The invention provides a rapid design method of a tyre mould, which comprises the following steps of: 1) simplifying the expressed mould
design pattern, classifying the shape related characteristics of the tyre mould, and drawing and establishing a CAD (computer-aided design) pattern
library of the typical structure of various types of tyres; 2) compiling a special tyre designing and manufacturing specification, attaching tyre typical structure legends corresponding to the tyre typical
structure pattern library and the pattern of the simplified drawing work order, and classifying and
numbering the typical structure legends; and 3) correspondingly selecting a legend number from the typical structure specification according to the product shape, calling the CAD pattern from the typical
structure pattern library and filling the CAD pattern into the simplified drawing work order according to the number, and finally filling an
order number, a fixture pattern number and other simple information into the work order to finish the design. As the tyre typical structures in the invention are strictly classified, the classes nearly include all tyre structure types and the compiling idea is novel, the tyre mould is convenient and quick to use by designers, the
design speed is increased by 6-10 times than that before, and the manual labor and
material resources are saved. The invention can greatly shorten the production preparation period, and provides
solid technical storage for the development of new products.
