Problems solved by technology

[0002] Molds are various molds and tools used in industrial production for blow molding, injection molding, extrusion or forging molding, smelting and other methods to obtain the required products. With the explosive growth of the photovoltaic market, the demand for crucibles is also increasing. At the same time, the size of the crucible is getting larger and larger, and the manufacture of the crucible requires the use of molds, but the structure of the traditional crucible mold is complex, not resistant to high temperature, and has poor strength and is easy to damage

Abstract

The invention discloses a preparation method of a quartz crucible mold. The preparation method specifically comprises the following steps: (1) grinding raw material components respectively and mixingand stirring according to the ratio; (2) injecting a mixture into a mold and adding filler; (3) drying in a vacuum drying box, wherein the vacuum degree is 0.08 to 0.09MPa, the drying temperature is 50 to 55 DEG C and the time is 2 to 4h; (4) putting the mixture into a heating furnace and heating by sections, wherein specific temperature is as follows: 200 to 260 DEG C, 350 to 420 DEG C and 550 to620 DEG C; (5) spraying and coating the filler; (6) sintering in a sintering furnace, wherein in a whole sintering flow technology, the time is 24 to 26h and the temperature is 1100 to 1220 DEG C. The quartz crucible mold disclosed by the invention has high strength, good wear resistance and high temperature resistance and the service life is prolonged.
