BLOW MOULD

摘要

A blow mould (1) provided with a locking system to lock each half-mould (2) to the respective half -mould holder (3), allowing simpler and quicker replacement of the lateral half - impressions (4) of the mould (1). The blow mould (1) provides that the lateral half - impression (4) of each half-mould (2) is fixed in a cavity of the corresponding mould holder (3) by means of actuating at least one quick coupling device (5, 5'). Said quick coupling device (5, 5') comprises a force multiplier mechanism (22, 22') configured so as to actuate a respective locking element (29, 29') from an unlocking position, in which the half -mould (2) or a part thereof may be extracted from the mould holder (3), to a locking position, in which half-mould (2) and mould holder (3) are integrally locked to each other, or vice versa.
