The invention discloses a bicolour double-density block press, comprising two shoe moulds. Each shoe mould comprises a top mould, a side mould and a bottom mould; the shoe moulds are arranged on the same side of the block press; the bottom mould comprises a primary bottom mould and a secondary bottom mould; the primary bed mould and the secondary bottom mould are mounted on the mould frame and arranged on a bench of the block press through the mould frame; the bench of the block press is provided with a slide way or a chute for pushing or pulling the mould frame; a corresponding chute or a slide way is arranged at bottom of the mould frame; the pressure of the top mould or the top mould and side mould is controlled by a pressure regulator. The two shoe moulds are arranged on the same sideand can be operated by one operator, thereby enlarging the operation space, being convenient for operation and effectively improving the labor efficiency; as the primary bottom mould for stamping external bed charges and the secondary bottom mound for stamping internal bed charges are arranged, soles with two colors and hardness can be stamped on one block press, thereby the requirements for stamping different soles can be met.
