The present invention discloses a hollow one-time molding mold for an automobile seat headrest, comprising a left bottom plate connected with one end of a left cavity plate through a left cushion block, the other end of the left cavity plate is connected with one end of a right cavity plate, the other end of the right cavity plate is connected with a right bottom plate through a right cushion block, the lower surfaces of the left cavity plate and the right cavity plate are connected with a headrest framework fixing plate through groove tubes, a headrest cavity is formed between the left cavity plate and the right cavity plate, and cooling water channels are arranged around the left cavity plate and the right cavity plate. The present invention has a simple structure, is safe and reliable, and is suitable for producing hollow plastic products of thermoplastic materials. Parts contained in the automobile headrest can be molded at one time by blow molding through a positioning tool, and high-quality and high-strength integrated seat headrests can be produced, which are not easy to damage, eliminating part of the worker assembly processes. It avoids cumbersome and error-prone assembly steps, shortens the production cycle of products, improves production efficiency, reduces costs and improves product quality.
