting member disposed on the output end of the hydraulic rod.

[0016] The beneficial effects of this invention are as follows: By integrating the mold assembly, compression assembly, and vibration assembly into a three-in-one coordinated operation, gradient compaction of the casting sand is achieved. The mold assembly and compression assembly first compact the casting sand layer by layer along the surface of the gear mold through bidirectional pressure. Then, the vibration assembly provides micro-vibration, causing the casting sand to undergo secondary flow and rearrangement under the coupled action of extrusion vibration. This eliminates local over-tight areas and automatically fills weak areas around complex structures such as thin walls and fine ribs. As a result, a casting sand model with uniform compaction and consistent permeability is obtained throughout the entire cavity. Furthermore, the continuous rotation of the compression assembly further evenly transmits vibration energy to the interior of the casting sand, forming a gradient structure with a hard surface and a tough inner layer. This ensures a smooth cavity surface and accurate dimensions while maintaining appropriate flexibility in the inner layer, reducing the probability of thermal cracking, porosity, and filling defects. After discharge, the compression assembly rotates in the opposite direction and vibrates synchronously, causing the casting sand to disintegrate and the finished product to fall off. Combined with the cyclic mode of adding sand once and pouring multiple times, the casting accuracy and casting quality are improved. Attached Figure Description

Detailed Implementation

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Example 1, referring to Figure 1 - Figure 4 The first embodiment of the present invention provides a blank gear casting and forming equipment, which includes: an operating table 100, a forming unit 200, and a discharge unit 300.

[0031] The molding unit 200 includes a vibration component 203 disposed on the top of the operating table 100, a fixing component 202 rotatably disposed on the top of the vibration component 203, a compression component 201 rotatably disposed inside the fixing component 202, and a mold component 204 disposed on the top of the operating table 100, wherein the compression component 201 is rotatably connected to both the fixing component 202 and the vibration component 203. The discharge unit 300 includes a discharge component 301 disposed inside the operating table 100, and the discharge component 301 cooperates with the mold component 204. Before gear casting, the operator first puts casting sand into the fixed component 202, and then the mold component 204 begins to move downwards until it reaches the top of the fixed component 202. At this point, the gear mold 2045 inside the mold component 204 is in contact with the bottom of the fixed component 202. Simultaneously, the connecting piece 2044 in the mold component 204 compresses the casting sand inside the fixed component 202, causing the casting sand to begin to be firmly formed according to the shape of the gear. At the same time, the compression component 201 begins to drive, and... After the compression component 201 and the mold component 204 work together to fully compress the casting sand inside the fixed component 202, the compression component 201 continues to rotate, causing the fixed component 202 to begin rotating along the vibration component 203. With the cooperation of the vibration component 203, the fixed component 202 begins to vibrate, causing the casting sand inside the fixed component 202 to vibrate under the continuous compression of the compression component 201. This ensures that the casting sand can completely and tightly adhere to the gear mold, preventing the compaction of the casting sand from being affected when it is spread out, which could lead to over-compactment in some parts and insufficient compaction around some thin-walled or slender parts, resulting in casting filling defects and dimensional deviations.

[0032] After the casting sand inside the fixed component 202 forms the gear mold, the compression component 201 stops rotating, and the mold component 204 begins to move upward in a small range, causing the casting sand inside the fixed component 202 to form a mold cavity. Then, the molten metal solution through the discharge component 301 is transported through the mold component 204 into the casting sand inside the fixed component 202 to begin casting. After casting is completed and cooled, the mold component 204 moves upward, and the compression component 201 rotates in the opposite direction, causing the compression component 201 to release the pressure on the casting sand and move to both sides. At the same time, the vibration component 203 causes the fixed component 202 to vibrate again, thereby causing the casting sand inside the fixed component 202 to be vibrated and scattered. The workpiece formed inside the casting sand is taken out for the next casting, allowing for multiple castings with a single sand addition.

