DETAILED DESCRIPTION

[0035] The embodiments of the present invention are described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0036] During the die-casting process, various defects will be formed on the airtight castings due to internal gas escape, uneven metal crystal shrinkage, uneven cooling rate control, the influence of impurities in the alloy, defects in molds, equipment, and processes, etc. Defects will lead to the destruction of sealing. For example, local leakage of pressure-bearing parts will cause the medium to enter the pores, causing small hole corrosion, and micropores will destroy the surface flatness and interfere with the surface treatment process. In addition, the force on the tool is not constant during processing, which affects the processing accuracy and reduces the tool life.

[0037] Generally, after die-casting, airtight die-casting parts need to go through an impregnation process to make up for defects. The impregnation liquid is infiltrated into the pores of the workpiece by vacuum pressurization. The impregnation liquid in the pores is polymerized by heating and other means. After polymerization, a stable solid is formed in the pores, thereby achieving a sealing effect.

[0038] In order to improve production efficiency, an automated production line can be set up for automatic impregnation operations. Generally, an automated production line needs to be equipped with an automatic loading station 1, a pretreatment station 2, an impregnation station 3, a centrifugal station 4, a cleaning station 5, and a curing station 6; the impregnation process is a key link. In order to improve the impregnation efficiency in the existing automated production line, a power device is set in the impregnation tank to drive the flow of the impregnation liquid or drive the casting cage to rotate, thereby improving the impregnation efficiency. However, the existing impregnation tank generally only has a filtering device on the connecting pipe with the liquid storage tank. Therefore, the precipitate that appears during the impregnation process will flow with the impregnation liquid. When the precipitate adheres to the surface of the casting, it will prevent the impregnation liquid from penetrating into the pores, thereby affecting the impregnation.

[0039] Therefore, the present application proposes an automated production line for conveying, cleaning and impregnation of airtight castings, which can collect sediments while driving the die-castings to rotate during the impregnation process, thereby preventing the sediments from affecting the impregnation process. At the same time, the filtered sediments can be collected to prevent the sediments from accumulating on the filter screen.

[0040] Specifically, Figure 1As shown, the airtight casting conveying, cleaning and impregnation automatic production line proposed in this application mainly includes automatic feeding station 1, pretreatment station 2, impregnation station 3, centrifugal station 4, cleaning station 5, and curing station 6. Among them, by setting the automatic feeding station 1, the boxed die castings are sequentially conveyed to the pretreatment station 2, impregnation station 3, centrifugal station 4, cleaning station 5, and curing station 6; wherein the pretreatment station 2 includes cleaning to remove oil, dust, impurities, etc. on the surface of the casting to ensure that the impregnant can smoothly penetrate into the inside of the casting. Specifically, solvent cleaning, alkali cleaning, ultrasonic cleaning and other methods can be used. Solvent cleaning uses organic solvents to dissolve grease; alkali cleaning uses the saponification of alkaline solutions to remove grease; ultrasonic cleaning removes dirt on the surface of the casting through the cavitation of ultrasonic waves; drying removes moisture from the surface of the casting to prevent moisture from affecting the performance and impregnation effect of the impregnant during the impregnation process.

[0041] After the pre-treated die casting is sent to the impregnation station 3; first, vacuum the air and dust in the tank and perform dry vacuum; after the dry vacuum is completed, the impregnation liquid enters the vacuum impregnation tank. Continue to vacuum for 5-10 minutes and perform wet vacuum. Expel the air in the impregnant to prevent the impregnant containing gas from penetrating into the microporous defects of the workpiece, and avoid the formation of pores during curing that affect the sealing performance. After the wet vacuum is completed, pressurize and use the pressure difference to make the impregnant enter the pores. Usually pressurize to 0.5Mpa and keep for 5-10 minutes; it can also be kept at normal pressure for 5-10 minutes without pressurization. After the impregnation is completed, centrifuge to remove the residual impregnant on the surface and pores of the parts. Wash the parts to remove the residual impregnant on the surface and pores of the parts. Finally, cure in hot water at 90℃ for 10-20 minutes, and the impregnant in the pores will solidify to form a hard solid.

