A mould (4) for over-moulding and/or encapsulating a sheet (8) comprising a punch (16), a matrix (20) suitable for closing on the punch (16) so as to delimit with the latter an injection chamber (24), with the matrix (20) and the punch (16) being movable axially to each other relative to an opening/closing axial direction (Y-Y) of the mould (4), an insert (28), slidably associated with said matrix (20) along at least said axial direction (Y-Y). Advantageously, the mould (4) comprises at least one closing and locking wedge (32) provided with a thrust wall (36), inclined, sliding on an inclined plane (40) associated with the insert (28), so that the displacement of the closing and locking wedge (32) along an actuating direction (X-X) leads to a translation of the insert (28), relative to the matrix (20) and the punch (16), along the axial direction (Y-Y). The invention also relates to the related method for over-moulding and/or encapsulating a sheet (8) comprising the mould (4). |
