Description
Technical field
The present invention relates to automobile tire mould technical field, be specifically related to tire-mold side plate wrongly written or mispronounced character body processing technology.
Background technology
The making of tire be unable to do without mould, and its specialized, commercialized degree and production concentration degree are the highest, mould structure from
Simple to complexity, mold materials is from cast iron to cast steel, cast aluminium and alloy cast steel, and mould processing technology is also from the most manual, electric
Spark is worked into applique processing.Along with the fast development of auto industry, tire enterprise to the precision of mould, quality, the life-span and
The requirement at date of delivery is more and more higher, and the needs forcing many Mold Making enterprises to be development self, in the precision, quality of mould
Make an issue of, to ensure that the tire that client's tire enterprise is produced is attractive in appearance, degree of accuracy is high, durable in use.But traditional huge work
Journey tire-mold processing mode is more single, mostly uses manual texturing and spark machined, and the course of processing is considerably complicated, tired
Difficult.And manual texturing are the most coarse, degree of accuracy is not high enough.
General tire has decorative pattern, i.e. on tire tread various longitudinally, laterally, the groove of oblique composition；But some are senior
White font pattern or trade mark is there is also on sport car tire.Tyre tread is not only the factor that whether beautiful its outward appearance is, and more closes
Be tied to whether can to give full play to tire traction, brake, turn, the performance such as draining and noise.When producing tire, on tire
Decorative pattern, white font pattern or trade mark be by the side plate steel disc molding of tire-mold.Make to improve the performance of tyre tread
With and wrongly written or mispronounced character body pattern or trade mark attractive in appearance, many tire producers require the side plate steel disc labyrinth to be had of tire-mold
Or stereochemical structure, requiring white font pattern or trade mark precision machining simultaneously, precision is high, and this just brings to the processing of tire-mold
Certain difficulty.
Current processing method typically uses electric machining mode to carry out the white font pattern of side plate or trade mark processing, but due in vain
Font is the big word of 3D, and the degree of depth on side board die is relatively deep, and usual electric machining mode easily occurs that lateral plates is hindered in erosion, and repeats to add
Man-hour, appearance cannot be accurately positioned, and affects machining accuracy, and size is the most overproof, increases difficulty of processing and process time.Therefore, this
The processing technique of kind tire-mold is in actual production process, and using effect is unsatisfactory, the most time-consuming, adds work
Measure and labor intensity, and, extremely waste processes raw material, and manufactures the burden brought on cost, practicality to enterprise
Poor.
Summary of the invention
It is an object of the invention to solve defect of the prior art, it is provided that tire-mold side plate wrongly written or mispronounced character body processing technology.
