Abstract
Description
Technical Field
[0001] This invention relates to the field of casting mold technology, specifically to an intelligent casting mold with a sand mold venting pipe. Background Technology
[0002] Sand casting is a traditional casting process. Its molds are made of molding sand and binders, and it is characterized by high permeability and low cost. The gas sources in sand casting include moisture evaporation from the molding sand, decomposition of the binder, and air entrained by the molten metal. The venting device of the sand casting mold makes full use of the natural permeability of the molding sand, while artificial venting structures (vent holes, vent channels, risers, etc.) compensate for insufficient local venting.
[0003] The vent pipe of a sand casting mold is usually located at the top of the cavity to facilitate the smooth discharge of gas during sand casting. However, the vent holes of existing sand casting molds have the following drawbacks: when foreign matter from the sand mold adheres to the vent pipe, it usually requires manual cleaning periodically, which is not very automated and affects the casting progress. Therefore, there is a need to provide an intelligent casting mold with a sand mold vent pipe to solve the above problems. Summary of the Invention

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.
[0022] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.
[0023] See Figures 1-5 A smart casting mold with a sand-type vent pipe, comprising: A frame 1 is rotatably connected to a mold 2, and an exhaust pipe 10 is installed on the mold 2; The casting component 3 is rotatably connected to the frame 1. The mold 2 is connected to the casting component 3. The casting component 3 is used to drive the mold 2 to rotate on the frame 1, thereby realizing the precise forming of molten metal by the mold 2. The cleaning component 4 is slidably connected inside the exhaust pipe 10, and its end is connected to the casting component 3 for cooperating with the casting component 3 to realize the reciprocating sliding of the cleaning component 4 inside the exhaust pipe 10. The pressurizing component 5 is rotatably connected inside the mold 2 and communicates with the exhaust pipe 10, and is used to extract air from the mold 2 through the exhaust pipe 10. The drive component 6 is rotatably connected inside the mold 2. One end is connected to the cleaning component 4, and the other end is connected to the pressurizing component 5. It is used to rotate in cooperation with the cleaning component 4, thereby enabling the pressurizing component 5 to discharge the air inside the mold 2.
[0024] In one embodiment of the present invention, as shown in Figure 2, the mold 2 includes an upper mold 21 and a lower mold 22, and the upper mold 21 and the lower mold 22 are integrally rotatably connected inside the frame 1. A tilting gate 23 is fixed to the side of the lower mold 22. Reinforcing ribs 24 are fixed to the side edges of the upper mold 21 and the lower mold 22, and C-shaped buckles 25 are slidably connected to the surface of the reinforcing ribs 24.
[0025] When connecting the upper mold 21 and the lower mold 22, the upper mold 21 is placed on the surface of the lower mold 22, and the C-shaped buckle 25 is slid so that the C-shaped buckle 25 slides to the surface of the two sets of reinforcing ribs 24, so that the upper mold 21 and the lower mold 22 are fixed under the action of the C-shaped buckle 25.
[0026] In this embodiment, during the casting of the metal casting, the molten metal is poured into the tilting gate 23. At this time, a portion of the molten metal will enter the cavity inside the upper mold 21 and the lower mold 22 through the sprue. The casting assembly 3 drives the upper mold 21 and the lower mold 22 to rotate in the frame 1. At this time, under the action of gravity, the molten metal flows into the cavity inside the upper mold 21 and the lower mold 22 through the sprue, filling the entire cavity.
[0027] In one embodiment of the present invention, such as Figure 1 As shown, the casting component 3 includes: The tilting frame 31 is fixed to the lower side of the lower mold 22, and the surface is provided with a tilting frame groove 311; Support 33 is connected to the side of frame 1; The rotating shaft 32 is fixed on the tilting frame 31, and its two ends are rotatably connected to the support frame 33; The support groove 34 is opened on the side of the two sets of supports 33, and the internal slidably connected is a U-shaped frame 37; A through slot 35 is formed on the support slot 34; The sliding column 36 is fixed at both ends of the C-shaped frame 37. One end of the sliding column 36 is slidably connected inside the inclined frame groove 311, and the other end is slidably connected inside the through groove 35. The drive cylinder 38 is fixed on the frame 1, and the output end of the drive cylinder 38 is connected to the side of the shaped frame 37.
