Embodiment 1
[0033] refer to figure 1 and 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 t...

Abstract
The invention discloses a method for preparing an ambulance interior panel, and aims to provide a method for preparing an ambulance interior panel with low production cost, long service life and high strength. A layer of PMMA material layer is added on the basis of the material layer, and the melting layer between the ABS material layer and the PMMA material layer is kept in a good softening state through hot air treatment, and at the same time, the PMMA material layer and the ABS material layer are pushed by the wind pressure. Squeeze for a tighter connection. The present invention also relates to a preparation device for an ambulance interior trim panel. A cover plate is arranged above the mold frame, and a ventilation duct and a first air port are arranged on the cover plate, so that hot or cold air can enter and pass through the cover plate and the mold. The sheet blanks on the upper surface of the frame are in contact. The setting of the second air outlet enables hot air or cold air to be discharged alternately, which improves production efficiency.
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 ...
