Abstract
The utility model discloses an air-discharge mechanism for a die. The utility model is characterized in that the air-discharge mechanism comprises a breathable steel die insert and an air passage communicated with the breathable steel die insert, wherein the breathable steel die insert is fixed in a fixed die or/ and a movable die on the forming side of the die. The end face of the breathable steel die insert is flush with the surface of a die cavity. The air passage runs through the fixed die or/ and the movable die to be communicated with the atmosphere for discharging air. The air-discharge mechanism has a simple structure and can discharge the air in the die cavity, thereby improving the quality of products.
