Abstract

The utility model relates to a dual-density Goodyear outsole comprising an outer layer, wherein a foaming rubber inner layer is arranged on the outer layer, the foaming rubber inner layer and the outer layer are compounded as a whole, and a groove is arranged in the inner layer. The dual-density Goodyear outsole adopts one-time vulcanizing process to fundamentally solve the combination problem of foaming rubber and solid wear-resistant rubber at the outer layer. The vulcanizing process is detailed as follows: the solid rubber at the outer layer is put in a flat vulcanizing mold, the mold is opened when the outer-layer rubber vulcanizing is basically finished (by about 80%), the vulcanized outer-layer rubber sole is put another mold, then proper foaming rubber is added, the mold is closed and pressurized, and the mold is opened after the vulcanizing is finished.

Description

The solid special big end of dual density

Technical field

The utility model relates to the big end of a kind of footwear, relates to a kind of solid special big end specifically.

Background technology

Special Gu (Goodyear) structure, what continue to use is the vocabulary of rubber industry, and it is a kind of special sole processing technology.Adopt advanced linear slit to add bonding technique, utilize and upper of a shoe and sole are combined closely along the end in bar and the rubber.Run-of-the-mill of the big end of this rubber is heavier, and it is more heavy that dress is got up, and the rubber that uses in the production process is more, and cost is higher.When entire body was used a kind of rubber, inner high performance rubber did not produce use value to the sole quality, and had strengthened the manufacturing cost that becomes footwear.

Summary of the invention

The purpose of this utility model just is to overcome above-mentioned deficiency provides a kind of dual density the solid special big end.

The purpose of this utility model can be achieved through the following technical solutions:

The solid special big end of a kind of dual density, comprise skin, and the bipeltate internal layer is set on skin, and the bipeltate internal layer is compound with skin to be one.

The solid special big end of above-mentioned dual density,, described internal layer is provided with groove.

The solid special big end of above-mentioned dual density,, described groove is symmetricly set on the heel region of internal layer.

Adopt technique scheme, the utility model has following advantage: the solid big end of special rubber of dual density, is when satisfying solid specific structure processing technology, the big end of rubber of original entity, made into outer for high performance wear-resisting, anti-skidding solid rubber, internal layer is that density is lighter, and the bipeltate of the modulus intensity of solid rubber is arranged again simultaneously.Quite original weight of the solid big end reduces by 30% at the rubber of this dual density big end, and improves the elasticity of rubber soles greatly, increases degree comfortable and easy to wear.Because inboard bipeltate can the relatively low elastomeric material (mainly being the anti-wear performance that has reduced internal layer) of use cost, thereby cost of the big end of whole rubber is reduced.

Disposable sulfuration process is adopted at the solid big end of special rubber of this kind dual density, fundamentally solve bipeltate and outer field solid abrasive rubber in conjunction with problem, concrete sulfuration process is as follows: the mould of outer solid rubber being put into compression molding, treat that outer layer rubber vulcanizes (sulfuration finishes about 80%) die sinking when finishing substantially, another one mould the inside will be put at the bottom of the outer layer glue that vulcanizate, add an amount of bipeltate then, matched moulds pressurization, treat sulfuration finish after die sinking.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the utility model schematic cross-section.

The specific embodiment

The solid special big end of a kind of dual density as depicted in figs. 1 and 2, comprise outerly 1, on outer 1, bipeltate internal layer 2 be set, bipeltate internal layer 2 with outer 1 compound be one, be provided with groove 3 at the bipeltate internal layer, groove 3 is symmetricly set on the heel region of bipeltate internal layer.

The utility model can make the outer solid abrasive rubber that is, internal layer is that density is 0.7gcm ^-3To 0.9gcm ^-3Bipeltate.

The utility model can make the outer colored solid rubber that is, internal layer is that density is 0.7gcm ^-3To 0.9gcm ^-3The black bipeltate.

The utility model can make the outer colored solid rubber that is, internal layer is that color and density different with skin is 0.7gcm ^-3To 0.9gcm ^-3Colorful rubber.
