Manufacturing method of driver fence rear enclosure and manufacturing method of driver fence driver door

Abstract

The invention discloses a manufacturing method of a driver fence rear enclosure and a manufacturing method of a driver fence driver door. The manufacturing method of the rear enclosure comprises the steps of 1) preparing a mold, and specifically, manufacturing a foaming mold meeting requirements according to the shape and structure requirements of the rear enclosure; 2) selecting a surface material and placing the surface material in a lower mold body, and adsorbing or suspending and tensioning an inner surface base material on the surface of an upper mold body; 3) laying a reinforcing material layer zone 1b in the lower mold body of the mold, so that the reinforcing material layer zone 1b is large in density and high in strength; 4) injecting a polyurethane foaming material through high-pressure foaming, assembling the upper mold body and the lower mold body, carrying out maintaining pressure and curing, and completing integral forming of the rear fence; and 5) taking out of a productafter the product is cured, and carrying out edge cutting and trimming. For the manufacturing method of the driver door, the manufacturing method is the same, and a different mold is used. The overall structure is simple, the assembly efficiency is high, the final assembly time is 67% of that of a split structure product, the number of assembly parts is small, no gap exists, the strength is high,stability is achieved, no abnormal sound exists, the inner surface and the outer surface are formed in place at a time, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of passenger car interior parts, in particular to a method for making a driver's rear enclosure and a driver's door. Background technique [0002] At present, the driver's enclosure of the bus is mostly made of splicing aluminum profiles or pasting glass and steel. Regardless of whether it is a glass fiber reinforced plastic surround or an aluminum alloy driver surround, the traditional driver surround products generally include three major components: the rear gear, the rear corner, and the driver's door. The fiberglass driver enclosure adopts resin manual pasting process, the production cycle is long, it cannot be mass-produced, and the environmental protection is not up to standard, so it has been eliminated by the industry. The aluminum profile is limited by the molding size of the mold, and the aluminum alloy enclosure is mostly spliced ​​by smaller profiles, plastic sheets, glass and other materials, ...

The fiberglass driver enclosure adopts resin manual pasting process, which has a long production cycle and cannot be mass-produced, and the environmental protection is not up to standard, so it has been eliminated by the industry

The aluminum profile is limited by the molding size of the mold, and the aluminum alloy enclosure is mostly spliced ​​by smaller profiles, plastic sheets, glass and other materials, such as the Chinese patent CN201720531781. Surroundings are all assembled from multiple parts. There are gaps in the assembly parts and many connectors. After a long time of use, they are easy to loosen and produce abnormal noises, which poses a safety risk; drivers spliced ​​​​by aluminum alloy small profiles, plastic plates, glass and other materials Surrounding, the construction procedure is complicated, the construction time is long, and the cost is high; various body and air duct sizes and shapes make it difficult to match the size and shape of the top of the driver's surround rear wall, and it is not easy to install. Generally, the following methods are adopted: 1. According to the different sizes and shapes of the air ducts, different molds are used to make the size and shape of the top surrounded by different air ducts to match different air ducts, which is convenient for installation. This method requires many molds and high production costs; According to the different sizes and shapes of the air duct, the top of the enclosure is cut to avoid the air duct. The edge of the top of the enclosure is exposed. Because the edge is close to the air duct, it is inconvenient to wrap the decorative profile. The top of the enclosure is suspended and not fixed. When the body vibrates, Low strength, poor stability, and abnormal noise around the top cutting edge
