Abstract
Description
Technical Field
[0001] This application relates to the field of dental prosthesis fabrication technology, specifically a mold box for casting dental paraffin models. Background Technology
[0002] The first step in denture fabrication is creating a wax model. Technicians use 3D printing or hand carving techniques to create a wax model of the denture based on the size and shape of the patient's oral impression. This wax model serves as the basis for subsequent denture fabrication. The wax model is then placed in a mold box, which is filled with plaster to form a cavity. Once the plaster has solidified and the cavity is stable, the entire mold box, along with the plaster mold box and the wax model, is placed in boiling water. The wax melts and flows out, and then denture-specific materials are poured into the plaster model to form the denture.
[0003] However, when using existing mold boxes, the lack of fixing devices between the various components leads to unstable connections between the components, which may cause more wear and damage during long-term use, resulting in increased errors and a shortened overall lifespan of the equipment. Utility Model Content
[0004] To address the shortcomings of existing technologies, this application provides a mold box for dental paraffin model casting, which has advantages such as reducing errors. It solves the problem that when existing mold boxes are used, the unstable connection between the components due to the lack of fixing devices may lead to more wear and damage during long-term use, resulting in increased errors and shortening the overall lifespan of the equipment.
[0005] To achieve the above objectives, this application provides the following technical solution: a mold box for casting dental paraffin models, comprising a molding device, a feeding device, a mounting post, and a base plate. The molding device includes two mold boxes, each with a mounting strip fixedly connected to one side. Threaded holes are provided at the upper ends of the two mold boxes. A support rod is fixedly connected to one side of the mounting post. Four fixing pins arranged in a circular array are fixedly connected to the end of the support rod away from the mounting post. The feeding device includes a dental prosthesis material container. A movable sealing plate is slidably connected inside the dental prosthesis material container. A threaded tube is fixedly connected to the bottom end of the dental prosthesis material container. Two mounting seats arranged in a mirror image are fixedly connected to the upper end of the base plate.
[0006] The molding device, as described above, consists of two mold boxes connected to mounting bases on the base plate via mounting strips. This design enhances the overall structural stability and helps maintain the mold boxes' fixation and positional accuracy during the molding process. The mounting post connects to the mold boxes via threaded holes, securing the wax model between the two mold boxes and ensuring its stability and precision during molding. The dental prosthesis material container in the feeding device is equipped with a movable sealing plate and a threaded tube. The movable sealing plate controls the injection volume of the dental prosthesis material, while the threaded tube ensures that the material flows accurately into the mold box, avoiding material waste and leakage. The connection and disassembly of each component are relatively easy, which facilitates daily maintenance and cleaning of the equipment.
[0007] Furthermore, two support columns arranged in a mirror image are fixedly connected to the upper end of the base plate, and a top plate is fixedly connected to the upper end of the two support columns. A hydraulic rod is fixedly connected inside the top plate, and a pressing block is fixedly connected to the telescopic end of the hydraulic rod.
[0008] Through the above solution, the introduction of hydraulic rods realizes mechanized operation. By controlling the extension and retraction of hydraulic rods, the lifting and lowering of the lower pressure block can be easily completed. Automated operation not only improves work efficiency, but also reduces the difficulty and error of manual operation. When the hydraulic rods extend and retract, the lower pressure block can evenly apply pressure to the movable sealing plate of the feeding device, and evenly extrude the denture material in the denture material container.
[0009] Furthermore, a rotating plate is fixedly connected to the end of the mounting column away from the support rod.
[0010] Using the above method, the mounting post can be easily screwed into the threaded hole by simply rotating the rotating plate.
[0011] Furthermore, a feed inlet is provided through one side of the mold box.
[0012] The above solution allows the mold material to be directly injected into the mold box without going through complex pipes or systems. This direct feeding method simplifies the operation process and reduces material waste.
[0013] Furthermore, the two molded boxes are fixedly connected by bolts.
[0014] Through the above scheme, bolt connection is a reliable connection method that can provide sufficient strength and rigidity to ensure that the two mold boxes remain tightly connected during the molding process without relative movement or deformation. Bolt connection is also detachable, making it convenient for users to disassemble and reassemble the mold boxes when needed.
[0015] Furthermore, the mounting post is threaded into the threaded hole.
