Abstract
The invention discloses a novel process for manufacturing leather shoes, which comprises the steps of lasting, napping, adhesive brushing, rubber sheet placement in a die cavity, injection molding and vulcanization molding, wherein before the step of lasting, a rubber sheet and a vamp are stitched together by using a stitching thread, and then the steps of lasting, napping, adhesive brushing, rubber sheet placement in a die cavity, injection molding and vulcanization molding are performed. Compared with traditional mould pressing modes, the process disclosed by the invention has the differences that after the step of adhesive brushing is completed, rubber and the vamp are stitched together by using a stitching thread, then the steps of adhesive brushing and vulcanization are performed, the rubber subjected to vulcanization in the die cavity and the rubber of the original stitching thread are fused into a whole, and then through the adhering action of an adhesive, the strength of the stitching thread is increased, therefore, the adhering strength of the vamp and a rubber sole is greatly improved, and through measuring and calculating, the adhering strength can be increased by more than one time. Meanwhile, the appearance quality of products has no change, and the stitching thread can not be seen from the vamp and inside of a shoe, but a stitching thread is just added in the internal structure of the shoe.
Description
Technical field
The invention belongs to shoe-making field, relate in particular to a kind of technique of new making leather shoes.
Background technology
Traditional mold pressing leather shoes technique is put into rubber in the moulding press die cavity after being upper of a shoe fluffing, brush coating, by series of process conditions such as temperature, pressure, makes the vulcanization of rubber, moulding, and vamp is bonded in Jiao Dishang.---fluffing---brush coating---putting film (injection rubber) presses in die cavity-notes---sulfuration that conventional process flow is: shoe last or hat block stretches tight.This technique is widely used in military products, foreign trade, the civilian goods, is one of large technique of four in traditional shoe-making process.Bonding main dependence adhesive at the bottom of this technique upper and the glue bonding has certain limitation.Along with improving constantly of living standards of the people, the variation of material is tending towards variation, because the defective of material itself, bonding often have certain difficulty.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency provides a kind of leather shoes making new technology, by suture face face and rubber is stitched together first, carries out brush coating sulfuration again, has greatly improved the bonding strength at the bottom of upper and the glue.
Purpose of the present invention is achieved through the following technical solutions:
A kind of leather shoes making new technology comprises the shoe last or hat block-fluffing-brush coating that stretches tight-put film in die cavity-notes pressure-sulfidization molding by suture film and upper being stitched together the shoe last or hat block-fluffing-brush coating that stretches tight again-put film in die cavity-notes pressure-sulfidization molding before the shoe last or hat block that stretches tight.
Above-mentioned leather shoes making technique adds the brush coating operation at brush coating again with putting film between the die cavity two-step.
Adopt technique scheme, the present invention has following advantage: be different from the conventional moulded mode of the present invention is stitched together rubber and upper by suture behind the brush coating, carry out again brush coating, sulfuration, rubber after the sulfuration in the die cavity has been fused into one with the rubber of original suture, the adhesive effect by adhesive again, increase again suture intensity, greatly improved the bonding strength at the bottom of upper and the glue, can improve bonding strength more than one times according to measuring and calculating.Simultaneously, any variation does not occur in the product appearance quality, all can not see suture from upper, the inside, has just increased suture in internal structure.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
A kind of leather shoes making new technology as shown in Figure 1, comprise the shoe last or hat block-fluffing-brush coating that stretches tight-put film in die cavity-notes pressure-sulfidization molding, before the shoe last or hat block that stretches tight, by suture film and upper are stitched together the shoe last or hat block-fluffing-brush coating that stretches tight again-put film in die cavity-notes pressure-sulfidization molding.
The present invention adds the brush coating operation at brush coating again with putting film between the die cavity two-step.
Be different from the conventional moulded mode of the present invention is stitched together rubber 3 and upper 1 by suture 2 behind the brush coating, carry out again brush coating, sulfuration, rubber after the sulfuration in the die cavity 4 has been fused into one with the rubber of original suture, the adhesive effect by adhesive again, increased again suture intensity, greatly improve the bonding strength at the bottom of upper and the glue, can improve bonding strength more than one times according to measuring and calculating.Simultaneously, any variation does not occur in the product appearance quality, all can not see suture from upper, the inside, has just increased suture in internal structure.
Claims (2)
1. leather shoes making new technology, comprise the shoe last or hat block-fluffing-brush coating that stretches tight-put film in die cavity-notes pressure-sulfidization molding, it is characterized in that: before the shoe last or hat block that stretches tight, by suture film and upper are stitched together the shoe last or hat block-fluffing-brush coating that stretches tight again-put film in die cavity-notes pressure-sulfidization molding.
2. leather shoes making technique according to claim 1 is characterized in that: add the brush coating operation at brush coating with putting film between the die cavity two-step again.
