Specific embodiment
In order to preferably explain the present invention, in order to understand, with reference to the accompanying drawing, by specific embodiment, to this hair
It is bright to be described in detail.
As shown in Figures 1 to 5, in the present embodiment, a kind of non-inflatable tyre inside evacuation formula mold core is provided,
In, mold core includes multiple fan-shaped mold core units 1, and multiple mould heart units 1 are spliced to form ring structure.
Mold core unit 1 includes the forming part 11 on the outside of it, and the outer surface of forming part 11 is provided with mold core groove 12.
Mold core is divided into multiple fan-shaped mold core units 1, to facilitate extraction mold core, in mold core knockout course, benefit
When agitating single flat back die core unit 1 with the elasticity of rubber material, mold core is easier to release, be combined when manufacturing tire
Getting up is exactly a circle.
Mold core groove 12 is along the direction arrangement of the upper surface of mold core unit 1 to lower surface and/or along 1 lateral surface of mold core unit
Be circumferentially arranged.
When mold core unit 1 is horizontally arranged, mold core groove 12 is arranged along the direction of the upper surface of mold core unit to lower surface
Refer to be that the both ends of mold core groove 12 are arranged through the upper and lower surfaces of mold core unit 1, in the present embodiment, with such
The mold core groove 12 of form setting is the first mold core groove 121, it is preferred that the first mold core groove 121 is with respect to the horizontal plane vertical
Setting, or it is inclined relative to horizontal setting.
First mold core groove 121 can be designed to arbitrary shape, after molding for the blade on forming tire as needed
The blade on the single groove both sides of tire can be arbitrary shape and thickness, so, the first mold core groove 121, which exports out, can be
Arbitrary shape.Round as rectangular, irregular shape, rectangular four corners are reinforced into triangle, arc etc..
Mold core groove 12 is circumferentially arranged along 1 lateral surface of mold core unit, specifically refers to be, when 1 level of mold core unit is put
When setting, mold core groove 12 is through to the other end from one end of mold core unit 1, and the mold core groove 12 of such form setting is the second mould
Core groove 122.
Second mold core groove 122 for the reinforcing rib on forming tire, reinforcing rib in order to fortified tyre use intensity and
It is different with size length can to do various shape for the comfort level effect of tire, the tire intensity according to required for using vehicle
Mold core groove 12.Second mold core groove 122 can be one or more compositions, and (be embodied on tire is exactly that reinforcing rib can be one
Item is a plurality of, or without reinforcing rib).Second mold core groove 122 can be set according to actual needs into different height, length and
Shape, part and the reinforcing rib that along direction blade extends of the tire after molding along spue line inner wall direction as a result, can be with
It is designed to different height and length and different shapes as needed.
Mold core unit 1 includes multiple templates being distributed up and down, and multiple template is successively bonded setting along the thickness direction of the mould heart.
Mold core unit 1 is divided into multiple template, more facilitates the demoulding of mold core.
According to the size of wheel, mold core can be designed to different size and thickness, and mold core is formed with mold muti-piece template
Closed space heating rubber material molds tire finished product.After this tire building is good, by tire body, groove, blade, add
Strengthening tendons, card slot (can be a card slot with tire assembly, be also possible to straight flange or various shape) composition.According to using vehicle institute
The intensity needed can design the space size and random shape variations of mold core groove, tire body decorative pattern, it is possible thereby to adjust
Shape, the size of groove on the inside of tire, shape, size, length and the thickness of blade, the shape of reinforcing rib, size length and
Thickness, i.e. mold core groove part can change according to the needs of product.If the shape of mold core open end can be rectangular, circle,
Irregular shape, rectangular four corners are reinforced into triangle, arc etc..
As a preferred embodiment, mold core unit 1 includes cope plate and lower template, and cope plate and lower template are bonded to each other,
A part of mold core groove 12 is located on cope plate, and another part is arranged in lower template.Such as it is arranged on mold core unit 1
There is a second mold core groove 122, a part of the second mold core groove 122 is arranged on cope plate, and another part is arranged under
In template, after cope plate and lower template are mutually butted, a complete second mold core groove is formed between the two.
Thickness when 1 through-thickness of mold core unit is divided into multiple template, that is, when there is multilayer core pulling, between multiple template
It may be the same or different, be also not excluded for the situation that mold core unit 1 is an entirety certainly.
Mold core groove 121 is located on single mold core unit 1 and/or between adjacent mold core unit 1.
It should be noted that in the present embodiment, the case where mold core groove 121 is set on mold core unit 1 is provided,
Certainly according to actual needs, mold core groove 121 can also be not provided on mold core unit 1.
The thickness as outside of forming part 11 is different from its inner thickness, it is preferred that the thickness as outside of forming part 11 is greatly in the inner
The thickness of side is also not excluded for the thickness as outside and its inner thickness unanimous circumstances of forming part 11 certainly.It is done using such mold
It is in that the inside large outlet is small or the inside is small after being made into finished product at tire, on the inside of tire, outlet is big, it might even be possible to by inside and go out
Mouth is made into equally big.
Mold core includes multiple equally distributed mould heart units 1.Mold core further includes fixing seat 2, is provided in fixing seat 2 multiple
Fixed column 21.Mold core unit 1 further includes fixed part 13 on its inside, is provided on fixed part 13 and matches with fixed column 21
