As shown in fig. 1 and fig. 2, in the present embodiment, a first molding cavity 311 is formed in a first mold 310, the first molding cavity 311 is connected with a mandibular frame 220 in a matching manner, the bottom of the mandibular frame 220 is clamped in the first molding cavity 311 of the first mold 310, the mandibular frame 220 is placed in the first mold 310, and then the gypsum mixture is smeared in the first molding cavity 311 to obtain a gypsum layer 40, so that the gypsum mixture can better fill the first mold 310, and in a specific operation process, the mandibular frame 220 needs to be fixed in the first mold 310 appropriately to avoid shifting or rotating when gypsum is smeared. Then adding the gypsum mixture into water according to a certain proportion, stirring uniformly, smearing the gypsum in the first mould 310 by using a scraping plate or a brush, gently vibrating the first mould 310 to remove bubbles and enable the gypsum mixture to fully fill the whole first mould 310, and obtaining the gypsum layer 40 after the gypsum is solidified.

As shown in fig. 1 and 2, the first mold 310 in the present embodiment includes: the bottom plate 312, the flange 313 and the opening 314, the bottom plate 312 is mutually abutted with the bottom of the mandibular frame 220, the bottom plate 312 and the flange 313 are integrally formed, the size and shape of the bottom plate 312 are matched with the appearance of the mandibular model 120, the flange 313 is arranged on the edge of the upper surface of the bottom plate 312, the flange 313 surrounds to form a first forming inner cavity 311, the flange 313 can prevent the gypsum layer 40 from overflowing to generate unnecessary waste, the mandibular frame 220 is clamped in the first forming inner cavity 311, the opening 314 is arranged on one side of the first forming inner cavity 311, and the mandibular frame 220 enters the first forming inner cavity 311 through the inclined opening 316, so that the mandibular frame 220 is easier to put into the first die 310.

As shown in fig. 1 and 2, in this embodiment, a stopper 315 is disposed at the opening 314, the stopper 315 and the first mold 310 are integrally formed, and the stopper 315 abuts against the mandibular frame 220 to limit the mandibular frame 220. The cavity formed by stop 315 and flange 313 matches the shape of mandibular rest 220 so that gypsum layer 40 does not overflow.

The flange 313 in this embodiment is provided with a bevel 316 on the side of the first molding cavity 311 for limiting the dental model 10. The curvature of the bezel 316 matches the shape of the mandibular model 120, and the bezel 316 is used to limit the mandibular model 120.

As shown in fig. 3, the intersection of the first mold half 321 and the second mold half 322 in this embodiment is provided with a logo line 330. The sign 330 is primarily intended to assist the operator in more accurately controlling the amount and location of gypsum injected during the process of injecting and shaping the gypsum mixture. By means of the marking 330, the operator can determine the desired injection height and position of the gypsum mixture as needed to ensure that the shape and size of the product meets the requirements.

The draft angle of the first die 310 in this embodiment is 4 degrees. The draft angle refers to an angle formed by the inner wall of the first mold 310 relative to the bottom of the first mold 310. The angle is generally oblique to the direction of opening of the first mold 310 and serves to create some slight clearance and cushioning between the first mold 310 and the gypsum layer 40 to facilitate removal of the first mold 310. Without the draft angle, it is likely to cause the gypsum layer 40 to become stuck or damaged when removed from the first mold 310. The magnitude of the draft angle will generally vary according to the specific situation, and if the draft angle is too small, the first mold 310 may not be removed smoothly; if the draft angle is too large, imperfections or quality instabilities may result in the surface of the article. Accordingly, in designing the first mold 310, it is necessary to select an appropriate draft angle and perform adequate testing and verification according to specific requirements and characteristics of the article.

The material of the second mold 320 in this embodiment is a transparent material or a semitransparent material. The transparent or translucent material allows the operator to more clearly see the position and condition of the gypsum layer 40 within the second mold 320, as well as the fill and distribution of the gypsum layer within the second mold 320, thereby facilitating adjustment and control. In addition, the transparent or translucent material may also check for bubbles and other imperfections in the second mold 320 to ensure that the quality of the gypsum layer 40 is more consistent and reliable.

The first mold 310 in this embodiment is provided with groove lines. The groove texture may increase the friction of the first mold 310 by requiring it to be wetted during use and then gently shaken before the gypsum liquid flows into the first mold 310 to ensure that the gypsum is evenly distributed throughout the first mold 310. If the surface of the first mold 310 is smooth, then gypsum can easily flow through and form bubbles or voids at one time, resulting in a product surface that is not smooth or has sharp corners. The texture can increase the roughness of the surface of the first mold 310, so that the first mold 310 has a certain friction force, and can help the gypsum to be uniformly distributed in the first mold 310. After the gypsum layer 40 is hardened in the first mold 310, the first mold 310 needs to be removed. If the surface of the first mold 310 is completely smooth, it is difficult to remove because the first molds 310 are closely adhered to the surface of the gypsum layer 40. The texturing may increase the complexity of the surface of the first mold 310, thereby making the first mold 310 easier to remove. And some gypsum first mold 310 designs include texturing and patterns to increase their aesthetic and visual appeal, making it more realistic and attractive in appearance.

As shown in fig. 1, the dental model fixing jaw frame assembly in this embodiment further includes a limiting plate 50, and the limiting plate 50 is disposed outside the dental model 10 and is used for fixing the dental model 10. The limiting plates 50 disposed around the jaw frame body 20 are mainly used for controlling the position of the dental model 10, and since the dental model 10 is placed on the gypsum layer 40 which is not completely solidified, the flow range of the gypsum mixture can be ensured and the dental model 10 can not be shifted by placing the limiting plates 50.

As shown in fig. 4, the upper jaw frame 210 and the lower jaw frame 220 in this embodiment are detachably connected. The upper jaw frame 210 and the lower jaw frame 220 can respectively carry the dental model 10 of the upper jaw and the lower jaw, and oral cavity scanning can be conveniently performed by disassembling. The oral cavity scanning can rapidly obtain high-precision oral cavity three-dimensional data, can be used for digitally designing and manufacturing dental crowns, dental sleeves, orthodontics and the like, is convenient for dentists to detect and diagnose oral cavities, and makes a diagnosis and treatment scheme for dentists to use, can realize fine tooth adjustment and corrective treatment, and can be rapidly disassembled and replaced.

As shown in fig. 4, the mandibular frame 220 in this embodiment is provided with a fixing base 230. The fixing base 230 can stably fix the jaw frame body 20 to prevent it from shaking or sliding, thereby improving the fixing efficiency of the dental model 10. The working efficiency and the precision of the dental treatment can be greatly improved.
