Description

Technical Field

[0001] This utility model relates to the field of grating production technology, and in particular to a hydraulic drive mechanism for rapid demolding of molded gratings. Background Technology

[0002] Molded grating is a sheet material with a regular opening ratio, made of unsaturated polyester resin as the matrix and glass fiber roving as the skeleton, and manufactured on a customized mold through a special process. Molded grating has advantages such as corrosion resistance, flame retardancy, anti-slip properties, aging resistance, and easy maintenance. Therefore, molded grating is widely used in working platforms, equipment platforms, drilling platforms, walkways, etc. in industries such as petroleum, chemical, electronics, power, paper, printing and dyeing, electroplating, marine exploration, and sewage treatment. At the same time, it is also suitable for civil building facilities, such as stair treads, ditch covers, and bridge decks. After the molded grating is hot-pressed, the product needs to be demolded from the mold. However, most existing demolding methods are done manually by workers, which is slow and reduces the production efficiency of the grating. In view of this, this utility model is proposed. Summary of the Invention
