Abstract
A disclosed novel welt-sewing and leather shoe injection technology comprises the following steps: (1) sleeving a mold of an injection machine with a leather shoe subjected to welt sewing; (2) finishing shaping of PU or TPU mid-sole and undersole in the injection mold; and (3) realizing the connection of the mid-sole with the welt, bonding area and outsole. By employing the above technical scheme, the advantages comprise that the novel welt-sewing and injection sole preparation technology mainly comprises the processes of lasting, welt sewing (exterior line sewing), glue spraying, outsole paving, injection, last discharging, decoration and the like. Leather shoes prepared by employing the technology provided by the invention are salubrious in upper surface, clean in undersole, clear in seam allowance and beautiful in appearance. Also the technology is simple, and the leather shoes are light in weight, good in permeability, beautiful in undersole appearance, various in patterns and kinds, and belong to an upgraded and updated product.
Description
Technical field
The invention belongs to shoe-making field, relate in particular to a kind of seam and along bar, inject the new production technology of leather shoes.
Background technology
The solid special technique of tradition mainly completes: the shoe last or hat block～seam that stretches tight is along the bar～fluffing～brush coating～sticky middle end～seam outside line～brush coating, the large end～operations such as modification of the end～pressing～sand in gluing.Complex process, the leather shoes of making are heavier, and gas permeability is poor, and outward appearance of the large end is crude.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency provides a kind of new groove part to inject leather shoes new technology along bar, and technique is simple, lightweight, good permeability, and appearance looks elegant of the large end, designs and varieties are various.
For achieving the above object, the present invention is by the following technical solutions:
A kind of new groove part injects leather shoes new technology along bar, comprise the following steps: (1) is enclosed within leather shoes seam on the mould of injector after bar, (2) in injection molding, complete the moulding at the end, the large end in injection PU or TPU, (3) realize in the end with along bar, help connecting of pin, outer bottom.
Above-mentioned new groove part injects leather shoes new technology along bar, described step (1) by leather shoes seams along stretching tight during shoe last or hat block before bar, side pin want bonding firmly, seam is during along bar, apart from limit uniformity.
Above-mentioned new groove part injects leather shoes new technology along bar: the molding procedure that step (2) completes the end in injection PU or TPU, the large end in injection molding comprises glue spraying, paving outer bottom, injects and goes out four steps of shoe last or hat block.
Above-mentioned new groove part injects leather shoes new technology along bar, and described glue spraying is along bar and side pin glue spraying everywhere, and glue spraying evenly puts in place, paving outer bottom after glue spraying completes; Injection is that side pin and injection molding after cover shoe last or hat block are closed to limit mould, injection, and 15～17 seconds control times, pressure 7bra, 50 ± 5 ℃ of temperature, complete injection, after injection, go out shoe last or hat block.
Adopt technique scheme, the present invention is by following advantage: this kind of Novel leather shoe seam injects bottom technique processed along bar, mainly completes: the shoe last or hat block～seam that stretches tight is along bar (seam outside line)～glue spraying～paving outer bottom～inject～go out shoe last or hat block～operations such as modification.The leather shoes upper that the present invention makes is salubrious, and the large end is clean, rim of the mouth is clear, handsome in appearance.And technique of the present invention is simple, lightweight, good permeability, appearance looks elegant of the large end, designs and varieties are various, are upgraded products.
The specific embodiment
New groove part injects a leather shoes new technology along bar, comprises the following steps: (1) by leather shoes seams along stretching tight during shoe last or hat block before bar, side pin want bonding firmly, seam is during along bar, apart from limit uniformity.By seam along the side footmuff after bar on the mould of injector, (2) in injection molding, complete the moulding at the end in injection PU or TPU, the large end, the molding procedure that completes the end in injection PU or TPU, the large end in injection molding comprises glue spraying, paving outer bottom, injects and goes out four steps of shoe last or hat block.(3) realize in the end with along bar, help connecting of pin, outer bottom.
Glue spraying of the present invention is along bar and side pin glue spraying everywhere, and glue spraying evenly puts in place, paving outer bottom after glue spraying completes; Injection is that side pin and injection molding after cover shoe last or hat block are closed to limit mould, injection, and 15～17 seconds control times, pressure 7bra, 50 ± 5 ℃ of temperature, complete injection, after injection, go out shoe last or hat block.
Claims (4)
1. a new groove part injects leather shoes new technology along bar, comprise the following steps: (1) is enclosed within leather shoes seam on the mould of injector after bar, (2) in injection molding, complete the moulding at the end, the large end in injection PU or TPU, (3) realize in the end with along bar, help connecting of pin, outer bottom.
2. new groove part according to claim 1 injects leather shoes new technology along bar, it is characterized in that: described step (1) by leather shoes seams along stretching tight during shoe last or hat block before bar, side pin want bonding firmly, seam is during along bar, apart from limit uniformity.
3. new groove part according to claim 1 injects leather shoes new technology along bar, it is characterized in that: the molding procedure that step (2) completes the end in injection PU or TPU, the large end in injection molding comprises glue spraying, paving outer bottom, injects and go out four steps of shoe last or hat block.
4. new groove part according to claim 3 injects leather shoes new technology along bar, it is characterized in that: described glue spraying is along bar and side pin glue spraying everywhere, and glue spraying evenly puts in place, paving outer bottom after glue spraying completes; Injection is that side pin and injection molding after cover shoe last or hat block are closed to limit mould, injection, and 15～17 seconds control times, pressure 7bra, 50 ± 5 ℃ of temperature, complete injection, after injection, go out shoe last or hat block.
