Description

Technical Field

[0001] This utility model relates to the field of zirconia ceramic block sintering technology, and more specifically, to a zirconia ceramic block sintering support. Background Technology

[0002] Zirconia ceramic blocks are typically used for fixed denture restorations. They are usually disc-shaped and are produced by high-temperature sintering of the shaped material. Currently, the zirconia ceramic block blanks are usually sintered by stacking and spreading the material, which requires the use of a firing support.

[0003] Uniform placement is a crucial step in ensuring that zirconia blanks are heated evenly, shrink uniformly, and that deformation and cracking are reduced during sintering. Therefore, to ensure the sintering pass rate of zirconia ceramic blocks, it is necessary to arrange the blanks at intervals during the placement process. Manually placing the blanks one by one and adjusting the corresponding spacing is time-consuming and affects sintering efficiency. Furthermore, during sintering, the restricted airflow direction can easily lead to uneven temperature distribution within the kiln, resulting in uneven quality of the finished products from the same batch.

[0005] To achieve the above objectives, this utility model provides a zirconia ceramic block sintering support, comprising: a kiln base, wherein guide wheels are symmetrically installed on the bottom of the kiln base;

[0006] A mounting section is provided above the kiln base;

[0007] A drive unit is mounted on the kiln base and drives the mounting unit.

[0008] A support portion, wherein the support portion is disposed within the placement portion, and the placement portion restricts the support portion;

[0009] A support portion is mounted on the kiln base and is used to support and stabilize the mounting portion;

[0010] The supporting part includes several firing trays disposed within the placement part for placing zirconia ceramic blocks, and several positioning grooves formed on the lower surface of the several firing trays, wherein...

[0011] The drive unit is driven, and the mounting unit is able to rotate under the support of the support unit;

[0012] The placement position of the zirconia ceramic blocks is determined by flipping over several of the aforementioned firing trays and using several of the aforementioned positioning grooves.

[0013] Furthermore, the placement part includes a placement plate disposed on the upper surface of the kiln base, three support rods fixed on the upper surface of the placement plate, a limiting ring fixed on the top of the three support rods, a limiting rod hinged to the limiting ring, a plurality of bearing blocks fixed at equal intervals on the limiting rods and the three support rods, and a plurality of limiting grooves respectively fixed on the lower surface of the plurality of firing plates and corresponding to the plurality of bearing blocks.

[0014] Several heating plates are arranged between the limiting rod and the three supporting rods, and several bearing blocks are respectively fitted and slidably inserted into several limiting grooves.

[0015] Furthermore, the placement part also includes a locking block fixed to the upper surface of the placement plate, a locking groove formed on the locking block and corresponding to the lower end of the limiting rod, a locking plate rotatably mounted on the locking block, and a control groove formed at the bottom of the locking plate.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0033] like Figure 1-5As shown, a zirconia ceramic block sintering support includes: a kiln base 1, wherein guide wheels 25 are symmetrically installed on the bottom of the kiln base 1;

[0034] Installation section 2, which is located above the kiln base 1;

[0035] A drive unit 3 is mounted on the kiln base 1 and drives the mounting unit 2.

[0036] The support part 4 is disposed within the placement part 2, and the placement part 2 restricts the support part 4;

[0037] Support part 5, which is installed on the kiln base 1 and is used to support and stabilize the mounting part 2;

[0038] The supporting part 4 includes several firing trays 6 disposed within the placement part 2 for placing zirconia ceramic blocks, and several positioning grooves 7 formed on the lower surface of the several firing trays 6, wherein...

[0039] The drive unit 3 is driven, and the mounting part 2 can rotate under the support of the support part 5;

[0040] The placement position of the zirconia ceramic blocks is determined by flipping several of the firing trays 6 and several of the positioning grooves 7.

[0041] In use, several firing trays 6 can be flipped over so that the positioning grooves 7 on the trays 6 face upwards. At this point, the operator can directly place the zirconia ceramic blocks to be sintered into the positioning grooves 7. Then, the firing trays 6 are stacked on top of each other to ensure they are level. Finally, the trays 6 containing the zirconia ceramic blocks are transferred to the placement section 2 and then flipped back to their original positions. At this point, all the zirconia ceramic blocks on the trays 6 are in place, ensuring uniform placement and improving the ease of use. Afterwards, the trays 6 containing the zirconia ceramic blocks are stably placed above the kiln base 1 via the placement section 2, with the trays stacked on top of each other and adjacent trays aligned. The space between the individual firing trays 6 provides good ventilation and heat conduction, facilitating the effective sintering of large quantities of zirconia ceramic blocks. Finally, the kiln base 1 is pushed and connected to the kiln by the guide wheels 25, and the zirconia ceramic blocks 6 are placed inside the kiln for sintering. During sintering, the drive unit 3 controls the placement unit 2 to rotate the zirconia ceramic blocks 6, ensuring that the zirconia ceramic blocks are heated evenly inside the kiln. This avoids local overheating or undercooling caused by uneven temperature distribution within the kiln, reduces thermal stress caused by temperature gradients in the zirconia ceramic blocks during sintering, improves sintering quality, reduces deformation and cracking, and allows the zirconia ceramic blocks to fully contact the hot airflow inside the kiln, improving heat conduction efficiency, shortening sintering time, and increasing production efficiency.

