Specific embodiment
With reference to specific embodiment, the present invention will be further described in detail, but is not limited to these embodiments.
As shown in the drawings, can take out, during a kind of die sinking, the mould that tooth extracts slide insert out simultaneously, including cover half 1 and calmly
The dynamic model 2 of mould 1 cooperation, the injection die cavities 3 being formed between dynamic model 2 and cover half 1, the slide insert being plugged in injection die cavities 3
4th, can be around the thread mold insert 5 that Pivot Point Center line rotates, the drive mechanism for driving thread mold insert 5 to rotate.
Injection die cavities 3 have two groups and the fore-and-aft direction along mould is symmetrical arranged, and every group of injection die cavities 3 are correspondingly arranged on one
Slide insert 4 and two groups of thread mold inserts 5.Two groups of thread mold inserts 5 at every group of injection die cavities 3 are respectively symmetrically and are arranged at this injection molding
