Abstract

The utility model relates to a shoe mould device which comprises a middle mould and a lower mould, wherein a plurality of small mould cavities are arranged in a mould cavity of the lower mould, and spacing parts are formed between every two small mould cavities; the middle mould is provided with a middle mould block corresponding to a shoe-shaped mould cavity of the lower mould, the middle mould is concavely provided with a groove, and a soft buffer block larger than the ranges of the small mould cavities is inlaid and fixed in the groove. The impact force of press fit can be instantly and effectively reduced by the shoe mould device, the damage of the lower mould is avoided and the service life of the lower mould is prolonged.

Description

A kind of footwear die device

The utility model is about a kind of footwear die device.

More popular for the design of pursuing shoes at present, change more various, the design of a lot of soles is to have the different layers look, or the color lump section of sole is identical, the method for making of sole like that need cooperate have on, in, the footwear mould of counterdie, as shown in Figure 5, middle mould 50 is independently, can corresponding sole system establish kenel and overpay, have two kinds of color block areas such as sole, therefore in the footwear pattern cave of counterdie 40, be categorized into the little die cavity 41 of two part color lumps, 43, when wherein a kind of color color lump of moulding, cooperate this to be set as the middle mould 50 of corresponding little die cavity 41 positions earlier, therefore should place on the counterdie 40 by middle mould 50, and by little die cavity 41 injected plastics 60 of material road towards desired location, after the material filling, mould 50 in the extraction, directly press down patrix 30 in counterdie 40 and pressurized, heated, reach the color lump of moulding predetermined color on the little die cavity 41 of counterdie 40, then, change in another pair mould 50 again to penetrate the color of little die cavity 43.

But the design of mould 50 is unsatisfactory in aforementioned, and reason is as back:

1, greatest problem is to cause the problem of counterdie 40 easy damaged; Because middle mould 50 is the metallic hard plastid, counterdie 40 also is the metallic hard plastid, and central mould 50 is pressed on the impact of counterdie 40, is the antagonism of duromer and duromer, so counterdie 40 is easily because of injuries such as this bump are worn;

Aforementioned bump produce maximum position be between each little die cavity 41,43 every portion 45, the position is close each other owing to little die cavity 41,43, every portion 45 even have only 1～1.5mm, therefore under the situation a little less than the thin thickness, aforementioned impact often causes 45 fractures every portion, in case fracture, not attractive in appearance owing to take that plastics between each little die cavity 41,43 can interpenetrate into account, so must give up whole counterdie 40, cause the quick shortcoming that shortens in service life of counterdie 40, increase the puzzlement of reopening die cost, operation.

2, because middle mould 50 is big with the mutual strike note of duromer of counterdie 40, cause the noise of working environment.

3, middle mould 50 is aluminum cast bodies with counterdie 40 overwhelming majority, without heat treatment is arranged, so aforesaid bump problem is easy to occur unfilled corner, slight crack so that material filling by problems such as this slight crack seepages.

The purpose of this utility model is to be to provide a kind of footwear die device, can subdue the impact of this pressing immediately effectively, avoids the counterdie damage, prolongs the service life of counterdie.

In order to achieve the above object, the utility model provides a kind of footwear die device, it comprises patrix, middle mould and counterdie, be provided with most little die cavitys in the die cavity of this counterdie, be formed with every portion between this each little die cavity, should in mould shoe-shaped die cavity that should counterdie is provided with middle module, it is characterized in that: module is concaved with groove in this, is embedded to be fixed with one greater than this little die cavity scope and soft buffer stopper in this groove.

According to last explanation, the utility model mainly is to improve known shortcoming, and its characteristics are as back:

1, because the middle calligraphy or painting model body of buffer stopper hardness is low, and have suitable elasticity, thus when central mould and counterdie pressing, not can because of this pressing impact under be molded as and times close damage, guarantee that effectively increase the service life of counterdie.

Even if with the passing of time the buffer stopper of 2 middle moulds damages because of using, as long as take out buffer stopper, change new buffer stopper again and get final product, can grow the service life of mould in protecting.

3,,, reduce noise so can absorb the bump sound that is pressed on counterdie because middle mould is provided with buffer stopper.

4, middle mould is provided with buffer stopper, so can not clash into every portion, can not guarantee that the material filling boundary of variant color color lump is clear and definite to produce any harmful effect every portion, and the boundary of different colorants is easily cut off, and ensures the quality attractive in appearance that sole is made.

For enabling further to understand architectural feature of the present utility model and practical effect, cooperate graphic detailed description as back with preferred embodiment hereinafter described now:

Brief description of drawings:

Fig. 1 is an element exploded perspective view of the present utility model.

Fig. 2 is an assembled sectional view of the present utility model.

Fig. 3 be of the present utility model in the molded assembled sectional view of making.

Fig. 4 is molded as in of the present utility model and the element exploded view that allows buffer stopper tell.

Fig. 5 is the assembled sectional view of conventional footwear mould.

See also Fig. 1, shown in Figure 2, the utility model mainly is middle mould 10 relative counterdie 40 little die cavitys 41 positions, middle module 11 in middle mould 10 correspondences is concaved with groove 13, embedding is fixed with a buffer stopper 15 greater than little die cavity 41 scopes in groove 13, this buffer stopper 15 for nonmetallic plastics, rubber etc. slightly the flexible material of tool make;

Therefore as shown in Figure 2, in the middle of during mould 10 pressing counterdies 40, because the position of corresponding little die cavity 41, and contain every portion 45 positions, all be embedded with the buffer stopper 15 of elastic buffer, so mould 10 strikes the impulsive force of counterdie 40 every portion 45 in reducing, avoid making counterdie 40 whole puzzlements of scrapping every portion's 45 fractures.

As shown in Figs. 3-4, the binding process of middle mould 10 and buffer stopper 15, wherein cooperate patrix 30 and counterdie 40 earlier, the little die cavity 41 in precalculated position pours into rubber relatively on counterdie 40, cooperate patrix 30 matched moulds again, the heating extrusion forming, promptly taken out buffer stopper 15, make buffer stopper 15 independently, the decorative pattern of buffer stopper 15 corresponding little die cavitys 41 also can be formed with corresponding lines (as Fig. 4) and transfer to the pincers worker mode again and grind off decorative pattern, to guarantee that with middle module 11 surface morphology be concordant, again buffer stopper 15 sticking establishing in the groove 13 that is glued at middle mould 10 are fixed, promptly make middle mould 10 with buffer stopper 15.

Claims

1, a kind of footwear die device, it comprises patrix, middle mould and counterdie, be provided with most little die cavitys in the die cavity of this counterdie, be formed with every portion between this each little die cavity, should in mould shoe-shaped die cavity that should counterdie is provided with middle module, it is characterized in that: module is concaved with groove in this, is embedded to be fixed with one greater than this little die cavity scope and soft buffer stopper in this groove.
