3D forming film manufacturing device and 3D forming film manufacturing method using same

A device for manufacturing a 3D forming film with a mold, the device comprising:

• a press head unit positioned to be distanced from the mold;
• and
• a variable volume body coupled to the press head unit and having elasticity so that a volume thereof is variable due to gas introduction and discharge,
• wherein the variable volume body is configured to be in contact with a forming film positioned in or on the mold in accordance with a volume change of the variable volume body,
• wherein the variable volume body is configured to press the forming film so that the forming film is molded in a 3D shape,
• wherein the press head unit comprises:
• a press frame;
• an up-and-down moving body coupled to the press frame and configured to move linearly up and down;
• a press motor coupled to the up-and-down moving body;
• a press head having a lower portion on which the variable volume body is mounted;
• a screw shaft having a first end connected to the press motor and a second end screw-coupled to the press frame to perform a rotational motion and an up-and-down linear motion,
• wherein the press head unit includes a press head guide shaft which is coupled to the press head and guides an up-and-down linear motion of the press head such that when the screw shaft rotates, the press head does not rotate but move linearly up and down along the press head guide shaft.
