Description

Technical Field

[0001] The present application relates to the technical field of denture processing, and more specifically, to a crown sintering positioning plate. Background Art

[0002] During the denture processing, the industry usually uses zirconia sintering furnaces to sinter crowns. Currently, dental hospitals, large dental clinics, and denture processing companies use zirconia sintering furnaces to sinter crowns, which is a common process for denture processing.

[0003] In the current denture sintering process, multiple crowns to be sintered are typically placed in a sintering bowl, which is then placed in a sintering furnace for sintering. The sintering bowl has only one receiving space, and placing multiple crowns in one space can easily cause them to move and collide in the sintering furnace, potentially leading to hidden cracks in the finished product. Furthermore, the crowns are randomly placed in a single space, making it difficult to distinguish between the mixed crowns.

[0004] Therefore, the existing technology still needs to be improved and developed. Utility Model Content

[0005] The purpose of the present application is to provide a dental crown sintering positioning plate, which solves the problem in the prior art that multiple dental crowns are easily collided and placed in a disorderly manner during the sintering process in the sintering bowl.

[0006] To achieve the above objectives, the technical solution adopted in this application is:

[0007] The present application provides a crown sintering positioning plate, comprising: a plate body, a sintering cavity with an open opening provided in the plate body,

[0011] A plurality of longitudinal partitions and a plurality of transverse partitions are interlaced to form sintering compartments.

[0012] Optionally, the plurality of longitudinal partitions and the plurality of transverse partitions are vertically staggered and form a plurality of square sintering compartments in the middle of the sintering cavity.

[0013] Optionally, both the transverse partition and the longitudinal partition are lower than the surface of the open opening of the tray, so that the multiple sintering compartments are connected at the side facing the open opening.

[0017] When multiple trays are stacked, the outer chamfer of the upper tray is embedded in the inner chamfer of the lower tray.

[0018] Optionally, a positioning groove is provided on the outer edge of the bottom of the tray body, and an inner positioning platform is provided on the edge of the open mouth of the tray body;

[0022] The present application provides a dental crown sintering positioning tray with at least one beneficial effect: by providing a baffle within the tray, the baffle divides the sintering chamber into multiple sintering compartments, each of which is used to place a dental crown to be sintered. Therefore, different dental crowns to be sintered are placed in sintering compartments of different tubes, thereby creating a grid-like partition within the sintering tray.

[0032] The existing crown sintering bowl not only lacks a grid to stabilize the zirconia denture, but is also easy to move and collide in the sintering furnace, which may lead to the problem of hidden cracks in the sintered finished product. Moreover, the height of the existing sintering bowl is relatively high, and a sintering furnace can sinter at most two plates at the same time, resulting in a low sintering capacity. Since the denture crowns are mixed in the sintering bowl, confusion occurs, and the fired crowns must be manually distinguished during the subsequent processing. However, manual identification can only be performed based on the appearance of the crowns, which makes it difficult for inexperienced operators to distinguish the crowns. In addition, since the crowns are mixed and difficult to distinguish in the sintering bowl, it is impossible to query the denture positioning information, resulting in a time-consuming and labor-intensive search process, and it is also impossible to connect to the digital process to digitally monitor the crown processing process, resulting in an inability to connect to the subsequent ERP system for serial digitalization and fully automated processes. In order to solve the above problems, the present application proposes the following embodiments.

[0033] like Figure 1 、 Figure 2 As shown, this embodiment proposes a crown sintering positioning disk, which mainly includes: a disk body 100 and a baffle 200. The disk body 100 can adopt various shapes, such as round, square, polygonal, etc. The disk body 100 of this embodiment is usually a circular disk, and a sintering cavity with an open mouth 110 is provided in the disk body 100, and the open mouth 110 faces upward. Therefore, the disk body 100 has a side wall and a bottom, the thickness of the side wall can be 6.5 mm, and the thickness of the bottom can be 7 mm; the use of a disk body 100 of this thickness can effectively prevent the sintering bowl from cracking due to high temperature during the sintering process. The baffle 200 is arranged in the disk body 100, and divides the sintering cavity into a plurality of sintering compartments 230, and each sintering compartment 230 is used to place the crown to be sintered. Since each sintering compartment 230 is separated, each crown to be sintered can be separated individually.

