[0002] A pallet is a horizontal platform device used for packaging, stacking, handling and transporting goods and products as unit loads. As a type of packaging equipment similar to containers, pallets are now widely used in production, transportation, warehousing and circulation, and are considered to be one of the two key innovations in the logistics industry in the 20th century. As a tool for stacking and handling goods, pallets are movable cargo platforms and important logistics equipment. They play an irreplaceable role in the fast and efficient modern industrial and commercial logistics system, and have broad market prospects in my country. Most of the pallets currently in use are prepared by hydraulic forming. The molding of logistics pallets has a history of many years, but traditional hydraulic devices are mostly single-layer hydraulics. Such hydraulic methods are limited to the pressing method in a single direction, and their products are always single-layer structures. Molded logistics pallets always have only one style, single-sided nine-legs, or the product is first pressed into a single-sided accessory by a hydraulic device and then the different single-sided accessories are assembled into a double-sided panel. This results in low preparation and processing efficiency, and the final product has poor structural stability and is inconvenient to use. Therefore, it is very important to provide a multi-directional molding equipment that can be used for one-time molding of double-layer pallets. Summary of the invention
