The invention discloses an investment casting device. The investment casting device comprises a working table, a liquid rising pipe and a heating furnace. The working table is arranged on the heating furnace. The heating furnace is composed of a heat insulating layer and a heating plate, and the heat insulating layer is arranged on the outer side of the heating plate. The working table is fixed to the heating plate, a dewaxing groove is formed between the working table and the heating table, and a model containing groove is formed in the upper end of the working table. A pair of rotating receiving frames are arranged on the two sides of the working table, a casting feeder head is formed in the middle of the model containing groove. The upper end of the liquid rising pipe is connected to the casting feeder head. A compressed air channel is formed in the working table. The investment casting device overcomes shortcomings in the prior art and is reasonable in design and compact in structure. The rotating receiving frames are arranged on the working table to receive materials back and forth, so that continuous liquid injection is guaranteed, the time for waiting for the working table is shortened, and the working efficiency is improved.
