Abstract
A flap ventlid installation assembly provided for installing a flap ventlid at an opening of an air removing hole on a design surface of a tire mold includes a flap ventlid and an anchor member. The anchor member includes a top portion connected to the flap ventlid, and a longer portion extending from the top portion to an opposed second end that has a first shape that cannot be inserted into the air removing hole without elastically deforming the first shape into a second shape that can be press-fit into the air removing hole. When the flap ventlid is installed in the tire mold, at least a part of the flap ventlid contacts the design surface of the mold when the anchor member is press fit into the opening such that the second shape engages a portion of the air removing hole proximate the other surface of the mold.
