Description

Technical Field

[0001] The utility model belongs to the technical field of molds and relates to a low-cost hot-molding mold structure for aluminum alloy parts. Background Art

[0002] Aluminum alloy parts are generally formed by hot pressing of molds. During the forming process, the workpiece to be processed needs to be placed in a high-temperature furnace for heating. This step is called the hot mold process. The workpiece after hot mold treatment is more easily deformed by extrusion and has good ductility, and is not prone to breakage or damage during the stamping process. Existing aluminum alloy die-stamping molds generally use upper and lower molds. The lower mold is generally an integrated mold. Once the internal structure of the mold is worn during use, the entire lower mold needs to be replaced. Due to the integrated structure, it is also relatively difficult to clean the residual impurities produced after the molding, resulting in a high molding production cost. Therefore, it is urgent to design a low-cost aluminum alloy part hot molding mold structure that can overcome the above defects.

[0003] In order to overcome the shortcomings of the prior art, people have proposed various solutions through continuous exploration. For example, a Chinese patent discloses a titanium alloy hemispherical head hot compression molding die [application number: 202311190781.0], including a hemispherical lower die and a spherical upper die located above the hemispherical lower die, the spherical upper die is fixedly arranged at the bottom of the pressure rod of the press, and the spherical upper die is fixedly assembled at the bottom of the pressure rod, the bottom of the hemispherical lower die is also fixedly installed with a base for support, and the interior of the hemispherical lower die is fixedly installed with an energized vortex wire.
