Method for changing mold of molding device for manufacturing thermoplastic bottle, involves moving mold holders from closed position to open position to extract sub-assembly, and removing sub-assembly from reference position

摘要

The method involves controlling fixation units for releasing half molds when mold holders (14) are in a closed position. The half-molds are joined together by assembling units to form a unitary transportable sub-assembly. The mold holders are moved from the closed position to an open position to extract the sub-assembly according to a translation movement such that the sub-assembly remains in a reference position. The sub-assembly between the mold holders is removed from the reference position. An independent claim is also included for a fixation device for changing a mold of a molding device for manufacturing a container.
