Preferably, the outer surface of the billet core is coated with a teflon release coating with a thickness of 0.01mm-4 mm.

Preferably, the thickness of the Teflon demoulding coating coated on the surfaces of the bottle cap stopping cavity and the bottle mouth spiral cavity on the inner wall of the blank core seat is 0.01mm-4 mm.

Has the advantages that:

the utility model discloses carry out revolutionary improvement to the base core of traditional plastic bottle blowing opening and closing machine, the base core that changes traditional integrative structure whole into can singly change, the enterprise only needs to dispose the monomer base core of many different specification and dimension and a set of rotary mold of installation base core, when producing the plastic bottle of different specification and dimension, only need dispose the base core of installation different specification and dimension, and correspond the base core cover mould of different specification models, cooperate the bottle mould that opens and shuts of different specification and dimension, can satisfy the plastic bottle that a set of bottle blowing opening and closing machine can batch production different specification and dimension, coat with the special fluorine dragon coating that can come off the membrane for a long time to the surface of base core simultaneously, very big improvement enterprise's blowing bottle production efficiency, reduced the multiple mould equipment purchasing cost of blowing bottle of different specification and dimension, the intensity of labour that the mould was changed, has the beneficial effect of great technical progress.
