The invention discloses an automobile body cavity sound insulation rubber block. The automobile body cavity sound insulation rubber block includes a sound insulation substrate, installation clamping buckles arranged at the lower surface of the sound insulation substrate, a guide tube of which the outer wall is connected with the sound insulation substrate, a plugging cover, and a foam material which is embedded at the circumference of the sound insulation substrate, wherein the guide tube passes through the sound insulation substrate, the plugging cover is matched with the outlet of the guide tube so that the guide tube can be as opened and closed, and the sound insulation substrate, the installation clamping buckles, the guide tube and the plugging cover are formed through integrated injection molding; and the guide tube is provided with an inlet tube located at the upper surface of the sound insulation substrate and an outlet tube located at the lower surface of the sound insulation substrate, wherein the inlet tube is an elliptic cone tube which is large at the upper part and is small at the lower part. With the sound insulation rubber block adopted, the installation of a skylight drainage pipe is more convenient, and the guide tube will not be plugged by the foamed foaming material.
