Description

Technical Field

[0001] This invention relates to the field of mold cavity quality control technology, specifically to a device and method for controlling the surface quality of casting mold cavities. Background Technology

[0002] Casting is a method of pouring molten metal (or other materials) into a mold cavity of a specific shape, and obtaining a part of the desired shape after it cools and solidifies. The mold can be a sand mold, a metal mold (such as a die casting mold or a gravity casting mold), a plaster mold, a ceramic mold, etc. After a period of use, the surface of the mold cavity of a specific shape will develop quality problems such as roughness or defects. Therefore, it is necessary to control the surface quality of the casting mold cavity in order to ensure the quality of continuously cast products.

[0003] In existing technologies, when quality problems occur in the cavity of a casting mold and require adjustment, traditional methods such as chemical cleaning or electropolishing are generally used to improve the surface quality of the cavity. However, this requires the casting mold cavity to come into direct contact with chemical materials or electropolishing equipment, which can easily lead to physical wear or chemical corrosion on the mold, reducing the pass rate of mold cavity quality control. Laser cleaning is used to avoid direct contact between the mold cavity and the laser cleaning components. However, due to the different surface shapes and multifaceted nature of the mold cavity, laser cleaning that moves back and forth cannot meet the quality control requirements, thus reducing the quality of laser cleaning control of the mold cavity surface.

[0004] Therefore, we propose a device and method for controlling the surface quality of casting mold cavities to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a device and method for controlling the surface quality of casting mold cavities, in order to solve the problem mentioned in the background art that the surface shape of the mold cavity is not uniform and has multiple facets, and that laser cleaning by back-and-forth movement cannot meet the quality control requirements.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a surface quality control device and method for casting mold cavities, comprising a worktable, a strip column, and a collection box. A control box is fixedly installed on the top of the worktable. A grooved block is fixedly installed on one side of the inner wall of the control box. A fixed shaft is fixedly installed between the inner surface walls of the grooved block. A rotating block is rotatably connected to the outer surface wall of the fixed shaft. A fixed plate is fixedly installed on one side of the outer wall of the strip column. A rotating rod is rotatably connected to one side of the outer wall of the fixed plate. A placement plate is fixedly installed on the outer surface wall of the rotating rod. Two concave blocks are fixedly installed at the bottom of the strip column. A support shaft is fixedly installed between the inner surface walls of the two concave blocks. A connecting block is rotatably connected to the outer surface walls of the two support shafts. Two fixed blocks are fixedly installed at the bottom of the inner wall of the control box. A fixed rod is fixedly installed between the outer surface walls of the two fixed blocks. Two rectangular blocks are rotatably connected to the outer surface wall of the fixed rod. An electric push rod is fixedly installed on one side of the outer wall of each of the two rectangular blocks, and the output ends of the two electric push rods are fixedly connected to one side of the outer wall of the two connecting blocks.

[0007] Preferably, a cross slide rail is fixedly installed on the top of the inner wall of the control box, a laser cleaning component is movably embedded in the inner surface of the cross slide rail, and a cross groove is opened on the top of the placement plate.

[0008] Preferably, four sliding blocks are movably embedded in the inner surface of the cross groove, four small cylinders are fixedly installed on the top of the placement plate, and clamps are fixedly installed on the output ends of the four small cylinders, and the bottom of the four clamps are fixedly connected to the top of the four sliding blocks.

[0009] Preferably, a protective cover is fixedly installed on the top of the strip column, and a drive motor is fixedly installed on one side of the outer wall of the strip column.

[0010] Preferably, the top of the strip column is provided with a movable groove, and a reciprocating screw is fixedly installed on one side of the outer wall of the drive motor, with the outer wall of the reciprocating screw movably inserted into the inside of the strip column.

[0011] Preferably, the outer wall of the reciprocating screw is threadedly connected to a movable slider, and the outer wall of the movable slider is movably embedded inside the movable groove.

[0012] Preferably, a toothed rack is fixedly installed on the top of the movable slider, and a gear is fixedly installed on the outer wall of the rotating rod, with the outer wall of the gear meshing with the top of the toothed rack.

[0013] Preferably, blocks are fixedly installed on both sides of the outer wall of the toothed rack, and a control terminal is fixedly installed on one side of the outer wall of the control box.

[0014] Preferably, a fan is fixedly installed on the back of the control box, and a dust collection pipe is fixedly installed on the back of the control box, with the output end of the dust collection pipe connected to the interior of the collection box.

[0015] A method for adjusting the surface quality of a casting mold cavity includes the following steps: S1. When it is necessary to adjust the surface quality of the casting mold cavity, place it on the placement plate, and then start four small cylinders simultaneously through the control terminal. Under the action of the cross slide and four sliding blocks, the four clamping plates can be moved to clamp the casting mold cavity. Then, the surface quality of the casting mold cavity can be adjusted through the action of the cross slide and laser cleaning components.

