Description
Technical field
The invention belongs to footwear and shoe-making process field, specifically refer to a kind of integrated continuous-upper injection shoes of shoes edge item and
Its special purpose shoes mould and preparation method.
Background technique
Shoes are the necessitys of the mankind, and the aesthetic measure of the design of shoes affects approval of the mankind to shoes.Traditional city
The shoes edge item on shoes that cold bonding technique makes on field is sewed or is bonded using after strip material shearing.This work
Skill is due to having the presence such as glue, the problems such as there are easy degumming and the bad feature of environmental protection.
By retrieval, China Patent Publication No. be CN1649721A disclose a kind of sole be molded into upper of a shoe method and
Implement welt used in this method and shoes mould, apply for artificial Ecco Sko A/S, publication date is on August 3rd, 2005.
In the technical solution, it is noted that provide the way of shoes edge item using note shoes are penetrated, and using putting the shoes edge item sheared
Enter continuous-upper injection mold, the technology, such skill are then realized by the method for penetrating the material automatic bonding shoes edge item of note
Although art solves the defect problem of glue gluing than the combined method of traditional shoes edge item, following problems are still remained:
, using this method, the method and step of postposition shoes edge item is not got rid of first, that is to say, that shoes edge item at first point
Still will shoes edge item by cutting by being placed into mold, then naturally bonded with the material for penetrating note to complete, according to
Buying shoes edge item is not got rid of so, is cut along item, the process for being put into mold, is brought a lot of trouble to shoemaking, in addition, after this
The scheme for setting shoes edge item carries out in injection moulding process being well placed shoes edge item, since shoes edge item is generally flexible material,
It itself is easily bent or bends, when so as to cause continuous-upper injection, which is injection molding material in the form of bending and is fixed, and leads
Cause high rejection rate.
Second point, such shoes edge item production, when side mode is combined in left and right first, due to die location, shoes side
The nuance placed along item, causes mold to cause the damage of shoes edge item or upper of a shoe when squeezing shoes edge item, upper of a shoe, this
The defect rate for the shoes that sample is made greatly improves；
Thirdly, the shoes edge production method mentioned according to the patent formula, even if the shoes made are qualified products,
However since the fixation of shoes edge item is bonded naturally by the note material of penetrating of sole, it is that degree of adhesion is inadequate first, is easily deformed
Fall off, secondly because shoes mould is tightly combined together with upper of a shoe so that penetrate note material can not automatically flow into shoes edge item with
The position that upper of a shoe combines, that is to say, that the shoes made by this method, it is natural between its shoes edge item and upper of a shoe
There is a gap, as being exactly degumming, sample has seriously affected the beauty of shoes, and this gap or accumulation dust impurity,
Make to clear up it is constant, after a period of use will be messy, additionally, due to crack presence be easy ponding, then slowly penetrate
Enter upper of a shoe, influences the experience sense of shoes.
4th point, using the production method of above-mentioned Ecco Sko A/S, the post-processing of shoes has to carry out sole
Sanding and polishing, and it is such post-processing often allow sole more it is coarse unsightly, preferably consumer cannot be allowed to receive.
Summary of the invention
The purpose of the invention is to overcome shortcoming and defect of the existing technology, and provide a kind of shoes edge item one
The continuous-upper injection shoes and its special processing equipment and preparation method of change.
As the first aspect of the invention, the present invention provides a kind of shoes edge item integrated continuous-upper injection shoes, skill
Art scheme be include last carving body, upper mold assembly and bed die, the upper mold assembly includes left side mould and the right mould, and bed die is located at
Between left side mould and the right mould, the peripheral position vertical projections of bed die are provided with bed die coaming plate, setting and its mould in upper mold assembly
What chamber communicated penetrate orifice, the left side mould and the right mould transverse shifting between die sinking and mold closed position, institute relative to bed die
The bed die stated is vertically movable between die sinking and mold closed position relative to upper mold assembly；
The lateral projection along position is corresponded in the upper end of its die cavity in the upper mold assembly be provided with shoes edge ring formed
Type top plate, shoes edge annular shaped top plate, which is divided into two parts and respectively corresponds, to be arranged in left side mould and the right mould；
