Detailed Description
As shown in fig. 2-6, the utility model relates to a whole ejecting mould of circular arc loose core hank tooth, including movable mould board 1, motor 2, drive gear 3, core gear 4, gear tooth core 5, slider guide block 6, move back tooth mold insert 7, hydro-cylinder 8, hydro-cylinder fixed plate 9, slider seat 10, pull rod 11, curved core slider 12, curved core 13.
The motor 2, the transmission gear 3, the core gear 4, the gear tooth core 5, the slide block guide block 6 and the tooth withdrawing insert 7 form a thread mechanism; the oil cylinder 8, the oil cylinder fixing plate 9, the sliding block seat 10, the pull rod 11, the bent core sliding block 12 and the bent core 13 form a core pulling mechanism.
The motor 2 is fixed on the movable template 1, the transmission gear 3 is fixedly sleeved on an output shaft of the motor 2, the transmission gear 3 is meshed with the core gear 4, the core gear 4 is fixedly sleeved in the middle of the gear tooth core 5, the outer end screw teeth of the gear tooth core 5 are in threaded connection with the inner threads of the tooth withdrawing insert 7, the inner side of the gear tooth core 5 is movably arranged in the slide block guide block 6 in a penetrating manner, the inner end of the gear tooth core 5 extends into the cavity, and the slide block guide block 6 and the tooth withdrawing insert 7 are both fixed on the movable template 1; the cylinder body of the oil cylinder 8 is fixed on the side wall of the movable mould plate 1 through an oil cylinder fixing plate 9, the rod end of a piston rod of the oil cylinder 8 is connected with a sliding block seat 10, the sliding block seat 10 is connected on the movable mould plate 1 in a sliding mode, the outer end of a pull rod 11 is hinged on the sliding block seat 10, the inner end of the pull rod 11 is hinged with a bent core sliding block 12, the bent core sliding block 12 is connected on the movable mould plate 1 in a sliding mode, the outer end of a bent core 13 is hinged on the bent core sliding block 12, and the outer end of the bent core.
The utility model discloses a theory of operation:
