CN1330475C - Mould for making ball with rubber leather and artificial leather - Google Patents

Abstract

The present invention relates to a mould for making balls with rubber leather and artificial leather, which is a hollow spherical mould which can be divided into two hemispheres, wherein the surface of the inner side of one hemisphere is provided with smooth zones and grain zones at internals, the number of the smooth zones is the same as that of the grain zones, and the depth of each grain zone is larger than that of each smooth zone; the surface of the inner side of the other hemisphere is provided with grain zones and smooth zones, the positions of the grain zones and the smooth zones are opposite to the positions of the smooth zones and the grain zones of the hemisphere, and the depth of each grain zone is also larger than that of each smooth zone. By utilizing the mould, the surface of the formed middle tire forms grain surfaces at intervals; since the smooth surfaces between every two grain surfaces are deep, artificial leather can be stuck, the whole surface of the sphere can not be rugged, and the surface of the sphere has the texture of the artificial leather and the hand feeling of rubber leather.

Description

Make the mould of tool rubber skin and leatheret spheroid

Technical field

The present invention relates to a kind of mould of making tool rubber skin and leatheret spheroid, refer to that especially a kind of surface that can make has the mould of the spheroid of rubber skin and leatheret simultaneously.

Background technology

Spheroid is (as basketball, vollyballs etc. are various ball) how to be manufactured with the spheroid inner tube of a tyre earlier in manufacturing process, be the line body that inner tube of a tyre outside bundle is used around reinforced structure, after treating that the winding of line body finishes, again it is put in the middle tire mould, around between the spheroid of cable body, pour into vulcanized rubber with tire in forming in mould and bundle, charging connector (or being weighed into ball) is set on the tire in formed again, thereafter the grinding on tire surface in carrying out again, cleaning, erosion is to increase adhesive force, be pasted with eight leatherets in middle tire surface again, or utilize the hot pressing gimmick make in the tire surface be formed with nutty structure and become the surface texture of rubber skin.

Please referring to shown in Fig. 4 and 5, the middle tire mould of tire has the hollow sphere mould 30 that is separable into two halves spheroid 31,32 in existing the making, the inboard of each hemisphere 31,32 of this spheroid mould 30 is shiny surface 33, when spheroid mould 30 ccontaining bundles during, behind the perfusion vulcanized rubber, just can form the surface and slightly be tire in the smooth spheroid around the spheroid (not shown) of cable body.

But above-mentioned spheroid mould 30 only can be formed with tire in the spheroid of smooth surface, and produced spheroid need can be to finish leatheret or rubber ball body via follow-up several procedure of processings, this kind spheroid all has its shortcoming to exist on whole texture and practicality, though its reason is the leatheret spheroid and has preferable texture, but its smooth surface, do not have enough frictional force, when ball game is carried out, because not enough frictional force will have influence on user's object for appreciation player sense, in addition, though the surface of rubber ball body has enough frictional force, but its surface is because of having grain structure, therefore texture is not good, visually can't give a kind of high-quality impression of people.

If the spherome surface structure can have the characteristic of leatheret and rubber skin simultaneously, believe just and can solve foregoing problems, but the middle tire mould of tire in the above-mentioned making is because its hemisphere 31,32 inboards are shiny surface 33, therefore the middle tire of made can't reach the requirement that leatheret and rubber skin are set simultaneously, its reason is that leatheret is to utilize the attaching gimmick to be arranged on middle tire surface, and the rubber skin is directly to utilize the hot pressing gimmick to be formed with grain structure on middle tire surface, attach leatheret and the hot pressing grain structure will make that spheroid integral body is uneven at the middle tire part surface of a smooth surface, therefore the mould utmost point of tire is waited to improve in existing the making, with the demand of the spheroid that meets above-mentioned making tool leatheret and rubber skin surface.

Summary of the invention

Main purpose of the present invention is to overcome the deficiencies in the prior art and defective, and a kind of mould of making tool rubber skin and leatheret spheroid is provided.

In order to reach the foregoing invention purpose, the present invention takes following technological means to be reached, and mould wherein of the present invention is separable into the hollow sphere mould of two halves spheroid, it is characterized in that:

Wherein a hemisphere inner surface is arranged at intervals with the smooth areas and the granulomere of equal number, and the degree of depth of granulomere is greater than the degree of depth of smooth areas;

Second half spheroid inner surface is arranged at intervals with granulomere and the smooth areas that position opposite is set with aforementioned hemispheroidal smooth areas and granulomere, and the degree of depth of this granulomere is equally greater than the degree of depth of smooth areas.

By above-mentioned mould, the tire surface just is formed with particle surface at interval in formed, and the smooth surface between particle surface is because the degree of depth is darker, so can attach leatheret, make the spheroid integral surface not have rough phenomenon and take place, allow spherome surface have the texture of leatheret and the feel of rubber skin simultaneously.

The specific embodiment

Please referring to shown in Fig. 1 to 3, the mould that the present invention makes tool rubber skin and leatheret spheroid is the hollow sphere mould 10 that is separable into two halves spheroid 11,12.

Wherein a hemisphere 11 inner surfaces are arranged at intervals with the smooth areas 13 and the granulomere 14 of equal number, and the degree of depth of granulomere 14 is greater than the degree of depth of smooth areas 13;

Second half spheroid 12 inner surfaces are arranged at intervals with granulomere 14 and the smooth areas 13 that smooth areas 13 and granulomere 14 with aforementioned hemisphere 11 are provided with position opposite, and the degree of depth of this granulomere 14 is equally greater than the degree of depth of smooth areas 13.

In addition, smooth areas 13 and granulomere 14 quantity set on aforementioned each hemisphere 11,12 can be two, can also need increase and decrease according to the spheroid of the work of putting.

When the present invention uses in making spheroid tire, be that the spheroid of bundle around cable body is seated in the spheroid mould 10 equally, between the spheroid of cable body, pour into vulcanized rubber in spheroid mould 10 and bundle again, because the hemisphere 11 of spheroid mould 10,12 inboard is formed with granulomere 14 and smooth areas 13 respectively at interval, and because the degree of depth of granulomere 14 is greater than the degree of depth of smooth areas 13, therefore the tire surface can be formed with the surface texture of tool granulomere at interval in the spheroid of producing, and the smooth areas degree of depth between each granulomere can be greater than the granulomere, therefore as long as on the darker smooth areas of the degree of depth, attach leatheret, just can avoid leatheret outstanding by spherome surface, cause rough problem to take place, and the spherome surface of made just can have the texture of leatheret and the feel of rubber skin simultaneously.

In addition, the hemisphere 11,12 of this mould is inboard owing to have granulomere 14, and therefore middle tire does not need to form grain structure via any follow-up hot pressing means again, so can save the making step and the cost of spheroid.
