DETAILED DESCRIPTION

[0040] 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.

[0041] like Figures 1 to 7 As shown:

[0042] Embodiment 1: The present invention provides a processing and production device for a denture model, comprising:

[0043] The lower mold mechanism 1 comprises a lower mold assembly 11 and a lifting assembly 12 which is slidably mounted on the lower mold assembly 11;

[0044] The tooth positioning mechanism 2 includes a positioning frame assembly 21 rotatably connected to the lifting assembly 12, a magnetic stone assembly 22 slidably embedded in the positioning frame assembly 21, and a connecting assembly 23 rotatably embedded in the positioning frame assembly 21; wherein the lifting assembly 12 is installed on the lower mold assembly 11 and can slide up and down along the lower mold assembly 11 to adjust the height of the tooth positioning mechanism 2; the positioning frame assembly 21 is rotatably connected to the lifting assembly 12 to support and position the tooth model or implant; the magnetic stone assembly 22 is installed on the positioning frame assembly 21 to absorb the metal implant to ensure that it remains stable when the plaster is poured;

[0045] The lower mold assembly 11 includes a lower mold base 111, and a mold groove 112 is provided on the upper side of the lower mold base 111; wherein, the mold groove 112 is provided on the upper side of the lower mold base 111 for placing plaster or other pouring materials, and the mold groove 112 is provided on the upper side of the lower mold base 111 for placing plaster or other pouring materials to form an initial model of the denture;

[0046] The lifting assembly 12 includes a shaft frame 121 and a spring 122, and a U-shaped connecting rod 123 is fixedly connected to the lower end of the shaft frame 121; wherein the spring 122 is located at the lower side of the U-shaped connecting rod 123, and is used to drive the U-shaped connecting rod 123 to move upward to provide lifting power;

[0047] The positioning frame assembly 21 includes a positioning frame body 211, one side of the positioning frame body 211 is fixedly connected to a shaft rod 212, and a movable groove 213 is also provided on the positioning frame body 211; wherein the positioning frame body 211 is used to fix the tooth model or implant, and can rotate around the shaft frame 121 through the shaft rod 212, the shaft rod 212 is fixed to one side of the positioning frame body 211, and is used to support the positioning frame body and allow it to rotate, and the movable groove 213 is provided on the positioning frame body 211, and is used to install the magnetic stone assembly 22;

[0048] The magnetic stone assembly 22 includes a magnetic stone body 221, one end of which is fixedly connected to a connecting rod 222, and the outer side of the connecting rod 222 is slidably connected to a rubber ring 223; wherein the magnetic stone body 221 is the main body of the magnetic stone assembly 22, and is used to absorb metal implants or other magnetic materials, the connecting rod 222 is fixed to one end of the magnetic stone body 221, and is used to connect the magnetic stone body 221 to the movable groove 213, and the rubber ring 223 is slidably connected to the outer side of the connecting rod 222, and is used to limit the movement of the connecting rod 222, so as to ensure that the magnetic stone body 221 is stably adsorbed on the positioning frame body 211;

[0049] The U-shaped connecting rod 123 is limited and slidably embedded in the lower mold seat 111, and the spring 122 is located at the lower side of the U-shaped connecting rod 123 and drives the U-shaped connecting rod 123 to move upward. The shaft rod 212 is rotated and embedded in the shaft frame 121. The magnetic stone body 221 is limited and slidably embedded in the inside of the movable groove 213 through the connecting rod 222, and the rubber ring 223 can limit the connecting rod 222.

[0050] From the above, we can see that when using Figure 1, pour the plaster into the mold groove 112, and then place the metal implant 3 on the positioning frame body 211 in sequence. The metal implant 3 can be adsorbed by the magnetic stone body 221, and the positioning frame body 211 can be rotated around the shaft frame 121 through the shaft rod 212 by holding the connecting rod 222. When the positioning frame body 211 is rotated to the upper side of the lower mold seat 111, the positioning frame body 211 is moved downward, so that the shaft frame 121 drives the U-shaped connecting rod 123 to move and the spring 122 is compressed. After the positioning frame body 211 moves downward, the metal implant 3 will be inserted into the plaster. After the plaster is solidified, the positioning frame body 211 is released, and the spring 122 is reset to drive the U-shaped connecting rod 123 Move upward, so that the axis frame 121 drives the positioning frame body 211 to move upward. The upward movement of the positioning frame body 211 will cause the metal implant 3 to detach from the positioning frame body 211 and be fixed on the plaster. The plaster can be polished later by laser technology, and then the crown is fixed on the metal implant 3 to complete the production of the denture model; when the metal implant 3 is fixed on the plaster, pushing the handheld connecting rod 222 can make the magnetic stone body 221 move and detach from the metal implant 3, thereby avoiding the situation where the positioning frame body 211 moves upward and causes the metal implant 3 to detach. The friction force of the connecting rod 222 when moving can be increased by the rubber ring 223, thereby limiting the sliding of the magnetic stone body 221.

