Embodiment 1

[0033] refer to figure 1 with figure 2 , the invention provides a kind of preparation method of ambulance trim panel, specifically comprises the following steps:

[0034] S1. A double-layer co-extrusion process is adopted to obtain a sheet blank 7, the upper surface of the sheet blank 7 is a PMMA material layer 702 with a thickness of 0.5 mm, and the lower surface is an ABS material layer 701 with a thickness of 5 mm;

[0035] S2. Cut the blank 7 to the corresponding size as required, then fix the blank 7 on the fixture, and move it to a high-temperature furnace for heating. The heating temperature is 150 degrees Celsius, and the heating time is 15 minutes to ensure that the blank 7 is completely softened;

[0036] S3. Move the plate to the top of the mold frame 1, and make the edge of the plate fit the edge of the mold frame 1, so that a sealed environment is formed between the plate and the mold frame 1;

[0037] S4, start the air pump to form a negative pressure between ...

Abstract

The invention discloses a preparation method for an ambulance interior trimming panel. According to the preparation method for the ambulance interior trimming panel, the production cost is low, the service life is long and the strength is high. According to key points of the technical scheme, a PMMA material layer is additionally arranged on the basis of an ordinary ABS material layer, a melting layer between the ABS material layer and the PMMA material layer is kept in a good softening state through hot air treatment, and meanwhile, the PMMA material layer and the ABS material layer are connected more tightly through the pushing-extruding effect of the air pressure. The invention further relates to a preparation device for the ambulance interior trimming panel. A cover plate is arranged on the upper part of a mold frame, a ventilation pipeline and a first air opening are formed in the cover plate, thus hot air or cold air can enter a plate blank penetrating through the upper surfacesof the cover plate and the mold frame and make contact with the plate blank, while through forming of a second air opening, the hot air or the cold air can be discharged alternately, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a method for preparing an ambulance interior trim panel, and also to a preparation device for an ambulance interior trim panel. Background technique [0002] Ambulances are refitted on the basis of ordinary passenger cars. There are two types of interior applications for ambulances. One is to use the interior of the original passenger car, and the other is to replace it with ABS materials. Or interior made of composite fiberglass. The original passenger car interior has the disadvantages of being not waterproof, easy to age, and breeding bacteria due to its fabric composition, which is not suitable for modern ambulance. decorated. [0003] However, due to the process characteristics of composite FRP, the quality of the mold is high, especially when the size is large, the cost of the mold is often difficult to bear. In addition, there are no mature measures to deal with and ...
