Die special for lower bell jar

Abstract

The invention discloses a die special for a lower bell jar. The die comprises a male die, a female die and a blank holder. A male die arc-shaped part is arranged on the top of the male die, a female die arc-shaped part is arranged inside one end of the female die, the two outer sides of the female die arc-shaped part are outer inclined surfaces, and flanges are arranged between the two outer inclined surfaces and the female die arc-shaped part. A cavity is formed inside the blank holder, the radius of a small male die arc part ranges from 50 mm to 200 mm, and the radius of a small female die arc part is 0 mm-10 mm larger than the radius of the small male die arc part. The die comprises the male die, the female die and the blank holder, the male die arc-shaped part and the female die arc-shaped part are mutually embedded correspondingly, rolled steel can be punched into the lower bell jar, the radius of the small male die arc part and the radius of the small female die arc part play a key role in achieving the glaze pouring effect of the lower bell jar, the radius of the small male die arc part is arranged to be from 50 mm to 200 mm, and the good glazing effect can be acquired through a glaze pouring experiment.

Description

technical field [0001] The invention relates to a special mold for a glazer of ceramic processing equipment, in particular to a special mold for preparing the upper and lower bell jars of the glazer. Background technique [0002] The bell jar glazing device was first produced in Europe. In the 1980s, as China began to introduce a large number of building ceramic production lines, it entered the Chinese market and was widely used. It became the main glazing equipment for the production of glazed tiles. With the continuous development and improvement of ceramic technology, glazers have been widely used in the production process of glazed tiles such as interior wall tiles, glazed floor tiles, antique tiles, and fully polished glazed tiles, and have become the first choice for glazing wall and floor tiles. The bell jar type glazer generally includes an upper bell jar, a middle bell jar and a lower bell jar. The lower bell jar is generally made of steel, and the existing lower b...
