Technical Field

[0001] The present application relates to the field of automatic cleaning technology, and in particular to an automatic cleaning method and device for a cast steel wheel mold. Background Art

[0002] As an advanced casting process, graphite mold casting is widely used in the fields of automobiles, aerospace, etc. This process uses a mold made of graphite material to pour metal, which can not only improve the quality of castings, but also reduce production costs. However, after each casting, the coating and sand on the graphite mold need to be cleaned, and the hard lumps of gravel in the sand trough need to be scraped loose for subsequent use. This process is of great significance to ensure the quality of castings and extend the life of the graphite mold.

[0003] A related cleaning work after graphite mold casting mainly relies on manual operation. Manual cleaning is usually done by workers using brushes or other tools to clean the graphite mold surface one by one.

[0004] When the graphite model is cleaned manually, the graphite mold surface needs to be cleaned one by one with a brush during the cleaning process, so the entire cleaning cycle is long and time-consuming, which directly affects the production efficiency of metal castings. Summary of the invention

[0005] In order to improve the cleaning efficiency, the present application provides a method and device for automatically cleaning a cast steel wheel mold.

[0006] The present application provides an automatic cleaning device for a cast steel wheel mold, which adopts the following technical solution: An automatic cleaning device for a cast steel wheel mold comprises a mounting frame, the mounting frame being fixedly arranged on the ground, a graphite casing, the graphite casing being arranged in the mounting frame, and further comprising: A movable frame, the movable frame being vertically slidably disposed on the mounting frame; A motor, wherein the motor is fixedly arranged at the upper end of the movable frame; A cleaning assembly, the cleaning assembly is rotatably disposed on the movable frame and is used for cleaning the graphite casing; A crushing member, the crushing member is fixedly connected to the cleaning assembly and is used to crush gravel on the graphite casing; A scraping rod, one end of which is slidably connected to the cleaning assembly through a matching piece, and the other end of which is placed in the graphite casing to scrape off the gravel in the graphite casing.

[0007] By adopting the above technical solution, through the sliding setting of the movable frame and the rotation of the cleaning component driven by the motor, the cleaning component can evenly clean the surface of the graphite casing, effectively remove paint and sand particles, the crushing part can effectively crush the gravel on the graphite casing, and the scraping rod can clean the grooves of the graphite casing, thereby improving the cleaning efficiency.

[0008] Optionally, the cleaning component includes: A rotating plate, the rotating plate is fixedly connected to the output shaft of the motor; A matching column, one end of which is fixedly connected to the output shaft of the motor, and the other end of which is fixedly connected to the rotating plate, and a rack is fixedly arranged in the inner circumference of the matching column; a driving gear meshing with the rack; A driven gear meshing with the driving gear; A driven rod, one end of which is fixedly connected to the driven gear, and the other end of which penetrates the rotating plate; A first bevel gear, the first bevel gear being fixedly connected to one end of the driven rod penetrating the rotating plate; a first driving member, the driving member being meshed with the first bevel gear; A cleaning brush is fixedly connected to the driving member.

[0009] By adopting the above technical solution, when the motor is started, the matching column drives the rotating plate to rotate. At the same time, during the rotation of the matching column, the driving gear is driven to rotate, and then the driven gear drives the driven rod to rotate. The rotation of the driven rod drives the first bevel gear to rotate, and then the driving member drives the cleaning brush to rotate while following the rotation of the rotating plate, thereby cleaning the surface of the graphite sleeve box, which is simple and convenient.

[0010] Optionally, the first driving member includes: a second bevel gear, the second bevel gear meshing with the first bevel gear; A first transmission rod, one end of which is fixedly connected to the axis of the second bevel gear; a third bevel gear, the third bevel gear being fixedly connected to an end of the first transmission rod away from the second bevel gear; a fourth bevel gear, the fourth bevel gear meshing with the third bevel gear; A second transmission rod, one end of the second transmission rod is fixedly connected to the axis of the fourth bevel gear, and the other end of the second transmission rod is fixedly connected to the cleaning brush.

