Abstract
A mold (10) comprising a plurality of blocks (11, 13) that, in an assembled position, define a mold cavity, the mold being characterized in that it includes at least one pusher (21), said pusher (21) being configured to be housed in a first block (11) of said plurality, in a side facing the mold cavity, and, when the pusher (21) is housed in said first block (11), to present a first surface (S1) flush with the mold cavity, and in that the mold (10) also includes actuator means (23, 25) enabling the pusher (21) to be moved relative to the first block (11), and sealing means (19, 27) configured to isolate the actuator means (23, 25) from the mold cavity.
