Problems solved by technology

[0002] At present, if the traditional PP wood powder board is used to make the rear shelf of the car, if the load-bearing requirements are to be improved, the gram weight of the PP wood powder board needs to be greatly increased to meet its rigid load-bearing requirements, so that the cost rises greatly, and the gram weight After rising to a certain level, its carrying capacity can no longer rise

Abstract

The invention relates to a production method of manufacturing a rear shelf of an automobile by using a PP (Polypropylene) wood flour plate. The production method comprises the following steps of: spreading and drying, i.e., spreading a first PP wood flour plate on a lower die mold, and piercing with a gas blowing needle, i.e., piercing the first PP wood flour plate with the gas blowing needle; stacking a second PP wood flour plate above the first PP wood flour plate and the tip of the gas blowing needle; spreading a surface material of the rear shelf on the upper surface of the second PP wood flour plate; performing press forming, gas blowing forming and cooling forming; and taking a semi-finished product of the rear shelf out and performing cooling forming at room temperature to obtain a rear shelf finished product. According to the production method, the bearing performance of a product is increased without increasing the weight of the material, and the production cost is also reduced.

Description

technical field [0001] The invention relates to a manufacturing process of automobile interior parts, in particular to a production method of using PP wood powder boards to manufacture automobile rear shelves. Background technique [0002] At present, if the traditional PP wood powder board is used to make the rear shelf of the car, if the load-bearing requirements are to be improved, the gram weight of the PP wood powder board needs to be greatly increased to meet its rigid load-bearing requirements, so that the cost rises greatly, and the gram weight After rising to a certain level, its carrying capacity can no longer rise. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a production method of using PP wood powder boards to manufacture automobile rear shelves, which can improve the load-carrying performance of products and reduce production costs. [0004] According to the technical sc...
