Description

DEVICE FOR MANUFACTURING FOOTWEAR FLOORS WITH INSERTIONS CHROMATICS AND PRODUCT OBTAINED OBJECT OF THE INVENTION

The present invention, as expressed in the statement of this specification, refers to a device for manufacturing footwear floors with chromatic inserts and product obtained.

The device is determined from a mold that comprises, in principle, a base and a cover for closing the injection mold as conventionally, including characteristic means for holding an intermediate part constituting an insert that once the floor assembly has been manufactured, a legend or any other corresponding logo will be seen from the outside only with a part of the front surface of such an insert, the same being embedded in the material injected from the

floor,

to the time that such insert will be visible by both faces

of the

floor determined by a body laminate from true

thickness.

Is

applicable too to the obtaining from graphics Y

brands

in bicolor with any material, and even

applicable

to different accessories of the footwear.

Thus, the essentiality of the invention is that in a single injection of material a logo or brand in bas-relief with a different color, if desired, is obtained to the whole of the material injected from the footwear floor.

BACKGROUND OF THE INVENTION

At present, the inserts sewn to the shoe cut are known and the inserts attached to the cut and floor of the footwear are also known.

There are also inserts injected on the floor, but using sequential injection technology (bijection).

DESCRIPTION OF THE INVENTION

The invention proposes a device for manufacturing footwear floors with chromatic inserts, the invention also referring to the product obtained.

The device comprises a plastic injection mold that includes a base and a closing lid that incorporates characteristic reception reliefs separated by intermediate grooves where the material enters the interior of the mold, conforming on the face

10 free of such receiving reliefs, recesses that together delimit a recess where an insert is fitted that once obtained the whole floor, such an insert is embedded in the material of the floor itself, seeing part of the insert from the outside on both sides of said floor.

15 In turn, the base of the mold incorporates protrusions facing the receiving reliefs of the cover, so that when the injection mold is closed, the protrusions of the base stop against the free face of the insert, whereby , the injected material will occupy all

20 the intermediate grooves of separation between the receiving reliefs, as well as other voids existing in such receiving reliefs, also filling the injected material voids existing in the insert, holes

existing in the protrusions of the base and also the space

25 side that borders such protrusions of the base, thus conforming the logo or brand that will be seen from one of the outer surfaces of the floor assembly, once formed, corresponding that logo or mark with the front of the protrusions of the base, since such

30 projections stop against the insert at the time of closing the mold assembly. On the other even surface of the floor you will see part of the insert, although this part that is seen does not correspond to the logo or brand provided, but with the grooves

35 separation intermediates of the receiving and hollow reliefs incorporating such receiving reliefs.

Thus, the projections of the base of the mold prevent a part of the surface of the logo from hiding with the material injected from the floor, generating grooves in this injected material that reveals that part of the

5 conforming front surface of the logo or graphic or brands sought.

Next to facilitate a better understanding of this descriptive report and forming an integral part of it, some figures are accompanied in which with character

Illustrative non-limiting object of the invention has been represented.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1. - Shows a perspective view of a representative mold of a device for manufacturing floors

15 of footwear with chromatic inserts, object of the invention. Also object of the invention is the product obtained determined basically by a characteristic footwear floor.

Figure 2.- Shows a plan view of the floor 20 obtained by its outer support face on the floor. Figure 3.- Shows a plan view of the floor obtained by its inner face. Figure 4.- Shows a sectional view of the floor through the area that incorporates the insert embedded in the material injected from the floor of the shoe.

DESCRIPTION OF THE PREFERRED EMBODIMENT

Considering the numbering adopted in the figures, the device for manufacturing shoe floors with chromatic inserts is determined from an injection mold 1

30 made of plastic comprising a base 2 and a closing cover 3 of the assembly of the injection mold 1.

The closing cover 3 incorporates in its inner face some receiver reliefs 4, affected in their free faces of recesses 5 that together delimit a recess where

35 an insert 6 that can have

the same height or even greater than the depth of those recesses 5. On the other hand, the base 3 of the injection mold 1 incorporates protrusions 7 facing front and

5 evenly with the receiving reliefs 4 of the closing cover 3, so that when the mold 1 is closed, the projections 7 of the base 2 of the mold 1 butt against the free face of the insert 6. Said projections 7 are the elements that determine the logo, brand or graphic

10 corresponding, so that such projections 7 generate in the assembly of the floor 8 by its rear face 9 of support on the ground, some rear grooves 10, whose bottoms comprise part of one of the faces of the insert 6, bottoms which determine the logo, brand or configuration

15 corresponding graph. Both the receiving reliefs 4 of the closing cover 3, as well as the insert 6 and projections 7 of the base 2 incorporate different gaps 11-12-13 to facilitate the passage of the injected material to manufacture the floor assembly 8

20 with the incorporation of the insert 6, so that once the material of the floor 8 is injected, it occupies all the free space inside the closed mold 1, the insert 6 being then embedded in the material injected from the floor 8.

25 On the front face 9 'of the floor 8 other anterior grooves 10' formed by the receiving reliefs 4 are formed, so that the bottoms of such anterior grooves 10 'constitute a visible part of the insert 6 corresponding to the plantar configuration of the

30 intermediate grooves 14 and holes of the receiving reliefs 4, as well as other grooves 14 'which also affect the receiving reliefs 4.

The intermediate grooves 14 separate the receiving reliefs 4, intermediate grooves 14 where the material enters into the mold 1.
