Description

Technical Field

[0001] The present application relates to the technical field of forming molds, and in particular to a low-pressure paper trough forming mold. Background Art

[0002] The low-pressure paper slot forming mold is a mold that works under relatively low pressure. It is specifically designed and manufactured to ensure that the pulp or other materials are evenly distributed inside the mold under low pressure conditions. Inside the mold, the pulp is evenly distributed and filled into the slot structure under low pressure conditions. As the mold cools and solidifies, the pulp gradually solidifies into a product with a specific slot shape. This mold has the characteristics of low-pressure injection molding, namely, low injection pressure, good molding quality, and high product dimensional accuracy. Due to the use of low-pressure injection molding technology, the mold has a fast molding speed and can improve production efficiency. The existing molds have different internal shapes and irregular distribution of protrusions and depressions, which makes cleaning more troublesome. The raw materials may remain on the surface of the mold, making the mold rough and uneven, thereby affecting the accuracy and surface quality of the product. Utility Model Content
