Description

Integrated pair of hardness sole of homogenous material

The utility model is about a kind of sole, refers to integrated pair of hardness sole of a kind of homogenous material especially.

Because modern's standard of living order gradually improves, material requirements for the shoes that all need wear every day is also more and more high, and utilize the sole of foaming jetting mold system the most common, the variation very of at present general being seen ejaculation footwear sole construction, but, the finished product of footwear sole construction whether the preferable comfort of tool, tool just becomes the problem that the producer and user attach great importance to than the long life.

Traditional footwear sole construction sees also shown in Figure 1ly, is the die cavity 12 shot foamed moulding footwear sole constructions that the counterdie 11 by an ejection formation patrix 10 and corresponding patrix 10 combines; The sole that this kind commonly used is being sold on the market, is being used for a long time, but this kind design still has its weak point on practicality, makes its effect unclear, and tracing it to its cause is to be:

One, the optimal mode of general sole is that all side materials of sole are hard, internal material is soft, can protect user's foot because of all side materials, the softer user foot that then can make of internal material is comfortable, but it is identical to commonly use the hardness that penetrates after the footwear sole construction shooting foaming is finished, if when taking higher density that adopt service life, high hardness material into account, then need establish many through holes, so that the sole internal material is more soft in inside system;

They are two years old, therefore planting the material of commonly using footwear sole construction penetrates to this die cavity 12 from ejaculator 13, for ask material and die cavity 12 mutually urgent (because of material and die cavity 12 mutually urgent after, trickle decorative pattern, the shape of this die cavity 12 could present fully), commonly use the ejaculator 13 of sole jetting mold and all can inject fuller material, foaming goes out footwear sole construction again, does not amplify so the finished product of commonly using fills the foaming of part usually, but form the too high sole of density, and make sole overweight, really up to the mark.

The purpose of this utility model is to provide a kind of homogenous material integrated pair of hardness sole, advantage such as that this sole has is comfortable and easy to wear, wear-resisting, crashworthiness and weight are lighter.

The technical solution of the utility model is to provide a kind of homogenous material integrated pair of hardness sole, it is characterized in that:

This sole comprises the integrated body of homogenous material, and forms a plurality of low density structures district in the body, and all the other zones then are the high density structures district.

Integrated pair of hardness sole of described homogenous material is characterized in that: the body peripheral edge margin of this sole and below base surface area are the high density structures district.

Integrated pair of hardness sole of described homogenous material is characterized in that: the low density structures district is the foot-operated position of corresponding wearer in the body of this sole.

Integrated pair of hardness sole of described homogenous material is characterized in that: the low density structures district that this sole forms can have different density separately.

In sum, the utility model case is the mould that can change the die cavity accommodation space according to predetermined design with a group, has the footwear sole construction of different densities with each position of the one-body molded ejaculation of homogenous material; The utilization said structure, the hardness that the utility model can be stepped on the user low density structures district of stepping on reduces, and obtains preferable comfort, more can need are wear-resisting, the high density structures district material hardness at the position of crashworthiness improves, and makes extend the service life of sole.

Relevant the utility model is to reach technological means and the effect thereof that above-mentioned purpose adopts, but enumerates a preferable embodiment now and cooperate graphic detailed description as back:

The explanation of accompanying drawing drawing:

Fig. 1 commonly uses the cutaway view that sole penetrates operation.

Fig. 2 is embodiment sole product figure of the present utility model.

Fig. 3 is that embodiment of the present utility model penetrates flow diagram.

Fig. 4 is that cardon is made in the die displacement in the embodiment of the present utility model.

Fig. 5 is embodiment material foaming process figure of the present utility model.

Fig. 6 is an embodiment sole cutaway view of the present utility model.

Please consult shown in Fig. 2,3,6 earlier, integrated pair of hardness sole of homogenous material of the present utility model, this sole comprises the integrated body 90 of homogenous material, the in good time displacement of

utilization patrix

30 and 50 interior dies 43 of counterdie, and make the same material foaming density in sole die cavity 51 spaces change, make to form a plurality of low density structures district 93 in the body 90, all the other zones then are high density structures district 94.

Several regions in this footwear sole construction body 90 is foaming-formed to go out the lower low density structures district 93 of density, and the periphery 92 of this footwear sole construction body 90 and bottom surface, below 91 then are with the same material of the higher density foaming-formed high density structures district 94 that forms simultaneously.

Following explanation preferable manufacture of the present utility model, manufacture of the present utility model can be pushed away with a start by a top board 20, a patrix 30, two acting devices 40, counterdie 50, a workbench 60 to be made common cooperation of member such as cylinder 70:

Please cooperate consult shown in Figure 3, when start pushes away cylinder 70 and passes through these workbench 60 table tops and promote to move on this patrix 30 and the counterdie 50, the spring 42 of this acting device 40 is gone into these patrix 30 scalariforms by the head end 44 downward ejections of operating bar 41 and is buried in the groove, should then outwards move (in the sole die cavity 51 of counterdie 50, moving) by interior die 43 by the accommodation space 31 of this patrix 30, make sole die cavity 51 spaces diminish, just compeled to squeeze by interior die 43 and penetrate the emitted small quantity of material of facility, and make as yet the not urgent sole die cavity 51 of material of foaming, can present the trickle decorative pattern of tool in the sole die cavity 51 fully, the periphery 92 of shape and bottom surface, below 91, and become high density structures district 94;

Please cooperate consult shown in Figure 4, after treating periphery 92 and bottom surface, below 91 and sole die cavity 51 mutually urgent one-tenth high density structures districts 94, this start pushes away cylinder 70 just can make this top board 20 no longer compress this operating bar 41

head ends

44,43 of dies are withdrawn in the accommodation space 31 again, these sole die cavity 51 spaces are amplified and space 80, see also shown in Figure 5, this penetrates the partly not fixed-type as yet small quantity of material of facility and flows to this space 80, and the foaming that begins to fill part, because die cavity 51 all sides are cooled off already, so all side density of finished product of the present utility model is higher, and the expanded material of central authorities can fill the lower zone of formation density after 80s, this space, this zone just forms low density structures district 93, and this low density structures district 93 cooperates the high density structures district 94 of periphery 92 and bottom surface, below 91 to become complete footwear sole construction body 90.

Be worth adding again emphasize be, see also shown in Figure 6, because the low density structures district 93 later expanded materials that charge into of the utility model footwear sole construction body 90, so a small amount of as yet not the expanded material of moulding can have bigger foaming space (space adds space 80 originally), so density meeting less (material is softer) of low density structures district 93 foamings, and originally compeled to squeeze in the expanded material of the periphery 92 of sole die cavity 51 walls and bottom surface, below 91 by interior die 43 because the time of foaming cooled and solidified shorter, density of material is big, so the material hardness of footwear sole construction periphery 92 and bottom surface, below 91 is harder; The utilization said structure, the utility model can be arranged on the user with footwear sole construction body 90 several regional low density structures districts 93 and step on the position of stepping on, to obtain preferable comfort, utilize the high density structures district 94 of periphery 92 and bottom surface, below 91 to make and part material hardness wear-resisting, crashworthiness to improve again, make extend service life of the present utility model; So the utility model is a kind ofly can produce the integrated pair of hardness sole of homogenous material in preferable comfort and service life by different hardness really.
