Damping sole

Abstract

The invention relates to a damping sole which decreases sole laying processes, shortens production cycle, omits glue treatment agents, reduces hazardous substances and environmental pollution and facilitates mass production. The damping sole comprises a rubber outsole and a rubber insole, unvulcanized rubber is placed in a die and heated to medium well to form the rubber outsole and the rubber insole, a filling groove is formed in the rubber insole, exhaust holes are formed in the groove bottom of the filling groove, the inside of the filling groove is filled with elastic materials, an unvulcanized rubber piece is arranged between the rubber outsole and the rubber insole and covers a notch of the filling groove in the rubber insole, the rubber outsole covers the unvulcanized rubber piece, and the rubber insole, the unvulcanized rubber piece and the rubber outsole are vulcanized in the die again and then integrally formed.

Description

technical field [0001] The invention relates to a shoe sole, in particular to a shock-absorbing 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 then glue them tog...

Problems solved by technology

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
