[0025] Please see Figure 1-6 This utility model provides a technical solution:

[0026] A mold for controlling the uniform penetration gradient of denture staining solution includes a mold positioning assembly 1, a lower mold assembly 2, and an upper mold assembly 3. The mold positioning assembly 1 includes two positioning posts 11, each with a suction cup 12 fixedly connected to its lower side. Each positioning post 11 has a pair of adjustment grooves 13 on its upper side, with an adjustment plate 14 slidably connected within each groove 13. A first locking block 15 is fixedly connected to the opposite side of each pair of adjustment plates 14, and a first compression spring 16 is fixedly connected inside each first locking block 15. A second locking block 17, fixedly connected to the adjustment plate 14, is located below each first locking block 15, and a second compression spring 18 is fixedly connected inside each second locking block 17. The front side is provided with a lower mold assembly 2, which includes two first positioning plates 21 fixedly connected to the outer side of the positioning post 11. A first mounting bracket 22 is fixedly connected to the front side of the first positioning plate 21. A lower mold 23 of the denture is fixedly connected to the upper side of the fixing protrusion of the first mounting bracket 22. The front side of the mold positioning assembly 1 is provided with an upper mold assembly 3 located above the lower mold assembly 2. The upper mold assembly 3 includes two second positioning plates 31 slidably connected to the outer side of the positioning post 11. A second mounting bracket 32 is fixedly connected to the front side of the second positioning plate 31. A upper mold 33 of the denture is fixedly connected to the lower side of the fixing protrusion of the second mounting bracket 32. A finger retainer plate 34 is fixedly connected to the upper side of the upper mold 33 of the denture.

[0027] Each pair of first locking blocks 15 passes through and is slidably connected to the positioning post 11, and each pair of second locking blocks 17 passes through and is slidably connected to the positioning post 11. The end of the first compression spring 16 furthest from the first locking block 15 passes through the adjusting plate 14 and is fixedly connected to the positioning post 11. The end of the second compression spring 18 furthest from the second locking block 17 passes through the adjusting plate 14 and is fixedly connected to the positioning post 11. The first compression spring 16 and the second compression spring 18 can respectively cause the first locking block 15 and the second locking block 17 to protrude from the positioning post 11. The first mounting bracket 22 and the second mounting bracket 32 are symmetrically distributed. Both the first mounting bracket 22 and the second mounting bracket 32 are curved structures. The front sides of both the first mounting bracket 22 and the second mounting bracket 32 are provided with multiple evenly distributed fixing protrusions. The first mounting bracket 22 and the second mounting bracket 32 can be used to install and fix the lower mold 23 and the upper mold 33 of the denture, respectively. The first positioning plate 21 and the second positioning plate 31 are symmetrically distributed, and the lower mold 23 and the upper mold 33 of the denture correspond one-to-one. The lower mold 23 and the upper mold 33 of the denture are provided with openings on their opposite sides, and each side of the lower mold 23 and the upper mold 33 of the denture is provided with openings. The denture to be stained can be loaded and positioned through the lower mold 23 and the upper mold 33 of the denture. The inner side of the second positioning plate 31 is provided with two locking grooves that match the first locking block 15. The first locking block 15 and the second locking block 17 have the same shape. The second positioning plate 31 can be locked at different heights of the positioning post 11 through the first locking block 15 and the second locking block 17, respectively.

[0028] Workflow: This device is an auxiliary mechanism used in conjunction with a denture staining device. When not in use, the second positioning plate 31 is locked by the first locking block 15, and the first compression spring 16 and the second compression spring 18 are in a slightly compressed state. There is a gap between the lower denture mold 23 and the upper denture mold 33. When the device is needed, the operator first checks whether all components of the device are intact and connects the power supply to the denture staining device. Then, the operator places the denture to be stained into the matching lower denture mold 23. The arrangement and number of the lower denture molds 23 are consistent with the arrangement and number of human teeth, thus allowing for denture positioning. The operator then pinches the two pairs of adjusting plates 14, bringing them closer together. The adjusting plates 14 in the adjusting groove 13 then move the pairs of first locking blocks 15 and second locking blocks 17 closer together, further compressing the first compression spring 16 and the second compression spring 18. This releases the first locking block 15 from locking the second positioning plate 31. The operator then pushes the second positioning plate 31 downwards, causing it to slide down along the positioning post 11. Releasing the adjusting plates 14 allows the second positioning plate 31 to move the second mounting bracket 32 and the upper mold of the denture downwards, and the second locking block 17 returns to its original position. 7. Lock the second positioning plate 31. Since the lower denture mold 23 is fixed at the designated height of the positioning post 11 by the first positioning plate 21 and the first mounting bracket 22, the lowered upper denture mold 33 can fit against the upper side of the lower denture mold 23. The lower denture mold 23 and the upper denture mold 33 can restrict the denture to be stained. Then, the worker lifts the device with the finger clamp 34, places the device in the staining box of the denture staining device, and attaches the suction cup 12 to the bottom of the staining box to fix the device. The denture staining device can then be started to perform staining. The device can be separated by the first mounting bracket 22 and the second mounting bracket 32. Do not install and fix the lower mold 23 and upper mold 33 of the denture. The lower mold 23 and upper mold 33 of the denture can be used to load and position the denture to be stained. The second positioning plate 31 is locked at different heights of the positioning post 11 by the first locking block 15 and the second locking block 17 respectively, so as to prevent the denture from detaching from the lower mold 23 and the upper mold 33 of the denture. This device can load multiple dentures at one time and limit the dentures one by one to prevent collision between dentures and damage. It can also accurately position and identify dentures. After staining, the staff does not need to distinguish dentures in different positions, which saves time and effort.
