Die surface treatment device with even spraying function and for production of glass fiber reinforced plastics

Abstract

The invention relates to a die surface treatment device with an even spraying function and for production of glass fiber reinforced plastics. The die surface treatment device comprises a supporting mechanism, a platform, a spraying head, a testing mechanism, a fastening mechanism and a planar moving mechanism, the supporting mechanism comprises a plurality of supporting assemblies, and the supporting assemblies comprise first motors, first driving shafts, sleeves, driving rods, supporting rods and hinges blocks; and the fastening mechanism comprises an air cylinder and a plurality of fasteningassemblies, and the fastening assemblies comprise air tubes, air cylinders, pistons and fastening blocks, and the testing mechanism comprises a plurality of testing units. According to the die surface treatment device with the even spraying function and for production of the glass fiber reinforced plastics, a die is fastened from different directions through the fastening mechanism, the situationthat shaking of the die in the spraying process affects the spraying effect is prevented, not only that, the angle of the platform is adjusted through the supporting mechanism, so that the die on theplatform is kept in the angle perpendicular to the spraying head, therefore a rubber coat is advantageously and evenly attached to the surface of the die in the spraying process, the spraying effectis improved, and the practicability of the device is improved.

Description

technical field [0001] The invention relates to the field of new material equipment, in particular to a mold surface treatment device with uniform spraying for producing glass fiber reinforced plastics. Background technique [0002] FRP, the scientific name is glass fiber reinforced plastic, the English full name is Fiber Glass Reinforced Plastic, referred to as FRP, generally refers to the use of glass fiber to strengthen thermosetting resin, with unsaturated polyester, epoxy resin and phenolic resin as the matrix, glass fiber or carbon fiber Reinforced plastic for reinforcement. The FRP molding process generally includes hand lay-up molding, RTM molding, compression molding, winding molding, pultrusion molding, spray molding, etc. Among them, the compression molding method is to install the mold on the press, and the materials The cavity is heated and pressurized to make it solidify and form. [0003] In order to ensure the production quality of FRP, the mold needs to be...

AI Technical Summary

Problems solved by technology

[0003] In order to ensure the production quality of FRP, the mold needs to be pretreated before molding. In the pretreatment method, the gel coat is sprayed on the surface of the mold. When spraying the gel coat, it is necessary to keep the distance between the nozzle and the mold within 300-400mm, and In order to ensure uniform spraying during spraying, the nozzle needs to maintain a perpendicular angle to the mold in addition to moving at a constant speed. At present, people usually use spray guns for manual spraying. In the spraying process, affected by various factors, the spray gun and the mold are prone to shake. The distance between the spray gun and the mold surface is also in an unstable change, and it is difficult to ensure that the angle between the spray gun and the mold is perpendicular, which in turn reduces the quality of gel coat spraying and affects the subsequent production of FRP
