Description

Technical Field

[0001] The invention relates to the technical field of casting mold coating cleaning, and more particularly to a coating cleaning device for the surface of a centrifugal casting mold. Background Art

[0002] Centrifugal casting is a technique and method in which liquid metal is poured into a high-speed rotating mold, causing the molten metal to perform centrifugal motion to fill the mold and form a casting. Due to the centrifugal motion, the liquid metal can well fill the mold in the radial direction and form a free surface of the casting. A cylindrical inner hole can be obtained without a core. Centrifugal casting helps to remove gas and inclusions in the liquid metal, affects the crystallization process of the metal, and thus improves the mechanical and physical properties of the casting. During centrifugal casting, to improve the surface quality of the cast product, a coating is evenly sprayed inside the centrifugal casting mold. The coating can reduce the surface roughness of the casting, making the casting surface smoother. By filling the pores on the casting surface, the coating prevents the infiltration of liquid metal. The coating can reduce the thermal shock of the molten metal on the metal mold, lowering the peak temperature of the metal mold, thereby extending the service life of the metal mold. The coating can also increase the density of the casting, reduce defects such as pores and slag inclusions, and thus improve the mechanical properties of the casting. When the centrifugal casting mold completes the casting process and the casting is taken out, the paint originally sprayed into the mold will remain inside the mold. Since the centrifugal casting mold is produced by centrifugal means, the products produced are generally tubular structures. The centrifugal casting mold is long, so it is difficult to clean the deep part of the centrifugal casting mold. In addition, the diameters of different castings are different, so the diameters of the cavities inside the centrifugal casting mold are different. Therefore, the current cleaning devices cannot clean different centrifugal casting molds. When cleaning a centrifugal casting mold, a special detergent is sprayed inside the mold. After cleaning, the detergent and water need to be removed. Today's cleaning devices cannot quickly remove the detergent or water. It is necessary to wait for the inside of the mold to dry before the next paint spraying can be carried out, which reduces overall work efficiency. Summary of the Invention

[0006] In a preferred embodiment, the side of the bidirectional screw away from the bidirectional screw is fixedly connected to a rotating wheel, the thread grooves on both sides of the bidirectional screw are mirror-symmetrical, the side of the movable plate away from the cleaning rod is in parallel contact with the side of the connecting block, and the side of the cleaning rod away from the output shaft and the side of the cleaning base plate away from the output shaft are in the same plane.

When the servo motor drives the threaded rod to rotate, the moving block drives the output shaft and the rotary motor to move via the support plate, thereby causing the cleaning mechanism to move inside the first centrifugal mold or the second centrifugal mold, thereby quickly cleaning the inner wall of the first centrifugal mold or the second centrifugal mold. When the first centrifugal mold or the second centrifugal mold is cleaned, cleaning liquid and water will remain in the first centrifugal mold or the second centrifugal mold. At this time, the water-gas dual-purpose pump is started and performs a pumping operation. When the water-gas dual-purpose pump is working, air is pumped through the telescopic tube, the connecting branch pipe and the absorption tube. When the absorption tube pumps air, the water and cleaning liquid in the first centrifugal mold can be pumped into a collection box, so that the interior of the first centrifugal mold or the second centrifugal mold is quickly dried, which is convenient for spraying centrifugal paint again.

All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] Reference Figure 1 and Figure 2The present invention provides a coating cleaning device for the surface of a centrifugal casting mold, comprising a first centrifugal mold 1, a moving mechanism 2 being provided on the side of the first centrifugal mold 1, a rotating motor 3 being fixedly connected to the top of the moving mechanism 2, an output shaft 4 being fixedly connected to the side of the rotating motor 3 away from the moving mechanism 2, a cleaning mechanism 5 being fixedly connected to the side of the output shaft 4 away from the rotating motor 3, an absorption mechanism 6 being movably connected to the side of the output shaft 4, and a second centrifugal mold 7 being provided on the side of the first centrifugal mold 1.

