Problems solved by technology
At present, in order to increase the operational flexibility of the spare tire cover, non-integral products gradually appear on the market, which are segmented products with a small width. However, due to the small width and large span, the traditional method has a cost advantage The segmented products produced by the advanced paper honeycomb wet spraying process have the problem of poor bearing performance, so it is urgent to solve the problem

Abstract
The invention discloses a production method of a trunk spare tire cover plate. The production method comprises the following steps of a, pre-burying: pre-burying a reinforcing sheet on a lower die of a forming die, b, material laying: laying a layer of first glass fiber felt on a workbench, laying a layer of paper honeycomb on the upper end surface of the first glass fiber felt, and laying a layer of second glass fiber felt on the upper end surface of the paper honeycomb to form a base material, c, spraying: uniformly spraying polyurethane on the base material, and d, forming: feeding the base material sprayed with the polyurethane into a forming mold where a reinforcing sheet is embedded to be formed so that the base material and the reinforcing sheet can be integrated, wherein the forming time ranges from 110 s to 130 s, the forming pressure ranges from 18 Mpa to 22 Mpa, the temperature of an upper forming mold ranges from 100 DEG C to 110 DEG C, and the temperature of a lower forming mold ranges from 95 DEG C to 105 DEG C. The L-shaped reinforcing sheets are pre-buried during forming, the reinforcing sheets are bonded through polyurethane during wet spraying forming, a whole is formed, and then the bearing performance of the product is improved.
Description
Technical field [0001] The present invention relates to the technical field of automotive interior parts, and in particular, to a method of producing a luggage storage. Background technique [0002] The car luggage storage cover is installed in the car luggage cabin, and the role of the baggage item and the spare tire below the partition. At present, in order to increase the operational flexibility of the spare tire cover, the non-film-type product has gradually occurred, which is a small width segmentation product, however, due to small width, large spacing, tradition has cost advantage The segmented product produced by paper honeycomb wet method, there is a problem of poor carrying performance, whereby urgent need to solve. Inventive content [0003] SUMMARY OF THE INVENTION An object of the present invention is to provide a method of producing a luggage storage cover for the above problems to solve the problems presented in the above background. [0004] It is achieved by the...
