Spark is worked into applique processing.With the fast development of auto industry, tire enterprise to the precision of mould, quality, the life-span and
The requirement more and more higher at delivery date, the need for forcing many Mold Making enterprises to develop itself, in the precision, quality in mould
Make an issue of, to ensure that the tire that client's tire enterprise is produced is attractive in appearance, accuracy is high, durable in use.But traditional huge work
Journey tire-mold processing mode is relatively simple, and mostly using manual texturing and electrical discharge machining, process is considerably complicated, tired
It is difficult.And craft texturing are more coarse, accuracy is not high enough.
General tire have on decorative pattern, i.e. tire tread it is various longitudinally, laterally, the groove of oblique composition；But some are senior
Also there is white font pattern or trade mark on sport car tire.Tyre tread is not only the whether beautiful factor of its outward appearance, and more closes
Whether be tied to can give full play to the performances such as traction, braking, turning, draining and the noise of tire.When producing tire, on tire
Decorative pattern, white font pattern or trade mark be to be molded by the side plate steel disc of tire-mold.In order to which the performance for improving tyre tread is made
With and wrongly written or mispronounced character body pattern or trade mark it is attractive in appearance, many tire producers require that the side plate steel disc of tire-molds will have labyrinth
Or stereochemical structure, while white font pattern or trade mark precision machining are required, and high precision, this just brings to the processing of tire-mold
Certain difficulty.
Current processing method typically carries out the white font pattern of side plate or trade mark processing using electric machining mode, but due to white
Font is the big words of 3D, and the depth on side board die is deeper, and usual electric machining mode erosion easily occurs and hinders lateral plates, and repeats to add
Man-hour appearance can not be accurately positioned, and influence machining accuracy, and size is often overproof, increase difficulty of processing and process time.Therefore, this
The processing technology of tire-mold is planted in actual production process, using effect is unsatisfactory, not only time-consuming, adds work
Measure and labor intensity, processed raw material moreover, extremely wasting, to the burden brought in cost manufactured of enterprise, practicality
It is poor.
