Embodiment 1

[0011] Example 1: The production process steps of Wuhan Shenlong BX3 trunk lid trim are as follows:

[0012] Product specification: L1100×W550mm

[0013] 1. Material laying: the laying of materials is completed by the forming machine operator

[0014] 2. Compression molding: Use a 200-ton hydraulic molding machine to heat the above-mentioned laid materials in an oven and then press them into shape. When heating, the temperature of the heating plate of the upper oven: 300-310°C, and the temperature of the heating plate of the lower oven: 400-410°C , baking temperature time: 110±10sec; molding pressure: 5.0±0.5mpa, molding time: 80±5sec;

[0015] 3. Waterjet cutting: On the double-knife robot cutting system, the semi-finished product is cut by waterjet according to the specified cutting program, and the formed semi-finished product is cut by waterjet. The cutting water pressure is 40000-50000psi, and the cutting air pressure is 0.6-0.8mpa ; After the cutting is completed, remo...

Abstract

The invention relates to a method for producing a decorating part of a car boot cover, which belongs to the technical field of interior parts of cars. A low-density PP plate molding material is mainlyadopted as a decorating part basal body of a boot cover and is subjected to press molding, water-jet cutting and inspection to obtain a finished product. The invention solves the problem of meeting the performance indexes of sound absorption, heat resistance, light weight, high strength, and the like of a decorating part assembly of the boot cover and the three-grade international advanced level,greatly reduces the weight of the decorating part of the boot cover, meets the requirement on the lightweight design of the whole car and has stable molding process; a product has high rigidity and can not be broken and sagged; the product is produced by an automatic production line in the whole production process, thereby greatly reducing the labor intensity of workers in the production processand improving the production efficiency; no semi-finished product is stacked in the process, and the manufacture cost is saved; and the product does not generate harmful substances in the whole production process and belongs to an environmental-friendly product.

Description

technical field [0001] The invention relates to a production method of a decorative part of the trunk lid of an automobile, specifically for being installed at the rear of the automobile to play the role of heat insulation and beautification, and belongs to the technical field of automobile interior decorations. Background technique [0002] Car trunk lid decorations are generally installed at the rear of the car to play the role of heat insulation and beautification. In the era of more and more pursuit of high performance, environmental protection, energy saving, lightweight, and individualization, the interior of a car, like the shape of a car, has become an important factor for people to choose a car. Therefore, the requirements for automotive interior parts are getting higher and higher. In the prior art, performance indicators such as low weight and high strength of the trunk lid trim become bottlenecks, restricting the development of the trunk lid trim. Existing trun...
