Description

Technical Field

[0001] This utility model relates to the field of dental prosthesis technology, specifically a custom-made dental wax pattern forming device. Background Technology

[0002] Dentures, also known as "false teeth" in everyday life, are a general term in the medical field for restorations used to replace missing teeth. They are suitable for cases where some or all of the teeth in the upper or lower jaw are missing. Just as "prosthetic limbs" refer to artificially manufactured "artificial hands" or "artificial legs" as replacements for limbs, "dentures" also fulfill the function of "fulfilling obligations" for the human body—that is, restoring the chewing, pronunciation, and aesthetic functions that teeth should have. They reconstruct oral function and appearance artificially, helping patients return to a normal life, hence the name "dentures".

[0003] An investigation revealed that a Chinese utility model patent discloses a customized removable denture wax pattern forming device (publication number: CN213552525U), which includes a first mounting plate. Supports are symmetrically fixedly connected to both sides of the bottom wall of the first mounting plate. A first mounting groove is formed between the center positions of the upper and lower side walls of the first mounting plate. A copper plate is fixedly connected to the first mounting groove. A lower mold is fixedly connected to the center position of the top wall of the copper plate. An upper mold is closed on the top wall of the lower mold. Connecting seats are symmetrically fixedly connected to both sides of the top wall of the first mounting plate.

[0004] While the aforementioned patent, through its structural design, includes a heating mechanism within the molding mechanism, facilitating the closing and shaping of the upper and lower molds and resulting in high actual mold-closing efficiency and good material fit within the mold cavity, and also features an auxiliary cooling and molding mechanism for the upper and lower molds, allowing for faster cooling and shaping during the actual custom removable denture wax pattern molding process, the use of two independent cylinders to drive the upper mold for mold-closing operations increases energy consumption and maintenance costs. The difficulty in synchronous control of the two cylinders also leads to uneven force application, causing the upper and lower molds to shift or tilt during the closing process, severely affecting mold-closing accuracy. Furthermore, the lack of a precise and stable guiding structure makes it impossible to effectively guarantee the vertical alignment between the upper and lower molds during mold-closing. Incorrect guidance directly leads to mold edge misalignment and cavity deformation, resulting in wax pattern dimensional deviations and poor edge fit, severely impacting the clinical fitting accuracy of the denture. Additionally, the impact vibration and mechanical noise and structural fatigue during mold-closing can affect the equipment's lifespan.

[0005] Therefore, this utility model provides a customized denture wax pattern forming device to solve the above problems. Utility Model Content

[0006] (a) Technical problems to be solved This invention provides a customized dental wax pattern forming device, which aims to solve the problems mentioned in the background art.

[0007] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a customized denture wax pattern forming device, comprising a worktable, the inner cavity of which is provided with two fixed plates, a mold is provided on one side of the fixed plates, two fixed cylinders are fixedly connected to the bottom of the inner cavity of the worktable, a damper is fixedly connected to the bottom of the inner cavity of the fixed cylinder, a rubber pad is fixedly connected to the top of the damper, a sliding plate is slidably connected to the inner cavity of the fixed cylinder, a rack is fixedly connected to one side of the sliding plate, a connecting block is fixedly connected to the top of the sliding plate, and two rotating rods are provided in the inner cavity of the worktable, with a gear fixedly connected to one end of each rotating rod.

[0008] As a preferred technical solution of this application, a cylinder is fixedly installed on the top of the inner cavity of the workbench, the output end of the cylinder is fixedly connected to one side of an adjacent fixed plate, and the bottom of the inner cavity of the workbench is fixedly connected to one side of an adjacent fixed plate.

[0009] As a preferred technical solution of this application, one end of the rotating rod is rotatably connected to the inner wall of the adjacent workbench through a rotating shaft, one side of the connecting block is fixedly connected to one side of the adjacent mold, and the gear and the rack mesh with each other through a snap-fit ​​mechanism.

[0010] As a preferred technical solution of this application, a plurality of limiting blocks are fixedly connected to one side of the mold, a first threaded groove is provided on one side of the limiting block, and a magnetic plate is fixedly connected to one side of the limiting block.

[0011] As a preferred technical solution of this application, a plurality of limiting grooves adapted to the limiting blocks are provided on one side of the fixing plate, and a magnetic block is fixedly connected to the bottom of the inner cavity of the limiting groove. One side of the magnetic block is attracted to one side of the adjacent magnetic plate by magnetism.

