The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment this utility model is described in further detail:

By Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6 as seen: this utility model comprises: base plate 6; Following titanium shell section 8 in base plate 6 left sides; The top of infra titanium shell section 8 is settled a upper right titanium shell section 7 and upper left titanium shell section 13 respectively; Comprise the space that to settle the titanium shell between following titanium shell section 8 and upper right titanium shell section 7, the upper left titanium shell section 13; First deflector chute 15 and first demoulding hole 16 are arranged in its spatial outside; On upper left titanium shell section 13, settle the fixedly Magnet 3 of Menas for inner planting artificial cochlea; Bottom electrode section 9 on base plate 6 right sides; The top of infra electrode section 9 is settled one the first top electrode section 10 and the second top electrode section 12 respectively; Comprise the space that to settle electrode section between the infra electrode section 9 and the first top electrode section 10 and the second top electrode section 12; Second deflector chute 17 and second demoulding hole 18 are arranged in its spatial outside; Also settle a demoulding cylinder ejector rod 14 on the infra titanium shell section 8; On upper left titanium shell section 13, upper right titanium shell section 7, the first top electrode section 10 and the second top electrode section 12, the first hold-down mechanism A, the second hold-down mechanism B, the 3rd hold-down mechanism D and the 4th hold-down mechanism C are arranged respectively;

Described hold-down mechanism comprises: a depression bar 1; Be placed on the depression bar 1 and can with base plate 6 fixedly holding screw 2, at the pin 5 of depression bar 1 two sides and the fixing pin 4 of pin 5 and depression bar 1;

On described upper left titanium shell section 13, upper right titanium shell section 7, the first top electrode section 10 and the second top electrode section 12, settle one group two alignment pin 11 respectively.
