Nonmetal acoustic baffle panel and preparation mould thereof

The utility model relates to a nonmetal acoustic baffle panel and preparation mould thereof. The utility model discloses a nonmetal acoustic baffle panel, panel are porous structure, and porous structure's pass is round frustum hole, round frustum hole's outer side hole footpath = 23 alpha hole pitchs, and is parameter alpha's value range 0.8 1.2, the hole pitch indicates the distance between adjacent outer side hole's the centre of a circle. The beneficial effects are that: through the relation between a large amount of experimental study round frustum hole apertures and the hole pitch for the technical scheme who prescribes a limit to can guarantee not influence under the circumstances of acoustic baffle panel noise resistance ability, reduces panel crackle rate, improves panel fracturestrength and shock resistance. The utility model discloses the mould structure who injects can reduce the drawing of patterns degree of difficulty of acoustic baffle preparation, improves productivity.
