the upper end and the lower end of the spiral coil 8 are fixed with the outer die 1, and the middle of the spiral coil 8 is attached to the outer die 1.
In the invention, the concrete block to be prepared has simple shape: if the cross-sectional shapes of the concrete blocks on all horizontal planes are completely consistent or the structure is large at the top and small at the bottom, firstly, the internal mold 2 with the shape made in advance is placed on the base plate 5, the air pump 7 is started to pump air into the lower groove 9, the air in the lower groove 9 can be communicated with the outside through the air outlet pipe 14, and when the air flows outwards from the lower groove 9, the groove plate 11 partially receives the reaction force generated by the outward outflow of the air, so that the upward acting force is applied to the groove plate 11 and the storage bag 12, and under the action of the acting force, the storage bag 12 is extruded to extrude the magnetorheological fluid in the storage bag into the liquid bag 4;
since the pipe diameter of the air inlet pipe 10 is greater than that of the air outlet pipe 14, that is, when the air pump 7 pumps air into the lower tank 9, the escape speed of the air in the lower tank 9 from the air outlet pipe 14 is lower than the pumping speed, so that the air bag 3 expands until the liquid bag 4 is tightly abutted against the inner mold 2, after the liquid bag 4 is completely wrapped and tightly abutted against the inner mold 2, current is introduced into the spiral coil 8, the current generates an obvious magnetic field on the liquid bag 4, and the magnetorheological fluid feels the action of the magnetic field and is converted into the property that the magnetorheological fluid cannot be deformed like a solid (when the magnetorheological fluid feels the magnetic field, the shear strength of the magnetorheological fluid rises in geometric progression, which is the known property of the magnetorheological fluid), and then the inner mold 2 is taken out.

The embodiment has wider application range and comprises a concrete block structure with multiple size changes from top to bottom, in the embodiment, after the air pump 7 works until the liquid bag 4 is tightly abutted against the inner die 2, the spiral coil 8 is electrified to convert the magnetorheological fluid in the liquid bag 4 into a solid state, then the power supply of the air pump 7 is disconnected to stop working, the spiral coil 8 is still in an electrified state, so that the shape of each liquid bag 4 is kept fixed, but the air bag 3 contracts under the elastic action of the air bag 3 to drive each liquid bag 4 to be far away from the inner die 2 and attached to the inner wall of the outer die 1, and the inner die 2 is easily taken out;
and after the internal mold 2 is taken out, the air pump 7 works again until the liquid bags 4 recover to be in a tightly and mutually abutted state, and then the concrete is poured into the space formed by the liquid bags 4 by the operation of the first embodiment until the concrete block is manufactured finally.
It is worth to be noted that when the concrete in the invention is solidified, the steel bars in the concrete and the spiral coil 8 jointly form an electromagnet, that is, the steel bars have a magnetism gathering effect to increase the surrounding magnetic field strength, thereby ensuring that the magnetic field strength of the magnetorheological fluid in the liquid bag 4 is larger and the solid property of the magnetorheological fluid is more obvious, and similarly, under the condition of ensuring a certain magnetic field strength, the current in the spiral coil 8 can be reduced, thereby achieving the effect of reducing energy consumption.
It is further explained that, when the concrete of the invention is solidified, the electricity communicated in the spiral coil 8 is changed into alternating current, and the alternating current can generate an alternating magnetic field at the reinforcing steel bar, so that the reinforcing steel bar generates an eddy current effect to generate a heating effect on the reinforcing steel bar, and especially in cold winter, when the environmental temperature is obviously lower than the optimum solidification temperature of the concrete, the concrete block can be heated by adopting the mode, and the manufactured concrete block is ensured to have good structural performance.
