Embodiment 1

[0022] Produce Dongfeng passenger car EJ02 integrated front carpet, its specification is: length 1200×width 620mm.

[0023] The production method of the integrated automobile carpet comprises the following steps:

[0024] (a) Placement of shock-absorbing pad raw materials: according to the thickness of each area of ​​the car carpet, lay the corresponding thermoplastic cotton felt at the corresponding position of the lower mold;

[0025] (b) Baking temperature of shock-absorbing pad raw materials: Send the lower mold with thermoplastic felt into the hot air box through the chain transmission mechanism for heating. 550~650 seconds;

[0026] (c) Compression molding: The heated lower mold with thermoplastic felt is sent into the molding machine, and the upper mold of the molding machine is pressed down, so that the upper mold and the lower mold of the molding machine are cooled and shaped, and formed The pressure is controlled at 6~10Mpa, the molding time is controlled at 400~50...

Abstract

The invention discloses a production method of an integrated car carpet. The production method comprises the steps of laying of shock pad raw materials, drying of the shock pad raw materials, compression molding, laying of a surface carpet and a semi-finished product of shock pad below the carpet, drying of the surface carpet, fit molding, water cutting and the like. The integrated car carpet produced by the method disclosed by the invention meets the requirements of performance index, such as vibration reducing, environment protecting and lightening; the weight of the integrated car carpet is greatly reduced, and the requirement of the whole car lightening is met; the cost of raw materials is reduced due to the selection of thermoplastic felt and a PET and EVA compounded surface carpet, so that the selectivity is high; in the process of material processing, a hot air box is adopted for heating, a mold is adopted for compression molding, a water jet scalpel is adopted for cutting, the technology is stable, the safety and the accuracy of the operation are ensured, and the working efficiency is improved; excess materials of the product are less; no semi-finished products are stacked in the process, and the manufacturing cost is reduced; and no harmful substance is generated in the whole production process of the product.

Description

technical field [0001] The invention discloses a production method of an integrated automobile carpet, which belongs to the technical field of production of automobile parts. Background technique [0002] The car integrated carpet is installed above the car floor, which plays the role of heat insulation, shock absorption, noise reduction, sound absorption and vehicle weight reduction. 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 existing technology, performance indicators such as high sound absorption, low weight, strong heat insulation, shock absorption, recyclability, and environmental protection of integrated carpets have become bottlenecks, restricting the development of integrated a...
