Problems solved by technology

[0008] However, since the sole unit 2 and the outer edge strip 1 of the aforementioned patent are all prefabricated and solid and then stitched together, the amount of plastic deformation is quite low, so this type of shoes is relatively monotonous in appearance, unless it is After the foam material is hardened, the whole shoe is put into the mold and hot-pressed to form a three-dimensional outline and texture on the outer surface of the shoe periphery, but this will increase the cost
On the other hand, the cavity 5 must be a non-open space to accommodate the injected foam material, so that the sole unit 2 must be made into a full-foot shape. Therefore, this method of manufacture can only The only way to make single-color soles is to paint the soles after they are shot and demolded, but this will also increase the cost

Embodiment Construction

[0064] refer to Figure 2-5 As shown, the manufacturing method of the foamed shoe body of the present invention, a first preferred embodiment includes the following steps:

[0065] 1. Preparation of a shoe upper component 10 and an elastic module 20: the shoe upper component 10 is formed by combining more than one piece of elastic and stretchable material in a sewing manner, and has a top opening 11 at the top edge, an outer surface around the outer circumference 12, and a sole pad 13 located at the bottom of the upper assembly 10 and connected to the outer surface 12. In this embodiment, the elastic module 20 is made into an independent block corresponding to the shape of the rear heel of the human body, and the elastic The module 20 has a bottom surface 21 , an outer surface 22 surrounding the bottom surface 21 , and a material injection area 23 recessed on the bottom surface 21 .

[0066] 2. Paste (spray) the overflow material isolation layer: an isolation layer 14, 24 is ...

Abstract

A technology for integrally preparing the foamed shoe body includes putting a shoe upper assembly on shoe last and an elastic module in a mould to form an open concave cavity consisting of the bottomsurface of said shoe upper assembly and the inner surface of mould, filling the liquid foaming material in the cavity, closing the mould, and foaming. Its advantages are low cost, and high quality ofproduct.

Description

【Technical field】 [0001] The invention relates to a manufacturing method of footwear, in particular to a method for integrally forming foamed shoe bodies that can reduce costs, improve product quality, and is suitable for multi-color and elastically variable sole products. 【Background technique】 [0002] In the past, it was easier to control the foaming of EVA molding for soles with simple and simple shapes. The sole is divided into two parts, the midsole and the outsole, and each part is produced separately, and then chemically glued separately, so the manufacturing process is more troublesome and wastes time. [0003] U.S. Patent No. 4,245,406 discloses a method of making sports shoes by liquid injection, which is to embed a pre-treated rubber outsole on a bottom mold, and then set a shoe upper on a On the shoe last, and then move the shoe tree down, so that a material injection space is formed between the shoe last and the rubber outsole, and then the measured PU foam ma...
