Technical Field

[0001] This utility model relates to the field of orthodontic appliance demolding technology, specifically to a bracketless orthodontic appliance demolding device. Background Technology

[0002] A clear aligner is a transparent orthodontic appliance designed and manufactured using computer-aided design. A clear aligner release device is a device that separates the aligner's membrane from the dental model.

[0003] A Chinese patent with publication number CN205359668U discloses a release hook forceps for a clear aligner, including a handle, jaws, and jaws; the jaws are a pair of inwardly hooked filaments that can be inserted into release holes on a dental model. The release system for the clear aligner includes the aforementioned release hook forceps and release holes located on the surface of the dental model. The release holes are arranged in pairs, with one hole on the lingual side and the other on the buccal side in each pair; the release holes fit with the jaws of the hook forceps; the release holes are located on the gingival line of the dental model.

[0004] During demolding, because the polymer film adheres to the dental mold and the film is relatively thin, it is time-consuming and laborious to peel the film off the dental mold with fingers or pliers, resulting in low demolding efficiency and often causing damage to the orthodontic appliance due to uneven force. Utility Model Content

[0005] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide a bracketless orthodontic appliance demolding device.

[0006] According to the present invention, a bracketless orthodontic appliance demolding device includes a frame, a press, and a positioning base. The press is located at the top of the frame, and the positioning base is located at the bottom of the frame. The force-applying end of the press acts on the orthodontic appliance mold through a pressure-applying component, and the orthodontic appliance mold is located on the positioning base. The pressure application assembly includes a pressure plate, on which a first pressure rod and a second pressure rod are provided. The first pressure rod is used to apply pressure to the action point of the dental mold of the orthodontic appliance solid model, and the second pressure rod is used to apply pressure to the action point of the diaphragm of the orthodontic appliance solid model. The working stroke of the first pressure rod is greater than that of the second pressure rod.

[0007] Preferably, one end of the second pressure rod used to apply pressure to the diaphragm includes a pressure block, and a buffer spring is sleeved on the second pressure rod, one end of the buffer spring abutting against the pressure plate, and the other end of the buffer spring abutting against the pressure block.

[0014] Preferably, the shape of the recess matches the shape of the diaphragm.

[0015] Preferably, the shape of the channel matches the shape of the dental mold.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model separates the dental mold and the diaphragm by setting a first pressure rod and a second pressure rod to act on the dental mold and the diaphragm respectively. The stroke of the first pressure rod is greater than that of the second pressure rod, which realizes the separation of the dental mold and the diaphragm.

Detailed Implementation

[0019] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0020] like Figure 1-4 As shown, a bracketless orthodontic appliance demolding device according to this utility model includes a frame 1, a press 3, and a positioning base 12. The press 3 is located at the top of the frame 1, and the positioning base 12 is located at the bottom of the frame 1. The force-applying end of the press 3 acts on the orthodontic appliance physical mold through a pressure-applying component, and the orthodontic appliance physical mold is placed on the positioning base 12. The pressure-applying component includes a pressure plate 7, on which a first pressure rod 11 and a second pressure rod 8 are provided. The first pressure rod 11 is used to apply pressure to the dental mold of the orthodontic appliance physical mold at the point of action, and the second pressure rod 8 is used to apply pressure to the diaphragm of the orthodontic appliance physical mold at the point of action. The stroke of the first pressure rod 11 is greater than the stroke of the second pressure rod 8.

[0021] The demolding device of this invention uses a first pressure rod 11 and a second pressure rod 8 to act on the dental mold and diaphragm of the orthodontic appliance, respectively. Because the stroke of the first pressure rod 11 is greater than that of the second pressure rod 8, the dental mold moves downward a greater distance under the action of the first pressure rod 11, thereby separating the dental mold from the diaphragm. This demolding device uses mechanical tools to separate the dental mold from the diaphragm, achieving demolding of the orthodontic appliance. Compared to manually separating the diaphragm from the dental mold by hand or using pliers, the separation efficiency is high, improving the overall mold-making efficiency.

[0022] The orthodontic appliance physical model includes a diaphragm, a dental mold, and a bracketless orthodontic appliance. The bracketless orthodontic appliance is placed in a groove within the dental mold, and the diaphragm, made of polymer, covers the outside of the dental mold. The polymer diaphragm is adhered to the dental mold using vacuum molding. During demolding, the dental mold is first cut along its circumference to reduce the adhesion between the polymer diaphragm and the dental mold. Then, the bracketless orthodontic appliance demolding device of this invention separates the dental mold from the diaphragm. The action points of the dental mold are distributed at its two ends and the middle position. The bracketless orthodontic appliance is placed in the groove. When the first pressure rod 11 acts on the action points of the dental mold, it will not press on the bracketless orthodontic appliance in the groove, thus preventing damage to the bracketless orthodontic appliance. The diaphragm has three action points, evenly distributed around its perimeter. The three action points, when connected sequentially, form an isosceles triangle.

[0023] The press 3 serves as the power source for the demolding device. The press 3 can be a manual press, providing vertical downward pressure to the pressing components. The force-applying end of the press 3 is preferably a force-applying lever 5, with one end mounted on the press 3 and the other end connected to the pressure plate 7. The force-applying lever 5 is preferably made of cast iron to ensure its strength and stability. The manual press also includes an operating lever 4 for controlling the movement of the force-applying lever 5. The operating lever 4 utilizes the lever principle, using a long lever arm to reduce effort and lower manual labor intensity. The principle of the manual press is consistent with the principle of drill bit height adjustment in existing vertical drilling machines.

