During operation, the dentures are usually placed in the middle of the sintering porcelain furnace for heating. However, for large quantities of dentures, if the overall stability is not achieved during loading and unloading, it is easy to cause displacement between the dentures, resulting in accumulation and affecting the uniformity during sintering. For this reason, a denture sintering porcelain furnace is proposed. Utility Model Content

Example

[0034] See also Figure 1 - Figure 6 A denture sintering porcelain furnace includes a sintering area 101 arranged on a porcelain furnace body 1, a denture sintering disk 2 with multiple placement slots 203 is arranged above the sintering area 101, and an upper fixing plate 3 with multiple openings 301 is arranged in the denture sintering disk 2 for stability.

[0035] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 The denture sintering porcelain furnace of the present application is mainly composed of a porcelain furnace body 1 and a sintering area 101 and other structures. A denture sintering disk 2 is set in the sintering area 101, wherein a plurality of placement grooves 203 are evenly opened inside the denture sintering disk 2 for placing the dentures. After the dentures are placed in the denture sintering disk 2, the upper fixed disk 3 is supported flatly on the upper part of the denture without contact, and the larger end of the denture, that is, the lower part, is placed in the placement groove 203, so that the denture is limited between the denture sintering disk 2 and the upper fixed disk 3. The opening 301 is used for the circulation of air inside and outside the porcelain furnace body 1 to prevent displacement, ensure the stability of loading and unloading, and prevent the dentures from piling up due to displacement, thereby affecting the uniformity during sintering.

[0036] It should also be noted that the size of the placement groove 203 is customized according to the actual placement size of the denture to ensure that one end of the denture can be placed stably; the opening 301 is set smaller than the placement groove 203, and the two are staggered so that the denture located between the denture sintering plate 2 and the upper fixed plate 3 can obtain internal and external air replacement to ensure the sintering effect; the structure processed in the sintering area 101 in the porcelain furnace body 1 is made of high-temperature resistant materials.

[0037] A support structure is also provided in the present application, and the support structure is mainly composed of a support base 5, a movable frame 501 and a movable plate 502. The support base 5, the movable frame 501 and the movable plate 502 are each provided with two groups, which cooperate with each other to support the upper fixed disk 3 on the denture sintering disk 2, wherein the support base 5 is symmetrically installed at the two ends of the bottom of the denture sintering disk 2, and the movable plate 502 is symmetrically installed at the two ends of the top of the upper fixed disk 3. The movable frame 501 and the support base 5 are designed as an integrated structure, so that the end of the movable plate 502 extending from the outside of the upper fixed disk 3 can be relatively movable inside the movable frame 501. When the movable plate 502 is inserted into the movable frame 501, the upper fixed disk 3 is supported inside the denture sintering disk 2 to ensure stability.

[0038] The present application also provides a latch 503, and both the movable plate 502 and the movable frame 501 are provided with a matching latch 503. When one end of the movable plate 502 is movably installed inside the movable frame 501, the upper fixed plate 3 is driven to move in the same direction by moving the movable plate 502 up and down, so that the upper fixed plate 3 is located at the corresponding position above the denture. When the holes at the movable frame 501 and the movable plate 502 are in an aligned state, the latch 503 is inserted into them to fix it. In this way, the height of the upper fixed plate 3 inside the denture sintering plate 2 is adjusted to improve applicability.

[0039] See also Figure 3 、 Figure 5 and Figure 6 A positioning structure is also provided in the present application. The positioning structure is mainly composed of an external positioning cylinder 201 and a support rod 202, wherein the external positioning cylinder 201 is installed in the middle of the bottom end of the denture sintering disk 2, and the support rod 202 is fixedly installed in the middle of the upper surface of the sintering area 101. When the denture sintering disk 2 is placed as a whole in the porcelain furnace body 1 and is located on the porcelain furnace body 1, the external positioning cylinder 201 is sleeved on the outside of the support rod 202, and the denture sintering disk 2 can be positioned as a whole in the sintering area 101. At the same time, the height set by the external positioning cylinder 201 can lift the denture sintering disk 2 for support.

[0040] The present application also provides a barrel mouth 204, which is fixedly installed at the bottom of the outer positioning barrel 201. The cross-section of the outer positioning barrel 201 toward the lower end is set in a conical state to facilitate the insertion of the barrel mouth 204 into the groove on the sintering zone 101. At the same time, the groove is located on the outer periphery of the support rod 202 to further position the connection between the outer positioning barrel 201 and the support rod 202.

[0041] The present application also provides a stable base 6, an anti-slip convex layer 601 and a sleeve tube 602. The anti-slip convex layer 601 is evenly glued to the bottom of the stable base 6. Its material is rubber. When the stable base 6 is added to the bottom of the porcelain furnace body 1 as a whole, the friction of the contact surface can be increased when the porcelain furnace body 1 is placed on a flat surface for use, while avoiding slipping and other phenomena; the sleeve tube 602 is fixedly installed at the four corners of the top of the stable base 6, and can be correspondingly sleeved on the four bases at the bottom of the porcelain furnace body 1. Therefore, the stable base 6 can be assembled as a whole and can be removed at any time to improve convenience during use.
