It sets the 61 rough driving moulding cylinders 20 to move, and the moulding cylinder 20 is accurately driven by second driving device 62
Movement, improves the efficiency of driving and ensure that the exactitude position of docking；It is located at institute by the way that second electric interfaces are arranged
The side of opening of the moulding cylinder 20 far from shell is stated, so that when the moulding cylinder 20 is driven to below the base station 30, institute
The second electric interfaces are stated to be electrically connected with first electric interfaces；By described in the connection of connecting plate 42 with sealing ring and sealing
Moulding cylinder 20 and the base station 30, so that the moulding cylinder 20 and the shaping work room 40 form sealing space；By described
Glove box 41 controls the manipulator 70 and moves, and avoids air into the shaping work room 40 and is formed by close encapsulation
Chamber causes the oxidative damage to metal powder or molded part；It ensure that the reset of the moulding cylinder 20 by the resetting apparatus.
Obviously, the present invention can also have other deformations, such as the moulding cylinder holding part or the base station holding part 311 can
It omits, correspondingly, the quantity of the connecting plate supporting piece 421 is one；And/or control device 80 described in person is also controllable described
First driver 613 drives the gear 612 to rotate and move along the rack gear 611, drives the supporting plate 13 along institute
It states guide rail 11 to move far from the base station 30, to drive the moulding cylinder 20 to move far from the base station 30 until moving to just
Beginning position is prevented since the moulding cylinder 20 can not reset caused by the reset force of the resetting apparatus is inadequate.
Those skilled in the art it should be appreciated that more than embodiment be intended merely to illustrate the present invention,
And be not used as limitation of the invention, as long as within spirit of the invention, it is to the above embodiments
It is appropriate to change and variation is all fallen within the scope of the present invention asks protection.