[0023] In the embodiment of the present application, the first centrifugal mold 1 and the second centrifugal mold 7 are connected to each other during casting production. After the mold is opened, the first centrifugal mold 1 and the second centrifugal mold 7 are separated. Figure 1 As shown, this application will clean the first centrifugal mold 1 and the second centrifugal mold 7 separately, and the length of the first centrifugal mold 1 and the second centrifugal mold 7 in this application can be adapted to the length of the output shaft 4 and the internal threaded rod 203 of the moving mechanism 2, and the specific length can be adjusted according to actual production conditions.

[0024] Reference Figure 3 、 Figure 4 as well as Figure 5 The cleaning mechanism 5 includes a connecting block 501 fixedly connected to the output shaft 4, a cleaning base plate 502 fixedly connected to the side of the connecting block 501 away from the output shaft 4, and two ends of the cleaning base plate 502 close to the side of the connecting block 501 are movably connected to a bidirectional screw 503, and both sides of each bidirectional screw 503 are threadedly connected to a movable plate 504, and the movable plate 504 is movably connected to a connecting plate 505 on the side away from the connecting block 501, and the connecting plate 505 is movably connected to a translation plate 506 on the side away from the movable plate 504, and the translation plate 506 is fixedly connected to a mounting ring 507 on the side away from the translation plate 506, and a cleaning rod 508 is fixedly connected to the interior of the mounting ring 507, and the bidirectional screw 503 is screwed to the side of the connecting block 501.

The bidirectional screws 503 on both sides rotate synchronously through the gear set 509, and the side of the bidirectional screw 503 away from the bidirectional screw 503 is fixedly connected to a runner 510, and the thread grooves on both sides of the bidirectional screw 503 are mirror-symmetrical, and the side of the movable plate 504 away from the cleaning rod 508 is in parallel contact with the side of the connecting block 501, and the side of the cleaning rod 508 away from the output shaft 4 is in the same plane as the side of the cleaning base plate 502 away from the output shaft 4.

[0025] When the two moving plates 504 move closer to each other, the connecting plate 505 is driven to rotate. When the connecting plate 505 rotates, the translation plate 506 moves away from the two-way screw 503, thereby making the cleaning rods 504 on both sides move closer to each other. 08 move away from the connecting block 501, at this time the diameter of the cleaning rod 508 for cleaning becomes larger, and similarly, when the rotating wheel 510 is rotated in the opposite direction, the cleaning rod 508 will move closer to the connecting block 501, reducing the cleaning diameter. Therefore, the present application can be adapted to the first centrifugal mold 1 or the second centrifugal mold 7 with different diameters, and can be cleaned in different situations, and the side of the cleaning rod 508 contacts the inner wall of the first centrifugal mold 1 or the second centrifugal mold 7. As the cleaning rod 508 rotates, the cleaning work is automatically completed, and the side of the cleaning rod 508 away from the output shaft 4 is in the same plane as the side of the cleaning base plate 502 away from the output shaft 4, as shown in FIG. Figure 1 As shown, when the inner side surface of the first centrifugal mold 1 away from the moving mechanism 2 and the inner side surface of the second centrifugal mold 7 away from the moving mechanism 2 are cleaned, the side surface of the cleaning base 502 away from the output shaft 4 and the side surface of the cleaning rod 508 away from the output shaft 4 will contact the inner side surfaces of the first centrifugal mold 1 and the second centrifugal mold 7, thereby automatically completing the cleaning work, and the position of the cleaning rod 508 can be adjusted. When the cleaning base 502 cleans the center of the inner side surface, the cleaning rod 508 can gradually move away from the cleaning base 502, so as to achieve cleaning of every part of the inner side surface of the first centrifugal mold 1 and the second centrifugal mold 7.

