[0017] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative efforts are within the scope of the present application.

[0018] Please refer to Figures 1-4 The present application provides a technical scheme: a automobile interior part mold convenient for demolding, which comprises a bottom plate 1 and a lower mold 2, the lower mold 2 is fixed on the bottom plate 1 through bolts, a movable plate 3 is arranged between the bottom plate 1 and the lower mold 2, one end of a spring 301 is fixed on the movable plate 3, the other end of the spring 301 is fixed on the lower end face of the lower mold 2, a sliding rod 302 is also fixed on the movable plate 3, and the sliding rod 302 is in sliding connection with the lower mold 2, and a plurality of ejector pins 303 are also uniformly fixed on the movable plate 3, and the ejector pins 303 are in sliding connection with the lower mold 2.