[0051] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that, a bracket 113 is fixedly connected to one side of the lower mold base 111, a support leg 114 is fixedly connected to the lower end of the bracket 113, and a threaded hole 115 is opened on the upper side of the lower mold base 111; wherein the threaded hole 115 is used to cooperate with the threaded rod 232 to achieve the fixing and adjustment of the positioning frame body 211;

[0052] The connecting assembly 23 includes a rotating head 231 , and one end of the rotating head 231 is fixedly connected to a threaded rod 232 .

[0053] Specifically, the rotating head 231 is rotatably embedded in the positioning frame body 211, and the threaded rod 232 can be rotatably embedded in the threaded hole 115; wherein the threaded rod 232 can be rotatably embedded in the threaded hole 115 to fix and adjust the position of the positioning frame body 211.

[0054] Specifically, the lower mold mechanism 1 also includes a buffer assembly 13, which includes a connecting column 131 and a spring 132. One end of the connecting column 131 is fixedly connected to a limiting ring 133, and the other end of the connecting column 131 is fixedly connected to a support plate 134; wherein the spring 132 is used to drive the movement of the support plate 134 and the connecting column 131 to provide a buffering effect.

[0055] Specifically, the connecting column 131 is limitedly slidably embedded on the lower mold base 111 , and the second spring 132 drives the support plate 134 to drive the connecting column 131 to move upward and be limited by the limiting ring 133 .

[0056] As can be seen from the above, the positioning frame body 211 can be supported by the bracket 113 and the support leg 114, so that the staff can place the metal implant 3 stably on the positioning frame body 211; when the positioning frame body 211 is located on the upper side of the lower mold seat 111, rotating the rotating head 231 can make the threaded rod 232 embedded in the threaded hole 115, so that the positioning frame body 211 moves down and is fixed on the upper side of the lower mold seat 111; when the positioning frame body 211 is located on the upper side of the lower mold seat 111, the support plate 134 and the spring 132 can play a supporting and buffering role.

[0057] Embodiment 3: This embodiment is basically the same as the previous embodiment, except that the lower mold mechanism 1 further includes a demolding assembly 14 and a pushing assembly 15. The demolding assembly 14 includes a push plate 141, and the lower end of the push plate 141 is fixedly connected to a trapezoidal block 142; the pushing assembly 15 includes an oblique push block 151, and one end of the oblique push block 151 is fixedly connected to a pushing rod 152; wherein, the trapezoidal block 142 has a trapezoidal cross-section, which is used to provide additional support and force transmission during the pushing process, and the oblique push block 151 is provided with an inclined surface, when it is moved, it can generate a forward driving force and make the trapezoidal block 142 move upward, so as to help the push plate 141 push the plaster model out of the mold groove 112, and the operator can apply force to move the oblique push block 151 through the pushing rod 152.

[0058] Specifically, the push plate 141 and the trapezoidal block 142 are both limited and slidably embedded in the mold groove 112, and the inclined push block 151 is limited and slidably embedded in the lower mold seat 111. Moving the inclined push block 151 can drive the trapezoidal block 142 to move upward; wherein, the push plate 141 and the trapezoidal block 142 can both slide in a limited manner on the mold groove 112.

[0059] As can be seen from the above, pushing the push rod 152 laterally can move the oblique push block 151, and the movement of the oblique push block 151 can make the trapezoidal block 142 drive the push plate 141 to move upward, and the upward movement of the push plate 141 will make the gypsum detach from the mold groove 112, thereby completing the demoulding.
