Abstract

A method for making shoe soles includes coating liquid adhesive on cloth, sticking a film, layering aside for a certain time, cutting for shaping, putting it in sole mould in such manner that the cloth is close to the bottom of mould, pouring the liquid raw material in the mould, and solidifying.

Description

A kind of manufacture method of sole

Technical field

The present invention relates to the manufacturing of sole, relate in particular to a kind of manufacture method of patch sole.

Background technology

The sole of shoes that people wear mostly is that tartan is made and very hard, and sole is easy of causing damage in the floor of costliness with the floor collision when being in walking placed in the middle, and sole and ground friction cause wearing and tearing to sole easily when walking in the street.Existing solution is to stick cloth at the forefoot of sole and heel place, and what so contact with ground with the floor is the cloth cover of softness, not only can avoid damaging the floor of urban human household, and can protect sole not by harder ground surface wear.

At present, first kind of method in the sole patch is directly cloth to be placed in the mould to pour into material forming again in mould, cooling back sole combines with cloth and with the bottom of cloth attached to sole, and still raw material can permeate cloth cover and influence the pliability and the outward appearance of sole cloth cover in filling process.Second kind of method in the sole patch is that outer subsides mode is fitted, make sole earlier, handle with solvent in the bottom surface then, last twice glue in baking back, all need stick cloth again through the overbaking program after having gone up glue, because aforementioned operation is manually-operated substantially, there is following shortcoming in this method: (1) solvent is a petroleum solvent at every turn, volatile in air when processing, baking, easily damaged by the human body suction; (2) operation is miscellaneous, repeatedly, waste of manpower, material resources and electric power; (3) cloth accurately can't be affixed on the tram, pull-up is heavily pasted and is easily caused cloth cover to damage and scrap when mistake is pasted, thereby has increased production cost; (4) gluing and patch operation need be finished and easily polluted sole, rework rate height by 4 staff.

Summary of the invention

At the shortcoming of prior art, the invention provides a kind of manufacture method of sole, solved sole when form, raw material can not permeate cloth cover, and makes combining closely more between cloth sheet and the sole bottom surface.

To achieve these goals, technical scheme of the present invention is: a kind of manufacture method of sole, it comprises the steps:

(1) cementing and stick film on the cloth sheet;

(2) the cloth sheet that is fitted with film is cut out required shape after leaving standstill a period of time, place in the die for shoe-sole then, and make and be fitted with one of film and face up, and another side is adjacent to bed die;

(3) liquid charging stock that will make sole is poured into in-mold molding, thereby and the bottom surface of the sole after the moulding with the film fluid-tight engagement cloth sheet is combined with sole.

Described film is a polyurethane film.

At the bottom of described sole is polyurethane shoes.

In step (1), be by gluing abutted equipment cementing and stick film on the cloth sheet, after hot pressing, fit together.

In step (2), be to leave standstill again after the cloth sheet is rolled.

In step (2), the time of repose of cloth sheet is no less than 24 hours.

Compared with prior art, the invention has the advantages that: after adopting manufacture method of sole of the present invention,, personnel are injured low by the gluing of gluing abutted equipment; The cloth sheet directly placed in the mould pour into, can accurately paste accurate position; And the loss of human and material resources is lower; By being fitted with film on the cloth sheet, the effect of obstruct is arranged, so liquid charging stock can't penetrate cloth cover, kept the neat and tidy of cloth cover.

Description of drawings

The present invention is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a mould cross-sectional schematic of the present invention.

Fig. 2 is the upward view of sole of the present invention.

Fig. 3 is the A1-A2 cutaway view of Fig. 2.

The specific embodiment

See also Fig. 1, the mould that the manufacture method of sole of present embodiment uses is made up of mold 1 and bed die 2, forefoot position and the even distribution several cylinders body 3 and 4 of heel position difference at mold 1 inner face offer two grooves 5 and 6 that are used to place the cloth sheet respectively at bed die 2 forefoot positions and heel position.The manufacture method of sole of present embodiment comprises the steps:

(1) by gluing abutted equipment (model that can select the Shanghai ancestor to believe that plant equipment Co., Ltd sells is the make-up machine of HR-800) cementing and stick polyurethane film (polyurethane film that can select Taiwan Jie Xin limited company to sell) on the cloth sheet, after hot pressing, fits together;

(2) leave standstill after 24 hours after the cloth sheet that will be fitted with film is rolled and cut out required shape, be positioned over respectively in the groove of bed die forefoot position and heel position then, and make and be fitted with one of film and face up, and another side is adjacent to bed die with die;

(3) the Polyurethane liquid charging stock that will make sole is poured in the sole-shaped space that upper and lower mould forms and moulding, thereby the bottom surface of the sole after the moulding combines the cloth sheet with the film fluid-tight engagement with sole.

See also Fig. 2 and Fig. 3, bottom surface at the forefoot position of sole main body 7 is provided with cloth sheet 8, polyurethane film 9 is arranged between cloth sheet 8 and the forefoot, be provided with cloth sheet 10 in the bottom surface of heel position, polyurethane film 11 is arranged between cloth sheet 10 and the heel, inner face at the forefoot position is provided with some cylinder shape grooves 12, is provided with some cylinder shape grooves 13 at the inner face face of heel position.

Though the present invention discloses as above with a preferred embodiment, is not in order to limit scope of the invention process.Any those of ordinary skill in the art, promptly every when doing a little improvement in not departing from the scope of the present invention according to the equal improvement that the present invention did, should be scope of the present invention and contain.
