Description
Technical field
The utility model relates to footwear and manufactures field, is specifically related to a kind of PU elastic environmental-protection sole and makes mould.
Background technology
The applicant has applied for a kind of resistant to hydrolysis PU elastic environmental-protection sole (201220511599.1) patent in 2012, it comprises the large end and PU foaming layer, and the described large end is provided with container cavity, and described PU foaming layer is positioned at container cavity of the large end; It also comprises the shoe-pad being positioned in PU foaming layer, and described shoe-pad is provided with several ventilative through holes.Although that this utility model has is wear-resisting, endurable, environmental protection, flexible, not yielding, light weight, deodorizing, the advantages such as treatment pedopathy, but still there is following problem: when PU hardness is softer in container cavity of the large end, in container cavity, easily swell in bottom minute, wrinkling connects, more easily fracture, produces quality problems; Sole color is not abundant; Container cavity of the large end easily shrinks or elongates when producing, and causes container cavity to mate with PU injection mold, when producing, is easily out of shape.
Utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of PU elastic environmental-protection sole, has the advantages such as light weight environmental protection, flexible, easy fracture wrinkle does not connect, color is abundant, not yielding.
Another object of the present utility model is to provide a kind of making mould of PU elastic environmental-protection sole.
For addressing the above problem, the technical scheme that the utility model adopts is as follows:
A PU elastic environmental-protection sole, it comprises the large end and the middle end; The described large end, is laminar, caves in downwards to form a plurality of depressed parts or empty and form hollow container cavity in the large end; The described middle end is PU foaming layer, is at least provided with a bolster at middle the end, is also provided with passage at middle the end; The described middle end, fits in completely at large the end.
Preferably, the material at the described large end is a kind of in TR, TPU, TPE, PVC, TPR, EVA, PU, rubber.
Preferably, the thickness at the described large end is 1.5-2.5mm, and hardness is 40-50 shore hardness.
Preferably, the thickness at the position easy to wear at the described large end is 3-5mm.
Preferably, described depressed part comprises groove and shrinkage pool, and described groove comprises the first groove and the second groove, and the first groove is positioned at the sole middle part at the described large end, and the second groove is positioned at the heel middle part at the described large end; Described shrinkage pool is uniformly distributed along the periphery of the first groove, the second groove.
A kind of making mould of PU elastic environmental-protection sole, it comprises mould upper cover, mould middle cover and mould bottom, mould bottom is provided with first cavity matching with the large end, described mould middle cover is penetrated with and matches with exterior contour of the large end and surrounding inwall is provided with the second cavity of decorative pattern or pattern, covers and be provided with the briquetting matching with the second cavity shape on described mould; Mould bottom one end is provided with articulated section, and one end of mould middle cover is hinged on one end of the first cavity top mould bottom, and mould upper cover is hinged on one end of the mould middle cover of the second cavity top.
Preferably, on described briquetting, be also provided with several projections.
Preferably, described mould upper cover, mould middle cover, mould bottom are equipped with handle.
Compared to existing technology, the beneficial effects of the utility model are: PU elastic environmental-protection sole of the present utility model has the advantages such as light weight environmental protection, flexible, easy fracture wrinkle does not connect, color is abundant, not yielding.Not only than having reduced rubber consumption environmental protection more, having solved that wrinkle connects, expansion and phenomenon of rupture, and can accomplish the middle end and different colours of the large end, color is abundanter.Due to the formation depressed part that caves in downwards of the large end, it is thicker that the therefore large end, can do, and makes middle end PU and water touch opportunity less, greatly reduce the hydrolysis chance of PU while wearing, therefore owing to exposing with rubber consumption littlely in the middle end, can not affect the degraded of shoes after discarded, practical environmental protection.Because laminar large base is along thinner, during production, to pull out mould comparatively easy at the large end, also easily controls its shrinkage rates, solved the large end while producing because elongating and shrinking the problem that cannot mate with PU injection mold.
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
