Description

Technical Field

[0001] This utility model relates to the field of pulp mold technology, specifically a high-precision mold for pulp molding products. Background Technology

[0002] When producing pulp molded products, the mold is immersed in the pulp tank through a lifting structure. The raw materials in the pulp are adsorbed onto the mold mesh by vacuum. After the pulp is sucked and formed, the mold begins to rise.

[0003] However, a phenomenon called "slurry trapping" can occur, where the slurry absorption time is longer closer to the bottom area, resulting in uneven thickness of the product.

[0004] Therefore, we propose a high-precision mold for pulp molding products. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a high-precision mold for pulp molding products. After the pulp is sucked up, the mold is rotated 180° during the lifting process, so that the original "bottom" faces upward. Due to gravity, the excess pulp naturally flows back to the pulp pool, avoiding accumulation in the original bottom area, which can effectively solve the problems in the background technology.
