Die for casting saggar

Abstract

The invention discloses a die for casting a saggar. The die comprises a lower die outer frame, the middle of the lower die outer frame is provided with a lower die core, an upper die core is arranged above the lower die core in a matched mode, and the lower die core is of a floating die core structure and is composed of a lower die fixing die core and a lower die floating die core. A die core inner cavity is formed in the top of the lower die fixing die core, a through hole is formed in the bottom of the die core inner cavity, the lower die floating die core is arranged in the die core inner cavity, and a center ejecting cylinder is arranged at the bottom of the lower die floating die core. The center ejecting cylinder penetrates through the through hole in the lower die fixing die core and extends to the position below a worktable top of a pressing machine, and four wall plates are arranged between the inner wall of the lower die outer frame and the outer wall of the lower die core respectively. The four wall plates are connected and fixed at the four corners through inserts, and a filling block is embedded in the upper die core. The outer side of the filling block is provided with a cooling water channel, and an exhaust pipeline longitudinally penetrates the center of the upper die core. The die is good in exhausting and cooling effect and capable of facilitating discharging and solving the problems that the pressed saggar is large in number of air vents and uneven in thickness.

Description

technical field [0001] The invention relates to a mold for die-casting saggers. Background technique [0002] Sagger is a common kiln furniture. When the manufacturing industry was not popular, it was made of clay. After the development of modern manufacturing, refractory materials were gradually used to replace traditional clay, and the manufacturing process gradually evolved from The industrial production method of press die-casting refractory material molding often encounters the problem of uneven refractory material blanking when using press die-casting. Generally, operators usually manually blank the refractory material when blanking the refractory material. The depth of the lower mold is relatively deep, and when the refractory material is put in at one time, it is easy to cause uneven distribution, resulting in uneven thickness of the pressed sagger. [0003] In addition, when using a press for die-casting, it is often encountered that the mold is not ventilated smoo...
