Mould for tyres of vehicles for the segmented pneumatic tyres unpaved roads

摘要

"The mold of pneumatic tyres for roads segmented to vehicles road not paved.The present invention consists in a method and a device for equipping the upper and lower parts of molds of tyre of two pieces of an expandable opening.In order to provide clearance for the insertion of pneumatic tyres in particular raw, raw large type used in industrial vehicles or roads road not paved.The mold according to the present invention pneumatic tyre has a segmented mold in which a plurality of segments prepared by.Contributing to the conformation of the part of the tread of the tyre is being molded.They are able to move so as to include a component of radial movement which provides a larger diameter for each of the two parts of the mold during operation of charging the pneumatic CRu. Thus, the inner circumferential region of part of the top and part of the base is able to expand in diametral dimension when the mold of pneumatic two pieces is open.
