Description

Technical Field

[0001] The utility model relates to the technical field of dental equipment, in particular to a device for preparing a dental cobalt-chromium porcelain composite material. Background Art

[0002] Porcelain fused to steel is a dental technology, generally called porcelain teeth. This kind of restoration has the advantages of high strength of metal, beauty of porcelain, realism of teeth, and wear resistance. It can achieve the ideal function and shape of repairing missing teeth for the repair of missing front teeth and back teeth, improve pronunciation, and make the restoration coordinated with adjacent teeth, lips, occlusion, and facial shape, giving oneself and others a complete and harmonious aesthetic feeling. In addition to repairing missing teeth, this technology can also be used to repair discolored, fluorosis, enamel hypoplasia, cone-shaped and partially defective front teeth. In cases where large-area defects of back teeth cannot be restored after repair, the original appearance of the teeth can also be restored through the technology of porcelain teeth. Cobalt-chromium alloy porcelain teeth are typical non-precious metal porcelain teeth;

[0003] At present, during the casting process of the existing porcelain tooth casting machine, the loading and unloading of the materials is usually performed manually. The truncated cone storage shell containing the wax model is directly placed in the centrifugal position. Although this method is simple to load, it is more troublesome to remove the truncated cone storage shell because the cobalt-chromium alloy needs to be heated and melted by acetylene flame during centrifugal casting, which leads to a high temperature in the entire centrifugal position. Therefore, it is inconvenient to directly remove the truncated cone storage shell manually. Therefore, a preparation device for dental cobalt-chromium porcelain composite materials is proposed.

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0029] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0030] like Figure 1-6 As shown, the dental cobalt-chromium porcelain composite material preparation device proposed by the utility model comprises a casting machine body 1, wherein a driving chamber and a centrifugal casting chamber are arranged inside the casting machine body 1, a driving motor 101 is fixedly arranged at the lower part of the driving chamber, a crucible placement block 2 is fixedly arranged at the output end of the driving motor 101 inside the centrifugal casting chamber, two side baffles 3 are symmetrically fixedly arranged at both ends of the crucible placement block 2, and two angle adjustment components 4 for adjusting a truncated cone-shaped material storage shell 5 are symmetrically arranged between the two side baffles 3;

[0031] The angle adjustment assembly 4 includes a rotating shaft 401 rotatably arranged between the two lateral baffles 3, two driving blocks 402 are symmetrically fixedly arranged in the middle of the rotating shaft 401, and a driven bevel gear 403 is also fixedly arranged in the middle of the rotating shaft 401;

[0032] An L-shaped placement plate 404 is fixedly provided at the upper ends of the two driving blocks 402, and a limiting block 405 for placing the truncated cone-shaped storage shell 5 is fixedly provided on the inner side of the L-shaped placement plate 404;

[0033] Further, the angle adjustment assembly 4 also includes a fixed plate 406 fixed between the two lateral baffles 3, a driving shaft 407 is rotatably provided in the middle of the fixed plate 406, an active bevel gear 408 is fixed at one end of the driving shaft 407 close to the driven bevel gear 403, the active bevel gear 408 and the driven bevel gear 403 are meshed with each other, and a driven gear 409 is fixed at the middle of the other end of the driving shaft 407;

[0034] When the wax pattern is completed, the wax pattern is encapsulated in the interior of the truncated cone storage shell 5. When loading, the truncated cone storage shell 5 is placed inside the limit block 405 using a clamp. At this time, the entire degree adjustment assembly 4 is in an initial state, that is, the openings of the limit blocks 405 inside the two L-shaped placement plates 404 are in a vertical state, thereby facilitating the loading of the truncated cone storage shell 5;

[0035] In the pre-centrifugal casting stage, after the two truncated cone-shaped material storage shells 5 are placed, the two U-shaped limit frames 410 are manually pressed downward to make the U-shaped limit frames 410 move downward, thereby driving the U-shaped driving block 411 to move downward (such as Figure 5 and Figure 6 As shown in the figure, when the U-shaped driving block 411 moves downward, it will drive the driven gear 409 meshing therewith to rotate, and the driven gear 409 rotates to drive the driving shaft 407 to rotate, and the rotation of the driving shaft 407 can drive the active bevel gear 408 to rotate, and further drive the driven bevel gear 403 meshing therewith, thereby realizing the rotation of the rotating shaft 401. As the U-shaped driving block 411 continues to move downward, the L-shaped placement plate 404 is slowly rotated 90°. When the L-shaped placement plate 404 is rotated 90°, the center line of the truncated cone storage shell 5 and the center line of the special-shaped graphite crucible placed inside the crucible placement block 2 are in the same horizontal plane, and centrifugal casting can be started at this time;

[0036] When the center lines of the two truncated cone-shaped material storage shells 5 and the center lines of the two special-shaped graphite crucibles are in the same horizontal plane, the U-shaped limit frame 410 and the lateral baffle 3 are fixedly connected by positioning pins. After the fixation is completed, the drive motor 101 is started, thereby causing the crucible placement block 2, the lateral baffle 3 and the angle adjustment assembly 4 to rotate together, thereby completing the centrifugal casting.

[0037] Furthermore, the angle adjustment assembly 4 also includes two U-shaped limit frames 410 which are symmetrically slidably arranged above the crucible placement block 2 for limiting the sliding of the special-shaped graphite crucible. A U-shaped driving block 411 is fixedly arranged on the inner side of the lower end of the U-shaped limit frame 410 through two connecting rods. A gear block is fixedly arranged on the inner side of the U-shaped driving block 411, and the driven gear 409 can engage with the gear block on the inner side of the U-shaped driving block 411.

[0038] Furthermore, the width of the L-shaped placement plate 404 is smaller than the distance between the two lateral baffles 3 , which facilitates the smooth rotation of the two L-shaped placement plates 404 .

[0039] Furthermore, a partition plate is fixedly provided in the middle of the crucible placing block 2, and the partition plate divides the interior of the crucible placing block 2 into a left placing cavity and a right placing cavity. When two special-shaped graphite crucibles can be placed inside the crucible placing block 2, during centrifugation, the two special-shaped graphite crucibles can respectively exert pressure on the two truncated cone-shaped storage shells 5, thereby improving the casting quality.

[0040] Furthermore, the rotation angle of the L-shaped placement plate 404 is between 0° and 90°, that is, the L-shaped placement plate 404 can be placed vertically or horizontally.

[0041] Furthermore, a rectangular groove is provided in the middle of the two lateral baffles 3 to facilitate the sliding of the U-shaped limiting frame 410 .

[0042] Furthermore, a rectangular groove is provided at the bottom of the crucible placement block 2 to facilitate the sliding of the U-shaped driving block 411 .

[0043] In this embodiment, the placement position of the L-shaped placement plate 404 is adjusted by adjusting the height of the U-shaped limit frame 410, that is, before centrifugal casting, the U-shaped limit frame 410 is in an initial state, which can facilitate the placement of the truncated cone storage shell 5 and two special-shaped graphite crucibles. When the U-shaped limit frame 410 moves downward and is fixed, the center line of the truncated cone storage shell 5 and the center line of the special-shaped graphite crucible can be in the same horizontal plane, which is convenient for centrifugal casting. At the same time, the U-shaped limit frame 410 can also limit the horizontal movement of the special-shaped graphite crucible, thereby ensuring the balance during casting and improving the casting quality.

[0044] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
