Mould, particularly injection mould, and injection moulding method using such a mould

A method of fabricating a part by injection molding, the method comprising the following steps:

• providing a mold having a plurality of blocks that, when in an assembled position, define a mold cavity, the mold including at least one pusher, said pusher being housed in a first block of said plurality in a side facing the mold cavity, and presenting a first surface flush with the mold cavity, the mold also including an actuator enabling the pusher to be moved relative to the block in which it is housed, and a seal isolating the actuator from the mold cavity,
• wherein, when the blocks are in the assembled position, a second surface of said pusher is in contact with a second block other than the first block, and in that the actuator is accessible via said second surface of the pusher;
• injecting a material into the mold cavity in order to form the part;
• opening the mold cavity by separating at least one block of said plurality of blocks and other than the first block from the remainder of the mold;
• and
• actuating the actuator to cause the pusher to move relative to the first block so that the pusher exerts a force on the part in order to separate the part from the mold.
