Abstract
The utility model discloses a kind of rubber, PU and EVA triple density soles, it is the lamination layer structure coupled with lower rubber layer one by top PU layers, the position corresponding to half sole of the PU layers, it is spacing have along PU layers by toe cap to the EVA matter for moving towards to extend heel before fill out the heart, it is described before fill out the heart and be enclosed in PU materials；This utility model additionally provides the footwear with above-mentioned sole.The sole of existing dual density construction is changed to triple density structure by this utility model, the heart is filled out before adding one layer of EVA matter in the middle of sole and upper bottom, the density of density ratio PU of EVA is little, and there is preferably elasticity, so that sole has the advantages that density is little, elastic big, with low cost, the functions such as the light of footwear, damping can be improved on the basis of reduces cost.This utility model is applied to various rubber, PU and EVA triple densities sole and corresponding footwear.
Description
Technical field
This utility model is related to shoe-making field, and the more particularly to improvement of rubber and PU dual-density soles specifically, is one
Plant rubber, PU and EVA triple densities sole and the corresponding footwear with triple density sole.
Background technology
Existing rubber and PU dual-density soles, using rubber and PU direct injection molding.Employ rubber and PU double densities
Degree sole footwear preparation process, including carry out successively with side with last carving followed by heating, heel it is cold formed, draw side, set side,
Gather around with, strike and pound arrangement, and viscous hook the operations such as the heart.
The footwear of the rubber and PU dual-density soles of above-mentioned technique productions, in its sole, the density of PU parts should not be too little,
Because too little can lose intensity；But if the too big weight that can increase sole, wears not light again.
The content of the invention
The technical problems to be solved in the utility model, is the drawbacks described above of the presence solved by prior art, there is provided a kind of
Rubber, PU and EVA triple density soles, to realize ensureing while PU layer intensity, make the elasticity of sole again and are able to into footwear weight
The purpose of guarantee；
Another purpose of the present utility model, is to provide a kind of footwear with triple density sole.
To solve above-mentioned technical problem, the technical scheme adopted by this utility model is：
A kind of rubber, PU and EVA triple density soles, are compound with what lower rubber layer one coupled by top PU layers
Rotating fields, in place of its difference with the prior art be：The position corresponding to half sole of the PU layers, it is spacing have along PU layers by
Toe cap fills out the heart to before the EVA matter for moving towards to extend between heel, it is described before fill out the heart and be enclosed in PU materials.
As restriction, it is described before fill out the profile of the downward projection of the heart, in the profile of rim of the mouth.
As another kind of restriction, it is described before fill out what is be separated by with multiple levels in the heart, the upper and lower surface of the heart is filled out before penetrating
Fill out heart material feeding hole, described filling out fills the PU materials for having and front filling out side in the heart, the PU materials of lower section combine together in heart material feeding hole.
Used as the third restriction, the position corresponding to heel of the PU layers is spacing to have along followed by move towards the heel for extending
The little palm, the little palm of the heel are enclosed in PU materials.Before fill out between the rear end of the heart and the front end of the little palm of heel before and after be separated by point
Cloth.
As further limiting：
The heel is little to be slapped as EVA matter；
The little profile for slapping downward projection of the heel, in the profile of rim of the mouth；
The little palm of the heel is separated by with multiple levels, penetrates the little palm material feeding hole of the little palm lower surface of heel, institute
State in little palm material feeding hole and fill the PU materials for there are the PU materials with the little palm side of heel, lower section to combine together.
This utility model additionally provides a kind of footwear preparation method with triple density sole, and its structure has two kinds of situations：
1. the triple density sole for aforesaid with front filling out the heart（Without the little palm of heel）Rubber, PU and EVA triple densities
Sole；
2. the triple density sole is aforesaid not only with front filling out the heart but also the rubber with the little palm of heel, PU and EVA triple density footwear
Bottom.
As a result of above-mentioned technical scheme, compared with prior art, acquired technological progress exists this utility model
In：
(1) sole of existing dual density construction is changed to triple density structure by this utility model, i.e., in sole and upper bottom
The heart is filled out before one layer of EVA matter of middle addition, the density of density ratio PU of EVA is little, and there is preferably elasticity, so that sole has
Density is little, it is elastic big, with low cost the advantages of, the functions such as the light of footwear, damping can be improved on the basis of reduces cost.
Equally, the little palm of EVA materials, can also cause sole to have above-mentioned effect；
(2) size that the heart and the little palm of heel are filled out before is that the two is total determining according to the space size and rim of the mouth profile of PU layers
The profile of body is less than rim of the mouth profile, and their thickness to be ensured the space of the laminar flow up and down of PU, that is, reserve the sky that PU runs material
Between passage；
(3) because EVA materials it is incompatible with PU materials, fill out the setting of heart material feeding hole and little palm material feeding hole, can allow PU expect from
In through in order to front fill out the heart and heel it is little the palm the position of sole fixation, prevent the two from shifting.
This utility model is applied to various rubber, PU and EVA triple densities sole and corresponding footwear.
This utility model is described in further detail with specific embodiment below in conjunction with Figure of description.