[0016] The above solution demonstrates that threaded connection is a very stable connection method, ensuring a firm and reliable connection between the mounting post and the mold box, making it less prone to displacement during the filling of mold material.
[0017] Furthermore, both mounting strips are slidably disposed inside the mounting base.
[0018] The above solution provides stable support and positioning for the mold box by sliding the mounting strip inside the mounting base, preventing the mold box from shifting during the pressing process.
[0019] Furthermore, the outer diameter of the threaded tube is the same as the inner diameter of the threaded hole.
[0020] With the above solution, the outer diameter of the threaded tube matches the inner diameter of the threaded hole, ensuring a tight fit between the two. No additional adjustment or calibration is required during installation. Users only need to screw the threaded tube into the threaded hole to achieve a quick and easy connection. During the molding process of dental paraffin models, it can prevent paraffin material from overflowing or leaking, thereby keeping the work area clean and safe.
[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0022] This is a molding box for dental paraffin model casting. The molding device consists of two molding boxes connected to a mounting base on the base plate via mounting strips. This design enhances the stability of the overall structure and helps maintain the fixation and positional accuracy of the molding boxes during the casting process. The mounting post connects to the molding boxes via threaded holes, fixing the paraffin model between the two molding boxes and ensuring the stability and precision of the paraffin model during casting. The dental prosthesis material container in the feeding device is equipped with a movable sealing plate and a threaded tube. The movable sealing plate controls the injection volume of dental prosthesis material, while the threaded tube ensures that the dental prosthesis material flows accurately into the molding box, avoiding material waste and leakage. The connection and disassembly of each component are relatively easy, which facilitates the daily maintenance and cleaning of the equipment. Attached Figure Description

[0030] Please see Figure 1 , Figure 2 and Figure 3 This embodiment provides a mold box for casting dental paraffin models, comprising a molding device 1, a feeding device 2, a mounting post 104, and a base plate 3. The molding device 1 includes two mold boxes 101, each with a mounting strip 102 fixedly connected to one side. Threaded holes 103 are provided at the upper ends of the two mold boxes 101. A support rod 105 is fixedly connected to one side of the mounting post 104. Four fixing pins 106 arranged in a circular array are fixedly connected to the end of the support rod 105 away from the mounting post 104. The mounting post 104 is connected to the mold box 101 through the threaded holes 103, which can fix the paraffin model between the two mold boxes 101, ensuring the stability and accuracy of the paraffin model during the casting process. The feeding device 2 includes a dental prosthesis material container 201. The dental material container 201 has a movable sealing plate 202 slidably connected inside, and a threaded tube 203 is fixedly connected to the bottom of the dental material container 201. The dental material container 201 in the feeding device 2 is equipped with a movable sealing plate 202 and a threaded tube 203. The movable sealing plate 202 can control the injection amount of dental material, while the threaded tube 203 ensures that the dental material can flow accurately into the mold box 101, avoiding material waste and leakage. Two mounting seats 4 arranged in a mirror distribution are fixedly connected to the upper end of the base plate 3. The molding device 1 consists of two mold boxes 101 and is connected to the mounting seats 4 on the base plate 3 through the mounting strip 102. This design enhances the stability of the overall structure and helps to maintain the fixation and position accuracy of the mold box 101 during the molding process.
[0031] Please see Figure 1 and Figure 4Two support columns 5 arranged in a mirror image are fixedly connected to the upper end of the base plate 3. A top plate 6 is fixedly connected to the upper end of the two support columns 5. A hydraulic rod 7 is fixedly connected inside the top plate 6. A lower pressure block 8 is fixedly connected to the telescopic end of the hydraulic rod 7. The introduction of the hydraulic rod 7 realizes mechanized operation. By controlling the extension and retraction of the hydraulic rod 7, the lifting and lowering action of the lower pressure block 8 can be easily completed. The automated operation not only improves work efficiency, but also reduces the difficulty and error of manual operation. When the hydraulic rod 7 extends and retracts, the lower pressure block 8 can evenly apply pressure to the movable sealing plate 202 of the feeding device 2, and evenly extrude the denture material in the denture material container 201.