[0028] In this embodiment, during the pouring of the metal casting, after the molten metal is poured into the tilting gate 23, the drive cylinder 38 is activated, causing the drive cylinder 38 to pull the mold frame 37 to slide within the support groove 34 (towards the drive cylinder 38). When the mold frame 37 slides, it can drive the sliding column 36 to slide synchronously within the through groove 35. Therefore, the tilting frame 31 will drive the rotating shaft 32 to rotate clockwise within the support 33 under the action of the tilting frame groove 311 and the sliding column 36. The rotating shaft 32 will drive the lower mold 22 and the upper mold 21 to rotate as a whole through the tilting frame 31. When the lower mold 22 rotates, it will drive the tilting gate 23 to rotate synchronously until the upper mold 21 and the lower mold 22 are both rotated to a vertical state. This allows the molten metal in the tilting gate 23 to flow into the cavity inside the upper mold 21 and the lower mold 22 through the sprue under the action of gravity, thus completing the casting.
[0029] After the casting has cooled and solidified, the drive cylinder 38 is first activated, causing the molded frame 37 to slide in the opposite direction within the support groove 34. At this time, in the opposite direction to the above process, the rotating shaft 32 will drive the lower mold 22 and the upper mold 21 to rotate counterclockwise through the tilting frame 31 until the upper mold 21 and the lower mold 22 are flipped to a horizontal position. Figure 2 (State). Slide the C-shaped buckles 25 at both ends of the upper mold 21 so that the C-shaped buckles 25 are separated from the surface of the reinforcing rib 24, and clean the molding sand out of the mold by connecting the upper mold 21 and the lower mold 22.
[0030] In one embodiment of the present invention, such as Figure 4 As shown, the cleaning component 4 includes: The rotating cylinder 41 is rotatably connected inside the upper mold 21. The surface is provided with a first inclined groove 411 and a second inclined groove 412. The first inclined groove 411 and the second inclined groove 412 are in opposite directions and are connected end to end. The first gear 42 is fixed to the end of the rotating cylinder 41; An arc-shaped frame 43 is connected to a support frame 33, and an arc-shaped rack 431 is provided on the inner side. The arc-shaped rack 431 and the first gear 42 are meshed and connected. A vertical slot 45 is provided on the side of the exhaust pipe 10; The lifting frame 44 is slidably connected inside the exhaust pipe 10, and a sliding shaft 46 is fixed on the side. One end of the sliding shaft 46 is slidably connected inside the inclined groove 411 or the inclined groove 412, and the other end is slidably connected inside the vertical groove 45.
[0031] In this embodiment, during the filling process of the molten metal, the gas inside the mold 2 can be discharged through the exhaust pipe 10. During the pouring process of the metal casting, when the rotating shaft 32 drives the mold 2 to rotate clockwise through the tilting frame 31, the upper mold 21 will drive the exhaust pipe 10 and the first gear 42 on its upper side to rotate synchronously, so that the first gear 42 rolls on the surface of the arc rack 431. Thus, the first gear 42 will drive the rotating cylinder 41 to rotate inside the upper mold 21 under the action of the arc rack 431. When the rotating cylinder 41 rotates, it can drive the inclined groove 1 411 and inclined groove 2 412 on its surface to rotate synchronously.
[0032] When the rotating cylinder 41 drives the inclined groove 411 and the inclined groove 412 to rotate, the sliding shaft 46 will first drive the lifting frame 44 to slide downward in the exhaust pipe 10 under the action of the inclined groove 411, and at the same time, the sliding shaft 46 will slide downward in the vertical groove 45. When the sliding shaft 46 slides out of the inclined groove 411, the sliding shaft 46 will slide into the inclined groove 412. Then, the sliding shaft 46 will drive the lifting frame 44 to slide upward in the opposite direction in the exhaust pipe 10 under the action of the inclined groove 412, until the sliding shaft 46 slides back into the inclined groove 411. The above working process is repeated, so that the lifting frame 44 slides up and down in the exhaust pipe 10. Thus, the inner wall of the exhaust pipe 10 will be cleaned by the action of the lifting frame 44, so as to avoid the exhaust pipe 10 from being blocked and improve the venting effect of the mold 2 during the casting process.
