Integrally-molded shoe sole and manufacturing mold and production method thereof

Abstract

The invention discloses an integrally-molded shoe sole. The shoe sole comprises an insole molded through foaming and an outsole molded without foaming. The insole is attached to the outsole, and the insole and the outsole are integrally molded; the shoe sole is integrally molded in one mold, the attaching program is not needed, the number of working procedures is small, and the cost is low; the service life is long, the specific gravity is small, elasticity is good, the damping effect is excellent, and wearing comfort is high. The invention further provides a manufacturing mold of the integrally-molded shoe sole. The mold is provided with an outsole cavity and an insole cavity at the same time, one-time casting molding of the shoe sole can be achieved, the mold is simple in structure and reasonable in layout, the produced shoe sole is attractive and high in yield, and the invention further provides a production method of the integrally-molded shoe sole. Low-temperature molding is achieved, the flow process is simple, operation is convenient, time and labor are saved, and the shoe sole is environment-friendly and safe; color spraying operation is not needed, the shoe sole with the dual-color effect is formed, the working procedure is simple, and energy saving and emission reduction are achieved.

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
