Technical Field

[0001] This utility model relates to the field of dental prosthesis processing technology, specifically to a dental prosthesis impression structure. Background Technology

[0002] Dentures are artificial teeth that replace missing natural teeth; they are also called false teeth. Severe periodontal disease, dental caries, and trauma can cause partial or even complete loss of teeth. Tooth loss can affect facial appearance, speech, chewing function, and increase the burden on the digestive system. If not repaired in time, it can also lead to tilting and displacement of adjacent teeth, elongation of opposing teeth, and malocclusion. Partial tooth loss can be restored with fixed or removable dentures, while complete dentures can be used for total edentulism.

An insert plate is fixed inside the inner ring of the annular airbag. Multiple insert rods are evenly spaced on the bottom of the insert plate, with their lower ends inserted into the rod grooves. A positioning component is located on the top of the insert plate. The positioning component includes a vertical plate, the bottom of which is fixed to the top of the insert plate. A sliding groove is provided on the front of the vertical plate, and sliders are connected to both sides of the inner wall of the sliding groove. A push rod motor is mounted on the top of the slider and is fitted to the top wall of the vertical plate. A sliding opening is provided at the rear end of the vertical plate. This invention facilitates positioning, improves the stability during impression taking, and makes it easy to disassemble the positioning component for maintenance or replacement, saving disassembly time. It is highly practical and suitable for widespread application.

[0004] However, the above-mentioned technologies cannot solve the problem of small tooth volume located inside the mold and the shape of the denture being difficult to grasp, which makes it inconvenient to remove the processed denture from the mold during processing. Therefore, this utility model provides a demolding structure suitable for dentures. Utility Model Content

Beneficial effects

[0014] This invention provides a structure suitable for taking dental impressions. Compared with the prior art, it has the following advantages:

[0015] (1) The mold-taking structure combines a pair of molds during the casting process, and materials are injected into the pair of molds to form dentures.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4This utility model provides a technical solution: a structure suitable for taking impressions of dentures, including a vibrating box 1. The top of the vibrating box 1 has a pair of first sliding grooves 2. A vertical plate 3 is slidably connected to the pair of first sliding grooves 2 via a first sliding block. The top of the vibrating box 1 has a casting mechanism 4 for casting molds. The casting mechanism 4 includes: a casting assembly 5, disposed on the pair of vertical plates 3 for casting molds; the casting assembly 5 includes a second sliding groove 6, with molds 7 slidably connected to each of the pair of second sliding grooves 6; one of the molds 7 has a concave groove 8 on its side wall, and the other mold 7 has a concave strip 9 fixedly connected to its side wall; and a separation assembly 10, disposed on the vibrating box 1 for moving the pair of vertical plates 3. The separation assembly 10 includes an electric telescopic rod 11. 11 is fixed to the top of the vibration box 1 by the first fixing block. The telescopic end of the electric telescopic rod 11 is fixed to the concave block 12. The concave block 12 is rotatably connected to the opposite side walls by a pair of first rotating shafts. A pair of vertical plates 3 are provided with first through slots 14. One end of the pair of connecting rods 13 is rotatably connected to the pair of first through slots 14 by a second rotating shaft. When casting, the pair of molds 7 are combined, and materials can be injected into the pair of molds 7 to form dentures. The pair of molds 7 are lowered by the electric telescopic rod 11 to separate them, so that the dentures have a larger exposed area when separated, which makes it convenient for staff to take out the dentures and make impressions of the dentures. The molds 7 can be disassembled and can be assembled with denture molds 7 of different shapes.

[0024] In this embodiment, a set of third sliding grooves 15 are provided on the bottom wall of the vibration box 1. A pair of rectangular rods 16 are slidably connected to the set of third sliding grooves 15 through a set of third sliding blocks. The pair of rectangular rods 16 are respectively connected to the opposite side walls of the vibration box 1 through spring pieces. A circular through groove 17 is provided at the bottom of the vibration box 1. A motor 18 is fixedly connected to the bottom of the vibration box 1 through a pair of L-shaped rods. A Z-shaped rod 19 is provided at the output end of the motor 18. A waist-shaped hole block 20 is fixed between the opposite side walls of the pair of rectangular rods 16 through a pair of fixed rods. One end of the Z-shaped rod 19 is slidably connected in the waist-shaped hole block 20. By setting a click to drive the Z-shaped rod 19 to rotate, the waist-shaped hole block 20 can be driven to reciprocate, thereby causing the rectangular rods 16 and the spring pieces to cooperate to make the vibration box 1 vibrate. Thus, after the staff separates the pair of molds 7, the vibration can break the adhesion between the denture and the mold 7, which is caused by the denture being too firmly adhered to the mold 7.

[0025] In this embodiment, a spring-loaded telescopic rod 21 is fixedly connected to the side wall of the upright plate 3 via a second fixing block. A third fixing block 22 is fixedly connected to the telescopic end of the spring-loaded telescopic rod 21, and a limiting block 23 is fixedly connected to the bottom of the third fixing block 22. By setting the spring-loaded telescopic rod 21, the height of the limiting block 23 can be controlled. Thus, after the worker places the mold 7 in the second sliding groove 6, the limiting block 23 can restrict the mold 7 under the action of the contraction force of the spring-loaded telescopic rod 21, preventing the mold 7 from shaking. The contraction force of the spring-loaded telescopic rod 21 can remain stable when vibrating in the vibration box 1.

[0026] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0027] During operation, a pair of molds 7 are merged during molding, and material is injected into the molds 7 to form a denture. The pair of molds 7 are then lowered and separated by an electric telescopic rod 11, ensuring a larger exposed area of ​​the denture during separation. This facilitates easy removal and impression taking by the staff. The molds 7 are also detachable, allowing for the assembly of denture molds 7 of different shapes. A set click drives the Z-shaped rod 19 to rotate, which in turn drives the oblong hole block 20 to reciprocate. This, in turn, causes the rectangular rod 16 to engage with the spring plate, causing the vibration box 1 to produce... The vibration generates vibration, which can be used to separate a pair of molds 7 by the staff. This vibration can break the adhesion between the denture and the mold 7, which is so strong that it cannot be removed even after separation. The elastic telescopic rod 21 can control the height of the limiting block 23. After the staff places the mold 7 in the second sliding groove 6, the limiting block 23 can restrict the mold 7 under the contraction force of the elastic telescopic rod 21, preventing the mold 7 from shaking. The contraction force of the elastic telescopic rod 21 can keep the vibration stable when vibrating in the vibration box 1.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0029] During operation, a pair of molds are merged during molding to inject material into them and form a denture. The molds are then lowered and separated by an electric telescopic rod, ensuring a larger exposed area for easy removal and impression taking. The molds are also detachable, allowing for the assembly of different shaped molds. A set click drives a Z-shaped rod to rotate, which in turn moves a waist-shaped hole block back and forth. This movement, in turn, causes a rectangular rod and a spring plate to vibrate the vibrating chamber. After the molds are separated, the vibration breaks up any dentures that are too firmly attached to the molds to prevent removal. A spring-loaded telescopic rod controls the height of a limiting block, preventing wobbling when the mold is placed in the second sliding groove. The telescopic rod's contraction force maintains stability during vibration within the chamber.