[0016] S2. When laser cleaning is required on different positions of the surface of the casting mold cavity, the two electric push rods are started by the control end. Then, under the action of the two fixed blocks, fixed rods, two rectangular blocks, two concave blocks, two support shafts and two connecting blocks, the strip column, fixed plate, rotating rod and placement plate and rotating block are driven to rotate up and down along the fixed axis. The laser cleaning component can then perform multi-face quality control.

[0017] S3. Next, the drive motor can be started through the control terminal. Under the action of the strip column, the moving groove and the reciprocating screw, it drives the moving slider and the gear row to move back and forth along the moving groove, which can drive the gear, the rotating rod and the placement plate to swing left and right. The laser cleaning component can then further control the quality of the laser cleaning component.

[0018] S4. Finally, through the action of the fan and dust collection pipe, the smoke and dust generated by laser cleaning in the control box can be absorbed and concentrated in the collection box for subsequent processing.

[0019] Compared with the prior art, the beneficial effects of the present invention are: 1. Under the action of the cross groove and four sliding blocks, four small cylinders drive four clamping plates to move, which can clamp the mold cavity. Then, the control terminal starts two electric push rods, which drive two rectangular blocks to rotate on the fixed rod. At the same time, two concave blocks also rotate on two support shafts. Since the placement plate is rotatably connected to the inside of the rotating block and the fixed plate through the rotating rod, the extension and retraction of the two electric push rods can drive the rotating block to rotate along the fixed shaft inside the groove block. This can drive the strip column and the placement plate to rotate up and down along the fixed shaft, and can increase the cleaning area of ​​the laser cleaning component and the surface of the mold cavity, thus improving the quality of laser cleaning control of the surface of the casting mold cavity.

[0020] 2. Next, the drive motor is started through the control terminal. Under the action of the moving groove and the reciprocating screw, the moving slider and the gear row can be driven to move back and forth along the moving groove. This can drive the gear and the rotating rod to rotate inside the fixed plate and the rotating block, which in turn can drive the placement plate and the clamped mold cavity to rotate back and forth. This further increases the contact area between the laser cleaning component and the surface of the mold cavity, and further improves the quality of laser cleaning control of the surface of the casting mold cavity. Then, through the action of the fan, dust collection pipe and collection box, the smoke and dust generated by laser cleaning in the control box can be absorbed and treated in the subsequent process.

[0024] Please see Figures 1-7 This invention provides a technical solution: a device and method for controlling the surface quality of a casting mold cavity, comprising a workbench 1, a strip column 8, and a collection box 32. A control box 2 is fixedly installed on the top of the workbench 1. A grooved block 5 is fixedly installed on one side of the inner wall of the control box 2. A fixed shaft 6 is fixedly installed between the inner walls of the grooved block 5. A rotating block 7 is rotatably connected to the outer wall of the fixed shaft 6. A fixed plate 9 is fixedly installed on one side of the outer wall of the strip column 8. A rotating rod 10 is rotatably connected to one side of the outer wall of the fixed plate 9. A placement plate 11 is fixedly installed on the outer wall of the rotating rod 10. The bottom of the strip column 8... Two concave blocks 12 are fixedly installed in the control box 2. A support shaft 13 is fixedly installed between the inner walls of the two concave blocks 12. A connecting block 14 is rotatably connected to the outer walls of the two support shafts 13. Two fixing blocks 15 are fixedly installed at the bottom of the inner wall of the control box 2. A fixing rod 16 is fixedly installed between one side of the outer wall of the two fixing blocks 15. Two rectangular blocks 17 are rotatably connected to the outer wall of the fixing rod 16. An electric push rod 18 is fixedly installed on one side of the outer wall of the two rectangular blocks 17. The output ends of the two electric push rods 18 are fixedly connected to one side of the outer wall of the two connecting blocks 14.

[0025] like Figures 1-5 As shown, a cross slide rail 3 is fixedly installed on the top of the inner wall of the control box 2. A laser cleaning component 4 is movably embedded in the inner surface of the cross slide rail 3. A cross slide groove 19 is opened on the top of the placement plate 11. The laser cleaning component 4 includes a laser, a laser nozzle and a control system, which can complete the laser cleaning control of the surface of the casting mold cavity. Under the action of the cross slide rail 3, the area to be laser cleaned can be increased.

[0026] like Figures 4-6 As shown, four sliding blocks 20 are movably embedded in the inner wall of the cross slide groove 19, and four small cylinders 21 are fixedly installed on the top of the placement plate 11. Clamping plates 22 are fixedly installed on the output ends of the four small cylinders 21, and the bottoms of the four clamping plates 22 are fixedly connected to the tops of the four sliding blocks 20. Since the four sliding blocks 20 are movably embedded in the cross slide groove 19, the four clamping plates 22 can be moved by the four small cylinders 21, and casting mold cavities of different sizes can be clamped on the placement plate 11.

[0027] like Figures 4-7As shown, a protective cover 23 is fixedly installed on the top of the strip column 8, and a drive motor 24 is fixedly installed on one side of the outer wall of the strip column 8. Through the function of the protective cover 23, foreign objects can be prevented from falling on the moving groove 25, the reciprocating screw 26 or the gear rack 28, thus affecting the smoothness of the transmission.

