Description

Technical Field

[0001] This utility model relates to the field of water bath heating curing box technology, and in particular to a curing device for denture resin base. Background Technology

[0002] Water bath curing chambers are often used for curing resin denture bases. A water bath curing chamber is a special heat treatment device for denture fabrication. Its core principle is to completely immerse the resin-filled plaster model of the denture in a constant temperature water tank. By programmatically controlling the water temperature, indirect and uniform heating and curing of the resin base are achieved. This process can effectively reduce internal stress and air bubbles caused by excessively rapid heating or uneven heating, thereby improving the dimensional stability, mechanical strength, and accuracy and quality of the final restoration. It is a key step in traditional denture fabrication.

[0003] However, the existing water bath heating curing box has a relatively simple device for placing the denture boiling box. During operation or when subjected to slight vibration, the boiling box is prone to movement or misalignment. Furthermore, the water bath heating mainly relies on the natural convection of water and the heating of the resistance rod. This method results in uneven heat distribution and a large water temperature gradient, which leads to uneven heating of the resin base, affecting the curing quality, and the heating speed is relatively slow.

[0004] Therefore, we propose a curing device for denture resin bases to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A curing device for denture resin bases includes a water bath curing chamber. Fixed bases are fixedly installed on both inner walls of the water bath curing chamber. Multiple placement rods are fixedly installed on the side of the two fixed bases that are close to each other. Two driven sliders are slidably installed on the top of each of the two fixed bases. A common positioning rod is fixedly installed on the side of the two driven sliders that are close to each other on the same side. A stirring shell is fixedly installed on one side of the water bath curing chamber. A stirring chamber is formed inside the stirring shell. Two drive shafts are rotatably installed on the inner wall of one side of the water bath curing chamber, and the other ends of the two drive shafts rotatably extend into the stirring chamber.

[0007] Specifically, the top of the water bath heating curing chamber is hinged and fitted with a top cover, and an observation window is provided on the top of the top cover. The interior of the water bath heating curing chamber has multiple heating chambers, and resistance heating rods are fixedly installed on the inner side of each heating chamber. The observation window can help operators monitor the curing process or water level without opening the top cover or disturbing the internal temperature environment.

[0008] Specifically, a positioning shaft is rotatably mounted on the top of each of the two fixed bases, and a rhomboid positioning block is fixedly sleeved on the outer side of each of the two positioning shafts. Two linkage shafts are fixedly mounted on the top of each of the two rhomboid positioning blocks, and cranks are rotatably sleeved on each of the four linkage shafts. A driven shaft is fixedly mounted on the top of each of the four driven sliders, and the four cranks are respectively hinged to the corresponding driven shafts. This enables synchronous and smooth clamping and releasing actions, with uniform clamping force, avoiding inconsistencies caused by manual operation.

[0009] Specifically, each of the two fixed bases has a motor slot inside, and a positioning servo motor is fixedly installed on the bottom inner wall of each of the two motor slots. The output shafts of the two positioning servo motors are fixedly connected to the corresponding positioning shafts. Each of the two fixed bases has two inclined vent holes at the bottom, and the four inclined vent holes are connected to the corresponding motor slots. The inclined vent holes are used for heat dissipation of the motor slots and to prevent water vapor condensation, ensuring the long-term stable operation of the positioning servo motors in humid environments.

[0010] Specifically, the same denture simmering box is placed on multiple storage rods, and two positioning rods abut against the same denture simmering box to facilitate fixing the denture simmering box and prevent it from moving or becoming misaligned.

[0011] Specifically, a heat dissipation vent is provided on one side of the stirring shell, which is connected to the stirring chamber. A stirring servo motor is fixedly installed on the bottom inner wall of the heat dissipation vent, and a double row of drive wheels is fixedly sleeved on the output shaft of the stirring servo motor. A dust filter is fixedly installed on the inner side of the heat dissipation vent. The dust filter can ensure stable heat dissipation of the stirring servo motor and prevent external dust from entering the heat dissipation vent.

[0012] Specifically, a slow-speed reverse wheel and a fast-speed forward wheel are fixedly fitted onto one end of each of the two drive shafts that extend into the mixing chamber. The same cross belt is wound between the double-row drive wheel and the slow-speed reverse wheel, and the same drive belt is wound between the double-row drive wheel and the fast-speed forward wheel. The diameter of the slow-speed reverse wheel is larger than that of the fast-speed forward wheel, which can realize bidirectional different-speed mixing of the two drive shafts, thereby creating a complex, efficient and shear-force-rich flow field.

[0013] Specifically, multiple stirring blades are fixedly mounted on the two drive shafts. The multiple stirring blades on the two drive shafts rotate at different speeds and in opposite directions, which can form complex turbulent and shear flow in the water bath heating curing box. This flow field can greatly enhance the mixing efficiency of the fluid, completely disrupt and eliminate temperature stratification, and achieve a temperature uniformity effect far exceeding that of co-directional stirring.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting up a positioning servo motor-driven positioning shaft, linkage shaft, crank, and driven slider, the two positioning rods are brought close to each other, precisely clamping and fixing the denture boiling box from both sides, ensuring the stability and safety of the curing process. Furthermore, the two drive shafts perform bidirectional high-speed stirring, creating a flow field full of shear force and complex turbulence, which can greatly destroy the thermal boundary layer, making the water temperature in the tank highly uniform and greatly improving the heat transfer efficiency. At the same time, it can ensure that all parts of the denture boiling box are heated evenly, thereby improving the quality and efficiency of curing. Attached Figure Description

[0023] In this embodiment, a positioning shaft 7 is rotatably mounted on the top of each of the two fixed bases 4, and a rhomboid positioning block 8 is fixedly sleeved on the outer side of each of the two positioning shafts 7. Two linkage shafts 9 are fixedly mounted on the top of each of the two rhomboid positioning blocks 8, and cranks 10 are rotatably sleeved on each of the four linkage shafts 9. A driven shaft 11 is fixedly mounted on the top of each of the four driven sliders 12. The four cranks 10 are respectively hinged to the corresponding driven shafts 11, which can realize synchronous and stable clamping and releasing actions, uniform clamping force, and avoid inconsistencies in manual operation.

