Design method of tire mould

Abstract

The invention discloses a design method of a tire mould, belonging to the technical field of the tire mould. According to the design method, pitch units with M pitches are available, and the plurality of pitch units with the same pitches are arranged; the pitch units with N pitches are selected for permutation and combination, so that the tire mould is formed, wherein N is less than or equal to M; all the pitch units can be freely interchanged at the circumference position; when mold closing is carried out on all the selected pitch units, a complete tread pattern is formed; the tire mould can be combined by selecting the pitch units with different pitches, and tread patterns with different pitch arrangements can be obtained by changing the permutation and combination of the pitch units in the several selected pitch units, so that multiple tires can be obtained by one mould, the optimal tread pattern pitch arrangement is obtained, and the cost for developing and testing a new tire can be lowered; and therefore, the design method of the tire mould is widely applied to the development of the new tire.

Description

technical field [0001] The invention relates to the technical field of tire molds, in particular to a tire mold design method. Background technique [0002] The tire pattern is not only the decisive factor for the beautiful appearance of the tire, but also related to whether the tire can give full play to the traction, braking, turning, drainage and noise performance of the tire. It is mainly composed of grooves and ribs. With the tire industry With the development of the development, the tire patterns produced by various tire manufacturers are different, so there are many kinds of tire patterns. When designing tires, the pitch arrangement of the tire pattern is random, and can be arranged and combined into many types of patterns with the change of the pitch. The pitch is the smallest fan-shaped unit that can be repeatedly arranged corresponding to the ribs or grooves. In the mold, the fan-shaped unit corresponding to a single pitch in the tire pattern is called a pitch uni...

Problems solved by technology

To achieve this goal, there will be great shortcomings or deficiencies in theoretical design alone. Therefore, in addition to the necessary CAD-assisted design, it is necessary to vulcanize tires with different pitch arrangements for experimental tests of various indicators, and this is Multiple specifications (types) of mold investment are required, and after the test is completed, except for the selected plan, the rest have no application value. This single modeling method has caused high cost investment and huge waste
