[0002] Pulp molding is a three-dimensional papermaking technology that uses waste paper as raw material and uses special molds on a molding machine to shape paper products of a certain shape. It is usually made by using a paper-plastic mold to shape and drain the initial embryo.

[0003] A Chinese patent discloses a paper-plastic mold that is easy to demould, and the publication number is CN219280367U. The handle is moved, and the movement of the handle drives the gear to move. The gear rotates under the action of the toothed plate, and the rotation of the gear drives the brush to rotate. The rotation of the brush cleans the bottom mold, which can achieve the purpose of easy cleaning, reduce the workload, and improve the efficiency of cleaning. When the top mold and the bottom mold are combined, the pressure rod moves during the top mold, and the movement of the pressure rod drives the movement of the cross rod, and the movement of the cross rod drives the movement of the hydraulic rod, so that the hydraulic rod drives the top block to move, so that the top block shrinks. When the top mold rises, the cross rod moves the hydraulic rod upward under the action of the first spring, and the upward movement of the hydraulic rod drives the top block to move upward to eject the product, which can achieve the purpose of easy demoulding, reduce the workload, improve the efficiency of demoulding, and avoid product damage.
