Problems solved by technology

[0002] As we all know, the shoe outsole is one of the shoe parts that affect the walking comfort of human feet. The poor softness and heavy weight of the shoe outsole will seriously affect the wearing comfort of the shoe, and the shoe outsole produced by the traditional manufacturing process has a high density. Wear resistance, aging resistance, corrosion resistance and tear resistance are poor. In order to solve the above problems, the industry has developed a foaming process to produce shoe outsoles. Influenced by the structure and the problems of the foaming process itself, a large amount of gas is generated in the mold during foaming. If it is not discharged, the finished foam shoe outsole will have a large number of large cells from the inside to the outside. Existence will seriously affect the appearance of the outsole, and the wear resistance and tear resistance are poor
[0003] In order to exhaust the gas, some manufacturers have installed exhaust grooves at the junction of the mold, but the exhaust grooves can only discharge the gas near the exhaust grooves, and the gas in the part far away from the exhaust grooves cannot be discharged in time, and the exhaust The groove is also easily blocked, affecting the normal discharge of gas

Embodiment 1

[0011] Embodiment 1: The production process of the outsole of shoes, the production process is as follows: a. Melt the main material rubber or polyurethane; b. Prepare the cotton rope 1, and the cotton rope 1 is hung in the position between the male pillars 3 of the upper mold 2 in advance place, such as figure 1 As shown, the length of the cotton rope 1 should be based on the fact that both ends of the rope can be exposed to the outside after the mold is closed, so as to ensure the normal progress of the exhaust; c. The agent, foaming agent and foaming aid are injected into the lower mold 4 together; d. Clamp the molds and heat vulcanization for molding.

Embodiment 2

[0012] Embodiment two: the production process of shoe outsole, its production process is as follows: a. melt main material rubber or polyurethane; b. prepare cotton rope 1, and cotton rope 1 is placed in lower mold 4 in advance, as figure 2 As shown, the length of the cotton rope 1 should be based on the fact that both ends of the rope can be exposed to the outside after the mold is closed, so as to ensure the normal progress of the exhaust; c. The agent, foaming agent and foaming aid are injected into the lower mold 4 together; d. Clamp the molds and heat vulcanization for molding.

[0013] Cotton rope is used here because the cotton rope is extremely soft, and the addition of a small cotton rope will not affect the combination of the upper mold and the lower mold, and the cotton rope is good at absorbing liquid and gas, so it is very suitable for absorbing and guiding the inside of the mold The gas is discharged to the outside. After molding, the cotton rope will be hidden ...

Abstract

The invention discloses a shoe outsole production technology. The shoe outsole production technology includes the manufacturing steps of a, fusing a main rubber material or polyurethane; b, preparing cotton cords which can be preplaced on a lower mould body or hung on an upper mould body in advance; c, injecting the fused main material with a vulcanizing agent, a foaming agent and a blowing promoter in a mould; d, combining the upper mould body with the lower mould body, heating and vulcanizing to shape. By the technical scheme, the shoe outsole has the advantages that by means of adding a cotton cord placing step, gas guiding performance of the cotton cords is utilized, gas generated during foaming shaping can be vented timely and uniformly, uniformity of foaming and shaping is guaranteed, a shoe outsole with tiny small foaming holes can be obtained, and abrasive resistance, tear resistance and attractive appearance of the shoe outsole can be improved greatly.
