Forging die

Abstract

The invention provides a forging die. The die comprises an upper die base and a lower die base, and a movable cavity is formed in the upper surface of the lower die base. An opening is sealed by a lower die plate mounting plate fixedly connected with a top screw; the upper die base is movably connected with the lower die plate mounting plate through a guide rod; the upper die base can move up anddown along the guide rod; a lower die plate and an upper die plate which correspond to each other are fixedly mounted on the upper surface of the lower die plate mounting plate and the lower surface of the upper die base through fastening screws; a top plate is arranged in the movable cavity; a negative pressure self-cleaning mechanism is arranged in the lower die base; the negative-pressure self-cleaning mechanism is communicated with a die cavity of the lower die plate; when the die is closed, the mold is opened, a guide rod structure drives the top plate to move downwards; and when the topplate moves downwards, air in a negative pressure chamber of the self-cleaning mechanism can be pumped out to form a negative pressure environment, after die opening, an air valve is communicated, airin the die cavity of the lower die plate flows into the negative pressure chamber through a dust falling groove, residual metal dust in the die cavity is brought into the dust falling groove under the action of airflow to be collected and guided out, and good development prospects are achieved.

Description

technical field

[0001] The invention relates to the field of forging dies, in particular to a forging die. Background technique

[0002] A forging die is a tool that can shape a blank into a die forging. Forging dies are the key process equipment necessary for the production of die forgings. Through the extrusion of the die, the raw material is plastically deformed in the forging die under the action of external force, so as to obtain the required shape and size parts. It is a tool that needs to be used in every stroke of the equipment and plays a decisive role in the production of die forgings. role.

[0003] Forging molds often process semi-finished parts, and the parts themselves are easily stained with metal dust generated during the additional process. With the use of the mold, the metal dust is easy to accumulate in the cavity, and the inner wall of the cavity is hardened under the continuous extrusion of the mold. Adhesion in blocks will affect the shape of the for...
