Specific embodiment
It is described in further detail with reference to the accompanying drawing and by specific embodiment to utility model, following embodiment only describes
Property, it is not restrictive the protection scope of the utility model.
Embodiment
A kind of pcb board activity orientation cutting mould, including upper mold 1 and lower die 3, are respectively set in upper mold 1 and lower die 3
There is upper slitter oralia 2 and cut oralia 5, wherein having stripper plate, stripper plate and 3 bottom of lower die in the periphery floating connection for cutting oralia 5
Guiding and reset function are realized by guide post and spring between plate.Fixed pin 61 and activity are wherein provided on cutting oralia 5
Needle 62, active pointer 62 are fixed on a sliding block 7, and a sliding slot 51 is provided on cutting oralia 5, and fixed pin 61 is in sliding slot 51
Extended line on, and sliding slot 51 is arranged in parallel with the side for cutting oralia 5.The lower part of sliding block 7 is provided with anti-delinking part, section is in
Convex shape, so that anti-limited slip block 7 is detached from from sliding slot 51.A countersunk head threaded hole 71 is provided on sliding block 7, the countersunk head threaded hole
71 are combined with countersunk head screw (being not drawn into figure), to may be implemented between sliding block 7 and sliding slot 51 by the elastic of countersunk head screw
Locking and the effect that unlocks, and due to the setting of countersunk head, countersunk head screw pair when can preventing upper and lower mould 3 from molding
Molding impacts.
Further, fixed pin 61 and 62 pairing of active pointer are molded as interfering in order to prevent, in the upper slitter oralia 2 of upper mold 1
