Description

The sole of tool air bag in one-body molded

The utility model relates to a kind of sole, refers to a kind of sole of one-body molded interior tool air bag especially.

The shoemaking industrial circle has preferable wear comfortableness, elasticity and damping property for making sole at present, can set up air-cushion member, You Bao, spring usually in sole ... etc. extra elastic article, reach all good footwear sole construction of elasticity and damping by this; (taking from the Taiwan patent announcement numbers No. 339574) as shown in Figure 1, this promptly is the suitable example of setting up air-cushion member 11 in sole 10; Yet this air-cushion member or oil bag wait the setting of extra spare, must be earlier separately behind moulding air-cushion member or the oil bag individuality, and be arranged at again in the space of the interior reservation of sole and constitute; Therefore, comparatively complicated and cost is high for the processing job procedure of shoemaking industrial circle, and can't meet the actual demand of shoemaking industrial circle fully;

Therefore,, get final product the sole that one-shot forming inside contains the tool air bag, then certainly will can significantly reduce the manufacturing cost of sole, and be met the actual demand of snugness of fit, elasticity and damping property if can see through unitary plastic.

The purpose of this utility model be to provide a kind of one-body molded in the sole of tool air bag, advantages such as this sole has that preferable sense comfortable and easy to wear, damping property are good, weight saving, saving material and preferable elasticity.

The technical solution of the utility model is the sole that is to provide a kind of one-body molded interior tool air bag, and it is characterized in that: this sole is that single material is one-body molded, has most air bags in sole inside, makes the low-density soft area of the local formation of sole.

Described one-body molded in the sole of tool air bag, it is characterized in that: this air bag takes shape in sole inside, with respect to the heel and the sole position of foot.

About the utility model for reaching above-mentioned purpose, technological means that is adopted and effect thereof, lift a preferable possible embodiments now and cooperate graphic detailed description as after.

The explanation of accompanying drawing drawing:

At first please cooperate and consult shown in Fig. 4,5: the sole 30 of a kind of one-body molded interior tool air bag of the present utility model, this sole 30 is that single material is one-body molded, have most air bags 31 in sole 30 inside, make the low-density soft area of these sole 30 local formation.The moulding of this sole 30 is by means of establishing scalable mobile interior die 233 in the mould 20; Wherein:

Please cooperate and consult shown in Fig. 2,3,4, this mould 20 is made of a top board 21, a patrix 22, two acting devices 23 and a counterdie 24; This top board 21, be to be positioned at integrally-built the top: be positioned at top board 21 belows and patrix 22 is correspondences, has default ejaculation running channel 221 in the patrix 22, and offer two through holes 222 at predeterminated position, offer scalariform in through hole 222 upper limbs groove 223 is set, through hole 222 lower edges then form an accommodation space 224 (as shown in Figure 2) that is arranged with by these patrix 22 surfaces;

This acting device 23, be to assemble by die 233 in an operating bar 231, the spring 232 and to constitute, this operating bar 231 is after wearing spring 232 earlier, the through hole 222 that is positioned at patrix 22 is set again, the upper end of operating bar 231 is to be the bigger head 234 of type body, and the bottom of operating bar 231, then with interior die 233 Joints, die 233 just can hold in the accommodation space 224 that is embedded in patrix 22 its through hole 222 lower edges in this; This counterdie 24 is and the corresponding closing in patrix 22 belows, and can carries out the start of open and close mould with patrix 22, forms sole die cavity 241 (as shown in Figure 2) in counterdie 24;

This sole 30, be to penetrate one-body molded with plastics by above-mentioned mould 20, and the forming process of this sole 30 is: when top board 21 pressing patrixes 22 top end faces, the head 234 of these acting device 23 its operating bars 231, can be subjected to the pressing of top board 21 and interlock make operating bar 231 its in addition interior dies 233 of end sink to being positioned at the die cavity 241 (as shown in Figure 3) of counterdie 24; Ejaculation running channel 221 by patrix 22, but jet-out plastic is filled in die cavity 241, (plastics in the die cavity do not solidify yet fully) removes top board 21 after treating the scheduled time, at this moment, the head 234 of operating bar 231 is pressurized not, and be subjected to the elastic force start of spring 232, shift out die cavity 241 and be positioned at accommodation space 224 (as shown in Figure 4) and be able in the interlock die 233; It should be noted that, shift out in the process of die cavity 241 in interior die 233, die 233 shifted out the space of being vacated in plastics in the interior die 233 meeting traction die cavitys 241 occupied, and caused this space to be occupied by low-density plastics (gone out by the die traction) and air, and formed most air bags 31; In view of the above, many air bag 31 structures of tool in the precalculated position of these sole 30 inside (the shared place, space of die originally) formed, the plastic construction (as shown in Figure 5) of higher density is then kept in all the other zones of sole 30.

What deserves to be mentioned is that this sole 30 is in forming process, the plastics of sole 30 appearances are closely to recline mutually with die cavity 241, and are shaped to the higher plastic construction of density, and the plastic construction that this density is higher is complete the presenting that helps die cavity 241 thin portion decorative patterns; And sole 30 inner predetermined position density are lower and contain the low density plastics's structure that is mixed with most air bags 31, and being to provide sole 30 to have preferable sense comfortable and easy to wear (the inner appropriateness of sole is soft), damping property, weight saving, saving material and preferable elasticity (the event of the inner tool air bag of sole); When reality is implemented, these air bag 31 shaping structures can be positioned at sole 30 its heel and sole positions with respect to foot.

In sum, forming process of the present utility model is to penetrate one-body molded sole with plastics, and in sole ejection formation process, shift out the interior die of mould in good time, die shifts out and draws the inner plastics of sole and occupy the space that die shifts out in the mat, make the inner low density plastics's structure that includes most air bags that forms of sole, the sole remainder is then kept the plastic construction of higher density, in view of the above, sole of the present utility model have that preferable wear comfort, damping property are good, advantage such as weight saving, saving material and preferable elasticity.
