Abstract

The invention relates to a compacting die for a refractory brick and belongs to the field of compacting dies. The compacting die solves the problem that annular protruding ribs of the refractory brick are not high enough. The compacting die comprises a punch and a die holder component, wherein a forming groove matched with the punch is formed in the die holder component, the die holder component comprises a forming die, reset springs, bolts and a fixed base, the forming die is connected with the fixed base through the bolts and can move in the axial direction along the bolts, a material taking part capable of moving in the axial direction along the punch is arranged on the punch, positioning holes are formed in the material taking part, positioning protrusions can be inserted into the positioning holes so that the material taking part can be fastened to the bottom wall of the forming groove, a punch block matched with a limiting hole is arranged on the fixed base and is provided with a punch portion, and the distance between a first limiting block and a second limiting block is smaller than or equal to the height of the punch 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.
