So, for fear of above-mentioned shortcoming, the objective of the invention is to release a kind of in the end/the outer bottom processing method, promptly the end/outer bottom inserts a bolster, so that not thermal radiation influence, in the method, the perforated foams of Bottom Shape is molded with hot press in being cut into, the hole of inserting bolster is simultaneously molded, and perforated foams and above-mentioned bolster are bonding with footwear together.Add man-hour like this, above-mentioned bolster is enough to play should effect, can the performance of reduction own, also can avoid breaking and bonding bad phenomenon owing to two procedures-mold pressing procedure and plug in bolster operation fully separately cause.
The present invention is the middle end/outer bottom processing method, and its characteristics have been following operation:
A) first suppression process, promptly vinyl obtains soft perforated foams by mold pressing;
B) severing operation, promptly above-mentioned perforated foams scabbles into certain thickness and size with end part trimmer with cutting machine, and is cut into similar middle Bottom Shape;
C) high temperature suppression process promptly is cut into above-mentioned shape, and perforated foams is packed in the metal pattern, and the reusable heat press was 130 ℃～160 ℃ lower mould 10～30 minutes, and the end/outer bottom in the formation forms and bolster shape and the matched bolster jack of size simultaneously;
D) press operation again, promptly above-mentioned perforated foams under 10 ℃～30 ℃, cooled off 10～30 minutes in pattern, and the middle end is made in the demoulding; And
E) insert the bolster operation, promptly relevant end part processing with shoemaking, bolster inserts as is above-mentioned by in the hole that the middle end/outer bottom bolster shape forms, and uses bottom adhesive simultaneously, places the bonding pressing of enclosing cover then at an upper portion thereof.
The cellular-plastic panels that particularly above-mentioned enclosing cover is high physical property constitutes, or injection moulding is low-gravity 0.15～0.35G/cm 3And soft.
In addition, there is a bossing above-mentioned enclosing cover bottom surface, so that engage with elbow packing above the bolster.
Fig. 1 is a reduced graph, represents processing method of the present invention.
Fig. 2 is a reduced graph, represents traditional processing method.
Fig. 1 is a flow chart, represent of the present invention in the end/outer bottom processing method.
Among the present invention the end/outer bottom processing method mainly comprises four procedures, i.e. first suppression process, the severing operation, hot pressing process is pressed operation again and is inserted the bolster operation.
First suppression process is to add some additives in the raw material-resin of the middle end/outer bottom, as crosslinking agent or blowing agent.
Template is processed and the metal pattern of packing into above-mentioned resin compound.Then, with above-mentioned material high temperature, high pressure compacting 10～30 minutes, crosslinking agent or blowing agent are dissolved.If above-mentioned metal pattern is thrown off in proper order by expection, and expands rapidly, then the soft perforated foams 10 of Chan Shenging has independently foaming structure.
The severing operation is that part section trimmer flattens into certain thickness and size with cutting machine at the bottom of perforated foams 10 usefulness of the first suppression process moulding, and be cut into similar in Bottom Shape.So the perforated foams 10 of acquisition has the size and the shape at the similar middle end.
The high temperature suppression process is the perforated foams 10 of the Bottom Shape pattern 14 of packing in being cut into by above-mentioned severing operation, has two or more product models at least, joint-packing.Above-mentioned joint-packing material is used molded 10～30 minutes of hot press down at 130 ℃～160 ℃.Then, perforated foams 10 tentatively be cut into similar in Bottom Shape, accurately be molded as the middle end/outsole shape again, particularly like this by above-mentioned shape molding the middle end ,/outer heel is simultaneously molded with the hole of inserting bolster.
Pressing operation again is after above-mentioned hot pressing process is finished, continuously in the semi-molten of joint-packing state the end/the outer bottom preform, under 10 ℃～30 ℃, cooled off about 10～30 minutes, then, throw off metal pattern two parts up and down, produce the middle end/outer bottom with bolster jack.
Inserting the bolster operation is that bolster 12 inserts bolster jacks 11, according to the above-mentioned operation of pressing again, in the formation end/the outer bottom s heel portion, use subbing and adhesive simultaneously bonding again.In order to cover bolster 12, bonding and enclosing cover 13 of pressing is finished the work of inserting bolster.The result is that the middle end/outer bottom final products that bolster 12 is housed are effectively made.
Above-mentioned bolster can comprise airbag, six janeckeites, and gel and torsion bar are considered some features that every kind of shape is stipulated, can use the bolster that is fit to the footwear characteristics.
Therefore, above-mentioned insertion bolster operation can be carried out simultaneously in conjunction with the end part processing of shoemaking design, and in this case, the independent operation of other of bonding process no longer needs, thereby the insertion operation is simplified more.
There is a crowning particularly above-mentioned enclosing cover 13 bottom surfaces so that engage with elbow packing above the bolster, adopt enclosing cover 13 after, bolster 12 and enclosing cover 13 form overall structures, thereby the insertion portion end-state of bolster can further be solidified.
Simultaneously, because above-mentioned enclosing cover 13 is to use and the middle end/outer bottom processing method similarity method processing, can the be above-mentioned middle end ,/the outer bottom difference is felt to be reduced to a minimum, so bolster shows performance own more.
In other words, it is more effective to process above-mentioned enclosing cover 13 with the following method, promptly behind some additives of mixed with resin, the above-mentioned hybrid resin metal pattern of directly packing into, carries out injection-moldedly, or with other method, i.e. mold pressing is carried out in the such severing of cellular-plastic panels.Enclosing cover 13 with the such moulding of said method is made of the cellular-plastic panels with high physical property, or injection moulding, has low-gravity 0.15～0.35G/cm 3And soft, can pass to heel to bolster 12 spring functions.
So, of the present invention in the end/the outer bottom processing method has the following advantages:
A) owing to insert the bolster operation, heat radiation is degenerated easily, separates with the high temperature suppression process and carries out, and puts to state bolster and influenced by any heat radiation.Thereby its performance (for example, shockproof, buffering is repelled elasticity, and is comfortable etc.) can not reduce.
B) because above-mentioned bolster inserts in end part process simultaneously, can effectively finish, need not increase any operation so insert operation.
As mentioned above, the present invention release a kind of in the end/outer bottom processing method, promptly bolster inserts operation and separates with hot pressing process fully, and above-mentioned bolster can insertion simultaneously in end part process.
