s3, demolding and taking out: after the step S2 is finished, the limiting effect of the positioning mechanism (4) on the forming mechanism (3) is removed, and the prepared heat-preservation cement product is taken out manually;

s4, cleaning and collecting: and (5) after the step (S3) is finished, manually sweeping the residual cement residues adhered in the equipment and on the surface of the heat-preservation cement product to obtain a heat-preservation cement product finished product.