[0012] As a preferred technical solution of this application, a first threaded groove is provided on one side of the limiting block, and multiple second threaded grooves are provided on both sides of the fixing plate.

[0013] As a preferred technical solution of this application, a heating plate is fixedly installed on one inner wall of the workbench, and protective doors are hinged to both inner walls of the workbench.

[0014] (III) Beneficial Effects By adopting a single-cylinder configuration, energy consumption and maintenance costs of the equipment are reduced, while the reliability and consistency of operation are improved. During mold closing, the connecting block drives the sliding plate to slide within the fixed cylinder, and the meshing transmission of the rack and gear forms a guide. This allows for real-time adjustment of the force balance on both sides during mold closing, preventing tilting or misalignment caused by differences in resistance on one side. This improves the alignment accuracy and mold closing stability between molds, effectively avoiding defects such as mold edge misalignment and cavity deformation caused by misalignment of the guide. It ensures the accuracy of the wax pattern dimensions and the tightness of the edges, improving the molding quality and clinical fit of the denture wax pattern. With the addition of rubber pads and dampers, it can absorb impact vibrations at the moment of mold closing, reducing mechanical noise and structural fatigue, and extending the service life of the equipment.

[0015] By using limit blocks, limit grooves, magnetic blocks, magnetic plates, first threaded grooves, second threaded grooves, and bolts, the mold can be quickly installed and replaced, avoiding errors caused by repeated manual adjustments. Multiple fixings ensure the tightness of the installation and ensure that the mold remains firmly connected throughout the molding cycle and will not loosen due to mold closing pressure.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] This utility model provides a customized dental wax pattern forming device, such as Figure 1 - Figure 5 As shown, the technical solution includes a workbench 1. The inner cavity of the workbench 1 is provided with two fixed plates 4. A mold 5 is provided on one side of the fixed plate 4. Two fixed cylinders 7 are fixedly connected to the bottom of the inner cavity of the workbench 1. A damper 13 is fixedly connected to the bottom of the inner cavity of the fixed cylinder 7. A rubber pad 14 is fixedly connected to the top of the damper 13. A sliding plate 10 is slidably connected to the inner cavity of the fixed cylinder 7. A rack 11 is fixedly connected to one side of the sliding plate 10. A connecting block 12 is fixedly connected to the top of the sliding plate 10. The inner cavity of the workbench 1 is provided with two rotating rods 6. A gear 9 is fixedly connected to one end of the rotating rod 6.

[0020] A cylinder 20 is fixedly installed on the top of the inner cavity of the workbench 1. The output end of the cylinder 20 is fixedly connected to one side of the adjacent fixed plate 4. The bottom of the inner cavity of the workbench 1 is fixedly connected to one side of the adjacent fixed plate 4. The piston rod of the cylinder 20 extends and retracts, causing the fixed plate 4 to reciprocate in the vertical direction, thereby driving the upper mold 5 connected to it to realize the action of rising to open the mold and falling to close the mold.

[0021] One end of the rotating rod 6 is rotatably connected to the inner wall of the adjacent workbench 1 via a rotating shaft. One side of the connecting block 12 is fixedly connected to one side of the adjacent mold 5. The gear 9 and the rack 11 mesh with each other through a snap-fit ​​mechanism. When the upper mold 5 moves up and down with the fixed plate 4, it drives the connecting block 12 and the sliding plate 10 to move synchronously. This causes the rack 11 to drive the gear 9 to rotate during the sliding process. The rotation of the gear 9 applies a constraint force to the rack 11, which enhances the synchronicity of movement on both sides and the guiding stability during the mold closing process. This effectively prevents the mold 5 from tilting or misaligning due to uneven force, and improves the mold closing accuracy.

[0022] Several limiting blocks 15 are fixedly connected to one side of the mold 5. A first threaded groove 17 is opened on one side of the limiting block 15. A magnetic plate 19 is fixedly connected to one side of the limiting block 15. When the limiting block 15 on the mold 5 is aligned with the limiting groove 16 on the fixing plate 4 and inserted, the magnetic plate 19 and the magnetic suction block 18 generate magnetic attraction, realizing the initial positioning and fixing of the mold 5. The operation is convenient and provides operational convenience and safety for the subsequent tightening of the bolt 8.