[0033] During operation, before gear casting, the operator first puts casting sand into the fixed component 202. Then, the mold component 204 begins to move downwards until it reaches the top of the fixed component 202. At this point, the gear mold 2045 inside the mold component 204 contacts the bottom of the fixed component 202. Simultaneously, the connector 2044 in the mold component 204 compresses the casting sand inside the fixed component 202, causing it to begin to conform to the shape of the gear. At the same time, the compression component 201 is activated, squeezing the casting sand inside the fixed component 202 towards the center. Combined with the squeezing action of the mold component 204, this ensures that the casting sand inside the fixed component 202 completely conforms to the gear mold. Externally, after the compression component 201 and the mold component 204 work together to completely compress the casting sand inside the fixed component 202, the compression component 201 continues to rotate, causing the fixed component 202 to begin rotating along the vibration component 203. With the cooperation of the vibration component 203, the fixed component 202 begins to vibrate, causing the casting sand inside the fixed component 202 to vibrate under the continuous compression of the compression component 201. This ensures that the casting sand can completely and tightly adhere to the gear mold, preventing the compactness of the casting sand from being affected when it is spread out, which could lead to over-compactment in some parts and insufficient compaction around some thin-walled or slender parts, resulting in casting filling defects and dimensional deviations.

[0034] After the casting sand inside the fixed component 202 forms the gear mold, the compression component 201 stops rotating, and the mold component 204 begins to move upward in a small range, causing the casting sand inside the fixed component 202 to form a mold cavity. Then, the molten metal solution through the discharge component 301 is transported through the mold component 204 into the casting sand inside the fixed component 202 to begin casting. After casting is completed and cooled, the mold component 204 moves upward, and the compression component 201 rotates in the opposite direction, causing the compression component 201 to release the pressure on the casting sand and move to both sides. At the same time, the vibration component 203 causes the fixed component 202 to vibrate again, thereby causing the casting sand inside the fixed component 202 to be vibrated and scattered. The workpiece formed inside the casting sand is taken out for the next casting, which allows for multiple castings with one sand addition, improving casting accuracy and casting quality.

[0035] Example 2, refer to Figure 1 - Figure 8This is the second embodiment of the present invention, which differs from the first embodiment in that: the fixing component 202 includes a buffer 2025 slidably disposed inside the lower guide ring 2033, an upper guide ring 2024 slidably disposed at the other end of the buffer 2025, a molding component 2021 disposed on the top of the upper guide ring 2024, and a moving wheel 2023 disposed at the bottom of the molding component 2021, wherein the moving wheel 2023 is slidably connected to the protrusion 2032. A base plate 2022 is disposed inside the molding component 2021, and the base plate 2022 is slidably connected to the moving rod 2015 and rotatably connected to the first rotary guide component 2012 and the second rotary guide component 2013. During gear casting, casting sand is poured into the interior of the molding component 2021, and then the mold assembly 204 moves downward, moving the gear model. After reaching the top of the base plate 2022 inside the molded part 2021, the motor 2011 starts to work, causing the first rotary guide 2012 and the second rotary guide 2013 to rotate inside the base plate 2022. While the first rotary guide 2012 and the second rotary guide 2013 are rotating, the moving shaft 2014 also moves inside the first rotary guide 2012 and the second rotary guide 2013, causing the moving rod 2015 to move into the base plate 2022. At the same time, the shrinking rod 2017 and the extrusion plate 2018 at the other end of the moving rod 2015 begin to extrude the casting sand in the middle of the base plate 2022, extruding the casting sand to the outside of the mold at the bottom of the mold assembly 204. With the cooperation of the mold assembly 204, the casting sand begins to form a casting cavity around the outside of the mold.

[0036] Compared to Embodiment 1, the compression assembly 201 further includes a motor 2011 disposed inside the operating table 100, a first rotary guide 2012 disposed at the output end of the motor 2011, a moving shaft 2014 slidably disposed inside the first rotary guide 2012, a moving rod 2015 disposed on the outer diameter of the moving shaft 2014, a retraction rod 2017 slidably disposed on the other end of the moving rod 2015, and a pressing plate 2018 disposed on the other end of the retraction rod 2017. The moving rod 2015 is slidably connected to the fixing assembly 202. A second rotary guide 2013 is disposed on the outer diameter of the output of the motor 2011, and the interior of the second rotary guide 2013 is slidably connected to the moving shaft 2014. The second rotary guide 2013 is fixedly connected to the first rotary guide 2012. A first return spring 2016 is disposed inside the moving rod 2015, and the other end of the first return spring 2016 is connected to the retraction rod 2017. The two ends of the pressing plate 2018 are... A silicone plate 2019 is provided at the end. When the extrusion plate 2018 extrudes the casting sand inside the molded part 2021, the silicone plates 2019 on both sides of the extrusion plate 2018 also stick together to prevent the casting sand from being squeezed out. At the same time, the return spring 2016 inside the shrinkage rod 2017 also buffers the extrusion process of the extrusion plate 2018, ensuring that the casting sand inside the molded part 2021 can be completely adhered to the outside of the mold at the bottom of the mold assembly 204. This allows the casting sand to be compacted layer by layer along the surface of the gear mold to eliminate local over-tight areas, and automatically fills the weak areas around complex structures such as thin walls and fine ribs. As a result, a casting sand model with uniform compactness and consistent air permeability is obtained throughout the cavity. Furthermore, the continuous rotation of the compression assembly 201 further transmits the vibration energy evenly to the interior of the casting sand, making the casting sand form a gradient structure with a hard surface and a tough inner layer. This ensures that the cavity surface is smooth and the dimensions are accurate, while also maintaining appropriate yielding in the inner layer, reducing the probability of thermal cracking, porosity, and filling defects.