[0024] Specifically, a fixed base 14 is provided between the positioning base 12 and the frame 1. The positioning base 12 is mounted on the frame 1 via the fixed base 14 and can be fixed to the fixed base 14 with screws. The fixed base 14 serves as a support. The positioning base 12 includes a recess 16 and a channel 13 for the dental model to pass through. The orthodontic appliance solid model is placed in the recess 16, which supports the aligner diaphragm. The shape of the recess 16 can be similar to the aligner diaphragm, but its size is relatively larger to facilitate the placement of the aligner diaphragm. The channel 13 is located below the recess 16 and connects to it. The channel 13 is similar in shape to the dental model, but its size is larger to facilitate the smooth descent of the dental model after separation. The fixed base 14 is provided with a sloping groove 15, which is connected to the channel 13. It is used for the automatic sliding out of the separated dental mold, so that the dental mold can fall smoothly into the sloping groove 15 after separation through the channel 13 for easy collection.

[0025] Specifically, the frame 1 may include a support rod 2 and a support plate. One end of the support rod 2 is mounted on the support plate, and the other end of the support rod 2 is equipped with a press 3. The press 3 includes a pressure rod 5. The bottom of the pressure rod 5 is equipped with a fixed shaft 6, and the bottom of the fixed shaft 6 is equipped with a pressure plate 7. Below the pressure plate 7 is a pressure assembly, which includes a first pressure rod 11 and a second pressure rod 8. Below the pressure assembly are a diaphragm and a dental mold for placing the solid model of the orthodontic appliance to be separated. The first pressure rod 11 acts on the dental mold, and the second pressure rod 8 acts on the diaphragm. The stroke of the first pressure rod 11 pressing down on the dental mold is greater than the stroke of the second pressure rod pressing down on the diaphragm. The dental mold moves down more stroke relative to the diaphragm, and the diaphragm separates from the dental mold.

[0026] Specifically, the first pressure rod 11 can be fixedly connected to the pressure plate 7 and moves synchronously with the pressure plate 7. There are three first pressure rods 11, which are distributed in an isosceles triangle on the pressure plate 7. The three first pressure rods 11 are located above the channel 13. The three first pressure rods 11 assist in applying a uniform demolding force to the dental mold to ensure that the dental mold separates smoothly from the diaphragm. One end of the second pressure rod 8 used to apply pressure to the diaphragm includes a pressure block 9. A buffer spring 10 is sleeved on the second pressure rod 8. One end of the buffer spring 10 abuts against the pressure plate 7, and the other end of the buffer spring abuts against the pressure block. One feasible implementation is as follows: the second pressure rod 8 is a support pin, which passes through the pressure plate 7. A buffer spring 10 is sleeved on the support pin, and a pressure block 9 is provided at the bottom of the support pin. The upper end of the buffer spring 10 contacts the lower side plate of the pressure plate 7, and the lower end of the buffer spring 10 contacts the upper side wall of the pressure block 9. The pressure plate 7 has a support pin hole that mates with the support pin. The upper end of the support pin is larger than the support pin hole, thus restricting the downward movement of the support pin. The buffer spring 10 is a stainless steel compression spring, which is sleeved on the support pin and located below the pressure plate 7. The lower end of the buffer spring 10 is positioned by the pressure block 9, providing elastic cushioning during use. There are three second pressure rods 8, which are distributed in an isosceles triangle on the pressure plate. The three second pressure rods are located above the recess 16 but not above the channel 13. The three second pressure rods 8 assist in applying a uniform demolding force to the diaphragm to ensure smooth separation of the diaphragm from the dental mold.

[0027] When demolding, the manual press is used to apply force. The pressure bar 5 moves downward, causing the pressure plate 7 to move downward. The pressure plate 7 causes the first pressure bar 11 and the second pressure bar 8 to move downward. The pressure block 9 of the second pressure bar 8 acts on the diaphragm in the recessed part 16, generating a downward pressure on the diaphragm. The buffer spring 10 provides cushioning and restricts the diaphragm of the bracketless orthodontic appliance. At the same time, the end of the first pressure bar 11, preferably the cylindrical end, acts on the dental model at the point of action. The first pressure bar 11 generates a downward pressure on the dental model. The downward stroke of the first pressure bar 11 is greater than the downward stroke of the second pressure bar, and the dental model separates from the diaphragm. The separated dental model falls down from the channel into the inclined groove and slides out, completing the separation of the dental model from the diaphragm. Then, the orthodontic appliance is manually removed from the groove of the dental model to obtain the required bracketless orthodontic appliance.

[0028] This invention features a positioning base 12 for placing the diaphragm of the bracketless orthodontic appliance to be separated from the dental mold. When the first pressure rod 11 and the second pressure rod 8 below the pressure plate 7 press down, the diaphragm of the bracketless orthodontic appliance and the dental mold can be separated. The separated dental mold falls down from the channel and slides out of the inclined groove, completing the separation. Compared with manual separation, this demolding device has a higher separation efficiency. The three first pressure rods 11 are evenly stressed, which can better separate the two. The demolding device of this invention is easy to control and has high positioning accuracy.