[0026] Reference Figure 6 The moving mechanism 2 includes a support platform 201 for supporting, a servo motor 202 is fixedly connected to the side of the support platform 201, the servo motor 202 is fixedly connected to the side of the support platform 201 close to the threaded rod 203, the side of the threaded rod 203 is threadedly connected to a moving block 204, the top of the moving block 204 is fixedly connected to the bottom end of the rotating motor 3, the top of the moving block 204 is fixedly connected to a support plate 206, the top of the support platform 201 is fixedly connected to the side of the servo motor 202 with a fixed plate 205, the inner side of the fixed plate 205 and the support plate 206 are movably connected to the side of the output shaft 4.

[0027] In the embodiment of the present application, when the threaded rod 203 rotates, the moving block 204 moves. When the moving block 204 moves, the output shaft 4 and the rotating motor 3 are driven to move through the support plate 206. When the output shaft 4 moves, the cleaning rod 508 is driven to move through the connecting block 501. When the rotating motor 3 is started, the cleaning rod 508 is driven to rotate through the output shaft 4. At this time, the cleaning rod 508 rotates and moves in the first centrifugal mold 1 or the second centrifugal mold 7, thereby cleaning the side of the first centrifugal mold 1 or the second centrifugal mold 7. The fixed plate 205 and the support plate 206 can ensure the stability of the output shaft 4 when it moves.

[0028] Reference Figure 1 、 Figure 7 as well as Figure 8 The absorption mechanism 6 includes a connecting cylinder 605 that rotates synchronously with the output shaft 4. The side of the connecting cylinder 605 close to the first centrifugal mold 1 is fixedly connected to the absorption tube 606, and the side of the connecting cylinder 605 away from the first centrifugal mold 1 is movably connected to a rotating ring 607. The bottom and top ends of the rotating ring 607 away from the absorption tube 606 are fixedly connected to the connecting branch pipe 604. The sides of the two connecting branch pipes 604 away from the absorption tube 606 are fixedly connected to the telescopic pipe 603. The side of the telescopic pipe 603 away from the connecting cylinder 605 is fixedly connected to the water-gas dual-purpose pump. 602, the bottom end of the water-gas dual-purpose pump 602 is fixedly connected to the collecting box 601, and the water-gas dual-purpose pump 602 is located in the collecting box 601. The inner side of the rotating ring 607 is movably connected to the inner sealing strip 609, and the outer side of the rotating ring 607 is movably connected to the outer sealing strip 608. The outer sealing strip 608 and the inner sealing strip 609 are both fixedly connected to the connecting tube 605, and when the rotating ring 607 rotates relative to the connecting tube 605, the outer sealing strip 608 and the inner sealing strip 609 prevent liquid leakage, and the telescopic length of the telescopic tube 603 is the same as the moving length of the output shaft 4.

[0029] In the embodiment of the application, the collecting box 601 works in the air extraction mode, and the water-gas dual-purpose pump 602 can absorb gas and liquid, so that the absorption pipe 606 can work normally when it cannot absorb liquid by turning to the upper side, the absorption pipe 606 can suck the cleaning liquid, water and paint cleaned in the first centrifugal mold 1 or the second centrifugal mold 7 into the connecting cylinder 605, and then the cleaning liquid and water cleaned in the first centrifugal mold 1 and the second centrifugal mold 7 are discharged from the water-gas dual-purpose pump 602 to the collecting box 601 through the connecting branch pipe 604 and the telescopic pipe 603, so that the first centrifugal mold 1 and the second centrifugal mold 7 can quickly become dry, the rotating ring 607 rotates relative to the connecting cylinder 605, the inner side and the outer side of the rotating ring 607 are sealed by the inner sealing strip 609 and the outer sealing strip 608, so as to ensure the stability during operation, and when the installation ring 507 works, even if the diameters of the first centrifugal mold 1 and the second centrifugal mold 7 are large, the height of the first centrifugal mold 1 and the second centrifugal mold 7 can be reduced after cleaning, so that the absorption pipe 606 is close to the lower side of the inside of the first centrifugal mold 1 and the second centrifugal mold 7, and then works normally.

