Embodiment Construction

[0025] The technical process of neoprene double-density injection shoemaking of the present invention is after the upper making process is finished, with reference to figure 1 The technological process shown completes the sole making and the combined assembly with the shoe upper. For the slope structure diagram of the shoe, see figure 2 . Specifically:

[0026] 1) Stretch the upper corner 11 of the upper 1 on the inner sole 2 according to the shape of the sole, and wrap the upper corner 11 on the inner sole 2, then heat setting (the temperature of the vacuum heat setting machine is controlled at 95±5°C, and the drying time is 30~ 40 minutes), and then cold setting (the temperature of the vacuum cold setting machine is controlled at -5 ~ 15 ° C, and the time is controlled at 8 ~ 25 minutes); then the inner thread is sewed, and the inner bottom 2 corners 11 are sewed;

[0027] 2) Paste the rubber strip 3 along the upper corner 11, then stick the midsole 4 on the strip 3, nail...

Abstract

The invention relates to a method for shoemaking by neoprene double-density injection. The method comprises the steps as follows: 1) after an upper, an inner sole and a middle sole are fixed in sequence, a small rear palm is nailed at the position of the heel of the middle sole to form a semifinished product of shoes; 2) dense glue is injected to a sole-centered die cavity for the first time, after a second last and a sole die are matched to be heated and pressed, the second last is removed to form a solid glue layer; then foaming adhesive is injected for the second time, an aluminium foot sheathed with the semifinished product of the shoe is put into the die cavity for matching moulds, heating and pressing, and a shoe blank is formed after mold stripping; 3) the shoe blank is processed for cold forming after being built with water gap glue, and the shoe is processed for subsequent treatment to obtain a finished product. A big sole of the invention comprises the solid glue layer and a foaming layer, thereby satisfying the wearing resistance and the strength requirement and also greatly reducing the weight of the sole simultaneously; the design of the grain of the big sole ensures that the thicknesses of the solid glue layer at different positions are changed to completely cater to the strength distribution characteristic when people walk; the heel of the shoe is added with the small rear palm, so the hardness at the heel is adjusted effectively. The finished product of the shoe manufactured by the invention has good forming performance and is substantial, firm, light and comfortable, and the method is suitable for manufacturing functional shoes.

Description

Technical field: [0001] The invention belongs to the field of daily necessities manufacturing, and specifically relates to a shoe-making method, in particular to a manufacturing method of high-quality functional shoes and the structure of the functional shoes. Background technique: [0002] Shoes are the most commonly used daily necessities for people. The traditional shoe-making process is to prepare the upper and the sole separately, and then apply adhesive, sew, put on the last, heat, squeeze and bond to shape. The disadvantage is that it is easy to degumming and separation after wearing for a period of time. , poor firmness. The sole is generally divided into multiple layers of different materials, which can be made by injection molding of rubber materials. For example, 01105433.6 discloses a shoemaking method of multi-material integral molding. The process includes infiltration and mixing, melting injection, second injection, Place and pour, mix the coupling agent and...
