Problems solved by technology

[0003] The forging dies of the prior art have the following deficiencies: (1) The upper and lower dies are subjected to mechanical external forces during the film laminating process, which easily produces dislocations and affects the accuracy of forging; (2) when stamping, the die cavity The air in the air will form an air bag, and the air bag will rebound under high pressure, so that the material cannot fill the product cavity

Abstract

The invention discloses a breathable forging die, which relates to the technical field of forging. The mold includes an upper mold and a lower mold that cooperate with each other; the bottom of the upper mold and the top of the lower mold are provided with mold cavities; the mold cavities of the upper mold and the lower mold include resistance bridges, product cavities, flash grooves, jaws ;The resistance bridge is in the form of a ring structure, the inner side of which forms a product cavity, and the outer side is surrounded by flash grooves; on the resistance bridge of the lower mold, there are ventilating pinholes penetrating from top to bottom; the mold also includes a positioning structure, which is used to Limit the relative position between upper die and lower die. The invention has the advantages of precise positioning during forging, and the billet filling the cavity of the product.

Description

technical field [0001] The invention relates to the technical field of forging, in particular to a breathable forging die. Background technique [0002] Auto parts such as hub brackets, three-arm flanges, etc. are usually forged by high-temperature hydraulic methods. By placing the blank after heating treatment in the intermediate frequency furnace in the product cavity of the lower mold, the hydraulic cylinder drives the upper mold to press down for forging, and then lifts the upper mold, and the product is formed in the cavity of the lower mold and taken out manually Product, complete the forging of the product. [0003] The forging dies of the prior art have the following deficiencies: (1) The upper and lower dies are subjected to mechanical external forces during the film laminating process, which easily produces dislocations and affects the accuracy of forging; (2) when stamping, the die cavity The air in the cavity will form an air bag, and the air bag will rebound u...
