Description

Technical Field

[0001] The invention relates to the field of denture model manufacturing devices, in particular to a molding and manufacturing device for denture models. Background Art

[0002] Denture models can accurately reflect the shape, position, and arrangement of the patient's teeth in the mouth, and reflect the height, width, and shape of the remaining alveolar ridges in the mouth, so that doctors can design denture types based on denture models. For denture technicians, denture models are the most direct basis for making dentures. When making fixed dentures, the shape of the abutment teeth on the model determines the shape of the inner crown of the crown; when making removable partial dentures, the model can help technicians determine the support structure of the denture.

[0003] At present, the production of denture models is mostly achieved through the infusion process, that is, the mold is matched with the mold of the patient's teeth, and the production material is melted and injected into the mold. However, there are still some defects in the existing denture model molding and manufacturing equipment. For example, after the molten raw material is injected into the mold, it is necessary to wait for it to cool and form. The natural cooling time is too long, and forced air cooling can only achieve rapid cooling of the surface. Although there are some solutions that use circulating water cooling, this solution requires the cooling water channels inside the mold to be interconnected and to achieve comprehensive coverage as much as possible. Due to the limitation of the mold structure, the mold manufacturing cost is relatively high. At the same time, the production material itself contains a certain amount of moisture. At the same time, during the melting and stirring process, the internal gas is difficult to completely remove.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Example 1: Please refer to the attached Figure 1 -Attached Figure 6 The embodiment of the present invention provides a molding and manufacturing device for a denture model, including an injection molding cabinet 1, wherein an upper chamber 101 and a lower chamber 102 are provided in the injection molding cabinet 1, an air pump 2 is provided outside, and a water level regulating device is provided in the lower chamber 102. The water level regulating device is driven by the air pump 2 to change the volume of the lower chamber 102 so as to adjust the water level of the coolant in the lower chamber 102. A heat spreader 3 is provided between the upper chamber 101 and the lower chamber 102, and the front and rear walls of the heat spreader 3 are respectively fixedly connected to the front and rear inner walls of the injection molding cabinet 1, and a gap is left between the left and right walls of the heat spreader 3 and the left and right inner walls of the injection molding cabinet 1, and the upper chamber 101 and the lower chamber 102 are connected. The two chambers 102 and 103 are connected through a gap. A heat-conducting column 4 is fixedly connected to the bottom wall of the heat spreader 3. The heat-conducting column 4 is immersed in the coolant in the lower chamber 102. A lower mold 5 is fixed to the upper wall of the heat spreader 3. An upper mold 6 is arranged above the lower mold 5. A lifting device 7 is fixedly connected to the top of the upper chamber 101. A melting device is arranged below the lifting device 7. The melting device is used to melt and process the injection molding raw materials. The bottom discharge end of the melting device is embedded in the injection port of the upper mold 6. The melting device is driven down by the lifting device 7 to make the upper mold 6 and the lower mold 5 engage with each other, and the gas in the melting device is extracted and injected into the melting device by the air pump 2.

[0029] The gas in the melting device is continuously extracted by the air pump 2, so that the air pressure in the melting device is reduced, thereby reducing the boiling point of water on the one hand, so that the water in the raw material can evaporate quickly, and on the other hand, the air is continuously discharged to form a state close to vacuum, thereby preventing air from entering the molten raw material. Through the cooperation of the air pump 2 and the water level regulating device, after the raw material is injected into the mold, the mold is initially cooled by the air flow generated by the heat plate 3 and the air pump 2, so that the outer layer of the molten raw material in the mold is initially cooled and hardened, and then the water level regulating device is driven by the air pump 2 to raise the water level of the coolant, so that the mold is immersed in the coolant, providing a lower temperature environment for the cooling process, thereby improving the efficiency of heat exchange.

[0030] A loading port 8 is provided on the left side of the injection molding cabinet 1, and a baffle 9 is sleeved and slidably connected at the bottom of the loading port 8. The baffle 9 is driven up and down by an electric push rod 10 to change the bottom height of the loading port 8. A partition 15 and a partition 2 16 are respectively provided from top to bottom in the upper chamber 101. The partition 15 and the partition 2 16 are fixedly connected by a support 17. The front and rear walls of the partition 15 and the partition 2 16 are slidably connected with a slide rail 18, and the sliding direction is horizontal. The outer wall of the slide rail 18 is slidably connected to the front and rear inner walls of the upper chamber 101, and the sliding direction is vertical.

[0031] When loading, the lifting device 7 first lifts the melting device to a suitable position, and then the structure composed of the partition 15, the partition 2 16 and the support 17 can be pulled out from the loading port 8, and the proportioned raw materials can be placed in the melting device. At the same time, the electric push rod 10 drives the baffle 9 to descend, so that the lower mold 5 is exposed, so that the rubbing mold of the patient's teeth can be placed in the lower mold 5. Before the water level of the coolant rises, the electric push rod 10 drives the baffle 9 to rise, and the bottom end height of the loading port 8 is increased to prevent the coolant from overflowing from the loading port 8.

