<p>PURPOSE:To manufacture simply a tube body having a reinforcement embedded therein such that the inner and outer diameters are constant and further improve an operational environment by loading liquefied material in a cavity, locating and setting a bore forming core pin having a thin wall tube covered with the reinforcement in a cavity of a lower die to set an upper die to the lower die for press molding. CONSTITUTION:After a fixed amount of about 50 hardness liquefied silicone rubber is evenly discharged and loaded in a cavity 31 of a lower die 30 having a trachea pin 28 set therein by a fixed amount discharger, a prepared core pin 33 is set in the lower die 30. A fixed amount of liquefied silicone rubber is discharged into a cavity of an upper die by the constant amount discharger. Then, the upper die is quickly set to the lower die 30 for press molding with fixed pressure at about 130 deg.C for several minutes. Thereafter, the dies are opened to take out the core pin 33 and a tube body 21 with the trachea pin 28. First, the trachea pin 28 is drawn out of the other end side of the tube body 21 by pincers having pointed tips or the like to ensure the cough trachea 27, and then the core pin 33 is drawn out by air pressure or the like.</p> |
