A rail vehicle fiberglass seat mold

Abstract

The invention discloses a glass fiber reinforced plastic seat mold for a rail vehicle, which comprises a seat back mold for forming the lower layer of the seat and a seat surface mold for forming the upper layer of the seat; The chair back male mold and the chair back female mold of the inner cavity; the chair surface mold includes the chair surface male mold and the chair surface female mold of the inner cavity part having the same shape as the upper layer of the seat after being closed; the chair back male mold is provided with a chair back mold. Strip grooves, and / or chair surface strip grooves are arranged on the chair surface female mold. In the fiberglass seat mold disclosed by the present invention, the upper layer of the seat is molded separately from the lower layer of the seat, and strip-shaped grooves are arranged on the male mold of the back of the chair and / or the female mold of the seat surface. Improve the strength of the chair, solve the mass production of fiberglass seats, improve production efficiency, and reduce the weight of the seat.

Description

technical field [0001] The invention relates to the field of vehicle engineering, and more specifically, relates to a glass fiber reinforced plastic seat mold for rail vehicles. Background technique [0002] With the rapid development of urban construction, more and more cities have light rail, subway and other convenient means of transportation. As a part of urban infrastructure, urban rail vehicles such as light rail and subway are playing an indispensable role. [0003] At present, the main material of the seats of urban planning vehicles is FRP. The main characteristics of FRP are light and hard, non-conductive, high mechanical strength, corrosion resistance, etc., which can replace various mechanical parts and automobile shells of steel supports. Mainly through hand lay-up, vacuum forming and other production processes. FRP seat hand lay-up process has disadvantages such as low production efficiency, poor surface quality and product identity. Modules cannot be interchan...

AI Technical Summary

Problems solved by technology

Mainly through hand lay-up, vacuum forming and other production processes. FRP seat hand lay-up process has disadvantages such as low production efficiency, poor surface quality and product identity. Modules cannot be interchanged when the handle on the seat is in different positions. A chair requires a set of molds, and the curing of the resin and the later surface polishing consume a lot of manpower and material resources

At the same time, the hand lay-up process requires the use of a large amount of organic solvents, which will cause harm to the health of workers and cause environmental pollution.

Generally, the strength of the seat is achieved by pre-embedding the metal skeleton, which increases the weight and the risk of the bonding performance between the metal and the resin gradually decreasing over time
