PURPOSE: To provide an apparatus for fixing blank material of mold press for automobile armoring to obtain stable bending conditions of the blank material for automobile armoring, uniformly bend the blank material, prevent damage of the blank material, reduce production of defective products and seek safety of workers. CONSTITUTION: The apparatus comprises a hydraulic pressure supply unit (2) for supplying hydraulic pressure to one side of the mold press (1); a fixing unit (3) comprising a hydraulic cylinder (31) installed at one side of lower die with being connected to a hydraulic pressure supply pipe (21) from the hydraulic pressure supply unit, a cylinder shaft formed at one side of the hydraulic cylinder, a sheet type moving bar (32) on which a shaft insertion hole is formed so that the cylinder shaft is inserted into the shaft insertion hole, a moving element formed on a lower part of one side of the moving bar, a fixing pin inserted into a fixing pin insertion hole to fix the moving bar and the cylinder shaft to a shaft insertion hole formed on the moving bar, and fixed rails (33) slidingly inserted onto the moving element with both sides of the moving element of the moving bar being covered by the fixed rails; a pressure sensor (51) inserted into a central part of the cylinder shaft; movement sensor (52) and action sensor (53) formed on an upper die; a check sensor (54) formed on a lower die; and a control panel (5) on an upper part of which pressure indicator (511) and hydraulic pressure indicator (312) for controlling the respective sensors and the hydraulic pressure supply unit are installed, wherein the sensors and the control panel are organically connected to each other.
