Specific embodiment

The technical solution of the utility model is clearly and completely described below in conjunction with attached drawing, it is clear that described Embodiment is one section of point of embodiment of the utility model, rather than the embodiment of full section.Based on the embodiments of the present invention, originally Field those of ordinary skill every other embodiment obtained without making creative work belongs to practical Novel protected range.

It is in the description of the present invention, it should be noted that term " center ", "upper", "lower", "left", "right", " perpendicular Directly ", the orientation or positional relationship of the instructions such as "horizontal", "inner", "outside" is to be based on the orientation or positional relationship shown in the drawings, and is only For ease of description the utility model and simplify description, rather than the device or element of indication or suggestion meaning must have it is specific Orientation, be constructed and operated in a specific orientation, therefore should not be understood as limiting the present invention.

As Figure 1-Figure 4, a kind of rotatable 3D printer cylinder molding device, including rack 1, moulding cylinder 2, electric rotating Machine 3 and rotatable piston panel assembly, 2 two sides of moulding cylinder are hinged by first rotating shaft and rack 1, and the rotating electric machine 3 is pacified In rack 1 and 3 spindle nose of rotating electric machine is connect with the first rotating shaft of 2 side of moulding cylinder, the rotating electric machine 3 for drive at Type cylinder 2 rotates in a vertical plane, and the rotatable piston panel assembly includes piston plate 7, connector 4 and lifting drive, The piston plate 7 is located in moulding cylinder 2, and 7 lower end of piston plate is hinged by shaft screw 8 and 4 top of connector, the company 4 lower section of fitting is connect with lifting drive, and the lifting drive is used to move up and down drive by drive connection part 4 and live Seben 7 moves up and down inside moulding cylinder 2.

The lifting drive is screw rod driving device, and the screw rod driving device includes screw rod and feed screw nut；Institute It states 5 upper end of screw rod and is fixed on 4 lower section of connector, the feed screw nut 6 of screw rod driving device is fixed in rack 1.
