Molding method of foamed sole with concolorous, dissimilar properties wearable area

Abstract

This invention relates to a foam shoe sole shaping method with same color and foreign matter wearing area, which comprises the following steps: processing beforehand a hard and wearing embryo and preparing heat pressure foam module; putting the embryo roughly into one module cave and filling the large base initial embryo with same color and different matter into the module cave; the large base embryo and embryo pad trigger the foam and crossing reactions under the foam sustaining temperature; getting the product through module opening, cooling after the reactions.

Description

technical field [0001] The invention relates to a molding method for shoe soles, in particular to a molding method for foaming shoe soles with the same color and foreign body wear-resistant regions. Background technique [0002] Such as figure 1 As shown, there is an existing molding method that can be made into various properties of shoe soles, which is to prepare several sheet-like blanks 1 in advance by molding, and prepare a lower mold 201 and an upper mold 202 that are kept at 170 The mold 2 with a reaction temperature of ℃~190℃, a top surface of the lower mold 201 is concavely provided with a mold cavity 203, and a mold bottom surface of the mold cavity 203 is convexly provided with a number of partition walls that can respectively define an accommodating groove 205 204 , the accommodating groove 205 is just for the embryo material 1 to be placed in, and the embryo material 1 is positioned by the partition wall 204 . [0003] When wanting to form a shoe sole, the bla...

Problems solved by technology

[0005] 1. Because the mold 2 itself is constantly maintained at the temperature (170°C-190°C) that can supply the main material part and the blank material 1 reaches the foaming and cross-linking reaction, so when the blank material 1 is put into the storage tank 205, Immediately affected by the temperature of the mold 2, foaming and cross-linking reactions may have begun in a local area, and even warping and deformation will occur. 1 overflow outside the storage tank 205 or shift, resulting in defective products

[0006] 2. Because the temperature of the mold 2 is quite high, it is indeed difficult to operate the embryo material 1 and the holding tank 205 accurately in a short period of time, and there is a danger of burns

[0007] 3. Due to the different sizes of foamed soles, the size of the embryo material 1 must change accordingly, so the production and material management of the embryo material 1 are more troublesome
