Embodiment 1

[0040] Example 1 A car spare tire cover

[0041] Such as figure 1 As shown, the automobile spare tire cover plate of the present embodiment is a three-layer composite layer structure along its thickness direction, including a mixture layer 2 of rigid polyurethane and fiber formed by high-pressure foaming and spraying as the core, and a high-pressure foaming spray-molded mixture layer 2 respectively. The first hard polyurethane surface layer 1 and the second hard polyurethane surface layer 3 are formed by foaming and spraying on both sides of the core. in,

[0042] The fiber is glass fiber (it can also be hemp fiber, man-made fiber or synthetic fiber, or a mixture of two or more of glass fiber, hemp fiber, man-made fiber and synthetic fiber, depending on the type of fiber in this case) equipped with a corresponding number of fiber cutters).

Embodiment 21—27

[0043] Embodiment 21-27 A kind of processing technology of automobile spare tire cover plate

[0044]

[0045]

[0046]Embodiments 21-27 are respectively a process for processing the spare tire cover of an automobile, which are used to process the product of Embodiment 1. They are carried out in the following order respectively:

[0047] ①Use a high-pressure foaming machine to spray the rigid polyurethane at 22-28°C to the lower mold of the mold to form the first rigid polyurethane surface layer 1 with a gram weight of 200-500g / m 2 ;

[0048] ② The rigid polyurethane at 22-28°C is sprayed onto the first rigid polyurethane surface layer 1 with a high-pressure foaming machine, and the chopped fibers are sprinkled at the same time, so that the rigid polyurethane and the fibers are fully infiltrated or partially soaked when spraying. Infiltration, after reaching the first hard polyurethane surface layer 1, it is completely infiltrated (the final realization of full infiltr...

Embodiment 3

[0058] Embodiment 3 A kind of processing equipment of automobile spare tire cover plate

[0059] The processing equipment of the present embodiment is used for processing the product of embodiment 1, and its work process can realize the technology of embodiment 21-27.

[0060] The present embodiment comprises mechanical arm 4 under main program control, two fiber cutting machines 51 and 52 (sprinkle into one or two kinds of fibers and join two; If want to spread into more kinds of fibers at the same time, then need to be equipped with corresponding number fiber cutting machine), high-pressure foaming rigid polyurethane spraying machine, mould, molding press and mold temperature controller, among which:

[0061] The two fiber cutting machines 51 and 52 are independent devices, and have bolts for connecting external devices, so that the installation angle can be adjusted freely.

[0062] The two sides of the spraying head 6 respectively located in the high-pressure foaming rigi...

Abstract

The invention discloses an automobile spare tire cover plate and a processing process and processing device thereof. The automobile spare tire cover plate is of a compound layer structure in the thickness direction and comprises a mixture layer of rigid polyurethane and fiber, a first rigid polyurethane surface layer and a second rigid polyurethane surface layer, wherein the mixture layer is formed by high-pressure foaming spraying molding and serves as a core part, and the first rigid polyurethane surface layer and the second rigid polyurethane surface layer are formed on two sides of the core part by high-pressure foaming spraying molding. According to the automobile spare tire cover plate, the thermosetting rigid polyurethane material is adopted, and high-temperature dimensional stability of the product is guaranteed after forming; in addition, the manufactured product is light and high in strength; the processing process guarantees that the product is not subject to the layered risk, product integration is achieved, the surface of the product is flat, the problem of fiber outleakage is solved, the process can achieve low VOC discharge, discharge of harmful substances in an automobile is reduced, and the riding environment in the automobile is improved; the processing device is high in automation degree, normal production can be achieved through one person, the process is simple, labor is saved, and the processing cost is reduced. The automobile spare tire cover plate is suitable for various automobiles.

Description

technical field [0001] The invention belongs to the field of automobile interior panels, and relates to an interior decoration panel for the interior of an automobile trunk, in particular to an automobile spare tire cover and its processing technology and processing equipment. Background technique [0002] The car spare tire cover product is installed in the trunk of the car, used to separate the spare tire compartment and the trunk, and plays the role of covering the spare tire, on-board tools and carrying the contents of the trunk, and the surface state plays the role of decorating the trunk effect. [0003] The existing spare tire cover materials mainly include PP injection molding, PP honeycomb board, PP wood powder board (including hollow blowing method), hard fiberboard, etc. Among them, PP injection molding and PP honeycomb board have poor heat resistance, and PP material The softening temperature is 90-95°C, and the strength performance decreases at high temperature...