[0034] like Figure 1 、 Figure 2 As shown, the crown sintering positioning tray of this embodiment employs a baffle 200 disposed within the tray body 100, which divides the sintering chamber into multiple sintering compartments 230. Each sintering compartment 230 is used to hold a crown to be sintered. Different crowns to be sintered are placed in separate sintering compartments 230, creating a grid-like separation within the sintering tray. This not only separates the crowns to prevent displacement and collision during the sintering process, but also significantly reduces the possibility of hidden cracks in the finished sintered product due to collisions, thereby improving overall quality. Furthermore, by storing different crowns in the sintering compartments 230, mixed crowns can be separated, making them easier to identify and locate, and making it more convenient for the operator to find the crowns.

[0035] like Figure 1 、 Figure 2As shown, the barrier portion 200 of this embodiment specifically includes: multiple transverse baffles 210 and multiple longitudinal baffles 220. The multiple transverse baffles 210 are arranged side by side and spaced apart, and the multiple longitudinal baffles 220 are arranged side by side and spaced apart. Both ends of the transverse baffles 210 and the longitudinal baffles 220 are connected to the inner wall of the sintering chamber, thereby stably and fixedly connected to the transverse baffles 210 and the longitudinal baffles 220 within the tray body 100. The multiple longitudinal baffles 220 and the multiple transverse baffles 210 are staggered to form a sintering compartment 230. The transverse baffles 210 and the longitudinal baffles 220 in this embodiment have the same thickness, and can be made of 2mm thick plates, which can withstand the high temperature during the sintering process. By staggering to form a grid-like sintering compartment 230, collision or adhesion between crowns due to uncertain factors during the sintering process is avoided, ensuring the sintering effect.

[0036] like Figure 1 、 Figure 2 As shown, further, in this embodiment, the multiple longitudinal partitions 220 and the multiple transverse partitions 210 are vertically staggered to form multiple square sintering compartments 230 in the center of the sintering chamber. In the length and width directions, the transverse partitions 210 and the longitudinal partitions 220 are respectively connected to the inner wall of the sintering chamber to form a sintering compartment 230 with an arc-shaped side. This sintering compartment 230 can be larger than the square sintering compartment 230. The square sintering compartment 230 in the center has a grid size of 20×20×8.5mm (length×width×height), which can meet 99% of dental sintering needs and is also convenient for loading and unloading. The sintering compartments 230 on both sides of the length and width directions can accommodate relatively large dental crowns, thereby improving practicality. Therefore, the present tray body 100 can form 12 sintering compartments 230, allowing 12 dental crowns to be sintered at a time. Furthermore, the crowns are sintered separately through the sintering compartment 230, which can quickly confirm the sintered teeth and provide a port for subsequent digital production processes such as tooth finding.

[0037] like Figure 1 、 Figure 2 As shown, in this embodiment, the transverse partitions 210 and the longitudinal partitions 220 are both lower than the surface of the opening 110 of the tray body 100, so that the multiple sintering compartments 230 are connected on the side facing the opening 110. Since the upper portions of the sintering compartments 230 are connected, during the sintering process, the high-temperature gas in each sintering compartment 230 can flow, thereby making the temperature of each sintering compartment 230 more uniform.

[0038] like Figure 1 、 Figure 2 As shown, further, an exhaust channel 120 is provided on the outer wall of the tray body 100, and the exhaust channel 120 is connected to the multiple sintering compartments 230. The exhaust channel 120 is connected to the sintering chamber, and hot gas can be released during the sintering process to prevent the occurrence of the phenomenon of chamber explosion.

[0039] like Figure 1 、 Figure 2 As shown, the exhaust channel 120 of this embodiment further includes a plurality of exhaust slots 121 located at the opening 110 of the tray body 100 and distributed along the circumference of the tray body 100. Specifically, a 9×22 mm exhaust slot 121 is provided every 90° around the upper sidewall of the tray body 100. Each exhaust slot 121 is located at the top of the tray body 100, has an opening width of 22 mm, and extends downward by 9 mm. The exhaust slots 121 communicate with the upper portions of each sintering compartment 230, allowing for uniform exhaust from all four sides during the sintering process. This allows for more uniform heat exchange between the various sintering compartments 230 within the tray body 100, preventing excessive heat concentration that could affect sintering quality.

[0040] Furthermore, it should be noted that the height of the sintering bowls currently used on the market is 40 mm. After measurement, the vertical height from the furnace of a conventional sintering furnace to the bottom of the tray when it descends is 84 mm. Therefore, in the prior art, only two sintering bowls can be stacked in the sintering furnace at the same time, and only two sintering bowls can be sintered at a time. The overall height of the tray body 100 of the sintering tray in this embodiment is 26 mm. Therefore, the maximum size of the sintering trays of this embodiment after stacking three is 78 mm, and they can still be placed in the sintering furnace for sintering. Therefore, in this embodiment, by lowering the height of the tray body 100, the number of sintering trays that can be stacked in one sintering process is increased, and more crowns can be sintered at one time, thereby greatly improving production efficiency and accelerating production progress.

