Battery shell male mould and hot-pressing process

Abstract

The invention provides a battery shell male mould and a hot-pressing process. The battery shell male mould comprises a core mould and a plurality of metal linings which are matched with the core mould, wherein any metal lining is provided with a bottom wall and side walls which extend out in the same direction from the peripheral edges of the bottom wall, the bottom wall and the side walls are enclosed to form a cavity which communicates with the outer part; the edges of the side walls are further connected with lining flanges which extend outwards; the core mould is provided with a lug boss which is matched with the cavity in shape; and the lug boss is positioned on a bottom plate; and the part, bulged and extended to the peripheral edge of the lug boss, of the bottom plate defines a coremould flange of the core mould. According to the battery shell male mould provided by the invention, an existing male mould is designed into a structure with the core mould and the plurality of the metal linings, so that heat transfer efficiency, in a hot-pressing process of the male mould, is improved, weight of the male mould is relieved, transfer is convenient, continuous and automatic production for a prepreg mould-pressing battery shell is realized, and production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a positive mold of a battery case and a hot pressing process. Background technique [0002] Reducing energy consumption, energy saving and environmental protection are the themes of social development today. With the continuous progress of human social civilization, industrial modernization is more and more closely integrated with us, the modern economy is developing day by day, and the demand for energy is further increasing. Moreover, fossil energy has certain harm to the atmospheric environment and affects people's health. The global energy and environmental systems are facing enormous challenges. As a major contributor to oil consumption and carbon dioxide emissions, automobiles need revolutionary changes. Changing the traditional use of energy for automobiles, developing new energy vehicles, and getting rid of dependence on oil has become a national strategy. At t...