[0037] During use, when casting gears, casting sand is introduced into the molded part 2021. Then, the mold assembly 204 moves downward, moving the gear model to the top of the base plate 2022 inside the molded part 2021. The motor 2011 then starts working, causing the first rotary guide 2012 and the second rotary guide 2013 to rotate inside the base plate 2022. While the first rotary guide 2012 and the second rotary guide 2013 are rotating, the moving shaft 2014 also moves inside the first rotary guide 2012 and the second rotary guide 2013, causing the moving rod 2015 to move into the base plate 2022. At the same time, the shrinking rod 2017 and the extrusion plate 2018 at the other end of the moving rod 2015 begin to extrude the casting sand in the middle of the base plate 2022, extruding the casting sand to the outside of the mold at the bottom of the mold assembly 204. With the cooperation of the mold assembly 204, the casting sand begins to form a casting cavity around the outside of the mold.

[0038] When the extrusion plate 2018 extrudes the casting sand inside the molded part 2021, the silicone plates 2019 on both sides of the extrusion plate 2018 also adhere to each other to prevent the casting sand from being squeezed out. At the same time, the return spring 2016 inside the shrinkage rod 2017 also buffers the extrusion process of the extrusion plate 2018, ensuring that the casting sand inside the molded part 2021 can be completely adhered to the outside of the mold at the bottom of the mold assembly 204. This allows the casting sand to be compacted layer by layer along the surface of the gear mold to eliminate local over-tight areas, and automatically fills the weak areas around complex structures such as thin walls and fine ribs. As a result, a casting sand model with uniform compactness and consistent air permeability is obtained throughout the cavity. Furthermore, the continuous rotation of the compression assembly 201 further transmits the vibration energy evenly to the interior of the casting sand, causing the casting sand to form a gradient structure with a hard surface and a tough inner layer. This ensures that the cavity surface is smooth and the dimensions are accurate, while also maintaining appropriate yielding in the inner layer, reducing the probability of thermal cracking, porosity, and filling defects.

[0039] The remaining structure is the same as that in Example 1.

[0040] Example 3, referring to Figure 1 - Figure 10This is the third embodiment of the present invention, which differs from the second embodiment in that: the vibration assembly 203 includes a fixed plate 2031 disposed on the top of the operating table 100, a protrusion 2032 disposed inside the fixed plate 2031, and a lower guide ring 2033 disposed on the top of the fixed plate 2031, and the fixed plate 2031 is rotatably connected to the motor 2011; the mold assembly 204 includes an L-shaped support member 2041 disposed on the top of the operating table 100, a fixing member 2042 disposed at the other end of the L-shaped support member 2041, and a hydraulic rod 2042 disposed on the top of the fixing member 2042. 43, and a connector 2044 disposed at the output end of the hydraulic rod 2043. A gear mold 2045 is disposed at the bottom of the connector 2044. A discharge port 2046 is disposed inside the gear mold 2045, and the discharge port 2046 passes through and connects to the connector 2044. After the hydraulic rod 2043 moves and the connector 2044 and the gear mold 2045 move downward to the top of the bottom plate 2022, the extrusion plate 2018 and the silicone plate 2019 are driven by the motor 2011 to extrude the casting sand inside the molded part 2021, so that the casting sand is completely adhered to the gear mold 204. Outside of mold 5, and after all the casting sand adheres to the outside of gear mold 2045, motor 2011 continues to drive, causing rotary guide 1 2012 and rotary guide 2 2013 to rotate together with moving rod 2015 and base plate 2022 and molded part 2021. While molded part 2021 rotates, moving wheel 2023 at the bottom of molded part 2021 also begins to rotate on top of fixed plate 2031. Moving wheel 2023 engages with protrusion 2032 to vibrate the entire molded part 2021, causing the casting inside molded part 2021 to... The sand also vibrates, causing the casting sand to undergo secondary flow and rearrangement under the coupled action of extrusion vibration. This eliminates local over-tight areas and automatically fills the weak areas around complex structures such as thin walls and fine ribs. As a result, the casting sand inside the entire molded part 2021 obtains a casting sand model with uniform compactness and consistent air permeability. At the same time, while the molded part 2021 is vibrating, the buffer 2025 inside the upper guide ring 2024 also rotates together with the rotation of the molded part 2021 inside the lower guide ring 2033 and provides vibration buffer for the molded part 2021, ensuring the vibration effect of the molded part 2021.

