Mold for injection molding, process for producing a piece of plastic and a piece of plastic

摘要

Mold for injection molding, process for producing a piece of plastic and a piece of plastic, the present invention relates to a mold for injection molding of a piece of plastic that comprises at least two adjacent parts consisting of two Ma Tu00e9rias plastics compatible and together by welding or gluing, nature and / or different colors.The mould (1) comprising a moulding cavity (2) bounded by at least two non planar walls (3, 4) and at least a retractable wall (5) mobile between a position of extension, and a position of retraction that allows to divide the moulding cavity (2) in at least two comp. Artimentos (6,7) which are fed separately with plastic.In the position of the retractable extension wall (5) has a non-linear edge (3) which cooperates with a wall without clearance (4) of the molding cavity.The retractable wall comprises a plurality of panels United States (10,11 and 2) at least in the position of extension or retraction position, these panels (10,11 and 12) which are movable in relation to each other so that they can modify the shape of the edge (13) nonlinear of the wall (4) In order to adapt it to the retractable form a second wall of the cavity in the position of retraction.
