Abstract
The present invention relates to the apparatus fields of production tire, specifically a kind of tire-mold can roll T-block structure, including T-block, cylindrical roller, elongated slot, bolt, lower plate, straight pin, the T-block shoulder is provided with elongated slot below two sides, the cylindrical roller is connected on lower plate by straight pin, and the lower plate is fastened by bolts to inside T-block elongated slot.The present invention becomes rolling friction from the sliding friction between original T-block and upper cover, reduces the coefficient of friction of T-block and upper cover, keeps die sinking and die closing process more smooth, and improve the stress of upper cover, while eliminating upper cover and opening slide plate part.
Description
Technical field
The present invention relates to the apparatus fields of production tire, and specifically a kind of tire-mold can roll T-block structure.
Background technique
Currently, most of mold of domestic production tire is loose mould of radial ply tire, and in tire-mold, T-block
Play the role of connecting upper cover and arcuate seat, upper cover and open the lower surface that slide plate is located at T-block shoulder two sides, by T-block with it is upper
The sliding friction that lid opens slide plate makes mold realize die sinking and die closing process.Upper cover open sliding material be usually copper-graphite alloy or
Tin bronze alloys, at high cost and area is small, is prone to wear, and when 1mm wearing layer is ground off when surface, will affect the folding of mold, very
To there is pattern block stuck phenomenon, scrap die wear.For current tire-mold service condition, this sliding friction side
Formula coefficient of friction is larger, and stress is larger, is easy that upper cover is made to open slide plate wear-out failure, die sinking and die closing process have some setbacks, therefore need
It often to replace upper cover and open slide plate, the maintenance cost of mold is caused to increase.
Summary of the invention
To solve the above problems, the present invention provides a kind of tire-molds can roll T-block structure, when in use, T-block
It is directly contacted with upper cover, by cylindrical roller in the rolling of upper cover, realizes the process of die sinking and die closing.This structure removal upper cover is opened
Slide plate, and the friction mode between T-block and upper cover is changed to rolling friction by sliding friction, coefficient of friction reduces, stress
Effect is improved, and die sinking and die closing are more smooth, ensure that the work quality of tire-mold.
To achieve the above object, the invention provides the following technical scheme: a kind of tire-mold can roll T-block structure, packet
T-block, cylindrical roller, elongated slot, bolt, lower plate, straight pin are included, elongated slot, the circle are provided with below T-block shoulder two sides
Column roller is connected on lower plate by straight pin, and the lower plate is fastened by bolts to inside elongated slot.
The cylindrical roller and the gap for being above stamped 1mm.
The cylindrical roller is made of high temperature resistant and anti abrasive nylon material.
The lower plate and elongated slot clearance fit.
After technical solutions according to the invention, bring it is following the utility model has the advantages that
Technical solution designed by the present invention is: the connection function for guaranteeing T-block and upper cover and arcuate seat and itself
The stress effect carried is outer, and the cutting elongated groove below T-block shoulder two sides, cylindrical roller is connected to lower plate by straight pin
On, cylindrical roller is directly contacted with upper cover when work, by rolling of the cylindrical roller on upper lid, realizes die sinking and die closing mistake
Journey.Compared with conventional wheel placenta structure, the relative motion mode of T-block and upper cover is changed, i.e., is rubbed by original sliding
Wiping becomes rolling friction, and eliminates upper cover and open slide plate, reduces coefficient of friction, and stress is improved so that die sinking and
Die closing process is more smooth, to guarantee the work quality of tire-mold.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description.
As shown in Figure 1, Figure 2, a kind of tire-mold slidably T-block structure, including T-block 1, cylindrical roller 2, elongated slot
3, bolt 4, lower plate 5, straight pin 6, elongated slot 3 is provided with below 1 shoulder two sides of T-block, and cylindrical roller 2 is connected by straight pin 6
On lower plate 5, lower plate 5 is fastened to inside elongated slot 3 by bolt 4.
In conjunction with shown in Fig. 1, Fig. 2 and Fig. 3, after tire-mold is kept completely separate with tyre surface, hot plate of vulcanizer drives upper cover 7 one
It rises and moves up, after being moved upwards up to certain altitude, under guiding role, arcuate seat 9 is rolled by cylinder under force
Rolling of the son 2 in upper cover 7 is internally tightened, and rolling friction occurs, and arcuate seat 9 stops movement after tightening, and cylindrical roller 2 is immediately
Stop rolling, tire-mold continues to move up, and provides space to change tire, die sinking process is completed.
Tire-mold first drops to designated position, then hot plate of vulcanizer remains stationary, under upper cover 7 continues in molding
It moves, under guiding role, realization radially expands arcuate seat 9.During arcuate seat 9 radially expands, cylindrical roller 2 is in upper cover 7
Rolling friction occurs for upper rolling.It is to roll to stop after cylindrical roller 2 rolls corresponding stroke when it is opened completely, under arcuate seat 9
Move until its bottom surface and tire-mold bottom connection touch, hot plate of vulcanizer slowly moves down, under force arcuate seat 9 it is radial to
In tighten, upper surface closes slide plate 8 with upper cover and rubs.Since upper cover 7 has pre-load amount, under the action of mold clamping force, sulphur
Change machine and upper cover 7 completely attach to, and clamping process is completed.
The foregoing is merely illustrative of the preferred embodiments of the present invention, it is noted that it is all the spirit and principles in the present invention it
Interior, any modification, equivalent replacement, improvement and so on should be included within the scope of the present invention.