[0011] By adopting the above technical solution, the second bevel gear is meshed with the first bevel gear. When the first bevel gear rotates, the second bevel gear follows the rotation, converting the vertical force into the horizontal force, and at the same time driving the first transmission rod to rotate, thereby causing the third bevel gear to rotate, and then the fourth bevel gear drives the second transmission rod and the cleaning brush to rotate, further increasing the cleaning efficiency.

When the crushing needle contacts the graphite sleeve, the movable frame continues to move downward, so that the connecting rod drives the mounting plate to move into the mounting cavity, squeezes the airbag column, and then the matching pulley and the second pulley approach each other. Due to the setting of the magnet, when the matching pulley rotates, the second pulley is driven to rotate in the opposite direction, thereby driving the connecting rod to rotate. Since the mounting plate is threadedly connected to the connecting plate, the connecting rod drives the mounting plate to rotate during the rotation process. Under the action of the guide rod, the mounting plate moves vertically along the axis of the connecting rod, thereby crushing sand and gravel.

[0016] Optionally, a first telescopic rod is provided at one end of the sand scraping rod, and the first telescopic rod is connected to the airbag column through a connecting piece, and the connecting piece includes: a first connecting tube, one end of which is connected to the airbag column, and the other end of which is connected to the rodless cavity of the first telescopic rod, wherein an air inlet and an air outlet are provided in the first connecting tube; An opening and closing plate, the opening and closing plate is rotatably arranged on the air inlet; An extrusion column, the upper end of which is fixedly disposed on one side of the first telescopic rod; A second telescopic rod, wherein one end of the second telescopic rod having a rod cavity is fixedly arranged at one side of the air outlet, the second telescopic rod having a rod cavity connected to the first connecting pipe, and the telescopic end of the second telescopic rod is used to open and close the air outlet; A second connecting tube, one end of which is connected to the rodless cavity of the second telescopic rod, and the other end of which is connected to the extrusion column.

[0019] By adopting the above technical solution and arranging the positioning pins and the positioning sleeves, the positions of the movable frame and the graphite sleeve box can be limited.

[0020] Optionally, a baffle is fixedly provided on one side of the crushing needle.

[0021] By adopting the above technical solution, the baffle is set and the crushing needle is placed. When crushing large gravel, the gravel splashes and causes damage to the graphite casing.

[0022] Optionally, a method for automatically cleaning a cast steel wheel mold comprises: S1.

The scraping rod 14 is arranged in a cone shape at one end close to the graphite casing 11. It should be noted that the scraping rod 14 penetrates into the groove in the graphite casing 11, and the groove in the graphite casing 11 can be cleaned when the motor 13 is started. It should be noted that controlling the mobile frame 12 to slide up and down on the mounting frame 1 is common knowledge known to those skilled in the art. It can be driven electrically, pneumatically or hydraulically, and the embodiments of the present application will not be repeated. A positioning pin 15 is fixedly arranged on the graphite sleeve 11, and a positioning sleeve 16 is fixedly arranged at the lower end of the mobile frame 12, and the positioning pin 15 and the positioning sleeve 16 are arranged correspondingly. The arrangement of the positioning pin 15 can determine the position of the mobile frame 12. A baffle 17 is fixedly arranged on one side of the crushing needle 34. The arrangement of the baffle 17 can prevent the crushed stones from splashing.

[0030] During specific use, when the graphite sleeve 11 moves to the position of the mounting frame 1, the movable frame 12 is driven to slide up and down on the mounting frame 1, so that the cleaning component contacts the surface of the graphite sleeve 11, and then the motor 13 is started so that the motor 13 drives the movable frame 12 to rotate. When the cleaning component contacts the graphite sleeve 11, the scraping rod 14 will extend into the sand hanging groove of the graphite sleeve 11, and then under the drive of the motor 13, the cleaning component, the crushing part 3 and the scraping rod 14 will rotate, and clean the graphite sleeve 11, thereby improving the cleaning efficiency.

