Description

The quick detachable automobile tire two-half die of pattern block

Technical field

The utility model relates to tire-mold technical field, especially relates to the quick detachable automobile tire two-half die of a kind of pattern block.

Background technology

What require tyre performance along with industrial vehicle and other various purpose-built vehicle improves constantly, and traditional pneumatic tire can not meet instructions for use in some occasion.The appearance of solid rubber tyre, can meet the particular/special requirement of specific condition to tire in some aspects.Mould for all kinds of tire of sulfidization molding is divided into two classes: 1, activating mold, by pattern ring, and die sleeve, upper and lower side plate composition.Activating mold cyclotomy conical surface guiding activating mold and tapered plane guiding activating mold.2, mold halves, is totally made up of upper die and lower die, annex.Patrix is made up of upper pattern block and Upper Die-sleeve, counterdie is made up of lower pattern block and lower die-sleeve, pattern block is nested in die sleeve, but existing two-half die is nested in mould due to pattern block, in mold use process, the assembling of pattern block and Upper Die-sleeve or lower die-sleeve is more fastening, dismantle more difficult when changing pattern block, need carry out knocking dismounting by hard tools such as hammers, but the material due to decorative pattern is aluminium alloy, material is softer, knocking of hard tool can cause pattern block to be out of shape, especially the die cavity place of pattern block, if distortion, affects the outer shape of the tire processed, cause the appearance of substandard products tire, reduce efficiency, add labour cost.

Utility model content

The technical problems to be solved in the utility model is: pattern block die cavity place can be caused to overcome in prior art to be out of shape with the more fastening pattern block of hard tool dismounting, affect the outer shape of the tire processed, cause the appearance of substandard products tire, reduce efficiency, add the problem of labour cost, provide a kind of pattern block quick detachable automobile tire two-half die.

The utility model solves the technical scheme that its technical problem adopts: the quick detachable automobile tire two-half die of a kind of pattern block, comprise upper die and lower die, described patrix comprises Upper Die-sleeve and upper pattern block, described upper pattern block is nested in Upper Die-sleeve, described counterdie comprises lower die-sleeve and lower pattern block, described lower pattern block is nested in lower die-sleeve, be positioned on the Upper Die-sleeve inner surface located bottom pattern block and be evenly distributed in some upper through holes, described upper through hole comprises the first through hole and the first screwed hole, described first through hole is near described upper pattern block, the central axis of described first through hole and the central axes of described first screwed hole, the radius of described first through hole is greater than the outer radius of described first screwed hole, module has been slidably fitted with in described first through hole, described module is installed with threaded post, described threaded post screw thread is arranged in the first screwed hole, be positioned on the lower die-sleeve inner surface located bottom lower pattern block and be evenly distributed in some lower through-holes, described lower through-hole comprises the second through hole and the second screwed hole, described second through hole is near described lower pattern block, the central axis of described second through hole and the central axes of described second screwed hole, the radius of described second through hole is greater than the outer radius of described second screwed hole, be slidably installed in described second through hole module, and described threaded post screw thread is arranged in the second screwed hole.

Further, the central axis of described first through hole is all vertical with the die joint of two-half die with the central axis of described second through hole, described module is vertical with the power in threaded post to be acted on upper pattern block and lower pattern block, power is without decomposing phenomenon, less power can be used upper pattern block and lower pattern block to be unloaded, save labour, also reduce the damage of module to upper pattern block and lower pattern block simultaneously.

Further, in order to make the contact area of module and upper pattern block or a module and lower pattern block maximum, reduce the damage of module to upper pattern block and lower pattern block, the shape of cross section of described module is identical with the cross sectional shape of described first through hole, in order to simplify processing and installation step, the shape of cross section of described second through hole is identical with the shape of cross section of described module, described first through hole is all identical with the size and shape of described second through hole, with the use of a module of same model, the processing of module and the installation of mould can be facilitated.

When mould is installed, first will play module and threaded post is arranged in through hole and lower through-hole respectively, upper pattern block will be nested in Upper Die-sleeve, then lower pattern block will be nested in lower die-sleeve; When needs dismounting pattern block, only need rotate the threaded post that upper and lower mould puts respectively, make threaded post promote module, a module just promotes upper and lower pattern block and departs from upper and lower die sleeve.

The beneficial effects of the utility model are: the utility model structure is simple, easy to operate, more conveniently while not damaging pattern block dismantle pattern block quickly, decrease the occurrence number of substandard products tire, save working time, improve labor productivity ratio.