[0041] like Figure 3 、 Figure 4 As shown, in this embodiment, the bottom outer edge of the tray body 100 is provided with an outer chamfer 130, and the edge of the opening 110 of the tray body 100 is provided with an inner chamfer 140. When multiple tray bodies 100 are stacked, the outer chamfer 130 of the upper tray body 100 is embedded in the inner chamfer 140 of the lower tray body 100. During the stacking process, the outer chamfer 130 and the inner chamfer 140 cooperate to guide the bottom of the upper tray body 100 and better embed it into the opening 110 of the lower tray body 100, further facilitating the stacking of multiple tray bodies 100. In addition, due to the cooperation of the outer chamfer 130 and the inner chamfer 140, a portion of the bottom of the upper tray body 100 can be embedded in the opening 110 of the lower tray body 100, further reducing the height of the stacked sintering trays and facilitating the placement of multiple stacked sintering trays into the limited space of a sintering furnace.

[0042] like Figure 3 、 Figure 4As shown, in this embodiment, the tray body 100 is further provided with a positioning groove 150 on the outer edge of the bottom, and an inner positioning platform 160 is provided on the edge of the open mouth 110 of the tray body 100. When multiple tray bodies 100 are stacked, the positioning groove 150 of the upper tray body 100 is nested on the inner positioning platform 160 of the lower tray body 100. When the upper sintering tray is stacked on the lower sintering tray, the positioning groove 150 on the bottom of the upper tray body 100 is embedded in the inner positioning platform 160 of the lower tray body 100, so that the upper sintering tray can be accurately positioned on the lower sintering tray without rotating circumferentially, ensuring the stability of the stack of multiple sintering trays.

[0043] Specifically, the positioning groove 150 at the bottom of the tray body 100 is a recessed structure formed on the outer chamfer 130. The inner positioning platform 160 at the opening 110 is a raised platform formed on the inner chamfer 140. The upper surface of the raised platform is flush with the top surface of the side wall of the tray body 100. The positioning grooves 150 and the inner positioning platforms 160 are arranged in a corresponding manner and are symmetrically arranged around the circumference. The height of the inner positioning platforms 160 can be 2.5 mm. The matching structure of the positioning grooves 150 and the inner positioning platforms 160 at four symmetrical positions ensures better stability when the sintering trays are stacked, preventing them from shifting.

[0044] like Figure 2 As shown, further, the sintering compartment 230 of this embodiment is provided with an identification portion 240 corresponding to it, and the identification portion 240 is used to mark each sintering compartment 230. The sintering compartment 230 can prevent the sintering bowl from being placed unsteadily due to human factors, and prevent collisions and adhesions between items, thereby effectively improving the overall production quality; and the provision of corresponding identification portions 240 can enable multiple sintering compartments 230 to play the role of dividing the subsequent information identification and interaction areas. Before sintering, the operator selects the crown, and after selection, places the crown into the corresponding sintering compartment 230. The crown in the sintering compartment 230 is marked by the identification portion 240, so that the corresponding crown can be quickly found through the identification portion 240 in the subsequent process, so that the tooth can be directly positioned in the subsequent processing, which is conducive to the realization of digital processing flow.

[0045] like Figure 2As shown, further, the identification portion 240 of this embodiment includes different identification digits 241, and the different identification digits 241 are respectively arranged on the bottom or side wall of the sintering compartment 230. The sintering bowl is equipped with 12 sintering compartments 230, and each sintering compartment 230 corresponds to an identification digit 241, for example, numbered from 1 to 12. After the selected crown is placed in the sintering compartment 230, the crown is accurately positioned, and in the subsequent digital process connected in series, each crown exchanges information according to the placement position. After automatic typesetting and cutting, it is sintered in its order, and the information is confirmed during sintering. After sintering is completed, the tooth finder selects the tooth by information retrieval and places it in the corresponding order transport box to complete the automated production line.

[0046] In summary, the crown sintering positioning plate provided in the present application adjusts the height of the original sintering bowl. The heights of the three sintering plates of the present application are close to the heights of the original two sintering bowls, and are slightly lower than the vertical distance from the sintering bowl to the bottom of the sintering furnace; the interior of the original sintering bowl is separated by a grid to prevent objects from shifting and colliding, reduce the possibility of collision, and improve the overall quality; the grid form is conducive to determining precise positioning information and connecting subsequent fully digital processes.
