On the other hand, PU is as a kind of thermosetting plastics, and it also is widely used in various fields, and the chemical name of PU is a polyurethane resin, and English name is Polyurethane Resin.It is after the process cure process, can make rigid foam, it has high compressive strength, good heat resistance and dimensional stability, and has an air permeability and good, as see that the patent No. is the Chinese invention patent specification of ZL 92115394.5, it discloses a kind of method for preparing the hard polyurethane foam plastic of perforate.In addition, PU can be directly by the technology mode processing of injection moulding, and it can process various moulding with different demands like this, and its this specific character also makes many shoemaking merchants adopt it as the material of producing shoe-pad or sole.Yet the price of PU is expensive than EVA, directly adopts the PU material, causes the cost of product to improve greatly, makes it the market competitiveness and descends.
Summary of the invention:
The objective of the invention is to overcome the deficiency of present like product, provide a kind of economic, practical, adopt the preparation method at the end in the footwear of different materials and PU material bond material.
The art scheme of skill that the present invention adopts is: at first make the middle part, next is that the middle part that will make is positioned over the central authorities that make bottom die in the footwear, with injection molding way the PU material is injected in the peripheral die space in middle part, form outer rim, outer rim and middle part are fixed as one in the injection moulding mode; The middle end that to make at last, is by taking out in the mould.
Above-mentioned middle part is to make after handling through foaming through the EVA material of excision forming.
Above-mentioned middle part is that the coir fibre mattress through the leveling moulding is made through excision forming.
The present invention adopts this method, materials such as EVA, coir fibre mattress and PU material are integrated, be made into the end in the footwear, utilize the middle part of the higher characteristic of the pliability of EVA, coir fibre mattress as the end in the footwear, with comfort and the reinforcement damping effect that improves sport footwear, and can play the effect that reduces cost.Utilize the plasticity of PU simultaneously, the periphery at the end formed outer rim during it was distributed in, and the carrier that is formed at like this on the outer rim can be directly and the outer rim single injection-molded.Even in the shoemaking process, need the centering feather edge to shear or abrasive material in addition, also can directly carry out, this is to have utilized the dimensional stability of PU material good equally, the characteristics that plasticity is strong.