[0042] like Figure 2-3 As shown, the impregnation station 3 is provided with an impregnation tank, and a cover body 12, a cover opening mechanism, and a sealing mechanism are provided on the top of the impregnation tank; wherein the cover opening mechanism includes an ear seat and a first connecting seat 10 arranged on the side, a first cylinder 9 is rotatably mounted on the ear seat, a second connecting seat 11 is rotatably mounted on the first connecting seat 10, and a cover body 12 is installed on the end of the second connecting seat 11, and the end of the output shaft of the first cylinder 9 is rotatably connected to the second connecting seat 11. When the output shaft of the first cylinder 9 is extended, the second connecting seat 11 is driven to rotate clockwise around the pin shaft on the first connecting seat 10, so that the cover body 12 covers the top of the impregnation tank body; when the output shaft of the first cylinder 9 is retracted, the second connecting seat 11 is driven to rotate counterclockwise around the pin shaft on the first connecting seat 10, so that the cover body 12 moves upward away from the top of the impregnation tank body, and the output shaft of the first cylinder 9 is extended or retracted, thereby driving the cover body 12 to close and open the cover.

[0043] The sealing mechanism comprises a sealing ring 13 rotatably arranged on the top of the impregnation tank body, the sealing ring 13 is provided with grooves and convex teeth, the cover body 12 is provided with grooves and convex teeth matching therewith, a mounting plate is fixed on the top of the impregnation tank body, a second cylinder 14 is rotatably mounted on the end of the mounting plate, a shifting hole is provided on the end of the output shaft of the second cylinder 14, and the shifting rod on the sealing ring 13 extends into the shifting hole. When the output shaft of the second cylinder 14 extends out, the sealing ring 13 is driven to rotate counterclockwise, and when the output shaft of the second cylinder 14 is retracted, the sealing ring 13 is driven to rotate clockwise. When the groove on the sealing ring 13 corresponds to the convex teeth on the cover body 12, the cover body 12 can be extended into the sealing ring 13, and then the sealing ring 13 is rotated, so that the convex teeth of the sealing ring 13 are pressed on the convex teeth of the cover body 12, so that the cover body 12 is tightly pressed on the top of the impregnation tank body, and a sealing member is also provided between the cover body 12 and the impregnation tank body to form a sealed atmosphere in the impregnation tank.

[0044] The cover 12 is also provided with a vacuum port, a pressure gauge, and an observation port; the bottom of the impregnation tank is provided with an impregnation liquid inlet and an impregnation liquid outlet, and the side wall of the impregnation tank is also provided with a liquid level gauge 16 and a guide wheel 15. A plurality of guide wheels 15 are arranged along the rotation direction of the sealing ring 13 so that the sealing ring 13 can rotate stably.

[0045] A foot support 17 is fixedly provided at the bottom of the impregnation tank body, and the bottom of the foot support 17 is fixed on the base 7.

[0046] like Figure 4 As shown, an impregnation chamber is provided inside the impregnation tank, and a rotating wheel 18 is provided inside the impregnation chamber. When a mesh box provided with an airtight casting is placed on the rotating wheel 18, the rotating wheel 18 can drive the mesh box to rotate together; and a filtering mechanism is provided inside the rotating wheel 18.

[0047] like Figure 7 As shown, a central through hole is provided at the center of the rotating wheel 18, and a plurality of receiving grooves 35 are provided around the central through hole inside the rotating wheel 18, a movable block 32 is provided in the receiving groove 35, a slip ring 34 is slidably installed in the central through hole, the movable block 32 is fixedly connected to the slip ring 34 through a cross bar, concave arc surfaces are provided on both sides of the movable block 32, convex arc surfaces are provided on both sides of the receiving groove 35, a vertical mounting opening is provided on the side of the receiving groove 35 close to the central through hole, a filtering mechanism is installed in the vertical mounting opening, the filtering mechanism includes a filter plate 40 at the top and a liquid inlet facing the side of the receiving groove 35, when the rotating wheel 18 rotates, the movable block 32 always fits the convex arc surface on the side away from the rotation direction to form a flow channel facing the rotation direction, the liquid enters the filtering mechanism through the flow channel and flows out from the filter plate 40, and an avoidance groove for avoiding the cross bar is provided on the rear side wall of the filtering mechanism.

[0048] Specifically, the rotating wheel 18 is composed of an upper wheel plate 29, a movable block 32, a first connecting rod 33, a slip ring 34, a filter plate 40, a sediment collection box 54, and a lower wheel plate 39. A first flow port 31 is arranged at the center of the upper wheel plate 29, and a plurality of upper mounting ports 30 are also arranged on the upper wheel plate 29. The plurality of upper mounting ports 30 are arranged around the first flow port 31. A corresponding second flow port 38 and a lower mounting port 37 are arranged at the center of the lower wheel plate 39. The upper mounting ports 30 and the lower mounting ports 37 correspond to each other one by one. The upper mounting ports 30 and the lower mounting ports 37 form a vertical mounting port that penetrates the accommodating groove 35. A plurality of bosses 36 are also arranged on the lower wheel plate 39. An accommodating groove 35 is formed between the bosses 36. A movable block 32 is arranged in the groove 35, and multiple movable blocks 32 are fixedly connected to the slip ring 34 through the first connecting rod 33. The slip ring 34 is slidably connected to the first flow port 31 and the second flow port 38. The upper wheel plate 29 is fixedly connected to the lower wheel plate 39. A filter plate 40 is installed in the upper mounting port 30, and a sediment collecting box 54 is installed in the lower mounting port 37. The sediment collecting box 54 is provided with a liquid inlet on the side facing the accommodating groove 35. The rear side wall of the sediment collecting box 54 is provided with a first through groove 56 and a second through groove 57 for avoiding the first connecting rod 33, so that all the movable blocks 32 can rotate synchronously, and the rotation axis of the movable block 32 coincides with the axis of the upper wheel plate 29 and the lower wheel plate 39.

