Description

Technical Field

[0001] This utility model relates to the field of dental prosthesis technology, and in particular to a dental prosthesis manufacturing mold. Background Technology

[0002] Dentures, commonly known as "false teeth," are similar to how "prosthetic legs" or "prosthetic limbs" are called "prosthetics." "Dentals" refers to teeth that fulfill their "duties" for humans. Medically, it's a general term for restorations made after partial or complete loss of the upper and lower jaw teeth. With economic development, people are increasingly valuing oral health and aesthetics, leading to higher demands for dental care and thus driving the growth of the dental industry.

[0003] In application CN202223591205.0, the device is fixed and installed in the position of the fixed frame assembly 2 through the fixing hole 201. The imprinting groove assembly 3 is taken out and a sample is taken in the patient's mouth. Then the imprinting groove assembly 3 is snapped into place. The denture material is placed in the surrounding plate 7 and the platform 6. The hydraulic cylinder 5 is started to push the denture material to the inner wall of the imprinting groove assembly 3 for compression molding. When the platform 6 is driven by the hydraulic cylinder 5 to compress and mold the denture material in the imprinting groove assembly 3, the compression intensity of the denture material by the platform 6 cannot be controlled, which can easily cause the imprinting paste in the imprinting groove assembly 3 to deform and reduce the denture molding accuracy. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies that cannot control the compressive strength of the control plate on the denture material, which can easily lead to deformation of the imprinting paste in the imprinting groove assembly and reduce the denture forming accuracy. Therefore, this invention proposes a denture manufacturing mold.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Design a dental prosthesis manufacturing mold, including a base plate, a slide rail frame fixedly connected to the upper end of the base plate, a movable plate slidably connected to the slide rail frame, an electric telescopic rod for driving the movable plate to move vertically connected to the upper end of the slide rail frame, a limiting mechanism connected to the upper end of the base plate, an imprinting groove mechanism inserted into the limiting mechanism, and an extrusion mechanism for extruding and molding materials connected to the movable plate.

[0007] The extrusion mechanism includes a pressure plate with both ends of the pressure plate penetrating the movable plate. Anti-detachment blocks are fixedly connected to both ends of the pressure plate. A protrusion block is fixedly connected to the upper end of the pressure plate. A pressure sensor is fixedly connected to the lower surface of the movable plate, and the pressure sensor can contact the protrusion block.

[0008] Preferably, an anti-slip pad is fixedly connected to the bottom end of the base plate.

[0009] Preferably, the pressure plate and the protrusion are an integral structure.

[0010] Preferably, the limiting mechanism includes a retaining seat, which is fixedly connected to the upper end of the base plate. A first connecting rod is engaged with the retaining seat, and a groove seat is fixedly connected to the upper end of the first connecting rod. An imprinting groove mechanism is inserted into the groove seat.

[0011] Preferably, the bottom end of the card holder is connected to a misalignment mechanism, the misalignment mechanism includes a second connecting rod, the bottom end of the groove seat has a through hole, the upper end of the through hole has a groove, the second connecting rod passes through the through hole, and the upper end of the second connecting rod is fixedly connected to a push block, the push block cooperates with the groove.

[0012] Preferably, a fixing plate is fixedly connected to the bottom end of the second connecting rod.

[0013] The dental prosthesis manufacturing mold proposed in this utility model has the following advantages:

[0014] After the pressure plate contacts the denture material, it slides upward. The pressure plate drives the protrusion to move. After the protrusion moves upward, it contacts the pressure sensor. During the process of the pressure plate squeezing the denture material, the protrusion squeezes the pressure sensor. The pressure sensor detects the squeezing intensity of the pressure plate on the denture material, avoiding excessive squeezing intensity that could cause deformation of the printing paste in the printing groove mechanism, thereby improving the manufacturing accuracy of the denture.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1: Refer to Figure 1-2 A dental prosthesis manufacturing mold includes a base plate 1, an anti-slip pad (rubber pad) fixedly connected to the bottom end of the base plate 1, a slide rail frame 2 fixedly connected to the upper end of the base plate 1, a movable plate 3 slidably connected to the slide rail frame 2, an electric telescopic rod 4 for driving the movable plate 3 to move vertically connected to the upper end of the slide rail frame 2, a limiting mechanism 5 connected to the upper end of the base plate 1, an imprinting groove mechanism 6 inserted into the limiting mechanism 5, and an extrusion mechanism 7 for extruding and molding materials connected to the movable plate 3.

