Problems solved by technology

[0005] The current spare tire cover mainly adopts PP wood powder board, PP particle blow molding and other processes. The main problems are as follows: 1. PP wood powder board adopts hot material cold molding process. The weight is relatively high; 2. The PP particle blow molding process is complicated, the cost is high, and the weight is too heavy, which greatly increases the production cost and does not meet the economic benefits; 3. The product weight cannot meet the market's demand for reducing the weight of the car body

Abstract

The invention relates to a production technology for an automobile spare tire cover plate with a PP cellular board as a base material, and belongs to the technical field of automobile interior trim parts. The automobile spare tire cover plate with the PP cellular board as the base material is obtained through shell fabric preparation, shell fabric cutting, mold preheating, base material laying, pressing forming and postprocessing. The defects that existing spare tire cover plates are high in weight and not enough in rigidity are overcome, and the rigidity of the spare tire cover plate is improved, so that the bearing capacity of the spare tire cover plate is improved, and the weight of the spare tire cover plate is decreased so as to decrease the weight of an automobile body. Meanwhile, the production cost caused by the raw material cost is lowered. In addition, due to the fact that the production technology is simple, the rejection rate during production is lowered, raw materials are saved indirectly, and the cost for processing rejects is saved. The requirement of modern automobiles for high bearing capacity and low weight of the spare tire cover plate is met, the cost is low, the raw materials can be recycled, and the market consumption concept is met.

Description

technical field [0001] The present invention relates to a production process of automobile spare tire cover plate with PP honeycomb plate material as the base material. The PP honeycomb plate material is used to replace other materials such as PP plate of the old process, so as to increase the load capacity of the product and reduce the cost; specifically It is said that it is a production process of a spare tire cover plate for improving the rigidity of the spare plate in the trunk of the car and reducing the weight so as to increase the carrying capacity when carrying objects, and belongs to the technical field of automotive interior parts. Background technique [0002] The car spare tire cover is used as the partition layer between the spare tire and the storage in the car trunk. A platform for storage of slightly larger items and tools. Since the items stored in the trunk of a car are generally relatively large, and many of them are relatively heavy and large items, the...
