  In literature usual point like symmetries of the Lagrangian have been
introduced to study the symmetries and the structure of the fields. This kind
of Noether symmetry is a subclass of a more general family of symmetries,
called Noether Gauge Symmetries (NGS). Motivated by this mathematical tool, in
this article, we discuss the generalized Noether symmetry of Quintom model of
dark energy, which is a two component fluid model of quintessence and phantom
fields. Our model is a generalization of the Noether symmetries of a single and
multiple components which have been investigated in detail before. We found the
general form of the quintom potential in which the whole dynamical system has a
point like symmetry. We investigated different possible solutions of the system
for diverse family of gauge function. Specially, we discovered two family of
potentials, one corresponds to a free quintessence (phantom) and the second is
in the form of quadratic interaction between two components. These two families
of potential functions are proposed from the symmetry point of view, but in the
quintom models they are used as phenomenological models without clear
mathematical justification. From integrability point of view, we found two
forms of the scale factor: one is power law and second is de-Sitter. Some
cosmological implications of the solutions have been investigated
