Description

Technical Field

[0001] This invention relates to the field of casting mold technology for disc seats, specifically a casting mold for a vertical mill disc seat and a method for using the mold. Background Technology

[0002] Vertical mills are grinding equipment that integrates fine crushing, drying, grinding, powder selection, and conveying. They are widely used in the grinding and ultrafine grinding of various solid materials in industries such as cement, building materials, power, metallurgy, chemical, and non-metallic minerals. The grinding process of a vertical mill is completed by a set of grinding devices (i.e., grinding rollers and grinding discs). The material is ground into powder between the grinding rollers and the grinding discs. The movement of the grinding device is driven by the rotation of the grinding discs, which in turn drives the grinding rollers. In addition to the weight of the grinding rollers themselves, the grinding pressure is mainly achieved by a hydraulic device that pressurizes the material on the grinding discs. The material after grinding contains a large amount of coarse powder, which is then separated by a matching powder classifier. The powder separation process involves airflow separation. During the airflow process, most of the coarse powder automatically falls onto the grinding discs for further grinding. The remainder is separated by the powder classifiers and sent to the finished product storage silo via a dust collection and conveying system.

[0003] When producing a vertical mill, the internal disc seat needs to be cast. However, during the casting process, the mold is closed and the material is injected into the mold for casting. Due to the large size and heavy weight of the disc seat, and the fact that the disc seat is located inside the mold, it is inconvenient to remove the disc seat from the mold for movement. In order to facilitate the movement of the disc seat out of the mold, a vertical mill disc seat casting mold and a method for using the mold are provided. Summary of the Invention

The upper mold is located above the lower mold.

[0017] Step 2: Start the hydraulic cylinder. The hydraulic cylinder drives the upper mold to move downward along the guide rod to close the mold. When the upper mold and the lower mold are closed, the connecting rod is inserted into the guide hole to reinforce the position of the connecting seat. The upper mold pushes the vertical block to move, which drives the moving column to move and insert into the circular groove, forming the inner cavity of the circular groove into a ring shape.

[0032] Please see Figures 1 to 8In this embodiment of the invention, a vertical mill disc base casting mold includes a base 1, an upper mold 3 and a lower mold are arranged above the base 1, the lower mold is composed of four connecting seats 2 spliced ​​together, the outer wall of the upper mold 3 is provided with a material injection port 7, the connecting seats 2 are moved and spliced ​​by a splicing mechanism 4, the upper mold 3 is moved by a docking mechanism 5, and the ring on the disc base is formed by an adjusting mechanism 6; the splicing mechanism 4 includes a movable plate 401, the movable plate 401 is fixedly connected to the bottom end of the connecting seat 2, and the top end of the base 1 is provided with a movable plate 401. The movable groove 402 allows the movable plate 401 to slide. The base 1 is rotatably connected to a threaded rod 403 that passes through the movable plate 401. One end of the threaded rod 403 is fixedly connected to a bevel gear 404. The base 1 is rotatably connected to a gear ring 405 located on the outer wall of the bevel gear 404. A mounting plate 406 is fixedly connected to one side of the outer wall of the base 1. A motor 407 is mounted on the outer wall of the mounting plate 406. The output end of the motor 407 is connected to a spur gear 408, which contacts the gear ring 405.

[0033] In this embodiment: when the connecting seat 2 is moved, the motor 407 is started. The motor 407 drives the spur gear 408 to rotate. The rotation of the spur gear 408 drives the gear ring 405 to rotate. The rotation of the gear ring 405 drives the bevel gear 404 to rotate. The rotation of the bevel gear 404 drives the threaded rod 403 to rotate. The rotation of the threaded rod 403 drives the movable plate 401 to slide in the movable groove 402. The sliding of the movable plate 401 drives the connecting seat 2 to move. Multiple connecting seats 2 contact each other to complete the splicing of the lower mold.

[0034] Please refer to this carefully. Figures 2 to 6 The docking mechanism 5 includes a sliding groove 501, which is symmetrically opened at the top of the base 1. The inner wall of the sliding groove 501 is slidably connected to the mounting bracket 502. The outer wall of the mounting bracket 502 is equipped with a hydraulic cylinder 503. The upper mold 3 is connected to the output end of the hydraulic cylinder 503. The outer wall of the mounting bracket 502 is fixedly connected to a guide rod 504 that passes through the upper mold 3. The outer wall of the upper mold 3 is provided with a guide hole 505 for the guide rod 504 to pass through. The top of the connecting seat 2 is fixedly connected to a docking rod 506. One end of the mounting bracket 502 is fixedly connected to a connecting bracket 507. The bottom end of the connecting bracket 507 is fixedly connected to a toothed plate 508, which contacts the spur gear 408.

[0035] In this embodiment: when the spur gear 408 rotates and drives the connecting seats 2 to approach each other for splicing, the rotation of the spur gear 408 drives the toothed plate 508 to move. The displacement of the toothed plate 508 drives the connecting frame 507 to move. The movement of the connecting frame 507 drives the mounting frame 502 to slide in the slide groove 501. After the connecting seats 2 are spliced, the upper mold 3 moves above the connecting seats 2. At this time, the hydraulic cylinder 503 is activated. The operation of the hydraulic cylinder 503 drives the upper mold 3 to move downward along the guide rod 504 to close the mold. When the upper mold 3 and the lower mold are closed, the mating rod 506 is inserted into the guide hole 505 to reinforce the position of the connecting seats 2.

[0036] Please refer to this carefully. Figures 6 to 8 The adjusting mechanism 6 includes a circular groove 601, which is opened on both sides of the connecting seat 2.

A vertical block 606 is fixedly connected to the top end of the displacement plate 604. The vertical block 606 extends above the connecting seat 2 and is located on one side of the connecting rod 506.

[0037] In this embodiment: when the upper mold 3 and the lower mold are closed, the upper mold 3 contacts the vertical block 606, pushing the vertical block 606 to move. The movement of the vertical block 606 causes the displacement plate 604 to move, which compresses the spring 605. The movement of the displacement plate 604 drives the moving column 602 to move into the inner cavity of the circular groove 601 through the connecting rod 603, forming the inner cavity of the circular groove 601 into a ring shape. The ring on the plate is formed in the circular groove 601.

[0038] When the upper mold 3 moves away from the lower mold, the displacement plate 604 is reset by the elastic force of the spring 605. The displacement plate 604 drives the moving column 602 to move through the connecting rod 603. The moving column 602 moves out of the circular groove 601 to prevent the moving column 602 from blocking the movement of the connecting seat 2 when the connecting seat 2 is separated, so as to facilitate the direct forming of the ring on the plate.

[0039] The lower mold is set up to be composed of four connecting seats 2 spliced ​​together. When demolding, the four connecting seats 2 move away from each other, and the plate base is directly separated from the lower mold. At the same time, when separating, the mounting bracket 502 moves and drives the upper mold 3 to move away from the plate base automatically, exposing the top of the plate base, which facilitates the demolding operation of the plate base and makes it convenient to move the plate base in the future.