[0049] like Fig. 9 As shown, both sides of the boss 36 are provided with convex arc surfaces protruding toward the receiving groove 35, and both sides of the movable block 32 are provided with concave arc surfaces adapted thereto, and the width of the movable block 32 is smaller than the width of the receiving groove 35. When the rotating wheel 18 rotates clockwise, due to the inertia, the movable block 32 rotates counterclockwise relative to the rotating wheel 18, and the movable block 32 fits with the convex arc surface of the boss 36 on the side away from the rotation direction, that is, the concave arc surface on the right side of the movable block 32 fits with the convex arc surface on the left side of the boss 36. The convex arc surfaces on the left and right sides of the boss 36 and the concave arc surface on the left side of the movable block 32 form an arc-shaped clockwise flow channel 59, and the flow channel opening of the clockwise flow channel 59 is inclined toward the clockwise rotation direction. Multiple clockwise flow channels 59 are radially arranged around the axis. Therefore, when the rotating wheel 18 rotates clockwise, the impregnation liquid can flow into the sediment collection box 54 from the clockwise flow channel 59, and the impregnation liquid flowing in from the clockwise flow channel 59 flows out from the top filter plate 40, thereby filtering the sediment.

[0050] Similarly, if Fig.10As shown, when the rotating wheel 18 rotates counterclockwise, the movable block 32 will rotate clockwise relative to the rotating wheel 18 due to inertia. At this time, the concave arc surface on the left side of the movable block 32 fits with the convex arc surface on the right side of the previous boss 36, and the concave arc surface on the right side of the movable block 32 and the convex arc surface on the left side of the subsequent boss 36 form a counterclockwise flow channel 60 facing the counterclockwise rotation direction. Multiple clockwise flow channels 59 are radially arranged around the axis. When the rotating wheel 18 rotates counterclockwise, the impregnation liquid can flow from the counterclockwise flow channel 60 into the filter plate 40 at the top, and the sediment is blocked on the lower side of the filter plate 40, thereby filtering the sediment.

[0051] like Figure 8 As shown, a storage chamber is also formed at the lower part of the filter mechanism, and the storage chamber is blocked by a middle partition to form a first storage chamber 55 and a second storage chamber 58. A guide port and a sealing plate are arranged at the upper part of the first storage chamber 55 and the second storage chamber 58. The sealing plate is pushed by the movable block 32 to change its state, so that the sealing plate on the lower side of the storage chamber connected to the flow channel is in a closed state, and the sealing plate on the lower side of the storage chamber with the flow channel closed is in an open state.

[0052] Specifically, the filtering mechanism includes a sediment collection box 54, which is formed with a first receiving chamber 55 on the left and a second receiving chamber 58 on the right through a middle partition, and a filter plate 40 is arranged on the top of the sediment collection box 54, and a second guide plate 45 and a third guide plate 49 are also arranged on the upper part of the first receiving chamber 55 and the second receiving chamber 58 of the sediment collection box 54; the second guide plate 45 and the third guide plate 49 are both arranged in an inverted eight-shaped shape, and the second guide plate 45 is formed with a first guide port 46 that converges downward at the upper part of the first receiving chamber 55, and the third guide plate 49 is formed with a first guide port 46 that converges downward at the upper part of the first receiving chamber 55, and the third guide plate 49 is formed with a first guide port 46 that converges downward at the upper part of the first receiving chamber 55. 9, a second guide port 50 is formed at the upper part of the second receiving chamber 58, a first sealing plate 47 that can move left and right is arranged below the first guide port 46, a first through port 48 is arranged on the first sealing plate 47, a second sealing plate 51 that can move left and right is arranged below the second guide port 50, a second through port 52 is arranged on the second sealing plate 51, the first sealing plate 47 and the second sealing plate 51 move synchronously with the movable block 32, and the first through port 48 of the first sealing plate 47 is arranged on the right side, and the second through port 52 of the second sealing plate 51 is arranged on the left side, as shown in FIG. Figure 13-14 As shown, the clockwise flow channel 59 and the counterclockwise flow channel 60 can be switched by rotating the rotating wheel 18 clockwise and counterclockwise. When the clockwise flow channel 59 is formed, the first receiving chamber 55 is filled with liquid to form a filter chamber, and the second receiving chamber 58 is not filled with liquid to form a sedimentation chamber. When the counterclockwise flow channel 60 is formed, the first receiving chamber 55 is not filled with liquid to form a sedimentation chamber, and the second receiving chamber 58 is filled with liquid to form a filter chamber, and the sealing plate will move synchronously so that the sealing plate of the filter chamber is in a closed state, while the sealing plate of the sedimentation chamber is in an open state.

