Abstract

The invention relates to a pressing die for refractory bricks, belongs to the field of pressing dies and solves the problem that annular convex ribs of the refractory bricks cannot be directly formed through extruding. The pressing die comprises a punch and a die holder component, a forming groove matched with the punch is formed in the die holder component, the die holder component comprises a forming die, resetting springs, bolts and a fixing seat, and the forming die is connected with the fixing seat through the bolts and can axially move along the bolts; the forming groove is formed in the forming die, a limiting hole is formed in the bottom wall of the forming groove, a punching block matched with the limiting hole is arranged on the fixing seat and comprises a punching portion, a sealing portion and a connecting portion sequentially from top to bottom, and space between a first limiting block and a second limiting block is smaller than or equal to height of the punching portion.

Description

technical field [0001] The invention relates to a pressing mold for refractory bricks, which belongs to the field of pressing molds. Background technique [0002] Add the refractory powder into the forming groove of the punch seat, and then, the punch quickly moves downward to hit the forming groove, so that the refractory powder in the forming groove is compacted to form a refractory brick. The diameter of the punch is usually smaller than the diameter of the forming groove. In order to facilitate the excess refractory powder to be squeezed into the gap between the punch and the forming groove, the annular rib of the refractory brick is formed. The height of the annular rib is About 30mm or so. However, the height of the annular ribs of refractory bricks should reach 50mm-90mm at present, and the annular ribs of this height cannot be directly extruded by existing punches. Contents of the invention [0003] The problem to be solved by the present invention is to provide ...
