"Apparatus for blow molding hollow plastic containers, and method for inserting and locking a pre form in a pre-determined position on a pair of half molds and blow molding.It is a device for blow molding plastic containers, comprising a plurality of pairs of half moulds (1, 2) that can be coupled to each other.Separate from each other and subjected by clamping between them, these pairs (1, 2) and is associated with a central structure appropriately and consisting of a stationary half mould (1),That is substantially coupled to the structure, and a respective half mobile mould (2) capable of being opened and made by fastening with a rotational movement.They are equipped with devices (3, 4) adapted to have a respective pre form (7) at a preset position adapted for blow moulding.And to keep the pre form (7) in this position regardless of the position of the respective half moulds (1, 2).These means being in particular, consisting of: a means of fork (3) firmly connected to a respective stationary half mould (1),A middle claw grip type clamp (5) adapted to transfer a respective pre form (7) of an external position and fit the same in its middle fork (3),And a number of small tube (4) adapted to be inserted into the opening of the mouthpiece of the pre form (7) when the latter is embedded in the middle of the fork (3).
