According to the present invention, a vacuum molding apparatus includes: a main body frame; a moving means which is formed on the main body frame to allow a sheet to be mounted thereon and to be moved; a clamp means which is arranged on an upper side of the moving means and presses and supports an edge of the sheet; a heating means which heats the sheet transferred by the moving means; and a molding means which molds the heated sheet, supported on the moving means by the clamp means, into a molded product in a relevant shape. The clamp means includes: an installation frame installed on an upper side of a mounting frame of the moving means; a pressing and supporting bar which is pivotally located on an upper side of the mounting frame and presses, supports, and releases the edge of the sheet; and a pivotal actuator which is connected to the pressing and supporting bar while being installed on the installation frame, receives compressed air to be extended or contracted, and enables the pressing and supporting bar to support the sheet (S) by making the pressing and supporting bar pivot or return to an original position. |
