Embodiment
To further illustrate each embodiment, the utility model is provided with accompanying drawing.These accompanying drawings are in the utility model discloses
A part for appearance, it can coordinate the associated description of specification to explain the running of embodiment original mainly to illustrate embodiment
Reason.Cooperation refers to these contents, and those of ordinary skill in the art will be understood that other possible embodiments and this practicality are new
The advantages of type.Component in figure is not necessarily to scale, and similar element numbers are conventionally used to indicate similar component.
The utility model is further illustrated in conjunction with the drawings and specific embodiments.
With reference to shown in Fig. 3 and Fig. 4, back-off core-pulling die in a kind of hole this embodiment disclose, including cover half 2 and dynamic
Mould 3, the dynamic model 3 is provided with dynamic mould core 4 and lateral component 50, corresponding, and the cover half 2, which is provided with, promotes the lateral component
The inclined guide (invisible in figure) of 50 movements.
In conjunction with Fig. 4, Fig. 5 and Fig. 6, this lateral group, 50 include side slide block 5 and are installed on the side slide block
Side core_pulling, the side core_pulling includes fixed core 52 and moving core 51；The moving core 51 is to be movably installed in
On the fixation core 52, specifically：The fixation core 52 is provided with a line slide rail 521, and the moving core 51 is straight by this
Line slide rail 521 is movably installed on the fixation core 52.
The end of the moving core 51 is provided with a back-off portion 511, for back-off in forming hole 11；To realize back-off in hole
