Cold-work die facilitating heat dissipation

Abstract

The invention discloses a cold-work die facilitating heat dissipation. The cold-work die comprises a rack, a working table, a male die and a female die, wherein the rack is fixed on the working table; the male die is fixed on a lifting device above the rack; the female die is of a T-shaped sleeve structure; a heat dissipation lantern ring is connected outside the female die in a sleeving manner; a locating plate and a guide circular ring are arranged on the upper surface of the heat dissipation lantern ring in sequence from bottom to top; the guide circular ring, the locating plate, the female die and the heat dissipation lantern ring are connected to and fixed on the working table through connection studs in a penetrating manner; and a fillet is formed at a through opening in the center of the upper surface of the female die. According to the cold-work die facilitating heat dissipation, the heat dissipation lantern ring is connected to the outer side of the female die in the sleeving manner, and a heat dissipation channel is formed in the mutual contact surface, so that the impact strength of the female die can be improved, the heat dissipation treatment of the die can be accelerated, the service life of the die is prolonged, and the maintenance and repair cost is reduced.

Description

technical field [0001] The invention relates to a mold, in particular to a cold working mold which is easy to dissipate heat, and belongs to the field of mechanical processing. Background technique [0002] Cold working dies are commonly used in mechanical cold working such as stamping and blanking. Existing blanking and stamping dies for mass production will increase the frequency of mold clamping due to the need to increase output during use, which will cause the temperature of the die surface to increase, the frequency of impact vibrations will increase, and the damage to the die will be great. [0003] In order to solve the above problems, we propose a cold working die that is easy to dissipate heat. Contents of the invention [0004] The technical problem to be solved in the present invention is to overcome the defects of the prior art and provide a cold-working mold that is easy to dissipate heat. In order to solve the above technical problems, the present invention...
