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 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 cut of the footwear 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 free face of such reception reliefs recesses that together delimit a recess where an insert is adjusted 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.

In turn, the base of the mold incorporates protrusions facing the receiving reliefs of the lid, 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 the intermediate separation grooves between the receiving reliefs, as well as other holes existing in such receiving reliefs, also filling the injected material existing holes in the insert, holes existing in the projections of the base and also the lateral space that It borders such protrusions of the base, thus conforming the logo or brand that will be seen from one of the exterior surfaces of the floor assembly, once it is formed, that logo or brand corresponding to the front of the protrusions of the base, since such projections butt against the insert at the time of closing the mold assembly.

On the other even surface of the floor, part of the insert will be seen, although this part that is seen does not correspond to the logo or mark provided, but to the intermediate grooves separating the receiving and hollow reliefs that incorporate such receiving reliefs.

Thus, the projections of the mold base prevent a part of the surface of the logo from being hidden with the material injected from the floor, generating grooves in this injected material that reveals that part of the front surface that conforms to the logo or graphic or Searched brands

Next, in order to facilitate a better understanding of this descriptive report and forming an integral part thereof, some figures are attached in which the object of the invention has been represented with a non-limiting illustrative character.

BRIEF DESCRIPTION OF THE DRAWINGS

Figure 1.- Shows a perspective view of a representative mold of a device for manufacturing footwear floors with chromatic inserts, object of the invention. Also the object of the invention is the product obtained determined basically by a characteristic footwear floor.

Figure 2.- Shows a plan view of the floor 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 footwear floors with chromatic inserts is determined from a plastic injection mold 1 comprising a base 2 and a closing cover 3 of the injection mold assembly 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 an insert 6 that can have complementary fit

the same height or greater than the depth of these recesses 5.

On the other hand, the base 3 of the injection mold 1 incorporates projections 7 facing frontally and 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 corresponding logo, brand or graphic, so that such projections 7 generate in the whole of the floor 8 by its rear face 9 of support in the ground, some posterior grooves 10, whose bottoms comprise part of one of the faces of the insert 6, bottoms which determine the corresponding logo, brand or graphic configuration.

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 assembly of the floor 8 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.

Other anterior grooves 10 'formed by the receiving reliefs 4 are formed on the front face 9' of the floor 8, so that the bottoms of such anterior grooves 10 'constitute a visible part of the insert 6 corresponding to the plantar configuration of the intermediate grooves 14 and gaps of the receiver reliefs 4, as well as other grooves 14 'that affect

too

to the reliefs receivers Four.