[0053] like Fig. 9 , Fig.14As shown, when the rotating wheel 18 rotates clockwise, the movable block 32 moves to the right side of the receiving groove 35, and a clockwise flow channel 59 is formed on the left side of the receiving groove 35. The clockwise flow channel 59 faces the first receiving chamber 55 on the left side of the sediment collecting box 54. At this time, the first sealing plate 47 and the second sealing plate 51 move to the right side synchronously with the movable block 32. The first sealing plate 47 is arranged at the first through opening 48 on the right side and moves to the bottom of the second guide plate 45. The first sealing plate 47 closes the first receiving chamber 55. Therefore, the inflowing impregnation liquid cannot enter the first receiving chamber 55, and directly flows out from the upper filter plate 40, and the sediment is After being filtered by the filter plate 40, the first receiving chamber 55 forms a filtering chamber; at the same time, the second sealing plate 51 is arranged at the second through port 52 on the left side and moves to the bottom of the second guide port 50. At this time, the second through port 52 corresponds to the second guide port 50 up and down, and the movable block 32 closes the liquid inlet of the second receiving chamber 58, so no infiltration liquid enters the second receiving chamber 58 from the counterclockwise flow channel 60. The sediment on the filter plate at the top of the second receiving chamber 58 settles onto the third guide plate 49, slides along the guide plate to the second guide port 50, and finally enters the second receiving chamber 58 through the second through port 52, thereby forming a sedimentation chamber.

[0054] like Figure 11-12 As shown, a slide groove 53 is also provided on the upper part of the sediment collection box 54, and a baffle 41 is slidably installed in the slide groove 53. The baffle 41 is fitted under the filter plate 40, and the baffle 41 is fixedly connected with the first sealing plate 47 and the second sealing plate 51 through the second connecting rod 44. The baffle 41, the second connecting rod 44, the first sealing plate 47, and the second sealing plate 51 rotate synchronously, and the baffle 41 is provided with strip-shaped through grooves 43 at intervals.

[0055] like Fig.11 , Fig.13 As shown, when the rotating wheel 18 rotates clockwise, the second connecting rod 44, the first sealing plate 47, the second sealing plate 51 and the baffle 41 move to the right, the strip-shaped through groove 43 at the top of the first receiving chamber 55 corresponds to the filter hole 42, and the first sealing plate 47 at the lower side closes the first guide port 46, so that the impregnated liquid can flow out of the filter hole 42, thereby completing the filtering work through the clockwise flow channel 59, the baffle 41 at the top of the second receiving chamber 58 blocks the filter hole 42, and the second through port 52 of the second sealing plate 51 at the lower side is connected with the second guide port 50, at this time, the second receiving chamber 58 forms a closed space, and the upper filtering space is connected with the lower storage space, and the sediment is precipitated into the second receiving chamber 58 without the action of liquid flow to complete the collection;

[0056] Similarly, if Fig.12 , Fig.14As shown, when the rotating wheel 18 rotates counterclockwise, the second connecting rod 44, the first sealing plate 47, and the second sealing plate 51 move to the left side, and the baffle 41 at the top of the first receiving chamber 55 corresponds to the filter hole 42, thereby closing the top of the first receiving chamber 55, and the first through port 48 of the first sealing plate 47 on the lower side is connected with the first guide port 46, so that the upper filter space is connected with the lower storage space, and the movable block 32 will close the original flow channel inlet. At this time, the first receiving chamber 55 forms a closed space, and the upper filter space is connected with the lower storage space. The sediment is precipitated into the second receiving chamber 58 without the action of liquid flow to complete the collection. The strip groove 43 at the top of the second receiving chamber 58 corresponds to the filter hole 42, and the second sealing plate 51 on the lower side closes the second guide port 50. The infiltration liquid enters the second receiving chamber 58 from the counterclockwise flow channel 60 and then flows out from the top filter hole 42, thereby completing the filtration.