[0030] The working principle of the application is as follows: after casting is completed, the first centrifugal mold 1 and the second centrifugal mold 7 are separated, and the processed castings are taken out, when cleaning, the first centrifugal mold 1 or the second centrifugal mold 7 coincides with the axis of the output shaft 4, the cleaning agent and water are added into the first centrifugal mold 1 or the second centrifugal mold 7, the rotating wheel 510 is rotated, the rotating wheel 510 drives the bidirectional screw rod 503 to rotate, the bidirectional screw rod 503 drives the two moving plates 504 to move synchronously inward or synchronously away, when the two moving plates 504 move inward, the connecting plate 505 is rotated, so that the translation plate 506 drives the cleaning rod 508 to move away from the connecting block 501 through the installation ring 507, the two bidirectional screw rods 503 are connected through the gear set 509, so that the two cleaning rods 508 move synchronously away from each other or synchronously move towards each other, and the two cleaning rods 508 are adapted to the inner cavities of the first centrifugal mold 1 or the second centrifugal mold 7 after moving; When the cleaning rod 508 is adapted to the inner cavity of the first centrifugal mold 1 or the second centrifugal mold 7, the servo motor 202 is started and drives the threaded rod 203 to rotate. When the threaded rod 203 rotates, the moving block 204 moves. When the moving block 204 moves, it drives the output shaft 4 and the rotating motor 3 to move through the support plate 206. When the output shaft 4 moves, it drives the cleaning rod 508 to move through the connecting block 501. When the rotating motor 3 is started, it drives the cleaning rod 508 to rotate through the output shaft 4. At this time, the cleaning rod 508 rotates and moves in the first centrifugal mold 1 or the second centrifugal mold 7, thereby The side of the first centrifugal mold 1 or the second centrifugal mold 7 is cleaned, and when the first centrifugal mold 1 is cleaned away from the inside of the rotating motor 3, the cleaning base plate 502 is away from the side of the rotating motor 3 and the cleaning rod 508 is away from the side of the rotating motor 3 and contacts the inside of the first centrifugal mold 1, thereby completing the cleaning of the inside of the first centrifugal mold 1, and similarly the second centrifugal mold 7 is cleaned away from the inside of the rotating motor 3, and the rotatable runner 510 is adjusted to the distance of the cleaning rod 508, ensuring that the first centrifugal mold 1 or the second centrifugal mold 7 are cleaned without omission away from the inside of the rotating motor 3; When the output shaft 4 rotates, the connecting tube 605 and the absorption tube 606 are driven to rotate synchronously, and the rotating ring 607 is fixed by the connecting branch pipe 604, so the rotating ring 607 rotates relative to the connecting tube 605. The inner and outer sides of the rotating ring 607 are sealed by the inner sealing strip 609 and the outer sealing strip 608. Therefore, when the water-gas dual-purpose pump 602 is working, the absorption tube 606 will suck the cleaning liquid, water and the cleaned paint in the first centrifugal mold 1 or the second centrifugal mold 7 into the connecting tube 605, and pass through the connecting branch pipe 604 and the telescopic tube 606. 03 is then discharged from the water-gas dual-purpose pump 602 into the collection box 601, the telescopic tube 603 can be retracted to cooperate with the moving mechanism 2 to drive the movement of the output shaft 4, and the connecting branch pipe 604 and the telescopic tube 603 itself are in a fixed state, so that when the connecting cylinder 605 rotates with the output shaft 4, the rotating ring 607 will not rotate. In addition, it should be noted that fixing the telescopic tube 603 and the connecting branch pipe 604 is a conventional technical means in this field, and this application does not limit its structure. It is sufficient to fix the telescopic tube 603 and the connecting branch pipe 604.

[0031] Finally: The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