[0028] like Figures 4-7 As shown, a movable groove 25 is provided on the top of the strip column 8, and a reciprocating screw 26 is fixedly installed on one side of the outer wall of the drive motor 24, and the outer wall of the reciprocating screw 26 is movably inserted into the inside of the strip column 8.

[0029] like Figure 2 and Figures 4-7 As shown, the outer wall of the reciprocating screw 26 is threadedly connected to a movable slider 27, and the outer wall of the movable slider 27 is movably embedded in the inside of the movable groove 25. Since the movable slider 27 is movably embedded in the inside of the movable groove 25 and is also threadedly connected to the outer wall of the reciprocating screw 26, the reciprocating screw 26 can be rotated by the drive motor 24, so that the movable slider 27 can move back and forth along the movable groove 25.

[0030] like Figure 2 and Figures 4-7 As shown, a toothed rack 28 is fixedly installed on the top of the movable slider 27, and a gear 29 is fixedly installed on the outer wall of the rotating rod 10. The outer wall of the gear 29 is meshed with the top of the toothed rack 28. Since the toothed rack 28 is installed on the top of the movable slider 27, the movement of the movable slider 27 and the toothed rack 28 can drive the gear 29 and the rotating rod 10 to rotate inside the rotating block 7 and the fixed plate 9.

[0031] like Figures 1-4 and Figure 7 As shown, two stops 30 are fixedly installed on both sides of the outer wall of the gear rack 28, and a control terminal 31 is fixedly installed on one side of the outer wall of the control box 2. Through the action of the two stops 30, the gear rack 28 can be prevented from disengaging from the gear 29, ensuring the smoothness of transmission. Secondly, the control terminal 31 is electrically connected to the control systems of the two electric push rods 18, the drive motor 24, and the laser cleaning component 4, and has automatic control.

[0032] like Figures 1-3 and Figure 7 As shown, a fan 33 is fixedly installed on the back of the control box 2, and a dust collection pipe 34 is fixedly installed on the back of the control box 2. The output end of the dust collection pipe 34 is connected to the inside of the collection box 32. Through the action of the fan 33, the dust collection pipe 34 and the collection box 32, the smoke and dust generated by laser cleaning in the control box 2 can be absorbed and concentrated in the collection box 32 for subsequent processing.

[0033] The operating method and working principle of this device are as follows: First, place the casting mold cavity requiring quality control on the placement plate 11, and start the four small cylinders 21 through the control terminal 31. Since the four sliding blocks 20 installed at the bottom of the four clamping plates 22 are movably embedded inside the cross slide groove 19, the four clamping plates 22 can be moved relative to each other, clamping the casting mold cavity onto the placement plate 11. Close the control box 2 door, and start the laser cleaning component 4 through the control terminal 31, so that it moves on the cross slide rail 3 and performs laser cleaning quality control on the surface of the clamped casting mold cavity. At this time, start the laser cleaning component 4 through the control terminal 31 again. The electric actuators 18 are mounted on two rectangular blocks 17. Since both rectangular blocks 17 are rotatably connected to the fixed rods 16 between two fixed blocks 15, and connecting blocks 14 are fixedly installed at the output ends of both electric actuators 18, and both connecting blocks 14 are mounted on the support shafts 13 inside the two concave blocks 12, and since the strip column 8 and the fixed plate 9 are connected to the rotating block 7 through the rotating rod 10, and the rotating block 7 is rotatably connected to the fixed shaft 6 inside the slotted block 5, the extension and retraction of the two electric actuators 18 can drive the two connecting blocks 14 and the two rectangular blocks 17 to rotate on the two support shafts 13 and the fixed rods 16 respectively. Simultaneously, it can drive the rotating rod 10, the placement plate 11, and the rotating block 7 to rotate on the fixed shaft 6, thereby causing the placement plate 11 to rotate up and down along the fixed shaft 6. At the same time, the drive motor 24 installed on one side of the outer wall of the strip column 8 can be started through the control terminal 31, so that it drives the reciprocating screw 26 to rotate inside the strip column 8. Since the movable slider 27 is movably embedded in the movable groove 25 and is also threaded to the outer wall of the reciprocating screw 26, the movable slider 27 and the gear rack 28 can move back and forth along the movable groove 25. Also, because the gear 29 is fixedly installed on the outer wall of the rotating rod 10, its gear The gear 29 meshes with the gear rack 28, and the movement of the gear rack 28 can drive the gear 29 and the rotating rod 10 to rotate between the fixed plate 9 and the rotating block 7, thereby causing the placement plate 11 to rotate back and forth along the rotating rod 10. In general, when the casting mold cavity is clamped in the placement plate 11, the rotation of the placement plate 11 in the front, back and left and right directions can increase the area of ​​the laser cleaning component 4 for controlling the surface quality of the cavity, enabling it to perform laser cleaning on the surface of cavities of different shapes, improving the quality of laser cleaning control of the casting mold cavity surface, and thus improving the effectiveness of the casting mold cavity surface quality control device.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
