PURPOSE: A vacuum press is provided to restrict rotation of a rod by fixing an upper rod of a cylinder with an interlock guide rod in assembling an injection plate, and to prevent forming material from bubbling by a leakproof vacuum box with the packing of the rod. CONSTITUTION: A rod of a transfer cylinder(20) is protruded up and down, and fixed in an upper fixing plate(11). An upper rod(22) is connected to an interlock guide rod(15) fixed in the upper fixing plate through a cross fixing bar(16). Upper and lower rods(22,22-1) are guided, and a fuel injection port(23) is fixed in the end of the lower rod firmly. A T-shaped packing pipe(10) is sealed in a ram(9) in a periphery of the lower rod. A slide hole is formed in a driving plate(31) connected to a guide rod(13), and a transfer rod(34) supported by a repulsive spring is connected closely by packing. A transfer screw rod(35) is protruded in a lower plate(11-1) in a straight line. The forming material in a forming hole(14) is pushed up with moving up the transfer rod contacted to the transfer screw rod in moving the driving plate down.
