Description

Technical Field

[0001] The invention relates to the field of thermal insulation riser molding, in particular to a molding device for a flame retardant thermal insulation riser. Background Art

"The slurry is sucked away from the first suction pipe through the second capillary hole and then flows back into the pulp pool. The slurry that does not pass through the second capillary hole is adsorbed onto the surface of the second cylindrical mold. After the thickness of the slurry adsorbed on the surface of the second cylindrical mold reaches the requirement, the second cylindrical mold is turned up." The riser is formed by sucking the slurry. During the suction process, the slurry is adsorbed on the outside of the mold, resulting in a decrease in the ventilation of the mold, reducing the suction force on the slurry located on the periphery, and reducing the density of the slurry on the periphery, thereby affecting the overall uniformity of the riser, thereby affecting the yield rate after the riser is formed.
