Description

Technical Field

[0001] The present invention relates to the field of embedding tools, and more particularly to a bracket embedding tool. Background Art

[0002] Currently, in the field of orthodontics, brackets, as important components of fixed orthodontic technology, have a crucial impact on the effect of orthodontic treatment and the comfort of patients; the production of brackets requires the use of embedding tools, and the quality of the embedding tools affects whether high-quality metal brackets can be cast.

[0003] Existing embedding tools include a base and an embedding ring. The base is used to fixedly arrange a sprue device with a bracket mold. The embedding ring is sleeved on the base, and the sprue device is located inside the embedding ring; the sprue device includes a main sprue and a sub-sprue, and the sub-sprue is adhered to the main sprue by melting dental wax strips, and the sub-sprue is communicated with the main sprue.

[0004] In view of the above related technologies, when the embedding ring is used for a period of time, the embedding slurry is likely to overflow at the gap between the embedding ring and the base, thus affecting the casting quality and efficiency. Summary of the Invention

[0005] In order to improve the casting quality and efficiency of brackets, the present application provides a bracket embedding tool.

[0006] A bracket embedding tool provided by the present application adopts the following technical solutions:

[0007] A bracket embedding tool includes a base and an embedding ring sleeved on the base. A limiting ring extends circumferentially along the outer circumference of the base. A limiting groove is circumferentially formed at a position of the end of the embedding ring close to the base corresponding to the limiting ring. The limiting ring is inserted into the base through the limiting groove.

[0008] By adopting the above technical solutions, during use, first fix the sprue device on the base, then sleeve the embedding ring on the base, and make the limiting ring insert into the limiting groove, so that the embedding ring and the base are closely matched; when the embedding slurry is subsequently poured into the embedding ring, the overflow of the embedding slurry from the gap between the embedding ring and the base can be reduced, and the casting quality and efficiency of the brackets can be improved.

[0009] Preferably, a clamping groove is circumferentially formed on the outer circumference of the base. The limiting ring is installed at the bottom of the clamping groove. The end of the embedding ring close to the base is clamped to the base through the clamping groove; the inner side wall of the embedding ring abuts against the side wall of the clamping groove.

[0010] By adopting the above technical solution, one end of the embedding ring close to the base is inserted into the clamping groove, and the inner side wall of the embedding ring abuts against the groove side wall of the clamping groove, thereby further improving the fitting tightness between the embedding ring and the base.

[0011] Preferably, the limiting ring is arranged at the middle position of the bottom of the clamping groove.

[0012] By adopting the above technical solution, the clamping between the embedding ring and the base becomes more stable.

[0013] Preferably, the outer side wall of the embedding ring is flush with the outer side wall of the base.

[0014] By adopting the above technical solution, the flatness of the outer side wall of the whole embedding tool is improved, which facilitates the clamping convenience and stability during subsequent processes such as baking.

[0015] Preferably, a forming table is arranged on one side of the base close to the inside of the embedding ring.

[0016] By adopting the above technical solution, the setting of the forming table makes a concave groove formed on the solidified body after the embedding slurry solidifies. During the casting process, the molten metal flows in from the concave groove, and the excess molten metal solidifies at the concave groove. At the same time, these excess molten metals can be used as a supplement for the shrinkage of the cavity metal, avoiding incomplete casting of the workpiece.

[0017] Preferably, one end of the forming table facing the inside of the embedding ring is provided with a socket for inserting the main runner of the gating device.

[0018] By adopting the above technical solution, when installing the gating device, the bottom end of the main runner of the gating device can be directly inserted into the socket to complete the installation, which is convenient for installation.

[0019] Preferably, a through hole is formed in the base, and both ends of the through hole communicate with the socket and the side of the base away from the embedding ring respectively.

[0020] By adopting the above technical solution, when subsequent embedding is carried out, the embedding slurry is poured in. During the solidification process of the embedding slurry, heat is generated, which melts the wax adhered to the main runner and then flows out through the through hole, reducing the wax remaining in the main runner of the gating device.

[0021] Preferably, a sink is arranged on the side of the base away from the embedding ring and corresponding to the through hole, and the diameter of the sink is larger than that of the through hole.

[0022] By adopting the above technical solution, when the wax melts, it can be gathered in the sink, making the molten wax flow out more smoothly, reducing the accumulation and blockage in the through hole, and also making the subsequent cleaning more convenient.

[0023] Preferably, the cross-section of the limiting ring is rectangular.

[0024] By adopting the above technical solution, the embedding ring is inserted into the base more stably.

[0025] Preferably, the cross-section of the limiting ring is trapezoidal.

