Disclosed are a thermoplastic automotive interior trim, and a preparation mold and a preparation method therefor. The preparation mold comprises an upper mold plate and a lower mold plate. The upper mold plate and the lower mold plate are oppositely arranged to form an inner mold cavity. The lower mold plate is provided with telescopic gas pins, and vacuum plastic-absorbing holes in communication with the inner mold cavity. The telescopic gas pins can extend into the inner mold cavity. According to the present invention, a thermoplastic automotive interior trim finished product can be prepared in one step by means of compression molding, preparation procedures are simple, the production efficiency is high, the preparation process is environmentally friendly, and there is no need to use an adhesive. The core material of the thermoplastic automotive interior trim is a foamed core material or a thermoplastic honeycomb-structured core material, thereby achieving the effect of being lightweight. The internal structure of the thermoplastic automotive interior trim can be freely designed, products of equal thickness or products of unequal thickness can be produced according to requirements, and a product folding function can be achieved by one-step mold pressing. The thermoplastic automotive interior trim can be recycled and reused, is light in terms of weight, and has a good sound insulation effect and a large bearing capacity.
