Pressurization apparatus for preventing faulty formation pattern of tire

Abstract

The present invention relates to a pressure device for preventing the formation of defective tire pattern. Specifically, the pressure device comprises: a pushing unit which presses on an upper side ofa green tire to secure the same, can be separated at a middle portion thereof, and is formed at a lower side of a top plate while being in close contact therewith to be raised separately through a raising member from the top plate; a top plate which is formed on an upper surface of the pushing unit, has a pressing unit fixed thereto, and has the raising member fixed to an upper side thereof; a pressing unit which is joined to the top plate outwardly and downwardly, has an inner periphery formed diagonally so that the pressing unit applies a pressure inwardly by lowering the top plate, and hasan assembly unit (21) formed at a lower part thereof; a pattern unit which is formed in contact with the inner surface of the pressing unit to be raised through a slide, and is formed in multiple pieces such that the pattern unit, when raised, presses the outer periphery of a green tire to form a pattern thereon; and a supporting unit which is in contact with a lower side of the green tire to support the same, has a fixture formed outwardly and upwardly so as to correspond to the assembly unit formed at the lower part of the pressing unit, has an insertion groove in which a lower part of thepattern unit is inserted, and is secured to an upper part of a bottom plate.

Description

technical field [0001] The present invention relates to a pressurizing device for preventing the formation of bad tire treads, and relates to a pressurizing device for preventing the formation of bad tire treads by simplifying the assembly and maintenance by simplifying the structure of the pressing part and the supporting part, because Since the combination of the pressurizing part is meshed with the fixed body of the support part, the pressurizing part is not opened, and the pattern part is uniformly pressurized to prevent formation of defective tire patterns. Background technique [0002] Typically, a tire curing vessel receives a green tire and manufactures a finished tire by applying pressure and temperature to form protrusions or logos, etc., on the tread and sides of the tire. [0003] Such a conventional tire container includes: upper and lower side molds for molding the sides of the tire; tread molds arranged between the side molds for molding the tread portion of t...

Problems solved by technology

[0009] However, the existing patent still has the following problem. That is, if the upper end of the outer ring formed on the outside of the movable mold is worn due to the continuous lifting of the movable mold, normal pressure cannot be transmitted to the movable mold. Green tires form the tread