[0026] By adopting the above technical solution, the limiting ring is inserted into the limiting groove more smoothly, and the inclined surface of the trapezoidal shape can play a guiding role.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. During use, first fix the sprue device on the base, then sleuth the embedding ring on the base, and make the limiting ring insert into the limiting groove so that the embedding ring and the base are closely fitted; when the embedding slurry is poured into the embedding ring subsequently, the overflow of the embedding slurry from the gap between the embedding ring and the base can be reduced, improving the casting quality and efficiency of the bracket;

[0029] 2. The setting of the forming table enables a concave groove to be formed on the solidified body after the embedding slurry solidifies. During the casting process, the molten metal flows in from the concave groove, and the excess molten metal solidifies at the concave groove. At the same time, these excess molten metals can be used as a supplement for the shrinkage of the cavity metal, avoiding incomplete casting of the workpiece;

[0030] 3. When embedding subsequently, pour the embedding slurry. During the solidification process of the embedding slurry, heat is generated, which melts the wax adhered to the main runner and then flows out from the through hole and gathers in the sunken groove, making the molten wax flow out more smoothly, reducing the gathering and blockage in the through hole, and making the subsequent cleaning more convenient.

[0037] The following further elaborates on this application in conjunction with the attached Figures 1-4 drawings for a more detailed description.

[0038] An embodiment of this application discloses a bracket embedding tool.

[0039] Embodiment 1

[0040] Referring to Figure 1 and Figure 2 , the bracket embedding tool includes a base 1 and an embedding ring 2. The base 1 is a circular seat. A clamping groove 11 is circumferentially extended along the outer ring of one side of the base 1. The width of the clamping groove 11 is consistent with the thickness of the embedding ring 2. Along the circumferential direction, a limiting ring 12 is extended at the middle position of the bottom of the clamping groove 11 of the base 1. The cross-section of the limiting ring 12 is rectangular; one end of the embedding ring 2 is clamped to the base 1 through the clamping groove 11. The inner side wall of the embedding ring 2 abuts against the side wall of the clamping groove 11. The outer side wall of the embedding ring 2 is flush with the outer side wall of the base 1; the embedding ring 2 is a hollow cylindrical shape. A limiting groove 21 is circumferentially extended at the end of the embedding ring 2 clamped to the clamping groove 11. The limiting ring 12 is inserted into the base 1 through the limiting groove 21; a receiving space for subsequently introducing embedding slurry is formed between the base 1 and the embedding ring 2; thus, the cooperation between the base 1 and the embedding ring 2 is closer; a guiding inclined surface 13 is circumferentially extended at the notch of the clamping groove 11, making it smoother for the embedding ring 2 to be inserted into the clamping groove 11.

[0041] Referring to Figure 2 and Figure 3 , a forming platform 14 is integrally formed at the middle position of the side of the base 1 facing the receiving space. The forming platform 14 is a semi-circular platform. Thus, a concave groove is formed on the solidified body after the subsequent embedding slurry solidifies, allowing the excess molten metal in the casting process to solidify at the concave groove. At the same time, these excess molten metals can be used as a supplement for the shrinkage of the cavity metal.

[0042] A through hole 15 is opened in the base 1. The through hole 15 extends in the vertical direction. One end of the through hole 15 extends into the forming platform 14 and is connected to the receiving space. The other end of the through hole 15 communicates with the bottom of the base 1; the vertically upward end of the through hole 15 extends into the forming platform 14 and is connected to the receiving space inside; at the position corresponding to the through hole 15 at the end of the forming platform 14 facing the receiving space, a plugging groove 16 is opened. The cross-sectional area of the plugging groove 16 is larger than the cross-sectional area of the through hole 15. The plugging groove 16 is used for inserting the main runner of the gating device; during subsequent embedding, the embedding slurry generates heat during the solidification process, causing the wax to melt and flow out through the channel; a sink 17 is opened at the position corresponding to the through hole 15 on the side of the base 1 away from the embedding ring 2. The diameter of the sink 17 is larger than the diameter of the through hole 15, so that the melted wax will collect in the sink 17 for collection.

[0043] The implementation principle of a bracket embedding tool in an embodiment of the present application is as follows: during use, first insert the bottom end of the main runner of the gating device into the insertion slot 16 to complete the positioning of the gating device; then, sleuth the embedding ring 2 on the base 1 and make the limiting ring 12 snap into the limiting slot 21 to complete the positioning of the embedding ring 2; then pour embedding slurry into the embedding ring 2, and the heat generated during the solidification process of the slurry causes the melted wax to flow out from the through hole 15.

[0044] Embodiment 2

[0045] Refer to Figure 4 , the difference between this embodiment and Embodiment 1 is that the cross-section of the limiting ring 12 is in the shape of a trapezoidal table.

[0046] The above are all the preferred embodiments of the present application. Without limiting the protection scope of the present application accordingly, therefore: all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
