Shock absorption and ventilation shoe sole

Abstract

The invention relates to a shoe sole and provides a shock absorption and ventilation shoe sole. According to the shock absorption and ventilation shoe sole, the number of shoe sole gluing procedures is reduced, the production cycle is shortened, glue treating agents are not needed, hazardous substances and environment pollution are reduced, and mass production is facilitated. The shock absorption and ventilation shoe sole comprises a rubber midsole and a rubber outsole, and the rubber midsole and the rubber outsole are shaped by placing unvulcanized rubber in molds, heating the rubber in a medium well mode and vulcanizing the rubber. The rubber midsole is of a hollowed-out frame shape formed by n-shaped parts, the n-shaped parts are uniformly arranged in the transverse direction of the rubber midsole side by side, vent holes are formed in convex platforms of the n-shaped parts, and connecting portions between the adjacent n-shaped parts constitute concave platforms. An unvulcanized rubber sheet is further arranged between the concave platforms of the rubber midsole and the rubber outsole, the concave platforms are covered with the unvulcanized rubber sheet, and the unvulcanized rubber sheet is covered with the rubber outsole. The rubber midsole, the unvulcanized rubber sheet and the rubber outsole are integrally formed through in-mold vulcanization again.

Description

technical field [0001] The invention relates to a shoe sole, in particular to a shock-absorbing and ventilating shoe sole. Background technique [0002] Shoes are indispensable daily necessities in people's daily life, and sole is an important part of shoes. The sole in the prior art generally comprises big bottom and midsole, and the big bottom of shoes generally adopts the better rubber material of abrasion resistance, and in order to increase the elasticity and comfort of shoes, the midsole of shoes generally adopts comparatively soft EVA material, Because the materials of the outsole and the midsole are different, the traditional process of making the sole is generally to first foam the EVA midsole and make the rubber outsole at the same time, and then manually glue the midsole and the outsole through glue, In the process of bonding, first remove the burrs on the outsole and midsole, then apply a treatment agent on the bonding surface of the outsole and midsole, and the...

The sole in the prior art generally comprises big bottom and midsole, and the big bottom of shoes generally adopts the better rubber material of abrasion resistance, and in order to increase the elasticity and comfort of shoes, the midsole of shoes generally adopts comparatively soft EVA material, Because the materials of the outsole and the midsole are different, the traditional process of making the sole is generally to first foam the EVA midsole and make the rubber outsole at the same time, and then manually glue the midsole and the outsole through glue, In the process of bonding, first remove the burrs on the outsole and midsole, then apply a treatment agent on the bonding surface of the outsole and midsole, and then glue them together. At the same time, carefully seal the edges of the outsole and midsole Alignment, to avoid affecting the appearance of the product due to inaccurate fit, so this traditional method of making the sole by bonding the EVA midsole and the rubber outsole through glue, the entire production process requires a lot of manual operations, which is not only time-consuming and labor-intensive, but also improves production efficiency. It is also easy to cause quality problems such as misalignment of the edges of the outsole and midsole or glue opening, which is not conducive to mass production, and the cost is high and the production cycle is long. At the same time, the treatment agents and glue used in the production process generally contain harmful substances and emit harmful substances. Gas, which pollutes the environment and causes harm to workers' bodies