[0042] Optionally, the placement part 2 includes a placement plate 8 disposed on the upper surface of the kiln base 1, three support rods 9 fixed on the upper surface of the placement plate 8, a limiting ring 10 fixed on the top of the three support rods 9, a limiting rod 11 hinged to the limiting ring 10, a plurality of bearing blocks 12 fixed at equal intervals on the limiting rod 11 and the three support rods 9, and a plurality of limiting grooves 13 respectively fixed on the lower surface of the plurality of firing plates 6 and corresponding to the plurality of bearing blocks 12;

[0043] Several firing trays 6 are disposed between the limiting rod 11 and the three supporting rods 9, and several bearing blocks 12 are respectively fitted and slidably inserted into several limiting grooves 13. In use, several firing trays 6, on which zirconia ceramic blocks are placed and stacked, are sequentially placed between the three supporting rods 9 from top to bottom, ensuring that the limiting grooves 13 at the bottom of the firing trays 6 are aligned with the bearing blocks 12 on the three supporting rods 9. When the bearing blocks 12 on the three supporting rods 9 are inserted into the limiting grooves 13 at the bottom of the firing trays 6, the firing trays 6 are effectively restricted from moving. The three support rods 9 restrict the firing plates 6 to be placed between the three support rods 9 in sequence. Then, the limiting rod 11 is rotated to control the limiting rod 11 to be perpendicular to the placement plate 8. At this time, the bearing blocks 12 on the limiting rod 11 are inserted into the limiting grooves 13 on the firing plates 6, thereby ensuring the stability of the firing plates 6 in the placement part 2. The multiple firing plates 6 are stacked on each other, and there is space between two adjacent firing plates 6 to provide good ventilation and heat conduction, so as to facilitate the effective sintering of a large number of zirconia ceramic blocks.

[0044] Optionally, the placement part 2 further includes a locking block 14 fixed to the upper surface of the placement plate 8, a locking groove 15 formed on the locking block 14 and corresponding to the lower end of the limiting rod 11, a locking plate 16 rotatably mounted on the locking block 14, and a control groove 26 formed at the bottom of the locking plate 16. When several firing plates 6 are placed between several support rods 9 and the limiting rod 11 is rotated to further restrict the several firing plates 6, the lower end of the limiting rod 11 will be inserted into the locking groove 15. After the locking plate 16 is rotated to close the locking groove 15, the restriction on the lower end of the limiting rod 11 is completed, effectively improving the stability of the several firing plates 6 in the placement part 2.

[0045] Optionally, the mounting part 2 further includes a slot 17 formed on the locking block 14, and a locking block 18 fixed on the locking plate 16 and adapted to the slot 17. When the locking plate 16 is rotated to close the locking groove 15, the locking plate 16 undergoes a certain elastic deformation, so that the locking block 18 on the locking plate 16 can be smoothly engaged in the slot 17 on the locking block 14, thereby restricting the rotation of the locking plate 16 on the locking block 14 and preventing the locking plate 16 from rotating due to vibration, which would affect the limiting effect on the limiting rod 11.

[0046] Optionally, the drive unit 3 includes a geared motor 19 mounted on the lower surface of the kiln base 1, a rotating shaft 20 rotatably mounted inside the kiln base 1, with one end fixedly connected to the output end of the geared motor 19 and the other end fixedly connected to the mounting plate 8. When the kiln base 1 moves into the kiln via the guide wheel 25 to sinter several zirconia ceramic blocks, the geared motor 19 is driven to work, thereby controlling the rotating shaft 20 to drive the mounting unit 2 to rotate stably. This ensures that the zirconia ceramic blocks on the several firing plates 6 in the mounting unit 2 are heated and shrink evenly, reducing deformation and cracking, reducing thermal stress caused by uneven temperature distribution, and effectively improving the sintering quality of the zirconia ceramic blocks.

[0047] Optionally, the upper surfaces of the plurality of firing trays 6 are fixedly connected in a ring array with a plurality of limiting protrusions 21 corresponding to the plurality of limiting grooves 13. When the plurality of firing trays 6 are flipped and stacked, the limiting protrusions 21 on the upper firing tray 6 can be engaged in the adjacent limiting grooves 13 on the lower firing tray 6 to ensure the stability of the two adjacent firing trays 6 after they are stacked together, and to improve the stability of the plurality of firing trays 6 on which zirconia ceramic blocks are placed during transportation.

[0048] Optionally, the support part 5 includes an annular assembly groove 22 opened on the upper surface of the kiln base 1, a plurality of support wheels 23 installed in the annular assembly groove 22 in a circular array, and a guide groove 24 opened on the lower surface of the mounting plate 8.

[0049] The support wheels 23 abut against the inner wall of the guide groove 24. During the rotation of the mounting part 2 controlled by the drive unit 3, the support wheels 23 can effectively support the mounting part 2, preventing the mounting part 2 from directly contacting the kiln base 1 and avoiding friction between the mounting part 2 and the kiln base 1, which would affect the rotational stability of the mounting part 2. Furthermore, the support wheels 23 roll in the guide groove, effectively improving the rotational stability and uniformity of the mounting part 2. The support wheels 23 are made of high-temperature resistant and thermal shock resistant materials, and the mounting plate 8 in the mounting part 2 is made of a material with good heat insulation properties, ensuring the service life of the support wheels 23 in high-temperature environments.

[0050] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
