Abstract
The invention belongs to tire-mold technical fields, disclose a kind of tire-mold antifriction plate of roll mode.Including substrate, cylindrical roller, elongated slot, bolt hole, retainer, elongated slot is provided with inside the substrate, the cylindrical roller is connected on retainer, and the retainer limits cylindrical roller and is installed in substrate elongated slot, and the substrate is fastened on tire-mold by bolt hole.The present invention becomes rolling friction from original sliding friction, and coefficient of friction reduces, and keeps tire-mold die sinking and die closing process more smooth.
Description
Technical field
The invention belongs to field of tire more particularly to a kind of tire-mold antifriction plates of roll mode.
Background technique
The machine-shaping needs of tire are completed in tyre adjustable die.In tire-mold, upper cover and pedestal etc. are uniformly distributed
It is equipped with corresponding wearing piece, to guarantee tire-mold opening and closing flexibly, reduces the abrasion between part and the friction system between opposite grinding part
Number, design have tire-mold antifriction panel assembly.Mould parts realize mold die sinking and die closing by the radial motion in antifriction plate
Process.With being continuously increased for mould open/close process, abrasion can be generated between opposite grinding part, the result of abrasion makes tire-mold part
Between gap increase, so as to cause the generation on tire sealant side, influence the presentation quality of tire.Antifriction plate material is usually copper graphite
Alloy, tire-mold opposite grinding part is sliding friction at present, and coefficient of friction is larger.It is direct when antifriction plate surface wearing layer is ground off
The folding of mold is influenced, or even the parts stuck phenomenon such as arcuate seat, T-block occur, makes mold cisco unity malfunction, meeting when serious
Mold is caused to scrap.For current tire-mold service condition, this sliding friction mode coefficient of friction is larger, stress compared with
Greatly, it is easy to make antifriction plate wear-out failure, die sinking and die closing process is caused to have some setbacks.And antifriction plate is needed to be replaced frequently, lead to mould
The maintenance cost of tool increases.
It is sliding friction that tire-mold structure, which is between antifriction plate and opposite grinding part, at present, i.e. connects between two parts for plane
Touch sliding friction.Solve the meaning of above-mentioned technical problem: antifriction plate (the pedestal antifriction plate, upper cover of different location in tire-mold
Die closing antifriction plate, upper cover are opened antifriction plate, middle set antifriction plate, gib block) realizing the movement side in tire-mold moving process
To being different, the arrangement angle of cylindrical roller is set according to the direction of motion of the above-mentioned corresponding wearing piece of antifriction plate, realize with
The parallel motion of opposite grinding part.The motion mode is rolling friction, reduces coefficient of friction.
Summary of the invention
To solve the above problems, the present invention provides a kind of tire-mold antifriction plates of roll mode, when in use, rely on
The process of die sinking and die closing is realized in the rolling of cylindrical roller.This structure is by the friction mode between antifriction plate and opposite grinding part by sliding
Dynamic friction is changed to rolling friction, and coefficient of friction reduces, and stressed effect is improved, and tire-mold die sinking and die closing process are more
It is smooth, it 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 antifriction plate of roll mode, packet
Substrate, cylindrical roller, elongated slot, bolt hole, retainer are included, elongated slot is provided with inside the substrate, the cylindrical roller is connected to guarantor
It holds on frame, the retainer limits cylindrical roller and is installed in substrate elongated slot, and the substrate is fastened by bolt hole
On tire-mold.
Cylindrical roller (2) center line makes arcuate seat and circle according to the setting of arcuate seat quantity and Front line angulation
Column roller makees parallel motion, and when arcuate seat quantity is 8, angulation is 45 °；When arcuate seat quantity is 10, angulation is
36°；When arcuate seat quantity is 12, angulation is 36 °.
The central axis of cylindrical roller (2) center line and opposite grinding part, guarantees moving radially for arcuate seat.
It is clearance fit between the cylindrical roller (2) and retainer (5).
The cylindrical roller (2) is using whole stepped construction.
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: guaranteeing that the stress effect that substrate itself is carried is outer, inside be provided with
Elongated slot, cylindrical roller are connected on substrate by retainer, and substrate is fastened on tire-mold by bolt hole, antifriction when work
Plate and opposite grinding part are performed relative motion by the rolling of cylindrical roller on substrate, and rolling friction occurs, realize tire-mold die sinking and
Die closing process is the motion state of rolling form.The arrangement mode of cylindrical roller can make carried pts wt mean allocation,
Make to roll more smooth.Cylindrical roller limits itself using stepped construction, and when rolling prevents its sideslip.Same conventional wheel
Loose tool lamps structure compares, and copper-graphite alloy layer is eliminated on substrate, when the abrasion of antifriction plate, only needs to change worn-out circle
Column roller does not change substrate, saves cost.Meanwhile antifriction plate and the relative motion mode of opposite grinding part change, i.e., by original
Sliding friction becomes rolling friction, reduces coefficient of friction, and stressed effect is improved, and makes tire-mold die sinking and die closing process
It is more smooth.

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 antifriction plate of roll mode, including substrate 1, cylindrical roller 2, elongated slot
3, bolt hole 4, retainer 5.Guarantee substrate 1 itself carried stress effect under, inside be provided with elongated slot 3, cylindrical roller 2
On substrate 1 by the connection of retainer 5, substrate 1 is fastened on tire-mold by bolt hole 4.
In conjunction with shown in Fig. 1, Fig. 2, Fig. 3, when tire-mold works, antifriction plate and opposite grinding part are rolled by the cylinder on substrate 1
The rolling of son 2 performs relative motion, and rolling friction occurs, and realizes die sinking and die closing process is the motion state of rolling form.Cylinder
The arrangement mode of roller 2 can make carried pts wt mean allocation, make to roll more smooth.Cylindrical roller 2 uses ladder
Formula structure limits itself, and when rolling prevents its sideslip.
