Description

Integral meridian loose die

Technical field

The present invention relates to a kind of sulfidization molding machinery parts, specifically a kind of Integral meridian loose die of off-the-road tyre.

Background technology

China's automobile production and marketing in 2009 completes respectively 1379.10 ten thousand and 1364.48 ten thousand, increases respectively on year-on-year basis 48% and 46%.To the end of the year 2009, China's automobile pollution has reached 7619.31 ten thousand, compared with last year, increases by 1152.10 ten thousand, increases by 17.81%, and China's automobile tire market capacity is larger as can be seen here.Tire enterprise expands the scale of production one after another both at home and abroad, certainly will strengthen the amount of purchase to tire-mold.57 " Integral meridian loose die contrasts the balance quality of traditional segmented mold prodigiosin raising tire, can reduce the material cost that mould is manufactured, and can expand the scope of application of vulcanizer, can reduce the equipment investment of tyre vulcanization.Improve designing and manufacturing level and the production capacity of the high-grade radial-ply tyre mould of China, dwindle the gap compared with international most advanced level, progressively meet the demand of high-performance tire to mould, reduce the import of high-grade meridian loose die.Along with the enforcement of the policies such as " automobile industry adjustment and revitalize planning ", " vehicle-purchase tax reduces by half ", " automobile go to the countryside policy ", " old motor vehicle liquidation renewal Chinese Financial Subsidy Policies ", China Automobile Industry has welcome blowout developing period.This Project Product has larger market capacity and vast potential for future development.

It is split type in existing technology, having slide block and the pattern block of traditional activating mold structure, mold integral takes up room larger, cause the die cavity of sulfidization molding less, the maximum sulfuration of the vulcanizer specification of same size is less, has so just limited the scope that vulcanizer uses.In development process, technical staff is guaranteeing to dwindle under the enough strength conditions of slide block and pattern block the volume of slide block and pattern block as far as possible.

Summary of the invention

The invention provides and a kind of Integral meridian loose die miniaturization can be expanded to the scope of application on vulcanizer, reduce the investment of equipment, improve the activating mold of the utilization rate of equipment.

Technical solution problem of the present invention provides following scheme:

A kind of Integral meridian loose die, comprise base, lower side panel, epipleural, it is characterized in that: on described base, be installed with lower side panel, the right-hand member of described lower side panel is supported with lower steel ring, described lower steel ring is fixedly connected with lower chuck, the top of described lower side panel is provided with upper cover, the lower surface of described upper cover is installed with epipleural, the upper steel ring of right-hand member fixed installation of described epipleural, on described upper steel ring, be extruded with platen, described platen is fixedly mounted on chuck, the left end of described epipleural and the lower side panel disjunctor pattern block that is slidably matched, described disjunctor pattern block upper end is fixed with pinboard, described pinboard is inserted in upper cover, the lower end of described disjunctor pattern block is placed on base, the outer wall of described disjunctor pattern block is skewed and is fixed with guide pad, described guide pad is slidably mounted on middle die sleeve.

The base of the left end of described lower side panel is provided with wearing plate.

The invention has the advantages that:

Realize the activating mold miniaturization of more difficult realization, expanded the vulcanizer scope of application.

Realize that existing equipment is more difficult to be guaranteed activating mold folding flexibly and met the smooth tread flaking of radial and axial stroke.

Operation principle of the present invention:

1., when matched moulds, under the effect of vulcanizer mold clamping force, mold clamping force by middle die sleeve inner each independently tapered plane apply pressure to the inclined-plane of disjunctor pattern block, and form the power that disjunctor pattern block moves to center position, radially slide at the guiding surface of middle die sleeve and the gib block guiding sliding block being contained on disjunctor pattern block, thereby promote disjunctor pattern block around upper, lower fetal pleuron closes up, now before work, tested upper cover connects mutually with upper sidewall plate and vulcanizer upper mounted plate, under driving, the power cylinder of vulcanizer ensures and lower fetal pleuron coaxial line, avoid causing producing overlap after tyre vulcanization because of upper lower fetal pleuron disalignment.

2., when the demoulding, vulcanizer upper mounted plate promotes, in drive, die sleeve up moves; Disjunctor pattern block is along with the lifting of middle die sleeve is moved to external diameter direction along spigot surface is past; Middle die sleeve is promoted to certain altitude, and disjunctor pattern block starts to depart from base, and continues to move up; When being promoted to, disjunctor pattern block enough highly stops continuing motion, central authority push rod jack-up, and take the gas in capsule away, capsule is shunk; Central authority push rod backhaul rotation moves downward, and capsule is folded up; Mechanical arm of vulcanizer takes out the tire having vulcanized.
