Detailed description of the invention
In order to the technical solution of the utility model is explained further, it is described in detail below in conjunction with the accompanying drawings.
Referring to figs. 1 through Fig. 2, a kind of bullet particle sole of PU form, including sole body, half sole, arch and the heel of sole body correspondence human body is respectively equipped with front metacarpus, arch portion and heel portion, and described sole body includes the substrate 10 by PU form and the bullet particle 20 being laid in substrate 10.In actual production, PU solution and bullet particle 20 are placed in the die cavity of lower mold, mold is covered in lower mold, heating makes PU solution foaming be molded into have the sole body corresponding with human foot, the sole body made in this way, playing particle 20 can be laid in equably in substrate 10, processing method is simple simultaneously, it is possible to the manufacture efficiency of improving product.
As a kind of preferred embodiment of the present utility model, described bullet particle 20 is TPU bullet particle.The advantage that TPU has environmental protection and good springiness so that sole of the present utility model has preferably elastic and environmental-protecting performance.
As a kind of preferred embodiment of the present utility model, the corresponding described front metacarpus of the lower surface 12 of described substrate 10 is provided with the first supporting layer 30.As a kind of preferred embodiment of the present utility model, the corresponding described heel portion of lower surface 12 of described substrate 10 is provided with the second supporting layer 40.As a kind of preferred embodiment of the present utility model, the lower surface of described substrate 10 is provided with the 3rd supporting layer 50, and the 3rd supporting layer 50 is arranged between described first supporting layer 30 and described second supporting layer 40.First supporting layer the 30, second supporting layer 40 and the 3rd supporting layer 50 are in the way of hot pressing laminating or the mode pasted of adhesive is connected to the lower surface 11 of substrate 10.