[0041] Compared to Embodiment 2, the discharge assembly 301 further includes a melting section 3011 disposed inside the operating table 100 and a conveying section 3012 disposed on one side of the melting section 3011. The conveying section 3012 cooperates with the discharge port 2046. After the casting sand inside the molded part 2021 completely adheres to the outside of the gear mold 2045 and forms a casting model, the compression assembly 201 stops working. The hydraulic rod 2043 moves the fixing part 2042 and the gear mold 2045 upwards by a small portion, so that a cavity is formed inside the casting sand. Then, the conveying section 3012 is connected to the top of the discharge port 2046, and the melting sand is discharged through the melting section 3011. The casting liquid is fed into the casting sand inside the molded part 2021 through the discharge port 2046 to begin casting. After casting is completed, the hydraulic rod 2043 moves upward and detaches from the inside of the molded part 2021. At the same time, the compression component 201 also moves in the opposite direction to fix the casting sand inside the molded part 2021. Meanwhile, the molded part 2021 also moves in the opposite direction and vibrates again with the cooperation of the vibration component 203 to disperse the casting sand inside the molded part 2021. The casting product inside can then be directly removed, completing the casting process. The dispersed casting sand can be used for the next casting mold.

[0042] During use, after the hydraulic rod 2043 moves, causing the connecting piece 2044 and the gear mold 2045 to move downwards to the top of the base plate 2022, the motor 2011 drives the extrusion plate 2018 and the silicone plate 2019 to extrude the casting sand inside the molded part 2021, causing the casting sand to adhere completely to the outside of the gear mold 2045. After the casting sand is completely adhered to the outside of the gear mold 2045, the motor 2011 continues to drive, causing the rotating guide 1 2012 and rotating guide 2 2013 to rotate together with the moving rod 2015 and the base plate 2022 and the molded part 2021. While the molded part 2021 is rotating, the moving wheel 2023 at the bottom of the molded part 2021 also begins to move on the top of the fixed plate 2031. The rotating mechanism, with the moving wheel 2023 engaging with the protruding block 2032, begins to vibrate the entire molded part 2021. This causes the casting sand inside the molded part 2021 to vibrate as well, resulting in secondary flow and rearrangement of the casting sand under the coupled action of the extrusion vibration. This eliminates localized overly tight areas and automatically fills weak areas around complex structures such as thin walls and fine ribs. Consequently, the casting sand inside the entire molded part 2021 achieves a uniformly compact and permeable casting sand model. Simultaneously, while the molded part 2021 vibrates, the buffer 2025 inside the upper guide ring 2024 also rotates along with the rotation of the molded part 2021 within the lower guide ring 2033, providing vibration buffer and ensuring the vibration effect of the molded part 2021.

[0043] After the casting sand inside the molded part 2021 completely adheres to the outside of the gear mold 2045 and forms a casting model, the compression assembly 201 stops working. The hydraulic rod 2043 moves upward a small portion, carrying the fixing part 2042 and the gear mold 2045, so that a cavity is formed inside the casting sand. Then, the conveying part 3012 is connected to the top of the discharge port 2046. The molten casting liquid is conveyed through the melting part 3011 to the casting sand inside the molded part 2021 through the discharge port 2046 to start casting. After casting is completed, the hydraulic rod 2043 begins to move upward and detaches from the inside of the molded part 2021. At the same time, the compression assembly 201 also begins to move in the opposite direction to fix the casting sand inside the molded part 2021. Meanwhile, the molded part 2021 also moves in the opposite direction. With the cooperation of the vibration assembly 203, vibration is generated again to disperse the casting sand inside the molded part 2021, so that the casting sand is dispersed. The casting product inside can be directly taken out, completing the casting. At the same time, the dispersed casting sand can be used for the next casting.

[0044] The remaining structure is the same as that in Example 2.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