[0032] Please see Figure 2 , Figure 3 and Figure 4 A rotating plate 107 is fixedly connected to the end of the mounting post 104 away from the support rod 105. By simply rotating the rotating plate 107, the mounting post 104 can be easily screwed into the threaded hole 103. A feed port 108 is provided through one side of the mold box 101. The feed port 108 allows the mold material to be directly injected into the mold box 101 without going through complex pipes or systems. This direct feeding method simplifies the operation process and reduces material waste. The two mold boxes 101 are fixedly connected by bolts. Bolt connection is a reliable connection method that can provide sufficient strength and rigidity to ensure that the two mold boxes 101 remain tightly connected during the molding process without relative movement or deformation. The bolt connection is detachable, which is convenient for users to disassemble and reassemble when needed. The mold box 101 and the mounting post 104 are threadedly connected inside the threaded hole 103. The threaded connection is a very stable connection method, ensuring that the connection between the mounting post 104 and the mold box 101 is firm and reliable, making it less likely to shift when filling the model material. Both mounting strips 102 are slidably set inside the mounting base 4. The outer diameter of the threaded tube 203 is the same as the inner diameter of the threaded hole 103. The matching of the outer diameter of the threaded tube 203 and the inner diameter of the threaded hole 103 ensures a tight fit between the two. No additional adjustment or calibration is required during installation. The user only needs to screw the threaded tube 203 into the threaded hole 103 to achieve a quick and easy connection. During the molding process of dental paraffin models, it can prevent paraffin material from overflowing or leaking, thereby keeping the work area clean and safe.
[0033] In this embodiment, the molding device 1 for casting dental paraffin models consists of two mold boxes 101, which are connected to the mounting base 4 on the base plate 3 via mounting strips 102. This design enhances the stability of the overall structure and helps to maintain the fixation and positional accuracy of the mold boxes 101 during the casting process. The mounting post 104 is connected to the mold box 101 through threaded holes 103, which can fix the paraffin model between the two mold boxes 101, ensuring the stability and accuracy of the paraffin model during the casting process. The dental prosthesis material container 201 in the feeding device 2 is equipped with a movable sealing plate 202 and a threaded tube 203. The movable sealing plate 202 can control the injection amount of dental prosthesis material, while the threaded tube 203 ensures that the dental prosthesis material can flow accurately into the mold box 101, avoiding material waste and leakage. The connection and disassembly between the various components are relatively easy, which is beneficial to the daily maintenance and cleaning of the equipment.
[0034] It should be noted that the device consists of three independent parts that can be combined during use. The threaded tube 203 can be installed inside the threaded hole 103 via threads.
[0035] The working principle of the above embodiments is as follows:
[0036] First, fix the paraffin model to one end of the support rod 105 using the fixing pin 106 to ensure model stability. Rotate the rotating plate 107 to thread the mounting post 104 into the threaded hole 103 at the upper end of the mold box 101. Fix the paraffin model between the two mold boxes 101 using the support rod 105 and the fixing pin 106. Use bolts to tightly connect the two mold boxes 101 together to ensure that there will be no relative movement or deformation during the molding process. Add an appropriate amount of model material between the two mold boxes 101 through the feed port 108 to form a mold cavity. Wait for the model material to solidify in the mold cavity until the mold cavity is stable. Rotate the mounting post 104 in the opposite direction to remove the support rod 105 and the fixing pin 106 from the mold box 101. Place the entire mold box 101 into boiling water to melt the paraffin and allow it to flow out. After the mold material dries, the two mold boxes 101 are installed between the two mounting seats 4 on the base plate 3 via the mounting strip 102. The threaded tube 203 of the feeding device 2 is aligned and screwed into the threaded hole 103 on the mold box 101, ensuring a tight and leak-free connection. It is also ensured that the movable sealing plate 202 inside the denture material container 201 corresponds to the lower pressure block 8 at the bottom of the hydraulic rod 7. The hydraulic rod 7 is activated, causing the lower pressure block 8 to descend and apply pressure evenly to the movable sealing plate 202 of the denture material container 201, extruding the denture material evenly through the threaded tube 203 into the mold cavity inside the mold box 101. The denture material is then allowed to solidify inside the mold box 101. During this period, the hydraulic rod 7 remains in a downward state to prevent leakage of the denture material. After solidification, the hydraulic rod 7 is turned off, and all components are disassembled to remove the denture model.
