Material spraying tube moving device for surface spraying of glass fiber reinforced plastic mold

Abstract

The invention discloses a material spraying tube moving device for surface spraying of a glass fiber reinforced plastic mold. The material spraying tube moving device comprises a circular tubular material tube, an angle adjusting assembly and a height adjusting assembly, wherein the angle adjusting assembly and the height adjusting assembly sleeve the outer part of the material tube; the angle adjusting assembly comprises an upper plate, a top ring, a gear cylinder, a vertical tube, a rod base, a worm, a lower plate, a transmission column and an angle motor; the height adjusting assembly comprises a triangular screw tube, a height motor and a limiting cylinder; an upper middle hole is formed in the middle of the upper plate; four upper edge holes distributed in a rectangular array are formed in the upper plate; upper wall holes are formed in the side wall of the upper plate; the lower plate is located right below the upper plate; a lower middle hole is formed in the middle of the lower plate; three lower edge holes distributed in a ring array are formed in the outer side of the lower middle hole; and two groups of base threaded holes are further formed in the upper surface of the lower plate. The material spraying tube moving device for surface spraying of the glass fiber reinforced plastic mold can replace a Z-axis and spindle rotating assembly of an existing automatic spraying machine and is suitable for being widely popularized and used.

Description

technical field [0001] The invention belongs to the technical field of mold manufacturing, and in particular relates to a material spraying pipe moving device used for spraying the surface of a glass fiber reinforced plastic mold. Background technique [0002] FRP, the scientific name is glass fiber reinforced plastic, referred to as FRP, generally refers to the use of glass fiber to reinforce thermosetting resin, unsaturated polyester, epoxy resin and phenolic resin as the matrix, and glass fiber or carbon fiber as reinforcement Reinforced plastics. [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 additio...

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 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.
