Specific implementation mode
With reference to specific embodiment, the utility model is expanded on further.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it should also be understood that, in the content for having read the utility model instruction
Later, those skilled in the art can make various changes or modifications the utility model, and such equivalent forms equally fall within this Shen
It please the appended claims limited range.
As shown in Figure 1, Figure 2 and Figure 3, the utility model provides a kind of flow channel of injection die steering of included detent mechanism
Axis comprising axis body, axis body top surface are equipped with runner 5, and axis body top center is equipped with interior hexagonal counterbore 6, and axis body bottom is equipped with hook
3, it sets on 3 circumference of hook there are two the arc-shaped boss 4 for being in symmetry arrangement, axis body bottom centre is equipped with axis body counterbore 7, shaft-body side
Face lower end is until bottom is equipped with the U-type groove 2 of perforation.
As shown in Figure 4, Figure 5 and Figure 6, mould type cavity block 9 is equipped with sprue 10 and runner 11, the both ends of sprue 10
Respectively with two 11 vertical connections of runner, the center that sprue 10 and runner 11 cross is equipped with through-hole 14, in through-hole
14 bottoms are equipped with concentric mold counterbore 13, and four arc grooves 12 are distributed in decile on 13 circumference of mold counterbore.Runner 11
End connect cavity 8.
Runner steering shaft 1 is mounted in the through-hole 14 of cavity block 9, and the hook 3 and cavity block 9 of 1 bottom of runner steering shaft are logical
13 step of mold counterbore of 14 bottom of hole matches, the circular arc boss 4 on 1 bottom hook of runner steering shaft, 3 circumference and 9 mould of cavity block
