Abstract

The present invention relates to an injection technology for stitching a sole, which comprises the following steps: an upper of which a vamp and a lining are stitched up is stitched onto a cloth sole, sheathed with a shoe tree and lowered into a shoe mould; the shoe tree is lifted to certain height by a homemade chucking appliance; the shoe tree is lowered after side moulds are closed; a bottom mould is pushed by a foaming cylinder at the station before material injection, the sole is ejected to the station of injection, and the bottom mould is lowered by the foaming cylinder; a space is formed between the bottom mould and the sole, and then, materials such as plastics, rubber, SPS, etc., are injected into the space and attached to the stitched sole by hot fluidized liquid to form a protecting layer of the sole. The present invention has the advantages of durability, abrasion and breaking resistance, and comfortable wearing.

Description

Stitch the injection technique at the end of stitching the sole to the upper

The present invention relates to shoe-making field, the stitch the sole to the upper injection technique at the end of a kind of seam.

At present, in shoe-making industry, to stitch the sole to the upper be after the shoe lining vamp is made, to be stitched together with plastics, rubber, cloth sole to seam again, after adopt for people comfortable and easy to wearly, added one deck cloth matter, cotton, yarn matter sock in plastic sole and upper of a shoe centre.Like this, when people put on this footwear, because cloth matter sole lining is not wear-resisting, be easy to wearing and tearing, sole directly contacts plastic sole, and sweaty feet people have especially suffered all hardship; In addition, on this sole face of making, suture can expose, and is easy to wearing and tearing, causes footwear not endurable; Moreover this type of sole is also thinner, wears uncomfortable.

The purpose of this invention is to provide the stitch the sole to the upper injection technique at the end of a kind of seam, after it made upper of a shoe and cloth sole, injection of plastic, rubber, SPS etc. on cloth matter sole made it endurable again, and folding, wear-resisting is comfortable and easy to wear.

For achieving the above object, the present invention adopts following technical scheme:

The stitch the sole to the upper injection technique at the end of described seam: upper of a shoe and cloth matter sole seam stitch the sole to the upper after vamp and shoe lining made are good; be enclosed within upper of a shoe of making and sole on the shoe tree together again; fall into shoe mould; with homemade jig shoe tree is mentioned certain altitude again; with two limit moulds altogether; clamp the cloth sole; shoe last or hat block again falls behind the matched moulds; take off jig; at the last station of material feeding, utilize the foaming cylinder that bed die is boosted, flat seam stitch the sole to the upper cloth sole top to injection station; the foaming cylinder falls bed die again; at this moment, form the space between bed die and the cloth sole, carry out material feeding then; adopt the plastics of hot-fluidization; rubber; thawing liquid such as SPS stick to and stitch at the end of stitching the sole to the upper, and form plastics; the protective layer of rubber or SPS.

The present invention has following superiority:

After the end adopted upper of a shoe and cloth matter sole seam stitch the sole to the upper good because the present invention seam is stitched the sole to the upper, stitching injection of plastic, rubber, SPS etc. on the good cloth matter sole of stitch the sole to the upper again, so just strengthening the wearability of cloth matter sole, fold resistance can prolong and stitch wearing the life-span of stitch the sole to the upper cloth shoes.

Because seam is stitched the sole to the upper the end be with footwear nation and cloth sole stitch stitch the sole to the upper good after again injection of plastic, rubber, SPS etc. add protective layer, cloth matter sole directly contacts with people's foot bottom, people are comfortable and easy to wear, especially those suffered from the people of beriberi, pin sweat, reduce its misery.
