Abstract

The utility model relates to a one-step forming sole made of dual-density rubber, belongs to daily life items, and discloses a keel. The keel and the sole are formed through one-step injection molding; the keel comprises a main keel and more than one keel chip; the keel chips are parallel to one another, arranged at intervals, and perpendicular to the bottom surface of the sole; and the keel is fixed at the heel part of the sole. The utility model has the advantages that the manufacturing cost is low, the manufacturing process is simple, the sole is hard enough to bear the weight of the human body and has elasticity, and the weight is light.

Description

Dual-density rubber one-shot forming sole

Technical field

The utility model relates to dual-density rubber one-shot forming sole.

Background technology

The footwear of being worn in people's life divide roughly, and branch can be divided into three layer of first sole, second middle level, the 3rd vamp, why being divided into three layers substantially is because these three layers function and usage difference separately, there is enough hardness to support human weight such as requiring in this layer of sole of high-heeled shoes, so the density of material is higher than other layer, but so the overall weight of footwear has just increased the weight of, and walk and do not have what elasticity, the sound of walking on hard floor can be bigger, brought inconvenience and uncomfortable feeling when wearing shoes in daily life so just for people.

Summary of the invention

The purpose of this utility model is a dual-density rubber one-shot forming sole, and it can reach to satisfy under the hardness that supports human body weight and make sole have elasticity, has improved people's degree comfortable and easy to wear, and one-shot forming, has simplified manufacturing process.

Technical solution of the present utility model is that it particularly has keel on the basis of sole, keel and sole single injection-molded, described keel are made up of a main bone and the osteocomma parallel to each other and separated by a distance that is no less than a slice, osteocomma is vertical with the bottom surface of sole, and keel are fixed on spring heel portion.

Uncovered space can be rectangle, circle, triangle or prismatic between the osteocomma on the above-described keel.

It is short that osteocomma described in the utility model has height to have, and for the highest, short more the closer to toe cap portion, arranged vertical successively at the heel of sole.

Manufacture method of the present utility model is, high density PU material is injected in the keel district in holding mould successfully, other position is injected relative low-density and is had certain flexible PU material, make the one-shot forming in manufacture process of sole and keel, make sole have enough support forces to support human weight, leaving the space between osteocomma on the keel and the osteocomma makes the overall weight of sole reduce, surround keel with the resilient material of one deck again at the sole heel, flexible when shoes are worn, the anti-skidding and little effect of sound the when comfort level of increasing dress and walking.

The utility model has the advantages that low cost of manufacture, manufacturing process is simple, has elasticity when can make sole that enough support human body weights is arranged, and in light weight.

The specific embodiment

Implementation column 1

Shown in Fig. 1,2, the utility model has keel 2 on sole 1 basis, keel 2 and sole 1 single injection-molded, described keel 2 are made up of a main bone 3 and six osteocomma parallel to each other and separated by a distance 4, osteocomma 4 is vertical with the bottom surface of sole 1, and keel 2 are fixed on sole 1 rear heel.It is short that osteocomma 4 has height to have, and for the highest, short more the closer to toe cap portion, arranged vertical successively at sole 1 heel.

Implementation column 2

Basically with embodiment 1, different places is that uncovered space is circular between the osteocomma 4 on the described keel 2.

Implementation column 3

Basically with embodiment 1, different places is that uncovered space is a triangle between the osteocomma 4 on the described keel 2.

Implementation column 4

Basically with embodiment 1, different places is that uncovered space is a prismatic between the osteocomma 4 on the described keel 2.