[0031] Combination Figure 3 , Figure 4 and Figure 5 In a specific application embodiment, the cleaning assembly includes a rotating plate 21, a matching column 22, a driving gear 23, a driven rod 25, a first bevel gear 26, a first driving member 27, and a cleaning brush 28. The rotating plate 21 is fixedly connected to the output shaft of the motor 13; one end of the matching column 22 is fixedly connected to the output shaft of the motor 13, and the other end of the matching column 22 is fixedly connected to the rotating plate 21, and a rack is fixedly arranged in the inner circumference of the matching column 22; the driving gear 23 is meshed with the rack; the driven gear 24 is meshed with the driving gear 23; one end of the driven rod 25 is fixedly connected to the driven gear 24, and the other end of the driven rod 25 is penetrated through the rotating plate 21; the first bevel gear 26 is fixedly connected to one end of the driven rod 25 penetrating the rotating plate 21; the first driving member 27 is meshed with the first bevel gear 26; and the cleaning brush 28 is fixedly connected to the driving member.

[0032] Specifically, the first driving member 27 includes a second bevel gear 271, a first transmission rod 272, a third bevel gear 273, a fourth bevel gear 274, and a second transmission rod 275. The second bevel gear 271 is meshed with the first bevel gear 26; one end of the first transmission rod 272 is fixedly connected to the axis of the second bevel gear; the third bevel gear 273 is fixedly connected to an end of the first transmission rod 272 away from the second bevel gear; the fourth bevel gear 274 is meshed with the third bevel gear 273; one end of the second transmission rod 275 is fixedly connected to the axis of the fourth bevel gear 274, and the other end of the second transmission rod 275 is fixedly connected to the cleaning brush 28.

[0033] In the embodiment of the present application, the rotating plate 21 can be square or circular. It should be noted that when the rotating plate 21 is square, it needs to be able to rotate in the mobile frame 12 and can rotate and clean the graphite sleeve 11. The matching column 22 is set in a cylindrical shape. The matching column 22 and the output shaft of the motor 13 can be set by an integral molding or fixedly connected by welding or bolting. Among them, the matching column 22 is hollow, and the diameter of the matching column 22 matches the output shaft of the motor 13. The rack will be circumferentially arranged along the inner wall of the matching column 22, and the width of the rack is equal to the thickness of the driving gear 23, so as to ensure the rotation stability of the driven rod 25. The material of the cleaning brush 28 should have good flexibility and durability. It can be nylon bristles or polypropylene bristles. The specific setting depends on the usage, and the embodiment of the present application does not make specific limitations.

[0034] The second bevel gear 271 and the third bevel gear 273 are located on the same horizontal plane, the first bevel gear 26, the second bevel gear 271 and the first transmission rod 272 are on the same axis, and the connection method between the second transmission rod 275 and the cleaning brush 28 is not specifically limited, as long as the cleaning brush 28 can rotate with the rotation of the second transmission rod 275.

[0035] In specific use, when the motor 13 is started, its output shaft will drive the rotating plate 21 and the matching column 22 to rotate together, and the rack in the matching column 22 will drive the driving gear 23 to rotate, thereby driving the driven gear 24 to rotate. The rotation of the driven gear 24 will be transmitted to the first bevel gear 26 through the driven rod 25, so that the first bevel gear 26 rotates accordingly. The rotation of the first bevel gear 26 will drive the second bevel gear 271 meshed therewith to rotate. The rotation of the second bevel gear 271 will be transmitted to the third bevel gear 273 through the first transmission rod 272, so that the third bevel gear 273 rotates accordingly. The rotation of the third bevel gear 273 will further drive the fourth bevel gear 274 meshed therewith to rotate. The rotation of the fourth bevel gear 274 will be transmitted to the cleaning brush 28 through the second transmission rod 275, so that the cleaning brush 28 moves and cleans along a predetermined trajectory. It should be noted that since one end of the matching column 22 is fixedly connected to the output shaft of the motor 13, and the other end of the matching column 22 is fixedly connected to the rotating plate 21, when the motor 13 is started, the cleaning brush 28 can rotate along with the rotating plate 21, that is, during cleaning, the cleaning brush 28 can rotate along with the rotating plate 21.

