The invention relates to a quality control method for molding wall and floor bricks. The quality control method comprises the following steps: (1) molding: before the press molding, measuring and controlling pressure and punching frequency of a pressing machine, sampling a green brick pressed on each pressing machine regularly, and detecting a molding thickness and weight of the green brick; (2) drying: drying the green brick in a drying kiln, regularly detecting a drying temperature and operation condition of the drying kiln, and measuring and controlling the technological parameters of the dried green brick; (3) glazing: glazing and printing the dried green brick, and regularly detecting the temperature of the green brick before the printing and the glaze amount of a glaze spraying cabinet; (4) firing: firing the green brick at a high temperature to obtain a semi-finished product brick, regularly measuring and controlling the firing technological parameters, and detecting the technological parameters of the semi-finished product brick at the tail of the kiln; and (5) polishing: detecting the technological parameters of the semi-finished product brick again, polishing to obtain the wall and floor bricks, and regularly detecting the polishing cutting amount. By adopting the method, the quality of the green brick can be more precisely controlled, the rejection rate is low, and the production quality is improved.
