Description

Technical Field

[0001] This utility model belongs to the field of denture box technology, specifically relating to a denture box and its assembly / disassembly device. Background Technology

[0002] Dentures, commonly known as false teeth, refer to teeth that serve a human function. Medically, they are a general term for restorations made after partial or complete loss of the upper and lower jaw teeth. The fabrication of dentures requires a denture mold. Existing denture molds include an upper mold and a lower mold. The inner cavity of the upper mold fits the upper part of the denture, and the inner cavity of the lower mold fits the lower part of the denture. During denture fabrication, the denture wax model is placed in the denture mold, and then the upper and lower molds are pressed together to ensure tight contact and improve the yield rate. However, existing molds have the defect of incomplete pressing, resulting in a low yield rate. Furthermore, after the denture mold is extruded, the large extrusion force applied makes demolding and separating the upper and lower molds difficult. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a denture box and a disassembly and assembly device.

[0004] The specific plan is as follows:

[0005] A denture housing includes an upper housing and a lower housing, which are detachably connected. A first connecting plate is evenly distributed along the bottom edge of the upper housing, and a second connecting plate is evenly distributed along the top edge of the lower housing. Screw mounting holes are provided at corresponding positions on the first and second connecting plates, and the first and second connecting plates are detachably connected through the screw mounting holes. A snap-fit ​​groove is also provided on the end of the first connecting plate away from the upper housing, and the snap-fit ​​groove is fixed to the first connecting plate.

[0006] The bottom of the upper mold box is evenly provided with positioning posts, and the top of the lower mold box is provided with positioning holes that cooperate with the positioning posts.

[0007] A third connecting plate is also provided at the bottom edge of the lower mold box, and the third connecting plate is evenly fixed to the bottom edge of the lower mold box.

[0008] The bottom of the lower mold box is also provided with a demolding through hole and a gasket, with the gasket placed on the demolding through hole.

[0009] A disassembly and assembly device is used for disassembling and assembling a denture box. The device includes a worktable and a synchronous lifting linkage. The synchronous lifting linkage is slidably connected to the surface of the worktable. The synchronous lifting linkage includes a drive unit, a support plate, and connecting rods. The number of connecting rods is the same as the number of first connecting plates on the upper denture box. One end of each connecting rod is fixed to the support plate. The support plate is fixedly connected to the output shaft of the drive unit. The other end of each connecting rod is provided with a snap-fit ​​unit. The snap-fit ​​unit is movably sleeved with the connecting rod, and the snap-fit ​​unit can be snapped into a snap-fit ​​groove.

[0010] The workbench is provided with a table surface through hole that matches the demolding through hole, and the positions of the table surface through hole correspond to each other. A demolding top post is also fixedly installed on the support plate, and the distance between the top of the demolding top post and the bottom surface of the workbench is equal to the height of the upper mold box.

[0011] The connecting rod is also provided with a first pin and a second pin, and the connecting rod is provided with a pin hole. The first pin and the second pin are both pluggably connected to the connecting rod through the pin hole. The snap-fit ​​unit is movably sleeved between the first pin and the second pin.

[0012] The snap-fit ​​unit includes a sleeve, which is located between the first pin and the second pin and is movably sleeved with the connecting rod. A first snap-fit ​​block and a second snap-fit ​​block are fixedly provided at both ends of the sleeve, the first snap-fit ​​block is an inverted L-shaped snap-fit ​​block and the second snap-fit ​​block is an L-shaped snap-fit ​​block. The first snap-fit ​​block and the second snap-fit ​​block are symmetrically fixed at both ends of the sleeve, and both the first snap-fit ​​block and the second snap-fit ​​block can snap-fit ​​with the snap-fit ​​groove.

[0013] The drive unit is a hydraulic cylinder, a pneumatic cylinder, or an electric push rod.

[0014] The workbench surface is provided with through holes, and the synchronous lifting linkage is slidably connected to the workbench surface through the through holes.

[0015] The third connecting plate is provided with a fixing screw hole, and the workbench surface is also provided with a threaded hole that matches the fixing screw hole. The threaded hole is a blind hole.

[0036] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the implementation of this utility model, not all of it. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0037] like Figures 1 to 3 As shown, a denture box includes an upper box 1 and a lower box 8, which are detachably connected. The lower box 1 has a first connecting plate 2 evenly distributed on its bottom edge, and the lower box 8 has a second connecting plate 6 evenly distributed on its top edge. Screw mounting holes 5 are provided at corresponding positions on the first connecting plate 2 and the second connecting plate 6. The first connecting plate 2 and the second connecting plate 6 are detachably connected through the screw mounting holes 5. A snap-fit ​​groove 4 is also provided on the first connecting plate 2 at the end away from the upper box 1, and the snap-fit ​​groove 4 is fixed to the first connecting plate 2.