[0057] By rotating the rotating wheel 18 clockwise and counterclockwise, sediment filtering and sediment collection can be performed synchronously. The alternating clockwise and counterclockwise or simultaneous rotation allows the filtration process to continue without interruption for sediment collection, thereby improving the overall filtration efficiency. The sediment can be effectively guided to the collection area to prevent it from being suspended again during the filtration process and affecting the filtration effect.

[0058] like Figure 5-Figure 6 As shown, a transmission device is provided at the lower side of the rotating wheel 18, and the transmission device includes a sealing cylinder 20 fixedly connected to the bottom of the impregnation tank, a shaft sleeve 24 is threadedly connected to the sealing cylinder 20, a shaft rod 27 is passed through the shaft sleeve 24, and the shaft rod 27 and the shaft sleeve 24 are circumferentially limited, a support rod 21 is fixed on the top of the shaft sleeve 24, a sliding sealing head 25 is slidably installed on the top of the sealing cylinder 20, the support rod 21 passes through the sliding sealing head 25 and is fixedly connected to the rotating wheel 18, the shaft rod 27 is driven to rotate by the driving motor 8, and the rotation axis of the rotating wheel 18 coincides with the shaft rod 27.

[0059] Specifically, a transmission device is installed at the lower part of the rotating wheel 18, including a sealing cylinder 20, a shaft rod 27, a sliding sealing head 25, a sleeve 24 and a support rod 21. The top of the support rod 21 is fixedly connected to the lower wheel plate 39 of the rotating wheel 18, and the bottom of the support rod 21 is fixedly connected to the sleeve 24. An external thread is arranged on the outer side of the sleeve 24, and an internal thread is arranged on the inner side of the sealing cylinder 20. The sleeve 24 is threadedly connected to the sealing cylinder 20. An axial hole 22 is arranged at the center of the sleeve 24, and a circumferential limiting strip 23 is arranged in the axial hole 22. The shaft rod 27 penetrates into the axial hole 22, and a corresponding circumferential limiting groove 28 is arranged on the shaft rod 27. The circumferential limiting strip 23 extends into the circumferential limiting groove 28. The top of the sealing cylinder 20 is sealingly and slidingly connected with a sliding sealing head 25, and a sliding sealing head 25 is provided There is an output hole 26, and the support rod 21 passes through the output hole 26. The lower side of the sealing cylinder 20 is fixedly connected to the impregnation tank body, and the lower side of the sealing cylinder 20 is provided with an opening connected to the external environment, so that when the shaft rod 27 rotates, the shaft sleeve 24 is driven to rotate synchronously, and the shaft sleeve 24 rotates and moves up and down in the sealing cylinder 20 through the thread. The shaft sleeve 24 moves up and down and rotates synchronously with the support rod 21, thereby driving the rotating wheel 18 to rotate and move up and down synchronously, so that the die-casting can move up and down. When the die-casting moves upward, the impregnation liquid flows to the die-casting from top to bottom, and when the die-casting moves downward, the impregnation liquid flows to the die-casting from bottom to top. By changing the flow direction of the impregnation liquid and the movement direction of the die-casting, uniform impregnation of various parts of the die-casting can be achieved. This helps to ensure the quality consistency of the entire die casting. Controlling the flow of the impregnation liquid in conjunction with the movement direction of the die casting can make more effective use of the impregnation liquid, reduce waste, and improve the impregnation efficiency. By precisely controlling the flow direction of the impregnation liquid and the movement of the die casting, it can be ensured that the impregnation liquid fully penetrates into the tiny pores of the die casting, thereby improving the impregnation quality and the overall performance of the die casting.

[0060] like Figure 2 As shown, the shaft rod 27 passes through the sealing cylinder 20 and is rotatably connected to the bearing seat, and the lower end of the shaft rod 27 is fixed to a driven wheel, which is connected to the driving wheel through a transmission belt. The driving wheel is fixed on the output shaft of the driving motor 8, and the driving motor 8 is installed on the frame, and the frame is fixed on the base 7.

[0061] like Figure 5 As shown, a plurality of first guide plates 19 are fixed on the upper wheel plate 29, and the first guide plates 19 are radially arranged. When the rotating wheel 18 rotates, the impregnation liquid can be guided to the die-casting at the center through the first guide plates 19, or the impregnation liquid at the center can be guided to the outside through the first guide plates 19. Through the guiding effect of the first guide plates 19, the impregnation liquid can be more evenly distributed in various parts of the die-casting, thereby improving the uniformity of the impregnation.