[0023] A number of limiting grooves 16 adapted to the limiting block 15 are provided on one side of the fixed plate 4. A magnetic block 18 is fixedly connected to the bottom of the inner cavity of the limiting groove 16. One side of the magnetic block 18 is attracted to one side of the adjacent magnetic plate 19 by magnetism. The magnetic block 18 and the magnetic plate 19 automatically magnetically attract each other, realizing the positioning and anti-loosening function of the mold 5 before fastening.

[0024] The limiting block 15 has a first threaded groove 17 on one side, and the fixing plate 4 has multiple second threaded grooves 21 on both sides. The outer ring of the fixing plate 4 is provided with several bolts 8. One end of the bolt 8 passes through the inner cavity of the adjacent second threaded groove 21 and connects with the inner cavity of the corresponding first threaded groove 17 by threaded engagement. The bolts 8 pass through the second threaded grooves 21 on the fixing plate 4 in sequence and are screwed into the first threaded groove 17 inside the upper limiting block 15 of the mold 5, realizing a firm connection between the mold 5 and the fixing plate 4, ensuring that the mold 5 does not shift during the mold closing process, improving the overall stability and safety, and ensuring the reliability of the molding process.

[0025] A heating plate 3 is fixedly installed on one inner wall of the workbench 1. Both inner walls of the workbench 1 are hinged with protective doors 2. After the heating plate 3 is powered on, it heats the internal space of the workbench 1 evenly, which is conducive to the flow and adhesion of wax in the mold cavity and improves the molding quality. When the protective door 2 is closed, it can reduce heat loss and improve thermal efficiency.

[0026] Specifically: During the custom-made denture wax pattern molding process, cylinder 20 is first activated. The piston rod of cylinder 20 retracts upward, causing the fixed plate 4, which is fixedly connected to it, to rise vertically. The upward movement of the fixed plate 4 is transmitted to the upper mold 5, causing the upper mold 5 to move upward synchronously, thereby separating the upper mold 5 from the lower mold 5 and creating sufficient operating space. After the two molds 5 are completely separated, the operator can accurately place the pre-prepared denture wax pattern molding material into the cavity of the lower mold 5. Subsequently, the cylinder 20 is controlled to reverse its movement. The piston rod extends downward, pushing the fixed plate 4 to descend smoothly in the vertical direction. The fixed plate 4 drives the upper mold 5 to move downward synchronously, gradually approaching and finally closing with the lower mold 5, completing the mold closing action. During the process of the cylinder 20 driving the fixed plate 4 to press down for mold closing, the connecting blocks 12 connected to both sides of the upper mold 5 move downward synchronously. The connecting blocks 12 are fixedly connected to the ends of the sliding plate 10, thereby driving the sliding plate 10 to slide in a straight line inside the fixed cylinder 7. The sliding of the sliding plate 10 causes the rack 11 connected to it to produce horizontal displacement. The rack 11 and the gear 9 are connected... The rack 11 meshes with the gear 9, causing the gear 9 to rotate. The rotation of the gear 9, in turn, exerts a counterforce on the rack 11, creating a balanced guiding mechanism that effectively limits the swaying tendency during sliding and improves the guiding stability of the entire mold-closing process. When the sliding plate 10 continues to move downwards with the connecting block 12 to the end of its stroke, its end contacts and compresses the rubber pad 14. The rubber pad 14 undergoes elastic deformation, absorbing some of the vibration energy and transmitting the residual vibration force to the damper 13 connected to it. The damper 13 further dissipates the vibration through its internal damping medium. Energy is used to effectively buffer the impact of mold closing. When installing or replacing mold 5, the operator installs mold 5 on fixed plate 4, aligns the limiting block 15 connected to mold 5 with and embeds it into the limiting groove 16 opened on fixed plate 4 to achieve initial positioning of mold 5. Subsequently, magnetic plate 19 and magnetic block 18 have a magnetic attraction effect, keeping mold 5 stable and not loose. Finally, bolts 8 are used to pass through the second threaded groove 21 on fixed plate 4 and the first threaded groove 17 inside the upper limit block 15 of mold 5 in sequence, and tighten them to complete the firm installation and precise positioning of mold 5.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
