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.
The embodiment of the utility model is related to a kind of pulled core structure that the non-slipping block for mold collides, such as 3 institutes of Fig. 1-
Show, including upper die holder 1, lower die holder 2 and core pulling rack 9,1 lower face of upper die holder is equipped with lower die holder 2, the lower die
2 sides of seat are equipped with core pulling rack 9, and the sliding block being inserted between upper die holder 1 and lower die holder 2 is equipped in the core pulling rack 9
Seat 3, the take-up housing 3 is disposed with crash-proof bracket 4 close to one end of core pulling rack 9, and the crash-proof bracket 4 extends simultaneously downward
It is connected with 2 side of lower die holder by cross screw 5, the anticollision spring 6 in compressive state is installed on the cross screw 5,
Lower end is installed towards 4 inclined withdrawing block 7 of crash-proof bracket, the take-up housing 3 on the upper die holder 1 of 3 top of take-up housing
On the inclined hole to match with withdrawing block 7 is installed, be disposed on 9 bottom surface of core pulling rack and 4 extension of crash-proof bracket match
Through-hole, take-up housing 3 arranges that crash-proof bracket 4 one end is disposed with link slot 12, and the link slot 12 is close to the one of core pulling rack 9
Connecting rod 11 is installed, there are skies between 12 other end side wall of inserting end end and link slot of the connecting rod 11 in end
Gap.
The connecting rod 11 is in dumbbell shaped, and insertion end and 12 bottom surface of link slot of connecting rod 11 interlock.
The core pulling oil cylinder 10 that mandril is connected with connecting rod 11 is horizontally installed in the core pulling rack 9.
When mold is in molding state, anticollision spring 6 is in the extreme position of contraction state.
3 upper surface of take-up housing is disposed with chamfer trapeze cut on 1 side of upper die holder, upper die holder 1 with fall

Embodiment
When mold molds, pulling block 7 oblique first can unplug take-up housing 3 with product, when unpluging, take-up housing 3
Slightly offset towards outer mobile a distance so that oblique pulling block 7 is deviate from, and entire take-up housing 3 one can be given in the anticollision spring 6 of compressive state
Towards the power of extrapolation, take-up housing 3 is avoided to retract, after oblique pulling block 7 completely disengages, then starts core pulling oil cylinder 10, by core pulling with
Product completely disengages, and core pulling is completed, since take-up housing 3 itself does not shift so that when secondary mould closing, bad block is done will not be with
Oblique pulling block 7 collides.
