Abstract:
A flap ventlid installation assembly for installing a flap ventlid at an opening of an air removing hole that is formed on a design surface of a tire mold and extends in a longitudinal direction toward an opposed surface of the tire mold opposing the design surface said flap ventlid installation assembly comprising:a flap ventlid which functions as an opening and closing lid that passes or interrupts air flow at the opening of the air removing hole; and an anchor member, having a top portion which is connected to said flap ventlid and a longer portion that extends from said top portion to an opposed second end in the longitudinal direction of the air removing hole, said longer portion of said anchor member having a first shape proximate said second end thereof that cannot be inserted as it is into the air removing hole through the opening on the design surface of the tire mold without applying an external force to said first shape to cause elastic deformation of said first shape to form a second shape that can be press-fit into the air removing hole through the opening on the design surface of the tire mold; wherein said flap ventlid is adapted to be installed in said tire mold such that at least a part of said flap ventlid contacts the design surface of the tire mold when said anchor member is press-fit into the opening of the air removing hole on the design surface of the tire mold such that said second shape engages a portion of the air removing hole proximate the surface of the tire mold opposing the design surface.