[0038] The upper molded box 1 is provided with positioning posts 3 evenly distributed at the bottom end, and the lower molded box 8 is provided with positioning holes 7 that cooperate with the positioning posts 3 at the top end.

[0039] The bottom edge of the lower mold box 8 is also provided with a third connecting plate 9, which is evenly fixed to the bottom edge of the lower mold box 8.

[0040] like Figures 3 to 4 As shown, the bottom of the lower mold box 8 is also provided with a demolding through hole 25 and a gasket 24, with the gasket 24 placed on the demolding through hole 25.

[0041] like Figures 5 to 6As shown, a disassembly and assembly device is used for disassembling and assembling the aforementioned denture box. The device includes a worktable 11 and a synchronous lifting linkage 12. The synchronous lifting linkage 12 is slidably connected to the surface of the worktable 11. The synchronous lifting linkage 12 includes a drive unit 13, a support plate 14, and connecting rods 15. The number of connecting rods 15 is the same as the number of first connecting plates 2 on the upper denture box 1. One end of each connecting rod 15 is fixed to the support plate 14, which is fixedly connected to the output shaft of the drive unit 13. A snap-fit ​​unit 16 is provided at the other end of each connecting rod 15. The snap-fit ​​unit 16 is movably sleeved with the connecting rod 15, and can be snap-fitted into a snap-fit ​​groove 4.

[0042] The workbench 11 is provided with a table surface through hole 26 that matches the demolding through hole 25. The positions of the table surface through hole 26 correspond to each other. A demolding top post 27 is also fixedly provided on the support plate 14. The distance between the top of the demolding top post 27 and the bottom surface of the workbench 11 is equal to the height of the upper mold box 1.

[0043] In this embodiment, the drive unit 13 drives the lifting and lowering of the carrier plate 14, thereby causing the connecting rod 15, which is fixedly connected to the carrier plate 14, to lift and lower synchronously, and the demolding top column 27 also lifts and lowers synchronously with the carrier plate 14.

[0044] like Figure 6 As shown, the connecting rod 15 is also provided with a first pin 21 and a second pin 22. The connecting rod 15 is provided with a pin hole. The first pin 21 and the second pin 22 are both pluggably connected to the connecting rod 15 through the pin hole. The snap-fit ​​unit 16 is movably sleeved between the first pin 21 and the second pin 22.

[0045] The snap-fit ​​unit 16 includes a sleeve 18, which is located between the first pin 21 and the second pin 22 and is movably sleeved with the connecting rod 15. The two ends of the sleeve 18 are respectively fixedly provided with a first snap-fit ​​block 17 and a second snap-fit ​​block 19. The first snap-fit ​​block 17 is an inverted L-shaped snap-fit ​​block, and the second snap-fit ​​block 19 is an L-shaped snap-fit ​​block. The first snap-fit ​​block 17 and the second snap-fit ​​block 19 are symmetrically fixed at both ends of the sleeve 18. Both the first snap-fit ​​block 17 and the second snap-fit ​​block 19 can snap-fit ​​with the snap-fit ​​groove 4.

[0046] Since the first locking block 17 and the second locking block 19 are fixedly connected to the sleeve 18, and the sleeve 18 is sleeved with the connecting rod 15, the sleeve 18 can be manually rotated on the connecting rod 15. The rotation of the sleeve 18 will drive the first locking block 17 and the second locking block 19 to rotate as well. The rotation of the first locking block 17 and the second locking block 19 is to facilitate the placement of the lower mold box 8 and the upper mold box 1 on the worktable 11.

[0047] The drive unit 13 is a hydraulic cylinder, a pneumatic cylinder, or an electric push rod.

[0048] The workbench 11 has a through hole on its surface, and the synchronous lifting linkage 12 is slidably connected to the workbench 11 surface through the through hole.

[0049] The third connecting plate 9 is provided with a fixing screw hole 10, and the workbench 11 is also provided with a threaded hole 20 that matches the fixing screw hole 10. The threaded hole 20 is a blind hole. The lower mold box 8 can be fixed on the workbench 11 by the cooperation of the threaded hole 20 and the fixing screw hole 10.

