PURPOSE:To fix a component in a hollow molding without necessity of providing a specific opening therein by integrating a material to be fixed in the piece through a stay by molding a parison. CONSTITUTION:Mounting brackets 14 secured to the ends of both two stays 13 disposed radially oppositely to a flange 12 provided at the end of a blow pipe 11 by inserting the rear ends of two stays 13 into the flange 12, and a component 15 fixed or secured thereto are detachably attached to the end of the pipe 11. Then, the pipe 11 is disposed between injection metal molds 16 of opened state, and the end of the pipe 11, the brackets 14 and the component 15 are wholly enclosed by a parison 17 extruded from the die of an extruder. The upper and lower ends of the parison 17 are closed by closing the molds 16, compressed air is blown from the pipe 11 into the parison, and the parison 17 is molded in a shape copying the periphery of the cavity of the molds 16. |
