Description
Technical field
The utility model relates to shoe-making dies and patch bottom method and technology field more particularly to one kind spikes bottom injection mold
Tool.
Background technique
Shoes mould typically refers to the mold of the footwear such as sport footwear, beach shoes, slippers, rubber overshoes, wherein based on sport footwear.Mould
Tool refers in industrial production to be molded, be blow molded, squeeze out, die casting or the methods of forging and forming, smelting, punching press, stretching obtain institute
Need the various moulds and tool of product.
The trend of sport footwear, which has been more than, payes attention to shape design and popularity, and function and comfort also have become emphasis
One of.The especially part of sole, major famous brand sport footwear manufacturer spare no effort to put into the work of innovation one after another.Sole
Therefore mould factory faces the variation of shoe style free form surface, the product life cycle shortens, and promotes the demands such as quality；It and is that can reach city
Field demand, certainly will will be substantially improved in the design and manufacturing technology of die for shoe-sole.
Sports shoes bottom materials generally have RB (rubber), RS (blown rubber), TPR (thermoplastic elastomer (TPE)), EVA (ethylene-
Acetate ethylene copolymer, including IMEVA project one-pass molding EVA and CMEVA traditional secondary form EVA), PU, TR, BR, TPU,
PVC etc..Different motion shoes sole needs to design different die for shoe-sole because of its material difference, while using different patch bottom sides
Method, wherein the mold of several main materials such as RB, EVA, TPR is most widely used.
Such as the Chinese utility model patent of 106739055 A of Publication No. CN discloses a kind of rubber soles injection mold
Tool and injection moulding method, injection molding include the upper mold that can successively mold, middle mould and lower die, and lower die, which is provided with, can be arranged upper of a shoe