[0022] The extrusion mechanism 7 includes a pressure plate 71, with both ends of the pressure plate 71 penetrating the movable plate 3. Both ends of the pressure plate 71 are fixedly connected to anti-detachment blocks 72. The upper end of the pressure plate 71 is fixedly connected to a protrusion block 73. The pressure plate 71 and the protrusion block 73 are an integral structure. The lower surface of the movable plate 3 is fixedly connected to a pressure sensor 74, which can contact the protrusion block 73.

[0023] Work process:

[0024] The imprinting groove mechanism 6 is removed and a sample is taken from the patient's mouth. Then, the imprinting groove mechanism 6 is inserted into the limiting mechanism 5. Denture material is placed in the imprinting groove mechanism 6. The electric telescopic rod 4 is powered on and started. After the electric telescopic rod 4 is started, it drives the movable plate 3 to move downward. The movable plate 3 drives the pressure plate 71 to move downward. After the pressure plate 71 moves downward a certain distance, it contacts the denture material in the imprinting groove mechanism 6. The movable plate 3 continues to move downward. After the pressure plate 71 contacts the denture material, it slides upward. The pressure plate 71 drives the protrusion 73 to move. After the protrusion 73 moves upward, it contacts the pressure sensor 74. During the process of the pressure plate 71 squeezing the denture material, the protrusion 73 squeezes the pressure sensor 74. When the pressure value detected by the pressure sensor 74 reaches the set value in the controller, the controller controls the electric telescopic rod 4 to move the movable plate 3 upward to reset. The pressure sensor 74 detects the squeezing intensity of the pressure plate 71 on the denture material to avoid excessive squeezing intensity causing deformation of the imprinting paste in the imprinting groove mechanism 6, thereby improving the manufacturing accuracy of the denture and reducing subsequent processing steps.

[0025] Example 2: In Example 1, when the imprinting groove mechanism 6 is fixed by the limiting mechanism 5, it is inconvenient to clean the limiting mechanism 5. (Refer to...) Figure 3-4 As another preferred embodiment of this utility model, the difference from embodiment 1 is that the limiting mechanism 5 includes a card seat 51, the card seat 51 is fixedly connected to the upper end of the base plate 1, a first connecting rod 52 is engaged on the card seat 51, a groove seat 53 is fixedly connected to the upper end of the first connecting rod 52, and an imprinting groove mechanism 6 is inserted into the groove seat 53. When cleaning the groove seat 53, the first connecting rod 52 is separated from the card seat 51, the first connecting rod 52 drives the groove seat 53 to move, and the groove seat 53 is removed to facilitate cleaning of the groove seat 53.

[0026] Example 3: In Example 2, because the imprinting groove mechanism 6 is placed inside the groove seat 53, it is inconvenient to remove the imprinting groove mechanism 6 after the denture is made, thus making it inconvenient to remove the denture. (Refer to...) Figure 4 As another preferred embodiment of this utility model, the difference from embodiment 1 is that the bottom end of the card holder 51 is connected to a misalignment mechanism 8. The misalignment mechanism 8 includes a second connecting rod 82. The bottom end of the groove seat 53 is provided with a through hole 81, and the upper end of the through hole 81 is provided with a groove. The second connecting rod 82 passes through the through hole 81. The upper end of the second connecting rod 82 is fixedly connected to a push block 83, which cooperates with the groove. The bottom end of the second connecting rod 82 is fixedly connected to a fixing plate 84. Pushing the fixing plate 84 upward pushes the second connecting rod 82, which in turn pushes the push block 83 upward. The push block 83 pushes the imprinting groove mechanism 6 upward. After being pushed, the imprinting groove mechanism 6 moves upward and is misaligned with the groove seat 53, making it convenient to remove the imprinting groove mechanism 6, thereby facilitating the removal of the denture.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
