  In this paper, we have investigated some accelerating cosmological models at
the backdrop of an anisotropic metric in an extended gravity theory. Two viable
cosmological models one with a little rip behaviour and the other with a
hyperbolic form of Hubble parameter have been constructed. The dynamical
aspects of the models along with some physical and geometrical parameters are
analysed. Both the models presented here evolve in the phantom-like region and
overlap with $\Lambda$CDM model at late times. We carried out a geometrical
diagnosis of the model to show the viability of the models.
