The invention relates to the field of indoor geotechnical test of civil engineering, in particular to a parallel type electric rotary demolding method for demolding a cutting ring. In the parallel type electric rotary demolding method, a power mechanism, a demolding table and a demolding mechanism are involved. The power mechanism controls the demolding mechanism to rise up and fall down; a cutting ring test sample is fixed in a cutting ring fixing barrel of the demolding mechanism; the demolding table is arranged below the cutting ring fixing barrel; and when the demolding mechanism falls down, the demolding table can only block a test sample in the cutting ring test sample instead of blocking the cutting ring on the outer circle, so that the cutting ring can be separated from the test sample. After the above scheme is used, the problems of extremely large disturbance of the existing demolding equipment to the test sample in a demolding process, relatively low uniformity of demolded cutting ring and test sample, small one-time demolding quantity and the like are solved.
