Abstract

The invention discloses a preparation method of a double-density-layer middle sole. The preparation method comprises the following steps: (1) preparing a hard material mold and a soft material mold, wherein the hard material mold is provided with a groove corresponding to a predetermined lower layer skin thickness, and the soft material mold is provided with a groove corresponding to the sum of the predetermined lower layer skin thickness and an upper layer skin thickness; (2) starting an injection molding machine, carrying out injection molding on a hard material with a given hardness to the groove corresponding to the predetermined lower layer skin thickness at the temperature of 200 to 220 DEG C and the pressure of 80 to 100KG so as to obtain a lower layer semi-finished product with a given hardness; (3) arranging the lower layer semi-finished product into the groove of the soft material mold, carrying out injection molding on a soft material with a given hardness for the lower layer semi-finished product in the groove of the soft material mold at the temperature of 190 to 220 DEG C and at the pressure of 80 to 100KG so as to obtain the middle sole with a hard lower layer and a soft upper layer. The invention also provides a product prepared by the method. By adopting the preparation method, not only can the comfortable wear-resistant middle sole be prepared, but also the preparation method has the advantages that the environment-friendly effect is achieved, and the working efficiency and the product quality can be greatly improved.

Description

technical field [0001] The invention relates to a preparation method of a shoe midsole, in particular to a preparation method and a product of a double-density layer shoe midsole. Background technique [0002] Comfortable and durable shoes are always pursued by people. The forefoot and sides of the shoes should be soft to ensure comfortable wearing; while the waist, arch and heel of the shoes should be hard, otherwise they cannot support the weight of the human body and cause the human body to become unbalanced and easily deformed. and damage, the existing shoe midsoles are all three-in-one, that is, use hard red cardboard or gray cardboard and soft yellow cardboard or non-woven fabric to add iron core to support the waist of the shoe, so as to prevent the shoe from being unable to support the body weight when running and jumping shock. [0003] Although the strength of the traditional midsole is sufficient, the comfort is very limited; at the same time, the existing multi-...
