One end is connected across the through-hole with a driving device, and the liftout plate is consistent with cavity bottom shape.
A kind of die casting with ejecting mechanism, the liftout plate outside are provided with sealing ring.
A kind of die casting with ejecting mechanism, the liftout plate lower section are provided with spring.
A kind of die casting with ejecting mechanism, the dynamic model are connected with dynamic model seat, and the cover half is connected with
Cover half seat.
A kind of die casting with ejecting mechanism, is provided with gas vent on the dynamic model, on the dynamic model seat
It is connected with exhaust pipe.
A kind of die casting with ejecting mechanism, channel is offered on the cover half, and the channel side connects