[0036] Combination Figure 5 In a specific application embodiment, the crushing member 3 includes a connecting rod 31, a guide rod 32, a mounting plate 33, and a crushing needle 34. The connecting rod 31 penetrates the rotating plate 21, and the connecting rod 31 is rotatably connected to the rotating plate 21; one end of the guide rod 32 is fixedly arranged below the rotating plate 21; one end of the mounting plate 33 is slidably arranged on the guide rod 32, and the other end of the mounting plate 33 is rotatably arranged on the connecting rod 31; the crushing needle 34 is fixedly arranged below the mounting plate 33. The rotating plate 21 is provided with a mounting cavity 35, and a second driving member 4 is provided at one end of the connecting rod 31 penetrating the rotating plate 21. The second driving member 4 includes a first pulley 41, an airbag column 42, a matching pulley 43, and a second pulley 44. The first pulley 41 is fixedly arranged at one end of the driven rod 25 penetrating the rotating plate 21; the airbag column 42 is fixedly arranged at the upper end of the mounting cavity 35; the matching pulley 43 is sleeved on the outer peripheral side of the airbag column 42, and the upper end of the matching pulley 43 is rotatably arranged at the upper end of the mounting cavity 35; the second pulley 44 is fixedly arranged at one end of the connecting rod 31 penetrating the rotating plate 21; the matching belt 45 is wound around the matching pulley 43 and the first pulley 41; wherein, a magnet is arranged at one end of the matching pulley 43 and the second pulley 44 close to each other.

[0037] In the embodiment of the present application, the mounting plate 33 is provided with a rotating hole for the connecting rod 31 to rotate. It should be noted that a thread is provided at one end of the connecting rod 31 close to the connecting plate, and the connecting plate is threadedly connected to the connecting rod 31. The shape and material of the crushing needle 34 should be determined according to the nature of the crushed object and the requirements of the crushing effect. The shape of the mounting cavity 35 is the same as that of the rotating plate 21. The airbag column 42 is fixedly arranged at the upper end of the mounting cavity 35, wherein the airbag column 42 is embedded in the inner side of the matching pulley 43. It should be noted that a magnet is provided at one end where the matching pulley 43 and the second pulley 44 are close to each other, wherein the magnet diameter of the second pulley 44 is larger than the magnet diameter of the matching pulley 43.

[0038] During specific use, when the driven rod 25 rotates, it drives the first pulley 41 to rotate. Due to the setting of the matching belt, the first pulley 41 drives the matching pulley to rotate when it rotates. When the crushing needle 34 contacts the graphite sleeve 11, the movable frame 12 continues to move downward, so that the connecting rod 31 drives the mounting plate 33 to move into the mounting cavity 35, squeezing the airbag column 42, and then the matching pulley and the second pulley 44 approach each other. Due to the setting of the magnet, when the matching pulley 43 rotates, the second pulley 44 is driven to rotate in the opposite direction, thereby driving the connecting rod 31 to rotate. Since the mounting plate 33 is threadedly connected to the connecting plate, the connecting rod 31 drives the mounting plate 33 to rotate during the rotation process. Under the action of the guide rod 32, the mounting plate 33 moves vertically along the axis of the connecting rod 31, thereby crushing sand and gravel.

