Automobile plastic skylight manufacturing process

Abstract

The invention discloses an automobile plastic skylight manufacturing process which comprises the following steps: S1, checking raw materials, namely checking marks, quantity, appearance, color and the like of the raw materials, and checking an incoming material inspection report of the raw materials to ensure that the raw materials are correct and qualified and meet production requirements; s2, raw material warehousing: the qualified raw materials are fixedly placed according to warehouse requirements; s3, injection molding: stirring a completely molten plastic material through a screw at a certain temperature, injecting the completely molten plastic material into a mold cavity under high pressure, and cooling and curing to obtain a molded skylight, S4, trimming and molding, taking out the skylight, and trimming off redundant materials at a sprue, and S5, inspecting materials: inspecting whether the size, model, appearance, thread and the like of a nut meet quality requirements or not; and S6, assembling is conducted, specifically, the skylight is placed on a clamp, and a nut is assembled to the designated position in the skylight. The process of the automobile plastic sunroof is greatly simplified, the weight of the automobile plastic sunroof is reduced by 42%, the cost of the automobile plastic sunroof is reduced by 20%, and the net profit is increased by 20%.

Description

Technical field [0001] The present invention belongs to the field of automotive parts manufacturing technology, and specific relates to a car plastic skylight manufacturing process. Background technique [0002] Plastics are equally optimistic in the application prospects in the automotive industry. At present, many cars in the world have exceeded 120 kg / vehicle, and the individual models are high, and the plastic use of Mercedes-Benz high-end cars in Germany has reached 150 kg / vehicle. Plastics for some domestic cars have also reached 90 kg / vehicle. It is foreseeable that with the acceleration of the car lightweight process, the application of plastic in the automotive will be more extensive. Car light weight makes plastic as raw materials in the field of automotive parts, from the inner to the outernel and structural parts, the figure of the plastic parts is visible everywhere. At present, developed countries have used the amount of plastics for cars, as an important sign...

AI Technical Summary

Problems solved by technology

[0004] However, due to the structural characteristics of the car sunroof, the car sunroof is in a state of frequent movement and exposed to sunlight. Researchers have not been able to find a suitable solution for making the car sunroof "lightweight". The car sunroof adopts a metal structure, which will not only increase the weight of the vehicle, but also increase fuel consumption
