The invention provides a high-pressure vacuum vibratory forming machine and belongs to the field of building material high-density forming equipment. The high-pressure vacuum vibratory forming machineis characterized by comprising an outer rack, an inner rack, a base, a vibrator, a vibrating table, a pressing die, a pressing die, a pressing block, a first pressure machine, a second pressure machine and a vacuum chamber. The base, the vibrator, the vibrating table, the pressing die, the pressing block and the vacuum chamber are arranged in the inner rack. The vibrator is connected with the vibrating table which is installed on the base through a spring device. The pressing die is installed on the vibrating table. The pressing die is provided with a die cavity. The pressing block is locatedabove the pressing die. The pressing block is connected with a telescoping arm of a first pressure machine. The first pressure machine is installed on the top of the inner frame. A second pressure machine is installed on the outer rack and located above the first pressure machine. The vibrator comprises a vibrating motor. The vibrating motor is installed on the bottom of the vibrating table. An eccentric rotating wheel is installed on a motor shaft of the vibrating motor. The high-pressure vacuum vibratory forming machine can solve the problem that in the quartz plate pressing production process, pressure is insufficient, and the product quality can be effectively improved.
