Abstract
The invention provides an upper and sole brush-coating-free forming technology. The upper and sole brush-coating-free forming technology comprises the following specific operation steps that firstly, an insole is roughed and put into a mold, then a layer of lint with the bottom face covered with a hot-melting glue film is laid and integrally formed, and a formed sole is obtained; secondly, the formed sole is put into a mold cavity; thirdly, polyurethane elastomer rubber is injected into an inner core concave cavity of the sole; fourthly, an upper sleeved with a last is put in, cooled and shaped; fifthly, a scrap is trimmed off, and a finished shoe is obtained. The upper and sole brush-coating-free forming technology can solve the existing problems of complex procedures, a large labor amount, a long process and a low yield due to brush coating binding, and can also avoid potential safety hazards, caused by using chemical glue liquid, of a production environment.
Description
[technical field]
The invention belongs to technical field of shoe making is and in particular to brush coating moulding process is exempted from a kind of side bottom.
[background technology]
In shoe-making field, during traditional shoemaking, the molding of the sole (generally referred to as middle bottom) of shoes upper and bottom
I.e. side bottom molding generally all relies on brush coating attaching process completing, this technique process is complicated, the amount of labour used is big, long flow path,
Yield poorly, and further relate to glue liquid medicine, there is Environmental security hidden danger.
Therefore, a kind of new side bottom moulding process is developed in the urgent expectation of practitioner, can solve the problem that existing employing brush coating
The problems of laminating, and it can be avoided that the potential safety hazard of production environment.
[content of the invention]
The technical problem to be solved is to provide a kind of side bottom to exempt from brush coating moulding process, can not only solve existing
Have because the complex procedures existing using brush coating laminating, the amount of labour used are big, long flow path and the problem yielding poorly, and it can be avoided that
Lead to the potential safety hazard of production environment because of the use of glue liquid medicine.
The present invention is to solve above-mentioned technical problem by the following technical programs: a kind of side exempts from brush coating moulding process in bottom, its
Including following concrete operation step:
(1), middle bottom is beaten slightly, and put in mould, layer overlay bottom surface is covered with the flannelette of hot melt adhesive film and becomes together afterwards
Type, then obtain the sole after molding；
(2), the sole after molding is put into mold well；
(3), polyurethane rubber is injected in the interior core cavity of sole；
(4), it is then placed in covering the upper extruding cooling and shaping of last carving.
Further, in described step (1), the top edge at middle bottom swells formation one upwards in order to accept excessive polyurethane
The scrap (bridge) of rubber；And this technique also includes operating as follows: prune away behind (5), cooling and shaping scrap (bridge) and unnecessary the gathering overflowed
Urethane rubber gets product footwear.
A kind of side of the present invention exempts from bottom having the beneficial effects that of brush coating moulding process:
By laying be covered with hot melt adhesive film flannelette, injection polyurethane rubber (pu) cooperate so that upper and sole
Well molding, without using brush coating operation, can not only solve existing because of the complex procedures existing using brush coating laminating, use
Work amount is big, long flow path and the problem yielding poorly, and it can be avoided that because glue liquid medicine using and lead to production environment safety hidden
Suffer from.
[specific embodiment]
A kind of side of the present invention exempts from brush coating moulding process in bottom, and its flow process includes: Sole moulding → injection pu → upper inserts →
Cooling shaping.
This technique concrete operations is as follows: middle bottom is beaten slightly, and puts in mould, layer overlay bottom surface is covered with PUR afterwards
Molding then completes Sole moulding operation to the flannelette of film together, obtains final product the sole after molding；Then the sole after molding is put into mould
Tool cave；Then polyurethane rubber (i.e. pu) is injected in the interior core cavity of sole；It is then placed in covering the upper extruding cooling of last carving
Sizing.
During die operation, mould temperature: heating-up temperature is 170-175 degree, chilling temperature is 20-25 degree, clamp time: heating
The 420-600 second, cooling the 450-620 second, that is, mould from room temperature through 170-175 degree sizing board heating the 420-600 second after turn
Enter water-cooled shaping board to be cooled down, the cooling 450-620 second is to room temperature, alternately and repeatedly operation；And die pressure 120kg/cm2.
Wherein, mold well is in order to fixed soles；Polyurethane rubber is a kind of adhesive of environment-friendly type, injects polyurethane
Rubber is to be carried out in the form of the cast of equipment gun barrel；Hot melt adhesive film is also to play the gluing effect of environmental protection, and its effect is
Allow flannelette is stronger to be bonded on sole.The concrete operations spreading flannelette on middle bottom are: by the matte of flannelette upward, the bottom of flannelette
Face (i.e. non-matte) is covered with hot melt adhesive film, and the bottom surface laminating of flannelette is laid on middle bottom；Laying flannelette is thick for bottom in increasing
Rough degree and microcellular structure, thus contribute to the gluing combination at middle bottom and upper；In addition, because follow-up upper and sole are extruded to shape
When polyurethane rubber excessive phenomenon occurs, in order to accept this partly excessive polyurethane rubber out, in the top edge at middle bottom
Protuberance forms a scrap (bridge) upwards, and for 0.3mm, width in 10mm, it can not only accept excessive polyurethane out to scrap (bridge) thickness
Rubber, and the positioning of flannelette and upper can be more convenient；When being provided with described scrap (bridge) on central bottom, then after cooling shaping operation
Also need to carry out shoes finishing process, specifically, prune away scrap (bridge) after cooling and shaping and overflow the unnecessary polyurethane rubber of coming
Get product footwear.
To sum up, the present invention pass through laying be covered with hot melt adhesive film flannelette, injection pu cooperate so that upper and sole very
Good molding, without using brush coating operation, can not only solve existing because of the complex procedures existing using brush coating laminating, recruitment
Measure big, long flow path and the problem yielding poorly, that is, being capable of improve production efficiency, reduction cost of labor；And it can be avoided that because of glue medicine
Water using and lead to the potential safety hazard of production environment.
