Manufacturing process for die-casting saggars with refractory materials

Abstract

The invention discloses a manufacturing process for die-casting saggars with refractory materials. A method that a mold is die-cast by a press is adopted. The mold comprises an upper mold core, wherein the upper mold core is provided with a cooling water channel and an exhaust pipeline, a lower mold core matched with the upper mold core is arranged below, and the lower mold core adopts a floating structure. During mold opening, the lower mold core rises to the highest position, and the refractory materials are evenly placed onto the floating mold core of a lower mold; a switch of the press is pressed to press the upper mold core downwards, when the upper mold core is pressed downwards to the floating mold core of the lower mold, the floating mold core of the lower mold drops along with the upper mold core, the bottom surface of the floating mold core of the lower mold is stopped from dropping when being pressed downwards to a working table surface of the press, the upper mold core drops continuously at the moment, the refractory materials distributed on the lower mold core are compacted, after compaction, the upper mold core rises, and the floating mold core of the lower mold returns to the initial position. The manufacturing process is convenient in blanking and can solve problems that a lot of air holes exist in the pressed saggars and the saggars are uneven in thickness.

Description

technical field [0001] The invention relates to a manufacturing process of die-casting saggers using refractory materials. 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 encou...