[0039] Combination Figure 5 , Figure 6 and Figure 7 Specifically, a first telescopic rod 51 is provided at one end of the scraping rod 14, and the first telescopic rod 51 is connected to the airbag column 42 through a connecting piece 6, and the connecting piece 6 includes a first connecting pipe 61, an opening and closing plate 62, an extrusion column 63, a second telescopic rod 64, and a second connecting pipe 65. One end of the first connecting pipe 61 is connected to the airbag column 42, and the other end of the first connecting pipe 61 is connected to the rodless cavity of the first telescopic rod 51, wherein an air inlet 52 and an air outlet 53 are provided in the first connecting pipe 61; the opening and closing plate 62 is rotatably arranged on the air inlet 52; the upper end of the extrusion column 63 is fixedly arranged on one side of the first telescopic rod 51; one end of the second telescopic rod 64 with a rod cavity is fixedly arranged on one side of the air outlet 53, and the second telescopic rod 64 has a rod cavity connected to the first connecting pipe 61, and the telescopic end of the second telescopic rod 64 is used to open and close the air outlet 53; one end of the second connecting pipe 65 is connected to the rodless cavity of the second telescopic rod 64, and the other end of the second connecting pipe 65 is connected to the extrusion column 63.

[0040] In the embodiment of the present application, the first connecting tube 61 can be round or square, and the implementation of the present application does not make specific limitations. The air outlet 53 and the air inlet 52 are arranged in a square shape, and the air inlet 52 and the air outlet 53 divide the first connecting tube 61 into two air passages. The opening and closing plate 62 is arranged in a square shape. The opening and closing plate 62 can realize that the gas of the airbag column 42 enters the first telescopic rod 51 through the first connecting tube 61, thereby driving the scraping rod 14 to clean the groove of the graphite sleeve 11. The extrusion column 63 is an elastic material, and an inert gas is arranged in the extrusion column 63. When the crushing needle 34 contacts the surface of the graphite sleeve 11, the extrusion column 63 will be squeezed, and the gas in the extrusion column 63 enters the rodless cavity of the second telescopic rod 64 through the second connecting tube 65, thereby driving the telescopic end of the second telescopic rod 64 The first telescopic rod 51 stretches and then closes the air outlet 53, so that the gas in the airbag column 42 can enter the first telescopic rod 51. When the movable frame 12 moves upward, the extrusion column 63 is no longer subjected to pressure, and the telescopic end of the second telescopic rod 64 moves toward the rodless cavity, so that the gas in the rodless cavity flows into the extrusion cavity, and the gas in the rodless cavity of the first telescopic rod 51 flows toward the direction of the airbag column 42. Due to the setting of the opening and closing plate 62, when the gas in the first telescopic rod 51 flows back, the opening and closing plate 62 is driven to close the air inlet 52, so that the gas in the first telescopic rod 51 flows back to the airbag column 42 through the air outlet 53. At the same time, since a spring is provided in the rodless cavity of the first telescopic rod 51, under the joint action of the spring recovery ability and the gas reflux, the scraping rod 14 is retracted and away from the groove of the graphite sleeve 11.

[0041] This embodiment provides an automatic cleaning method for a cast steel wheel mold.

[0043] The implementation principle of the embodiment of the present application is as follows: when the graphite sleeve 11 moves to the position of the mounting frame 1, the movable frame 12 is driven to slide up and down on the mounting frame 1. When the positioning sleeve 16 of the movable frame 12 is embedded with the positioning pin 15, the extrusion column 63 is squeezed, and at the same time, the crushing needle 34 contacts the surface of the graphite sleeve 11, and the matching pulley 43 and the second pulley 44 are close, and the connecting rod 31 squeezes the airbag column 42, so that the gas in the airbag column 42 enters the rodless cavity of the first telescopic rod 51 through the first connecting pipe 61, and drives the scraping rod 14 to extend into the groove of the graphite sleeve 11, and starts the motor 13. The motor 13 drives the cleaning component to contact the surface of the graphite sleeve 11, and then starts the motor 13, so that the motor 13 drives the rotating plate 21 to rotate, and the driving member drives the cleaning brush 28, the scraping rod 14, and the crushing needle 34 to rotate with the rotating plate 21. At the same time, the cleaning brush 28 rotates, and the crushing needle 34 moves up and down, so that the graphite sleeve 11 is cleaned and the cleaning efficiency is improved.
