されている。 In FIGS. 1 to 3, reference numeral 1 denotes a pair of left and right molds for blow molding synthetic resin, and cavities 2 with open opposing surfaces are symmetrically formed in the pair of molds 1. The cavity 2 formed by this pair of molds 1 includes a cylindrical hollow duct body forming part 3, a parallel cylindrical hollow holder forming part 4 adjacent to this, and a hollow communication hole connecting these two. It consists of a forming part 5. Furthermore, annular protrusions 6 are provided on the inner peripheral surface near both ends of the hollow duct body forming part 3, and circular hole-shaped spaces 7 are provided at both ends of the hollow holder forming part 4 along the center line. They are installed consecutively. Further, above the central position of the pair of molds 1, a parison extrusion port 8 and an air blowing pipe 9 are provided within the parison extrusion port 8.
そして、まず、パリソン押出口８から合成樹脂

気吹込管９から空気を少し吹込んで鎖線Paのよ
うにプリブローさせる。 First, a synthetic resin parison P is introduced from the parison extrusion port 8 into the middle of the pair of molds 1, and a little air is blown from the air blowing pipe 9 to pre-blow it as indicated by the chain line Pa.
ついで、一対の金型１を閉じ、さらに空気吹込

態で同時に成形される。 Then, when the pair of molds 1 are closed and air is further blown from the air blowing pipe 9, the parison P in the cavity 2 expands until it comes into close contact with the 2 surfaces of the cavity.
The parison P outside the cavity 2 is crimped by a cutting blade on the periphery of the cavity 2, and the hollow molded body along the inner surface of the cavity 2, that is, the hollow duct body 11 and the hollow holder 12, are supported with a hollow communication hole 13. They are simultaneously molded while being integrally connected by the piece 14.
ついで、一対の金型１を開いて中空成形体を取
出し、バリを除去する。 Next, the pair of molds 1 are opened, the hollow molded body is taken out, and the burrs are removed.
このようにして得られた中空成形体には、中空

調ダクト２０を形成する。 In the thus obtained hollow molded body, cut line grooves 15 are formed on the outer circumference near both ends of the hollow duct body 11 by the annular protrusions 6 provided on the inner circumferential surface near both ends of the hollow duct body forming part 3. At the same time, the hollow holder 1 is
A cylindrical raised portion 16 is formed at both ends of the cutter 2, and a cut line 17 is formed at the base of the raised portion 16. and,
Both ends of the hollow duct body 11 are cut out along the cut line groove 15, and cylindrical raised parts 16 at both ends are cut out along the cut line 17 of the hollow holder 12.
A harness insertion hole 18 is formed inside the hollow holder 12, and a slit 19 is formed along the outside parting line of the hollow holder 12 to create a vehicle air conditioning duct 20 having a harness holder as shown in FIG. form.

Both sides of the harness 21 are elastically opened through the slit 19, the harness 21 is inserted into the insertion hole 18, and the slit 19 is unexpanded and elastically contracted to hold the harness 21.
なお、スリツト１９からの空気洩れが危惧さ

で、型開きに支障を来たすことはない。 In addition, in carrying out the implementation, instead of providing the support piece 14 as in the previous embodiment, as shown in FIGS. The hollow holder 12 may be formed directly, and in this case, there will be no undercut even if it is not provided along the parting line, so there will be no problem in opening the mold.
