Abstract
The invention provides an installation way of a mould used for producing flat-wide aluminum alloy section bars. The mould comprises a mould pad, a mould body and a ring which are arranged in sequence. Compared with an installation sequence of an existing tool mould used for producing the aluminum alloy section bars, the installation way disclosed by the invention solves a problem that the two sides of each of the aluminum alloy section bars are contacted with the inside of the mould pad to generate deformation when the mould pad is arranged in front of the wide spreading mould and the aluminum alloy section bars are extruded; meanwhile, the mould is changed to a third stress object from a second stress object, so that the deformation generated in the process of extruding an aluminum alloy cast ingot of the mould has a relatively high protective effect; the mould pad is equivalent to a guide mould of the wide spreading mould, and has the effect on adjusting the metal flow uniformity while the aluminum alloy section bars are extruded. Therefore, the installation way disclosed by the invention can enable the prepared flat-wide aluminum alloy section bars to have a relatively good forming property by resetting the installation sequence of the mould.
