and a vertically through air blowing pipe is arranged on the die base and corresponds to the position right below the air inlet channel, the upper end of the air blowing pipe is inserted into the bottom of the air inlet channel, and the lower end of the air blowing pipe is connected with an external air source through a metal hose.
Furthermore, the middle of the mold base is provided with a mounting hole, the lower end of the mold bottom is provided with a mounting column protruding downwards, the mounting column is assembled in the mounting hole, the air inlet duct is opened at the middle of the bottom end of the mounting column, the upper end of the air blowing pipe is exposed out of the mounting hole, and the exposed end is inserted in the air inlet duct.
Furthermore, the die bottom is made of brass.
Compared with the prior art, the utility model discloses beneficial effect embodies:
the utility model discloses an increase the gas blow pipe at the mould base and increase an inlet channel and a plurality of exhaust pore at the mould bottom, form the cooling air gas circuit at the bottom of an unblocked mould, the cooling air design of one side of moulding when having optimized the protruding end glass bottle of bottle-making machine production, continuously cool off at the bottom of the mould through compressed air for speed when the glass bottle shaping, reach the purpose that promotes the production machine speed, avoided because of the mould bottom temperature height causes the quality defect that the bottle end sinks.
