Problems solved by technology

[0008] However, if the above-mentioned manufacturing method (Taiwan Patent No. 425271) is applied to finished soles with multi-color systems and materials, it is difficult for rubber or EVA block bodies 101, 102, 103 to be placed in after being heated to a high temperature state. In-mold thermoforming (due to inaccurate alignment), so the aforementioned manufacturing method is not suitable for multi-color shoe soles integrated into the mold for hot pressing

Embodiment Construction

[0025] refer to figure 2 , 3 As shown, the first preferred embodiment of the manufacturing method of foamed shoe body integral molding of the present invention includes the following steps:

[0026] 1. Preparation of a shoe upper component and a shoe sole unit: the shoe upper component 10 is formed by combining more than one piece of material by sewing, and has a top opening 11 at the top edge, an outer surface 12 surrounding the outer circumference, and A bottom surface 13 located at the bottom of the shoe upper assembly 10 and connected to the outer surface 12, the sole unit 20 in this embodiment includes a foamed EVA shoe midsole blank 21 and a preformed shoe outsole 22, wherein the shoe midsole embryo 21 is a semi-finished product with a size slightly larger than the finished product, and has a top surface 211 and a side wall 212 extending upward from the periphery of the top surface 211. The two cooperate to define a chamber 213 that can accommodate objects.

Abstract

A method for integrally forming the foamed shoe body includes such steps as putting an upper assembly and a sole unit with foamed insole in a die, introducing the heat flow in the circulating channel in the die for raising its temp. and hot pressing. Its advantages are low cost and high productivity.

Description

【Technical field】 [0001] The invention relates to a manufacturing method of footwear, especially suitable for shoes with simple shoe shape and thinner sole, so as to facilitate the manufacturing method of the shoe body which is integrally formed when it is directly heat-pressed by a mold at normal temperature. 【Background technique】 [0002] In the past, it was easier to control the foaming of polyolefin plastic (EVA) for simple and simple shapes of soles. However, with the diversification of three-dimensional (3D) shapes of shoe bodies today, the foaming technology of soles has become more complex. Difficult, therefore, at present, the shoe-making industry often divides the sole into two parts, the midsole and the outsole, and each part is produced separately, and then chemically glued. [0003] U.S. Patent No. 4,960,374 is requesting a shoe body forming device, which can form a closed shoe trim at the seam between the upper and the outsole, which is to put the upper on the...
