The invention provides a grain pressing and demolding device of a five-beam four-column oil press, which comprises an oil press main body (1), a grain mold body (4) is arranged on the oil press main body (1), an upper punch (4a) is arranged in the grain mold body (4), and a pressing and demolding module correspondingly matched with the grain mold body (4) is arranged on the oil press main body (1). The hydraulic press is characterized in that a lower die groove (8) distributed corresponding to the grain die body (4) is formed in the hydraulic press body (1), an adjusting backing ring (9) is connected to the lower die groove (8), and a grain returning device assembly (11) is arranged on the lower die groove (8). The device is simple in structure and convenient to use, the adjusting frequency of the die cushion block is reduced, the pressing stroke is convenient to adjust when a grain is pressed, and the grain forming consistency is better; the device can press the grain in one direction, and the grain pressing
