One-piece molded shoe sole and its manufacturing mold and production method

Abstract

The invention discloses an integrally formed shoe sole, which comprises a foam-molded midsole and a non-foamed outsole; the midsole is attached to the outsole and integrally formed with the outsole. The shoe sole is integrally formed in the same mold, does not require lamination procedures, has fewer procedures, and lower cost; it has a long service life, light specific gravity, good elasticity, excellent shock absorption effect, and high wearing comfort. The present invention also provides a mold for integrally forming shoe soles. The mold is provided with outsole and midsole cavities at the same time, which can realize one-time pouring and molding of shoe soles. The mold has a simple structure and a reasonable pattern, and the produced shoe soles are beautiful. High yield. The present invention also provides a production method for integrally formed shoe soles, low-temperature molding, simple process, convenient operation, time-saving and labor-saving, environmental protection and safety; and no need for color spraying operation, the sole with two-color effect can be formed, the process is simple, energy saving and emission reduction .

Description

technical field [0001] The invention relates to the technical field of shoe manufacturing, in particular to an integrally formed shoe sole, a manufacturing mold and a production method thereof. Background technique [0002] Shoes can protect people's feet well, especially, shoes can reduce or avoid the shock force that people walk or run, and avoid spinal nerves from being injured. The sole generally includes an outsole and a midsole. The outsole is in direct contact with the ground and has good wear resistance; while the midsole is arranged on the outsole, which can play a good shock-absorbing effect. The sole is closely related to the health of the body, therefore, its molding structure and production method are particularly important. [0003] In today's shoe-making industry, the production of shoe soles requires a complex process, including the use of outsole molds to produce outsoles, the use of midsole molds to produce midsoles, and then roughening the surface of the ...

AI Technical Summary

Problems solved by technology

If the product is a foam-molded midsole, although the advantage of good elasticity can be obtained, the midsole is not wear-resistant and needs to fit the outsole to be used; if the product is a foam-molded outsole, although it is wear-resistant, it has no elasticity

That is to say, this production method cannot take into account the two points of wear resistance and elasticity at the same time, and, no matter whether the product is a midsole or an outsole, neither can see the internal spring, which is not beautiful