[0024] In this embodiment, motor slots are provided inside both fixed bases 4, and positioning servo motors 6 are fixedly installed on the bottom inner walls of both motor slots. The output shafts of the two positioning servo motors 6 are respectively fixedly connected to the corresponding positioning shafts 7. Two inclined vent holes are provided at the bottom of both fixed bases 4, and the four inclined vent holes are respectively connected to the corresponding motor slots. The inclined vent holes are used for heat dissipation of the motor slots and to prevent water vapor condensation, so as to ensure the long-term stable operation of the positioning servo motors 6 in humid environments.

[0025] In this embodiment, the same denture cooking box 14 is placed on multiple placement rods 5, and two positioning rods 13 abut against the same denture cooking box 14 to facilitate fixing the denture cooking box 14 and prevent it from moving or being misaligned.

[0026] In this embodiment, a heat dissipation vent is provided on one side of the stirring shell 15, which is connected to the stirring chamber. A stirring servo motor 17 is fixedly installed on the bottom inner wall of the heat dissipation vent. A double row of drive wheels 18 is fixedly sleeved on the output shaft of the stirring servo motor 17. A dust filter 16 is fixedly installed on the inner side of the heat dissipation vent. The dust filter 16 can ensure stable heat dissipation of the stirring servo motor 17 and prevent external dust from entering the heat dissipation vent.

[0027] In this embodiment, a slow-speed reverse wheel 19 and a fast-speed forward wheel 21 are respectively fixedly sleeved on one end of the two drive shafts 23 extending into the mixing chamber. The same cross belt 20 is wound between the double-row drive wheel 18 and the slow-speed reverse wheel 19, and the same drive belt 22 is wound between the double-row drive wheel 18 and the fast-speed forward wheel 21. The diameter of the slow-speed reverse wheel 19 is larger than the diameter of the fast-speed forward wheel 21, which can realize bidirectional different-speed mixing of the two drive shafts 23, thereby creating a complex, efficient and shear-force-rich flow field.

[0028] In this embodiment, multiple stirring blades 24 are fixedly mounted on the two drive shafts 23. The multiple stirring blades 24 on the two drive shafts 23 rotate at different speeds and in opposite directions, which can form complex turbulent and shear flow in the water bath heating curing box 1. This flow field can greatly enhance the mixing efficiency of the fluid, completely disrupt and eliminate temperature stratification, and achieve a temperature uniformity effect far exceeding that of unidirectional stirring.

[0029] Working Principle: During the curing of the denture resin base, the operator places the resin-filled mold into the denture curing box 14, seals it, and places it on multiple placement rods 5. Then, two positioning servo motors 6 with identical parameters are activated. The activation of these two servo motors drives the corresponding positioning shafts 7 to rotate. The rotation of the two positioning shafts 7 drives the corresponding two linkage shafts 9 to move around the positioning shafts 7 as the center. The movement of the four linkage shafts 9 drives the corresponding cranks 10 to move, which in turn drives the corresponding driven shafts 11 to move. The movement of the four driven shafts 11 drives the corresponding driven sliders 12 to move. A positioning rod 13 is fixedly installed between the two driven sliders 12 on the same side. The two positioning rods 13 are brought close together, thus positioning and fixing the denture curing box 14 to prevent displacement during the curing process. Then, the operator adds water to the water bath curing chamber 1 until the water level covers the denture curing box 14 and closes the chamber. The top cover 2 activates the stirring servo motor 17 and multiple resistance heating rods 3, which heat the water. The stirring servo motor 17 drives the double-row drive wheel 18 to rotate. The double-row drive wheel 18 drives the slow reverse wheel 19 and the fast forward wheel 21 to rotate via the cross belt 20 and the transmission belt 22, respectively. The diameter of the slow reverse wheel 19 is larger than that of the fast forward wheel 21, so the speed of the slow reverse wheel 19 is lower than that of the fast forward wheel 21. At the same time, the cross belt 20 drives the slow reverse wheel 19 to rotate counterclockwise, and the transmission belt 22 drives the fast forward wheel 21 to rotate clockwise. The slow reverse wheel 19 and the fast forward wheel 21 rotate in opposite directions. The slow reverse wheel 19 and the fast forward wheel 21 drive the corresponding transmission shaft 23 to rotate together with multiple stirring blades 24, thereby achieving bidirectional variable speed stirring, creating a complex, efficient and shear-force-rich flow field, maximizing the convective heat transfer efficiency, and accelerating the curing of the denture resin base.

[0030] The technological advancements of this invention compared to existing technologies are as follows: the denture curing box 14 can be precisely clamped and fixed from both sides, ensuring the stability and safety of the curing process. Furthermore, the bidirectional, variable-speed stirring via two drive shafts 23 creates a flow field full of shear force and complex turbulence, which can greatly disrupt the thermal boundary layer, making the water temperature in the water bath curing chamber 1 highly uniform and significantly improving heat transfer efficiency. At the same time, it can ensure that all parts of the denture curing box 14 are heated evenly, thereby improving the quality and efficiency of curing.
