In order to solve deficiency in the prior art, the utility model provides one kind and is made of a variety of materials and with compound The sole of shoe of structure.

Technical solution adopted by the utility model to solve its technical problems is：

A kind of sole of shoe, including sole body, it is characterised in that：The sole body includes setting gradually from bottom to top There are the bottom of RB materials of interconnection, the top layer of the middle layer of EVA material and PU materials, the middle layer to be internally provided with TPU The support chip of material is additionally provided with vibration damping sheet inside support chip.

The middle layer top surface is equipped with groove body, and groove body edge is equipped with boss, and the support chip main body is located in groove body, props up Blade top edge is equipped with the intermediate plate being located on the boss, and support chip top surface is located in the middle layer top surface.

The support chip top surface, which is equipped in groove body and groove body, is equipped with the vibration damping sheet, and vibration damping sheet top surface is located at the centre In layer top surface.

It is equipped at least one vacancy section in the middle part of the middle layer, the bottom includes being separately positioned on middle layer bottom surface At least two panels of side before and after vacancy section.

The vacancy section is located at the support chip lower part, and support chip bottom surface is equipped with the positioning being located in the vacancy section Block.

A kind of forming method of sole of shoe, which is characterized in that include the following steps：

Step 1: being molded RB bottoms using compress process stempressing, RB materials are put into RB molds, then cloth is placed on RB materials The cloth applied on RB materials is torn it down in die sinking, makes the overlap on RB materials as cloth is pulled off together by the upper surface of material；

Step 2: after RB bottoms are carried out, hot melt adhesive is brushed on RB bottoms top surface, is put in EVA molds；

The secondary forming process that EVA middle layers use makes foaming EVA crude green bodies, then foaming EVA crude green bodies is put in first In EVA molds, by heating cooling and shaping, RB bottoms and EVA middle layers are combined；

Step 3: prefabricated profiled TPU support chips are attached in EVA middle layers, and damping is applied inside TPU support chips Piece；

Step 4: the sole body that step 3 obtains is put into PU molds and using filming technology is vacuumized, is existed first TPU membrane is applied on PU mold bottom dies, pressing plate is pressed in TPU membrane, bed die is made to form a closed space；

Again by for vacuumizing the pipe sleeve used in the valve of bed die, after heating and softening, unlatching vacuumizes TPU membrane Machine, make TPU membrane completely in PU molds sole body and bed die closely fit together, Reperfu- sion PU raw materials at this time, PU top layers are formed by heating cooling and shaping, PU top layers are combined with sole body.

There is sealing strip in the bed die die face.

The utility model has the beneficial effects that：It is reasonable in design, RB, EVA, TPU, vibration-absorptive material, PU materials are all collected In all brought into play in the advantages of one, all material, greatly improve that sole is functional and comfort.

Specific implementation mode

Illustrate that the embodiment of the utility model, those skilled in the art can be by these by particular specific embodiment below Content disclosed by specification understands other advantages and effect of the utility model easily.

According to Fig. 1 to Fig. 8：A kind of sole of shoe, including sole body, the sole body include the bottom of RB materials The top layer 3 of layer 1, the middle layer 2 of EVA material and PU materials, bottom 1, middle layer 2 and top layer 3 are set gradually from bottom to top and phase It connects, bottom 1 two panels and is separately positioned on the front and back side of 2 bottom surface of middle layer respectively, and the middle layer 2 is internally provided with TPU materials The support chip 4 of material is additionally provided with vibration damping sheet 5 inside support chip 4, the sole body by RB, EVA, TPU, vibration-absorptive material, PU materials all Concentrate on one, the advantages of all material all brings into play, greatly improves that sole is functional and comfort.

Material property is specially：

RB materials (rubber) advantage：Wear-resisting, on-slip；

EVA material (ethylene-vinyl acetate copolymer) advantage：Gently, soft；

TPU materials (thermoplastic polyurethane elastomer) advantage：Support, anti-torsion；

Vibration-absorptive material advantage：Using materials such as polyurethane, with shock-absorbing and damage to foot can be reduced；

PU materials (macromolecule polyurethane synthetic material) advantage：It springs back, is environmentally friendly, degradable, soft, light.

Further, 2 top surface of the middle layer is equipped with groove body, and groove body edge is equipped with boss 6,4 main body of the support chip In groove body, 4 top edge of support chip is equipped with the intermediate plate 7 being located on the boss 6, and 4 top surface of support chip is located at the centre In 2 top surface of layer, so that the mounting structure of support chip 4 is more stablized by the setting of groove body, simultaneously support 4 top surface of piece and middle layer 2 Top surface be located in same structure face so that it can between top layer 3 intimate contact so that entire sole body stable structure.

Further, 4 top surface of the support chip, which is equipped in groove body and groove body, is equipped with the vibration damping sheet 5, and vibration damping sheet 5 pushes up Face is located in 2 top surface of the middle layer, so that the mounting structure of vibration damping sheet 5 is more stablized by the setting of groove body, while vibration damping sheet 5 Top surface and 2 top surface of middle layer are located in same structure face, make its can also between top layer 3 intimate contact so that entire shoes Copy for the record or for reproduction body stable structure.

Further, vacancy section 8 there are two being all provided in the middle part of the middle layer 2, vacancy section 8 is between two panels bottom 1, and two A vacancy section 8 is distributed before and after sole body length direction, and the setting of vacancy section 8 is ensureing that sole body is wear-resisting and skid-proof function Under the premise of mitigate sole weight.

The vacancy section 8 is located at 4 lower part of the support chip and 4 bottom surface of support chip and is equipped with and is located in the vacancy section 8 Locating piece 9, the structure can increase the stereovision and aesthetics of sole body, simultaneously support the realization of 4 underrun locating piece 9 of piece Lower part positions so that the mounting structure of support chip 4 is more stablized.
