A mould for the production of closures with tear-off membrane in a compression moulding machine, includes: a male die element including a first abutment surface and a female die element. movable relative to each other along a moulding orientation. The mould is positionable between a closed configuration, in which the male die element and the female die element are in contact with each other, and an open configuration, in which the male die element and the female die element are spaced apart. The female die element includes: a first block, a second block and a third block, aligned with each other and movable along the moulding orientation; a first spring, interposed between the first block and the second block; a second spring, interposed between the second block and the third block and configured to apply an opening force along the moulding orientation. The first spring is configured to apply a closing force along the moulding orientation to keep the second block and the first block in contact with each other when no other forces are applied.
