Abstract
The present invention relates to a kind of vulcanizations of tire bead to prevent side die case, including die sleeve ontology, die sleeve ontology is spliced by two semicircular first die sleeves and the second die sleeve, it is set as groove-like on the inside of first die sleeve and the second die sleeve, first die sleeve includes first connecting portion, the upper and lower ends of first connecting portion are respectively arranged with the first top and first below, angle between bottom and upper segment is 75~80 °, second die sleeve includes second connecting portion, the upper and lower ends of second connecting portion are respectively arranged with the second top and second below, second top and second it is following between angle be 75~80 °.The configuration of the present invention is simple, ingenious in design, redundant rubber stock enters the phenomenon that causing bead edge in the circle of steel zero and capsule gap when can prevent tire bead from vulcanizing, and improves the qualification rate of product in sulfidation, convenient disassembly.
Description
Technical field
The present invention relates to a kind of vulcanizations of tire bead to prevent side die case, belongs to tire preparing technical field.
Background technology
With the development of China's tire technology of preparing, high-capacity tyre develops towards meridian, tubeless, flattening direction,
The Chinese all-steel load-bearing radial tire sales volume linear ascendant trend in market at home.However all-steel load-bearing radial tire is in life
Often go out finished product tire during production and show bead edge phenomenon, certain loss is brought to enterprise.
Invention content
The purpose of the present invention is to solve all-steel load-bearing radial tires in the prior art in sulfidation, and sizing material squeezes
Enter to the circle of steel zero with the gap of capsule, form bead edge problem, provides a kind of tire simple in structure, compact to design
Circle vulcanization is prevented side die case.
The present invention adopts the following technical scheme that：A kind of vulcanization of tire bead prevents side die case, including die sleeve ontology,
The die sleeve ontology is spliced by two semicircular first die sleeves and the second die sleeve, first die sleeve and the second die sleeve
Inside is set as groove-like, and first die sleeve includes first connecting portion, and the upper and lower ends of the first connecting portion are respectively set
Have the first top and first following, first top and first it is following between angle be 75~80 °, first connecting portion and the
One top, the first following surround form groove-like, and second die sleeve includes second connecting portion, above and below the second connecting portion
Both ends are respectively arranged with the second top and second following, second top and second it is following between angle be 75~80 °, institute
It states second connecting portion and the second top, the second following surround forms groove-like.
Further, the height of the first connecting portion and second connecting portion is 0.2~0.3cm.
Further, the radius of first die sleeve and the second die sleeve is 28.3~28.5cm.
The configuration of the present invention is simple, it is ingenious in design, when can prevent tire bead from vulcanizing redundant rubber stock enter steel zero circle with
The phenomenon that causing bead edge in capsule gap, improves the qualification rate of product in sulfidation, and convenient disassembly is easy to use.
Description of the drawings
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is the cross-sectional view of the present invention.
Reference numeral：First die sleeve 1, first connecting portion 2, the first top 3, the first top 4, the connection of the second die sleeve 5, second
Portion 6, the second top 7, second following 8.
Specific implementation mode
Below in conjunction with attached drawing, the invention will be further described.
As Figure 1-Figure 2, a kind of tire bead vulcanization is prevented side die case, including die sleeve ontology, die sleeve ontology
It is spliced by two 1 and second die sleeves 5 of semicircular first die sleeve, the inside of the first die sleeve 1 and the second die sleeve 5 is set as recessed
Channel-shaped, the first die sleeve 1 include first connecting portion 2, and the upper and lower ends of first connecting portion 2 are respectively arranged with the first top 3 and first
Following 4, the angle between the first top 3 and first following 4 is 75~80 °, and first connecting portion 2 and the first top 3, first are following
4 encirclements form groove-like, and the second die sleeve 5 includes second connecting portion 6, and the upper and lower ends of second connecting portion 6 are respectively arranged with second
Top 7 and second following 8, the angle between the second top 7 and second following 8 is 75~80 °, in second connecting portion 6 and second
Side 7, second following 8, which surround, forms groove-like, and the height of first connecting portion 2 and second connecting portion 6 is 0.2~0.3cm, the first mould
The radius of set 1 and the second die sleeve 5 is 28.3~28.5cm.
Application method：Tire bead vulcanization is prevented that side is placed on die case on the circle of steel zero when vulcanizer fills tire, mould
It covers and enters vulcanizer below ontology for the contact site of steel zero circle and capsule, dress fetus, the tyre bead portion of fetus is just in die sleeve sheet
In vivo, sizing material flowing is fixed by die sleeve ontology when vulcanization, will not be run steel zero and be enclosed in the gap contacted with capsule, effectively prevent
Bead edge phenomenon removes the first die sleeve and the second die sleeve after use from the circle of steel zero respectively.
