Abstract
The fine flushing which is widely applied in the automotive and aerial industries is a new machining method .Whose principle was presented in this paper .The brake adjustment toothed rack mold of an automobile was designed with some refinement and originality that offered an ease of use and maintenance and a decrease in cost with the same precision . This paper also elaborated the entire design process including structure design and process design .
This instruction booklet through to the automobile brake adjustment toothed rack craft correct analysis, after has consulted the massive correlation data, has designed set of precise ramming molds. This article started from the craft analysis to the entire design process to carry on the exhaustive introduction, narrated the mold to take shape the components design and the processing technological process, the important components craft parameter choice and the computation, The selection of the process parameter and the press as well as some relative calculations ---such as the pressure center, was also performed. In this design has carried on the certain improvement and the innovation to the mold structure, causes it to be easier to operate and the service, in does not affect the work piece quality under the premise, reduced the production cost. Is advantageous to fine flushes the mold the popularization and the development.

Key Words: The automobile brake adjustment toothed rack；The essence flushes；Mold design
