Background technology
Tire-mold is processed one of most important former as tire product, and its quality and performance also direct relation the quality of tire.Along with the development of digital control processing and manufacturing technology, the structure of tire-mold and manufacturing process also need to constantly bring forth new ideas.
Current tire-mold is divided into two kinds: activating mold and mold halves.Wherein mold halves mainly comprises upper mold section and female die two large divisions, can become flat when making tyre vulcanization, reaches sulfuration requirement, all need on upper mold section and female die, inflate hole, edge air-casing, and such structure makes to vulcanize the tire glue post.Activating mold is used after some cycles, due to releasing agent and thermal oxidation, make model surface produce dirt and sizing material obstruction, cause part steam vent obstructed, once steam vent has stopped up, easily cause air between tire and mould not discharge smoothly and affect sizing material and flow, produce the defects such as tire shoulder fillet, flower piece fillet, sidewall starved and scar, cause the tire of sulfuration become substandard products or scrap.And in mold halves, use after a period of time, need to carry out gel resin, cleaning to mould, dredging steam vent, not only time-consuming, effort, improves tire production cost, also can make reduce the service life of mould.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of good exhaust effect and Combined-type sheet-type two halves tire-mold simple in structure.
For solving the problems of the technologies described above, the technical solution of the utility model is: Combined-type sheet-type two halves tire-mold, comprise upper mold section and female die, between described upper mold section and female die, be provided with die cavity, described upper mold section comprises upper mold section matrix, and the upper decorative pattern sheet of die cavity described in some loops is installed on described upper mold section matrix;
Described female die comprises female die matrix, and the lower decorative pattern sheet of die cavity described in some loops is installed on described female die matrix.
As a kind of preferred technical scheme, between adjacent described upper decorative pattern sheet, be provided with resistance glue exhaust seam.
As a kind of preferred technical scheme, between adjacent described lower decorative pattern sheet, be provided with resistance glue exhaust seam.
As a kind of preferred technical scheme, between described upper decorative pattern sheet and described upper mold section matrix, be provided with resistance glue exhaust seam; Between described lower decorative pattern sheet and described female die matrix, be provided with resistance glue exhaust seam.
As a kind of preferred technical scheme, described resistance glue exhaust seam width is 0.005mm～0.035mm.
As a kind of preferred technical scheme, described upper decorative pattern sheet is two, three, four or five, and described lower decorative pattern sheet is two, three, four or five.
As a kind of preferred technical scheme, described upper mold section matrix is provided with the upper decorative pattern portion of mating with the decorative pattern of described upper decorative pattern sheet, and described female die matrix is provided with the lower decorative pattern portion of mating with the decorative pattern of described lower decorative pattern sheet.
Owing to having adopted technique scheme, Combined-type sheet-type two halves tire-mold, comprises upper mold section and female die, between described upper mold section and female die, is provided with die cavity, described upper mold section comprises upper mold section matrix, and the upper decorative pattern sheet of die cavity described in some loops is installed on described upper mold section matrix; Described female die comprises female die matrix, and the lower decorative pattern sheet of die cavity described in some loops is installed on described female die matrix; Two halves tire-mold described in the utility model can be divided into many parts processing, compares and only has upper and lower two-part two-half die, and the processing used time is short, can Supply period shortened; The parts of the tire-mold that specification is identical can also be general mutually, when part parts damages, can be several the device combination that damages of covers become a set of equipment to use, saved use cost.
In tire building process, need to through resistance glue exhaust seam, discharge from the gas of discharging in die cavity, two halves tire-mold is without inflating the processing such as hole, edge air-casing, and the production cost of mould reduces; Resistance glue exhaust seam can provide good venting quality and mold flow properties, effectively reduces tyre vulcanization defect, improves tire yield rate; It is simple, convenient that mould cleans, and without dredging steam vent, maintaining number of times is few, can effectively extend the service life of mould.
