Abstract
The utility model provides a segmented mold for tires, belonging to the technical field of molds and solving the technical problems that pattern blocks of the existing segmented molds for tires can not be automatically opened reliably, and the like. The segmented mold for tires comprises an upper side plate, a lower side plate, a plurality of pattern blocks and a compression spring arranged between each pattern block and the lower side plate, wherein each pattern block is hinged on the lower side plate; one end of the compression spring is fixedly arranged at the lower end of each pattern block and the other end thereof is fixed on the lower side plate; and cooling troughs are arranged in the pattern blocks. The segmented mold for tires has the advantages that the pattern blocks can be reliably opened; and the segmented mold for tires has a good cooling effect.
Description
Technical field
The utility model belongs to technical field of mold, relates to a kind of tyre adjustable die.
Background technology
In sulfidation, outside condition makes between rubber in gum base ingredients and vulcanizing agent or rubber and rubber chemical reaction occurs, be cross-linked into the large molecule of space network by linear rubber macromolecule, greatly improved the properties of rubber by this reaction, made rubber obtain to satisfy physical and mechanical properties and other performances that product uses needs.The essence of sulfuration is crosslinked, and namely linear rubber molecule is converted into the netted configuration process in space.
a kind of tyre adjustable die is disclosed in patent (CN101125450A), comprise epipleural, lower side panel, some pattern blocks and middle die sleeve, the end of pattern block has hinge, this invention has been saved in existing tire vulcanizing segmented mold for the incline direction of pattern block guiding and the guiders such as T-slot of horizontal direction, manufacturing process of the present invention is simplified greatly, reduced production cost, but, be hinged on pattern block on lower side panel due to need to be along hinge through when die sinking and the Guan Mo, what utilize in above-mentioned patent is that inclined-plane on epipleural and pattern block reclines and realizes the upset of pattern block, pattern block can not well be opened when epipleural is opened automatically, thereby the phenomenon that pattern block can not normally be opened may appear.
Summary of the invention
The purpose of this utility model is the problems referred to above that exist for existing technology, and a kind of tyre adjustable die is provided, and technical problem to be solved in the utility model is in the middle of pattern block and lower side panel, a Compress Spring to be set, and pattern block can be opened automatically.
The purpose of this utility model can realize by following technical proposal: a kind of tyre adjustable die, tyre adjustable die comprises epipleural, lower side panel and some pattern blocks, it is characterized in that, described every pattern block all is hinged on described lower side panel, this activating mold also comprises a Compress Spring that is arranged between pattern block and lower side panel, one end of described Compress Spring is fixedly installed on the lower end of pattern block, the other end of described Compress Spring is fixed on lower side panel, is provided with cooling bath in described pattern block.
Operation principle of the present utility model is: when epipleural is closed, utilize epipleural with the inclined-plane that coordinates between pattern block, pattern block to be closed up, when epipleural is opened, the Compress Spring that is arranged between lower side panel and pattern block can push pattern block, pattern block is opened automatically, and in sulfidation, it is higher that pattern block encloses the interior temperature of the cavity that forms, for making pattern block can have cooling effect preferably, be provided with cooling bath in pattern block.
In above-mentioned a kind of tyre adjustable die, offer the opening that communicates with described cooling bath on described pattern block sidewall.In tire vulcanization process, be used for cooling liquid and enter in cooling bath from opening part, increase the contact area between pattern block and cooling liquid, to strengthen cooling effect.
In above-mentioned a kind of tyre adjustable die, be provided with a hinge between the lower end of described pattern block and lower side panel.Pattern block can rotate on lower side panel along hinge, the dismounting of mold before and after being convenient to vulcanize.
In above-mentioned a kind of tyre adjustable die, the lower end of described pattern block also is provided with a projection, and described projection can be resisted against on described lower side panel.Projection is to the spacing use of pattern block, and pattern block turns to certain angle, and when all pattern blocks can just in time form a complete annulus, projection was resisted against on lower side panel, and pattern block can not be rotated again.
In above-mentioned a kind of tyre adjustable die, this mould also comprises a guide pillar, and described epipleural and lower side panel all are slidably connected on described guide pillar.
Compared with prior art, the utility model is provided with a Compress Spring between pattern block and lower side panel, and this Compress Spring can when die sinking, open pattern block automatically.
