Problems solved by technology
In order to facilitate demoulding, currently commonly used isostatic pressing molds for ceramic nozzles are mostly segmented and connected with each other by slots. Although it is easy to disengage, there is a problem that the joints are easy to crack, which greatly reduces the product quality Yield of

Abstract
The invention provides an inner core of an isostatic pressing die for a ceramic nozzle with a single nozzle. The inner core comprises a long conical rod, a conical table and a bolt for connecting the conical rod and the conical table. Apart from a bolt hole communicated in the middle and connected with the conical rod on the conical table, the conical table is further provided with an un-communicated auxiliary hole with a certain depth to facilitate the screwing and unscrewing of the bolt. According to the inner core, a plurality of parts of a set of pressing die for the ceramic nozzle are firmly combined through the bolt, and the problem of blank cracking at a prior joint position caused by loose combining is solved. Simultaneously, as a bolt connection unit which is convenient to dismount is used, on one hand, the die is separated from a blank, stress damages during demoulding are reduced, and the product performance is improved; and one the other hand, the labor intensity is decreased, and the production efficiency is improved.
Description
technical field [0001] The invention relates to an isostatic pressing method for preparing a mold inner core for a single nozzle ceramic nozzle, which belongs to the field of forming and manufacturing inorganic non-metallic materials. Background technique [0002] Ceramic nozzles have important applications in the fields of flue gas desulfurization, denitrification and dust removal of large coal-fired boilers, papermaking, textiles, pharmaceuticals, metallurgy and other fields, and are new environmental protection products vigorously promoted by the country. High-quality ceramic nozzles should have the characteristics of high strength, high temperature resistance, corrosion resistance, and long service life, which puts high demands on the molding methods and molding tools of ceramic nozzles. [0003] At present, the commonly used molding method of ceramic nozzles is mainly grouting molding. The grouting molding process is complicated, the preparation cycle is long, and there...
