Description

Cold and hot design all-in-one of toe cap heel

Technical Field

The utility model relates to a shoemaking equipment especially relates to a cold and hot design all-in-one of toe cap heel.

Background

Whether the shoe is beautiful and comfortable depends on whether the vamp can be shaped according to the pre-designed shape.

The shaping of the rear part of the vamp, namely the heel part, is relatively simple, the heel is easy to completely wrap the back shoe-tree due to the large longitudinal depth of the heel, and the heel is pressed on the back shoe-tree after being heated and softened to be cooled and shaped; the front part of the vamp, namely the toe cap, is difficult to shape, and the toe cap is difficult to wrap the front last due to the small longitudinal depth of the toe cap, so that when the toe cap is cooled and shaped, in order to ensure accurate positioning and wrapping, the front last covering mold is moved to the periphery of the front last and positioned, and then the front last covering mold can be further pressed down for wrapping, and the toe cap can be accurately positioned and wrapped on the front last through the front last covering mold.

Because the control of the shaping of the toe cap is complex, and when the size of the shoe is changed, the changed distance is not only the distance between the tip of the toe cap and the heel of the shoe, but also the height difference between the surface of the toe cap and the lower edge of the heel of the shoe is changed, so that the heating and softening of the heel and the toe cap of the shoe upper at present are carried out separately, and the defects of inaccurate alignment exist in the separated shaping, and the toe cap and the heel of the shoe are easily inconsistent.

Many people attempt to design a shoe upper forming machine capable of simultaneously performing heel and toe (i.e. whole shoe upper) by sleeving the shoe upper on a front last and a rear last and then tensioning the shoe upper from the front to the rear direction by a translation mechanism, which is easily conceivable, but, as mentioned above, when the size of the shoe is changed, not only the distance between the toe portion and the heel is changed, but also the height difference between the surface of the toe and the lower edge of the heel is changed, since the rear last has a large longitudinal depth, the heel is heated, softened and cooled and formed by simply wrapping the rear last, so that the height position of the rear last is not generally required to be adjusted, and the height position of the front last is required to be adjusted according to the size of the shoe, but if the height position of the front last is adjusted, all processing structures corresponding to the front last, such as translation, lowering positioning, pressing, wrapping and the like, must be adjusted accordingly, obviously, the shoe upper shaping device is difficult to realize and is not scientific, so that the shoe upper shaping device capable of realizing one-time shaping does not exist at present.
