Description

TECHNICAL FIELD

[0001] The utility model relates to zirconia porcelain block sintering technical field, specifically a kind of high-temperature sintering device for zirconia porcelain block production. BACKGROUND

[0002] The main use of zirconia porcelain block is usually used for fixed denture repair, and the common size on the market is Φ98×14. The conventional production process of zirconia porcelain block at present is as follows: zirconia powder is added into a mold, and the powder is formed into a desired shape by hydraulic pressing, which can be referred to as pre-pressing. The product is then finally trimmed to the desired shape by isostatic pressing. Then, the product that can be sold is obtained through high-temperature sintering, mechanical processing, silk-screen printing and packaging.

[0003] High-temperature sintering is to place the pressed zirconia blank material in a high-temperature furnace for high-temperature sintering for a period of time. The zirconia product is a disc-shaped product, which is not suitable for vertical sintering. Currently, the zirconia porcelain block blank is usually sintered in a stacked and laid manner.

[0004] In the patent file with the publication number CN216049157U, a high-temperature sintering device for zirconia porcelain block production is disclosed, which comprises a sintering furnace. A rotating shaft is movably connected to the shaft center of the inner wall at the bottom of the sintering furnace through a bearing, and a positioning ring is welded on the outer side wall of the rotating shaft in an equidistant and upward-downward structure. The utility model column under the action of limiting disc and spring pushes the adapter between zirconia porcelain block and through the support, so that the zirconia porcelain block can be more stable when sintering in the inside of the placing groove. The uniform distribution of the adapter can effectively improve the sintering effect and efficiency of the bottom of the zirconia porcelain block. The servo motor drives the rotating shaft to rotate through the driving gear and the driven gear. The rotating shaft drives the first adapter disc and the second adapter disc to rotate and sinter through the positioning ring, so that the zirconia porcelain block can be sintered more uniformly and efficiently, thereby improving the sintering efficiency of the zirconia porcelain block.

[0005] In the above-mentioned prior art, although the sintering can be made more uniform, the placing groove is arranged inside the sintering furnace, and the zirconia porcelain block is taken out and placed in through the opening of the furnace door. The internal space of the sintering furnace is limited, which makes it inconvenient to take out and place the zirconia porcelain block. Therefore, the high-temperature sintering device for zirconia porcelain block production is proposed to optimize the above-mentioned prior art. UTILITY MODEL CONTENTS

A zigzag base 5 is fixedly connected between the two sliding grooves 4. A flat plate 6 is fixedly connected between the two sliding grooves 4 at the top. A rotating shaft 7 is rotatably installed between the flat plate 6 and the zigzag base 5. Multiple fixing rings 8 are fixedly connected at equal intervals on the rotating shaft 7.
