Manufacturing method and manufacturing production line of closed type refrigerator car heat preservation compartment plate

Abstract

The invention discloses a manufacturing method and a manufacturing production line of a closed type refrigerator car heat preservation compartment plate. The manufacturing method comprises the steps of compartment plate mold forming; forming a gel coat layer; molding the resin glass fiber structure layer; and mold closing, pressure maintaining, foaming and injection molding. According to the invention, the spraying of the profiling mold is combined with the foaming injection molding matched process, so that the profiling forming of the high-precision heat-insulating compartment plate is realized, the assembly precision of the heat-insulating compartment plate is improved, and the assembly difficulty of the heat-insulating compartment plate is reduced. The laminated composite technology combining spraying and foaming is adopted, the requirements for composite stability and structural strength can be met without adhesives, meanwhile, the laminated structure is improved, the material cost and the composite forming technology cost are reduced, and the formed heat preservation compartment plate is obvious in light weight advantage and easy to transport, carry and assemble. The preparation method is simple, reasonable and ingenious in step, and can meet the automatic circulating flow production requirement of the thermal insulation carriage plate by being matched with a manufacturing production line, so that the production efficiency is greatly improved, the production period is shortened, and the product uniformity and the qualification rate are guaranteed.

Description

technical field [0001] The invention relates to a production method and a production line for a closed-type refrigerated vehicle thermal insulation compartment panel, and belongs to the technical field of thermal insulation compartment panel manufacturing. Background technique [0002] The refrigerated truck is a special vehicle used to ensure the transportation temperature required for the transportation of goods in the refrigerated and refrigerated transportation of goods, and is a necessary transportation equipment for the cold chain distribution of goods. In the process of cold chain distribution of goods, according to the distance of cold chain distribution, cold chain distribution methods are mainly divided into two types, one is long-distance intercity cold chain distribution, and the other is short-distance intra-city cold chain distribution. In-city cold chain distribution is also known as "the last mile of cold chain transportation". At present, most large and medi...
