Abstract

The invention discloses plant fiber molding manufacture equipment and a manufacture process thereof. The manufacture equipment comprises a former, wherein the former comprises a forming cover (1), a forming lower mold (2), a hot pressing upper mold (3) and a hot pressing lower mold (5) with a collecting disc (4); and an extruding upper mold (6) is arranged between the forming cover (1) and the hot pressing upper mold (3). The equipment has the advantages of simple structure and convenient operation, can be used to manufacture molding with greatly improved oil and water resistance so as to improve the service life of the molding.

Description

technical field [0001] The invention relates to plant fiber molding manufacturing equipment and a manufacturing process thereof. Background technique [0002] At present, the equipment commonly used in the manufacture of plant fiber molding includes a forming cover set on the forming machine, a forming lower mold, a hot-pressing upper mold and a hot-pressing lower mold with a receiving tray. The plants produced by such equipment Fiber molding has insufficient performance in terms of oil and water repellency, which reduces its service life. [0003] In the manufacture of plant fiber molding, the commonly used process includes forming, hot pressing and demoulding steps, the steps are as follows: (1), forming: under the action of the forming machine, the forming cover is lowered and pressed against the forming lower mold Above, the material enters the molding hood and the mold cavity of the lower molding mold through the feed port on the forming hood; the high-pressure gas ent...
