Abstract

The invention relates to a forging technology and a device, in particular to aluminum alloy liquid forging molding technology and a module. In light of the technical problems that the prior art adopts complex module and process not suitable for aluminum alloy liquid forging, etc., the invention provides the forging module with simple structure and easy operation as well as the aluminum alloy liquid forging molding technology with reasonable process. The main technical proposal of the invention is as follows: a lower left module and a lower right module are arranged and fixed on a lower template in parallel, and a cylinder bottom punch gets through the lower template and is arranged between the lower left module and the lower right module; liquid aluminum alloy is injected into a cavity through a pouring port between the lower left module and the lower right module; an upper module is arranged on the lower left module and the lower right module and a pillar is also arranged and fixed; when in forging, the cylinder bottom punch conducts upward squeezing movement on liquid aluminum alloy; after meeting forging requirement, pressure can be maintained for 30 to 50 minutes.

Description

technical field [0001] The invention relates to a forging technology and equipment thereof, in particular to an aluminum alloy liquid forging forming technology and a mold thereof. Background technique [0002] In recent years, with the rapid development of the automobile industry, more urgent requirements have been put forward for reducing the weight of products to reduce energy consumption and pollution. Lightweight green environmental protection materials will be the first choice for people. [0003] Lightweight, precise, and efficient will be important development directions for future manufacturing technologies. Taking automobile manufacturing as an example, a 10% reduction in vehicle weight can increase combustion efficiency by 7% and reduce pollution by 10%. In order to achieve this goal, the weight of the whole vehicle is required to be reduced by 40% to 50%, of which the weight of the body and frame is required to be reduced by 50%, and the power and transmission sy...
