Abstract
The invention discloses a method for manufacturing hollow solid tire, comprising the following steps that: a plurality of modules are combined into a core; the core is fixed in a tire mould; the mould is folded; foaming liquids are injected to a pouring hole to enable the foaming liquids filled in a space between the inner wall of the mould and the core and solidified; the tire and the core are taken out of the mould and then the mould is dismounted to be taken out of the modules one by one, thereby forming a hollow solid tire. In the method, the core is easily dismounted and combined with the foaming material to form a hollow space in pouring and shaping the solid tire, and then the core are dismounted and then taken out one by one. The resulting hollow solid tire has the advantages of steady quality, good buffer and comfortable application.
Description
Technical field
The present invention relates to a kind of preparation method of tire, be meant a kind of comfortableness preparation method of hollow solid tire preferably especially.
Background technology
Initial tire all uses air tyre, and this air tyre is to use rubber to make the circular of hollow, is nested with then on the wheel hub of wheel, in use, charges into air in air tyre, can play good cushioning effect, is therefore used widely.Yet, this air tyre is when running into thrusts such as stone, be easy to tire is pricked quick-fried, wheel can't be moved, at some special occasions, as the wheelchair of disabled person's use, this situation is a danger close, therefore, load-bearing solid tyre is preferably arisen at the historic moment, and solid tyre generally uses rubber or foaming material to make, even on the road of Uneven road, situation such as also can not blow out, use safer, yet, because the deflection of solid tyre itself is less, when running into thrusts such as stone in the driving process, solid tyre directly passes to wheel hub with active force, causes comfortableness relatively poor.
In order to improve the comfort of solid tyre in the driving process, a kind of hollow solid tire has appearred, it is a fixation balloon in mould, utilizing the rotating disk that is connected with mould to drive entire die then rotates at a high speed, inject foaming material liquid by plug hole to die cavity simultaneously, the centrifugal force that is produced when rotating by mould, make the foaming material evenly fill whole die cavity, air bag is combined closely with the foaming material, thereby make air bag on the solid tyre of moulding, form a space, can cushion the active force that comes from the outside to a certain extent, improve the comfort of solid tyre.
Yet, in manufacturing process, because the uncertainty of the form of air bag own, and centrifugal force that air bag self produces in rotary course and foaming material are to the extruding of air bag, cause the air bag after the moulding and can't be in preposition really, but depart to some extent, so in the process of moving, the inwall of hollow solid tire is stressed and asymmetric, thereby influences the quality of product.
In view of above-mentioned analysis, the inventor studies improvement at the deficiency that present hollow solid tire exists in manufacturing process, and this case produces thus.
Summary of the invention
Main purpose of the present invention is to provide a kind of preparation method of hollow solid tire, the hollow solid tire steady quality that it is made, and good buffer effect, comfort is preferable.
In order to reach above-mentioned purpose, solution of the present invention is:
A kind of preparation method of hollow solid tire comprises the steps: a plurality of modules are combined core rod, and this core rod is fixed in the tire forming mold; Closed die injects foaming material liquid from plug hole, and also solidify in the space that foaming material liquid is full of between mould inner wall and the core rod; Then tire and core rod are taken out in mould, mould is disassembled and taken out module one by one, thereby form hollow solid tire.
Above-mentioned core rod comprises that being positioned at inner ring is fixed in the fixed part of mould and is positioned at the joint portion that the outer ring is incorporated into tire.
After adopting such scheme, the present invention changes tradition and uses air bag to form the mode of hollow space, and uses core rod moulding hollow space on solid tyre of hard, has following improvement:
(1), thereby, guaranteed the quality of finished product preferably in the tire inner wall stable molding because core rod can be because of centrifugal force be out of shape in casting process;
(2) after tire completes, conveniently core rod is disassembled, be convenient to from tire, take out, can not influence the quality and the form of tire;
(3) space of moulding can provide deformation space preferably on the tire, increases the deflection of solid tyre, helps to cushion external influence power, improves comfort.

Fig. 2 is the combination schematic diagram of core rod among the present invention;
Fig. 3 is the decomposing schematic representation of core rod among the present invention;
Fig. 4 is the decomposition elevation of core rod among the present invention.
The specific embodiment
Below in conjunction with drawings and the specific embodiments making flow process of the present invention is elaborated.
With reference to shown in Figure 1, the invention provides a kind of preparation method of hollow solid tire, comprise the steps:
(1) makes tire forming mold 1 and core rod 2, described mould 1 comprises the mold 11 and the bed die 12 that can fasten mutually, the center of mold 11 offers the plug hole 13 of perforation, and the center of bed die 12 is provided with core insert 121, and forms a containing cavity between the sidewall of core insert 121 and bed die 12; Core rod 2 is circular, and referring to figs. 2 to shown in Figure 4, it comprises fixed part 21 that is positioned at inner ring and the joint portion 22 that is positioned at the outer ring, and in the present embodiment, fixed part 21 and joint portion 22 are combined by 6 modules respectively, and use screw 23 to be locked respectively; Core rod 2 is positioned in the bed die 12 of mould 1, and fixed part 21 is fixed on the core insert 121;
(2) tire forming mold 1 that closes, and by plug hole 13 pouring foaming material liquid in mould 1, high speed rotating mould 1 makes foaming material liquid be full of the inwall of mould 1 and the space between the core rod 2 simultaneously, after the material of waiting to foam solidifies, combine closely in the joint portion 22 of foaming material and core rod 2;
(3) open mould 1, the tire after the moulding is taken out from mould 1 with core rod 2;
(4) take off screw 23, mould 2 disassembled, and with each module by taking out in the tire, have the hollow solid tire of an annular space thereby form inwall.
The hollow solid tire that adopts preceding method to make, utilize the strong character of die hard 2 self, form an annular space at tire inner wall in advance, because mould 2 quality are hard, when rotating at a high speed, can not produce distortion with mould 1 yet, thereby the annular space form of moulding is even, in the driving process to external world active force be able to even buffering, improve comfort; In addition, core rod 2 is to be assembled by a plurality of modules, and easy disassembly the foaming material combines curing with core rod 2 after, only needs core rod 2 decomposition can be taken out then one by one, and is simple to operate, and can not influence the form of core rod 2, can not have any impact to its use.
Above embodiment only for explanation technological thought of the present invention, can not limit protection scope of the present invention with this, every technological thought that proposes according to the present invention, and any change of being done on the technical scheme basis all falls within the protection domain of the present invention.
