The invention provides a hot-press forming machine for an inelastic fabric. The hot-press forming machine comprises a hot-press die, wherein the hot-press die sequentially comprises an upper fixed plate, an upper push plate, an upper template, an upper specially-shaped pressing die and a lower specially-shaped pressing die from top to bottom, wherein the upper specially-shaped pressing die and the lower specially-shaped pressing die are used for pressing the fabric up and down; the upper fixed plate is fixedly connected with the upper template; the upper push plate is arranged between the upper fixed plate and the upper template in a manner of moving up and down; the upper specially-shaped pressing die is fixedly connected to the lower end of the upper template; the lower end of the upper push plate is fixedly connected with a thermal forming die; the thermal forming die penetrates through the upper template and the upper specially-shaped pressing die in the manner of moving up and down; the lower specially-shaped pressing die is provided with a through hole for pressing down the thermal forming die; a heating device capable of moving up and down is also arranged in the through hole in the lower specially-shaped pressing die. Compared with the prior art, the hot-press forming machine for the inelastic fabric is simple in structure and convenient to operate and can quickly form the inelastic fabric through hot press.