[0033] In one embodiment of the present invention, such as Figure 4 and Figure 5 As shown, the booster assembly 5 includes: The fixed cylinder 51 is fixed inside the upper mold 21. One side of the fixed cylinder 51 is connected to the vertical groove 45 through the air outlet pipe 511, and the other side is connected to the air inlet frame 512. The air inlet frame 512 is connected to the inside of the upper mold 21 through the air inlet pipe 513. The outlet of the air outlet pipe 511 is parallel to the direction of the exhaust pipe 10 and faces the outside of the mold 2. Driven shaft 52 is eccentrically rotatably connected inside fixed cylinder 51; Rotor 53 is fixed on the surface of driven shaft 52, and one side of the surface is slidably connected to the inner wall of fixed cylinder 51. Two sets of rotor slots 54 are provided on rotor 53. The vane 55 is slidably connected inside a set of rotor slots 54, and its end is slidably connected to the inner wall of the fixed cylinder 51. The second rotor blade 56 is slidably connected inside another set of rotor slots 54, and its end is slidably connected to the inner wall of the fixed cylinder 51.
[0034] In this embodiment, as the rotating cylinder 41 rotates clockwise within the upper mold 21, the rotating cylinder 41 drives the driven shaft 52 to rotate within the fixed cylinder 51 via the drive assembly 6. The driven shaft 52 drives the rotor 53 to rotate within the fixed cylinder 51. Under the action of centrifugal force, the rotor 53 drives the first rotor blade 55 and the second rotor blade 56 within the two sets of rotor slots 54 to slide clockwise on the inner wall of the fixed cylinder 51.
[0035] like Figure 5 As shown, during the clockwise rotation of rotor 53, the space formed by the right side of rotor 53, the right sides of vane 1 55 and vane 2 56, and the inner wall of the right side of fixed cylinder 51 gradually increases. Consequently, the gas in upper mold 21 is drawn into this space sequentially through air inlet pipe 513 and air inlet frame 512. The space formed by the left side of rotor 53, the left side of vane 1 55 and vane 2 56, and the inner wall of the left side of fixed cylinder 51 gradually decreases. Consequently, the gas in this other space enters exhaust pipe 10 through exhaust pipe 511 and is discharged from the end of exhaust pipe 10, thus accelerating the discharge of gas from mold 2.
[0036] In one embodiment of the present invention, such as Figure 5 As shown, the driving component 6 includes: The drive shaft 61 is rotatably connected to the inside of the upper mold 21, and its end is fixedly connected to the rotating cylinder 41. The second gear 62 is mounted on the surface of the drive shaft 61; The third gear 63 is fixed on the surface of the driven shaft 52, and the second gear 62 and the third gear 63 are meshed together.
[0037] In this embodiment, when the rotating cylinder 41 rotates inside the mold 2, it can drive the drive shaft 61 to rotate synchronously inside the upper mold 21. The drive shaft 61 can drive the driven shaft 52 to rotate clockwise inside the fixed cylinder 51 through the second gear 62 and the third gear 63, so that the driven shaft 52 drives the first rotating vane 55 and the second rotating vane 56 to slide on the inner wall of the fixed cylinder 51 through the rotor 53. As a result, the gas inside the mold 2 will be drawn into the fixed cylinder 51. When the ends of the first rotating vane 55 and the second rotating vane 56 rotate to disengage from the exhaust pipe 511, the gas enters the exhaust pipe 10 through the exhaust pipe 511, thereby accelerating the discharge of the gas inside the mold 2. The airflow can also carry out impurities and dust in the exhaust pipe 10.
[0038] The working principle of this invention is as follows: During the pouring process of metal casting, after the molten metal is poured into the tilting gate 23, the drive cylinder 38 is activated, causing the drive cylinder 38 to pull the mold frame 37 to slide in the support groove 34. When the mold frame 37 slides, it can drive the sliding column 36 to slide synchronously in the through groove 35. The tilting frame 31 will drive the rotating shaft 32 to rotate clockwise in the support 33 under the action of the tilting frame groove 311 and the sliding column 36. The rotating shaft 32 will drive the lower mold 22 and the upper mold 21 to rotate as a whole through the tilting frame 31. When the lower mold 22 rotates, it will drive the tilting gate 23 to rotate synchronously until the upper mold 21 and the lower mold 22 are both rotated to a vertical state. Under the action of gravity, the molten metal in the tilting gate 23 flows into the cavity inside the upper mold 21 and the lower mold 22 through the sprue, thus completing the casting.
