DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to Figures 3 and 4, a preferred embodiment of an anchor device of this invention is fabricated by means of an injection molding mold 5 as described hereinbelow. The mold 5 has an axial hole 50 formed along a longitudinal axis thereof, and a plurality of (in this embodiment, four) grooves 51 extending radially from the axial hole 50. Each of the grooves 51 has a radial width which increases gradually in a direction from a first end 500 to a second end 501 of the axial hole 50, and an enlarged receiving space 52 formed adjacent to the second end 501 of the axial hole 50.
An iron shaft 6 is disposed in the axial hole 50 of the mold 5, as best illustrated in Figure 4. The rear end of the iron shaft 60 extends into the receiving space 52 of the mold 5 and is connected to a disc member 61. The front end of the iron shaft 60 is formed with a tapered head member 60 which extends out of the first end 500 of the axial hole 50. An annular gap 62 is formed between the iron shaft 6 and the internal face defining the axial hole 50 of the mold 5 when the mold 5 is closed, as best illustrated in __7__ 2 1 99650 Figure 5.
A molten plastic material is injected into the annular gap 62 of the mold 5 around the iron shaft 6 in order to fill the grooves 51 and the receiving space 52. A forming die 53 is moved into the receiving space 52 of the mold 5, as best illustrated in Figure 6, in order to depress the plastic material in the receiving space 52. After the plastic material is cooled and hardened, the forming die 53 is retracted from the receiving space 52 of the mold 5.
