Abstract

Improvements in molds for the manufacture of footwear with injection molded sole and insole with different colored plastic material, comprising two jaws movable with respect to each other that define the lateral contour of the sole and the insole to be molded, a base inserted between the jaws, which bears the tread pattern of the sole, a shovel-carrying last, approximate and removable with respect to the free edge of the jaws to respectively close and open upper the mold cavity limited laterally by the jaws and lower by said base, as well as two through conduits through at least one of the jaws and located at different levels for the introduction of plastic materials of different colors into the mold cavity, characterized by the fact that said base (3) is fixed with respect to the jaws (1) and (2) in a position in which it determines with respect to the edges A molding cavity (4) of thickness substantially equal to the total thickness of the sole (S) and the insole (G) to be molded with different colored plastic material is free (1a) and (2a) from the jaws. base is provided with a tubular conduit (10) formed in the body of the same base, the conduit of which, on the one hand, is in communication with one of the conduits (9) passing through one of the jaws for the introduction of a plastic material of a certain color, while on the other side it opens through a hole (11) into the aforementioned molding cavity (4) and by the fact that, in addition, it comprises a plate-shaped body auxiliary (7) introduced between the aforementioned jaws (1) and (2) in the molding cavity (4), when the last (5) with upper (6) is in a position separated from the edges (1a) and (2a) of the jaws, and then removable, located with respect to the base (3) so as to determine a partial mold cavity or (4a) of thickness substantially equal to the thickness of the sole (S), whose plate-shaped body (7) is provided with a plurality of blind holes (12) open towards said partial molding cavity (4a), as well as a protruding pin (13) towards the base (3) to close said hole (11), said partial mold cavity (4a) being in communication with the other conduit (8) passing through one of the jaws for the introduction of a plastic material of another certain color.
