A spray pipe moving device for surface spraying of glass fiber reinforced plastic molds

Abstract

The invention discloses a material spray pipe moving device used for spraying the surface of a glass fiber reinforced plastic mold, which comprises a circular tubular material pipe and an angle adjustment assembly and a height adjustment assembly sheathed on its outside, the angle adjustment assembly includes an upper plate, a top Ring, gear cylinder, standpipe, rod seat, worm, lower plate, transmission column and angle motor, the height adjustment assembly includes a triangular screw, a height motor and a limit cylinder, and an upper middle hole is opened in the middle of the upper plate, The upper plate is provided with four upper holes distributed in a rectangular array, the side wall of the upper plate is provided with upper wall holes, the lower plate is located directly below the upper plate, and the middle part of the lower plate is provided with a lower middle hole. There are three lower edge holes arranged in an annular array on the outer side of the lower middle hole, and two pairs of seat threaded holes are arranged on the upper surface of the lower plate. The spray pipe moving device used for spraying the surface of the glass fiber reinforced plastic mold can replace the Z-axis and the main shaft rotating assembly of the existing automatic spraying machine, and is suitable for popularization and use.

Description

technical field [0001] The invention belongs to the technical field of mold manufacturing, and in particular relates to a spray pipe moving device used for spraying the surface of a glass fiber reinforced plastic mold. Background technique [0002] FRP, scientific name is glass fiber reinforced plastic, referred to as FRP, generally refers to the use of glass fiber to strengthen the thermosetting resin, with unsaturated polyester, epoxy resin and phenolic resin as the matrix, with glass fiber or carbon fiber as the reinforcement. [0003] In order to ensure the production quality of FRP, the mold needs to be pretreated before molding. In the pretreatment method, the surface of the mold is sprayed with gel coat. When spraying the gel coat, it is necessary to keep the distance between the nozzle and the mold within the range of 300-400mm, and In order to ensure uniform spraying during spraying, the nozzle needs to maintain a vertical angle to the mold in addition to moving at ...

[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 the range of 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. The common solution is to use a spraying machine for spraying. The vertical adjustment range of the existing spraying machines is small, and most of them use linear modules or electric motors. The guide rail is used for driving. The motor of this driving scheme needs to adopt a larger heat dissipation scheme, and the overall structure is relatively bloated.
