[0029] In this embodiment: It should be noted that in the initial state, the lifting plate 6 is at the lowest point.

[0030] When the staff uses the feeder to feed the material into the upper storage box of the core making machine, the staff first moves the coated sand bag to the side of the lifting plate 6, and then tilts the coated sand bag and places it flat in the middle of the deflection plate 7;

[0031] When the coated sandbag is placed on the deflection plate 7, the coated sandbag applies downward pressure to the slider 21, and the slider 21 moves downward along the first slide groove 14.
