Rotatable mold apparatus

A rotatable mold apparatus comprising:

• a first mold disposed on a first base structure and configured to move together with the first base structure;
• a second mold disposed on a second base structure and configured to move together with the second base structure in order to couple to or decouple from the first mold;
• a drive device installed between the first mold and the first base structure and connected to the first mold;
• and
• support devices rotatably supporting the first mold and the second mold on the first base structure and the second base structure, respectively,
• wherein the drive device is configured to rotate the first mold relative to the first base structure in order to rotate the first mold and the second mold coupled to the first mold when the first mold and the second mold are in a mold-closed state,
• wherein the drive device is configured to:
• rotate the first mold and the second mold about a central point, which is the central point of an entirety of the first mold and the second mold in the mold-closed state, and
• set the first mold and the second mold to a mold setting angle at which the first mold and the second mold are rotated,
• wherein the rotatable mold apparatus is configured to maintain the set mold setting angle while the first mold and the first base structure move together, and the second mold and the second base structure move together so that the first mold and the second mold open and close, and
• wherein the drive device comprises:
• a screw shaft horizontally disposed to be supported on the first base structure by a bracket, the screw shaft configured to receive a rotating force;
• a nut engaged with the screw shaft;
• a moving block fixed to the nut to move together with the nut;
• a guide rail disposed on the first base structure and parallel to the screw shaft, wherein the moving block is coupled to the guide rail such that a movement of the moving block is guided by the guide rail;
• and
• a pivot shaft disposed on the first mold, wherein the pivot shaft coupled to the moving block allows the first mold to rotate in response to the movement of the moving block.
