[0026] The present utility model provides the following description with reference to the accompanying drawings to help comprehensively understand various embodiments of the present utility model as defined by the claims and their equivalents. The description includes various specific details to help understanding, but these details should be regarded as just exemplary. Therefore, those skilled in the art will realize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the present utility model.

[0027] In the description of the present utility model, when the orientation description such as the orientation or position relationship indicated by up, down, front, back, left, right, etc. is based on the orientation or position relationship shown in the drawings, it is only for the convenience of describing the present utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present utility model.

[0028] It should be understood that when one element (for example, a first element) is "connected" to another element (for example, a second element), the element can be directly connected to the other element, or there can be an intervening element (for example, a third element) between the element and the other element.

[0029] The embodiment of the present utility model provides a waterproof medical dental brace forming die, as shown in the figure, comprising: Figures 1-6

[0030] The front die assembly comprises a front die insert 102, and the front die insert 102 is provided with a first forming cavity 103;

[0031] The rear die assembly comprises a rear die insert 105, a forming insert 106 arranged on the rear die insert 105, and an ejection assembly 107 connected with the forming insert 106, and the rear die insert 105 is provided with a second forming cavity 108, and the forming insert 106 is provided with a third forming cavity 109 for forming a dental brace base;

[0032] The positioning insert 201 is arranged below the front die insert 102 and is connected with the forming insert 106, and the positioning insert 201 is used for fixing the dental brace side fitting 401 on the forming insert 106.

[0033] ​The split back mold forming structure of the back mold core 105 and the forming insert 106 facilitates the forming insert 106 to be lifted up by the ejection assembly 107, so that the lower part of the mouthguard base can be demolded first, facilitating subsequent demolding without interference and damage to the product, and also facilitating cleaning and processing. The positioning insert 201 is arranged below the front mold core 102 and connected with the forming insert 106, so that when the mold is closed, the mouthguard side accessory 401 can be pressed onto the forming insert 106 to be fixed, effectively preventing the mouthguard side accessory 401 from floating and shifting during the forming process, ensuring the accurate alignment of the mouthguard side accessory 401, thereby ensuring the overall structural precision and appearance quality of the mouthguard and improving the qualification rate of the product.

[0034] In some embodiments, as shown in Figure 5 The positioning insert 201 includes an upper fixed part 202 connected with the front mold core 102 and a pressing part 203 for pressing the mouthguard side accessory 401.

[0035] The connection of the upper fixed part 202 with the front mold core 102 ensures the stability of the positioning insert 201, avoiding the displacement of the mouthguard side accessory 401 due to the loosening of the positioning insert 201; the pressing part 203 cooperates with the shape of the mouthguard side accessory 401, which can effectively press the mouthguard side accessory 401 firmly on the forming insert 106, preventing it from floating due to the flow of liquid silicone during the forming process, thereby ensuring the accurate alignment of the mouthguard side accessory 401.

[0036] Further, as shown in Figures 4-5 The positioning insert 201 further includes a lower fixed part 204 at the bottom thereof abutting against the forming insert 106, and the forming insert 106 has a fixed groove 205 for accommodating the lower fixed part 204.

[0037] The lower fixed part 204 makes the connection between the positioning insert 201 and the forming insert 106 more accurate, further preventing the positioning insert 201 from shifting or loosening during the forming process, further enhancing the stability of the mouthguard side accessory 401 during the forming process, ensuring that it always remains in an accurate position during the forming process, thereby improving the overall forming precision and quality of the mouthguard.

[0038] Still further, as shown in Figure 5 The pressing part 203 includes a first pressing block 206 and a second pressing block 207 gradually inclined outward from bottom to top.

[0039] The first pressing block 206 and the second pressing block 207 press the mouthguard side accessories 401 on both sides respectively, facilitating the simultaneous integral forming of the mouthguard side accessories 401 on both sides.

[0040] In some embodiments, as shown in Figures 3-4 A waterproof medical mouthguard forming mold further includes a overflow groove structure 301.

[0041] The overflow groove structure 301 effectively collects the excess silica gel material during the molding process, allows the silica gel to fully fill the entire molding cavity, improves the molding quality of the product, and reduces the rate of defective products caused by trapped air and other reasons.

[0042] Further, as shown in Figure 4 , the overflow groove structure 301 includes a first overflow groove 302 arranged on one side of the second molding cavity 108 and a second overflow groove 303 arranged on one side of the third molding cavity 109.

[0043] The first overflow groove 302 and the second overflow groove 303 are independent grooves arranged away from the liquid injection port end, which discharge the excess liquid silica gel at the end of each molding area, ensure uniform distribution of liquid during the molding process of the mouthpiece side fitting 401 and the main body part, further improve the molding precision, and facilitate subsequent cleaning of excess material.

[0044] Further, as shown in Figure 3 , the overflow groove structure 301 includes a third overflow groove 304 arranged on the front mold core 102, and the third overflow groove 304 is arranged along the edge of the first molding cavity 103.

[0045] The third overflow groove 304 is arranged along the edge of the first molding cavity 103, which not only can collect the overflowed silica gel, but also can conveniently remove the excess edge material after molding, ensuring the flatness of the product edge.

[0046] Further, as shown in Figure 3 , the overflow groove structure 301 further includes a fourth overflow groove 305 arranged on the positioning insert 201, and the fourth overflow groove 305 is arranged along the edge of the mouthpiece side fitting 401.

[0047] The fourth overflow groove 305 is arranged along the edge of the mouthpiece side fitting 401, which can collect the overflowed silica gel at the edge of the mouthpiece side fitting 401, and can also conveniently remove the excess edge material after molding, ensuring the flatness of the product edge.

[0048] In some embodiments, as shown in Figure 6 , the ejection assembly 107 includes a ejector rod 110 connected with the molding insert 106 and a guide sleeve 111 arranged on the rear mold core 105.

[0049] The ejector rod 110 can eject the molding insert 106 from the rear mold core 105 to realize demolding of the mouthpiece base, and the guide sleeve 111 can guide the movement direction of the ejector rod 110 to prevent the ejector rod 110 from deviating or shaking during the ejection process.

[0050] In some embodiments, as shown in Figure 4 , the second molding cavity 108 has a fixing block 112 for fixing the mouthpiece base.

[0051] The fixed block 112 prevents the displacement or deformation of the mouthpiece base during the molding process, thereby ensuring the overall structural accuracy and stability of the mouthpiece.

[0052] The terms and words used in the above description and claims are not limited to the literal meanings but are merely used by the applicant to enable a clear and consistent understanding of the present application. Accordingly, it should be apparent to those skilled in the art that the description of the various embodiments of the present application is provided only to explain the present application and is not intended to limit the present application as defined by the appended claims and their equivalents.