[0050] The specific working process of the denture box and disassembly / assembly device is as follows:

[0051] like Figure 7 As shown, before placing the upper mold box 1 and the lower mold box 8 onto the worktable 11, the locking unit 16 on each connecting rod 15 is rotated, causing the end of the first locking block 17 not connected to the sleeve 18 to rotate towards the edge of the worktable 11. This prevents the first locking block 17 and the second locking block 19 from interfering with the placement of the upper mold box 1 and the lower mold box 8. Since both the first locking block 17 and the second locking block 19 are fixed to the sleeve 18, the second locking block 19 rotates simultaneously with the first locking block 17. Figure 5 This is a schematic diagram of the snap-fit ​​unit 16 when it is not rotating. Figure 7 A schematic diagram of the timing card unit 16 after rotation.

[0052] like Figure 8 As shown, after the snap-fit ​​unit 16 rotates, the lower mold box 8 is placed on the worktable 11. The position of the lower mold box 8 on the worktable 11 is adjusted so that the fixing screw hole 10 on the third connecting plate 9 corresponds to the threaded hole 20 on the worktable 11. The lower mold box 8 is fixed on the worktable 11 by screws 23. At the same time, the gasket 24 is placed on the demolding through hole 25 to block the demolding through hole 25. Then, the denture wax pattern is placed in the lower mold box 8.

[0053] like Figure 9 As shown, the positioning pin 3 of the upper mold box 1 is aligned with the positioning hole on the lower mold box 8, and the first connecting plate 2 in the upper mold box 1 and the second connecting plate 6 in the lower mold box 8 are connected by screws and nuts through the screw mounting holes 5. At this time, the first connecting plate 2 and the second connecting plate 6 are connected together, and the upper mold box 1 and the lower mold box 8 complete the initial positioning.

[0054] like Figures 10 to 11As shown, after the upper mold box 1 and the lower mold box 8 have completed the initial positioning, the operation drive unit 13 drives the carrier plate 14 to rise. The carrier plate 14 drives each connecting rod 15 to rise synchronously. The connecting rod 15 continues to rise. When the first locking block 17 exceeds the first connecting plate 2 and the second locking block 19 does not exceed the second connecting plate 2, the drive unit 13 stops working. At this time, the connecting rod 15 stops rising. The first locking block 17 on each connecting rod 15 is rotated manually so that the first locking block 17 and the locking groove 4 of the first connecting plate 2 can be locked in place.

[0055] During the upward movement of the connecting rod 15, the demolding ejector pin 27 also rises synchronously. However, since the distance between the top of the demolding ejector pin 27 and the bottom surface of the worktable 11 is equal to the height of the upper mold box 1, although the demolding ejector pin 27 has risen, it still does not contact the gasket 24 inside the lower mold box 8, and therefore will not lift the gasket 24 inside the lower mold box 8.

[0056] like Figure 12 As shown, after the rotation is completed, the operation drive unit 13 drives the bearing plate 14 to descend, and the connecting rod 15 descends synchronously, so that the first locking block 17 engages with the locking groove 4 of the first connecting plate 2. The connecting rod 15 continues to descend, and the first locking block 17 applies a downward pulling force to the upper mold box 1. After the connecting rod 15 can no longer descend under the action of the drive unit 13, the screws on the first connecting plate 2 are tightened again by using a wrench, so that the upper mold box 1 and the lower mold box 2 are closely connected. In this embodiment, the downward driving force of the drive unit is controlled within a certain range and will not damage the mold box and the worktable.

[0057] like Figure 13 As shown, during the demolding process of the denture box, the screws on the first connecting plate 2 are removed by wrench, and the drive unit 13 is operated again to make the drive bearing plate 14 rise, and the connecting rod 15 rises accordingly. During the rise of the connecting rod 15, the first locking block 17 leaves the locking groove 4. As the connecting rod 15 continues to rise, the second locking block 19 engages with the locking groove 4. Subsequently, the second locking block 19 can lift the upper mold box 1 through the locking groove 4.

[0058] As connecting rod 15 rises, demolding ejector pin 27 also rises synchronously with connecting rod 15. When the height to which connecting rod 15 lifts the upper mold box 1 is equal to the height of the upper mold box 1 itself, the demolding ejector pin 27 contacts the gasket 24 in the lower mold box 8, and the upper mold box 1 and the lower mold box 8 are completely separated. Then, connecting rod drive unit 13 drives the bearing plate 14 to rise further, and the demolding ejector pin 27 rises accordingly, lifting the gasket 24 from the lower mold box 1. In this way, the formed denture is also lifted along with the gasket 24. Figure 14 As shown, this facilitates the separation of the molded denture from the lower molded box 8.

[0059] Finally, remove the finished denture from the lower mold box 8, remove the screws at the third connecting plate 9 in the lower mold box 8, and remove the lower mold box 8 from the workbench 11 to complete the demolding.

[0060] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
