Abstract

The new type shoe sole is composed of rubber bottom layer and plastic sub bottom layer. The vulcanized rubber bottom layer and injection moulded plastic sub bottom layer are tenon combined into a single body. This composite shoe sole retains the elasticity of vulcanized rubber which is fastness to abrasion and wear, and retains the lightness and softness of plastics.

Description

At the bottom of the novel assembled shoe and production method

The invention belongs to a kind of sole of shoe and production method.

Dress now has rubber-sole and plastic bottom two major types with the sole of footwear, and rubber-sole elasticity and anti-wear performance are better, but the secondary metallization processes in its production process is comparatively complicated, and investment of production equipment is bigger; The plastic sole quality is lighter, and plasticity is good, and production technology and equipment are corresponding comparatively simple, but that its elasticity that contacts with ground and wear-resisting, anti-tearing involve performance is poor slightly.

Purpose of the present invention promptly is to propose at the bottom of a kind of novel assembled shoe and production method, makes it have the advantage of rubber and two kinds of material products of plastics and the advantage of two kinds of technologies is embodied a concentrated reflection of on the goods.

Be to constitute at the bottom of the assembled shoe of the present invention by the different sole of two kinds of materials of the inferior bottom of rubber bottom and plastics, be utilize rubber plate vulcanization and plastic injection-moulded two kinds of different process that rubber bottom and plastics Asia bottom are constituted novel assembled shoe at the bottom of.

The inferior bottom of the bottom of rubber material and plastics adopts firm tenon type structure to be combined into one at the bottom of the assembled shoe of the present invention.

It at the bottom of the assembled shoe of the present invention the injection mould that places sole by designing requirement at the bottom of the rubber-moulding that makes with compression molding technology earlier, on the bottom of rubber material, constitute the inferior bottom of plastics by Shooting Technique then, and bottom and inferior bottom is combined integrated, simultaneously with fudger week and footwear nation lower edge also injection moulding formation one.

In at the bottom of the assembled shoe of the present invention, rubber-sole is contacting with ground down, can keep the characteristics at the bottom of the rubber post-cure fully, as good springiness, and forming and clean mark, wear-resisting, the anti-tractive etc. that tears; Plastic bottom contacts with sole last and form one with the lower edge of rubber-sole and limit week and footwear nation, also can keep the characteristics of plastic bottom fully, and light and soft as quality, plasticity is good, and is workable, produces in enormous quantities superior etc.

In specific words, advantage of the present invention is:

(1) adopt sulfuration and two kinds of technology manufacturings of injection moulding at the bottom of the assembled shoe, these two kinds of technology combinations under given conditions embody a concentrated reflection of on the goods advantage of two kinds of technologies, are a kind of breakthroughs to the method at the bottom of traditional shoemaking, have realized technological progress.

(2) at the bottom of the assembled shoe be the combination of two kinds of unlike material goods, compound artifact concentrates collection to show the advantage of two kinds of unlike material goods, has obtained the effect that is better than each built-up section, has improved product quality, class.

(3) dovetail type structures is adopted in combination, can once be finished by injection moulding, is more conducive to industrial mass manufacture.

(4) bonding of sole and footwear nation can realize by injection moulding, has replaced the manual operations that bonds with group in the production of rubber-sole footwear.

(5) production at the bottom of the assembled shoe, saved indispensable post-cure Processes and apparatus in the rubber-sole footwear production process, only a compression molding rubber-sole is passed through injection process, can obtain the characteristics of rubber post-cure sole fully, improve product quality, reduced cost, strengthened the market competitiveness.

(6) because plastics are littler than the elasticity of rubber, rubber-sole is subjected to the constraint of the comprehensive power of horizontal direction in the area that is slightly less than itself that is surrounded by tenon formula junction, make when step rises and falls, the elastic energy of rubber-sole is fully brought into play on above-below direction, gives the sensation of soft power-assist.

In a word, two kinds of technology combinations under given conditions, the ingenious combination of two kinds of material products, utilization of dovetail type structures or the like, make at the bottom of the new product assembled shoe on the development of technology, in the simplification of Processes and apparatus, in the raising of quality, in the reduction of cost, in the creation of mass production environment, in the enhancing of the market competitiveness, this or the like the aspect, all be better than simple rubber soles and plastic sole, have the characteristics of tangible novelty, creativeness, practicality.

Embodiment:

Accompanying drawing provides assembled shoe bottom structure schematic diagram of the present invention;

Shown in the accompanying drawing: the upper surface periphery of rubber bottom 1 is a tenon shape groove 2, and inferior bottom 3 and its of plastic material are integrated for tenon shape structural group, and forms one with fudger week 4 and the lower edge injection moulding of footwear nation.

Preparation method of the present invention:

Utilization rubber plate vulcanization technology is made required rubber-sole by mould, the shoemaking injection mold is transformed on demand, even it has the position of placing rubber-sole in the bottom; With rubber-sole give heat to the injection mould isothermal, and rubber-sole is positioned in the injection mold in advance, the utilization Shooting Technique is finished the combination of plastic bottom and rubber-sole, finishes combining of footwear nation and sole simultaneously.

Claims

1, at the bottom of a kind of novel assembled shoe, feature of the present invention is to be to be constituted by the bottom (2) of the rubber material inferior bottom (3) with plastic material at the bottom of the assembled shoe, and bottom (2) and inferior bottom (3) adopt firm tenon type structure to make up.

Production method at the bottom of a kind of novel assembled shoe, feature of the present invention is the injection mold that adopts rubber plate vulcanization technology to make required rubber-sole and rubber-sole is placed sole, form the inferior bottom and itself and rubber bottom is combined integrated of plastics by Shooting Technique, simultaneously fudger week and footwear nation lower edge are also formed one.

2, according at the bottom of the described novel assembled shoe of claim 1 and production method, feature is that design has the position of placing rubber-sole in the plastics injection mould.
