1. A method for molding and forming a flip-flop comprising following steps of:
step A: adopting a mold for molding and forming the flip-flop, the mold having a mold chamber being shaped as the flipflop and divided into a sole area corresponding to a shape of a sole of the flip-flop, a strap area corresponding to a shape of an elongated V-shaped strap of the flip-flop, and three hole-shaped connecting areas communicating with the sole area and the strap area respectively and corresponding to positions of three end points of the V-shaped strap;
step B: positioning a mold for molding and forming the flip-flop at a mold clamping position;
step C: filling a rated amount of a polymer raw material into the mold chamber, the polymer raw material flowing downwardly through outlet orifices into the sole area of the mold chamber and flowing from the sole area through the three hole-shaped connecting areas into a space of the strap area, the space of the strap area being filled entirely with the polymer raw material before the sole area being filled entirely with the polymer raw material; and
step D: after reacting, foaming and forming of the filled polymer raw material in the mold chamber, opening the mold for molding and forming the flip-flop and taking out a finished product of the flip-flop;
wherein the finished product of the flip-flop being formed with a sole and a V-shaped strap, the V-shaped strap being a single piece integrally formed with the sole and having three end points connected to the sole.
