Extrusion assembly of forming machine of gypsum plaster board and method of extrusion assembly

The invention discloses an extrusion assembly of a forming machine of a gypsum plaster board and a method of the extrusion assembly, and particularly relates to the technical field of forming machine assemblys.The extrusion assembly comprises a guide frame, a two-way transmission screw is installed in the guide frame, and the outer wall of the two-way transmission screw is sleeved with the extrusion assembly; the extrusion assembly comprises a first sleeving screw ring support arranged on the outer wall of the two-way transmission screw in a sleeving mode, and a second sleeving screw ring support is installed on one side of the first sleeving screw ring support. The extrusion assembly, the second side face attaching plate and the first side face attaching plate move relatively to fix the left side and the right side of the gypsum plaster board, in this way, during extrusion, left-right and front-back multi-face limiting operation on the gypsum plaster board can be achieved, extrusion deformation is avoided du