[0032] One end of an air pipe 11 is passed through and fixedly connected to the cabinet wall on the side opposite to the feeding port 8 of the injection molding cabinet 1. The other end of the air pipe 11 is communicated with the air inlet end of the air pump 2, and an air valve 12 is arranged on the pipe body of the air pipe 11. The air inlet end and the air outlet end of the air pump 2 are respectively communicated with the outside world through pipes 13, and valves 14 are arranged on the pipe bodies of the two pipes 13. The melting device includes a melting tank 19, the outer wall of the melting tank 19 passes through the partition 15 and is fixedly connected thereto, the discharge end of the melting tank 19 passes through the partition 2 16 and is embedded in the injection port of the upper mold 6, the bottom wall of the upper mold 6 is clamped and fixed to the bottom wall of the partition 2 16, the exhaust port at the top of the melting tank 19 is connected to the air inlet end of the air pump 2 through the air pipe 2 20, and an air valve 21 is provided on the tube body of the air pipe 20, the air inlet at the top of the melting tank 19 is connected to the air outlet end of the air pump 2 through the air pipe 3 22, and an air valve 3 23 is provided on the tube body of the air pipe 3 22.

[0033] It should be noted that the melting tank 19 not only has the function of carrying the raw materials, but also has a heating function so that the raw materials inside it are heated to a molten state.

[0034] The parts of the second air pipe 20 and the third air pipe 22 located in the injection molding cabinet 1 are both made of flexible and retractable materials to achieve the lifting and lowering changes of the melting tank 19.

[0035] The water level regulating device includes a piston 28, the outer wall of the piston 28 is slidably connected to the inner wall of the lower chamber 102, and a sealing structure is formed at the contact point between the two. The lower chamber 102 is divided into chamber one 103 and chamber two 104 by the piston 28. Chamber one 103 is connected to the upper chamber 101. The air inlet of chamber two 104 is connected to the air outlet end of the air pump 2 through air pipe four 29, and an air valve four 30 is provided on the tube body of air pipe four 29. The air outlet of chamber two 104 is connected to the air inlet end of the air pump 2 through air pipe five 31, and an air valve five 32 is provided on the tube body of air pipe five 31.

[0036] It should be noted that in the entire equipment, whether it is the step of evacuating the melting tank 19, inflating the melting tank 19 to increase the air pressure to increase the pressure for raw material injection, or driving the water level regulating device to operate, as well as extracting air from the injection molding cabinet 1 and cooperating with the feeding port 8 to form an airflow to cool the mold, all are achieved through the air pump 2. By opening and closing different air valves and valves, different effects of the air pump 2 have been achieved. Of course, the selection and power of the air pump 2 also need to meet the requirements.

[0037] A stirring motor 24 is fixedly connected to the middle of the tank cover of the melting tank 19, and the output end of the stirring motor 24 is fixedly connected to the stirring shaft 25 in the melting tank 19. The bottom end of the stirring shaft 25 is fixedly connected to a stirring blade 26. A drainage hood 27 is also fixedly connected to the melting tank 19. The drainage hood 27 is a cylindrical structure that passes through from top to bottom. A plurality of liquid outlets 2701 are symmetrically opened in the middle of the hood body of the drainage hood 27, and the stirring blades 26 are located between the liquid outlets 2701.

[0038] When in use, the raw material is chopped by the rotating stirring blade 26 to form smaller particles, thereby improving the melting efficiency. At the same time, the melted raw material is mixed with the unmelted small particles in the drainage cover 27 to form irregular vortex and negative pressure, and is sucked from the bottom of the melting tank 19, lifted into the drainage cover 27 for full mixing, and then continuously thrown out under the action of centrifugal force, and then ejected from the liquid outlet 2701 and returned to the melting tank 19. The raw material that has returned to the melting tank 19 is sucked from the bottom again and lifted into the drainage cover 27, so as to circulate repeatedly between the melting tank 19 and the drainage cover 27.

[0039] The coordination between the stirring blade 26 and the drainage hood 27 allows the raw materials to be evenly mixed and flowed during the melting process, which on the one hand improves the uniformity of the raw material ratio. On the other hand, the molten raw materials are constantly stirred, flowed, and circulated inside and outside the drainage hood 27, so that the gas mixed therein can be discharged, further reducing the probability of bubble generation.

[0040] The outer wall of the lifting device 7 is fixedly connected to the top of the upper chamber 101, and the output end of the lifting device 7 is fixedly connected to a bracket 701, and the bottom end of the bracket 701 is slidably connected to the upper wall of the partition 15.

[0041] The outer wall of the upper mold 6 and the outer wall of the lower mold 5 are both provided with a plurality of liquid guide holes 38. When the water level of the coolant in the lower chamber 102 rises, the upper mold 6 and the lower mold 5 are immersed in the coolant, and part of the coolant is poured into the liquid guide holes 38. The coolant is poured into the liquid guide holes, which has an effect similar to circulating water cooling, further improving the cooling efficiency.

[0042] Example 2: Please refer to the attached Figure 7 -Attached Figure 8 , this embodiment provides another water level regulating device.

[0043] The water level regulating device includes an air bag 33, which is located in the lower chamber 102. The air inlet of the air bag 33 is connected to the air outlet of the air pump 2 through an air pipe 6 34, and an air valve 6 35 is provided on the tube body of the air pipe 6 34. The air outlet of the air pump 2 is connected to the air inlet of the air pump 2 through an air pipe 7 36, and an air valve 7 37 is provided on the tube body of the air pipe 7 36.

[0044] The air pump 2 injects air into the airbag 33 through the air pipe 6 34, and the airbag 33 expands, which reduces the actual volume of the lower chamber 102, thereby increasing the liquid level of the coolant inside the lower chamber 102. Conversely, the air pump 2 extracts the air in the airbag 33 through the air pipe 7 36, which restores the actual volume of the lower chamber 102, thereby reducing the liquid level of the coolant inside the lower chamber 102.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
