Pyrophyllite block compression molding device

The pyrophyllite block pressing forming device comprises a box body, a limiting assembly for pressing is arranged on the upper surface of the box body, the limiting assembly comprises a pressing bin, a pressing plate, a main spring, an auxiliary spring, a driving plate, a transmission strip, a driving gear and a positioning plate, and the inner side of the pressing bin is connected with the pressing plate; the pyrophyllite block does not press the pressing bin any more after pressing is completed, the pyrophyllite block is converted to press the positioning plate, the outer diameter of the auxiliary spring is smaller than that of the main spring, the elastic coefficient of the auxiliary spring is larger than that of the main spring, the positioning plate moves downwards under pressure to continue to extrude the auxiliary spring, and in the process, after the pressure borne by the pressing bin disappears, the auxiliary spring is pressed. The pressing bin does not apply pressure to the main spring any more, the
