Embodiment
With reference to specific embodiment, the present invention is further explained.It is to be understood that these embodiments are merely to illustrate the present invention
Rather than limit the scope of the invention.In addition, it should also be understood that, after reading the content taught by the present invention, people in the art
Member can make various changes or modifications the present invention, and such equivalent forms equally fall within the application the appended claims and limited
Scope.
Embodiments of the present invention are related to the pulled core structure that a kind of non-slipping block for mould collides, as shown in Fig. 1-3,
Including upper mold seat 1, die holder 2 and core pulling rack 9,1 lower face of upper mold seat is provided with die holder 2, the die holder 2
Side is provided with core pulling rack 9, the take-up housing 3 being provided with the core pulling rack 9 between insertion upper mold seat 1 and die holder 2,
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 and passes through downward
Cross screw 5 is connected with 2 side of die holder, and the anticollision spring 6 in compressive state is provided with the cross screw 5, described
The top of take-up housing 3 upper mold seat 1 on lower end is installed towards the inclined withdrawing block 7 of crash-proof bracket 4, pacify on the take-up housing 3
Equipped with the inclined hole to match with withdrawing block 7, it is disposed with 9 bottom surface of core pulling rack and leads to what 4 extension of crash-proof bracket matched
Hole, take-up housing 3 arrange that 4 one end of crash-proof bracket is disposed with link slot 12, and the link slot 12 is in one end of core pulling rack 9
Connecting rod 11 is installed, gap is left between 12 other end side wall of inserting end end and link slot of the connecting rod 11.
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 with the core pulling rack 9.

Embodiment
When mould 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 whole take-up housing 3 one can be given in the anticollision spring 6 of compressive state
Towards the power of extrapolation, avoid take-up housing 3 from retracting, after oblique pulling block 7 completely disengages, then start 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 during secondary mould closing, bad block is done will not be with
Oblique pulling block 7 collides.
